TL;DR: Age, gender and/or some lifestyle factors significantly affect heart rate and various components of its variability in the supine position and in response to standing, whereas independent effects of habitual physical activity, smoking habits and body mass index explained no more than 4% of the variance of some measures of heart rate variability.

TL;DR: Atrial fibrillation is associated with a 20% lower peak V˙O2 in patients with chronic heart failure, suggesting that preserved atrial contraction or a regular rhythm, or both, are critical to maintain cardiac output and exercise performance.

TL;DR: It is concluded that the prognostic importance of blood pressure is related to systemic vascular resistance, which provides prognostic information beyond that available from measurements at rest, particularly for the incidence of cardiovascular events.

TL;DR: Respiratory data during submaximal exercise are significant predictors of outcome in patients with chronic heart failure, but their prognostic power is inferior to that of peak VO(2).

TL;DR: The PP-to-SVi ratio was a significant predictor of fatal and nonfatal cardiovascular events and of all-cause mortality after control for age and gender and its predictive power persisted after additional adjustment for mean arterial pressure and heart rate.
