目的:探讨急性下壁心肌梗死患者心电图ST段抬高形态对预后的判断价值。方法:选取2013-10-2015-10我院接诊的200例急性下壁心肌梗死患者,依据心电图ST段抬高形态结果将其分为新月型(n=63)、斜线型(n=85)和弓背型(n=52),观察对比3组患者心肌肌钙蛋白I(cTnI)峰值、左室射血分数(LVEF)水平、病情和临床指标及病变血管数量的差异。结果:弓背型患者cTnI峰值显著高于斜线型和新月型(P<0.05),LVEF水平低于斜线型和新月型,但差异无统计学意义;弓背型患者梗死前心绞痛发生率显著低于斜线型和新月型患者,弓背型合并右室梗死、异常Q波的发生率均显著高于斜线型和新月型患者,且3组间比较差异有统计学意义(P<0.05,P<0.01)。结论:在急性下壁心肌梗死患者中,ST段抬高形态为弓背型的患者预后较差,斜线型预后次之,新月型预后较好,可根据患者的病情状态对患者进行对症治疗。
Objective: To investigate the prognostic value of ST segment elevation in ECG in patients with acute inferior myocardial infarction. Methods: A total of 200 patients with acute inferior myocardial infarction admitted to our hospital from October 2013 to October 2015 were enrolled in this study. They were classified into crescent type (n = 63), oblique type (n (N = 52). The differences of cTnI, LVEF, disease and clinical parameters and the number of vascular lesions were observed and compared between the three groups. Results: The peak of cTnI in patients with dorsal bowel was significantly higher than that of diagonal and crescent (P <0.05), LVEF was lower than that of oblique and crescent, but the difference was not statistically significant. The incidence was significantly lower than the slanted and crescent type patients, arcuate dorsal combined right ventricular infarction, the incidence of abnormal Q waves were significantly higher than the slashes and crescent patients, and the difference between the three groups were statistically significant Significance (P <0.05, P <0.01). CONCLUSIONS: In patients with acute inferior myocardial infarction, the prognosis of patients with ST elevation segment dorsal bowel type is poor, followed by oblique type prognosis, and the prognosis of crescent type is good. Patients with symptomatic disease can be treated according to the patient’s condition treatment.
