ABSTRACT
Objective To evaluated the relationship of ambulatory pulse pressure and severity intracranial arterial stenosis. Methods 165 ischemic stroke patients with intracranial arterial stenosis were selected as stenosis group. And 142 patients with no obvious intracranial arterial stenosis were selected as control group. All patients were given ambulatory blood pressure monitoring. 24 h average systolic pressure ,diastolic pressure and ambulatory pulse pressure were measured. Results Ambulatory pulse pressure of stenosis group[(73.02 ± 10.86)mmHg]was significantly higher than that of control group[(59.63±12.96)mmHg,P<0.01]. Ambulatory pulse pressure of mod-erated stenosis group[(69.73±9.3)mmHg,P < 0.05]was significantly higher than that of control group[(59.63± 12.96)mmHg,P<0.01]. Ambulatory pulse pressure of severe stenosis group[(77.36±7.94)mmHg]was signifi-cantly higher than that of moderate stenosis group[(69.73±9.3)mmHg,P < 0.05]. The level of ambulatory pulse pressure was independent risk factors of intracranial arterial stenosis(OR value:1.092). Conclusions Ambulatory pulse pressure is significantly related to the severity of intracranial arterial stenosis and is an independent risk factor for intracranial arterial stenosis.

ABSTRACT
Objective To assess the relationship between ambulatory pulse pressure (PP),pulse pressure indices (PPI) and the severity of cognitive function.Methods Sixty patients with severe,moderate,mild vascular cognitive impairment(VCI) as the research object,and forty healthy people as control group.All of the patients of ambulatory blood pressure were monitored.Results Severe VCI group of PP and PPI was significantly higher than moderate,mild VCI group and the control group (PP (mmHg):(59.10 ± 11.82,54.94 ± 10.86,50.28 ±8.33,45.54±9.22,P＜0.05),PPI:(0.61±0.08,0.53±0.06,0.44±0.05,0.37±0.03,P＜0.05),and the MMSE score was significantly lower than moderate,mild,and the control group(15.56±2.64,19.32±3.32,22.62±3.11,26.45±2.94,P＜0.05).Moderate VCI group of PP and PPI was significantly higher than the control group(P＜0.05).MMSE score was significantly lower than mild VCI and the control group(P＜0.05).Linear correlation analysis showed that PP and PPI was significantly negative related to MMSE score.Conclusion The increase of dynamic pulse pressure,pulse pressure index is associated with the damage of cognitive function.

ABSTRACT
60 mm Hg (PP1 group) or 40 mm Hg≤PP≤60 mm Hg (PP2 group),1 mm Hg =0.133 kPa.Ambulatory blood pressure monitoring,the serum and urine ?_2-MG,urine mAlb,blood BUN and Cr were measured in both groups,the blood pressure,serum and urine ?_2-MG,urine mAlb,blood BUN and Cr were compared between two groups. Results Compared with PP2 group,the PP1 group showed higher levels of renal function indexes. Conclusion Renal damage is related with pulse pressure in senile essential hypertension.
ABSTRACT
Objective To find out the relationship between ambulatory pulse pressure (24 h PP) and left ventricular hypertrophy (LVH) and the enlarged diameter of aortic root (AOD) in aged pati ents with essential hypertension.Methods 118 aged patients with essential hypertension we r e examined by ambulatory blood pressure (ABP) and echocardiography,the different index of ABP and left ventricular mass index (LVMI) and AOD were measured.The p atients were divided into group A (24 h PP≥60 mmHg) and group B (24 h PP
ABSTRACT
Objective To explore the possibility of dynamic pulse pressure (DPP) being used to predict cardiovascular events in old men with normotension. Methods During May 1995 to September 2001, a 24h DPP monitoring was carried out on 858 old men with normotension (60-91 years old, BP60 mmHg, respectively. The first attack of cardiovascular event was recorded. Results In the 3 groups of subjects, the incidence of total cardiovascular events (100 persons per year) was 3.7, 5.8, and 9.1 respectively (log-rank test, P=0.000 9, 0.000 2, 0.000 0). After adjustment for the other risk factors including age, hypertension history, diabetes and previous cardiovascular disease, it has been found that the data of dynamic pulse pressure is of a significant value for predict cardiovascular events (P
