Table 5.
Cardiovascular Events in Patients With Low or High RHI
| All High‐Risk Patients | High RHI Group (n=267) | Low RHI Group (n=261) | P Value |
|---|---|---|---|
| No. (% [95% CI]) | No. (% [95% CI]) | ||
| Total cardiovascular events | 22 (8.2 [4.9 to 11.5]) | 83 (31.8 [26.2 to 37.5]) | <0.0001 |
| Cardiovascular death | 0 (0 [0 to 0]) | 1 (0.4 [−0.4 to 1.1]) | 0.296 |
| AMI or unstable angina | 1 (0.4 [−0.4 to 1.1]) | 28 (10.7 [7.0 to 14.5]) | <0.0001 |
| Heart failure | 2 (0.7 [−0.3 to 1.8]) | 13 (5.0 [2.3 to 7.6]) | 0.0036 |
| Coronary revascularization | 14 (5.2 [2.6 to 7.9]) | 29 (11.1 [7.3 to 14.9]) | 0.0089 |
| Aortic disease or PAD | 4 (1.5 [0.0 to 3.0]) | 6 (2.3 [0.5 to 4.1]) | 0.384 |
| Stroke | 1 (0.4 [−0.4 to 1.1]) | 6 (2.3 [0.5 to 4.1]) | 0.048 |
Significance was assessed by the log rank test. AMI indicates acute myocardial infarction; CI, confidence interval; PAD, peripheral arterial disease; RHI, reactive hyperemia‐peripheral arterial tonometry index.
