SARS-CoV-2 infection left cardiology with a durable set of clinical problems rather than a single disease. This archive collects writing on the cardiovascular manifestations described during and after acute infection: myocardial injury and troponin elevation of uncertain mechanism, myocarditis and pericarditis, arrhythmia, thrombotic and thromboembolic events, right ventricular strain in severe respiratory failure, and persistent exertional intolerance or dysautonomia in convalescence. The emphasis is diagnostic reasoning and triage under uncertainty rather than protocol. Articles also examine how surges reshaped access to acute cardiac care. Related structured material sits in our acute care course books and the broader course book library.
