A common antibiotic could lead to heart problems: study

A group of researchers have found a link between two types of heart problems and one of the most commonly prescribed classes of antibiotics.
The study that was published in the Journal of the American College of Cardiology said, researchers found that current users of fluoroquinolone antibiotics, such as Ciprofloxacin or Cipro, face a 2.4 times greater risk of developing aortic and mitral regurgitation, where the blood backflows into the heart, compared to patients who take amoxicillin, a different type of antibiotic. The greatest risk is within 30 days of use.
"You can send patients home with a once-a-day pill," this class of antibiotics is very convenient, but for the majority of cases, especially community-related infections, they're not needed. The inappropriate prescribing may cause both antibiotic resistance as well as serious heart problems," said study lead author Mahyar Etminan, Associate Professor at the University of British Columbia.
They defined current fluoroquinolone exposure as an active prescription or 30 days before the adverse event, recent exposure as within days 31 to 60, and past exposure as within 61 to 365 days prior to an incident.
They compared fluoroquinolone use with amoxicillin and azithromycin.
"This study highlights the need to be thoughtful when prescribing antibiotics, which can sometimes cause harm," said Bruce Carleton from BC Children's Hospital in Canada.
