Physical Activity intervention arm for Physical Activity

The WHISH-2-Prevent Heart Failure (HF) study is an ancillary study to the Women's Health Initiative Strong and Healthy (WHISH) exercise pragmatic trial. The WHISH-2-Prevent HF trial examines the intervention effect of physical activity (PA) on both incident HF and HF burden (recurrent HF and CVD death in those with HF) in a cost effective manner in elderly women. In addition, it will allow a dose-finding analysis to better understand the type, intensity and frequency of PA that leads to a reduced risk and burden of HF. The focus of the parent WHISH trial is on atherosclerotic cardiovascular disease and not heart failure.
