Your heart needs extra care after Covid: Tips for a healthy recovery
The majority of these occurred in people 65 and older — the age group with the highest risk for cardiovascular complications. But heart-related deaths also increased dramatically in younger adults. In fact, a study found that the sharpest rise in deaths from heart attack during that period occurred in 25- to 44-year-olds.
Some of these cardiovascular-related fatalities may have happened because it was harder to access medical care during the height of the pandemic. But physicians and researchers now have little doubt that COVID-19 itself was a factor. In addition to the complications that can occur during the acute phase of a COVID infection, there appears to be an increased risk of heart attacks, strokes and other problems up to a year after an infection. Experts are now trying to understand why.
«There's a very unique connection between this virus and the cardiovascular system,» said Dr. Susan Cheng, the chair of cardiovascular health and population science at Cedars-Sinai, who led the study on heart attack deaths. «What is that connection? That's the million-dollar question.»
How COVID can immediately affect the heart
Cardiologists' leading theory for how COVID damages the heart and causes cardiovascular events is that it stimulates widespread inflammation.
«We know that inflammation itself increases our cardiovascular risk,» said Dr. Luke Laffin, a cardiologist and co-director of the Center for Blood Pressure Disorders at the Cleveland Clinic. «We know that infectious diseases, particularly severe COVID-19 infections, lead to inflammation. So could that be the mechanism by which there's increased risk? Maybe.»
Part of the immune system's response to infection or injury is to release proteins that cause inflammation
