Worrying scientific results about the risk of corona infection on the heart

Even in “mild” cases of the Corona virus, the risk of developing heart disease after it is clearly high, according to a study whose results were published by the scientific website Nature, on Sunday.

The study, which included tens of thousands of infected people, shows a "huge and long-term" increase in the risk of heart and circulatory diseases, including heart attack and stroke, after infection with Covid-19.

The researchers found that rates of many conditions, such as heart failure and stroke, were significantly higher in people who had recovered from COVID-19 than in similar people who did not have the disease.

What's more, the risk was high even for those under 65 who lacked risk factors, such as obesity or diabetes.

"It doesn't matter if you're young or old, and it doesn't matter if you smoke, or You didn't smoke, the danger was there."

Al-Ali and colleagues based their research on an extensive database of health records sponsored by the US Department of Veterans Affairs.

The researchers compared information on more than 150,000 veterans who survived at least 30 days after contracting COVID-19 with two groups of uninfected people, including one recorded before the onset of COVID-19.

And people who recovered from COVID-19 showed significant increases in the 20 heart problems reported over the year following infection.

For example, those affected were 52% more likely to have a stroke, and their risk of heart failure increased by 72%.

Injuries that led to hospitalization increased the likelihood of future cardiovascular complications, but even people who avoided hospitalization were at risk.

"I am actually surprised by these findings that cardiovascular complications of COVID can persist for such a long time," Hossain Ardhali, a cardiologist at Northwestern University in Chicago, Illinois, wrote in an email to the journal Nature.

"It is important that those who have not been vaccinated get the vaccine immediately," he added.

 Researchers agree that health care providers around the world must be prepared to address the increase in cardiovascular disease, but with the number of cases of the virus rising, some fear that health authorities will delay preparing for the effects of the epidemic for too long.
