Effects of the difference between peripheral arterial and central arterial blood pressures on patients with cerebral lacunar infarction

Abstract

Objective To analyze the effects of the difference between the peripheral arterial and the central arterial blood pressures on cerebral lacunar infarction.Methods The cerebral lacunar infarction group (n =129) and control group (n =122) were set up.The systolic blood pressure (SBP) and diastolic blood pressure (DBP) of the ascending aorta and radial artery were simultaneously recorded postoperatively,and mean artery pressure (MAP) and pulse pressure (PP) were calculated.Results There was no significant difference between cerebral lacunar infarction group and control group in basic blood pressure,blood lipid,blood glucose,heart rate,age and sex (all P ＞ 0.05).The difference of SBP [(7.6 ± 2.3) mmHg(1 mmHg=0.133 kPa) vs.(23.6 ±5.7) mmHg],MAP [(6.6 ±2.1) mmHg vs.(20.1 ±6.2) mmHg] and PP [(5.8 ± 1.7) mmHg vs.(12.9 ±5.3) mmHg] between the peripheral and aortic pressures in cerebral lacunar infarction group was higher than in control group (P ＜ 0.05),but there was no significant difference in SBP [(132.8 ± 13.1) mmHg vs.(134.9 ± 12.5) mmHg],MAP [(107.8 ± 10.1) mmHg vs.(111.2 ±9.4) mmHg],PP [(51.7 ±6.9) mmHg vs.(49.7 ±6.2) mmHg],and DBP [(84.2 ± 9.3) mmHg vs.(82.1 ± 8.6) mmHg] in radial artery between the two groups (all P ＞0.05),and there was no significant difference in DBP [(80.7 ±7.5) mmHg vs.(76.7 ±7.2) mmHg] in the ascending aorta and the difference of DBP between the peripheral and aortic pressures between the two groups,too (all P ＞ 0.05).Conclusion The difference of SBP,MAP and PP between the peripheral arterial and the central arterial blood pressures was correlated with cerebral lacunar infarction.
