Comparison of the long-term prognostic value of peak exercise oxygen pulse and peak oxygen uptake in patients with chronic heart failure.
OBJECTIVE To evaluate the ratio of peak oxygen consumption to peak heart rate (peak oxygen pulse) as a predictor of long term prognosis in chronic heart failure. PATIENTS AND SETTING 178 consecutive heart failure patients recruited to the cardiology department of a tertiary referral centre between 1986 and 1993. DESIGN Bicycle ergometry with measurement of respiratory exchange. Mean (SD) fo...
متن کاملThe six-minute walk test predicts peak oxygen uptake and survival in patients with advanced heart failure.
BACKGROUND The 6-min walk test (6'WT) is a simple measure of functional capacity and predicts survival in patients with moderate heart failure (HF). METHODS To assess the role of the 6'WT in the evaluation of patients with advanced HF, 45 patients (age 49 +/- 8 years, mean +/- SD; New York Heart Association class 3.3 +/- 0.6; left ventricular ejection fraction 0.20 +/- 0.06; right ventricular...
متن کامل[Comparison of peak oxygen uptake and VE/VCO2 slope, between children with and without heart failure].
Heart failure is a health problem associated with disability and mortality. Physicians may stratify the risk of adult patients with heart failure using a cardiopulmonary exercise testing. Until now, in childhood this evaluation has been poorly used. The purpose of this study is to compare the peak oxygen uptake and minute ventilation/carbon dioxide production slope among children with heart fai...
متن کاملPeak oxygen uptake in relation to total heart volume discriminates heart failure patients from healthy volunteers and athletes
BACKGROUND An early sign of heart failure (HF) is a decreased cardiac reserve or inability to adequately increase cardiac output during exercise. Under normal circumstances maximal cardiac output is closely related to peak oxygen uptake (VO2peak) which has previously been shown to be closely related to total heart volume (THV). Thus, the aim of this study was to derive a VO2peak/THV ratio and t...
متن کاملCombining peak oxygen consumption and ventilatory efficiency in the prognostic assessment of patients with heart failure.
Exercise ventilatory efficiency (VE/VCO2 slope) and peak oxygen consumption (VO2) are strong mortality predictors in patients with heart failure and we combined these 2 variables' beta coefficients from Cox regression to investigate a new prognostic index. Average follow-up was 3.8+/-1.8 years for 355 patients (72% male, 51+/-10 years). The beta coefficients from peak VO2 (17.3+/-5.0 ml x kg(-1...
