摘　　要：目的探讨冠心病患者Macruz指数变化与左室舒张功能的关系。方法应用常规12导联心电图技术,测定90例冠心病患者P/P-R段比值(即Macruz指数值),同时应用多普勒超声心动图测定二尖瓣血流频谱E/A比值,并与85例非冠心病患者作比较。结果1支和3支病变E/A比值均<1,2支病变E/A 比值>1。3组冠心病患者P/P-R 段比值均>1.6。结论Macruz指数有助于评价冠心病患者的左室舒张功能,某种程度上比E/A比值更优越。Objective To study the association of Macruz index with left ventricular diastolic function of patients with coronary artery disease (CAD). Methods The ratio of P/P-R segment (Macruz index) was measured using regular 12-lead electrocardio- graphy in 90 CAD patients, whose mitral E/A wave ratios were determined by means of Doppler echocardiography. The measurements were also performed in 85 patients with non-coronary artery diseases for comparison. Results The mitral E/A ratio of the CAD patients with 1 or 3 branches involved was lower than 1, while in patients with two branches involved, the E/A ratio exceeded 1. The P/P-R segment ratio of the 3 CAD groups was all over 1.6. Conclusion The Macruz index is more helpful than E/A ratio to some extent in estimating the left ventricular diastolic function of CAD patients.
