RESUMEN
INTRODUCTION: Acute circulatory failure is a life-threatening emergency whose prognosis depends on early management and aetiological diagnosis. The aim of our study was to assess the epidemiological, aetiological, therapeutic and prognostic aspects of acute circulatory failure in two cardiology departments in Dakar. METHODS: This was a longitudinal, multicentre, descriptive study over a period of six months from October 2014 to March 2015. We included all patients with acute circulatory failure (systolic blood pressure < 90 mmHg, oligoanuria, tachycardia, tachypnoea, onset of altered consciousness) either on admission or during hospitalisation during the study period. A long-term survival survey (six months to one year) was conducted on all included patients. RESULTS: Forty-four patients were enrolled. The average age was 54.9 years, ranging from 20 to 83 years. The gender ratio was 1.1. Acute circulatory failure occurred most often during hospitalisation (63%), with known cardiomyopathy in 47.7% of cases. Consciousness was impaired in 11 patients while oligoanuria was present in 27.3% of cases. Inflammatory syndrome was mostly found in 63.6% of cases and renal insufficiency and acute liver failure were reported in 45.5 and 29.5% of patients, respectively. Left ventricular dysfunction was the most common echocardiographic feature (70%). Acute circulatory failure was cardiogenic in most cases, with a predominance of advanced dilated cardiomyopathy (44.9%). Septic shock was found in 25% of patients, with pulmonary infection as the main location (20%). Nine per cent of patients had hypovolaemic shock. The most used inotropic drug was dobutamine in 79.5% of cases, followed by adrenaline (18.2%) and norepinephrine (4.5%). Intra-hospital mortality rate was high (52.3%) and one-year survival rate was 27.2%. Poor prognostic factors such as advanced age and renal impairment were associated with a higher overall mortality rate of 18 to 90%, with no statistical significance. CONCLUSIONS: Acute circulatory failure is a diagnostic and therapeutic emergency with a high mortality rate.

BACKGROUND: Congenital heart diseases in adults include malformations treated in childhood that decompensate secondarily and those asymptomatic at birth, appear later. This study aims to identify congenital heart diseases in adults in general cardiology department of Senegal and to assess clinical presentations, treatment and outcomes. METHODS: We conducted a cross-sectional and descriptive study based on the records of patients aged at least 16 years and followed for congenital heart disease in the cardiology department of the General Hospital of Grand-Yoff in Dakar between May 2003 and March 2015. Diagnosis of heart disease was based on echocardiography. RESULTS: We have registered 50 dossiers of patients equivalent to a prevalence of 0.75%, with a female predominance (64%). The average age of patients was 36.2±18.4 years (16-79 years), and mean age of diagnosis was 29.76±22.58 years. Dyspnea was the main sign (60%). Main malformations were the atrial septal defect (38%), pulmonary stenosis (14%), the ventricular septal defect (12%) and patent ductus arteriosus (10%). According to the classification of Bethesda, heart disease was simple complexity (42%), intermediate (58%) or severe (10%). The treatment was medical in 43 patients and 7 patients had surgical repair. Main complications were infective endocarditis (10%), atrial fibrillation (12%), heart failure (24%) and pulmonary arterial hypertension (50%). CONCLUSION: Congenital heart diseases in adults seem underestimated in our countries. Surgical repair is rare. It is necessary to ensure a good management of the transition between pediatric and adult age.

The aim of this study was to compare the features of coronary artery disease between diabetic and non-diabetic patients. PATIENTS AND METHODS: A case-control study was carried out from 1 May 2013 to 31 July 2015 in the department of cardiology of Aristide le Dantec university hospital. Forty-five diabetic patients and forty-five non-diabetic patients who underwent coronary angiography and / or angioplasty were included. RESULTS: There was a male predominance with a sex ratio of 1.6 in both groups. The mean age was 62.26 years for diabetics and 59.06 years for non-diabetics (p = 0.6). In diabetics, symptomatology was dominated by silent ischemia (48.9%) versus typical angina pain (68.9%) in non-diabetics. Myocardial infarction was the most common indication of coronary angiography in both groups. Coronary angiography revealed one-vessel disease (46.6% versus 41.7% p = 0.822), double vessel disease (26.7% versus 41.7% p = 0.091) and triple vessel disease (26.7% versus 16.6% p = 0.561). Angioplasty was indicated in 37.8% of diabetics versus 63.9% of non-diabetics. Nine diabetic patients and three non-diabetic patients had an indication of coronary artery bypass grafting. CONCLUSION: Our study confirms the greater frequency of silent ischemia and multiple-vessel disease in diabetics as well as a more frequent indication of coronary artery bypass grafting in these patients.
L'objectif de cette étude était de comparer les aspects de la maladie coronaire entre les patients diabétiques et non diabétiques. PATIENTS ET MÉTHODES: Une étude cas-témoins a été réalisée du 1er mai 2013 au 31 juillet 2015 au service de cardiologie du CHU Aristide le Dantec. Quarante cinq patients diabétiques et 45 patients non diabétiques ayant bénéficié d'une coronarographie et/ou d'une angioplastie avaient été inclus. RÉSULTATS: Nous avions retrouvé une prédominance masculine avec un sex ratio de 1,6 dans les deux groupes. L'âge moyen était de 62,26 ans pour les diabétiques et de 59,06 ans pour les non diabétiques (p=0,6). Chez les diabétiques, la symptomatologie était dominée par l'ischémie silencieuse (48,9%) et la douleur angineuse typique (68,9%) chez les non diabétiques. L'infarctus du myocarde était l'indication de la coronarographie la plus fréquente dans les deux groupes. La coronarographie retrouvait respectivement chez les diabétiques et non diabétiques une atteinte mono-tronculaire (46,6% versus 41,7% p=0,822), une atteinte bi-tronculaire (26,7% versus 41,7% p=0,091) et une atteinte tri-tronculaire (26.7% versus 16,6 % p=0,561). Une angioplastie avait été indiquée chez (37,8%) des diabétiques et (63,9%) des non diabétiques. Neuf patients diabétiques et trois patients non diabétiques avaient eu une indication de pontage coronaire. CONCLUSION: Notre étude confirme une plus grande fréquence de l'ischémie silencieuse et de l'atteinte multi tronculaire chez les diabétiques ainsi qu'une indication plus fréquente de pontage aorto coronaire.
RESUMEN
Systemic lupus erythematosus is a non-specific inflammatory disorder of an organ of unknown cause and autoimmune origin. Visceral injuries, including those cardiovascular, determine the prognosis of this disease primarily affecting women. The objectives of this study were to determine the frequency and describe the cardiovascular manifestations in systemic lupus erythematosus in a lupus population of the Dakar region. This is a multicenter prospective study descriptive and analytical conducted in the region of Dakar (Senegal) from 14 February 2011 to 2 July 2012. Patients were either hospitalized or monitored as outpatients. Included were all patients with lupus and meeting at least four criteria of the American College of Rheumatology of lupus disease classification 1997. All patients underwent physical examination, an electrocardiogram and an echocardiogram looking for cardiovascular damage. The collected data were entered into the Epi Info version 3.5.1 and processed with SPSS 16.0 software. Quantitative variables are described in the median and the qualitative workforce, percentage and frequency. We have included 50 patients. The average age of the population was 36.18 years. A female predominance is noted with a sex ratio man/woman of 0.09. Cardiovascular functional symptoms were dominated by dyspnea stage II to IV NYHA (26%) and palpitations (22%). The physical signs we have found were mainly tachycardia (40%), spontaneous turgor of the jugular veins (29%), a muffling of the heart sounds (29%) and a infandibulopulmonairy shock (18%). The frequency of cardiovascular events was 46%. Electrical cardiac events were dominated by sinus tachycardia (40%) of repolarization disorders (16.3%) type of ischemia, injury, ischemia injury, necrosis and hypertrophy with 18% atrial and left ventricular hypertrophy each. Furthermore, one case of BAV first degree at 280 ms was recorded. We found 19 cases of pericarditis including 2 tamponade, 3 cases of dilated cardiomyopathy hyperkinesias with impaired ejection fraction less than 35% and 8 patients with mild PAH important. In systemic lupus erythematosus, cardiovascular events are worrying and may remain asymptomatic for awhile. Their research must be systematic in order to treat early.

Congenital heart diseases are one of the major cardiovascular diseases in developing countries. Most prevalence studies were based on clinical examination of children with echocardiographic confirmation of suspected cases and underestimate its prevalence. The objective of this study was to investigate the prevalence of congenital heart disease in "daara" (Koranic schools) in the city of Dakar and its suburbs on the basis of clinical examination and Doppler echocardiography in school children. This cross-sectional survey was carried out from 9(th) August to 24(th) December 2011, and included a population of 2019 school children aged 5 to 18 years in 16 selected "daaras" under the Academic Inspectorate of Dakar and its suburbs. Anamnestic, clinical and echocardiographic data were recorded in a validated questionnaire. A p < 0.05 was considered to be statistically significant in bivariate analysis. 2 019 school children were included out of which 60.1% were male (sex-ratio: 0.66). The average age was 9.7 years (± 3.3 years). 18 cases of congenital heart diseases were detected being a prevalence of 8.9 per 1 000 (95 % CI: 1.8 to 7.9). This included 6 cases of inter-atrial septal aneurysm, 5 cases of peri-membranous ventricular septal defects, 4 cases of patent ductusarteriosus and 3 cases of tetralogy of Fallot. Factors correlated with the presence of congenital heart disease were ageless than 8 (p <0.001) and residence in the suburbs of Dakar (p <0.001). We also detected 10 cases of rheumatic valvular disease, a prevalence of 4.9 per 1 000 (95% CI: 2.4 to 9.1). Our study shows a high prevalence of congenital heart diseases, which is almost identical to the WHO estimates and that ultrasound screening is more sensitive than clinical screening. Reducing the prevalence of these diseases requires implementation of appropriate policies, focusing on awareness and early detection.
