Viral Infections Linked to Significantly Increased Heart Attack and Stroke Risk
Los Angeles, CA – November 2nd, 2025 - New research reveals a strong connection between common viral infections, including influenza and COVID-19, and a heightened risk of serious cardiovascular events like heart attacks and strokes. A study published in the Journal of the American Heart Association by a team led by kosuke Kawai at the University of California, Los Angeles, found that the risk of cardiovascular disease increases approximately threefold in the short term following a SARS-CoV-2 infection.
The findings underscore the often-overlooked cardiovascular consequences of viral illnesses, impacting millions and potentially straining healthcare systems. While COVID-19 presents the most immediate and dramatic risk, other viruses also contribute to longer-term cardiovascular issues. Researchers attribute this increased risk to the body’s immune response, which releases inflammatory substances and promotes blood clotting – processes that directly affect the cardiovascular system.
The study authors emphasize the importance of preventative measures, notably vaccination. An overview study from 2022 demonstrated that influenza vaccination is associated with a 34 percent reduction in the risk of experiencing a major cardiovascular event. This research, initially reported on Deutschlandfunk today, reinforces the need for increased vaccination rates against viruses known to impact heart health.
