ABSTRACT
Objective To observe the factors affecting inadequate ST-segment resolution in patients with acute ST-segment elevation myocardial infarction after emergency percutaneous coronary intervention (PCI). Methods The patients with acute ST-segment elevation myocardial infarction undergoing emergency PCI were enrolled for study. According to the ratio of ST-segment resolution, 186 cases were divided into inadequate ST-segment resolution group (54 cases) and relatively adequate ST-segment resolution (132 cases). Clinical data of two groups were compared. The single factor and multiple Logistic regression analysis were performed to determine the factors influencing inadequate ST-segment resolution. Results Pre-infarction angina was protective factor of inadequate ST-segment resolution after emergency PCI (OR=0.361, 95%CI 0.131-0.994, P<0.05). Anterior myocardial infarction, attack-to-balloon time, Killip classification and white blood cell counts were risk factors of inadequate ST-segment resolution (OR=2.389, 95%CI 1.194-4.781;OR=1.655, 95% CI 1.082-2.532; OR=1.319, 95% CI 1.026-1.695; OR=1.184, 95% CI 1.004-1.396, P<0.05). Conclusions Patients with pre-infarction angina could reduce the risk of inadequate ST-segment resolution after PCI. Patients with anterior myocardial infarction,long attack-to-balloon time, Killip classification≥2 and high blood cell counts could increase the risk of inadequate ST-segment resolution, and earlier and more active clinical intervention should be taken.
