摘　　要：目的探讨急性ST段抬高型心肌梗死(STEMI)患者ST段回峰幅度联合外周血白细胞计数与预后的关系.方法选取STEMI患者100例,收集其入院时第一份心电图、外周血白细胞计数及经皮冠状动脉介入(PCI)术后心电图.根据术后心电图ST段回峰幅度将患者分为ST段回峰幅度≥50%组、ST段回峰幅度<50%组;根据外周血白细胞计数将患者分为外周血白细胞计数<10×10^(9)/L组、外周血白细胞计数≥10×10^(9)/L组.通过分析心功能及MACE事件比较患者预后情况.结果ST段回落幅度≥50%组及ST段回峰幅度<50%组在性别、是否高血压、糖尿病等方面比较差异无统计学意义(P>0.05),但ST段回落幅度≥50%组的吸烟率(76%)明显高于ST段回峰幅度<50%组(24%)(P<0.05);ST段回落幅度≥50%组在术后1月、半年、1 a心功能改善明显(P<0.05),ST段回峰幅度<50%组心功能改善不明显(P>0.05).外周血白细胞计数<10×10^(9)/L组、≥10×10^(9)/L组在性别、是否高血压、糖尿病等方面比较差异无统计学意义(P>0.05);外周血白细胞计数<10×10^(9)/L组在术后1月、半年、1 a心功能改善明显(P<0.05),而外周血白细胞计数≥10×10^(9)/L组心功能改善不明显(P>0.05).结论分析STEMI患者PCI术后ST段回峰幅度与外周血白细胞计数情况有助于判断患者预后.Objective To investigate the relationship between the prognosis of acute ST segment elevation myocardial infarction(STEMI)patients with ST segment peak amplitude and peripheral blood leukocyte count.Method 100 patients with STEMI were selected and their first ECG,peripheral blood leukocyte count and ECG after PCI were collected.According to the amplitude of ST segment return peak of ECG after operation,the patients were divided into groups with ST segment return peak amplitude≥50%and ST segment return peak amplitude<50%;According to the peripheral blood leukocyte count,they were divided into<10×10^(9)/L group and≥10×10^(9)/L group.The prognosis of patients was compared by analyzing cardiac function and MACE events.Results There was no significant difference in sex,hypertension,diabetes or not between groups with≥50%ST segment recession and those with<50%ST segment recession(P>0.05).The smoking rate(76%)in groups with≥50%ST segment recession was significantly higher than that in group with<50%ST segment recession(24%)(P<0.05).There was no significant difference between<10×10^(9)/L group and≥10×10^(9)/L group in terms of sex,hypertension,diabetes or not(P>0.05);Cardiac function improved significantly 1 month,half a year and 1 year after operation(P<0.05),but not significantly in the group with ST segment return peak amplitude<50%.The cardiac function of<10×10^(9)/L group was significantly improved(P<0.05),while that of≥10×10^(9)/L group was not significantly improved.Conclusion The analysis of ST segment peak amplitude and peripheral blood leukocyte count in patients with STEMI after PCI is helpful to judge the prognosis of patients.
