Chronic heart failure in the elderly: value of cardiopulmonary exercise testing in risk stratification
Key result
Cardiopulmonary exercise testing parameters, specifically VE/VCO2 slope (P<0.01) and peak VO2 (P<0.05), provided significant independent prognostic information for mortality in elderly patients with CHF.
Why the study?
Does cardiopulmonary exercise testing predict mortality in elderly patients with chronic heart failure?

Implication
May refine mortality risk stratification in elderly CHF; hypothesis-generating and requires prospective validation.

Davies et al. (2000) conducted a cohort in Chronic heart failure (n=50). Cardiopulmonary exercise testing (VE/VCO2 slope and peak VO2) was evaluated on Mortality (p=<0.01). Cardiopulmonary exercise testing parameters, specifically VE/VCO2 slope (P<0.01) and peak VO2 (P<0.05), provided significant independent prognostic information for mortality in elderly patients with CHF.
