ABSTRACT
Background:
Direct stenting without balloon dilatation may reduce procedural costs and duration; and hypothetically; the restenosis rate. This study was designed to compare the in-hospital and long-term outcomes of direct stenting (DS) versus stenting after pre-dilatation (PS) in our routine clinical practice.Methods:
The 1 603 patients treated with stenting for single coronary lesions were enrolled into a prospective registry. Patients with acute myocardial infarction (MI) within the preceding 48 hours; and those with highly calcified lesions; total occlusions; or a lesion in a saphenous graft were excluded. The baseline; angiographic and procedural data; in-hospital outcomes and follow-up data were recorded in our database and analysed with appropriate statistical methods.Results:
Eight hundred and fifty-seven patients (53.5) were treated with DS and 746 (46.5) underwent PS. In the DS group; lesions were shorter in length; larger in diameter and had lower pre-procedural diameter stenosis. Type C and diffuse lesions and drug-eluting stents were found less often (p 0.001). With univariate analysis; dissection and non-Q-wave MI occurred less frequently in this group (0.2 and 0.6vs 3.9 and 2.1; p 0.001 and p ; p = 0.79). With multivariate analysis; direct stenting reduced the risk of dissection (OR = 0.07; 95CI 0.01-0.33; but neither the cumulative endpoint of MACE (OR = 1.1; 95CI = 0.58-2.11; p = 0.7) nor its constructing components were different between the groups.Conclusions:
Direct stenting in the real world has at least similar long-term outcomes in patients treated with stenting after pre-dilatation; and is associated with lower dissection rates
