老年冠心病合并高血压患者的颈动脉硬度与冠脉造影的相关性研究

摘要

目的 探讨合并高血压痛的老年冠心痛患者颈动脉硬度与冠状动脉粥样硬化的关系.方法 通过对40例合并高血压病的老年冠心病患者行冠状动脉造影,明确冠状动脉病变并评分;同时行颈动脉超声检查,检测颈动脉硬度.结果 合并高血压病的老年冠心病患者的颈动脉紧张度、扩张性较老年冠心病组及健康老年组低,而僵硬度则增高,差异有统计学意义(P<0.01);不同支数冠状动脉病变之间比较颈动脉硬度差异有统计学意义(P<0.01);冠状动脉病变积分与颈动脉紧张度、扩张性呈负相关(r=-0.353,-0.125,P<0.01),而与僵硬度呈正相关(r=0.376,P<0.01).结论 合并高血压病的老年冠心病患者的颈动脉硬度与冠状动脉病变程度明显相关,可通过了解颈动脉病变间接了解冠状动脉病变.%Objective To observe the relationship between carotid stiffness and coronary angiography in elderly patients of coronary heart disease (CHD) complicated with hypertension.Methods The patients were divided into three groups.Coronary angiography was performed in 40 elderly patients of CHD complicated with hypertension.The carotid stiffness was measured by ultrasound.Results There were significant differences on hypertension in arterial stain,arterial distensibility and arterial stiffness.There was significant correlation between coronary angiography score and carotid stiffness among three groups(r=-0.353,-0.125,0.376,P<0.01).Conclusion There is close relationship between carotid atherosclerosis and coronary atherosclerosis in elderly patients of CHD complicated with hypertension.
