New Research Highlights a Hidden Threat
A groundbreaking scientific statement released by the American Heart Association (AHA) has revealed a strong connection between viral infections and cardiovascular disease. Published in the AHA’s journal Circulation, the research concludes that both acute and chronic viral infections can substantially raise the likelihood of heart attacks, strokes, and other serious cardiovascular complications.
Key Findings from the Report
According to the AHA’s review, infections such as influenza, COVID-19, and long-term viruses like HIV and hepatitis C (HCV) can all contribute to cardiovascular issues. Short-term infections, like the flu or SARS-CoV-2, often trigger inflammation and clotting that may lead to sudden events such as heart attacks or ischemic strokes. On the other hand, chronic infections can silently damage blood vessels over years, increasing the risk of heart failure and artery disease later in life.
How Viral Infections Affect the Heart
Experts explain that viruses can harm the heart and vascular system through inflammation, immune overreaction, and blood clot formation. During an infection, the immune system releases inflammatory molecules that may inadvertently weaken blood vessel walls or promote the buildup of fatty deposits. Over time, this persistent inflammation can harden arteries, reduce blood flow, and create conditions ripe for cardiovascular events.
Expert Insights and Prevention Strategies
Dr. Andrew DeFilippis, who chaired the AHA’s writing committee, emphasized that the findings underline a growing public health concern. He noted that preventive measures, especially routine vaccinations like the annual flu shot and updated COVID-19 boosters, play a vital role in reducing heart-related risks. For people living with chronic viral infections such as HIV or HCV, consistent medical treatment and regular cardiovascular monitoring can significantly lower long-term complications.
Public Health Takeaway
The statement reinforces a clear message: protecting against viral infections is also a way to protect the heart. As research continues, medical professionals encourage individuals to prioritize vaccinations, maintain a healthy lifestyle, and manage any ongoing infections with appropriate care.
With heart disease remaining a leading cause of death globally, the study highlights an important truth — preventing viral infections may be one of the most effective ways to prevent heart attacks and strokes in the long run.
