Inhospital cardiovascular morbidity and mortality in the department of internal medicine at CHU Kigali (Rwanda)

ABSTRACT

Cardiovascular diseases (CVD) formerly considered as developed countries pandemic, are becoming nowadays increasingly ubiquitous in developing countries, where in addition to a steady increase in different risk factors, there is substantial inaccessibility to health care. However, data about the burden of CVD is lacking in many sub-Saharan African countries, and their morbimortality characteristics have been poorly described. Authors carried out a descriptive and retrospective study over a 12-month period, to describe the inhospital morbidity and mortality of CVD in the Department of Internal Medicine at University Teaching Hospital in Kigali City. Data were collected from 226 CVD cases (91 males and 135 females). The patients' age ranged from 26 to 94 years (mean age of 47.17 ± 16.04). The 226 CVD cases account for the 8.2% of hospitalized patients. Hypertension was the principal cause of death (43.1% of deaths) and the predominant cause of patients' admission (42.9%), followed by cardiomyopathies (11.9%) and valvular heart diseases (11.5%). The association between a CVD and HIV/AIDS infection was observed in 23.9% of the total patients, but no causality relationship was investigated. Isolated heart failure takes the first place (33.6%) among the cardiovascular complications, followed by stroke (14.2%) and isolated renal failure (7.5%). Findings of this study confirm the importance of CVD in CHU Kigali, not only by their inhospital frequency but also- and especially by their lethality rate and their complications associated. This study stresses also a real need of CVD community survey in Rwanda
