Background: Racial differences between Black and Non-black women with peripertum cardiomyopathy (PPCM) have been observed. The aim was to test the hypothesis that racial differences in degree of left ventricular (LV) dysfunction at presentation and recovery occur in PPCM using strain imaging.
Methods: We studied 100 PPCM patients in the multicenter Investigation in Pregnancy Associated Cardiomyopathy study [LV ejection fraction (EF) <45% within 2 months of delivery]. Speckle tracking echo from 3 apical views for global longitudinal strain (GLS) was done at entry, 6-month-follow and 1-year. Patients with lack of LV recovery were predefined as LVEF < 50% at 1 year, death, heart transplant or LV assist device (LVAD).
Results: PPCM patients with Black race had greater degree of LV dysfunction at each time point: LVEF was 31.7±1.8%* vs.35.9±1.1% at entry, *p=0.048; 47.0±2.2%* vs. 53.0±1.4% at 6 mo, *p=0.024; and 47.6±2.2%* vs. 55.4±1.3% at 1 year, *p=0.003. GLS (absolute values) was also lower in Black vs. Non-black patients: 10.0±0.8%* vs. 12.4±0.5% at entry, *p=0.014; 16.5±1.0%* vs. 19.0±0.6% at 6 mo., p=0.040*; 16.8±1.1%* vs. 19.4±0.6% at 1 yr, p=0.043).
Conclusions: Racial differences in degree of LV dysfunction and recovery were observed in PPCM with Black patients having comparatively greater LV dysfunction by both EF and GLS.
