A study led by Cleveland Clinic and the University of Southern California found that a history of COVID-19 can double the risk of heart attack, stroke, or death. People with COVID-19 were twice as likely to have a major cardiac event up to three years after diagnosis, with hospitalized patients at higher risk. Those with non-O blood types were also more likely to have adverse cardiovascular events post-infection. Genetic variants related to heart disease and COVID-19 did not contribute to increased risk, highlighting the importance of blood type. This research emphasizes the need for further investigation into the long-term cardiovascular effects of COVID-19.
