[Elite athletes' electrocardiogram in Bobo-Dioulasso, Burkina Faso]. / Electrocardiographie du sportif de haut niveau d'entrainement à Bobo-Dioulasso, Burkina Faso.

High-performance sport results in electrocardiographic changes. Some are benign, other can cause sudden death. The purpose of this study is to describe the features of electrocardiogram at rest in elite athletes living in Bobo-Dioulasso. We conducted a cross-sectional descriptive study in the Department of Cardiology at the Souro Sanou University Hospital in Bobo-Dioulasso from August 2015 to February 2016. Elite athletes aged 17 to 35 years who had been training at least eight hours per week for more than six months, regardless of the type of sport, were enrolled. Two hundred elite athletes from four different sporting disciplines were included. The average age of athletes was 24 years (IIQ: 21-27). The median seniority in sport practice was 6 years (IIQ: 4-8) and the median duration of weekly training was 10 hours (IIQ: 10-10). Only 4% of the athletes had already undergone electrocardiogram. ECG showed abnormalities in 90.5% of cases and sinus bradycardia was the most common abnormality in 72.5% of cases. Left ventricular hypertrophy and left-atrial dilatation were reported in 44% and 34.5% respectively. Early repolarization syndrome was found in 47% of cases. In athletes, high-performance sport can result in electrical modifications. Practitioners need to know them in order to differentiate them from heart disease.

[Prevalence and knowledge of arterial hypertension in the elderly: cross-sectional study conducted in Bobo-Dioulasso, Burkina Faso]. / Prévalence et connaissances de l'hypertension artérielle chez les personnes âgées: étude transversale menée à Bobo-Dioulasso, Burkina Faso.

This study aims to determine the prevalence of arterial hypertension (AH) in the elderly people as well as their knowledge of this disease. We conducted a cross-sectional, descriptive study in the town of Bobo-Dioulasso from October to November 2015 at the intervention sites of the Association of Medical Assistance to elderly people "KAFOLI". Patients aged 60 years and more, with or without hypertension, who wished to participate in the study were included. Subjects were considered to be hypertensive when they had systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥90 mmHg or when they were under antihypertensive treatment. Socio-demographic and clinical data as well as the risk factors associated with the disease were collected. Knowledges on arterial hypertension were based on general knowledges about arterial hypertension as sources of information about it. A total of 88 subjects were included in this study. The study involved 56 women and 32 men (sex ratio 0.57). The average age of patients was 71 years (IQR:66-76). The prevalence of arterial hypertension was 61,36% and it was associated with knowledges about AH and with alcohol consumption; 68.18 % of patients had knowledge of AH. The majority of them were followed up in first-level health care nursing centres (64,81%). This study highlighted a high prevalence of hypertension in elderly people living in Bobo-Dioulasso. The majority of these persons were aware of this disease. In the majority of cases follow-up was ensured by nursing staff.

[Electrocardiography coupled with transthoracic echocardiography at rest in the diagnosis of cardiac impairments in type 2 diabetics: lessons learned from a cross-sectional case series in Burkina Faso]. / Electrocardiographie couplé à l'échocardiographie transthoracique de repos dans le diagnostic des atteintes cardiaques chez le diabétique de type 2: les enseignements d'une série transversale au Burkina Faso.

Diabetes is a powerful independent cardiovascular risk factor. The aim of this study is to describe the electrocardiographic and echocardiographic abnormalities observed in patients with type 2 diabetes treated in the Department of Medicine at the University Hospital in Bobo-Dioulasso. We conducted a descriptive cross-sectional study of all patients with type 2 diabetes who gave consent from April to September 2014. We gathered clinical data from all the patients. They, moreover, underwent electrocardiography and doppler echocardiography. A total of 155 diabetics were investigated. The average age of patients was 55 years (IQR: 47-64) with a female predominance (sex ratio 0.5). Electrocardiographic abnormalities included repolarization abnormalities (31%) and atrial rhythm disorders (16,12%). Echocardiographic examination showed left ventricular hypertrophy (LVH) in 20,64% of cases. Left atrium was dilated in 14.19% of cases, LV was dilated in 1.3% of cases. Abnormal left ventricular ejection fraction was detected in 3.87% of cases. Nosological entities included hypertensive heart disease in 27 cases (54%), ischemic heart disease in 19 cases (38%), dilated cardiomyopathy in 2 cases (4%) and diabetic cardiomyopathy in 2 cases (4%). Heart failure was detected in 22 cases (44%) independently from cardiac impairment. Electrocardiographic and echocardiographic abnormalities are frequent in type 2 diabetes population at the University Hospital in Bobo-Dioulasso. Improved cooperation between cardiologists and diabetologists as well as the establishment of adequate technical screening equipment would be prerequisite for better cardiac risk stratification in this population.

[Cardiopathies in children hospitalized at the University hospital Souro Sanou, Bobo-Dioulasso: echocardiographic and therapeutic aspects]. / Les cardiopathies de l'enfant au CHU Souro Sanou de Bobo-Dioulasso: aspects échocardiographies et thérapeutiques.

Children's heart diseases in Africa represent a public health problem that is difficult to cope with due to young population density, low socioeconomic status and lack of suitable technical platforms. This study aims to highlight the echocardiographic and therapeutic aspects of cardiopathies in children hospitalized at the pediatric department of the University Hospital Souro Sanou, Bobo-Dioulasso. We conducted a descriptive cross-sectional study over the period January 2013-December 2014 (24 months). It was based on a literature review of echocardiography reports performed on children under 15 years of age in the echocardiography laboratory of CHUSS and of medical records of their therapeutic follow-up. During the study period, 184 echocardiographic examinations were performed and allowed identification of 93 cases of children with heart disease (50.50% of cases). Among them, 71% (66/93) of cases with congenital cardiopathies were distinguished and 29% (27/93) of acquired cardiopathies. The most common congenital heart diseases were: IVC (27.2%), IAC (10.6%), AVC (7.5%), F4T (9.1%), CAT (6%), related forms ( 15%). Acquired heart diseases were dominated by rheumatic valve diseases (48%), hypokinetic dilated cardiomyopathy (33.3%) and pericardial tamponade (18.5%). Surgery was recommended in 53.7% (50/93) of cases, of whom 86% (43/50) with congenital heart diseases and 14% (7/50) with acquired heart diseases. 21% (9/43) of patients with congenital heart diseases underwent cardiac surgery. No acquired heart disease requiring surgery was surgically treated. Cardiopathies in children are frequent in Bobo-Dioulasso. Multidisciplinary strategies associated with resource optimization should improve the management of these cardiopathies.

Epidemiological and clinical features, ultrasound findings and prognosis of right-sided infective endocarditis in a teaching hospital in Ouagadougou.

INTRODUCTION: Right-sided infective endocarditis is rare. It accounts about 5 to 10% of all infective endocarditis cases and is prevalent in patients with congenital heart disease, intravascular devices and drug addiction. Our study aimed to describe the epidemiological, clinical and echocardiographic characteristics of right-sided endocarditis and evaluate the prognosis after treatment. METHODS: From January 2010 to December 2011 we recruited all patients admitted to Yalgado Ouedraogo Teaching Hospital for infective endocarditis, and selected those who had a right-sided location. The Duke criteria were used for diagnosis. We analysed entry points and underlying heart disease. The causative organisms were tracked using blood sample cultures. Ultrasound characteristics were described, and treatment and prognosis were evaluated. Patients' follow up was conducted from recruitment to 30 June 2012. RESULTS: In the two-year period, 14 cases of right-sided infective endocarditis were recorded, including seven cases in children. They accounted for 29.1% of all infective endocarditis cases. The mean age was 25.5 ± 12.5 years (range 9-80 years). The venous route was implicated in 12 cases (85.7%). Blood cultures were positive in 11 patients. The bacteria isolated were Streptococcus pneumonia in six cases, Staphylococcus aureus in three and Hemophilus influenza in two cases. HIV status was positive in three patients. Underlying heart diseases were dominated by congenital heart disease in six cases and peripartal cardiomyopathy in four others. Vegetations were located in the right heart in only 11 cases. With antibiotic treatment, a lowering of temperature was shown within an average of 10 days of follow up. Two fatalities were reported. CONCLUSION: This study showed that right-sided endocarditis is common in our clinical practice. This infection was prevalent in patients with congenital heart disease or peripartal cardiomyopathy in our context, and the venous route seemed to be the main entry point.
