Abstract:
Objective To explore the influence of acute myocardial infarction (AMI) patients with coronary lesions to the ST segment resolution (STR) and clinical prognosis after percutaneous coronary intervention (PCI).Methods 380 patients with AMI were detected twice each hour for the situation of STR,before and after coronary angiography and PCI.According to the STR,the patients were divided into STR (≥ 50％) group and no STR (＜ 50％) group.The relationship between STR and clinical prognosis of hospitalization or follow up were analyzed.Results The STR rate of patients with coronary multivessel disease or proximal lesions after PCI was lower than the rate of patients with coronary single vessel disease or distal lesions (P ＜ 0.05).The incidence rate of major cardiac events and LVEDd during hospitalization in patients with proximal coronary lesions was obviously higher than patients with distal lesions,while LVEF was lower than distal lesions(P ＜0.01).It had no significant differences in LVEF,LVEDd between coronary multivessl disease and single vessel disease during follow up (P ＜ 0.01).Conclusion It has significant relationship between coronary multivessel disease,proximal coronary,STR resolution in patients with AMI after PCI and the prognosis during hospitalization and follow up.
