Background: Cardiovascular Disease (CVD) has become the largest and most common cause of Non-Communicable Diseases (NCD) related deaths worldwide, accounting for more than 50%. In Senegal, a few studies done on the topic showed a low prevalence of acute coronary syndrome in hospital settings. In the city of Saint-Louis in Northern Senegal, there is little epidemiological data on Acute Coronary Syndrome (ACS) and no study specifically concerned with ST-segment Elevation Myocardial Infarction (STEMI) has been carried out to date. With this in mind, we conducted a study that focused on the analysis of STEMI patients hospitalized in the Cardiology Department of the Regional Hospital of Saint-Louis. The aim of our study was to collect and analyze the epidemiological aspect of STEMI. Results: There were 39 cases of STEMI, (i.e. 82.29% of ACS), giving a hospital prevalence of 8.21%. There was a slight male predominance with a male to female ratio of 1.05. The average age of our patients was 62.93 years ranging from 38 to 90 years. The average time between the onset of pain and arrival at the hospital was 50 hours, ranging from 1 hour to 720 hours. Patients received within the first 12 hours made up 66% (n = 26) of our population, among them, 80.76% (n = 21) (i.e. 53.84% of STEMIs) were able to benefit from thrombolysis. All thrombolysis was performed with Streptokinase. The mean time to thrombolysis was 6 hours ranging from 1 hour and 45 minutes to 11 hours. Arterial hypertension was the most frequent cardiovascular risk factor in our popular with a 43.6% prevalence, followed by diabetes (33.33%), then active smoking (23%).

Introduction: Infectious endocarditis is a transplant of microorganisms in healthy endocardium, in injured endocardium or intracardiac material. The modes of revelation can be multiple and varied, the skin manifestations of an infectious although classical endocarditis, are rare. Observation: This was a young 20-year-old patient, admitted in our cardiac unit for the exploration of a cardiac murmur in a context of long-term fever evolving for nearly 3 weeks associated with a skin rash. The examination found fever at 39°C and tachycardia at 115 beats/min. The cardiac auscultation revealed tachycardia with a systolic breath apexian mitral insufficiency. The skin examination revealed Osler’s nodules, an erythema of Janeway on the soles of the feet and on the palms of the hands. In biology, there was a non-specific biological inflammatory syndrome. Blood cultures from three series of samples did not isolate a germ. The transthoracic echography showed large vegetations in the anterior and posterior leaflets of mitral valve associated with severe mitral regurgitation. In this context, the diagnosis of mitral endocarditis is retained according to the Duke criteria. A double intravenous antibiotic therapy based on ceftriaxone and gentamycin was administrated. The evolution was favorable with stable apyrexia, disappearance of skin signs, regression of non-specific biological inflammatory syndrome. A replacement surgery of mitral valve was proposed. Conclusion: Infectious endocarditis is a disease with multiple and varied modes of revelation. Although skin manifestations are rare, they are still a determining factor in the diagnosis of infectious endocarditis.
