  • PURPOSE: Hypertension is an important risk factor for coronary artery disease. However, the impact of hypertension on the outcomes of patients undergoing percutaneous transluminal coronary angioplasty (PTCA) is unknown. Our purpose was to evaluate the association between hypertension and adverse outcomes and repeat cardiac procedures during the 6-month period after PTCA. METHODS: We studied 791 patients who were enrolled in the Routine Versus Selective Exercise Treadmill Testing After Angioplasty (ROSETTA) registry. This registry is a prospective multicenter study examining the use of functional testing after a successful PTCA. RESULTS: We compared 411 hypertensive patients (mean age 60.1 +/- 10 years, 31.1% female) with 380 normotensive patients (mean age 59.1 +/- 12 years, 16.2% female). Patients with hypertension had a higher 6-month rate of composite clinical events (unstable angina, myocardial infarction, death) than did normotensive patients (16.5% vs 10.5%, P =.017). In addition, there was a trend for hypertensive patients to have higher rates of cardiac procedures (angiography, repeat PTCA, coronary artery bypass graft surgery) compared with normotensive patients (19.8% vs 14.9%, P =.074). However, functional testing after PTCA was lower among hypertensive subjects (44.4% vs 54.0%, P =.008). Among the 411 hypertensive patients, a regression analysis showed that several variables were independently associated with increased 6-month adverse event rates, including pre-PTCA Killip class III-IV (odds ratio [OR] 5.7, 95% CI 1.7-19.0), Canadian Cardiovascular Society angina class III-IV (OR 2.1, 95% CI 1.1-4.2), unstable angina as the reason for PTCA (OR 2.3, 95% CI 1.2-4.3), peripheral vascular disease (OR 3.2, 95% CI 1.5-6.4), PTCA of a bypass graft (OR 3.1, 95% CI 1.2-7.6), and calcium antagonist usage at admission for the index PTCA (OR 1.9, 95% CI 1.1-3.4). CONCLUSIONS: During the 6-month period after a successful PTCA, patients with hypertension have significantly higher adverse event rates than do those without hypertension. Several clinical variables may help identify which hypertensive patients are at higher risk for clinical events.
