踝臂指数与冠状动脉病变程度的研究-内科学(心内科)专业论文.docxVIP

温州医学院硕：t学位论文计算采用hHh推荐的方法，单侧hBI的计算为该侧踝动脉收缩压与双侧肱动脉收 温州医学院硕：t学位论文 计算采用hHh推荐的方法，单侧hBI的计算为该侧踝动脉收缩压与双侧肱动脉收 缩压的最高值之比，最后取左右两侧ABI的低值作为该患者的ABI。 结果 冠脉造影正常组(n=47)和冠心病组(n=104)hBI比较差异有显著性 (PO．05)。正常组(n=47)、单支病变组(n=35)、二支病变组(n=38)、三支病变组 (n=31)ABI两两比较，仅正常组与三支病变组比较差异有显著性(PO．05)。正常 组(n=47)、轻度病变组(n=73)、严重病变组(n=31)ABI两两比较，仅正常组与严重 病变组比较差异有显著性(PO．05)．非严重病变组(n=120)和严重病变组 (n=31)ABI比较差异有显著性(PO．05)。但正常组(n=47)、单支病变组(n=35)、二 支病变组(n-38)、轻度病变组(n=73)之间ABI两两比较均无显著性差异(PO．05)。 本研究对患者的病变冠状动脉积分、冠状动脉病变积分与hBI进行线性相关分析 示：病变冠状动脉积分、冠状动脉病变积分均与ABI里显著负相关(P0．05)。 结论在我国，ABI降低对冠状动脉严重病变有预测价值。病变冠状动脉积分、冠 状动脉病变积分越高，冠状动脉病变程度越严重，ABI的数值越小．hBI不仅有助 于诊断冠心病，而且能反映冠状动脉病变程度，hBI可用作动脉粥样硬化的非侵袭 性筛选指标，是预测冠状动脉硬化程度的一种简单可靠的指标。 [关键词] 踝臂指数；冠心病；冠状动脉造影 温州医学院硕上学位论文Relationship 温州医学院硕上学位论文 Relationship between Ankle-brachial index and Severity of Coronary artery disease Abstract objective Ankle-brachial index(ABI)is the best hurtless marker to diagnosis peripheral arterial disease(PAD)．Atherosclerosis is a system disease．Coronary heart disease and PAD am the important appearance of atherosclerosis．According to the results ofcoronary angiography,we study the relationship bct3A,∞n ankle-brachial index (ABD and severity ofcoronary artery disease in Chinese． Methods 151 cases were selected from January of 2006 to December of 2006，who had done coronary angiography because of diagnosis or Iieatmant．The excluding standards are listed勰followinff．had the history ofperoutaneous transhmfinal coronary angioplasty(PTCA)，coronary artery bypass graR or thrombolysis therapy；,cannot measure the ABI because of the amputated extremity or trauma of lower limber． Among these 151 cases，male are 101 17．,ases(66．9％)，female a他50 cases(33．1％)，and the mean age is 64．the 151 cases are divided into different groups according to the results of coronary artcriongruphy,and compare the ABI of different groups．We adopt the lesion coronary artery integral and coronary artery lesion integral to evaluate the lesion degree of coronary artery．Different numbers are given accordin
