Comparison of HRs for all-cause mortality between low, moderate and higher sCRF participants at CR entry (n=670)

All-cause mortality (n=206 deaths)Low sCRF* (referent) (n=128)Moderate sCRF HR (95% CI) (n=317)p ValueHigher sCRF† HR (95% CI) (n=225)p Value

  • 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.
