Acute circulatory failure in two cardiology departments in Dakar: 44 cases.

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.

[Ambulatory Blood Pressure Measurement's Reults And Indications At Cadiology Department At Hôpital Aristide Le Dantec]. / Indications Et Resultats De La Mesure Ambulatoire De Pression Arterielle Au Service De Cardiologie De L'Hopital Aristide Le Dantec.

High blood pressure (HTA) is a public health problem. It affects more than one billion people around the world, more than a quarter of the world's population. In recent years the ABPM (Ambulatory Blood Pressure Measurement) has become a valuable and widely used tool for the diagnosis and management of hypertension. The aims of this study were to determine the indications of MAPA to the cardiology department of Aristide le Dantec Hospital; to determine the results and to evaluate the blood pressure profile of our patients. METHODS: We carried out a retrospective study, over 37 months from December 2010 to December 2013 covering all the results of the ABPMs recorded during this period. Was included any patient over 18 years of age with an ABPM. All ABPMs with less than 50 good measures per 24 hours were not included. RESULTS: A total of 204 MAPA results were included of a total of 307. The mean age was 49.6 ± 11.5 years with extremes of 25 years and 78 years. The sex ratio was 1.5 in favour of women. Indications were dominated by labile HTA (34.8%); masked HTA (27.9%) and suspicious of the white coat effect (12.3%). The analysis of the results showed that MAPA was normal in 49.5%. The white coat effect was found in 32% (65 patients) of ABPM. In patients with abnormal ABPM, permanent systolic-diastolic hypertension predominated (57%). HTA masked was noted in 25.7% of our patients and HTA white coat was found in 3.8% of cases. In the hypertensive patients treated, MAPA revealed a poor blood pressure balance in 42.1%. Among the HTA prognostic factors we noted32.4% of patients were "Non Dippers", a pulse pressure greater than or equal to 60 mmHg in 59%. CONCLUSION: The use of this exploration is an important aid to practitioners in the diagnostic, therapeutic and prognosis phase of the management of hypertension. It should become more important as it provides better information on the blood pressure profile for the patients.

INTRODUCTION: L'hypertension artérielle(HTA) représente un problème de santé publique. Elle concerne plus d'un milliard d'individus à travers le monde, soit plus du quart de la population mondiale. Ces dernières années la MAPA (mesure ambulatoire de la pression artérielle) est devenue un outil précieux et largement utilisé pour le diagnostic et la prise en charge de l'HTA. Les objectifs de ce travail étaient de déterminer les indications de la MAPA au service de cardiologie de l'hôpital Aristide le Dantec ; d'en déterminer les résultats et d'évaluer le profil tensionnel de nos patients. MÉTHODES: Nous avons réalisé une étude rétrospective, sur 37 mois allant de Décembre 2010 à Décembre 2013 portant sur l'ensemble des résultats des MAPA enregistrées durant cette période. Était inclus tout patient âgé de plus de 18 ans chez qui une MAPA a été enregistré Toutes les MAPA ayant moins de 50 bonnes mesures par 24 heures n'ont pas été inclus. RÉSULTATS: Au total 204 résultats de MAPA ont été inclus sur un total de 307. L'âge moyen était de 49,6 ± 11,5 ans avec des extrêmes de 25 ans et 78 ans. Le sex ratio était de 1,5 en faveur des femmes. Les indications étaient dominées par l'HTA labile (34,8%) ; l'HTA masquée (27,9%) et la recherche de l'effet blouse blanche (12,3%). L'analyse des résultats avait montré que la MAPA était normale dans 49,5% des cas. L'effet blouse blanche était retrouvé dans 32% (65 patients) des MAPA réalisées à visée diagnostique. Chez les patients dont les résultats étaient anormaux l'HTA systolo-diastolique permanente prédominait (57%) avec une différence significative (p=0,003). L'HTA masquée étaient notée chez 25,7% de nos patients et l'HTA blouse blanche était retrouvée dans 3,8% des cas. Chez les hypertendus traités, la MAPA avait révélé un mauvais équilibre tensionnel dans 42.1% des cas et cela au dépens de la systolique avec une différence significative (p=0,02). Parmi les facteurs pronostiques on retrouvait 32,4% de patients « Non Dippers ¼, une pression pulsée supérieure ou égale à 60 mm Hg dans 59%. Le caractère adrénergique était retrouvé chez 65,7% de nos patients. CONCLUSION: L'utilisation de cette exploration constitue une aide importante aux praticiens à la phase diagnostique, thérapeutique, et pronostique de la prise en charge de l'HTA. Elle devrait occuper de plus en plus de place car elle donne de meilleurs renseignements sur le profil tensionnel dans l'environnement quotidien habituel du patient.

[Comparative Study Of Coronary Artery Disease In Diabetics And Non-Diabetics In The Department Of Cardiology Of Aristide Le Dantec University Hospital]. / Etude Comparative De La Maladie Coronaire Chez Les Diabétiques Et Non Diabétiques Au Service De Cardiologie Du CHU Aristide Le Dantec.

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.

[Cardiovascular manifestations in systemic lupus erythematosus in Dakar: Descriptive study about 50 cases]. / Les manifestations cardio-vasculaires au cours du lupus érythémateux systémique à Dakar : étude descriptive à propos de 50 cas.

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.

[Prevalence of dyslipidemia in the rural population of Gueoul (Senegal)]. / Prévalence de la dyslipidémie dans la population rurale de Guéoul (Sénégal).

INTRODUCTION: The cardiovascular risk factors are clearly increasing in developing countries. Among these factors, dyslipidemia is often found, this due to the change in behavioral and dietary habits (OMS, 2006). Dyslipidemia is a "primary or secondary pathological changes in serum lipids". It is a chronic and metabolic abnormality, characterized by persistently elevated TG, LDL-c, and a decrease in HDL (Attias et al., 2013-2014). The objective of this study is to determine the prevalence of dyslipidemia, and give the lipid profile of the population in Gueoul. PATIENTS AND METHODS: We performed a comprehensive observational study, cross-sectional descriptive on Senegalese aged 35 or over, living in Gueoul for at least 6 months. Lipid profile (total cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol) was systematically after 12hours of fasting. RESULTS: Dyslipidemia was found in 61.3 % of cases with 50 % pure hypercholesterolemia (n=705). Only 20 subjects (2.3 %) knew they had dyslipidemia. The detection rate was 59.8 % (n=844). The type most represented was hypoHDLemia (45.6 %) followed by hyperLDLemia (28.8 %). Triglycerides were increased in only 2.8 % of cases. CONCLUSION: The prevalence of dyslipidemia is very high in our regions. It is often associated with female gender, hypertension, diabetes, and obesity. Its main causes are physical inactivity, change in lifestyle and eating habits. It is often misunderstood and its management is limited in most cases to low-calorie diet.

[Prevalence of congenital heart diseases in Koranic schools (daara) in Dakar: a cross-sectional study based on clinical and echocardiographic screening in 2019 school children]. / Prévalence des cardiopathies congénitales en milieu scolaire coranique (daara) à Dakar : étude transversale basée sur le dépistage clinique et échographique de 2019 élèves.

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.

[Pseudoaneurysm of the left ventricle in young patients: A propos of three cases]. / Faux anévrisme du ventricule gauche du sujet jeune : à propos de trois cas.

Pseudoaneurysm of the left ventricle is a rare late complication of myocardial infarction. So-called non-coronary forms have been described in young people. In this context, we report three cases. Mr. M.B., aged 20, consulted for chest pain associated with palpitations. Cardiovascular examination found a pulsatile, expanding precordial bulging and a mesocardiac systolo-diastolic murmur. We noted a sinus rhythm with ventricular extrasystoles on ECG. The chest radiograph showed cardiomegaly and aneurysmal deformation of the left lower heart border. Doppler echocardiography showed a large left ventricular apical pseudoaneurysm. Mrs. O.B., aged 23, was admitted for biventricular heart failure and in whom the examination found a systolic murmur in the apical area. ECG showed a regular sinus tachycardia, left atrial and ventricular hypertrophy. The chest radiograph showed cardiomegaly and aneurysmal deformation of left middle and lower heart borders. Doppler echocardiography showed a large left ventricular apical pseudoaneurysm. Mr. I.S., aged 24, admitted for the management of congestive heart failure. The patient had non-specific laboratory inflammatory signs, a sinus tachycardia and extrasystoles on the ECG. Chest radiography showed a discontinuation at the posterior arch of the sixth rib, a cardiomegaly and a neurismal dilatation of the left lower heart border. Doppler echocardiography showed a large apical pseudoaneurysm of the left ventricle.

Efficacy of newer versus older antihypertensive drugs in black patients living in sub-Saharan Africa.

To address the epidemic of hypertension in blacks born and living in sub-Saharan Africa, we compared in a randomised clinical trial (NCT01030458) single-pill combinations of old and new antihypertensive drugs in patients (30-69 years) with uncomplicated hypertension (140-179/90-109 mm Hg). After ≥4 weeks off treatment, 183 of 294 screened patients were assigned to once daily bisoprolol/hydrochlorothiazide 5/6.25 mg (n=89; R) or amlodipine/valsartan 5/160 mg (n=94; E) and followed up for 6 months. To control blood pressure (<140/<90 mm Hg), bisoprolol and amlodipine could be doubled (10 mg per day) and α-methyldopa (0.5-2 g per day) added. Sitting blood pressure fell by 19.5/12.0 mm Hg in R patients and by 24.8/13.2 mm Hg in E patients and heart rate decreased by 9.7 beats per minute in R patients with no change in E patients (-0.2 beats per minute). The between-group differences (R minus E) were 5.2 mm Hg (P<0.0001) systolic, 1.3 mm Hg (P=0.12) diastolic, and 9.6 beats per minute (P<0.0001). In 57 R and 67 E patients with data available at all visits, these estimates were 5.5 mm Hg (P<0.0001) systolic, 1.8 mm Hg (P=0.07) diastolic and 9.8 beats per minute (P<0.0001). In R compared with E patients, 45 vs 37% (P=0.13) proceeded to the higher dose of randomised treatment and 33 vs 9% (P<0.0001) had α-methyldopa added. There were no between-group differences in symptoms except for ankle oedema in E patients (P=0.012). In conclusion, new compared with old drugs lowered systolic blood pressure more and therefore controlled hypertension better in native African black patients.

[Venous thrombosis and bilateral arterial occlusion of lower limb revealing HIV infection]. / Thrombose veineuse et occlusion artérielle bilatérale des membres inférieurs révélant une infection par le VIH.

Human immunodeficiency virus (HIV) infection can cause vascular complications. This is most often of lower limb venous thrombosis. Rare cases of limb ischemia indicative of HIV infection have been described.We report a case of venous thrombosis of the left lower limb and bilateral lower arterial ischemia revealing an HIV infection in a patient of 44 years. The CD4 count was 195/mm(3). Investigations on coagulation were not realized. The patient was amputated both his legs.

[Aneurysmal dilatation of pulmonary artery and its branches on mitral stenosis: a case report]. / Dilatation anévrismale de l'artère pulmonaire et de ses branches sur sténose mitrale à propos d'un cas.

Pulmonary arteries aneurysms are rare and the rarely described bilateral aneurysms. A 45-year-old patient carrier of mitral stenosis was admitted for dyspnoea class III of the NYHA, chest pain and a not infectious cough. The clinical examination found semiology of mitral stenosis, tricuspid incapacity and pulmonary arterial hypertension. The electrocardiogram showed atrial fibrillation and right ventricle hypertrophy. Chest X-ray found a cardiomegaly, an aspect of double outline of the inferior right bow, a prominent aspect of the left average bow reminding an aneurysm of the left pulmonary artery. The echocardiography Doppler found a pure tight mitral stenosis (mitral surface=0.6 cm(2)), a dilation of the trunk of the pulmonary artery (diameter=74 mm) and of its branches (diameter of the right pulmonary artery=28 mm, diameter of the left pulmonary artery=36 mm) seat of a spontaneous contrast. The left atrium and right cardiac cavities were also dilated. There was an important tricuspid incapacity with a major pulmonary hypertension (systolic pulmonary arterial=109 mmHg). The thoracic angioscan showed a pseudoaneurysm of the trunk of pulmonary artery and its branches to their distal parts. Under diuretic, anticoagulating and analgesic treatment the clinical signs improved however the spontaneous contrast persisted. The patient was rejected by the surgery for exceeded clinical board. She is at present followed in our service for 5 months.

Infections secondary to pacemaker implantation: a synopsis of six cases.

INTRODUCTION: Permanent cardiac pacing is a technique whose indications have increased in the last 20 years. As with any foreign body, pacemaker implantation is associated with the risk of infection. The objective of this study was to describe the clinical, paraclinical and treatment options of infections secondary to pacemaker implantation at the Cardiology Department of the Aristide le Dantec Teaching Hospital (CHU Aristide le Dantec) in Dakar, Senegal. METHODS: We conducted a retrospective study over a period of three years (from January 2005 to December 2007) during which pacemaker implantation was carried out in 107 patients. All patients with local and/or systemic signs of infection were included in our study. RESULTS: The prevalence of infection in patients with pacemakers was 5.6% in our series and infection occurred in three women and three men, with a mean age of 66.2 years (range 23-83). The delay time for the onset of clinical signs of infection was 6.6 months, with a range of eight days to 12 months. The clinical signs were externalisation of the pacemaker with suppuration (five cases), fever (one case) and inflammatory signs (one case). Factors favouring the occurrence of infection were co-morbidity (four cases), pre-operative length of stay (average eight days), use of temporary cardiac pacing (three cases), the number of people in the theatre (average 4.5), postoperative haematoma (one case) and repeating the surgical procedure (three cases). Staphylococcus epidermidis (two cases), Staphylococcus aureus (two cases) and Klebsiella pneumonia (one case) were the organisms isolated at the local site. Transthoracic echocardiography showed no objective signs of endocarditis. The treatment was antibiotic therapy for an average duration of 50.4 days after debridement of the infected site (six cases). We noted four recurrences at six months and one death from sepsis at 12 months. CONCLUSION: Infections secondary to pacemaker implantation are rare but serious. Their management is difficult and requires the removal of the implanted material, hence the importance of prevention of infection, or the removal and re-implantation of the pacemaker at another site in cases of infection. This is particularly important in our region where pacemakers are very expensive.

Vascular complications of infective endocarditis.

UNLABELLED: The complications of infective endocarditis (IE) are frequent and severe. Our objectives were to analyze the clinical, paraclinical, and prognostic features of IE vascular complications observed in two cardiology units, in Dakar. PATIENTS AND METHODS: We retrospectively studied 90 patients presenting with of IE, hospitalized between January 2005 and February 2011. The diagnostic criteria for IE were modified Duke University criteria. We selected in our study population, patients with vascular complications. RESULTS: Seventeen patients (18.8%) presented with one or more vascular complications of IE: eight male and nine female patients, with a mean age of 28 years. Infective endocarditis occurred on an abnormal valve in 15 cases. We identified 22 vascular lesions: ten neurological complications, seven arterial complications in the limbs, two myocardial infarctions, two cases of pulmonary embolism, and one splenic infarction. The vascular complication revealed an IE in seven cases. The vascular complication occurred during antibiotic treatment, in 15 cases including seven cases before the 14th day, nine of the 17 patients died. Death was related to vascular complications in six cases, in one case it was related to septic shock. CONCLUSION: Vascular complications of IE are frequent, the most common are neurological. Their prevention requires early and adequate management of IE.

[Aortopulmonary infectious endocarditis with fatal evolution: a case report]. / Endocardite infectieuse aortopulmonaire d'évolution fatale : à propos d'un cas.

We report the case of an aortic and pulmonary infective endocarditis in a 25-year-old patient originating from Guinea Conakry. The patient did not have any particular cardiovascular antecedent. He is allowed in a table of total heart failure and fever. The transthoracic echocardiography found vegetations on the level of sigmoid aortic and pulmonary ones. A probabilistic bi-antibiotherapy was instituted while waiting for the results of hemocultures. The patient was apyretic after one week, with regression of inflammatory biological syndrome. However, he was deceased after 20 days in a table of heart failure. The necropsy found vegetations on the level of sigmoid aortic and pulmonary ones, which were perforated, a right lung oedema and a cardiac liver.

[Role of thrombolysis in massive pulmonary embolism]. / Place de la thrombolyse dans l'embolie pulmonaire grave.

AIMS: Massive pulmonary embolism is a life threatening pathology with a high mortality over 20%. Thrombolysis is one of therapy ways that leads to a lower rate of death. The aim of the study is to show interest, limits and complications of thrombolytic therapy in massive pulmonary embolism. PATIENTS AND METHODS: This descriptive study presents 8 cases of pulmonary embolism admitted to the Cardiology Division of Grand-Yoff from March 2003 to March 2006. All cases confirmed by Tomodensitometry (TDM) with massive pulmonary embolism were included in this study. RESULTS: We used thrombolytic only in 8 cases of massive pulmonary embolism about 32. In-hospital prevalence was 25%. The average age was 49.8 ± 19.1 (from 15 to 72) and sex-ratio 0.33. Seven patients had a moderate clinical probability Well's score and one of them 1 had a high clinical probability. The clinical signs were: cardio-vascular collapse (7 cases), syncope (1) and cardio-vascular arrest. The electrocardiogram showed a sub-epicardial ischemia (4 cases), a right bundle branch block and a Mac Ginn White's sign. Two patients had a right-basal opacification at the chest X ray. The echocardiography found 5 cases of right ventricular dilatation, 1 case of paradoxal septum, 1 case of multiple thrombi in the right ventricule. The TDM confirmed diagnosis with 3 cases of bilateral pulmonary embolism, 1 case of pulmonary aneurysm. The treatment used thrombolytic : 1,500,000 IU of streptokinase, sympathomimetic drugs, anticoagulation with heparins and vitamin K antagonists.

[Epidemiological, clinical and ultrasonographic aspects of right-sided infective endocarditis in Senegal: 6 cases]. / Aspects epidémiologiques, cliniques et echographiques des endocardites infectieuses du coeur droit au Sénégal: 6 observations.

Right-sided infective endocarditis accounts for 5 to 10% of endocarditic involvement and usually affects the tricuspid valve. The purpose of this report is to describe epidemiological, clinical and echocardiographical aspects of 6 cases of right-sided infective endocarditis observed in the Cardiology Department of Aristide Le Dantec Hospital in Dakar, Senegal from December 2007 to February 2010. Diagnosis was based on Duke's modified criteria. There were 3 men and 3 women with a mean age of 28.2 years (range: 20 and 43). Five of the 6 patients presented tricuspid endocarditis including one case associated with pulmonary endocarditis. In another case, pulmonary endocarditis was associated with aortic endocarditis. Infective endocarditis was acute in three cases and primary in four. One case of infective endocarditis was observed in a tetralogy of Fallot. Fever was present in 4 cases with an mean temperature of 38.4 degrees C (range, 37.2 to 40 degrees C) and heart failure was present in 5 cases. In 2 patients, blood cultures were positive for Staphylococcus aureus. All patients had leucocytosis with a neutrophilic predominance. Doppler echocardiography depicted vegetations in all cases. Contributing factors included congenital heart disease in 1 case, insertion of a venous catheter in 2 and dental infection in 2. No patient was addicted to intravenous drugs or infected by HIV. Outcomes included one in-hospital death with signs of refractory heart failure. Right-sided endocarditis is often primary and is dominated by the tricuspid involvement. It affects both sexes. Contributing factors include venous catheterization during the postpartum period and dental infection. Prevention requires strict asepsis during venous catheter insertion, treatment of dental infections and improved management of congenital heart disease.

Place de la thrombolyse dans l'embolie pulmonaire grave

But : l'embolie pulmonaire grave est une pathologie grevée d'une lourde mortalité supérieure à 20%.La thrombolyse fait parti des moyens thérapeutiques qui permettent de réduire cette mortalité. L'objectif de ce travail était de déterminer l'intérêt, les limites et les complications de la thrombolyse dans l'embolie pulmonaire grave. Malades et Méthode : il s'agit d'une étude descriptive portant sur huit cas d'embolie pulmonaire grave admis au Service de Cardiologie de l'Hôpital Général de Grand Yoff de Mars 2003 à Mars 2006. Toutes les embolies pulmonaires graves, confirmées à l'angio-scanner thoracique et ayant bénéficiées d'une thrombolyse, étaient incluses. Résultats : huit cas d'embolie pulmonaire grave étaient sur 32 embolies pulmonaires reçues durant cette période, soit une prévalence hospitalière de 25%. L'âge moyen était de 49,9 ± 19,1 ans (extrêmes de 15 et 72 ans) avec une prédominance féminine (sex-ratio de 0,33). Sept patients avaient un score de probabilité clinique de Wells d'embolie pulmonaire moyenne et un malade avait une probabilité clinique forte. Les signes de gravité étaient le collapsus cardio-vasculaire (7 cas), la syncope et l'arrêt cardiaque respectivement dans 1 cas. L'électrocardiogramme inscrivait 4 cas d'ischémie sous épicardique, un bloc de branche droit et un signe de Mac Ginn White (aspect S1Q3T3) respectivement dans 3 cas. Deux patients présentaient une opacité basale droite à la radiographie thoracique de face. L'échocardiographie Doppler notait une dilatation du ventricule droit (5 cas), un septum paradoxal et des thrombi multiples dans le ventricule droit respectivement dans 1 cas.L'angio-scanner thoracique mettait en évidence une embolie massive constante avec dans trois cas une embolie bilatérale et dans un cas un anévrysme des artères pulmonaires. Nos patients avaient bénéficié d'une thrombolyse à la Stréptokinase en plus d'une expansion volumique, d'amines sympathomimétiques et d'une anticoagulation

[Evolution and thromboembolic complications of the idiopathic peripartal cardiomyopathy at Dakar University Hospital: forward-looking study about 33 cases]. / Évolution et complications thromboemboliques de la myocardiopathie idiopathique du péripartum au CHU de Dakar: étude prospective à propos de 33 cas.

UNLABELLED: The aims of this work are to study the nursery futures during idiopathic myocardiopathy of peripartum (IMPP), to measure the prevalence of thromboses and spontaneous contrast during the IMPP and to determine their evolution. METHODOLOGY: It is about a longitudinal exploratory study carried out with the Aristide-Le-Dantec teaching hospital of Dakar, beginning January 2001 to November 2004, having included 33 patients. RESULTS: The average age of the patients was 26 years; the average pregnancy was of 3.39 gestures. The signs of cardiac insufficiency were constant and four patients (12%) had presented an ischemic cerebral vascular accident. We had raised an auricular case of fibrillation and tachycardia atrial multifocal. The transthoracic echography (ETT) noted an aspect of hypokinetic myocardiopathy dilated with deterioration of the systolic function of the left ventricle, a thrombus in ten patients (30.3%) and a spontaneous contrast in two cases (6%). The transoesophageal echocardiography (ETO) was superposable with the ETT with regard to dimensions of the cardiac cavities and the presence of thrombus but its sensitivity was higher (100% against 66%) with regard to the detection of contrasts spontaneous. All the patients had the treatment of a congestive heart failure associated to an anticoagulant treatment. The evolution was marked by an improvement of the heart failure. The thrombus and spontaneous contrast had disappeared in all the patients. The absence of anaemia and the presence of spontaneous contrast (p=0.003) were correlated with the presence of thrombosis (p=0.05). CONCLUSION: The idiopathic myocardiopathy of the peripartum is a relatively frequent affection in zone Soudano-Sahelian. Occurrence of thromboses is frequent at the time of this affection. Our study confirms the superiority of the echocardiography transoesophageal in the detection of intracardiac spontaneous contrast. The evolution can be favourable subject to a rigorous care and a regular surveillance.

[Pulmonary embolism: autopsy study of 73 cases in Senegal]. / L'embolie pulmonaire: étude nécropsique à propos de 73 cas.

INTRODUCTION: The Pulmonary emblism is a vascular disease which is characterized by the more or less complete obstruction of one or several pulmonary arteritis and/or their branches by an embol. Very polymorphic affection, mortal in the massiv form, it has in the average forms of the atypical or misleading aspects which make its clinical diagnosis difficult. The diagnostic strategy of the pulmonary embolism remains incompletely solved. The objectives of this work are: --to evaluate the prevalence with the autopsy of the pulmonary embolism and its distribution according to the age, --to appreciate the correlation enters the ante and the post-mortems diagnoses. PATIENTS AND METHODS: It is about a retrospective study, over 10 years period, having inclued the files of all the patients died in the various services of medicine or surgery of the university hospital of Aristide Le Dantec but also those transferred from outside of the hospital and at which the pulmonary diagnosis post-mortem of embolism was retained. RESULTS: Sixty thirteen (73) cases of pulmonary embolism had been found during autopsies during the period of study (10 ans), that is to say a prevalence of 1.9%. The average was 35 years. The most representative age bracket was that ranging beetwin 21 and 30 years is 36% of the studied population. On the 73 indexed patients, 30 (41%) were transferred from outside of the hospital and 43 (59%) came from the servicies of medecine and surgery with a prevalance of the service of cardiology (26%). The correlation beetween ante-mortems diagnosis and the anatomical result was 11% for the whole of the patients incleded in the study. However, it was 42% for the sub-grup of patients comming from the service of cardiology. CONCLUSION: The prevalence with the autopsy of pulmonary embolism is weak. The clinical diagnosis of this affection is difficult even in a specilised service with a high rate of negatif forgeries. This pathology is very under- evaluated even in these services.

[Syndrome of "Coup de fouet". A case description and literature review]. / Syndrome du "Coup de Fouet" syndrome d'un cas et revue de la litterature.

The authors bring back the observation of a 48-year-old woman having induced a big painful left calf. The dread os a thrombophlebitis drew away the strarting of an anticoagulative treatment. This treatment was later supended in front of the putting in an a bvious place in echo-Doppler of a haematoma of the calf linked to a normal side of venous fluxes. This table made recall a syndrome of "coup de fouet". It is about a desease characterised by the unpromted rupture of a deep vein of the calf accomplishing a haematoma. It happens in repose or in step as at our patient. It posed a problem of differential diagnosis with a thrombophlebitis of lower limb. Evolution was favourable under treatment linking pause, an anti inflammatory and the haematoma paracentesis under echographique guidance .

[Active rheumatic heart disease: findings from an 17-case series in the University Hospital Center of Dakar, Senegal]. / Cardiopathies rhumatismales evolutives a propos de 17 cas colligés au CHU de Dakar.

This report is based on retrospective review of the charts of 18 patients with pre-existing active rheumatic heart disease compiled over a period of two years (January 2000 to December 2001). The purpose of this study was to determine the incidence of acute degenerative joint disease, to describe the clinical features and natural course of the disease, and to highlight the main points in the fight against degenerative joint disease and rheumatic heart disease. The prevalence of active rheumatic disease was 3.7%. Mean patient age was 15.5 years (range: 8 to 25 years). Female sex was predominant with 13 girls and 4 boys (sex ratio: 3.25). The most common clinical symptoms were migratory polyarthritis involving large joints in 14 cases (82.3%) and left heart insufficiency in 13 (76.4%). Additional clinical findings included oscillating fever in 8 cases (47.05%), tooth decay in 11 (73.3%), and poor buccodental hygiene in 14 (93.3%). Blood tests to evaluate inflammation demonstrated high values in all patients with mean ASLO titer of 950 UI/l, mean serum fibrin level of 7.8 g/l, and mean C-reactive protein level of 28.5 mg/l. The erythrocyte sedimentation rate was high in 15 cases (88.2%). In addition to showing heart valve disease, electrocardiography demonstrated first-degree atrioventricular block in 1 case. Chest x-ray revealed cardiomegaly in 15 cases (88.2%). Doppler ultrasonography of the heart showed isolated rheumatoid disease in 11 cases (64.7%). All patients responded favourably to treatment with corticosteroids and penicillin. The incidence of recurrence of active disease was high (70.5%) thus supporting use of high loading doses. Rheumatic heart disease is a public health problem in Africa and requires appropriate preventive measures.
