Introduction: Heart failure is a complex syndrome and very frequently observed and secondary to the outcome of many advanced heart diseases. It is made up of a set of symptoms that reflect the tissue and visceral consequences of heart failure. The objective was to determine the hospital prevalence and to describe the management of heart failure in the medical department of Tombouctou hospital in Mali. Methods: This is a descriptive cross-sectional study with retrospective data collection, carried out over 24 months and involving the analysis of 266 records of patients hospitalized for heart failure. Results: The frequency of heart failure was 17.6% with a female predominance. The average age was 48 years with extremes of 16 and 90 years. Cardiovascular risk factors were dominated by high blood pressure with 38%. Global heart failure was the mode of discovery in 72.2% of cases. The etiologies were dominated by hypertensive dilated cardiomyopathy in 36.8% and peripartum cardiomyopathy in 32% of cases. The majority of our patients benefited from diuretic treatment, i.e. 95.9% frequency; with a favorable evolution in 96.2% of cases. We recorded 10 deaths, i.e. a lethality of 3.7%. We report some difficulties encountered during our security study because Tombouctou is a war zone and the lack of a technical platform for biology such as (BNP or NT-proBNP). Conclusion: Heart failure is a real public health problem. Its prevalence is increasing due to the aging of the population and especially the poor management of arterial hypertension in our context.
