中心动脉压对冠心病患者冠脉病变的评估价值

Evaluation of Central Aortic Pressure on Coronary Artery Lesions in Patients with Coronary Artery Disease

【目的】探讨冠心病患者的中心动脉血压（CAP）变化情况及其对冠脉病变的评估价值。【方法】选择本院收治的145例行冠状动脉造影的冠心病患者，根据其冠脉造影结果将其分为单支病变组（7／=42）、双支病变组（n=65）、三支病变组（n=38），比较三组患者外周动脉血压（PAP）与CAP的差异。【结果】单支病变组、双支病变组、三支病变组外周动脉的收缩压（SBP）、舒张压（DBP）、脉压（PP）以及中心动脉的SBP、DBP比较差异均无统计学意义（均P〉0．05）。双支病变组及三支病变组中心动脉的PP均高于单支病变组，三支病变组高于双支病变组，差异均具有统计学意义（均P〈0．01）。【结论】中心动脉的PP能够反映冠心痛患者冠脉病变程度，冠心病合并高血压患者在降压的过程中，应关注中心动脉的PP变化。

[Objective]To evaluate the effect of central aortic pressure changes （CAP） on coronary artery lesions in patients with coronary artery disease.[Methods]145 patients with coronary heart disease who werte treated by routine coronary angiography were selected in our hospital and were divided according to the＇coronary angiography results into single-lesion group （ n =42）, the double-lesion group （ n = 65） and the triplelesion group （ n =38）, the difference of peripheral arterial blood pressure （PAP） and the CAP of the three groups of patients were compared.[Results]The systolic blood pressure （8BP） of peripheral artery; diastolic blood pressure （DBP）, pulse pressure （PP） as well as the central artery SBP and DBP of the three groups had no statistical significance （P 〉0.05）. PP of central artery of the Double group and the Triple group were higher than that of the Single group, and the Triple group is higher than the double group, the differences were statistically significant （ P 〈0.01）.[Conclusion]The central artery PP may reflect the degree of coronary artery lesions in patients with coronary heart disease. In the process of decompression, high blood pressure pa- tients with coronary heart disease should be focused on the changes of pulse pressure （PP） of central artery.
