急性心肌梗死患者1个月内预后的临床相关因素分析

Analysis on Clinical Related Factors of the Prognosis of Acute Myocardial Infarction Within aMonth

【目的】明确影响急性心肌梗死预后的独立危险因素。【方法】纳入2006年6月到2011年6月期间在广元市中心医院出院和死亡病历中诊断为急性心肌梗死的408例患者的病历资料，设计调查量表及资料提取表格。根据资料中急性心肌梗死患者发病后1个月内的死亡情况，将患者资料分为已死亡患者组和未死亡患者组进行对比分析，明确年龄、血压、血脂等是否为影响急性心肌梗死预后的独立危险因素。【结果】年龄增加、血压升高、血糖增加、血脂升高、曾有脑卒中事件可增加急性心肌梗死患者的病死率，而心肌酶及血红蛋白含量降低也有同等效应。【结论】通过回归分析可知，血压、年龄、甘油三脂、胆固醇、吸烟是影响急性心肌梗死患者入院后1个月内死亡的重要独立预测因素，其中年龄因素最为重要。

[Objective] To clarify the independent risk factors affecting the prognosis of acute myocardial infarction. [Methods] Case records of 408 patients diagnosed as acute myocardial infarction in central hospital of Guangyuan city from June 2006 to June 2011 were enrolled in the study. Investigation scale and data extraction table were designed. According to the death status of acute myocardial infarction within a month after disease onset, the documents of patients were divid- ed into dead patient group and non-dead patient group, and compared between tow groups. The independent risk factors such as age, blood pressure and blood lipids influencing the prognosis of acute myocardial infarction were clarified. IRe- sults] The increasing of age, blood pressure, blood glucose and blood lipids and the history of stroke events could increase the mortality of patients with acute myocardial infarction, and the decreasing of cardiac enzymes and hemoglobin level also had the equal effect. [Conclusion]Regression analysis shows that blood pressure, age, triglyeeride, cholesterol and smok- ing are the vital independent predictors affecting the death of patients with acute myocardial infarction within a month, and age is the most important.
