title: Health after coronary stenting or balloon angioplasty: results from the Stent Restenosis Study.
abstract: This study was designed to compare health-related quality of life (HRQOL) in patients undergoing coronary stenting or balloon angioplasty in the randomized Stent Restenosis Study. The study sample was drawn from patients at nine U.S. clinical sites of the Stent Restenosis Study, a randomized trial comparing Palmaz-Schatz coronary stent implantation with conventional balloon angioplasty. One hundred ninety-nine consecutive patients were sent surveys 6 to 18 months after enrollment and 160 (80%) were returned. The survey sent to the patients included the Medical Outcomes Study 36-Item Short-Form Health Survey, the Canadian Cardiovascular Society Classification, and the Duke Activity Status Index. Although patients who underwent stenting had less angiographic restenosis and a tendency for fewer ischemic events, there were few differences in HRQOL after a mean of 456 days after randomization. The group that underwent stenting reported significantly less bodily pain than the group that underwent angioplasty (p = 0.02). Otherwise, there were no significant differences in generic or disease-specific measures. In a rating of their overall health, 47% of the group that underwent stenting and 45% of the group that underwent percutaneous transluminal coronary angioplasty reported very good or excellent health. In each group, 60% of the patients reported being symptom free from a cardiovascular perspective. This survey revealed no marked differences in long-term HRQOL between patients who underwent Palmaz-Schatz coronary stenting compared with those who underwent conventional angioplasty.
