Abstract
Background: Coronavirus disease 2019 (COVID-19) has emerged as a pandemic and public health crisis of an unprecedent effect. Clinical studies reported an association between COVID-19 and cardiovascular disease, whereas COVID-19 itself can induce myocardial injury, arrhythmia, acute coronary syndrome, and venous thromboembolism.
Case summary: A patient diagnosed via screening coronary computed tomography angiography with non-obstructive coronary artery disease was hospitalized with non-ST elevation myocardial infarction and atrial flutter during a severe respiratory infection episode with SARS-CoV-2. After recovery from the infectious episode, fractional flow reserve-guided elective percutaneous coronary intervention with drug-eluting stent was performed.
Conclusions: COVID-19 intercurrence in a cardiovascular patient with nonobstructive coronary artery disease triggered coronary plaque vulnerabilization with subsequent development of an acute coronary syndrome. SARS-CoV-2 proved to be involved via direct viral tissue involvement and concomitant mechanisms derived from systemic illness in the development of a severe supraventricular arrhythmic event.
