Abstract

Peripartum cardiomyopathy (PPCM) is a rare and potentially life-threatening disease associated with pregnancy. There are limited data regarding the outcome of PPCM and its predictive factors in sub-Saharan African patients. We prospectively conducted a double-center (cardiology unit of the department of medicine, Regional Hospital Center of Tenkodogo, Burkina Faso and the department of cardiology of the National Referral Teaching Hospital of N´Djamena, Chad) cohort study in patients with PPCM. Patients were consecutively enrolled from January 2015 to December 2017. Outcomes of interest were left ventricular recovery and poor outcome at one year. Ninety-four patients enrolled with a median age of 28 years. At one-year follow-up, 40.5% of them recovered their left ventricular function. Cox multiple regression analysis revealed that higher left ventricle ejection fraction (LVEF), lower natremia and use of betablockers were baseline variables predicting this end-point. Of the entire study population, 26.60% exhibited the composite end-point of death (n=15) or remaining in New York Heart Association (NYHA) class III-IV or LVEF < 35%. Predictors of poor outcome were lower LVEF at baseline, hyponatremia and use of digoxin. The current cohort study demonstrated that PPCM in sub-Saharan Africa is associated with limited myocardial recovery and significant rate of poor outcome at one year. Therefore, additional studies are needed to better address the disease.
