急性心肌梗死面积、QRS积分与临床预后的关系

Relationship between size of myocardial infarction and QRS scores and clinical prognosis in patients with acute myocardial infarction

为探讨急性心肌梗死面积、QRS积分与临床预后的关系 ,采用Michelle等公式及WagnerQRS评分标准 ,观察113例急性心肌梗死患者。结果显示急性前壁心肌梗死死亡组心肌梗死面积 (22.14±6.26)、QRS积分(7.28±3.74)均较存活组显著增大 (17.83±5.65、4.91±2.63,P<0.05) ,存活组QRS积分与梗死面积的回归方程为 :QRS积分=2.59+0.13×梗死面积 ,但急性下壁心肌梗死死亡组与存活组这两项指标差异无显著意义 (P>0.05)。提示利用入院时12导联心电图测算心肌梗死面积 ,对判断急性前壁心肌梗死临床预后有重要意义 ,但对急性下壁心肌梗死无意义。

To assess relationship between size of myocardial infarction and QRS scores and clinical prognosis in patients with acute myocardial infarction,size of myocardial infarction,QRS scores were studied with Michelle′s equation and Wagner′s standard respectively,clinical prognosis analysed and regression correlation studied in 113 consecutive patients with acute myocardial infarction.Results showed both QRS scores and size of myocardial infarction were significantly higher in death group than those in survival group in patients with acute anterior myocardial infarction.Two indexes,however,showed no significance between death group and survival group in patients with acute inferior myocardial infarction.Conclusion:Size of myocardial infarction measured with admission 12 _ lead electrocardiogram might be used to evaluate clinical prognosis in patients with acute anterior myocardial infarction,but not applicable to patients with acute inferior one.
