Comparison of the long term prognostic value of peak exercise oxygen pulse and peak oxygen uptake in patients with chronic heart failure

摘要

Conclusions-Peak oxygen pulse has lower prognostic value than peak oxygen consumption, especially when the latter is indexed to predicted values. Objective-To evaluate the ratio of peak Oxygen consumption to peak heart rate (peak oxygen pulse) as a predictor of long term prognosis in chronic heart failure. Patients and setting-178 consecutive Heart failure patients recruited to the car- Diology department of a tertiary referral Centre between 1986 and 1993. Design-Bicycle ergometry with measure- Ment of respiratory exchange. Mean (SD) Follow up was 32 (25) months.
