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. Published in Arteriosclerosis, Thrombosis and Vascular Biology , the researchers used UK Biobank data from 10,005 people who had COVID-19 and 217,730 people who did not get infected between February to December 2020. "Worldwide over a billion people have already experienced COVID-19.

The findings reported are not a small effect in a small subgroup," said co-senior study author Stanley Hazen, M.D., Ph.

D., chair of Cardiovascular and Metabolic Sciences in Cleveland Clinic's Lerner Research Institute and co-section head of Preventive Cardiology. "The results included nearly a quarter million people and point to a finding of global health care importance that promises to translate into a rise in cardiovascular disease globally.

" Certain genetic variants are alread.
