Some patients with unstable angina develop a deep T-wave inversion in ECG leads V1 to V4. It has been suggested that this special ECG pattern is associated with a severe stenosis of the left anterior descending (LAD) coronary artery. We have studied 73 of this patients. All of them had an LAD involvement, nearly always as severe atherosclerotic plaque and in 5% of the cases due to non-atherosclerotic alterations (milking or spasm). Angioplasty was performed in 33% and bypass surgery in 61%. In both cases the immediate results were good (0% and 4% respectively in-hospital mortality) as well as the outcome (12% restenosis and 0% late mortality respectively). The ECG signs disappeared in the year after.
一些不稳定型心绞痛患者在心电图V1至V4导联出现深T波倒置。有人认为这种特殊的心电图模式与左前降支（LAD）冠状动脉严重狭窄有关。我们研究了73例此类患者。他们均有LAD受累，几乎总是存在严重的动脉粥样硬化斑块，5%的病例是由于非动脉粥样硬化性改变（挤压或痉挛）。33%的患者接受了血管成形术，61%的患者接受了搭桥手术。在这两种情况下，即刻结果良好（住院死亡率分别为0%和4%），预后也良好（再狭窄率分别为12%，晚期死亡率为0%）。心电图征象在术后一年内消失。
