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 کاملPrognostic value of a new cardiopulmonary exercise testing parameter in chronic heart failure: oxygen uptake efficiency at peak exercise - comparison with oxygen uptake efficiency slope.
INTRODUCTION A growing body of evidence shows the prognostic value of oxygen uptake efficiency slope (OUES), a cardiopulmonary exercise test (CPET) parameter derived from the logarithmic relationship between O(2) consumption (VO(2)) and minute ventilation (VE) in patients with chronic heart failure (CHF). OBJECTIVE To evaluate the prognostic value of a new CPET parameter - peak oxygen uptake ...
متن کاملPediatric Exercise Testing: Value and Implications of Peak Oxygen Uptake
Peak oxygen uptake (peak V ˙ O 2 ) measured by clinical exercise testing is the benchmark for aerobic fitness. Aerobic fitness, estimated from maximal treadmill exercise, is a predictor of mortality in adults. Peak V ˙ O 2 was shown to predict longevity in patients aged 7-35 years with cystic fibrosis over 25 years ago. A surge of exercise studies in young adults with congenital heart disease o...
متن کاملPeak exercise oxygen uptake during and following long-duration spaceflight.
This investigation was designed to measure aerobic capacity (V̇o2peak) during and after long-duration International Space Station (ISS) missions. Astronauts (9 males, 5 females: 49 ± 5 yr, 77.2 ± 15.1 kg, 40.6 ± 6.4 ml·kg(-1)·min(-1) [mean ± SD]) performed peak cycle tests ∼90 days before flight, 15 days after launch, every ∼30 days in-flight, and on recovery days 1 (R + 1), R + 10, and R + 30. ...
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...
