Background: This study aimed to identify risk factors associated with the implementation of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in patients with acute myocarditis and to develop a predictive model.

Methods And Results: This retrospective study included 841 patients from 7 hospitals in Korea with biopsy-proven or clinically suspected acute myocarditis. Logistic regression analysis was used to identify the clinical characteristics of patients who required VA-ECMO and to construct a scoring system to predict the implementation of VA-ECMO.

Early unloading and clinical outcomes in patients with fulminant myocarditis undergoing VA-ECMO: results of a multicenter retrospective study.

Introduction And Objectives: Although venoarterial extracorporeal membrane oxygenation (VA-ECMO) provides effective cardiocirculatory support in patients with fulminant myocarditis, the most effective timing of venting is uncertain. We aimed to investigate the benefit of early venting among patients who underwent VA-ECMO for fulminant myocarditis.

Methods: Among 841 patients with acute myocarditis from 7 hospitals in the Republic of Korea, 217 patients with fulminant myocarditis who underwent VA-ECMO were included in this analysis.

Results: The aortic valve was the most commonly affected valve (n = 1,956 [47.

A Case Report for Acute Myopericarditis After NVX-CoV2373 (Novavax) COVID-19 Vaccination.

Post-vaccination myocarditis after administration of the NVX-CoV2373 coronavirus disease 2019 (COVID-19) vaccine has been reported in a limited population. We report the first biopsy-proven case of myopericarditis after administration of second dose of NVX-CoV2373 COVID-19 vaccine (Novavax®) in Korea. A 30-year-old man was referred to emergency department with complaints of chest pain and mild febrile sense for two days.

Association between myocardial ischemia and plaque characteristics in chronic total occlusion.

Background: Myocardial ischemia varies in chronic total occlusion (CTO) despite the occluded artery. We analyzed whether it is associated with the plaque characteristics of the occluded segment.

Methods: We retrospectively enrolled 100 patients with CTO who underwent myocardial perfusion single-photon emission computed tomography (SPECT) and coronary computed tomography angiography (CCTA) within 2 months.

Impact of Cardiac Troponin Elevation on Mortality of Patients with Acute Heart Failure: Insights from the Korea Acute Heart Failure (KorAHF) Registry.

We aimed to conduct the largest study evaluating the impact of cardiac troponin (TnI) status on mid- and long-term mortality in patients admitted for acute heart failure (AHF) as compared between patients with ischemic (IHF) vs. non-ischemic heart failure (non-IHF). Among 5625 patients from the Korea Acute Heart Failure (KorAHF) registry, 4396 eligible patients with TnI measurement were analyzed.

Awareness of cardiovascular disease among Korean women: Results from a nationwide survey.
