COVID-19 and cardiovascular concerns: An evolving story

Physicians’ understanding of how a COVID-19 infection affects the heart is still evolving. More definitive answers require long-term, randomized clinical trials that control for different factors (including varied medical histories and medication use) to study how COVID-19—and possible therapies—affect people who have or are at risk for heart disease. Like other infectious organisms, SARS-CoV-2 (the virus that causes COVID-19) can increase the risk of blood clots and may damage the heart, but the danger is less common than initial reports suggested.
