Abstract

Abstract:

Objective The clinical features and prognosis of patients with isolated left main coronary artery (LMCA) were analyzed retrospectively. Methods Thirty consecutive patients with isolated LMCA stenosis were selected and divided into two groups: open lesion group (n=21) and non-open lesion group (n=9).The follow-up endpoint was major adverse cardiac or cerebrovascular event(MACCE), which was defined as all-cause death and cardiovascular and cerebrovascular events requiring hospitalization.Results Most of the 30 patients with isolated LMCA were treated with percutaneous coronary intervention (PCI)(25/30, 83.3%), only 2 patients received coronary artery bypass grafting, and the remaining 3 patients only received medication. During the median follow-up period of 37.0 months, the incidence of MACCE was 23.3%(7/30), including 4 deaths.Compared with non-open lesion group, open lesion group had more female patients (47.6% vs 0%, P=0.013), younger age (57.8±10.9 vs 66.0±7.8, P=0.050), and significantly lower MACCE incidence (9.5% vs 55.6%, P=0.014).Conclusion PCI is an effective and safe treatment for isolated LMCA stenosis, and the long-term MACCE incidence in open lesion group was lower than that in non-open lesion group.

Key words: left main coronary artery stenosis, percutaneous coronary intervention, prognosis
