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 کاملLean tissue adjusted peak oxygen consumption in congestive heart failure.
We disagree with the comments made by Dr. F. James Brennan that major events were underreported in our recent Journal article (1). Although we used a composite end point that included death, myocardial infarction, cerebrovascular accident and myocardial revascularization, we also separately reported mortality, myocardial infarction, repeat revascularization procedures and stroke (1). For exampl...
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 کاملResting muscle sympathetic nerve activity and peak oxygen uptake in heart failure and normal subjects.
AIMS Exercise intolerance and increased efferent vasoconstrictor traffic to muscle are two characteristics of heart failure that have not been explicitly linked. We tested the hypothesis that peak oxygen consumption is inversely related to resting muscle sympathetic nerve activity in heart failure. METHODS AND RESULTS We recorded peroneal muscle sympathetic nerve activity in 17 treated heart ...
