Abstract:
BACKGROUND:Coronary drug-eluting stent implantation is the best treatment for acute ST-segment elevation myocardial infarction, but because of many combined risk factors in elderly patients, the mortality rate is increased with aging. OBJECTIVE:To analyze whether age differences is a significant independent predictor of in-hospital clinical outcomes in patients with acute ST-elevation myocardial infarction treated with domestic rapamycin drug-eluting stent implantation. METHODS:A retrospective analysis was done in 307 patients with first acute ST-elevation myocardial infarction treated with emergent rapamycin drug-eluting stent implantation for primary percutaneous coronary intervention. According to the age, there were three groups: non-elderly group (< 65 years old,n=175), low-elderly group (65-74 years old,n=83), and high-elderly group (≥ 75 years old,n=49). Clinical features, mortality, cardiac events during in-hospital stay were compared among three groups. RESULTS AND CONCLUSION: Compared with the non-elderly group, the proportion of female patients and the history of hypertension were higher in the low-elderly or high-elderly group (P < 0.05). The history of smoking was higher in the non-elderly group than the other groups (P < 0.05). The incidences of Kilip classification≥II, three-lesion or left main coronary artery disease were higher in the high-elderly group than the other groups (P < 0.05). Hemoglobin, total cholesterol, triglycerides, low-density lipoprotein, and cholesterol levels were higher in the non-elderly group than the other groups (P < 0.05). Serum creatinine level, incidence of malignant arrhythmia and incidence of in-hospital cardiac death were increased with aging. Successful reperfusion was higher in the high-elderly group than in the low-elderly or non-elderly group. Rate of acute heart failure and combined cardiovascular events were higher in the high-elderly group than in the low-elderly or non-elderly group (P < 0.05). Multivariate logistic regression analysis show that age is an independent risk factor for in-hospital mortality in patients with acute ST-elevation myocardial infarction treated with rapamycin drug-eluting stent implantation.
