Covid-19 could be a powerful risk factor for heart attacks and strokes for as long as three years after an infection, a large new study suggests.
The study was published Wednesday in the medical journal Atherosclerosis, Thrombosis, and Vascular Biology. It relied on medical records from roughly a quarter of a million people who were enrolled in a large database called the UK Biobank.

Even mild cases carry risk, but COVID most frequently wallops people after severe cases, especially when hospitalized. Of the nearly 300,000 Canadians hospitalized so far, over half likely have — or will — suffer life-changing health consequences, sometimes years after having recovered from the acute illness. These risks climb with repeated infections.
Hospitalizations and deaths from COVID-19 are often delayed. Like high blood pressure, SARS CoV-2 can gradually damage the inner lining of blood vessels. This by itself, is painless. While it happens to people following mild cases of COVID, it’s far more likely after severe ones, especially after hospitalization. This doubles the downstream risk of having a heart attack, stroke or blood clot in the lung. It triples the risk of developing an abnormal heart rhythm, including atrial fibrillation.
Comments closedEven as national institutions struggle to coordinate meaningful trials for possible long COVID treatments, researchers continue to tally the damage. New findings suggest that the disease’s reach isn’t merely long—it’s still growing.
Three years after their initial bouts with COVID-19, patients who’d once been hospitalized with the virus remained at “significantly elevated” risk of death or worsening health from long COVID complications, according to a paper published May 30 in Nature Medicine.
Even among those whose initial cases didn’t require a hospital stay, the threat of long COVID and several of its associated issues remained real, the researchers found. And cumulatively, at three years, long COVID results in 91 disability-adjusted life years (DALY) per 1,000 people—DALYs being a measure of years lost to poor health or premature death. That is a higher incidence than either heart disease or cancer.
Comments closedThe severity of the infection doesn’t seem to make a difference. These complications can occur even in people who have very mild symptoms. The big surprise is how much this can affect younger people. Studies are showing that even young, active people can experience heightened risk of these complications.
High blood pressure, high cholesterol, diabetes, obesity: These are some of the well-known risk factors that can put people at heightened risk for heart attack and stroke.
Now some health experts say COVID-19 should be added to that list.
Comments closedResearchers increasingly find that the effects of infection by SARS-CoV-2 extend to the cardiovascular system.
Comments closedCOVID-19 is known to increase the risk of heart attack and stroke. The intense inflammation that occurs throughout the body in severe cases likely contributes to this increased risk. But it’s not clear whether SARS-CoV-2, the virus that causes COVID-19, also affects blood vessels directly.
To find out, an NIH-funded research team, led by Dr. Chiara Giannarelli at New York University School of Medicine, analyzed coronary artery tissue samples from eight people who died of COVID-19 between May 2020 and May 2021. Results appeared in Nature Cardiovascular Research on September 28, 2023.
Comments closedSARS-CoV-2 can directly infect the arteries of the heart, inflaming the fatty plaque inside and raising the risk of heart attack and stroke, suggests a small study published yesterday in Nature Cardiovascular Research.
Comments closedNew figures show there was a surge in deaths from heart failure, lung disease and strokes in New Brunswick in 2021, as deaths from COVID-19 were also multiplying.
Comments closedHeart attack-caused deaths rose during every virus surge. Worse, young people aren’t supposed to have heart attacks but Cheng’s research documented a nearly 30% increase in heart attack deaths among 25- to 44-year-olds in the pandemic’s first two years.
Comments closedInfection control epidemiologist Colin Furness said rising deaths from heart attacks and strokes increasingly appear to be related to damage caused by COVID-19 infections.
Comments closedOverall, the risk of any heart complication over the course of one year was 63 percent higher in people who had gotten COVID compared with those in the contemporary control group. At the end of a year, there were 45 additional cardiovascular events—such as stroke or heart failure—per 1,000 people among those who tested positive for COVID.
