“…Une prise en charge multidisciplinaire incluant des diététiciens serait bénéfique pour l'amélioration de l'observance du régime hyposodé. En effet, la surconsommation de sel est décrite chez le sujet noir [6, 21]. Les surinfections broncho-pulmonaires, fréquentes dans d'autres études [14], étaient associées au risque de décès.…”

IntroductionL'insuffisance cardiaque (IC) est une cause fréquente de décès en Afrique. La présente étude a pour but de déterminer le taux de létalité de l'IC et de rechercher les facteurs associés.MéthodesIl s'agissait d'une étude rétrospective transversale réalisée dans le service de cardiologie du CHUL. Elle portait sur l'analyse de dossiers de patients hospitalisés pour IC gauche ou globale colligés de Janvier 2014 à Décembre 2016.Résultatsla létalité était de 10,3%. L'âge moyen des patients décédés (n=64) était de 57,4 ± 17 ans. Le délai moyen de prise en charge était de 15± 18 jours et la décompensation faisait suite à un écart de traitement chez 51,4% des patients décédés. L'association hypertension artérielle et diabète augmentait significativement le risque de décès (OR= 2,2 (1,2-6,6)). Les facteurs associés à la létalité étaient essentiellement: l'hypotension artérielle (OR=6,8(3,2-14,1)), l'insuffisance rénale sévère (OR=3,5(1,7-7,2)), un index cardio-thoracique supérieur à 0,7 (OR= 54,4 (15,3-193,1)), une altération sévère de la fraction d'éjection ventriculaire gauche (OR= 3,0(1,5-5,9)) et un taux élevé de NT-proBNP (OR=3,5(1,2-10,5)). La mortalité augmentait significativement avec le nombre de comorbidités. Les décès étaient dus dans 28,4% des cas à une complication extracardiaque.ConclusionLa létalité de l'IC est liée à la sévérité et à la précocité des lésions. Le retard de prise en charge et les comorbidités aggravent cette létalité. Le dépistage des facteurs de risque et l'éducation thérapeutique pourraient diminuer cette mortalité qui concerne des sujets relativement jeunes.

“…The global prevalence of raised BP in adults aged 18 years or older was 22% in 2014, with Africa being the most affected region with a 30% prevalence [ 3 ]. By and large, published international and WHO guidelines are unsuitable for application in many ethnically diverse populations of countries in SSA because their economic, ecological, sociocultural, and health care environments, poor infrastructure hindering health-promoting lifestyles, and unaffordability for the patients impede the adoption of recommended nonpharmacological and pharmacological treatment [ 23 , 30 , 32 , 68 - 70 ]. Moreover, good-quality data on hypertension in different ethnic populations in much of SSA are notoriously missing in the treatment guidelines, which are largely based on white populations, whereas cardiovascular disease varies with ethnic origin [ 71 ]; of the more than 180 studies that met the standards of the Eighth Joint National Committee, fewer than 30 were from nonwhite, non-African American groups [ 9 ].…”

“…For raised BP, the target is a 25% relative reduction in the prevalence of raised BP or to contain the prevalence of raised BP, according to national circumstances; the indicators are the age-standardized prevalence of raised BP among persons aged 18 years or older (defined as SBP ≥140 mm Hg, DBP ≥90 mm Hg, or both) and mean SBP. The Global Plan provides a roadmap for country-led action for the prevention and control of NCDs; any effective action by a national government will depend on the extent of understanding of its country-specific circumstances, for which there are huge data needs, and gaps in knowledge and evidence, for African countries [ 23 , 30 , 32 , 67 - 70 , 91 ]. There is an urgent need to systematically map evidence on hypertension and comorbidities from clinic-based and community-based data reflecting within-country circumstances, so that the implementation of strategies and actions to curb the epidemic of hypertension is evidence based at the local or hospital level, where the costs, impacts, and benefits of health technologies and strategies can be directly assessed.…”

BackgroundHypertension holds a unique place in population health and health care because it is the leading cause of cardiovascular disease and the most common noncommunicable condition seen in primary care worldwide. Without effective prevention and control, raised blood pressure significantly increases the risk of stroke, myocardial infarction, chronic kidney disease, heart failure, dementia, renal failure, and blindness. There is an urgent need for stakeholders—including individuals and families—across the health system, researchers, and decision makers to work collaboratively for improving prevention, screening and detection, diagnosis and evaluation, awareness, treatment and medication adherence, management, and control for people with or at high risk for hypertension. Meeting this need will help reduce the burden of hypertension-related disease, prevent complications, and reduce the need for hospitalization, costly interventions, and premature deaths.ObjectiveThis review aims to synthesize evidence on the epidemiological landscape and control of hypertension in Cameroon, and to identify elements that could potentially inform interventions to combat hypertension in this setting and elsewhere in sub-Saharan Africa.MethodsThe full search process will involve several steps, including selecting relevant databases, keywords, and Medical Subject Headings (MeSH); searching for relevant studies from the selected databases; searching OpenGrey and the Grey Literature Report for gray literature; hand searching in Google Scholar; and soliciting missed publications (if any) from relevant authors. We will select qualitative, quantitative, or mixed-methods studies with data on the epidemiology and control of hypertension in Cameroon. We will include published literature in French or English from electronic databases up to December 31, 2016, and involving adults aged 18 years or older. Both facility and population-based studies on hypertension will be included. Two reviewers of the team will independently search, screen, extract data, and assess the quality of selected studies using suitable tools. Selected studies will be analyzed by narrative synthesis, meta-analysis, or both, depending on the nature of the data retrieved in line with the review objectives.ResultsThis review is part of an ongoing research program on disease prevention and control in the context of the dual burden of communicable and noncommunicable diseases in Africa. The first results are expected in 2017.ConclusionsThis review will provide a comprehensive assessment of the burden of hypertension and control measures that have been designed and implemented in Cameroon. Findings will form the knowledge base relevant to stakeholders across the health system and researchers who are involved in hypertension prevention and control in the community and clinic settings in Cameroon, as a yardstick for similar African countries.Trial RegistrationPROSPERO registration number: CRD42017054950; http://www.crd.york.ac.uk/PROSPERO/ display_record.asp?ID=CRD42017054950 (...

Background: Hypertension is the leading cause of cardiovascular disease worldwide. Hypertensive disorders in pregnancy also constitute a major global health threat. There are different types of hypertension that can occur during pregnancy; with different mechanisms and consequences for mother and fetus. Objectives: To determine the frequency of hypertension (hypertension) during pregnancy. Document the risk factors for pregnancy-related hypertension. Review the material and fetal complications which determine the prognosis. Methods and Patients: This was a retrospective cross-sectional study from January 1 to June 30, 2022 in the Obstetrics and Gynecology Department of the Brazzaville Hospital and University Center. We noted 72 cases of hypertension among 1188 births admitted during the reference period. Hypertension was defined as blood pressure 40/90mmHg. Results: Hypertension was observed in 6% of those giving birth. The average age of the patients was 28 ± 8 years (range 15 to 39 years). The age group of 15 to 34 years was the most affected, 56 cases (778%). The risk factors were young age (15 -34 years), late transfer of women in labor, 49 cases (68%). Primiparity, 33 cases (45.8%), absence of prenatal consultation, 7 cases (9.7%), hypertension, 8 cases (11%), twinning, 4 cases (5%), fetal macrosomia, one case (1.3%). Maternal complications recorded were: 21 cases of eclampsia (29%), 6 cases of left ventricular failure (8.3%), 5 cases of anemia (6.9%), 2 cases of retroplacental hematoma (2.8%), 1 case of HELLP syndrome, as much renal failure. Fetal and neonatal complications were 23 cases of prematurity (32%), 10 cases of acute fetal distress (14%), 4 cases of hypotrophy (5.6%). Eleven cases of death (15.3%) were: 3 in utero. B in the neonatal period.
