Epidemiological profile of hypertensive disease and renal risk factors in black Africa.
OBJECTIVE
To describe the characteristics and renal function of hypertensive patients at their first hospital admission in Sub-Saharan Africa.


METHODS
Retrospective study of all hypertensive patients.


METHODS
Department of Cardiology and Internal Medicine of Yalgado Ouedraogo National Hospital in Burkina Faso, a country in Sub-Saharan Africa.


METHODS
Three hundred and seventeen consecutive hypertensive patients (systolic blood pressure > or = 160 mmHg or diastolic blood pressure > or = 90 mmHg, or both, or patients receiving antihypertensive treatment) referred between 1 November 1988 and 31 October 1990.


RESULTS
The hypertensive patients accounted for 36.5% of admissions and included 198 males and 119 females (mean +/- SD age 49 +/- 14 years). Two-thirds of the patients belonged to the poorer socio-economic groups. Hospital admission was necessary because of the symptoms and complications of hypertension: 43% had diastolic blood pressure > 130 mmHg, 73.5% had at least one target organ affected and 38.2% had renal involvement in the form of chronic renal failure or as proteinuria > 1.5 g/24 h. Patients with renal involvement were younger and had blood pressure that responded less well to acute treatment. One-fifth of the patients died during their hospital stay, and most of these had impaired renal function.
