ABSTRACT
UNLABELLED OBJECTIVE To evaluate the predictive value of resting heart rate (RHR) for cardiac and total mortality in a large population of patients referred for coronary angiography with an extended follow-up, stratified in four subpopulations according to gender and age (50th percentile corresponding to 67 years). METHODS:
We studied 3559 subjects (2603 males, age 66 ± 11 years, mean ± SD), obtaining patient data from the Institute electronic databank which saves demographic, clinical, instrumental and follow-up data of patients admitted to our department.RESULTS:
During a mean follow-up period of 35 ± 25 months, 296 (8%) patients died; there were 173 (5%) cardiac deaths. In female patients irrespective of age, RHR (≥ 76 bpm, 75th percentile) did not appear predictive for cardiac death. In females, RHR was predictive for overall mortality after multivariate adjustment only in those aged ≥ 67 years (hazard ratio (HR) 1.7, 95% confidence interval (CI) 1-2.8, p ≤ 0.05). In male patients aged < 67 years, RHR remained as an independent predictive factor for overall mortality at the multivariate analysis (HR 2.5, 95% CI 1.5-4.2, p < 0.001), and as an independent predictor for both cardiac mortality (HR 1.8, 95% CI 1.2-2.7, p < 0.01) and total mortality (HR 1.6, 95% CI 1.2-2.3, p < 0.01) in male patients over 67 years.CONCLUSION:
The current study suggests that the prognostic importance of RHR may differ according to the patient's gender and age, suggesting significant differences in cardiovascular physiopathology between female and male patients.Palavras-chave
