NIH Infection from COVID-19 appeared to significantly increase the risk of heart attack, stroke, and death for up to three years among unvaccinated people early in the pandemic when the original SARS-CoV-2 virus strain emerged, according to a National Institutes of Health (NIH)-supported study. The findings, among people with or without heart disease, confirm previous research showing an associated higher risk of cardiovascular events after a COVID-19 infection but are the first to suggest the heightened risk might last up to three years following initial infection, at least among people infected in the first wave of the pandemic.
Compared to people with no COVID-19 history, the study found those who developed COVID-19 early in the pandemic had double the risk for cardiovascular events, while those with severe cases had nearly four times the risk. The findings were published in the journal Arteriosclerosis, Thrombosis, and Vascular Biology.
“This study sheds new light on the potential long-term cardiovascular effects of COVID-19, a still-looming public health threat,” said David Goff, M.D., Ph.D., director for the Division of Cardiovascular Sciences at NIH’s National Heart, Lung, and Blood Institute (NHLBI), which largely funded the study. “These results, especially if confirmed by longer term follow-up, support efforts to identify effective heart disease prevention strategies for patients who’ve had severe COVID-19. But more studies are needed to demonstrate effectiveness.”
