Clinical and angiographic follow-up after coronary angioplasty in patients with two-vessel disease: influence of completeness and adequacy of revascularization on long-term outcome.

Abstract To assess the influence of the degree of revascularization on long-term results with angioplasty in multivessel disease, 151 consecutive patients with double-vessel disease and successful angioplasty in at least one vessel were prospectively followed up for a mean of 14 months (range 6 to 30 months) with clinical evaluation, an exercise stress test, and routine angiography. Patients were divided into three groups according to completeness and adequacy of revascularization: group 1—complete revascularization (no residual stenosis ≥70%, 51 patients); group 2—incomplete but functionally adequate revascularization (residual stenosis ≥70% in a vessel p = NS). Recurrence of angina was lower in group 1 (13 of 51 or 26%) and group 2 (16 of 56 or 28%) compared with group 3 (23 of 45 or 51%, p p p p
