摘要
目的探讨老年高血压病患者脉压、血压昼夜节律对颈动脉粥样硬化斑块的影响。方法将120例老年原发性高血压病患者按照脉压的不同,分为3组:PP1组(脉压<51mmHg),PP2组(脉压51～65mmHg),PP3组(脉压>65mmHg);按照24h动态血压检测结果分为两组:夜间血压下降率<10%即昼夜节律消失,为非杓形组,共60例;夜间血压下降率≥10%即昼夜节律存在,为杓形组,测量颈动脉粥样硬化斑块程度。结果随着脉压增高,颈动脉粥样硬化斑块程度越严重,PP3>PP2>PP1(P<0.05);非杓形组夜间收缩压及舒张压明显高于杓形组,非杓形组的颈动脉粥样硬化斑块程度分级明显高于杓形组(P<0.05)。结论脉压增大及昼夜节律异常是颈动脉粥样硬化斑块形成的危险因素。
Objective To investigate the relationship between ambulatory pulse pressure,day-night rhythm and carotid atherosclerosis in elderly people with essential hypertension.Methods 120 elderly essential hypertensive patients were divided into 3 groups according to the grade of pulse pressure,PP1 group(pulse pressure<51mmHg),PP2 group(51mmHg≤pulse pressure≤65mmHg),PP3 group(pulse pressure>65mmHg).They were divided into 2 groups according to the blood pressure-decreasing ratio,non-dipping group(ND group, bloo...
