Multi-vessel coronary stenting - Procedural results and late clinical outcomes: A comparison with single-vessel stenting

The purpose of this study was to assess the 1-year clinical outcome of pati ents with multi-vessel coronary artery disease (CAD) who underwent coronary stenting, and to compare the results with single-vessel coronary stenting carried out during the same period. We evaluated the in-hospital and 12-month clinical outcomes [death, Q-wave myocardial infarction (MI) and repeat revascularization rates at one year] in 384 consecutive patients treated with coronary stents in 2 (92% of patie nts) or 3 of the native coronary arteries and compared the outcome to 624 c onsecutive patients undergoing stenting in a single coronary artery between January 1, 1997 and January 31, 1999. The overall procedural success was o btained in 99% of patients with 2- or 3-vessel stenting and 98% of patients with single-vessel stenting. Procedural complications were similar (2.9% v s 2.6%; p = 0.12). During follow-up, target lesion revascularization was 16 % in multi-vessel and 14% in single-vessel stenting (p = 0.38) and repeat r evascularization was also similar for both groups (19% vs. 20%; p = 0.73), There was no difference in death (0.8% vs. 1.3%; p = 0.31) and Q-wave MI (0 .7% vs. 1.4%; p = 0.16) in the 2 groups. Overall cardiac event-free surviva l was similar for both groups (76% vs. 78%; p = 0.54). Multi-vessel stentin g in carefully selected patients in our experience had a high procedural su ccess with very low complication rates. The one-year clinical outcomes were acceptable and were similar to the results of single-vessel stenting.
