RESUMO
OBJECTIVE: To assess the basic physical condition of chronic heart failure's Cameroonian patients. PATIENTS AND METHODS: We carried out a cross-sectional study from February to June 2020 at the Yaoundé Central and General Hospitals, including all consenting adults with stage I or II chronic heart failure of the New York Heart Association without sign of decompensation and received in outpatient consultation. Socio-demographic data and the level of physical activity assessed according to the International Questionnaire on PhysicalActivity were recorded. Quality of Life was evaluated using the "Minnesota Living with Heart Failure Questionnaire". Associated factors were analysed using the Chi-square test, the strength of association expressed by the odds ratio, and its 95% confidence interval. The significance level was 0.05. RESULTS: We recruited 102 participants, including 60 women with a median age of 64 [56,68]. Daily physical activity was moderate in 54% of participants and low in 45%, with no significant difference between the sexes (p = 0.3). About 39.2% of patients had an altered physical condition, and the most effective associated factors were obesity (p = 0.01), low daily physical activity (p = 0.002) and non-compliance to the treatment (p = 0.03). The mean Quality of Life score was low (36.7 ± 22.4), and the deterioration in physical condition harmed it (p < 0.001). CONCLUSION: More than a third of the study population had a poor physical condition, which negatively affected their Quality of Life. Therefore, we can suggest that prescribing appropriate physical activity should be an integral part of heart failure management in our context.

Essentials Venous thromboembolism (VTE) is among the three main causes of cardiovascular disease worldwide. This review is the first to summarize the epidemiology of VTE in African populations. The prevalence of VTE in Africa is high following surgery, in pregnancy and post-partum. At least one quarter of patients at risk of VTE in Africa are not receiving prophylaxis. SUMMARY: Background Venous thromboembolism (VTE) is among the three leading causes of cardiovascular disease worldwide. Despite its high burden, there has been no previous study summarizing the epidemiology of VTE in African populations. Hence, we conducted this systematic review to determine the prevalence, incidence and mortality associated with VTE, and to evaluate the use of VTE prophylaxis in Africa. Methods We searched PubMed, Scopus and African Journals Online to identify articles published on VTE in Africa from inception to November 19, 2016, without language restriction. The reference list of eligible articles were further scrutinized to identify potential additional studies. Results Overall, we included 21 studies. The great majority of the studies yielded a moderate risk of bias. The prevalence of deep vein thrombosis (DVT) varied between 2.4% and 9.6% in postoperative patients, and between 380 and 448 per 100 000 births per year in pregnant and postpartum women. The prevalence of pulmonary embolism (PE) in medical patients varied between 0.14% and 61.5%, with a mortality rate of PE between 40% and 69.5%. The case-fatality rate after surgery was 60%. Overall, 31.7-75% of the patients were at risk of VTE, and between 34.2% and 96.5% of these received VTE prophylaxis. Conclusion The prevalence of VTE and associated mortality are high following surgery, and in pregnant and postpartum women in Africa. At least one-quarter of patients who are at risk for VTE in Africa are not receiving prophylaxis. These results are generated from studies with small sample size, highlighting an urgent need for well-designed studies with larger sample size to evaluate the true burden of VTE in Africa.
