All-cause mortality (n=206 deaths) | Low sCRF* (referent) (n=128) | Moderate sCRF HR (95% CI) (n=317) | p Value | Higher sCRF† HR (95% CI) (n=225) | p Value |
---|---|---|---|---|---|
Model 1: unadjusted | 1.00 | 0.50 (0.37 to 0.68) | <0.0005 | 0.25 (0.17 to 0.37) | <0.0005 |
Model 2: adjusted for age | 1.00 | 0.55 (0.40 to 0.75) | <0.0005 | 0.35 (0.23 to 0.53) | <0.0005 |
Model 3: adjusted for covariates | 1.00 | 0.59 (0.42 to 0.83) | 0.002 | 0.40 (0.25 to 0.64) | <0.0005 |
Model 3 covariates were as follows: age; ACE-inhibitor, statin, diuretic, antiplatelet therapy use; diabetes, other CVD, waist circumference, TC/HDL ratio, date of CR entry, marital status, physical inactivity, resting heart rate, exercise test mode and negative exercise test (ECG).
*Entry sCRF level <6 METs (men) and <5 METs (women) at CR entry.
†Entry sCRF level ≥8 METs (men) and ≥7 METs (women) at CR entry.
CVD, cardio vascular disease; CR, cardiac rehabilitation; METs, metabolic equivalents; TC/HDL, total cholesterol high-density lipoprotein ratio; sCRF, submaximal cardiorespiratory fitness.
