Heart valve prolapse linked to problems beyond the valve
Researchers identified seven genetic regions linked to valve prolapse or a related abnormality in UK Biobank participants, alongside associations with heart and blood vessel disease.
Limit: The imaging tool prioritized finding cases over avoiding false positives

In an observational study, researchers analyzed heart scans from 55,353 UK Biobank participants. A computer program identified 2,191 with mitral valve prolapse, in which a heart valve bulges backward, and 2,475 with an abnormality of its attachment.
Genetic analyses in participants of European ancestry identified seven associated DNA regions. The analysis highlighted genes associated with aortic disease or heart failure. A genetic score for prolapse was associated with high blood pressure and aortic aneurysm or dissection—bulging or tearing of the body’s main artery. Prolapse was associated with later atrial fibrillation, an irregular heartbeat, and heart failure after adjustment for other risk factors and heart measurements. Compared with participants without prolapse, hazard ratios—measures of relative risk—were 1.58 and 1.43, respectively. The range of likely values for heart failure included no difference.
Why it matters
For age-related heart disease, the work bears on whether a valve abnormality should be assessed as part of a broader condition involving the heart muscle and aorta.
Caveats
This observational study cannot establish cause and effect, and its imaging tool prioritized finding cases over avoiding false positives. The report is a conference abstract, and the genetic analysis covered participants of European ancestry.
