[Evolution profiles of acute coronary syndromes and GRACE, TIMI and SRI risk scores in Burkina Faso. A monocentric study of 111 patients]. / Profils évolutifs des syndromes coronaires aigus et scores de risque GRACE, TIMI et SRI au Burkina Faso. À propos d'une série monocentrique de 111 patients.

OBJECTIVES: The aims of this study was to assess evolution profile of acute coronary syndrome (ACS) based on risk level by GRACE, TIMI and SRI scores in the cardiology department, Yalgado Ouedraogo university hospital. PATIENTS AND METHODS: This was a prospective study of 111 consecutive patients admitted for ACS (mean age 57.61 years, 77.5% male) between January 1st and 2010 to May 31st 2015 in the department of cardiology. For each patient, risk scores were calculated and they were divided into risk group. Global survival at one month was described by Kaplan Meier method and prognostic factors were analyzed by multivariable Cox regression. RESULTS: The prevalence of ACS was 4.2%. Patients were admitted for ST-elevation ACS and non-ST-elevation ACS in 88.3% and 11.7%, respectively. Nineteen patients (17.1%) were admitted before the 12th hour. Hospital mortality was 8.1% and increased to 16.2% in one month. After risk stratification, one-month survival of patients with high risk, was shorter than patients at low-risk regardless of the score GRACE (log-rank=9.93, P=0.007), TIMI (log-rank=14.91, P=0.001) and SRI (log-rank=10.01, P=0.006). GRACE score (HR=1.01; P=0.002), TIMI (HR=1.33; P=0.01) and SRI (HR=1.02; P=0.01) were major prognostic factors for overall survival. CONCLUSION: ACS remains a serious disease with high morbidity and mortality in the days following the initial accident. These risk scores are applicable tools in Burkina Faso as evidenced statistic C (GRACE=0.75, TIMI=0.78 and SRI=0.74).

[Five years assessment of cardiac stimulation in two public hospitals in Burkina Faso: An experiment of collaboration with two hospitals in Auvergne]. / Bilan de cinq ans de stimulation cardiaque dans deux structures hospitalières publiques du Burkina Faso : expérience d'une collaboration avec deux centres hospitaliers d'Auvergne.

OBJECTIVES: Cardiac stimulation becomes a reality in Burkina Faso. The aim of our study was to evaluate this activity over five years and to appreciate the impact of collaboration with French hospitals of Auvergne area in its development. MATERIALS AND METHODS: Prospective study including consecutively patients who underwent pacemaker implantation since June 2011. Data collected included indications, time to care, type of stimulation, complications, cost of treatment, and education and quality of life of the patient. RESULTS: Sixty-nine patients received definitive pacemaker from June 2011 to June 2016, of whom 45.5% were women. The mean age was 69 years (extremes 35 to 89s). Almost all patients (94%) were symptomatic (54% syncope and 30% dizziness and lipothymias). The main indication for definitive cardiac pacing was complete atrioventricular block of degenerative origin (83%). The mean time between indication and surgery was 8.2 days, and only 4% of patients received temporary stimulation. The lack of financial support was the main reason for the delay in taking charge. During the study period, the two health centers received support in the form of stimulation equipment, a technical platform, and regular training and practical training. This collaboration made it possible to overcome the lack of material, human and financial resources. We recorded as complications a case of case exteriorization, two cases of benign local hematoma and two cases of probe displacement. The quality of life of the patients improved markedly, none of patients undergoing surgery remained symptomatic. CONCLUSION: The organization of cardiac stimulation in Burkina Faso is a reality. Efforts must be made to sustain the activity and strengthen collaboration with hospitals in the north.

[Severe pulmonary embolism and acute lower limb ischemia complicating peripartum cardiomyopathy successfully treated by streptokinase]. / Embolie pulmonaire grave et ischémie aiguë de membre inférieur compliquant une cardiomyopathie du péripartum traitées avec succès par thrombolyse à la streptokinase.

Peripartum cardiomyopathy is a cardiac disease at high thromboembolism potential. The authors report a case of peripartum cardiomyopathy admitted for congestive heart failure. Echocardiography found a dilated cardiomyopathy with severely impaired left ventricular systolic function and biventricular thrombi. During hospitalization his condition was complicated by severe bilateral pulmonary embolism and left lower limb arterial acute thrombosis. The treatment consisted of thrombolysis with streptokinase associated with dobutamine (in addition to the conventional treatment of heart failure and bromocriptine). The outcome was favorable, marked by pulmonary and lower limb arterial unblocking.

Isolated aortic valvular and pulmonary involvement during essential eosinophilia.

Endomyocardial fibrosis is the most classic and the most known complication of prolonged hypereosinophilic syndrome, whatever the cause. In Burkina Faso, this complication is most frequently encountered in idiopathic form of the syndrome. It commonly involves the apex of the ventricles with possible involvement of atrioventricular valves. The clinical picture is that of restrictive cardiomyopathy with poor prognosis. We report the case of a 22-year-old man with atypical cardiac involvement during idiopathic hypereosinophilic syndrome. Echocardiographic examination showed isolated aortic valve involvement. Left and right ventricular function was preserved. The apex of ventricles was free of lesion. Pulmonary CT-scan showed massive bilateral lung involvement. Treatment consisted of strict control of the eosinophilic process and pulmonary management. The patient suddenly died sudden pulmonary distress one month after first being seen.

[Neurological complications of infective endocarditis in Burkina Faso. Clinical features, management and evolutionary profile]. / Les complications neurologiques des endocardites infectieuses au Burkina Faso. Caractéristiques cliniques, prise en charge et profil évolutif.

INTRODUCTION: Neurological complications are the most frequent extracardiac complications of infective endocarditis (IE). This study aimed to describe the epidemiological, clinical and paraclinical aspects, and outcome of neurological complications of infective endocarditis in three hospitals in the city of Ouagadougou in Burkina Faso. PATIENTS AND METHOD: From 1 January 2009 to 31 December 2012, we included all patients suffering from IE and selected those in whom a neurological complication was objectified. Neurological involvement was sought on clinical examination but especially CT brain (ischemic infarcts, hemorrhages, aneurysms and abscesses). Blood cultures were systematic. Echocardiography was done for vegetations and characteristics. RESULTS: Among 63 cases of IE, neurological complications were found in 14 patients (22.2%). The average age of patients with neurological complications was 37.4 ± 5.8 years. The sex ratio was 1.3 for women. Neurological damage consisted of nine cases of stroke (64.3%), three cases of hemorrhagic stroke (21.4%) and two cases of brain abscess (14.3%). Neurological complications had already occurred before hospitalization in 4 cases. Blood cultures were positive in 8 cases. Germs found were predominantly Staphylococcus aureus (5 cases) and Streptococcus a- viridans (2 cases). All cases of S. aureus were complicated by stroke. At echocardiography, vegetation was found in all cases. It was found on the mitral in 7 cases, the aorta in 3 cases, the mitral and aortic in 2 cases and the mitral and tricuspid in 2 cases also. The EI had occurred on a native valve in 11 cases, prosthesis in 4 cases (2 mitral and 2 aortic). The vegetations average diameter was 11.2 ± 2.1 mm (6.4 and 1 7.7 mm). Vegetations were mobile in 12 cases. The treatment consisted of antibiotics adapted to the antibiogram, neurological and cardiovascular monitoring. The evolution was marked by seven deaths (50%), including 5 deaths related to cerebral complication (71.4% of deaths). CONCLUSION: This study shows that neurological complications during infective endocarditis are frequent, dominated by stroke with a high mortality.
