Sex and Age Characteristics in Acute or Chronic Myocarditis A Descriptive, Multicenter Cohort Study.

Background: Understanding the clinical features of myocarditis in various age groups is required to identify age-specific disease patterns.

Objectives: The objective of this study was to examine differences in sex distribution and clinical outcomes in patients with myocarditis of various ages.

Methods: Patients with acute or chronic myocarditis in 3 centers in Berlin, Germany from 2005 to 2021 and in the United States (National Inpatient Sample) from 2010 to 2019 were included.

Left-ventricular unloading in extracorporeal cardiopulmonary resuscitation due to acute myocardial infarction - A multicenter study.

Background: Guidelines advocate the use of extracorporeal cardio-pulmonary resuscitation with veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in selected patients with cardiac arrest. Effects of concomitant left-ventricular (LV) unloading with Impella® (ECMELLA) remain unclear. This is the first study to investigate whether treatment with ECMELLA was associated with improved outcomes in patients with refractory cardiac arrest caused by acute myocardial infarction (AMI).
