Cerebral amyloid angiopathy (CAA) has been proven to be the most common pathological change in cerebral small vessel disease except arteriosclerosis. In recent years, with the discovery of imaging technology and new imaging markers, the diagnostic rate of CAA has greatly improved. CAA plays an important role in non-hypertensive cerebral hemorrhage and cognitive decline. This review comprehensively describes the etiology, epidemiology, pathophysiological mechanisms, clinical features, imaging manifestations, imaging markers, diagnostic criteria, and treatment of CAA to facilitate its diagnosis and treatment and reduce mortality.

Objective:To investigate the influencing factors of post-dialysis hypertension in maintenance hemodialysis (MHD) patients.Methods:This study was a cross-sectional and retrospective study. The patients receiving hemodialysis from January 9, 2017 to January 14, 2017 in 5 hemodialysis centers of Beijing area were selected. Post-dialysis hypertension was defined as an event characterized by an average increase of more than 15 mmHg in post-dialysis mean artery pressure (MAP) compared to intradialytic 3 h MAP during 3 consecutive hemodialysis sessions. Post-dialysis stable blood pressure was defined as an event characterized by an increase of less than 15 mmHg or a decrease of less than 10 mmHg in post-dialysis MAP compared to intradialytic 3 h MAP, with the exception of patients with post-dialysis hypertension and post-dialysis hypotension. The patients were divided into hypertension group and stable blood pressure group based on whether they had post-dialysis hypertension, and the differences of clinical data between the two groups were compared. The influencing factors of post-dialysis hypertension were analyzed by multivariate unconditional logistic regression.Results:A total of 491 MHD patients were enrolled in this study, including 65 patients (13.2%) in the hypertension group, 406 patients (82.7%) in the stable blood pressure group and 20 patients (4.1%) in the hypotension group. The age, blood calcium before dialysis and the proportion of patients using 1.75 mmol/L Ca 2+ dialysate in the hypertension group were higher than those of the stable blood pressure group, and pre-dialysis serum intact parathyroid hormone and pre-dialysis serum uric acid in the post hypertension group were lower than those of the stable blood pressure group (all P<0.05). The age, pre-dialysis serum intact parathyroid hormone, pre-dialysis serum calcium, pre-dialysis serum uric acid, dialysate Ca 2+ concentration of statistical differences between hypertension group and stable blood pressure group ( P<0.05), and post-dialysis serum calcium, pre-dialysis total serum cholesterol, application of β receptor blocker, gender of univariate analysis ( P<0.1) were included into the logistic regression equation as covariates. Multivariate logistic regression analysis showed that using 1.75 mmol/L Ca 2+ dialysate was the independent influencing factor of post-dialysis hypertension (with using 1.50 mmol/L Ca 2+ dialysate as reference, OR=2.930, 95% CI 1.282-6.694, P=0.011). The age and pre-dialysis serum calcium of statistical differences between hypertension group and stable blood pressure group ( P<0.05), and pre-dialysis serum sodium and pre-dialysis serum uric acid of univariate analysis ( P<0.1) were included into the logistic regression equation as covariates. The older age ( OR=1.046, 95% CI 1.000-1.093, P=0.049) and higher pre-dialysis serum calcium ( OR=21.847, 95% CI 2.111-226.075, P=0.010) were the independent influencing factors of post-dialysis hypertension when the 1.50 mmol/L Ca 2+ dialysate was used. Conclusions:The independent influencing factor of post-dialysis hypertension is using 1.75 mmol/L Ca 2+ dialysate, while the independent influencing factors of post-dialysis hypertension are the older age and the higher pre-dialysis serum calcium level when the dialysate Ca 2+ concentration was 1.50 mmol/L.
