Activity questionnaires; a useful tool in accessing heart failure patients.

Aim: The aim of the study was to correlate the score derived from Specific Activity Questionnaire (SAQ), Left Ventricular Dysfunction 36 (LVD 36) and the Minnesota Living with Heart Failure Questionnaire (LIhFE) with peak oxygen consumption measured during maximal treadmill exercise spirometry in patients with heart failure.

Methods: We prospectively studied 106 patients, average age 47+/-15.5 (mean+/-SD), with symptomatic heart failure.
