Heart Failure Symptoms Improve With More Intense Physical Activity.

Background: Little is known about how changes in physical activity (PA) over time may influence symptoms in people with heart failure (HF).

Methods: A secondary analysis was conducted with data from an RCT of an exercise intervention in patients with ICDs (implantable cardioverter defibrillator) and a HF diagnosis ( = 96). Data were collected at baseline and 2 months of PA intervention.

Implementation of a realistic artificial data generator for crash data generation.

In this paper, a framework is outlined to generate realistic artificial data (RAD) as a tool for comparing different models developed for safety analysis. The primary focus of transportation safety analysis is on identifying and quantifying the influence of factors contributing to traffic crash occurrence and its consequences. The current framework of comparing model structures using only observed data has limitations.

Physical function, psychological adjustment, and self-efficacy following sudden cardiac arrest and an initial implantable cardioverter defibrillator (ICD) in a social cognitive theory intervention: secondary analysis of a randomized control trial.

Background: Sudden cardiac arrest (SCA) survivorship results in unique issues in return to physical and psychological function. The purpose of the study was to compare recovery across the first year between SCA survivors and other arrhythmia patients who received a first-time implantable cardioverter defibrillator (ICD) for secondary prevention, participating in a social cognitive theory (SCT) intervention.

Methods: 168 (129 males, 39 females) who received an ICD for secondary prevention (SCA N = 65; other arrhythmia N = 103) were randomized to one of two study conditions: SCT intervention (N = 85) or usual care (N = 83).

The History of Durable Left Ventricular Assist Devices and Comparison of Outcomes: HeartWare, HeartMate II, HeartMate 3, and the Future of Mechanical Circulatory Support.

The utilization of left ventricular assist devices (LVADs) in end-stage heart failure has doubled in the past ten years and is bound to continue to increase. Since the first of these devices was approved in 1994, the technology has changed tremendously, and so has the medical and surgical management of these patients. In this review, we discuss the history of LVADs, evaluating survival and complications over time.

Profiles of partner health linked to a partner-focused intervention following patient initial implantable cardioverter defibrillator (ICD).

This study examined differential responses among partners who participated in a RCT designed to compare two social cognitive theory interventions, one designed for patients only (P-only) and one for patients and their intimate partners (P + P). The interventions were delivered following the patient receiving an initial ICD implant. Partner health outcomes were examined longitudinally from baseline at hospital discharge to 3, 6, and 12 months.
