Comparative StudyIncreased heart failure risk in normal-weight people with metabolic syndrome compared with metabolically healthy obese individuals.
The purpose of this study was to assess whether the metabolically healthy obese phenotype is associated with lower heart failure (HF) risk compared with normal-weight individuals with metabolic syndrome (MetS). ⋯ In contrast to normal weight insulin-resistant individuals, metabolically healthy obese individuals show decreased HF risk in a 6-year follow-up study.

Comparative StudyActivation and entrainment mapping of hemodynamically unstable ventricular tachycardia using a percutaneous left ventricular assist device.
Our goal was to investigate the effects of percutaneous left ventricular assist device (pLVAD) support during catheter ablation of unstable ventricular tachycardia (VT). ⋯ In patients with scar-related VT undergoing catheter ablation, pLVAD support was able to safely maintain end-organ perfusion despite extended periods of hemodynamically unstable VT. Randomized studies are necessary to determine whether this enhanced ability to perform entrainment and activation mapping will translate into a higher rate of clinical success.

Sudden death in young adults: an autopsy-based series of a population undergoing active surveillance.
The purpose of this study was to define the incidence and characterization of cardiovascular cause of sudden death in the young. ⋯ Prevention of sudden death in the young adult should focus on evaluation for causes known to be associated with SUD (e.g., primary arrhythmia) among persons <35 years of age, with an emphasis on atherosclerotic coronary disease in those ≥ 35 years of age.
