ABSTRACT

Background: Peripartum cardiomyopathy (PPCM) disproportionately affects women of African descent, however knowledge about this disease in African countries is limited.

Objectives: To describe the phenotype of women with PPCM seen at a referral hospital in Zambia and examine outcomes at 6 months.

Methods: A prospective observational study describing characteristics and 6-month outcomes was performed at the University Teaching Hospital Echocardiography Lab in Lusaka, Zambia.

Results: We enrolled 45 participants with PPCM and 38 were seen at 6-month follow up; 3 (7 %) died and 4 (9 %) were lost to follow up. Mean age was 32.9 years (SD:7.0); mean BMI was 25.3 kg/m (SD:4.1), mean parity was 3.4 (SD:2.2) children and twin pregnancies occurred in 4 (9 %). Median time from symptom onset to diagnosis was 60 days (IQR: 1-280). 20 (44 %) reported gestational hypertension and 10 (22 %) reported preeclampsia. Baseline median left ventricular ejection fraction (LVEF) was 36 % (IQR: 11-45), median left ventricular end-diastolic volume (LVEDV) was 150 mL (IQR: 58-229) and 79 % described New York Heart Association (NYHA) functional class IV symptoms. Median LVEF after 6 months was 49 % (IQR: 23-68;  < 0.001) and median LVEDV was 121 mL (IQR: 66-200;  < 0.001). At 6-month follow up 45 % had LVEF ≥ 50 %, 42 % had LVEDV ≤ 106 mL and 1 (3 %) had NYHA functional class IV symptoms.

Conclusions: Hypertension was prevalent in this cohort. Overall mortality rate was low and clinically significant improvements in cardiac parameters were seen in over 40%. Further research is needed to identify and mitigate gaps in diagnosis and management.
