More than six months into the global pandemic, studies have shown that COVID-19 can not only exacerbate existing heart problems, but could also potentially cause new ones.
of people hospitalized with the virus show molecular evidence of new cardiac injury.
“So far the amount of cardiac injury has not been tremendous," said Dr. Sean Wu, cardiologist at Stanford Healthcare--meaning most people who develop these laboratory abnormalities do not necessarily end up having heart problems clinically. He contrasted this with other viruses known to infect the heart, like the Coxsackie B3 virus, which tend to cause problems as a result of inflammation in the heart muscle or “myocarditis” for months to years.
Healthcare workers administer tests at a COVID-19 testing site at United Memorial Medical Center in Houston, on July 9, 2020.The autopsy findings of patients who died from the virus only seemed to deepen the mystery. New York City medical examiners recently reported,, that while their findings were consistent with doctors’ reports of SARS-CoV-2 related lung, kidney and liver damage, they surprisingly found little evidence of physical damage to the heart.
Experts like Mitrani are speculating that long-term heart damage might manifest in unexpected ways, potentially through scar tissue accumulation in the heart, and are highlighting “post-COVID-19 cardiac syndrome” as an important area for future research."We have developed a post-COVID Cardiac Clinic to screen patients for residual heart problems," said Mitrani.
