Abstract

 

Introduction: Cardiac decompensation factors are numerous. Their identification allows better management of patients and limits the rate of rehospitalization. The aim of this work was to identify cardiac decompensation factors and improve their management at the renaissance hospital in N’Djamena, Chad.

Patients and Methods: This was a cross-sectional retrospective study conducted in the cardiology department at N’Djamena Renaissance Hospital, over a period of one year, from 01 January 2018 to 01 January 2019. All patients hospitalized for cardiac decompensation during this period and consented, were included.

Results: During the period of our study, 52 patients were included. The sex ratio was 1.9. The mean age was 48±9 years old. The predominant cardiovascular risk factors were arterial hypertension (37%, n = 19) and diabetes (27%, n = 14). The monthly income of our patients was in the majority of cases less than 200,000 FCFA (44%, n = 23). The main factors of cardiac decompensation were respectively, infections (18%, n = 9), supraventricular arrhythmias (16%, n = 8), changes in temperature (11%, n = 6), therapeutic nonobservance (11%, n = 6), dietary gap (10%, n = 5), and hypertensive relapses (10%, n = 5). The main etiologies of heart failure were ischemic cardiomyopathies (31%, n = 16), dilated cardiomyopathies (25%, n = 13), hypertensive cardiomyopathies (17%, n = 9), and rheumatic valvulopathies (15%). %, n = 8).

Conclusion: Rehospitalizations for cardiac decompensation are common after the first episode of hospitalization. The identification of the risk factors for this decompensation and their management make it possible to avoid these readmissions.

Introduction

Heart failure (HF) is defined as a clinical syndrome characterized by chronic symptoms (dyspnea, fatigue) that may be accompanied by physical signs (crepitus, peripheral edema) caused by a structural cardiac abnormality and / or functional, resulting in decreased cardiac output [1]. It is a major public health problem because of its frequency and consequences in terms of morbidity and mortality and its economic impact on the health care system. Its prevalence is increasing because of the aging of the population but also because of the improvement of the management of many heart diseases including ischemic heart disease. It is one of the leading causes of hospitalization, morbidity and mortality, especially among the elderly [2]. Its evolution is clinically marked by periods of remission and exacerbation leading to recurrent hospitalizations. The number of readmissions for IC remains significant despite the therapeutic progress of recent years. The identification of decompensation factors and the optimization of their management could prevent these readmissions, particularly after hospitalization. The objective of this study was to identify cardiac decompensation factors and improve their management at the renal hospital in N’Djamena, Chad.

Patients and Methods

This was a cross-sectional retrospective study conducted in the cardiology department at N’Djamena Renaissance Hospital, over a period of one year, from 01 January 2018 to 01 January 2019. Were included all patients readmitted for cardiac decompensation during the study period and who gave their consent.

The parameters studied

Epidemiological characteristics: age, sex, cardiovascular risk factors (arterial hypertension, diabetes, chronic renal dysfunction with glomerular filtration rate <60ml/min / 1.73m2, obesity, dyslipidemia, alcohol, smoking), monthly cost of treatment in FFCA (1 US dollar = 593,720 FFCA). Clinical features: cardiac decompensatory factors (difference in diet, unsuitable exercise, temperature, alcohol, AFA, other rhythm disorders, hypertensive pressure, ischemic episode, anemia, bronchopulmonary infection, other infection, renal failure, poor compliance drug, hyperthyroidism, untreated sleep apnea syndrome), etiologies of HF. Electrocardiographic characteristics: arrhythmias (atrial or ventricular extrasystoles, atrial fibrillation or flutter, atrial tachycardia, ventricular tachycardia), repolarization abnormalities, sinoatrial or atrioventricular blocks. Echocardiographic features: dilated cardiac cavities, wall hypertrophy, diastolic dysfunction of the left ventricle (LV); abnormalities of left ventricular kinetics (hyperkinesia, hypokinesia, akinesia), LV systolic dysfunction (systolic ejection fraction <45%), valvular abnormality, congenital anomaly, pulmonary arterial hypertension.

Statistical Analysis

In this study, a descriptive statistical analysis was applied using Microsoft Excel, quantitative variables were presented by their mean and standard deviation and qualitative variables were by percentages.

Ethics

This work was done by obtaining the approval of the hospital management and the consent of the patients.

Results

During the period of our study, 52 patients were included. Men predominated with 65% of cases (n = 34). The sex ratio was 1.9. The average age was 48±9 years old with a minimum age of 22 years and a maximum age of 79 years. Patients were educated only in 38% of cases (n = 20). The predominant cardiovascular risk factors were hypertension (19%), diabetes (14%), dyslipidemia (11%), and 19%). The monthly income of our patients was in the majority of cases less than 200,000 FCFA. The rates were, respectively, between CFAF 100,000 and 200,000 in 44% of cases (n =23) and less than CFAF 100,000 in 33% of cases (n = 17). Only 12 patients (23%) had an income above 200,000 FCFA. The health insurance rate was observed in 13% of cases (n=7). (Table 1) shows the characteristics of the patients. The main factors of cardiac decompensation are shown in Table 2. The most frequent were respectively, infections in 18% of cases (n = 9), including 4 cases of bronchopulmonary infections (8%), supraventricular rhythm disorders in 16% of cases (n=8) including 5 cases of AFA (10%), changes in temperature especially heat with 6 cases (11%), poor therapeutic compliance 6 cases (11%), the difference diet in 10% of cases (n = 5), and hypertensive outbreaks in 10% of cases (n=5). The most common etiologies of IC (Table 3) were ischemic cardiomyopathies in 31% of cases (n=16), of which 4 patients (8%) had benefited from myocardial revascularization, dilated cardiomyopathies in 25% (n=16). = 13), hypertensive cardiomyopathies in 17% of cases (n =9) and rheumatic valvulopathies in 15% (n=8). Other etiologies were less frequent in this series such as post-embolic pulmonary heart in 6% of cases (n=3), congenital heart disease in 4% (n=2) and pericardial affections in 2% of cases (n= 1).

Discussion

The post-hospitalization period is conducive to rehospitalization, but long-term chronic HF patient follow-up is important because the morbidity and mortality rate remains high in this group of patients, even though many treatments have been shown to be effective. The follow-up of these patients makes it possible to optimize the therapeutics, the monitoring and to detect early the signs of decompensation. Cardiac rehabilitation plays an important role in the management of HF and should be part of the modern strategy for the management of patients with stable heart failure. This includes not only physical training, but also rehabilitation of drug treatments, control of risk factors, psychological management and finally, patient education [3]. The search for this factor that shifts a situation of balance during a decompensation is fundamental because its treatment can be very profitable. Several standards for HF support highlight the need to look for a triggering factor [4]. We studied the importance of triggers for cardiac decompensation in a population of readmitted patients who were followed for chronic HF. The main triggering factors identified were, in order of frequency, infections, atrial fibrillation, therapeutic nonobservance, temperature variations, mainly heat, uncontrolled hypertension, diet deviation, anemia, myocardial ischemia. These factors are globally found in the literature data. In this study, the first triggering factor found was the existence of an infection (18%) with bronchopulmonary infections (8%) at their head. They are promoted by decreasing the effectiveness of coughing, bronchiolar elasticity, efficiency of the mucociliary system and swallowing disorders.

The mechanisms involved in cardiac decompensation are multiple. Several studies have highlighted the important role of infections, particularly bronchopulmonary infections, in cardiac decompensation, especially in elderly patients [5-8]. The second triggering factor was a supraventricular rhythm disorder (16%), especially ACFA (10%). Suppression of atrial systole results in increased LV filling pressures and promotes the onset of HF thrust. AFA is common in HF and its prevalence increases with the severity of CI [9-13]. Cardiac decompensation was attributed to noncompliance in 8% of the cases in this study, but adherence remains difficult to assess. This non-compliance was favored by several factors in our patients; the high number of drugs with their adverse effects, given the high rate of comorbidities observed (diabetes, high blood pressure, kidney failure), the economic level which was low in almost 50% of patients and the absence of health insurance, the level of education and the influence that might have on the understanding of the disease. The therapeutic nonobservance in the HF varies in the literature from 10 to 99% according to the evaluation method used [14]. Compliance is responsible for an increase in the number of hospitalizations and a worsening of clinical signs [15]. A multidisciplinary intervention has shown its effectiveness on adherence to 30-day treatment [16] and an educational intervention has improved compliance and decreased re-hospitalization rates [17]. Anemia was found in 4 patients in our series.

This result is weak compared to data from the literature because, according to several authors, anemia is frequent during IC and is a poor prognostic factor in chronic HF [18,19], increased clinical signs, aggravation of functional status [20]. However, there is little data on the involvement of acute anemia in cardiac decompensation. In addition, the management of the etiology of HF remains essential to prevent complications and readmissions and to improve the prognosis. In our study we found that in coronary patients (31%) only 8% had benefited from myocardial revascularization, valvular patients (15%) and those with congenital heart disease (4%) had not received reparations. surgical procedures that were necessary. In our context, the identification of the decompensation factors must be of paramount importance for the clinician and should allow the improvement of the management of the pathology in particular at the preventive level. Hence the importance of educating the patient and those around him. The establishment of appropriate structures and care networks for heart failure in all regions of Chad will allow better monitoring of patients with rapid access to the specialist physician.

The limits of our work

Our study presents several methodological limitations. First, it is a retrospective study with information gathered from the reports that sometimes did not contain all the necessary data. The size of our sample is small, we will have to lead other more representative studies in the future. And many patients have not received etiologic treatment of HF.

Conclusion

Rehospitalizations for cardiac decompensation are common after the first episode of hospitalization. The identification of the risk factors for this decompensation and their management make it possible to avoid these readmissions. Hence the importance of emphasizing access to care with appropriate therapeutic means, regular monitoring and therapeutic education.

Lupine Publishers | Relationship between Depression and Physical Activity of Myocardial Infarction Patients after Treatment

Lupine Publishers | Advancements in Cardiology Research & Reports

 

 

Abstract

 

Physical activity is a secondary prevention that can reduce mortality and re-admission in patients with myocardial infarction. The objective of this study was to identify the relationship with physical activity of myocardial infarction patients after treatment. This study used a cross sectional method. A total of 150 myocardial infarction patients were selected using a purposive sampling technique. The results showed that the majority of STEMI post-treatment patients have mild physical activity (82%). There is also a significant relationship between depression and the level of physical activity of myocardial infarction patients after treatment (p = 0.003), OR = 0.144 (95% CI; 0.032-0.635). Depression in myocardial infarction patients at the time of the attack, if not intervened properly, it will persist and affect physical activity after treatment. A recommendation is directed to the nursing department to assess depression in patients with newly diagnosed of myocardial infarction.

Keywords: Physical activity; myocardial infarction; depression in myocardial infarction patients

Background

Physical activity is recommended by the European Society of Cardiology (ESC) as a long-term therapy in prevention for myocardial infarction patients Ibanez et al. [1]; Amsterdam et al. [2]. Physical activity can reduce mortality, re-admission and improve the quality of life of patients with myocardial infarction Andersen & Laustsen, [3]; Dalal, et al. [4]; Ek et al. [5]. Although physical activity is recommended as a long-term therapy in STEMI patients, only 37% of patients actively engage in physical activity after treatment Mckee et al. [6]. Several factors are known to have an association with physical activity in myocardial infarction patients, one of which is depression Mckee et al. [6]. Depression in myocardial infarction patients occurs 48-72 hours after a heart attack Kala, et al. [7]. Depression has a negative effect on post-treatment recovery in myocardial infarction patients, and causes lower compliance to treatment programs Homma et al. [8]; Kumar et al. [9]. The objective of this study was to identify the relationship between depression and physical activity of patients with myocardial infarction after treatment.

Method

This design of the study was a cross sectional study. Sampling was carried out using non-probability sampling techniques with a sample of 150 people. The inclusion criteria in this study were patients aged ≥18 years who were diagnosed with myocardial infarction. The study was conducted at the regional hospital of Jambi province, Indonesia in February - March 2018. Data collection was done using PHQ-9 Patient Depression Questionairre Kroenke et al. [10] and International Physical Activity Questionnaire (IPAQ) Strath et al. [11].

Findings

Characteristics of Respondents

Of the 150 post-treatment STEMI patients, the majority of patients were aged 18-60 years (73.3%), were male (78.7%), and 75.3% of whom had passed 7 to 30 days post-treatment. The majority of respondents were in the category of mild depression 69.3%, whereas the rest experienced moderate-severe depression, and 82% of respondents were at the level of physical activity with mild categories. Relationship between depression and physical activity of post-treatment myocardial infarction patients. The results of the analysis of the relationship between depression and physical activity showed that 95.7% of post-treatment myocardial infarction patients experienced moderate-severe depression with mild physical activity. Meanwhile, among post-treatment myocardial infarction patients who experience mild depression, 24% had moderate-heavy physical activity. Fisher exact test results obtained p = 0.003, so it can be concluded that there is a relationship between depression and physical activity. From the results of the analysis also demonstrated that the value of OR is 0.144 (95% CI; 0.032-0.635). By looking at the OR values it can be concluded that post-treatment myocardial infarction patients who experience mild depression would have a 0.144 times greater chance of having moderate-heavy physical activity compared to patients who have moderate-severe depression category

Discussion

Physical activity is a key component in heart disease patients that is beneficial in reducing the risk of relapse Thompson et al. [12]. In this study, the results of the analysis showed that 82% of respondents are at the level of mild physical activity. The results of this study are similar to studies conducted by Matthias, 2017 in Sri Lanka, where 56, 7% of respondents had low physical activity Matthias et al. [9]. Low physical activity is a trigger for the occurrence of myocardial infarction. Physical activity increases the process of arteriosclerosis formation, decreases inflammation, and triggers the formation of thrombosis Cheng et al. [13]. Many factors can affect physical activity. The study of Mckee et al. [6]. concluded that depression was one of the dominant factors causing low physical activity. This is the same as the results of this study. The results of bivariate testing found a relationship between depression and physical activity. Patients with myocardial infarction who experience depression tend to smoke, have low physical activity, and consume a lot of alcohol Qing Wu et al. [14]. In addition, experience during an attack is a cause of depression, and this continues for up to two months after the attack. This state of depression results in the patient becoming silent and limiting their physical activity.

Conclusion

Post-treatment myocardial infarction patients have a mild level of physical activity, and depression during the attack still occurs in myocardial infarction patients after undergoing treatment in the hospital. Depression, if not properly intervened, will cause changes in physical activity of myocardial infarction patients after treatment.

Abstract

Background: Coronary anomalies are the causes of sudden cardiac deaths in young peoples, but usually asymptomatic. We perform this retrospective study to determine the types and prevalence of Coronary Anomalies of origin and course.

Method: The data of 9572 patients with Coronary CT-angiography by MDCT 640 Aquilion Toshiba machine were analyzed.

Results: Anomalous origin and course of coronary artery were detected in 47 (0.49%) of 9572 patients. The anomalous origins of Circumflex Artery from the RCA or the right sinus of Valsalva are most frequently visualized ( 15 pts [31.9%] ). High taking off of RCA observed in 11 pts ( 23.4% ).The RCA rising from the left sinus of Valsalva were seen in 8 pts ( 17% ).The Left Coronary Artery originates from the right sinus of Valsalva in 5 pts ( 10,6% ).The RCA arising from the LAD in 2pts (4,2% ).Absent RCA in 2 case (4.2%) and single coronary artery from LSV in one case (2.1%). The LCA rising from the Pulmonary Artery ( ALCAPA) in 2 cases and The RCA originating from the PA in one case ( RCAPA ).

Conclusion: Anomalies of coronary artery origin and course are rare but the diagnosis is very important to prevent SCD in young patients. MDCT with the Volume Rendered Images is the non-invasive modality that provides the valuable information to detect these anomalies.

Keywords: Multidetector Computed Tomography; Anomalies of coronary origin and course; sinus of Valsalva

Introduction

Coronary artery anomalies are a diverse group of congenital heart diseases with manifestations and pathological mechanisms are highly variable. Coronary anomalies include anomalies of origin and course, anomalies of intrinsic coronary arterial anatomy like myocardial bridge, anatomy of coronary termination as coronary artery fistula and anomalous anastomotic vessels. Anomalies of coronary origin and course may associated with arrhythmias, myocardial infarction and sudden cardiac deaths in young people, especially on effort like athletes. We study 9572 patients with coronary MDCT-angiography to evaluate the type and the incidence of coronary anomalies of origin and course[1,2].

Methods

All patients who underwent coronary CT-angiography by MDCT 64O Aquilion Toshiba equipment ( IV contrast medium, gantry rotation of 0.33 msec, slice thickness 0.5mm ) in MEDIC HCMC Viet Nam, from January 2016 to January 2019 were included. The main indications of CT-angiography were acute coronary syndrome, stable angina, coronary CT-angiography prior to surgery, congenital heart diseases involving coronary artery...

The CT-angiograms with coronary anomalies were selected and analyzed. The anomalies of coronary origin and course were assessed [3-5].

Results

We included 9572 pts with anomalies of coronary origin and course based on results of CT-angiograms that were interpreted by two cardiologists. Anomalous origin and course of coronary artery were detected in 47 ( 0,49 %) of 9572 patients. The mean age of these pts was 63± 8.4, M/F=1.8 . The anomalous origins of Circumflex Artery from the RCA or the right sinus of Valsalva are most frequently visualized ( 15 pts [31.9%] ).High taking off of RCA observed in 11 pts ( 23.4% ) The RCA rising from the left sinus of Valsalva were seen in 8 pts ( 17% ).The Left Coronary Artery originates from the right sinus of Valsalva in 5 pts ( 10.6% ), in this subgroup, a patient presented by myocardial infarction resulting cardiac arrest was notified, the surgical re-implantation of LCA was performed .The RCA arising from the LAD in 2pts (4,2% ). Absent RCA in 2 case (4.2%) and single coronary artery from LSV in one case ( 2.1% ) (Table1 ).The Left Coronary Artery arising from the Pulmonary Artery ( ALCAPA ) in 2 cases ( 4.2% ) and The RCA originating from the PA ( RCAPA ) in one case ( 2.1% ). sinus of Valsalva (Figures 1-10).

Discussion & Conclusion

In our study, coronary anomalies of origin and course were detected in 47 of 9572 patients ( 0,49% ) that is consistent with the incidence of 0.27% to 1.66% reported in other series. The most frequent anomaly of origin and course was the Cx Artery arising from RCA/RSV ( 31.9% of anomaly prevalence and 0.16% among all patients ), this incidence is lower than previous published studies. The anomalies of origin and course of RCA were found in 17% and 4.2% respectively from LSV and LAD. This incidence is lower in comparison with previous study. Sudden deaths, myocardial infarction, arrhythmias related to the coronary anomalies were reported previously [6,7]. But these anomalies often asymptomatic, so early detection of coronary anomalies of origin and course is highly important. The former studies mainly based on the result of coronary angiography that is invasive modality. This study demonstrates MDCT is the noninvasive modality that provides important information related to coronary anatomy. Currently MDCT and MRI become fundamental to detection and diagnosis of coronary anomalies. Contrast enhanced ECG-gated 640-row MDCT coronary angiography is an accurate diagnostic method that can precisely detect the coronary anomalies of origin and course.

Keywords: Congenital heart diseases; Cardiac multi-detector computed tomography, Multi-detector computed tomography in congenital heart diseases; Congenital heart diseases computed tomography

Introduction

Congenital heart diseases effect ~ 1% of all live births in the general population. Complex congenital heart diseases associated with more malformations, complex aortopulmonary collaterals and anomalous coronary artery. Over the past few decades, the diagnosis and treatment of congenital heart diseases have greatly improved [1-6]. Diagnostic tools: X-ray, ECG, echocardiography, MRI and MDCT. ECG and X-Ray suggest the diagnosis but are not specific. Echocardiography is the initial diagnostic method for patients with suspected CHD but this method can be limited in complex CHD. The great capabilities of MRI for anatomic and functional assessment of the heart but MRI is time-consuming and may require patient sedation. Now enable CT to be used as an accurate noninvasive clinical instrument that is fast replacing invasive cine-angiography in the evaluation of CHD [1,2,5].

Lupine Publishers | The Left Common Carotid Artery Rises from the Main Pulmonary Artery

Lupine Publishers | Advancements in Cardiology Research & Reports

Abstract

A young female patient of 15y.o presented at my hospital by dyspnea on effort and palpitation for one year. Mental deficiency was notified. Physical examination detected a 3/6 continuous murmur at the 2ndRICS. In the past history, PDA had been suspected by her physician, associated with recurrent bronchitis. Trans-thoracic Echocardiography showed an enlarged LV of 57mm with normal EF of 69% , LCA=5mm, RCA=3.5mm at origin, no suspected sign of PDA was seen. Only a continuous flow was visualized in the PA. CT-Angiography with IV contrast medium showed the Left Common Carotid Artery rising from the Pulmonary Artery trunk. PDA was not presented. The Left Common Carotid Artery then was re-implanted into the aortic arch normally with a favorable postoperative progress.

Keywords: Carotid Artery; Pulmonary Artery; Anomalous origin

Introduction

Anomalous origin of the left common carotid artery is very rare and has been reported previously. We present an operated case of this topic with clinical finding, cardiac ultrasound and MDCT imaging.

Case Report

Figure 1: Right aortic Arch.

A young female patient of 15y.o presented at my hospital by dyspnea and palpitation when running and fast walking for one year. Mental deficiency was notified, she had some difficulties to learn at school. Physical examination detected a 3/6 continuous murmur at the 2ndRICS. In the past history, PDA has been suspected by her physician, associated with recurrent bronchitis. Her body state was normal with 1m60 of height and 48 kg of weight. She was evaluated immediately by a chest X ray that showed a right aortic arch (Figure 1). The trans-thoracic echocardiography that revealed an enlarged LV of 57mm with normal EF of 69% (Figure 2), LCA=5mm, RCA=3.5mm at origin (Figure 3). No suspected sign of PDA was detected except a continuous flow presented in the Pulmonary Artery (Figure 4).

Figure 3: Normal LCA at origin.

Figure 4: Continuous flow in the PA.

Figure 5: Absence of aortic origin of the LCCA.

CT-Angiography (MDCT 64) with IV contrast medium Ultravist, slice thickness=1mm visualized a right aortic arch, aberrant origin of the left subclavian artery, dilatation of the branches rising from aortic arch with increased collateral vessels (Figure 5). Especially, MDCT 64 showed the Left Common Carotid Artery ( LCCA ) rose from the PA trunk (Figure 6) PDA was not detected. Patient underwent uncomplicated surgical repair: the Left Common Carotid Artery was re-implanted into the aortic arch normally with a favorable post-operative progress (Figure 7).

Figure 6: The LCCA rising from the Main PA roof.

Figure 7: Re-implantation of the LCCA.

Discussion

Anomalous origin of the Left Common Carotid Artery from the Pulmonary Artery Trunk has been previously reported as rare cases. Kagami Mijaji et al. [1] has reported a case of anomalous origin of the Artery from the Right Pulmonary Artery. Onyekachukwu et al. [2] has described a case of anomalous origin of the Left Common Carotid Artery from the Main Pulmonary Artery. In this article, my patient was not infant with CHARGES syndrome that includes multiple congenital anomalies like the patients in their reports. She was a teenage patient without other congenital disease. The role of ultrasound is orienting for the indication of Computed Tomography or DSA. In case of present turbulent flow in the PA, Coronary Fistula and other shunts from the head and neck vessels should be considered [3].

Conclusion

Anomalous origin of the Left Common Carotid Artery is very rare congenital defect that maybe isolated or associated with some syndromes. Noninvasive diagnostic methods as Ultrasound and CTA may confirm the diagnosis and inform the anatomical relation of the anomalous vessels prior to operate.

Abstract

 

Introduction: A great number of the studies have shown that platelets play a role in closure of the PDA. However, studies that reported that platelet parameters were not associated with PDA were also published. We also wanted to contribute to clarify the relationship between PDA and platelet parameters.

Materials and Methods: Preterm infants that less than 34 gestational weeks were examined to echocardiography at the time of detected clinical findings or within 24-72 h after admission to our unit, routinely. The patients were divided into two groups according to echocardiography findings randomly; hsPDA require ductal closure treatment and non-hsPDA. The platelet count, MPV, PDW, PCT and Platelet Mass Index values of both groups were compared.

Results: There was no difference between the two groups in terms of MPV, Platelet count and Platelet mass index. However, PDW and PCT were statistically significantly in the study group than the control group.

Discussion: As a result, according to our study, platelet count, MPV and platelet mass index cannot be used to predict either hsPDA or treatment success, but a low PCT and high PDW can be used predict hsPDA but not treatment success.

Introduction

Patent Ductus Arteriosus (PDA) can cause mortality and morbidity such as respiratory distress syndrome (RDS), pulmonary hemorrhage, bronchopulmonary dysplasia (BPD), intraventricular hemorrhage (IVH), necrotizing enterocolitis (NEC), retinopathy of prematurity (ROP) [1]. For this reason, early diagnosis and treatment of PDA is the most important point. The main diagnostic method of PDA is Doppler echocardiography [2]. However, there is no clearly consensus on diagnosis of hemodynamically significant patent ductus arteriosus (hsPDA). Therefore, new diagnostic methods of PDA are needed. A great number of the studies have shown that platelets play a role in closure of the PDA [3-6]. The first of these studies, Echtler et al. studied the relationship between ductal closure and platelet parameters in animals [3]. In the same study, the ductus arteriosus did not close (thus, remained permanently open) in animals in which platelet functions were compromised. After this study, they studied on premature infants about relationship between ductal closure and platelet parameters. According to this study, a low platelet count and a low PDW were risk factors for PDA. However, studies that reported that platelet parameters were not associated with PDA were also published [7-11]. We also wanted to contribute to clarify the relationship between PDA and platelet parameters.

Materials and Methods

This observational, retrospective cohort study was conducted between August 2017 and 2018. Preterm infants that less than 34 gestational weeks were examined to echocardiography at the time of detected clinical findings or within 24-72 h after admission to our unit, routinely [12]. The patients were divided into two groups according to echocardiography findings randomly; hsPDA require ductal closure treatment and non-hsPDA. hsPDA was defined when at least one of the clinical findings associated with PDA was present: a hyperdynamic precordium; a sustained murmur; tachycardia; hypotension; oliguria; an increased pulse pressure; an increase in ventilation pressure and/or oxygen demand; and at least one echocardiographic finding: ductal diameter ≥1.5mm, left atrium/ aortic root ratio ≥1.5, and/or diastolic flow failure in the abdominal aorta or inverse flow. We applied intravenous or oral ibuprofen to close the hsPDA. Intravenous or oral paracetamol was given in cases who ibuprofen is unsuccessful or contraindicated. After treatment, echocardiography was performed again, and the PDA was classified as open or closed. We excluded those with conditions that might cause inflammation or affect platelet count and/or function (Antenatal steroid use, PPROM, early sepsis, chorioamnionitis, congenital viral infections, preeclampsia), congenital heart disease, pulmonary hypertension, perinatal asphyxia, congenital anomaly, chromosomal anomaly, thrombocytopenia (<50.000/mm3), and lack of data. Written informed consent was obtained from all parents. All echocardiographic examinations were performed by Vivid S6 Echocardiography System fitted with a 10S transducer (General Electric Healthcare, Milwaukee, WI, USA). Blood samples taken from an umbilical venous catheter at between 48-72 hours and 7. day, were collected in ethylenediaminetetraacetic acid-containing tubes and blood counts performed using a Coulter Counter model LH (Coulter Electronics, Hialeah, FL, USA). This yielded the platelet count, MPV, PDW, PCT. The platelet mass index was obtained from the platelet count (10³/mm³) and the MPV (fL). We recorded gestational age, birth weight, sex, mode of delivery, Apgar scores (at 1 and 5 min) 48-72 h and 7. day platelet parameters, surfactant requirement, ventilation history, IVH, NEC, ROP, BPD, duration of hospitalization and any death.

Statistical Analysis

Statistical analyses were performed using SPSS for Windows ver. 22.0 (SPSS Inc., Chicago, Illinois). The paired samples t-test and independent samples t-test were used to compare continuous variables. Continuous variables are presented as means ± SDs, and categorical variables are given as frequencies with percentages. A p-value less than 0.05 was considered statistically significant.

Results

258 newborns under 34 weeks were admitted to our unit, of whom 121 were excluded. The study group consisted of 72 premature infants with hsDPA who applied ductus closure treatment and 65 premature infants without hs DPA or spontaneously closed PDA consisted of the control group (Figure 1). The demographic characteristics of both groups are shown in Table 1. The mean gestational age and the mean birth weight of the study and control groups were, respectively, 31.4±3.8 vs. 32.3±4.5 weeks (p=0.12); 1441±347 vs. 1,539±286g (p=0.08). There was no difference between two groups in perinatal parameters. The platelet parameters of both groups are shown in Table 2. There was no difference between the two groups in terms of MPV, Platelet count and Platelet mass index. However, PDW and PCT were statistically significantly in the study group than the control group.

Discussion

Low oxygen pressure, elevated prostaglandin and nitric oxide levels are the main factors affecting continuity of the ductus arteriosus in the uterus. After birth, increased oxygen levels and decreased prostaglandin levels enable functional closure of the DA [13]. In addition to this mechanism, different mechanisms of closure of the ductus began to be discussed. The discussion began when Echtler et al. showed that platelets were attached to the lumen of the closed ductus arteriosus and confirmed this experimental finding via a retrospective study of preterm births [3]. After this animal study, various hypotheses about the role played by platelets in duct closure in newborns have been proposed. The most acceptable hypothesis is an effect of platelets on DA contraction, which occurs immediately after birth in term newborns, triggering hypoxia in the vessel wall by decreasing the blood flow in the venous lumen and vasa vasorum; in preterm newborns, the cells in the ductus wall are fed by the ductal lumen because of the absence of a vasa vasorum. As the ductus wall is thin, contraction is inadequate and endothelial damage and platelet aggregation thus develop because of vesselwall hypoxia. Based on this hypothesis, it was claimed that platelet counts were important in terms of DA closure in preterm infants, as they are in the pathophysiology of adult vascular diseases [14,15]. However, this hypothesis is not supported by the fact that platelet transfusion does not reduce the incidence of PDA in preterm newborns with immune thrombocytopenia and does not increase the PDA frequency in term newborns with severe thrombocytopenia secondary to Wiskott-Aldrich syndrome [16-20].

In Fujioka et al. [21-23]. the platelet count was not related to PDA diagnosis or treatment success. On the other hand, Echtler et al. [3,5,6] reported that a low platelet count increased the hsPDA incidence [24-25]. In some works performed after these contradictory studies, it was reported that large platelets create a greater potential risk of prothrombotic reactions; large platelets are more aggregated than small and normal platelets given the greater number of receptors such as thromboxane A2-B2 and glycoproteins IIb-IIIa on the surfaces of large platelets. It was suggested that the increased metabolic and enzymatic activities of dysfunctional thrombocytes, rather than the platelet count, were associated with PDA [26-29]. We sought to identify parameters related to platelet function associated with PDA. These remain controversial; all of MPV, PDW, PCT, and platelet mass index have been associated with cardiovascular diseases in adults [30-35]. In addition, in a limited number of studies on neonates, the MPV and PDW were shown to be associated with prematurity complications such as RDS and BPD [36-37].

In our study, no difference was found between the platelet counts of the hsPDA and control groups at 48-72 h and 7. day. In addition, there was no difference between the platelet counts of newborn who did and did not fail treatment. In conclusion, the platelet count was not a predictor of hsPDA diagnosis or treatment success. The results of our study contradict those of the two major meta-analyses conducted by Simon et al. and Mitra et al. but support the cohort study of Sallmon et al. [18-20]. PCT was lower and PDW was higher in the study groups than control groups and the difference between the two groups was statistically significant. However, MPV and platelet mass index were similar in both groups. Thus, we conclude that the PCT and PDW can be used to predict hsPDA but not treatment success. Demirel and Dizdar et al. [4]. reported that the PDW was higher in preterm infants with hsPDA than in control groups [38,39]. Bekmez et al [40]. reported that a low PCT increased the hsPDA incidence Demir et al.[41]. found a high MPV and a low platelet mass in the hsPDA group. We also excluded patients who received ibuprofen as ductus closure therapy because of potential effects on platelet count and functions. Infants born to mothers with prior pre-eclampsia, which affects platelet count and ductal flow because of the increased placental resistance, were also excluded [42-44]. We also excluded infants with perinatal asphyxia associated with an increased PDA, thrombocytopenia, and platelet dysfunction [45-47]. Newborns whose mothers had earlier received steroids were excluded because of possible effects on the platelet count. We thus excluded all pathologies that may affect platelet count and function and induce inflammation. There were some limitations of our study. The first limitation of our study is that it was retrospective in nature. The second limitation is modest sample size. As a result, according to our study, platelet count, MPV and platelet mass index cannot be used to predict either hsPDA or treatment success, but a low PCT and high PDW can be used predict hsPDA but not treatment success.
