Male, Female Hearts Don’t Age in the Same Way
A federally funded analysis of MRI scans of the aging hearts of nearly 3,000 adults shows significant differences in the way male and female hearts change over time. Results of the research, led by investigators at Johns Hopkins, do not explain exactly what causes the sex-based differences, but they may shed light on different forms of heart failure seen in men and women that may require the development of gender-specific treatments, the scientists say. “Our results are a striking demonstration of the concept that heart disease may have different pathophysiology in men and women and of the need for tailored treatments that address such important biologic differences,” says senior study author Joao Lima, M.D., M.B.A., a professor of medicine and radiological science at the Johns Hopkins University School of Medicine and director of cardiovascular imaging at its Heart and Vascular Institute. The research, published online Oct. 20 in the journal Radiology, is believed to be the first long-term follow-up using MRI showing how hearts change as they age. Previous studies have assessed heart changes over time using ultrasound, but, the researchers say, MRI scans tend to provide more detailed images — and more reliable information — about the structure and function of the heart muscle.
