Antibiotic class linked to heart-valve regurgitation
Two large US studies by the same researchers show similar results
Fluoroquinolone antibiotics may double the risk of regurgitation in valves on the left side of the heart, a study shows.
The finding comes from an analysis of data on more than nine million patients from a US medical claims database that researchers used to compare 12,500 people who developed aortic or mitral valve disease with more than 125,000 who did not.
