A group of American scientists collected data from 82.6 thousand patients who had myocardial infarction in 2019 or 2020. Most of them have suffered a heart attack at home, at work, or in a public place. Of these, 562 people were infected with the coronavirus.
An analysis of clinical outcomes showed that among those who had a heart attack outside the hospital, 15.2% of patients with COVID-19 and 11.2% of people who were not infected with coronavirus subsequently died. The highest mortality rate was in the group of patients who had a heart attack during hospitalization with any condition: among patients with COVID-19, 78.5% died, compared with 46.1% without coronavirus.
The study authors also found that infected patients were more likely to have cardiac arrest. In addition, people with COVID-19 were significantly less likely to undergo coronary angiography (a procedure to open the lumen of blood vessels) compared to patients without coronavirus.
In addition, patients with heart attack and COVID-19 were generally younger compared to uninfected patients, the scientists said. They noted that they have yet to study the mechanism that increases the risk of death in infected people with heart attacks.
