In the study, scientists identified more than 11,000 people who tested positive for COVID-19 in their medical records in 2020 and nearly 3,000 who were hospitalized. They compared them with more than 222,000 people who did not have COVID-19 during that time.

Research shows that people who contracted COVID-19 in 2020, before a vaccine was developed, were twice as likely to develop serious cardiovascular complications — including heart attack, stroke and death — in the three years after infection, compared with people who did not contract the virus.
Hospitalized COVID-19 patients are three times more likely to experience cardiovascular events than those without COVID-19, research shows.
Furthermore, for those who are hospitalized, COVID-19 appears to be a significant risk factor for future heart attacks and strokes, similar to diabetes or peripheral artery disease (PAD).
A study has shown that more than 3.5 million Americans were hospitalized with COVID-19 between May 2020 and April 2021.
Another alarming finding from the latest research shows that the risk of cardiovascular events in people who have been infected with COVID-19 is not only increased but also lasts for a long time.
"The risk doesn't go down, and it may even go up over time," said Dr. Stanley Hazen, a leading cardiologist. "I think that's one of the most surprising findings."
Dr. Patricia Best, a cardiologist at the Mayo Clinic in Rochester, Minnesota, who was not involved in the study, said the finding was surprising and appeared to be unique to COVID-19.
Researchers say they still don't know exactly why COVID-19 has such a lasting impact on the cardiovascular system.
However, it is believed that the coronavirus can penetrate blood vessel walls and damage plaques, increasing the risk of blood clots and leading to dangerous complications such as heart attacks and strokes.
"COVID-19 can cause lasting damage to the vascular system, even after a patient has recovered," said Dr. Hooman Allayee, professor of biochemistry and molecular genetics at the Keck School of Medicine.
Researchers also believe that genes that code for blood type may be linked to an increased risk of heart attack and stroke after COVID-19, but they are still unclear about the specific causes.
“If you have had COVID-19, you need to be particularly careful about reducing your cardiovascular risk,” Dr. Hazen stressed. You should always check your blood pressure, cholesterol, and possibly take an aspirin a day.
