Impact of heart disease on maternal, fetal and neonatal outcomes in a low-resource setting

Abstract

Screening echocardiography was performed in 3506 women. The prevalence of heart disease was 17 per 1000 women (95% CI 13 to 21); 15 per 1000 was rheumatic heart disease. Only 3.4% of women (2/58) had prior diagnosis. Cardiovascular complications occurred in 51% of women with heart disease, most commonly heart failure. Per cent attributable risk of heart disease on maternal mortality was 88.6% in the exposed population and 10.8% in the overall population. Population attributable risk of heart disease on fetal death was 1.1% and 6.0% for neonatal mortality CONCLUSIONS: Occult maternal heart disease may be responsible for a substantial proportion of adverse pregnancy outcomes in low-resource settings. Rheumatic heart disease is, by far, the most common condition, urging global prioritisation of this neglected cardiovascular disease.
