摘　　要：目的探讨下壁急性心肌梗死aVR导联ST段压低的意义。方法将81例有Q波急性下壁心肌梗死病人根据aVR导联ST段有无压低（以压低≥0.01 mV为准）分为ST段压低组（A组）35例和ST段无压低组（B组）46例。两组均行冠状动脉造影,比较两组病例的心功能不全,恶性室性心律失常,住院病死率,梗死相关血管狭窄程度及病变血管支数。结果两组比较,A组有较高的心功能不全,恶性室性心律失常发生率及较高的住院病死率,两组比较差异有统计学意义（P〈0.01）。A组多支血管病变例数较多,梗塞相关血管狭窄程度较重,两组比较差异有统计学意义（P〈0.05）。结论aVR导联ST段压低的急性下壁心肌梗死患者较无aVR导联ST段压低的急性下壁心肌梗死患者近期预后较差。与梗死相关血管狭窄程度严重,梗死面积较大及病变血管支数较多有关。Objective To study the clinical significance of anterior ST - segment depression in leads AVR in patients with inferior myocardial infarction. Methods Eight - one patients with first acute inferior myocardial infarction were divided into group A （Maximal precordial ST- segment depression in leads AVR n = 35 ）and group B（ No precordial ST -segment depression n = 46）. The two groups were underwent coromary angiography. The heart failure, serious arrhythmias, in - hospital mortality, the degree of coronary artery stenosis and vessel coronary diease in the two groups were compared. Results Compared with group B, group A had high heart failure ,serious arrhythmias, in- hospital mortality（ P 〈 0.01 ）And had high multi -vessel disease, and much severe degree of coronary artery stenosis degree of coronary artery stenosis （ P 〈 0.05 ）. Conclusion THE short - term prognosis of anterior ST - segment depression in leads AVR with acute inferior myocardial infarction was less than that of No anterior ST - segment depression in leads AVR group. It possibly is related to the more severe degree of coronary artery stenosis, multi - vessel disease and the larger infarction area of acute myocardial infarction.
