AIM To assess the association of resting heart rate with allcause and cardiovascular disease(CVD) mortality in the Diabetes Heart Study(DHS).METHODS Out of a total of 1443 participants recruited into the DHS, 1315 participants with type 2 diabetes who were free of atrial fibrillation and supraventricular tachycardia during the baseline exam were included in this analysis. Heart rate was collected from baseline resting electrocardiogram and mortality(all-cause and CVD) was obtained from state and national death registry. Kaplan-Meier(K-M) and Cox proportional hazard analyses were used to assess the association.RESULTS The mean age, body mass index(BMI) and systolic blood pressure(SBP) of the cohort were 61.4 ± 9.2 years, 32.0 ± 6.6 kg/m2, and 139.4 ± 19.4 mmHg respectively. Fiftysix percent were females, 85% were whites, 15% were blacks, 18% were smokers. The mean ± SD heart rate was 69.8(11.9) beats per minute(bpm). After a median follow-up time of 8.5 years(maximum follow-up time is 14.0 years), 258 participants were deceased. In K-M analysis, participants with heart rate above the median had a significantly higher event rate compared with those below the median(log-rank P = 0.0223). A one standard deviation increase in heart rate was associated with allcause mortality in unadjusted(hazard ratio 1.16, 95%CI: 1.03-1.31) and adjusted(hazard ratio 1.20, 95%CI: 1.05-1.37) models. Similar results were obtained with CVD mortality as the outcome of interest.CONCLUSION Heart rate is an independent predictor of all-cause mortality in this population with type 2 diabetes. In this study, a 1-SD increase in heart rate was associated with a 20% increase in risk suggesting that additional prognostic information may be gleaned from this ubiquitously collected vital sign. 展开更多
