PURPOSE

To identify predictors of hypertensive blood pressure (BP) responses during Phase II cardiac rehabilitation (CR) patients.

METHODS

Patient demographic data collected consisted of gender, age, cardiac events, and exercise BP responses. For purpose of this study, a systolic blood pressure (SBP) ≥ 190 mmHg and diastolic blood pressure (DBP)≥ 100mmHg were considered elevated. The sample population included 126 males and 74 female phase II CR patients with a mean age of 62 years. Of these patients, 93 had coronary artery bypass graft surgery and 87 had a myocardial infarction (MI) within the last year. Chi-Square analysis and Fishers Exact test were used to analyze the data.

RESULTS

Congestive heart failure (CHF) was the only demographic variable that demonstrated a significant relationship (p < 0.05) to an elevated BP during CR exercise. Additionally, a history of MI showed a strong tendency (p=0.06) toward predicting elevated BP during exercise.

CONCLUSIONS

The present results suggest that monitoring BP on all patients during CR exercise may not be necessary. Contrary to the expected outcome, the CHF patients showed an increase in exercise BP, therefore CR professionals may want to partition patients in Phase II CR exercise programs by MI and CHF variables. Furthermore, time spent performing BPs on patients without MI and CHF may be re-allocated toward additional patient education.
