Long stenting in native coronary arteries: relation between vessel size and outcome

Cathet Cardiovasc Diagn. 1998 Jun;44(2):170-4. doi: 10.1002/(sici)1097-0304(199806)44:2<170::aid-ccd9>3.0.co;2-3.

Abstract

Procedural and 6-mo clinical outcomes were evaluated in 34 consecutive patients who had stenting (<40 mm) of a long segment of coronary artery. Procedural success was achieved in 32 (96%) patients. Before stenting, 32 (96%) patients had Canadian Cardiovascular Society Class 3 or 4 angina compared to 7 (21%) at 6-mo follow-up (P<0.001). Eleven patients (32%) suffered either acute/subacute stent thrombosis (n=4) or restenosis (n=7). On logistic regression distal reference diameter <2.5 mm (odds ratio 26, P<0.01) and previous cardiac intervention (odds ratio 9.0, P<0.01) were independent predictors of a major adverse event during follow-up. There was no significant association between outcome and indication for stenting, type of stent, or use of ticlopidine and aspirin. These results indicate that distal vessel diameter <2.5 mm is a powerful predictor of subacute thrombosis or restenosis after long coronary artery stenting.
