In northern Mali, few data exist, hence the interest of this study with the objective of studying the epidemiological, clinical and therapeutic and evolutionary aspects of Heart failure at the regional hospital of Gao. Patients and Methods: This was a cross-sectional, descriptive study that took place from July 2022 to June 2023 in the medical department at Gao Hospital. Results: The hospital prevalence of heart failure was 44.1%. The mean age was 47.30 ± 20 years (range: 16-88). Hypertension was the most common with 46.1%, followed by a sedentary lifestyle, and diabetes with 18.2% and 8.3% respectively;NYHA stage III-IV dyspnea was found in 83.9%. Reduced EF heart failure was present in 110 patients (76.9%), seventeen cases with moderately reduced EF (11.9%) and sixteen patients had preserved EF (11.2%). Global heart failure was the dominant (91.6%). The main etiologies of heart failure were dominated by hypertensive heart disease in 46 patients (32.2%), followed by postpartum cardiomyopathy with 43 cases (30.1%), primary dilated cardiomyopathy in 18 patients (12.6%), ischemic heart disease in 16 patients with 11.2%. Seven cases of valvular heart disease, or 4.9%. The evolution was favorable under treatment in 104 patients or 72.7%. In-hospital mortality was 14.7%. Conclusion: Heart failure is a common condition in sub-Saharan Africa, particularly in our country.展开更多

Therefore, harmonizing the spleen and stomach is of great importance in treatment of diseases. In this paper, based on GAO＇s academic ideas of acupuncture and moxibustion, the different rules of harmonizing the spleen and stomach for internal miscellaneous diseases and carefully supplementing spleen and stomach for externally-contracted diseases were elaborated by starting with the acupoint selection prescriptions and harmonizing the spleen and stomach. In addition, time acupuncture and pattern differentiation moxibustion application and other treatment characteristics were put forward. The experience of professor GAO Yu-chun in acupuncture manipulation of ＂harmonizing the spleen and stomach＂ was summarized in detail from five aspects for learning and reference.展开更多
