Lean 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 کاملPrediction of mortality in chronic heart failure from peak oxygen consumption adjusted for either body weight or lean tissue.
BACKGROUND Peak oxygen consumption (pVO2) reflects oxygen extraction from the skeletal muscles, but is routinely corrected for body weight. We hypothesized that correcting pVO2 for lean tissue rather than total body weight would improve the prediction of prognosis in patients with chronic heart failure (CHF). METHODS AND RESULTS A total of 272 CHF outpatients (mean age 61 +/- 12 years, New Yo...

متن کاملEffects of cardiovascular drugs on oxygen consumption/oxygen delivery relationship in patients with congestive heart failure.
The oxygen consumption (VO2)/oxygen delivery (DO2) relationship was analyzed in ten patients with severe congestive heart failure (CHF) and normal blood lactate levels. First dobutamine and then enoximone, after a washout period, were administered to each patient to increase cardiac output by at least 15 percent. Similar increases in DO2 were obtained with both drugs: from 285 +/- 46 to 393 +/-...
متن کاملOxygen free radicals and congestive heart failure.
Plasma lipid peroxides (malondialdehyde) and thiols were measured in 45 patients with congestive heart failure and 45 controls. Malondialdehyde concentrations were significantly higher in the patients with congestive heart failure (median 9.0 nmol/ml interquartile range (IQR) 7.9-10.2) than in the controls (median 7.7 nmol/ml (IQR 6.9-9.2)). Plasma thiols were significantly lower in congestive ...
