目的 研究高血压病心肌缺血与冠状动脉主干直径指数变化 (LCDI)的关系。方法 2 2例高血压病心肌缺血性改变者 (A组 ) ,2 5例高血压病非缺血性改变者 (B组 )和 2 1例健康者 (C组 )加入本研究 ,比较各组的左室质量 ,左冠状动脉主干直径和直径指数及冠状动脉储备功能。结果 A组LCDI为(0 0 17± 0 0 0 4 )mm/g,显著小于B组的 (0 0 2 1± 0 0 0 5 )mm/g (P =0 0 11)和C组的 (0 0 2 3± 0 0 0 4 )mm/g (P =0 0 0 0 ) ,而后两组之间十分接近无差异。结论 高血压病心肌缺血性改变者左冠状动脉主干直径不能与左心室肥大成比例地扩大
Objective To study the relationship between myocardial ischemia and changes in the diameter of coronary artery (LCDI) in hypertensive patients. Methods Twenty-two hypertensive patients with myocardial ischemic changes (group A), 25 hypertensive non-ischemic subjects (group B) and 21 healthy subjects (group C) were enrolled in this study. Group left ventricular mass, left main coronary artery diameter and diameter index and coronary artery reserve function. Results The LCDI of group A was (0 0 17 ± 0 0 0 4) mm / g, which was significantly lower than that of group B (0 0 2 1 ± 0 0 05) mm / g (P 0 01) 0 0 2 3 ± 0 0 0 4) mm / g (P = 0 0 0 0). There was no significant difference between the last two groups. Conclusions The diameter of left main coronary artery can not be proportional to left ventricular hypertrophy in patients with hypertensive myocardial ischemia
