Implantable cardioverter-defibrillator use in catecholaminergic polymorphic ventricular tachycardia: A systematic review.

Background: The implantable cardioverter-defibrillator (ICD) may be associated with a high risk of complications in patients with catecholaminergic polymorphic ventricular tachycardia (CPVT). However, ICDs in this population have not been systematically evaluated.

Objective: The purpose of this study was to characterize the use and outcomes of ICDs in CPVT.

Biological, Psychological, and Social Predictors of Longevity Among Utah Centenarians.

Studies of longevity among centenarians examine biological, psychological, and social factors, yet few consider these components concurrently. This study explores such factors individually and collectively, as they are related to days lived past the age of 100 years. Data from 268 family members of centenarians identified in the State of Utah between 2008 and 2015 were used in negative binomial models predicting number of days lived among the centenarians.
