The six-minute walk test predicts peak oxygen uptake and survival in patients with advanced heart failure.

Could peak oxygen uptake be estimated from proposed equations based on the six-minute walk test in chronic heart failure subjects?

OBJECTIVES To evaluate the agreement between the measured peak oxygen uptake (VO2peak) and the VO2peak estimated by four prediction equations based on the six-minute walk test (6MWT) in chronic heart failure patients. METHOD Thirty-six chronic heart failure patients underwent cardiopulmonary exercise testing and the 6MWT to assess their VO2peak. Four previously published equations that includ...

Assessment of oxygen uptake during the six-minute walk test in patients with heart failure.

Clinical correlates and prognostic significance of six-minute walk test in patients with primary pulmonary hypertension. Comparison with cardiopulmonary exercise testing.

The six-minute walk test is a submaximal exercise test that can be performed even by a patient with heart failure not tolerating maximal exercise testing. To elucidate the clinical significance and prognostic value of the six-minute walk test in patients with primary pulmonary hypertension (PPH), we sought (1) to assess the relation between distance walked during the six-minute walk test and ex...

Atriobiventricular pacing improves exercise capacity in patients with heart failure and intraventricular conduction delay.

OBJECTIVES We sought to assess the efficacy of biventricular pacing with respect to both peak and submaximal measures of exercise in patients with New York Heart Association class III heart failure (HF) and intraventricular conduction delay in a randomized, blinded study. BACKGROUND Submaximal and maximal changes in exercise capacity need evaluating in this patient population with this novel ...

Peak VO(2): a simple yet enduring standard.

In this issue of Circulation, Pardaens et al 1 examine the prognostic value of cardiopulmonary exercise testing in ambulatory patients with heart failure who are screened for cardiac transplantation. The investigators failed to demonstrate any significant advantage of ventilatory data over peak oxygen uptake (V̇O2). Over the past 10 years, several investigators have attempted to refine the use o...
