Covid-19 is not just a respiratory infection. Cardiovascular symptoms are seen in both acute and long covid. Katharine Lang reports on what we’ve learnt since the onset of the pandemic Cardiovascular complications from covid-19 have been seen widely since the early days of the pandemic, when a small study in Wuhan reported myocardial injury in several patients.1 Soon after, studies found that up to 30% of those admitted to intensive care units showed myocardial injury.23 “In many respects covid-19 is a vascular disease masquerading as a respiratory one,” says Andy Benest, vascular biologist at the University of Nottingham. Although covid is transmitted through the respiratory system, much of the pathology unfolds in the vascular system, with microvascular damage, thromboinflammation, and dysregulated perfusion underpinning the cardiac, pulmonary, and neurological manifestations of severe disease. “The virus enters through the airways but exerts its systemic effects through the vasculature, the common denominator in the lungs, heart, kidneys, and brain,” Benest tells The BMJ . Cardiovascular complications are relatively common in the acute phase of covid. Studies have found that acute cardiac injury occurred in 6-25% of people admitted to hospital with covid.4 One 2020 study reported that 14.1% of people admitted to hospital with covid experienced some type of cardiovascular complication.5 Early studies suggested that the endothelium …
