Study Helps Unravel Why Young, Pregnant Women Develop Heart Failure Similar to That of Older Patients
PHILADELPHIA— Researchers at Penn Medicine have identified more genetic mutations that strongly predispose younger, otherwise healthy women to peripartum cardiomyopathy (PPCM), a rare condition characterized by weakness of the heart muscle that begins sometime during the final month of pregnancy through five months after delivery. PPCM can cause severe heart failure and often leads to lifelong heart failure and even death. The study is published today in Circulation.
PPCM affects women in one out of every 2,000 deliveries worldwide, with about a third of those women developing heart failure for life, and about five percent of them dying within a few years. Maternal mortality in the United States has doubled in the last 20 years, and PPCM is a leading cause of these deaths. Previously, the reasons behind why women developed PPCM remained a mystery until a 2016 study strongly suggested that some genetic mutations predispose women to the disease. Zoltan P. Arany, MD, PHD, the Samuel Bellet Professor of Cardiology in the Perelman School of Medicine at the University of Pennsylvania was also the senior author of that study. This newly released study shines a light on four more genetic variants that had not previously been associated with PPCM. It found that this genetic profile is highly similar to that found in patients with non-ischemic dilated cardiomyopathy (DCM), a very similar disease that typically impacts middle-aged men and women, and one that the medical community knows more about.
