Peripartum Cardiomyopathy: A Review Article.

Peripartum cardiomyopathy (PPCM) is an important cause of heart failure (HF) in northern Nigeria and many other regions of the world. Although the aetiology is unknown, several aetiopathogenic mechanisms have been proposed, including myocarditis, vasculo-hormonal (16-kDa prolactin and Cathepsin D), genetic susceptibility and selenium deficiency hypotheses. The peripartum cardiomyopathy in Nigeria (PEACE) registry has revealed that three socioeconomic factors (lack of formal education, unemployment, underweight status), pre-eclampsia and selenium deficiency were independently associated with higher risk for PPCM. However the customary postpartum practices previously implicated in the aetio-pathogenesis of postpartum cardiac failure, comprising regular hot baths and pap enriched with dried lake salt, were not associated with PPCM. Maternal age <20 years, tachycardia, hypotension and ejection fraction <25% independently increased the risk for mortality. Regular use of beta-blockers and obesity were independently associated with higher survival, and selenium supplementation is a promising treatment strategy for PPCM.
