    Introduction: l'insuffisance cardiaque (IC) est une cause frĂ©quente de dĂ©cĂšs en Afrique. La prĂ©sente Ă©tude a pour but de dĂ©terminer le taux de lĂ©talitĂ© de l'IC et de rechercher les facteurs associĂ©s. MĂ©thodes: il s'agissait d'une Ă©tude rĂ©trospective transversale rĂ©alisĂ©e dans le service de cardiologie du CHUL. Elle portait sur l'analyse de dossiers de patients hospitalisĂ©s pour IC gauche ou globale colligĂ©s de Janvier 2014 Ă  DĂ©cembre 2016. RĂ©sultats: la lĂ©talitĂ© Ă©tait de 10,3%. L'Ăąge moyen des patients dĂ©cĂ©dĂ©s (n=64) Ă©tait de 57,4 ± 17 ans. Le dĂ©lai moyen de prise en charge Ă©tait de 15± 18 jours et la dĂ©compensation faisait suite Ă  un Ă©cart de traitement chez 51,4% des patients dĂ©cĂ©dĂ©s. L'association hypertension artĂ©rielle et diabĂšte augmentait significativement le risque de dĂ©cĂšs (OR= 2,2 (1,2-6,6)). Les facteurs associĂ©s Ă  la lĂ©talitĂ© Ă©taient essentiellement: l'hypotension artĂ©rielle (OR=6,8(3,2-14,1)), l'insuffisance rĂ©nale sĂ©vĂšre (OR=3,5(1,7-7,2)), un index cardio-thoracique supĂ©rieur Ă  0,7 (OR= 54,4 (15,3-193,1)), une altĂ©ration sĂ©vĂšre de la fraction d'Ă©jection ventriculaire gauche (OR= 3,0(1,5-5,9)) et un taux Ă©levĂ© de NT-proBNP (OR=3,5(1,2-10,5)). La mortalitĂ© augmentait significativement avec le nombre de comorbiditĂ©s. Les dĂ©cĂšs Ă©taient dus dans 28,4% des cas Ă  une complication extracardiaque. Conclusion: la lĂ©talitĂ© de l'IC est liĂ©e Ă  la sĂ©vĂ©ritĂ© et Ă  la prĂ©cocitĂ© des lĂ©sions. Le retard de prise en charge et les comorbiditĂ©s aggravent cette lĂ©talitĂ©. Le dĂ©pistage des facteurs de risque et l'Ă©ducation thĂ©rapeutique pourraient diminuer cette mortalitĂ© qui concerne des sujets relativement jeunes

    Abstract Background. Sub-Saharan Africa experiences an epidemic surge in hypertension. Studies in African Americans led to the recommendation to initiate antihypertensive treatment in Blacks with a diuretic or a low-dose fixed combination including a diuretic. We mounted the Newer versus Older Antihypertensive Agents in African Hypertensive Patients (NOAAH) trial to compare in native African patients a fixed combination of newer drugs, not involving a diuretic, with a combination of older drugs including a diuretic. Methods. Patients aged 30-69 years with uncomplicated hypertension (140-179/90-109 mmHg) and two or fewer associated risk factors are eligible. After a 4-week run-in period off treatment, 180 patients will be randomized to once daily bisoprolol/hydrochlorothiazide 5/6.25 mg or amlodipine/valsartan 5/160 mg. To attain and maintain blood pressure below 140/90 mmHg during 6 months of follow-up, the doses of bisoprolol and amlodipine in the combination tablets will be increased to 10 mg/day with the possible addition of α-methyldopa or hydralazine. NOAAH is powered to demonstrate a 5-mmHg between-group difference in sitting systolic pressure with a two-sided p-value of 0.01 and 90% power. NOAAH is investigator-led and complies with the Helsinki declaration. Results. Six centers in four sub-Saharan countries started patient recruitment on September 1, 2010. On December 1, 195 patients were screened, 171 were enrolled, and 51 were randomized and followed up. The trial will be completed in the third quarter of 2011. Conclusions. NOAAH (NCT01030458) is the first randomized multicenter trial of antihypertensive medications in hypertensive patients born and living in sub-Saharan Africa.status: publishe
