Lengthy COVID isn’t the one alternative for the virus to wreak havoc later than anticipated.
Even a light case of COVID can result in an elevated threat of cardiac points like coronary heart failure and stroke for at the very least a yr, in keeping with a March research by Veterans Affairs Division researchers.

And rising knowledge proceed to help these and comparable findings.

Such alterations can result in arrhythmia or coronary heart failure, in keeping with the researchers.
