For the past few weeks, research journals have been publishing reports on the connection between medications that reduce high blood pressure and COVID-19. The concern is that the medications might increase the abundance of the receptor that SARS-CoV-2—the virus that causes COVID-19—uses to enter cells. Boosting levels of these ACE2 receptors on lung and heart cells could give the virus more cellular entry points to target and potentially make symptoms of the disease more severe.
It’s a hypothesis that is important to test, notes Carlos Ferrario, a professor of general surgery at Wake Forest School of Medicine who specializes in research on antihypertensive drugs.
So far, the data supporting the connection between blood pressure medications—specifically, angiotensin-converting-enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs)—and COVID-19 are scant. Yet media coverage of the connection has ...
