Right ventricular function in peripartum cardiomyopathy at presentation is associated with subsequent left ventricular recovery and clinical outcomes
Blauwet LA, Delgado-montero A, Ryo K, et al. Right Ventricular Function in Peripartum Cardiomyopathy at Presentation Is Associated With Subsequent Left Ventricular Recovery and Clinical Outcomes. Circ Heart Fail. 2016;9(5) DOI: 10.1161/CIRCHEARTFAILURE.115.002756
BACKGROUND: Peripartum cardiomyopathy has variable disease progression and left ventricular (LV) recovery. We hypothesized that baseline right ventricular (RV) size and function are associated with LV recovery and outcome.
METHODS AND RESULTS: Investigations of Pregnancy-Associated Cardiomyopathy was a prospective 30-center study of 100 peripartum cardiomyopathy women with LV ejection fraction (LVEF)
CONCLUSIONS: Peripartum cardiomyopathy patients had a high incidence of LV recovery, but a significant minority had persistent LV dysfunction or a major clinical event by 1 year. RV function per echocardiographic fractional area change at presentation was associated with subsequent LV recovery and clinical outcomes and thus is prognostically important.
