①目的探讨急性心肌梗塞（ＡＭＩ）病人的临床概况和发病趋势。②方法对本院１９７９年１月～１９９５年１２月住院ＡＭＩ病人７９８例进行不同阶段的对比分析。③结果老年人ＡＭＩ的发病有明显增加趋势（χ２＝５．０１，Ｐ＜０．０５），ＡＭＩ占心血管病的住院百分比逐年增加；心原性休克、心脏骤停和心力衰竭并发症的发生率明显降低（χ２＝５．０３，Ｐ＜０．０５）。病死率明显下降（９．７％），病死主要发生在发病７ｄ之内，病死原因以心力衰竭、心原性休克和心脏骤停为主；高血压、高胆固醇是发病的主要危险因素；再梗塞发生率明显增加（χ２＝４．８７，Ｐ＜０．０５）。④结论降低高胆固醇和高血压、减少并发症、预防再梗塞和降低病死率是防治ＡＭＩ面临的主要问题。
①Objective To investigate the clinical situation and trend of patients with acute myocardial infarction (AMI). ② Methods The hospital from January 1979 to December 1995 hospitalized 798 cases of AMI patients at different stages of comparative analysis. Results The incidence of AMI in elderly was significantly increased (χ2 = 5.01, P <0.05), and the percentage of hospitalizations with AMI in cardiovascular disease increased year by year. The incidence of AMI, cardiac arrest and heart failure The incidence was significantly lower (χ2 = 5.03, P <0.05). The mortality was significantly decreased (9.7%). The main cause of death was within 7 days of onset. The causes of death were heart failure, cardiogenic shock and cardiac arrest. Hypertension and high cholesterol were the main risk factors. The incidence of infarction increased significantly (χ2 = 4.87, P <0.05). Conclusion Conclusion Reducing high cholesterol and high blood pressure, reducing complications, preventing re-infarction and reducing mortality are the main problems in the prevention and treatment of AMI.
