Multicenter Study
Phenotyping Heart Failure According to the Longitudinal Ejection Fraction Change: Myocardial Strain, Predictors, and Outcomes.
Background Many patients with heart failure (HF) experience changes in left ventricular ejection fraction (LVEF) during follow-up. We sought to evaluate the predictors and outcomes of different HF phenotypes according to longitudinal changes in EF. Methods and Results A total of 2104 patients with acute HF underwent echocardiography at baseline and follow-up. ⋯ Each HF phenotype according to longitudinal LVEF changes has a distinct prognosis. Global longitudinal strain can be used to predict the HF phenotype. REGISTRATION: URL: https://www.clinicaltrials.gov; Unique identifier: NCT03513653.

Background Evidence suggests familial aggregation and intergenerational associations for individual cardiovascular health (CVH) metrics. Over a 53-year life course, we examined trends and association of CVH between parents and their offspring at similar mean ages. Methods and Results We conducted a series of cross-sectional analyses of the FHS (Framingham Heart Study). ⋯ Conclusions Parental CVH was positively associated with offspring CVH. However, intergenerational CVH gains from declining smoking rates, cholesterol, and blood pressure were offset by rising offspring obesity and elevated glucose levels. This suggests an intergenerational phenotypic shift of risk factors and the need for a family-centered approach to cardiovascular care.

Meta Analysis
Early Administration of Adrenaline for Out-of-Hospital Cardiac Arrest: A Systematic Review and Meta-Analysis.
Background The use of adrenaline in out-of-hospital cardiac arrest (OHCA) patients is still controversial. This study aimed to determine the effects of early pre-hospital adrenaline administration in OHCA patients. Methods and Results PubMed, EMBASE, Google Scholar, and the Cochrane Library database were searched from study inception to February 2019 to identify studies that reported OHCA patients who received adrenaline. ⋯ Patients with shockable rhythm cardiac arrest had a significantly higher rate of survival to discharge (RR, 5.86; 95% CI, 4.25-8.07; P<0.001) and more favorable neurological outcomes (RR, 5.10; 95% CI, 2.90-8.97; P<0.001) than non-shockable rhythm cardiac arrest patients. Conclusions Early pre-hospital administration of adrenaline to OHCA patients might increase the survival to discharge, return of spontaneous circulation, and favorable neurological outcomes.
