[The contribution of systematic implementation of cardiovascular explorations for the detection of cardiac sources of embolism in patients with stroke: About 230 patients]. / L'apport des explorations cardiovasculaires réalisées de manière systématique lors du bilan étiologique d'un AVC ischémique constitué (À propos de 230 cas).

OBJECTIVES: Ischemic stroke are estimated at 80% of all strokes. Embolism of cardiac origin accounts for around 20% of them. The aim of our study is to report the contribution of cardiovascular investigations performed as a routine during the evaluation of patients with ischemic stroke. PATIENTS AND METHODS: This is a retrospective study of ischemic stroke cases collated in Cardiology department of the military hospital of Marrakech between January 2010 and December 2014. All our patients have systematically ECG, transthoracic echocardiography and Echo-Doppler ultrasound of the neck vessels while the transesophageal (TEE) echocardiography and Holter ECG was performed in some indications. RESULTS: Two hundred and thirty patients were collected. The average age of patients was 66.3±12.5years with a male predominance in 64.2%. Eighty-five percent of patients had at least three cardiovascular risk factors. Hypertension (60.8%), diabetics (41.7%) and tobacco (33.3%). Cardiovascular history was noted in 30% of cases with 10% of dilated cardiomyopathy and 9.2% of ischemic stroke. Cardiovascular explorations led to the diagnosis of heart disease embolism in 32% and atherosclerosis of the neck vessels in 16%. The TEE performed in 8% of cases showed an emboligenic cause in 42% of them. CONCLUSION: Cardiovascular explorations remain indispensable in the workup of all ischemic strokes even if their therapeutic effect is modest. The lacunar infarct out first at 34% followed by 32% of cardio embolic causes and atheroma of the neck vessels in approximately 16%.

[Ischemic stroke. Prevalence of cardiovascular causes documented by an extensive cardiovascular workup in 110 patients]. / Les accidents vasculaires cérébraux ischémiques. Fréquence des étiologies cardiovasculaires documentées par un bilan cardiovasculaire approfondi. À propos de 110 cas.

PURPOSE: The ischemic cerebrovascular accidents (I CVA) correspond to a pathology widely dominated by atherosclerosis and embolic cardiopathies. Our work aimed to determine the frequency of the cardiovascular diseases among the patients who were previously victims of an I CVA and the interest of the cardiovascular assessment in the etiologic inquest. PATIENTS AND METHODS: We led a retrospective study in the cardiology service of the Avicenne military hospital of Marrakech about 110 cases of I CVA between January 2005 and August 2008. The electrocardiogram (ECG), Holter ECG, transthoracic echocardiography and Doppler echography of the cervical vessels were systematically made for all the patients. The transesophageal echocardiography was practice in a few patients. RESULTS: The average age of the patients was 60.8 years old (±12.14) with a male predominance (72%). Ninety-one percent of the patients presented at least one cardiovascular risk factor: hypertension (66.45%), diabetes (41.8%), smoking (35.45%). Cardiovascular antecedents were noted among 18.2% of the patients, the continuous atrial fibrillation comes first (9%). A carotid atheromatous excess was noted in 74 cases of which 24 with a significant plaque. The transesophageal echocardiography made to 13 patients showed a spontaneous echo contrast with a left atrial thrombus in four cases and a left atrial myxoma in one patient. CONCLUSION: Penetrating artery disease occupies 39%, large artery atherosclerosis 28% and cardiogenic stroke 18%. The cardiovascular assessment is indispensable, and the echocardiography is more interesting in presence of cardiopathy. Its therapeutic repercussion is modest.

[Usefulness of microalbuminuria in the metabolic syndrome as a predictor of cardiovascular disease. Prospective study about 78 cases]. / Intérêt de la microalbuminurie au sein du syndrome métabolique dans la prédiction des évènements cardiovasculaires. Étude prospective à propos de 78 cas.

AIM: Increased urinary albumin-excretion is a cardiovascular risk factor. The metabolic syndrome is associated with an increased risk of chronic kidney disease, cardiovascular disease and mortality. The aim of this prospective study was to explore the combined associations of microalbuminuria and metabolic syndrome with the risk of incident cardiovascular disease. METHODS: The present study involved 78 patients with metabolic syndrome between May 1 and July 30 in 2009 from cardiology clinic of military hospital in Marrakech. They were followed for 1 year. The metabolic syndrome was defined according to the criteria of International Diabetes Federation (IDF). Microalbuminuria was defined as a urinary albumin excretion of 30 to 300mg/d. RESULTS: The mean age was 56 years old. The prevalence of microalbuminuria was 38%. There was a significantly positive correlation between the number of components of the metabolic syndrome and the corresponding prevalence of microalbuminuria. Incidence rates of cardiovascular events were higher in the positive microalbuminuria group than the group without microalbuminuria, the difference was significant for composite criteria but not for each one probably because of the small size of effective and limited duration. CONCLUSIONS: There is a strong relationship between microalbuminuria and the metabolic syndrome. Microalbuminuria accounts for the increased risk of cardiovascular disease in patients with metabolic syndrome.

[Early surgery in infective endocarditis. Retrospective study apropos of 30 cases]. / Chirurgie précoce dans l'endocardite infectieuse. Etude rétrospective à propos de 30 cas.

AIM: The aim of this study is to stress the interest of the early surgery in infective endocarditis (IE), its indications and prognostic implications. METHODS: It is a retrospective descriptive study of 30 cases (29 men and 1 woman with an average age of 35+/-12 years) with IE underwent surgery management in the acute phase between September 1993 and June 2005. RESULTS: They were 25 rheumatic lesions, 2 aortic bicuspids and 3 mechanical valves prosthesis. Four twenty-six percent of the patients were operated for hemodynamic deterioration and 10% for embolic complication. We report 3 cases (that is to say 10%) of IE late form on prosthesis. Three patients died in the first post operative month by respectively total desinsertion of mitral prosthesis on peroperative, 1 septic shock at the 13th post operative day and 1 tamponade at the 14th postoperative day. On 72 months an average follow-up, 26 were controlled regularly: 25 evolved favourably and 1 died in third postoperative year (severe heart failure). CONCLUSION: A high early surgery rate is related to good long term results and does not increase in hospital mortality. The reduced mortality was particularly evident among patients with moderate to severe congestive heart failure.
