Influenza, commonly known as the flu, is often dismissed as an unpleasant but ultimately manageable respiratory illness. however, recent research reveals a far more serious potential consequence: a dramatically heightened risk of both heart attack and stroke in the month following infection. Understanding this connection is crucial for protecting your cardiovascular health, especially during peak flu season.
Researchers at UCLA investigated the link between influenza infection and acute cardiovascular events. Their findings, published in late 2024, demonstrate a considerable and alarming increase in the risk of both heart attack and stroke during the 30 days following a confirmed flu diagnosis. Specifically, the study showed a four-times greater chance of experiencing a myocardial infarction (heart attack) and a five-times greater chance of suffering a stroke compared to individuals without a recent flu infection.
This isn't simply a correlation; the research suggests a direct causal link. The inflammatory response triggered by the flu virus can destabilize existing atherosclerotic plaques in arteries, increasing the likelihood of rupture and subsequent blockage, leading to either a heart attack or stroke.
