[Left ventricular geometry study in black African hypertensives]. / Étude de la géométrie ventriculaire gauche chez des hypertendus Noirs Africains.

AIM: To determine the prevalence and determinants of different types of echocardiographic left ventricular remodeling in African black hypertensive patients. PATIENTS AND METHODS: A transversal descriptive study was conducted from January 1, 2015, to March 31, 2016, in the external explorations department of the Abidjan Heart Institute-Côte d'Ivoire. Transthoracic cardiac echo-graphs were performed in 524 (251 women) hypertensive subjects according to the American Society of Echocardiography convention. RESULTS: Twenty-nine percent of hypertensive patients had cardiac remodeling (in women and men, respectively, concentric remodeling 14.7 % and 15.7 %; concentric hypertrophy 6 % and 10.3 %; eccentric hypertrophy 7.6 % and 3.7 %). Only systolic and diastolic blood pressure levels were significantly correlated with left ventricular mass indexed to body surface area. CONCLUSION: This study showed a significant proportion of hypertensives with abnormal left ventricular geometry and confirmed the relationship between blood pressure level and left ventricular geometry change.

May Measurement Month 2017: an analysis of blood pressure screening results in Cote d'Ivoire-Sub-Saharan Africa.

Elevated blood pressure (BP) is a growing burden worldwide, leading to over 10 million deaths each year. In Cote d'Ivoire, high BP is the first risk factor for stroke and myocardial infarction. May Measurement Month (MMM) is a global initiative of the International Society of Hypertension aimed at raising awareness of high BP 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. BP measurement, the definition of hypertension and statistical analysis followed the standard MMM17 protocol. A Coordinators Team was created. All doctors in cardiology training of Abidjan Institute of Cardiology (N = 72) were briefed to carry out the MMM study as investigators, and 55 sites were created. These were major urban transport stations, supermarkets and markets, and churches. BP was calculated from the mean of the 2nd and 3rd readings, and hypertension was defined as a systolic BP of at least 140 mmHg and/or a diastolic BP of at least 90 mmHg or being on BP-lowering treatment. We screened 24 563 individuals during MMM17, with mean age of 37 years. After multiple imputations, 5015 (20.4%) had hypertension. Of individuals not receiving anti-hypertensive medication, 3943 (16.8%) were hypertensive. Of individuals receiving anti-hypertensive medication, 583 (54.4%) had uncontrolled BP. MMM17 was the largest BP screening campaign undertaken in Cote d'Ivoire. MMM allowed us to identify many undiagnosed and inadequately treated hypertension cases and could usefully lower the burden attributed to increased BP. MMM should be continued.
