目的观察老年男性高血压收缩压及舒张压对颈动脉斑块的影响。方法对220例老年男性高血压病患者根据收缩压及舒张压水平分为舒张压≤90mm Hg而收缩压≥140、舒张压≥90mm Hg而收缩压≤140mm Hg和收缩压≥140mm Hg且舒张压≥90mm Hg三组,对入选患者测量颈动脉内膜—中膜厚度(IMT)。结果随着收缩压增大,颈总动脉IMT及斑块检出率明显增高(P均<0.01)。结论收缩压增高是颈动脉粥样硬化斑块形成的危险因素。
Objective To observe the effect of systolic blood pressure and diastolic blood pressure on carotid artery plaque in elderly men. Methods 220 elderly hypertensive patients were divided according to systolic and diastolic blood pressure diastolic blood pressure ≤ 90mm Hg systolic blood pressure ≥ 140, diastolic blood pressure ≥ 90mm Hg systolic blood pressure ≤ 140mm Hg and systolic blood pressure ≥ 140mm Hg and diastolic blood pressure ≥90 mm Hg three groups, carotid intima-media thickness (IMT) was measured in the selected patients. Results With the increase of systolic blood pressure, carotid artery IMT and plaque detection rate was significantly increased (P all <0.01). Conclusion Increased systolic blood pressure is a risk factor for the formation of carotid atherosclerotic plaque.
