    【摘要】  目的  探讨原发性高血压患者冠状动脉病变狭窄程度与脉压指数的相关性。方法  对拟诊冠心病（CHD）的164例高血压病患者以标准Judkins法行冠状动脉造影术,计算机定量分析系统（QCA）分析冠状动脉狭窄程度并计算其冠状动脉病变积分（CSS）。标准台式水银血压计测定外周肱动脉收缩压（SBP）和舒张压（DBP）并计算脉压指数（PPI）。结果  原发性高血压患者CHD的发生与其PPI及PP的相关性显著。结论  PPI及PP是高血压病患者CHD发展的一个重要的、独立的预测指标。

     Correlation between coronary artery disease and pulse pressure in patients with essential hypertension

    【Abstract】  Objective  To evaluate the relationship between coronary artery disease and and pulse pressure index in patients with essential hypertension.Methods  Coronary angiography was performed in 164 cases who were suspected to have coronary heart disease （CHD）.Then the severity of coronary artery lesions was  analysed by quantitive computer system（QCA） to acquire coronary artery score（CSS）.Brachial systolic blood pressure（SBP）,diastolic blood pressure（DBP） and pulse pressure index（PPI） were measured by sphygmomanometer.Results  The development of CHD  in patients with essential hypertension has significantly correlation with  PPI and  PP.Conclusion  PPI and  PP are independent and important predictors for developing CHD in……
