摘要 目的:探讨急性ST段抬高型心肌梗死(STEMI)患者心肌缺血分级与心电图、超声心动图、CT参数及并发症发生的关系。方法:选取湖口县人民医院收治的STEMI患者89例为研究对象,根据Birnbaum等缺血分级标准,其中2级缺血52例,3级缺血37例,比较2级缺血和3级缺血患者心电图、超声心动图、CT参数及并发症发生情况的差异。结果:3级缺血患者入院时、溶栓后2h ST段抬高幅度分别为(0.81±0.26)mV和(0.48±0.19)mV,明显高于2级缺血患者,差异有统计学意义(P<0.05);3级缺血患者溶栓后2 h ST段回降≥50%比例为54.05%,明显低于2级缺血患者,差异有统计学意义(P<0.05);3级缺血患者梗死面积、CK-MB峰值分别为(19.05±3.72)%和(320.60±87.21)U/L,明显高于2级缺血患者,差异有统计学意义(P<0.05),而LVEF为(41.18±10.02)%,明显低于2级缺血患者,差异有统计学意义(P<0.05);3级缺血患者心律失常、心功能衰竭或休克发生比例分别为32.43%和29.73%,明显高于2级缺血患者,差异有统计学意义(P<0.05)。结论:相较于2级缺血,3级缺血的STEMI患者ST段回降率低,心肌梗死面积大,心律失常等并发症发生率高。
