Analyses were performed using time-dependent Cox-models and net reclassification index (NRI).RHR increased with severity of COPD (p<0.001). RHR was associated with both cardiovascular and all-cause mortality across all stages of COPD (p<0.001).Within each stage of COPD, RHR improved the prediction of median life expectancy; the difference between <65 bpm and >85 bpm was 5.5 years in no COPD, 9.8 years in mild, 6.7 years in moderate, and 5.9 years in severe/very severe, (p<0.001). RHR significantly improved risk prediction when added to GOLD stage, (categorical NRI 4.9%, p=0.01; categoryless NRI 23.0%, p<0.0001), or FEV1 in percent of predicted (categorical NRI 7.8%, p=0.002; categoryless NRI 24.1%, p<0.0001).RHR increases with severity of COPD. RHR is a readily available clinical variable that improves risk prediction in patients with COPD above and beyond that of pulmonary function alone. RHR may be a potential target for intervention in COPD. ER -
