COVID infection increases risk for dangerous heart problems, study finds

In the year after contracting COVID, patients are at an increased risk for developing 20 cardiac problems, a new study found. 

Those problems include stroke, heart attack, myocarditis and irregular heart rhythms, according to the study from Washington University School of Medicine in St. Louis. Study authors estimate COVID infections have led to 3 million cases of heart disease in the U.S. 

Even younger, healthier people were at risk, as were those who were not hospitalized for COVID, according to the study.
