Background Myocardial involvement in the course of coronavirus disease 2019 (COVID-19) pneumonia has been reported, though not fully characterized yet. The aim of the present study is to undertake a joint evaluation of hs-Troponin and natriuretic peptides (NP) in patients hospitalized for COVID-19 pneumonia. Methods In this multicenter observational study, we analyzed data from n = 111 patients. Cardiac biomarkers subgroups were identified according to values beyond reference range. Results Increased hs-Troponin and NP were found in 38 and 56% of the cases, respectively. As compared to those with normal cardiac biomarkers, these patients were older, had higher prevalence of cardiovascular diseases (CVD) and had more severe COVID-19 pneumonia by higher CRP and d-dimer and lower PaO2/FIO2. Two-dimensional echocardiography performed in a subset of patients (n = 24) showed significantly reduced left ventricular ejection fraction in patients with elevated NP (p = 0.02), whereas right ventricular systolic function (tricuspid annular plane systolic excursion) was significantly reduced both in patients with high hs-Troponin and NP (p = 0.022 and p = 0.03, respectively). Both hs-Troponin and NP were higher in patients with in-hospital mortality (p = 0.001 and p = 0.002, respectively). On multivariable analysis, independent associations were found of hs-Troponin with age, PaO2/FIO2 and d-dimer (B = 0.419, p = 0.001; B = − 0.212, p = 0.013; and B = 0.179, p = 0.037, respectively) and of NP with age and previous CVD (B = 0.480, p

Myocarditis is difficult to recognize in the early phase particularly when it mimics acute myocardial infarction (STEMI). New strategies to diagnose active myocarditis are needed to avoid unnecessary coronary angiography in such an acute setting. Contrast-enhanced magnetic resonance imaging (MRI) is able to discriminate the small myocardial injuries due to myocarditis from the segmental lesions of ischemic origin.
