Background: The high levels of serum calcium and cholesterol are the important risk factors of cardiovascular disease (CVD), which frequently influence each other during the development of CVD. However, few studies have examined their temporal relationship to confirm the precursor, and it is still largely unknown whether and how their temporal relationship would influence the development of CVD. This study aimed to establish the temporal relationship between the changes in serum calcium and cholesterol using the longitudinal cohort data, and examine whether this temporal relationship influenced the arterial elasticity indicated by brachial-ankle pulse wave velocity (baPWV).Methods: This is a cohort study with a sample of 3,292 Chinese participants (aged 20–74 years) with 5.7 years follow-up. Serum calcium and cholesterol were measured at baseline and follow-up survey. The cross-lagged path analysis was used to examine their temporal relationship, and mediation analysis was performed to evaluate the potential mediating effect.Results: The cross-lagged path coefficients (β2 values) from baseline serum calcium to follow-up cholesterol was significantly greater than the path coefficients (β1 values) from baseline cholesterol to follow-up serum calcium (β2 = 0.110 vs. β1 = 0.047; P = 0.010) after adjusting for the multiple covariates. The path coefficients from baseline serum calcium to follow-up cholesterol in the participants with high baPWV was significantly greater than the participants with low baPWV (β2 = 0.155 for high baPWV and β2 = 0.077 for low baPWV, P = 0.028 for the difference between the β2 values). Moreover, cholesterol partially mediated the association between the higher serum calcium and greater subsequent baPWV values, the percentage of the total effect mediated by cholesterol was estimated at 21.7%.Conclusion: Our findings indicate that increased serum calcium precedes increased in serum cholesterol, and this temporal relationship may contribute to the development of higher baPWV levels.

Abstract Background and Aims Fluid overload and vascular stiffness are two independent predictors of cardiovascular events in hemodialysis (HD) patients. To date, observational and interventional studies that investigated the effect of inter- and intradialytic fluid overload changes on vascular stiffness in HD patients are very limited. We performed a scoping review to explore existing reports about effects of fluid overload on vascular stiffness in adults receiving HD treatment and to identify knowledge gaps for future research. Method We followed the framework originally developed by Arksey and O’Malley. We searched Medline, Embase, CINAHL, and Cochrane Database of systematic reviews from inception to October 29, 2019. References of review papers were screened for relevant studies not identified from the initial search until saturation is achieved. Results Of 666 eligible studies, nineteen studies met the inclusion criteria. These included clinical observational studies (n=16) and randomized controlled trials (n=3). In general, most of the identified studies had small sample size and short term of follow up. Studies use different definitions of fluid overload and vascular stiffness. Measures of relative fluid overload like the ratio of extracellular fluid/intracellular fluid, fluid overload/extracellular fluid, and/or extracellular fluid/total body fluid were used as a representative of fluid status. Pulse wave velocity and augmentation index were used interchangeably as vascular stiffness measures. The accumulated findings were inconsistent and inconclusive. There was no consensus whether intradialytic fluid volume changes affected vascular stiffness. In the majority of the observational studies, a decrease in pulse wave velocity or augmentation index correlated with a decrease in blood pressure after fluid correction by HD treatment. The randomized clinical trials used different methods and technologies for the correction of fluid overload, thereby, results were conflicting. Conclusion Current literature is insufficient to justify whether fluid overload changes have a direct effect on vascular stiffness in HD patients. The findings were conflicting which limits the comparisons of studies and generalization of findings. These knowledge gaps urge the need for further clinical studies to enhance the understanding and to improve the quality of research in this topic. This includes standardized definitions and methodologies as well as longer term of follow up.

Biofeedback Treatment

In a study undertaken to evaluate the clinical effectiveness of two behavioral treatments for essential hypertension (biofeedback on arterial pulse-wave velocity and progressive relaxation) 24 hypertensive subjects were randomly assigned to either a relaxation or biofeedback treatment group for 5 weekly sessions. In a second stage of the study 16 of the original subjects received both biofeedback and relaxation treatments during 5 additional weekly sessions. Results indicated that biofeedback and relaxation were equally effective in initial lowering of blood pressure in hypertensives. Although biofeedback training led to superior reductions at the 3-mo. follow-up point, after 1 yr. the blood pressures of both groups were not only equal but well below those presented at the beginning of the study.

Aim: to assess the relationship of changes in pulse wave velocity (PWV), a marker of target organ damage, with the variation in BP over time, as assessed by three different methods of measurement: office and 24h-ambulatory peripheral BP as well as aortic BP. Methods: Observational prospective study in hypertensive subjects with impaired glucose metabolism consecutively recruited from Spanish Hypertension Units. Aortic BP and carotid-femoral PWV were evaluated by radial applanation tonometry (Sphygmocor®) at baseline ( b ) and after 12 months of follow-up ( fu ). Peripheral BP measurements were also recorded at baseline and at 12 months follow-up: office BP was obtained as the average of triplicate measurements taken at 1 min-intervals after 5 min of seated rest, using validated oscillometric devices; 24h-ambulatory BP recordings were taken with a validated device (Spacelabs®-90207) at 20-minute intervals throughout both the self-reported awake and asleep periods. Clinical and anthropometric features were also recorded. PWV variation (Δ) over time was calculated as follows: Δ PWV= [(PWV fu - PWV b ) / PWV b ] x 100. BP variation over time was calculated with the same formula applied to BP values obtained with the different measurement techniques. Correlations (Spearman “Rho”) of Δ PWV and Δ BP were calculated. Results: n=209 patients; mean age: 61.8 ± 11.2 y; 39% (81 of 209) were female; 80% (167 of 209) had type 2 diabetes. Other risk factors: hypertension: 100%; dyslipidemia: 69% (144 of 209); smokers: 13% (28 of 209); body mass index: 30.9 ± 4.4 Kg/m 2 . Baseline office systolic/diastolic BP (mmHg): oSBP = 143 ± 20; oDBP = 82 ± 12. Follow-up office systolic/diastolic BP (mmHg): oSBP = 136 ± 20; oDBP = 79 ± 12. Baseline PWV: 10.01 ± 3.5 m/s. Follow-up PWV: 10.19 ± 3.21 m/s. Δ PWV correlated with: Δ oSBP (Rho=0.212; p=0.002), Δ 24h-SBP (Rho=0.254; p<0.001), Δ daytime-BP (Rho=0.232; p=0.001), Δ nighttime-BP (Rho=0.320; p<0.001) and Δ aortic-SBP (Rho=0.320; p<0.001). Conclusion: Modification over time of PWV, a marker of target organ damage, parallel to changes in systolic BP, both office and 24h-ambulatory peripheral BP variation as well as aortic BP variation, at 12 months of follow-up. Among them, aortic SBP and nighttime peripheral SBP both showed the best correlation.

Abstract Objectives Assessment of carotid-femoral pulse wave velocity by applanation tonometry independently predicts all-cause and cardiovascular mortality. However, there has been a need for a simpler, user-independent measurement with a validated device, that is applicable even in the primary care setting. Methods and subjects 4146 subjects (49% men) aged 35–75 years were measured in multiple centers in Hungary. Subjects visited the outpatient department of these centers on their own initiative. The measurement of aortic pulse wave velocity (PWVao) with Arteriograph was performed in addition to taking past medical history, physical examination and laboratory tests. The mean follow-up time of the study was 5.5 years. The number of events (all cause mortality) were provided by the Hungarian National Health Insurance Fund. Cox regression analyses were used to identify predictive factors for this endpoint. Results The mean age of the study population was 53 years, brachial systolic and diastolic blood pressure were 137±20 and 82±11 mmHg, and heart rate was 70±10 1/min. The mean value of SCORE was 3 in this large cohort. 410 subjects had a registered cerebro-or cardiovascular event before the measurement, the number of smokers was 656 (16%), 1974 subjects were treated with at least one anti-hypertensive drug (48%), while the number of subjects on lipid-lowering, antidiabetic or antiplatelet medication were 807 (19%), 352 (8%) and 398 (17%), respectively. There were 116 fatal events during a mean follow-up of 5.5 years. According to the Cox regression, PWVao is a significant and independent predictor of all cause-mortality and in univariate analysis, a 1.0 m/s increase in PWVao was associated with HR 1.7 [1.47–1.98; p<0.001], for this endpoint. Conclusion Aortic pulse wave velocity measured by an invasively validated, simple, oscillometric device predicted all-cause mortality in a large cohort of relatively young subjects of the general population that may improve risk stratification even in the everyday clinical practice or primary care setting.
