本文对78例首次急性心肌梗塞患者的研究指出,前壁心肌梗塞患者入院后8小时内高峰ST段抬高总和(∑ST)无变化或下降<35％时,∑ST与出院时∑Q和ORS积分明显相关(r=0.68和r=0.85)。但前壁心肌梗塞伴最初8小时内∑ST下降≥35％或下壁心肌梗塞时,∑ST与出院时心肌梗塞大小无明显关系。因此,在前壁心肌梗塞伴最初8小时内无明显ST段降低时,∑ST对预测出院时心肌梗塞大小具有重要价值。
This study of 78 patients with first-ever acute myocardial infarction found that patients with anterior myocardial infarction within 8 hours after admission peak ST-segment elevation (ΣST) did not change or decrease <35%, ΣST and discharge ΣQ and ORS scores were significantly correlated (r = 0.68 and r = 0.85). However, there was no significant relationship between ΣST and the size of myocardial infarction at discharge in the anterior wall myocardial infarction with ΣST decrease ≥35% or inferior wall myocardial infarction in the first 8 hours. Therefore, ΣST is of great value in predicting the size of myocardial infarction at discharge in the absence of significant ST-segment elevation in the anterior myocardial infarction with initial 8 hours.
