A number of reports have emerged suggesting these patients may present with signs and symptoms consistent with ST-segment elevation myocardial infarction without coronary ar- tery occlusion. ................................................................................................................................................................................................... Case summary We report an international case series of patients with confirmed COVID-19 infection who presented with sus- pected ST-segment elevation myocardial infarction. Three patients with confirmed COVID-19 presented with elec- trocardiogram criteria for ST-segment elevation myocardial infarction. No patient had obstructive coronary disease at coronary angiography. Post-mortem histology in one case demonstrated myocardial ischaemia in the absence of coronary atherothrombosis or myocarditis. ................................................................................................................................................................................................... Discussion Patients with COVID-19 may present with features consistent with ST-segment elevation myocardial infarction and patent coronary arteries. The prevalence and clinical outcomes of this condition require systematic investigation in consecutive unselected patients. Keywords COVID-19 STEMI Histology Case series Case report � � � � Learning points Patients with coronavirus disease (COVID-19) may present with ST-segment elevation, where urgent coronary angiography should be considered in line with established international guidance. In this series, three patients presenting with ST-segment elevation on the electrocardiogram, which may have been consistent with myocardial infarction, had unobstructed coronary arteries at coronary angiography. Studies of consecutive patients with COVID-19 are necessary to identify the true prevalence of ST-segment elevation and myocardial injury on biomarker testing. * Corresponding author.

The troponin was 7457 ng/L 3 h after the first ECG, and by 12 h had decreased to 5852 ng/L. A transthoracic echocardiogram showed moderate left ventricular systolic dysfunction (Figure 2). The serum troponin con- tinued to fall to 2159 ng/L, and by Day 12, the patient had been weaned from vasopressors. However, his renal function rapidly deteriorated (baseline creatinine 0.89 mg/dL, peak 6.19 mg/dL, nor- mal range 0.84–1.21 mg/dL), such that by Day 13, he was anuric and continuous veno-venous hemofiltration (CVVH) was started. A repeat ECG on Day 15 showed recurrent global ST-elevation pattern (Figure 2). Coronary angiography was undertaken which revealed no luminal stenosis or thrombosis, with preserved TIMI 3 flow in all coronary arteries (Movies 1–3). Left ventriculography revealed mild apical hypokinesis (Supplementary material online, Movie S4). The patient was returned to the intensive care unit (ICU) with a presumptive diagnosis of COVID-19 associated myocarditis, and IV solumedrol and intravenous immunoglobulin (IVIG) were started. His troponin continued to decrease, last measured at 768 ng/L. Video 2 Coronary arteriography cine imaging from Case 1. Despite aggressive supportive measures, the patient became pro- gressively hypotensive and acidotic. His final ECG demonstrated a dramatic shark fin pattern indicative of a diffuse myocardial process (Supplementary material online, Figure S4) and shortly thereafter he went into cardiac arrest (pulseless electrical activity). He was on CVVH with a final potassium recorded at 6.0 mmol/L (normal range 3.5–5 mmol/L). COVID-19 infection was confirmed post-mortem, and an autopsy was performed. Left ventricular sections demon- strated focal eosin uptake indicative of myocardial ischaemia (Figure 3) with no evidence of atherothrombosis or myocarditis. These findings may be in keeping with type 2 myocardial infarction from profound myocardial oxygen supply mismatch in the context of significant refractory hypotension and acidaemia.

The troponin was 7457 ng/L 3 h after the first ECG, and by 12 h had decreased to 5852 ng/L. A transthoracic echocardiogram showed moderate left ventricular systolic dysfunction (Figure 2). The serum troponin con- tinued to fall to 2159 ng/L, and by Day 12, the patient had been weaned from vasopressors. However, his renal function rapidly deteriorated (baseline creatinine 0.89 mg/dL, peak 6.19 mg/dL, nor- mal range 0.84–1.21 mg/dL), such that by Day 13, he was anuric and continuous veno-venous hemofiltration (CVVH) was started. A repeat ECG on Day 15 showed recurrent global ST-elevation pattern (Figure 2). Coronary angiography was undertaken which revealed no luminal stenosis or thrombosis, with preserved TIMI 3 flow in all coronary arteries (Movies 1–3). Left ventriculography revealed mild apical hypokinesis (Supplementary material online, Movie S4). The patient was returned to the intensive care unit (ICU) with a presumptive diagnosis of COVID-19 associated myocarditis, and IV solumedrol and intravenous immunoglobulin (IVIG) were started. His troponin continued to decrease, last measured at 768 ng/L. Video 2 Coronary arteriography cine imaging from Case 1. Despite aggressive supportive measures, the patient became pro- gressively hypotensive and acidotic. His final ECG demonstrated a dramatic shark fin pattern indicative of a diffuse myocardial process (Supplementary material online, Figure S4) and shortly thereafter he went into cardiac arrest (pulseless electrical activity). He was on CVVH with a final potassium recorded at 6.0 mmol/L (normal range 3.5–5 mmol/L). COVID-19 infection was confirmed post-mortem, and an autopsy was performed. Left ventricular sections demon- strated focal eosin uptake indicative of myocardial ischaemia (Figure 3) with no evidence of atherothrombosis or myocarditis. These findings may be in keeping with type 2 myocardial infarction from profound myocardial oxygen supply mismatch in the context of significant refractory hypotension and acidaemia.
