      Abstract:Aim To investigate the change of ambulatory blood pressure (BP) for 7 days after admission and its impact on the prognosis for patients with acute hemorrhage stroke. Methods 141 patients with new onset acute hemorrhage stroke were enrolled. The 7-day/24-hour (24 h) ambulatory BP was monitored and the odd points of time of BP were collected per two hours. Related clinical data of patients were collected. The prognosis of patients was determined according to the 30-day Glasgow outcome scale (GOS) after admission, and the relationships of prognosis and ambulatory BP changes such as admission systolic BP (SBP) and diastolic BP (DBP), 7-day daytime/nighttime mean SBP and DBP, 7-day BP circadian rhythm (BPCR) changes etc, were analyzed. Results 7-day/24-h mean BP decreased gradually among patients with new onset acute hemorrhage stroke. The BP on the seventh day was significantly lower than that on the first day (P<0.05). There was no significant difference in BPCR between two groups (P>0.05). There were significant difference between two groups in 7-day/24-h BP, admission Glasgow coma scale (GCS), white blood cells (WBC), hospital days, midline shift, broken into the ventricle, history of hypertension, and admission SBP(P<0.05). Multivariate logistic regression showed that admission high 24-h mean SBP, low admission GCS, high WBC, big amount of bleeding, basal ganglia hemorrhage were the risk factors for the poor prognosis of acute hemorrhage stroke (P<0.05). Conclusion 7-day/24-h BP was higher in the poor prognosis group among patients with new onset acute hemorrhage stroke, and admission severe disease, big basal ganglia hemorrhage, high admission 24-h SBP were indicators for the severity of condition and poor prognosis. Monitoring and control of admission 24-h SBP and the amount of bleeding are beneficial for improving the prognosis of acute hemorrhage stroke.

      Abstract:Aim To compare the difference in blood pressure control rate between ambulatory blood pressure(ABP) and office blood pressure (OBP) in chronic kidney disease (CKD) patients. Methods We enrolled 225 CKD patients complicated with hypertension in our hospital during 2012.5~2013.2. The general and blood pressure information about these patients were recorded. Results (1) Compared with CKD 1~2 patients, the decline of blood pressure control rate of office systolic blood pressure, 24 h average blood pressure, especially the night time blood pressure in CKD 5 patients were significantly different (P<0.05). (2)The blood pressure detection rate evaluated by OBP and ABP were different. In CKD 1~2 patients, ambulatory blood pressure detection rate were lower than office blood pressure control rate(79.6% vs 61.3%, P0.038), however, in CKD 5 patients, the result was on the contrary(83.5% vs 93.0%, P0.029). Conclusions (1) With the deterioration of renal function, the blood pressure control rate decreases. (2)There are differences between the blood pressure control rate evaluated by two blood pressure measurements in CKD patients of different clinical stage, so it is necessary for CKD patients to take ambulatory blood pressure measurements.

    • Association of Early Renal Impairment with Four Arterial Stiffness Index of Ambulatory Blood Pressure Monitoring in Essential Hypertensive Patients

      Abstract (1426)HTML (0)PDF 1.35 M (1410)Favorites

      Abstract:Aim To investigate the association of early renal impairment with four arterial stiffness indexes derived from ambulatory blood pressure monitoring (ABPM),and to provide comparison result between parameters in detecting the renal impairment of essential hypertension. Methods The 253 essential hypertensive patients were enrolled.The 24 hours mean pulse pressure (24h PP),pulse pressure index (PPI),ambulatory arterial stiffness index (AASI),symmetrical ambulatory arterial stiffness index (S-AASI),urine microalbumin to creatinine (mA1b/Cr) and estimated glomerular filtration rate (eGFR) were collected. Partial correlations and multiple stepwise regression analysis were performed to confirm the relationship between parameters of ABPM and renal lesion. The predictive power of four arterial stiffness parameters for early renal impairment was accessed by ROC curve. Results Correlation test showed a significant positively relationship of 24h PP,PPI,AASI,S-AASI with mA1b/Cr (r0.470,0.448,0.613 and 0.632 respectively,P<0.05),and eGFR were negatively correlated with them (r-0.308,-0.254,-0.399 and -0.352 respectively,P<0.05). Multiple linear regression analysis also showed independent correlation in 24h PP,PPI,AASI,S-AASI with eGFR. Area under ROC curve of S-AASI,AASI,24h PP and PPI were 0.692,0.686,0.681 and 0.655 respectively. The accuracy of the diagnosis was medium. The highest sensitivity was observed for S-AASI and PPI was with the highest specificity. Conclusion This study can support the idea that the four arterial stiffness parameters derived from ABPM had the similar ability to estimate hypertensive renal impairment.

      Abstract:Aim To discuss the relationship between ambulatory blood pressure monitoring(ABPM) parameters and carotid artery intima-media thickness(CA-IMT) in elderly hypertensive patients. Methods According to the results of carotid artery ultrasound examination the 205 patients divided into three groups:the patient were classified into the non-increased IMT group(control group)(IMT<1.0 mm),the increased IMT group(1.0 mm P><0.05).The incidence of coronary heart disease were 42.1% in the non-increased IMT group,53.1% in the increased IMT group,89.5% in the increased IMT with plaque group.The percent of dippers was 54.3%,62.9%,77.6% in each group.Which had significantly difference(P><0.05). The mean IMT had a positive correlation with 24hSBP,dSBP,nSBP,24hPP,dPP,nPP and the incidence of coronary heart disease(r=0.487,r=0.514,r=0.469,r=0.448,r=0.492,r=0.435,r=0.878,P><0.05).Which had significantly difference(P><0.05). Conclusion The rising of 24 hSBP,nSBP,24 hPP,nPP and patients who have lost the normal dipper rhythm of ambulatory blood pressure obviously will lead to the increase of IMT and the rising of plaque formation,which had a good correlation with the occurrence of coronary hart disease.

      Abstract:Aim To investigate the relationship between circadian rhythm of blood pressure and arterial stiffness. Methods We collected and analyzed ambulatory and clinical data in inpatients of a comprehensive department during 2004-2008 in the Affiliated Hospital of Dali University. Results In 242 inpatients,before and after adjustment of age,sex,antihypertensive treatment,24 h pulse rate and mean arterial blood pressure,compared with dippers(n=85),non-dippers(n=103),reverse dippers(n=42) and extreme dippers(n=12) had a significantly higher ambulatory arterial stiffness index and 24 h pulse pressure.There was no significant difference in age,plasma glucose,uric acid,total cholesterol and triglyceride among four groups(P>0.05). Conclusion Abnormal circadian rhythm of blood pressure was associated with arterial stiffness.
