Analysis of factors related to short-term prognosis in patients undergoing percutaneous coronary intervention for acute myocardial infarction

Abstract

The present study aimed to investigate the factors related to short-term prognosis in patients undergoing direct percutaneous coronary intervention (PCI) for acute ST-segment elevation myocardial infarction (STEMI). A total of 805 patients were included and divided into a control group and an adverse cardiovascular events group based on the prognosis, to compare risk factors and coronary angiographic characteristics in the two groups. In the adverse events group, the ages, admission blood glucose, uric acid (UA), homocysteine (HCY), creatine kinase (CK) and peak creatine kinase-MB (CKMB) isozyme levels were clearly higher compared with those in the control group, while the levels of total cholesterol (TC), triglycerides (TGs) and low-density lipoprotein (LDL) were lower compared with those in the control group. The incidence of hypertension in females in the adverse events group was markedly higher compared with that in the control group, while the diabetes rate was lower compared with that in the control group. Logistic regression analysis revealed that age, gender, hypertension, diabetes and admission blood glucose, HCY, TC and UA levels were independent risk factors of short-term prognosis in patients undergoing emergency PCI. The majority of the patients in the adverse events group were elderly females with hypertension, a large area of myocardial infarction and increased admission blood glucose, UA and HCY levels, as well as a low diabetes rate and decreased levels of acute-phase TC and LDL.
