Compared with those who were not infected, patients with mild disease had more than three times the risk of myocarditis, an inflammation of the heart muscle, and twice the risk of pulmonary embolism, a blood clot that ends up in a lung artery and blocks blood flow. Still, the increased risk is not trivial. That is a much lower burden than that seen in COVID patients who were hospitalized or admitted to intensive care. When the researchers looked at people with mild COVID specifically, they found that this group had a 39 percent higher risk of developing heart problems, compared with the contemporary control group, or 28 additional cardiovascular problems per 1,000 people in 12 months. The comparison with historical data yielded similar results: the risk of cardiovascular problems in the group that had COVID was 58 percent higher than what was seen in the prepandemic 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. Overall, 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. The researchers compared these patients with two control groups: a contemporary cohort who never became infected and a historical group from before the pandemic. A Serious Public Health ProblemĪl-Aly and his colleagues crunched the numbers on heart and other cardiovascular issues during the first year after infection among 153,760 COVID patients from the national health care databases of the VA.

Even those with mild disease appear to be at a higher risk of heart problems one year after infection, according to one of the largest studies to evaluate the long-term cardiovascular outcomes of COVID. ![]() Two years into the COVID-19 pandemic, it is becoming clear that the cardiovascular impact of SARS-CoV-2, the coronavirus that causes COVID, is not restricted to people who have had severe COVID. As far back as 2004, during the avian flu outbreaks in Asia, he urged public health organizations to consider cardiovascular issues in pandemic preparation plans. “I knew that was going to happen because I’d seen this during influenza epidemics,” he says. Madjid, an associate clinical professor of medicine at the University of California, Los Angeles, expected to see a similar increase in heart complications associated with COVID. This happens because they cause inflammation, which plays a major role in cardiovascular problems.Įven before the first case of COVID-19 had been confirmed in the U.S., interventional cardiologist Mohammad Madjid began looking into the potential effects of coronaviruses on the cardiovascular system. Scientists have long been aware that respiratory infections-such as influenza or certain types of coronaviruses-can trigger heart disease. ![]()
