Resting 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 ...
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 کاملRelation between cardiac dimensions and peak oxygen uptake
BACKGROUND Long term endurance training is known to increase peak oxygen uptake (VO2peak) and induce morphological changes of the heart such as increased left ventricular mass (LVM). However, the relationship between and the total heart volume (THV), considering both the left and right ventricular dimensions in both males and females, is not completely described. Therefore, the aim of this stud...
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 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...
