The multifarious nature of the damage means treatments for cardiac issues during infection will require tailored approaches.

Images of the players’ hearts showed signs of inflammation consistent with myocarditis, a rare but potentially fatal condition.

There is little evidence that antihypertensive drugs worsen COVID-19, and scientists are instead exploring the idea that such medications—or their downstream effects—may actually alleviate symptoms.
