Characteristics of COVID-19 Myocarditis With and Without Multisystem Inflammatory Syndrome.

Multisystem inflammatory syndrome (MIS) is a severe complication described in a minority of patients with COVID-19. Myocarditis has been reported in patients with COVID-19, including MIS. In this study, we compared the clinical characteristics and cardiac magnetic resonance (CMR) findings of COVID-19 myocarditis in patients with and without MIS.

Racial differences of heart failure with midrange ejection fraction (HFmrEF): a large urban centre-based retrospective cohort study in the USA.

Objectives: We aimed to study the racial differences in clinical presentations, survival outcomes and outcome predictors among patients with heart failure (HF) with midrange ejection fraction (HFmrEF, EF 40%-49%).

Design: This is a retrospective study.

Setting: Adults with HF diagnosis at Montefiore Medical Center, Bronx, New York between 2008 and 2012, with an inpatient echocardiogram showing left ventricular ejection fraction of 40%-49% were included as HFmrEF population.
