ABSTRACT

Objective To investigate the correlation between 24-h ambulatory blood pressure variability and the overall burden of cerebral small vessel disease (CSVD) in patients with acute ischemic stroke. Methods From March 2016 to December 2017, consecutive patients with acute ischemic stroke admitted to the Department of Neurology, the Affiliated Changshu Hospital of Soochow University were enrolled. The 3. 0 T-MRI was used to assess asymptomatic lacunar infarction, white matter hyperintensities, cerebral microbleeds, and enlarged perivascular spaces within 24 h after admission, and the total CSVD score (0-4) was calculated. 24-h ambulatory blood pressure monitoring was performed 24 to 72 h after admission. Ordinal logistic regression analysis was used to determine the independent correlation between the 24-h ambulatory blood pressure-related index and the total CSVD score. Results A total of 220 patients with acute ischemic stroke were enrolled. The patients were divided into five groups according to the total CSVD score. Univariate analysis showed that there were significant differences in age, homocysteine, the proportion of hypertension, as well as 24 h, daytime and nighttime mean systolic blood pressure (SBP), and coefficient of variation of daytime SBP among the 5 groups (all P < 0. 05). Ordinal logistic regression analysis showed that age (odds ratio [OR] 1. 078, 95% confidence interval [CI] 1. 051-1. 106; P < 0. 001), 24-h mean SBP (OR 1. 043, 95% CI 1. 026-1. 060; P < 0. 001), daytime mean SBP (OR 1. 042, 95% CI 1. 025-1. 059; P < 0. 001), nighttime mean SBP (OR 1. 034, 95% CI 1. 019-1. 049; P < 0. 001), and coefficient of variation of daytime SBP (OR 1. 129, 95% CI 1. 052-1. 210; P = 0. 003) were independently correlated with the total CSVD score. Conclusions The elevated 24 h, daytime and nighttime mean SBP levels and coefficient of variation of daytime SBP are independently correlated with the severity of overall CSVD burden in patients with acute ischemic stroke.

ABSTRACT

Objective To investigate the correlation between 24-h ambulatory blood pressure (BP) variability and cerebral microbleeds (CMBs) in patients with acute ischemic stroke. Methods Consecutive inpatients with acute ischemic stroke were prospectively enrolled. 24-h ambulatory BP was monitored. Magnetic susceptibility-weighted imaging was used to evaluate CMBs and their locations. Univariate analysis was used to compare the baseline data between the CMBs group and the non-CMBs group. Multivariate logistic regression analysis was used to determine the independent correlation between ambulatory BP related indexes and CMBs. Results A total of 178 patients with acute ischemic stroke were enrolled, including 114 males, aged 67.6 ±10.8 years, and 90 (50.6%) with CMBs. The proportion of hypertension and asymptomatic lacunar infarction, periventricular and deep white matter high signal score, 24-h, daytime, nighttime mean systolic and diastolic BP, 24-h, and daytime systolic BP variability in the CMBs group were significantly higher than those in the non-CMB group (all P<0.05). Multivariate logistic regression analysis showed that 24-h systolic BP variability (odds ratio 1.133, 95% confidence interval 1.023-1.255; P=0.016) and daytime mean systolic BP (odds ratio 1.045, 95% confidence interval 1.022-1.069; P<0.001) had significant independent correlation with CMBs. Conclusion 24-h systolic BP variability and daytime mean systolic BP were the independent risk factors for CMBs in patients with acute ischemic stroke.

ABSTRACT

Objective To evaluate the feasibility, safety and effectiveness of interventional occlusion with thin waist occluder for perimembranous ventricular septal defect with pseudoaneurysm. Methods During the period from March 2008 to March 2013 at Shanghai Yodak Cardiothoracic Hospital , interventional occlusion with thin waist occluder was carried out in a total of 96 patients with perimembranous ventricular septal defect (VSD) complicated by pseudoaneurysm. The patient’s age varied from 2 years to 36 years. Before the procedure, routine left ventricular angiography and ascending aortic angiography were carried out. Left ventricular angiography and ascending aortic angiography as well as the transthoracic ultrasonography were performed immediately after the procedure to observe the therapeutic results. Follow-up checkups with transthoracic ultrasonography, EKG and chest X-ray film were conducted at one week as well as at one, 3, 6 and 9 months after the surgery were conducted. Results Successful occlusion of VSD was obtained in 93 patients, with a success rate of 96.8% (93/96). After the surgery, small amount of shunt flow was detected in 8 patients, which disappeared within 48 hours in 7 patients, and in the other one the shunt flow disappeared one month later which was confirmed by follow-up examination. After the treatment, complete right bundle branch block occurred in 4 patients, complete left bundle branch block in 5 patients, and transientⅢdegree atrioventricular block in one patient. The conduction block disappeared at the time of discharge in all patients. The left ventricular end-diastolic diameter (LVEDD) decreased from preoperative (47.5 ± 5.2) mm to postoperative (45.2 ± 5.1) mm, the difference was statistically significant (t = 18.33, P < 0.01). During the follow-up period lasting for 9 months, no delayed cardiac arrhythmia, valve damage or sudden death occurred. Conclusion For the treatment of perimembranous ventricular septal defect with pseudoaneurysm, interventional occlusion with thin waist occluder is safe and effective with excellent mid-term effect. Based on the imaging findings, including the location, shape, ruptured orifice, number of the perimembranous pseudoaneurysm as well as the distance between the pseudoaneurysm and the aortic valve, to select suitable occluder and proper occlusion site is the key to ensure a successful surgery.

ABSTRACT

Distribution and utilization of educational resource that were induced by multi-financing pattern became more and more important. This article plans to analyze the phenomenon of distribution and utilization of higher education resource at present on the basic functions of higher education, and discuss the problem about rationality of distribution and utilization of educational resource in the higher learning institutions.
