#ST-Segment Elevation in Patients with #Covid-19 — A Case Series

Myocardial injury with ST-segment elevation has been observed in patients with coronavirus disease 2019 (Covid-19). Here, we describe our experience in the initial month of the Covid-19 outbreak in New York City.

Patients with confirmed Covid-19 who had ST-segment elevation on electrocardiography were included in the study from six New York hospitals. Patients with Covid-19 who had nonobstructive disease on coronary angiography or had normal wall motion on echocardiography in the absence of angiography were presumed to have noncoronary myocardial injury..

..A total of 9 patients (50%) underwent coronary angiography; 6 of these patients (67%) had obstructive disease, and 5 (56%) underwent percutaneous coronary intervention (1 after the administration of fibrinolytic agents) (Fig. S3). The relationship among electrocardiographic, echocardiographic, and angiographic findings are summarized in Figure S4. The 8 patients (44%) who received a clinical diagnosis of myocardial infarction had higher median peak troponin and d-dimer levels than the 10 patients (56%) with noncoronary myocardial injury (Fig. S2B and S2C). A total of 13 patients (72%) died in the hospital (4 patients with myocardial infarction and 9 with noncoronary myocardial injury).

In this series of patients with Covid-19 who had ST-segment elevation, there was variability in presentation, a high prevalence of nonobstructive disease, and a poor prognosis. Half the patients underwent coronary angiography, of whom two thirds had obstructive disease. Of note, all 18 patients had elevated d-dimer levels. In contrast, in a previous study involving patients who presented with ST-segment elevation myocardial infarction, 64% had normal d-dimer levels.1 Myocardial injury in patients with Covid-19 could be due to plaque rupture, cytokine storm, hypoxic injury, coronary spasm, microthrombi, or direct endothelial or vascular injury.2 Myocardial interstitial edema has been shown on magnetic resonance imaging in such patients
