Objectives

Tests of exercise capacity and quality of life (QOL) questionnaires are used to predict outcomes in heart failure (HF) patients. The short performance physical battery (SPPB) and Ferrans and Power's quality of life index (QLI) are simple, free tests commonly used in geriatric and oncology patients, but data on their use in cardiovascular diseases is limited. We sought to assess their utility in advanced HF patients.

Methods

Ten patients with advanced HF scheduled for ventricular assist device implant were enrolled in this prospective, observational study. Multiple exercise capacity tests including maximal cardiopulmonary stress testing (CPX), 6 minute walk (6MWT), shuttle walk test (SWT), and SPPB were performed. Minnesota Living With Heart Failure (MLWHF) questionnaire, SF-36 v2™, and QLI were administered. Cardiac output was measured non-invasively by acetylene rebreathing. Data were reported …
