Myocardial Injury by COVID-19 Infection Assessed by Cardiovascular Magnetic Resonance Imaging　― A Prospective Multicenter Study ―

Abstract

ated with COVID-19 is considered a rare but serious cardiovascular complication, 4,5 but information on its prevalence and pathogenesis is limited. Although, blood troponin 6,7 and echocardiography 8-10 have been used to evaluate acute cardiovascular complications, neither test is ideal, in terms of sensitivity and specificity, for detecting myocardial injury.Cardiovascular magnetic resonance (CMR) is an imag-T he COVID-19 pandemic was a considerable public health crisis. 1 Initially identified as a cluster of cases of pneumonia, it swiftly became apparent that COVID-19 was more than a mere respiratory ailment. The clinical trajectory of COVID-19 is frequently complicated by cardiovascular conditions, encompassing both venous and arterial thrombosis, electrophysiological anomalies, and myocardial injury. 2,3 Acute myocardial injury associ-

Prevalence of Cardiac Involvement in Japanese Patients Who Have Recovered From COVID-19

“…5,6 In this issue of the Journal, Kato et al present new data regarding the prevalence of myocardial injury using cardiovascular magnetic resonance (CMR) in older COVID-19 Japanese patients suspected to have myocardial injury. 7 The authors conducted a prospective multicenter study of 31 COVID-19 patients who underwent CMR 3 months after acute onset discharge. CMR imaging was performed using 1.5-or 3-T magnetic resonance scanners, and the CMR protocol includes cine, T2-weighted images (T2WI), and late gadolinium enhancement (LGE).…”
