Maximal oxygen consumption

Oxygen Consumption This can be measured at rest and during exercise on a constant-load bicycle ergometer or a treadmill at a level producing a specified percentage of predicted maximal oxygen consumption. Expired air is collected and measured with a spirometer to determine total expired volume, and samples are analyzed for oxygen and carbon dioxide. [Pg.396]

Fig. 11. The hemodynamic response to exercise is influenced by the p2-Ilel64 polymorphism in patients with heart failure. Exercise-induced changes were significantly lower in patients with Ilel64 for 02, stroke volume (SV), cardiac index (Cl), and systemic vascular resistance (SVR). All changes represent increases by the indicated percentage, except for SVR, which was a decrease. HR, heart rate. / < 0.05 vs Thrl64. V02 is maximal oxygen consumption.

The effect of stavudine-based HAART on mitochondrial respiratory transport chain function in CD4-I- peripheral blood lymphocytes has been studied in HTV-positive patients in Australia [73. CD4-I-lymphocytes isolated from asymptomatic stavudine-treated patients had reduced basal mitochondrial oxygen consumption compared with untreated HIV-infected patients and uninfected controls. Cells from the stavudine-treated patients also had reduced maximal oxygen consumption. There were no significant differences in citrate synthase activities, mitochondrial volume, or mitochondrial DNA copy numbers per cell between the groups. These findings support an association between stavudine and mitochondrial dysfunction and suggest that the alteration in function does not solely result from the... [Pg.457]

For candidate selection several factors have to be assessed low left ventricular (LV) ejection fraction, right ventricular dysfunction, the New York Heart Association (NYHA) functional class, ventricular arrhythmias, measurement of functional capacity with determination of maximal oxygen consumption, hemodynamic measurements, pulmonary capillary resistance and the neurohumoral activation resulting from congestive heart failure (elevated plasma norepinephrine levels) (Aaron-SON et al. 1997 Doval et al. 1996 Gradman and Deedwania 1994 MANCiNietal. 1991 Stevenson et al. 1990). [Pg.12]
