Cox Regression Analysis Showing the Risk of Cardiovascular Events for Abnormal ppVo2peak
| Covariates (n = 58)∗ | Hazard Ratio (95% Confidence Interval) | P Value |
|---|---|---|
| Unadjusted | ||
| Abnormal (≤85%) ppVo2peak | 3.48 (1.24-9.77) | 0.018 |
| Adjusted for confounders | ||
| Abnormal (≤85%) ppVo2peak | 6.37 (2.06-19.8) | 0.001 |
| Hypertension† | 15.1 (4.39-51.9) | <0.001 |
| Overweight or obesity | 0.60 (0.20-1.83) | 0.371 |
CPET = cardiopulmonary exercise testing; ppVo2peak = percent-predicted peak Vo2.
∗
Of the 64 patients, 6 were excluded because of the occurrence of a cardiovascular event before their first CPET.
†
Patients with a history of antihypertensive medication use were also included.
