COVID-19 survivors show biological aging acceleration and early cardiovascular risk

This comprehensive review synthesizes emerging evidence that COVID-19 infection may trigger lasting biological changes consistent with accelerated aging, particularly affecting cardiovascular health in people who were previously young or middle-aged. The authors examine multiple mechanisms including persistent inflammation, endothelial dysfunction, mitochondrial damage, and cellular senescence triggered by SARS-CoV-2 infection. Post-COVID syndrome ('long COVID') shares features with biological aging: chronic fatigue, cognitive impairment, and elevated cardiovascular risk. Concerningly, even younger survivors without severe acute illness show increased rates of heart attacks, strokes, and other cardiovascular events in the months and years following infection. The review connects these observations to measurable biomarkers of aging and proposes that interventions targeting these pathways - including senolytics and mitochondrial support - might help. Given that billions globally have been infected, understanding whether COVID-19 meaningfully accelerates biological aging trajectories has massive public health implications. If confirmed in longitudinal studies, it could mean population-level aging acceleration and would make therapies that reverse or slow biological aging even more urgent priorities.
