Prevalence and Impact of Myocardial Injury in Patients Hospitalized With COVID-19 Infection.
The degree of myocardial injury, as reflected by troponin elevation, and associated outcomes among U.S. hospitalized patients with coronavirus disease-2019 (COVID-19) are unknown. ⋯ Myocardial injury is prevalent among patients hospitalized with COVID-19; however, troponin concentrations were generally present at low levels. Patients with CVD are more likely to have myocardial injury than patients without CVD. Troponin elevation among patients hospitalized with COVID-19 is associated with higher risk of mortality.

Multicenter StudyTranscatheter Valve-in-Valve Aortic Valve Replacement as an Alternative to Surgical Re-Replacement.
Valve-in-valve (VIV) transcatheter aortic valve replacement (TAVR) and redo surgical aortic valve replacement (SAVR) represent the 2 treatments for aortic bioprosthesis failure. Clinical comparison of both therapies remains limited by the number of patients analyzed. ⋯ VIV TAVR was observed to be associated with better short-term outcomes than redo SAVR. Major cardiovascular outcomes were not different between the 2 treatments during long-term follow-up.

Multicenter Study Observational StudySmartphone Activation of Citizen Responders to Facilitate Defibrillation in Out-of-Hospital Cardiac Arrest.
Dispatching citizen responders through a smartphone application (app) holds the potential to increase bystander cardiopulmonary resuscitation (CPR) and defibrillation in out-of-hospital cardiac arrest (OHCA). ⋯ Arrival of app-dispatched citizen responders before EMS was associated with increased odds for bystander CPR and a more than 3-fold increase in odds for bystander defibrillation.
