Heart Failure

 

Individuals with higher levels of cardiac troponin in their blood are at greater risk for developing heart failure for the first time, according to a meta-analysis published in JACC: Heart Failure.

The prevalence of left ventricular systolic dysfunction (LVSD) has declined over the last 30 years, and heart failure patients are increasingly demonstrating preserved ejection fraction versus reduced ejection fraction, according to a study published in JACC: Cardiovascular Imaging.

Previously sedentary, middle-aged adults who devote themselves to regular aerobic exercise for two years can increase their maximal oxygen uptake and decrease cardiac stiffness, according to new research published in Circulation.

Women who undergo hysterectomies—especially those under 35 years old—are nearly five times more likely to develop congestive heart failure and are at increased risk for a slew of other coronary complications, according to a study of more than 2,000 Minnesota women.

More than 10 percent of heart transplant recipients developed cancer between one and five years post-transplantation—most commonly skin cancer—according to a study published in the Journal of the American College of Cardiology.
