Hypertension (HT) is a growing burden worldwide, leading to over 10 million deaths each year. In Brazzaville, the prevalence of HT was 32.5% in 2004. The mortality for stroke in 2008 and heart failure in 2013 were, respectively, 24% and 20.2%. May Measurement Month (MMM) is a global initiative initiated by the International Society of Hypertension aimed at raising awareness of HT and to act as a temporary solution to the lack of screening programmes worldwide. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in May 2017. Blood pressure (BP) measurement, the definition of HT and statistical analysis followed the standard MMM protocol. The screening was carried out in Brazzaville, and the screening sites were distributed in different districts of the city in public places and health facilities. A total of 3842 individuals were screened during MMM17. After multiple imputations, 1576 (41.0%) had HT. About 956 (29.7%) individuals not receiving anti-hypertensive medication, were hypertensive. Four hundred and nine (66.0%) individuals receiving anti-hypertensive medication, had uncontrolled BP. Systolic and diastolic BPs after adjustment for age and sex differed significantly in association with use of anti-hypertensive medication ( P < 0.0001), previous stroke ( P = 0.001 for systolic), and waist circumference ( P < 0.0001). MMM17 was the largest BP screening campaign undertaken in Congo. Almost one-third of screenees had untreated HT, and two-thirds of treated hypertensives were not well controlled. These results suggest that opportunistic screening can identify significant numbers with raised BP.

Background: To determine mortality causes and the associated factors. Patients and Method: This cross-sectional study was conducted from June 2014 to May 2015 (1 year) in the department of cardiology at University and teaching Hospital of Brazzaville. Patients admitted for cardiovascular diseases were included. Patients admitted for cardiovascular disease in other departments of the hospital, or without cardiovascular diseases were not included. Results: In total, 1035 patients, 605 women (5804%) were included. Mean age was 57.1 ± 7 years (range: 18-85 years). The patients were: elderly (n = 498, 48.1%), educated (n = 809, 78.1%), low-income (n = 253, 24.2%). The medical history of patients was: hypertension (n = 440, 42.5%), diabetes (n = 316, 30.5%), reduced physical activity (n = 154, 14.9%), excessive alcohol intake (n = 56, 5.4%). Heart failure was reported in 386 cases (37.3%). The mortality rate was 8% (n = 83); the mean age of deceased was 61.9 ± 7.3 years (p < 0.0001). The associated diseases in death were dilated cardiomyopathy (n = 37, 44.

L'objectif de cette étude est de contribuer à l'amélioration de la prise en charge des patients porteurs de cardiomyopathies dilatées (CMD) à Brazzaville. Cette étude, prospective et analytique, a été réalisée au CHU de Brazzaville entre le 1 er Janvier 2014 et le 30 Juin 2015. Elle a inclus les patients hospitalisés dans le service de cardiologie pour une insuffisance cardiaque (IC) en rapport avec une CMD. L'étude a porté sur 100 patients. La fréquence hospitalière de la CMD était de 32,1%. Il s'agissait de 38 hommes (38%) et 62 femmes (62%), âgés en moyenne de 52,9 ± 17,1 ans. L'IC était globale dans 72 cas (72%). L'ECG s'inscrivait en rythme sinusal (95%), et objectivait une hypertrophie ventriculaire gauche (40%), un bloc de branche gauche (16%), et une fibrillation auriculaire (5%). La fraction d'éjection du ventricule gauche (VG) était en moyenne de 33,4 ± 6,8%, et le diamètre télédiastolique du VG de 65,5 ± 7,0 mm. Le traitement comportait un diurétique de l'anse (100%), un IEC/ARA2 (100%), un bêtabloquant (38%), un digitalique (30%), un anti-aldostérone (16%), et un anti-vitamine K (11%). Au terme d'un suivi de 12 mois, le taux de létalité globale était de 9%, le taux de réhospitalisation de 12%, et le taux de perdus de vue de 41%. Cette étude a montré que la CMD est une affection fréquente, et une des principales causes d'insuffisance cardiaque. La durée de suivi brève et le nombre important de perdus de vue ne permettent pas d'en évaluer la survie dans notre contexte.
