Rate of cardiovascular events up to 8 years after uncomplicated myocarditis: a nationwide cohort study.

Aims: While prognosis of acute myocarditis with uncomplicated presentation is perceived as benign, data on long-term outcomes are scarce. We evaluated rates of myocarditis-associated cardiovascular events after a first-time hospitalization with uncomplicated acute myocarditis in patients without known heart disease.

Methods And Results: In this retrospective nationwide population-based cohort study from 2013 to 2020, hospitalized patients with uncomplicated acute myocarditis but without known heart disease were 1:1 propensity score-matched with surgical controls hospitalized for laparoscopic appendectomy.

Short-Term Outcome After Left Main Interventions in Patients Presenting With Acute Coronary Syndrome.

Objective: To assess the efficacy and safety of coronary left main (LM) disease interventions in patients with acute coronary syndromes (ACS) as compared to those without LM coronary artery disease.

Methods: A total of 2899 patients with ACS, enrolled in the prospective Swiss Program University Medicine ACS (SPUM-ACS) cohort, were included. The primary endpoints of independently adjudicated major adverse cardiovascular and cerebrovascular event (MACCE) and net adverse clinical event (NACE) were determined at 30-day follow-up.
