Abstract: Objective To analyze the clinical characteristics of non-ST-elevation myocardial infarction (NSTEMI) complicated with acute coronary occlusion(ACO).Methods Totally 77 patients with NSTEMI who had coronary intervention treatment from January to December 2015 in Beijing Anzhen Hospital,Capital Medical University were retrospectively analyzed,including 34 patients complicated with ACO and 43 patients without ACO.All patients had electrocardiography,transthoracic Doppler echocardiography,angiography and revascularization.General clinical data,operation data,coronary lesion location,myocardial ischemia condition,left ventricular systolic function and abnormal myocardial motion were analyzed.Results Average age of patients with ACO was significantly lower than that of patients without ACO[(65 ± 10)years vs (68 ± 10)years] (P ＜ 0.05).Saphenous vein graft lesion rate,coronary artery stenosis degree and bare metal stent implantation rate in patients with ACO were significantly higher than those in patients without ACO[14.7％ (5/34)vs 2.3％ (1/43),100％ (100％,100％) vs 90％ (90％,99％),41.2％ (14/34) vs 7.0％ (3/43)] (P ＜0.05);left main coronary artery lesion rate,left anterior descending branch lesion rate and the duration between acute myocardial infarction (AMI) and percutaneous coronary intervention (PCI) in patients with ACO were significantly lower than those in patients without ACO[0.0％ (0/34) vs 9.3％(4/43),14.7％ (5/34) vs 25.6％ (11/43),120 (64,159) main vs 240 (76,388) main] (P ＜ 0.05).Electrocardiogram results showed that anterior wall myocardial ischemia rate in patients with ACO was significantly lower than that in patients without ACO [(17.6％ (6/34) vs 39.5％ (17/34)] (P ＜ 0.05).Conclusion The identification of NSTEMI complicated with ACO is challenging;NSTEMI patients with ACO are associated with younger age and shorter duration time between AMI attack and PCI compared to patients without ACO,inferior and posterior wall myocardial ischemia are more common.
