Viruses Triple Heart Attack, Stroke Risk; Vaccines Offer Protection

New study reveals viral infections dramatically increase heart attack and stroke risk. Influenza quadruples heart attack risk, COVID triples stroke risk. Vaccination offers significant cardiovascular protection.

This research fundamentally changes how we understand cardiovascular risk by demonstrating that common viral infections—from seasonal flu to chronic conditions like HIV and shingles—significantly increase heart attack and stroke likelihood. For the general public, this means that staying current with recommended vaccinations isn't just about preventing illness but actively protecting cardiovascular health. The findings are particularly crucial for the millions of people with existing heart conditions or risk factors, as they face compounded dangers from viral infections. Given that cardiovascular disease remains the leading cause of death worldwide, this research provides compelling evidence that routine vaccination could substantially reduce global heart attack and stroke rates, making preventive healthcare an essential component of cardiovascular protection.
