Abstract:
Objective:To compare and study coronary artery lesions characteristics of patients with non -ST -seg‐ment elevation acute myocardial infarction (NSTEMI) .Methods :A total of 66 patients diagnosed as acute NSTEMI were enrolled as NSTEMI group ,meanwhile 74 patients with unstable angina pectoris (UAP) were regarded as UAP group and 76 patients with acute ST -segment elevation myocardial infarction (STEMI ) were regarded as STEMI group .All patients received coronary angiography (CAG) and optical coherence tomography (OCT) examination . Coronary artery lesions characteristics were compared among three groups .Results:Pairwise comparison showed , that occlusion lesion (33.3% ) and serious stenosis (70% ~94% ) lesion (34.8% ) in NSTEMI group were signifi‐cantly more than those of UAP group (14.9% ,8.1% ) respectively;the occlusion lesion and serious stenosis lesion of STEMI group were no significant difference compared with those of STEMI group , P>0.05 all;type C lesion 43.9% of NSTEMI group was significantly more than that of UAP group (27.0% ) and of STEMI group (31.6% ) respectively ( P<0.05 all);vulnerable plaque of NSTEMI group (56.1% ) was significantly more than that of UAP group (23.0% ,P<0.01) ,but was no significant difference compared with STEMI group (56.6% ,P> 0.05). Conclusion :Serious stenosis lesion ,type C lesion and vulnerable plaque of NSTEMI group are significantly more than those of UAP group ;in NSTEMI group , type C lesion is significantly more than ,and occlusion lesion occlusion le‐sion significantly less than that of STEMI group .
