Medical Xpress A history of COVID-19 can double the risk of heart attack, stroke or death according to new research led by Cleveland Clinic and the University of Southern California. The study found that people with any type of COVID-19 infection were twice as likely to have a major cardiac event, such as heart attack, stroke or even death, for up to three years after diagnosis. The risk was significantly higher for patients hospitalized for COVID-19 and more of a determinant than a previous history of heart disease.
Further genetic analysis also revealed individuals with a blood type other than an O (such as A, B or AB) were twice as likely to experience an adverse cardiovascular event after COVID-19 than those with an O-blood type.
