Abstract
OBJECTIVES: This study aimed to determine the association of stage B heart failure (SBHF) and its constituent left ventricular (LV) abnormalities with trajectory of exercise capacity over time, and assess whether this association is modified by reversion of these LV abnormalities to normal. BACKGROUND: The LV abnormalities of SBHF may coincide with a reduction in exercise capacity that precedes the overt exercise intolerance of clinical heart failure (HF). Determining the predictive capacity of established and novel SBHF criteria for exercise capacity decline may improve HF risk stratification. METHODS: LV structure/function (echocardiography) and exercise capacity (6-min walk distance [6MWD..
