Seasonal flu increases risk of heart attack and stroke

Medical experts are warning that the current season of respiratory infections, including influenza, poses significant risks to cardiovascular health. While flu typically presents with fever, cough, and fatigue, it can trigger inflammatory responses that increase the burden on the heart and alter blood clotting activity.

For individuals with underlying conditions such as heart disease, diabetes, or chronic lung disease, these infections can lead to severe complications. The inflammatory process may destabilize arterial plaque, potentially causing blood clots that result in myocardial infarction (heart attack) or stroke. Additionally, fever and infection can increase heart rate and oxygen demand, which, combined with potential pneumonia, may lead to heart failure.

Health professionals emphasize that flu vaccination is a critical preventative measure. Studies indicate that vaccination is associated with a significant reduction in mortality risks for those with cardiovascular diseases, helping to mitigate the inflammatory reactions that trigger acute cardiac events.
