Comparative Study Between Revascularization and Medical Therapy in Patients With Severe Coronary Artery Lesions Diagnosed by Elective Coronary Angiography / 中国循环杂志

ABSTRACT

Objective: To compare the long term prognosis between revascularization (REV) and medical therapy (MP) in patients with three-vessel disease (3VD) with or without left main (LM) lesion. Methods: A total of 4,875 consecutive patients with elective coronary angiography (CAG) diagnosed 3VD with or without LM lesion treated in our hospital from 2007-01 to 2008-12 were retrospectively studied. The patients were divided into 2 groups MT group,n=705 (14.5%) and REV group,n=4170 (85.5%). The all cause mortality and the rate of revascularization during follow-up period were compared between 2 groups by inverse-probability-weighting approach with propensity score. Results: There were 3962/4875 (81.3%) patients with simple 3VD (right, left anterior descending and left circumlfex coronary arteries) and 913 (18.7%) with 3VD+LM lesion. The in-hospital mortality was similar between 2 groups (OR=0.7, 95% CI 0.3-1.4,P=0.30). With the longest 2-year follow-up study, the adjusted all cause mortality and the rate of revascularization in MT group were both higher than those in REV group (HR=8.3, 95% CI 6.7-11.1,P Conclusion: In real world, the long term prognosis by revascularization treatment was superior to medical treatment in patients with either simple 3 vessel coronary disease or 3 vessel combining LM disease.
