Winter Health Alert: Viruses and Heart Risks Uncovered

New research highlights the increased risk of heart attacks and strokes triggered by common respiratory viruses like flu and COVID. The study, based on a meta-analysis of over 11,000 papers, shows how infections act as a matchstick to ignite cardiovascular events, especially in individuals with existing health risks.

Winter brings more than just cold days—it also ushers in a season of health concerns, with respiratory viruses emerging as a significant risk factor for heart attacks and strokes, according to research by Murdoch Children's Research Institute and Curtin University.

Meta-analysis of over 11,000 scientific papers reveals that viral infections such as influenza and COVID can dramatically increase the short-term risk of heart attacks and strokes, particularly for individuals with pre-existing health conditions.

Experts suggest vaccination as a preventive measure, emphasizing that protecting against infections could mitigate cardiovascular events and ease the burden on health systems and communities.
