Myocardial injury is frequently detected in coronavirus disease 2019 (COVID-19) patients. However, up to one-third of COVID-19 patients showing ST-segment elevation on the electrocardiogram have angiographically normal coronary arteries. We present a case of an acute coronary syndrome due to a coronary spasm in a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) patient. This pathophysiological mechanism was clearly demonstrated by intracoronary imaging techniques (optical coherence tomography) and invasive vasospasm test.

Background: Chronic coronary syndromes (CCS) occur commonly in the absence of flow-limiting epicardial coronary stenoses. Ischemia or angina with no obstructive coronary arteries (INOCA/ANOCA) may be caused by coronary microvascular disease, coronary artery spasm, myocardial bridging, diffuse atherosclerosis, or a combination of disorders.
Methods & Results: We highlight the new recommendations in the 2024 European Society of Cardiology (ESC) guidelines on CCS relevant to the diagnosis and management of INOCA/ANOCA.
Background: A coronary function test (CFT) is the recommended diagnostic test to identify coronary vasomotor dysfunction as a cause of symptoms in patients with angina and nonobstructive coronary arteries (ANOCA). Acetylcholine is the commonly used pharmacological agent for spasm provocation. We aimed to investigate an association between severity of symptoms and provocative acetylcholine dose.

Background: Acute myocardial infarction during pregnancy is a rare condition with an incidence of 1 to 10 per 100,000 deliveries. ST-elevation myocardial infarction (STEMI) is dominating the clinical presentation. It is estimated that 29% of the patients had normal coronary arteries, and hyperthyroidism may be associated with coronary vasospasm.

Background: Recently it has been suggested that coronary microvascular dysfunction (CMD) may explain the high false-positive rate of exercise electrocardiographic stress testing (EST). However, patients with angina but non-obstructive coronary artery disease (ANOCA) present with a broader spectrum of coronary vasomotor dysfunction (CVDys), namely coronary artery spasm (CAS), CMD or a combination of both. We aim to investigate the diagnostic value of EST for the entire CVDys spectrum.

Coronary vasospasm involves constriction of the coronary arteries and has been described after manipulation of the coronary arteries (ie, after stenting or bypass grafting). This report details the case of a 57-year-old man who presented with an endoleak after thoracic endovascular aortic repair. He underwent a frozen elephant trunk procedure and postoperatively had diffuse coronary vasospasm, demonstrated on pre- and post-vasospasm cardiac catheterization.
