Postpartum cardiac failure in Sudanese-Sahelian Africa: Clinical prevalence in western Niger

Postpartum cardiac failure (PPCF) is the most frequent clinical form of heart failure in hospitalized women in Sudanese-Sahelian Africa. We have previously studied this disease in a hospital setting. Although the incidence is relatively high in rural areas, no systematic field study has been carried out. In this report, we describe a retrospective study conducted in the western part of Niger in July-August 1991. Sixty-two villages were visited and a thorough search for patients was initiated (from a population of 79,941 inhabitants, 19,941 females 14-40 years of age, corrected census of 1988). Twenty-eight patients from 27 villages were included. The subject patients were those presenting with predefined symptoms (dyspnea and cough) and physical signs (edema of the legs) of congestive heart failure during the six-month period following delivery. Apart fi-om arterial hypertension and previous PPCF, diagnosis of another cardiac disease was an exclusion criterion. The prevalence of PPCF was 1.40 per 1,000 females of child-bearing age. The clinical profiles of these cases were in accordance with those of a previous study in 1989 carried out at Niamey Hospital. These results were a mean +/- SD age of 28 +/- 7 years, multiparity (mean = 4 children), poor socioeconomic status, postpartum ablutions with hot water: and a high sodium intake. This is the first study on the clinical prevalence PPCF in a Sudanese/Sahelian population living in a rural area.
