Table 1.
Relations of Baseline ambulatory and office Heart Rates considered as continuous measures to cardiovascular events in 7600 hypertensive patients. Hazard ratios (95% CI) for a 10 beat/min increment in heart rates or a 10% increment in the night:day ratio are given.
Model | 24-hour HR | Daytime HR | Night-time HR | Night:day ratio* | Office HR |
---|---|---|---|---|---|
Adjusted for age and sex | 1.17 (1.07–1.26) p <0.001 |
1.12 (1.04–1.21) p =0.005 |
1.21 (1.12–1.30) p <0.001 |
1.15 (1.05–1.25) p=0.002 |
1.08 (1.00–1.15) p=0.043 |
Adjusted for age, sex and baseline systolic blood pressure | 1.12 (1.02–1.22) p =0.013 |
1.10 (1.01–1.19) p =0.025 |
1.12 (1.04–1.21) p =0.006 |
1.06 (0.97–1.16) p=0.21† |
1.06 (0.99–1.14) p=0.10 |
Adjusted for age, sex and all risk factors‡ | 1.11 (1.00–1.20) p =0.031 |
1.08 (0.99–1.18) p =0.069 |
1.13 (1.04–1.22) p =0.007 |
1.07 (0.97–1.17) p =0.18† |
1.06 (0.98–1.13) p =0.14 |
HR indicates heart rate.
Adjusted also for average 24-hour heart rate.
Adjusted also for night:day ratio of systolic blood pressure.
Systolic blood pressure, total cholesterol, smoking, diabetes, and serum creatinine.
Diastolic blood pressure, body mass index and alcohol use were found to be non significant in the multivariable Cox models.
