目的：探讨年龄对急性心肌梗死（acute myocardial infarction ，AMI）患者近期预后的影响。方法：收集2003 年至2012 年于哈尔滨医科大学附属第一临床医院CCU 住院的AMI 患者共3434 例，依年龄分为四组：青年组（≤ 44 岁）338 例、中年组（45-59 岁）1194 例、老年组（60-79 岁）1740 例、高龄组（≥ 80 岁）162 例，住院期间发生的不良心血管事件包括：充血性心力衰竭538 例，恶性心律失常134 例，心源性休克134 例，心脏破裂24 例，死亡58 例，联合事件（包括两种或两种以上述不良心血管事件）162 例，分析不同年龄组患者住院期间不良心血管事件的发生情况。结果：充血性心力衰竭、心源性休克、死亡、心脏破裂和联合事件的发生率在四个不同年龄组之间均具有统计学意义（P＜0.01）。除高龄组外，其他各年龄组不良心血管事件的发生率有随年龄增加而升高的趋势。结论：年龄是AMI患者近期预后的影响因素。＜80 岁的AMI患者住院期间不良心血管事件的发生率有随着年龄的增加而升高的趋势，≥ 80 岁的AMI患者尚有待于进一步研究。

英文摘要:

Objective:To investigate the impact of age on short-term prognosis in the hospitalized patients with acute myocardial infarction (AMI).Methods:The data of 3431 patients hospitalized in department of CCU of the First Affiliated Hospital of Harbin Medical University from 2003 to 2012 was collected. All patients were divided into four groups by age: youth group (age≤ 44), middle-age group (age 45 to 59), elderly group (age 60 to 79) and advanced age group (age≥ 80). Adverse cardiovascular events of all patients during hospitalization was detected including congestive heart failure of 538 cases, malignant arrhythmias of 134 cases, cardiogenic shock of 134 cases , cardiac rupture of 24 cases, death of 58 cases, joint events of 162 cases (including two or more adverse cardiovascular events). The occurrence of adverse cardiovascular events during hospitalization of patients in different age groups was analyzed.Results:The incidence of congestive heart failure, cardiac shock, death, cardiac rupture and allied events in the different four groups has a significant difference (P＜0.05). In addition to the advanced age group, the incidence of adverse cardiovascular events in the other age groups was increased with age.Conclusion:Age is one factor affecting the short-termprognosis of patients with AMI. The incidence of adverse cardiovascular events in the patients under 80 years old with AMI during hospitalization have a tendency to increase with age, while the further study is still needed for the patients more than 80 years old.
