Atherogenic Index Of Plasma

Abstract Background The atherogenic index of plasma (AIP) always remains in a potential association with arterial stiffness, however, this association has not been fully discovered and needs to be studied in depth in large hypertensive patient populations. The present analysis thus sought to further explore the association that exists between AIP and arterial stiffness in Chinese patients diagnosed with arterial hypertension. Methods This cross-sectional study analyzed 4744 Chinese individuals with essential hypertension. AIP was defined as the base 10 logarithm of the ratio of plasma of triglycerides to high-density lipoprotein cholesterol levels indicated in molar concentrations. Measurement of arterial stiffness was carried out via brachial-ankle pulse wave velocity (baPWV). Results Data were adjusted for potential confounding variables, and multivariate linear regression analysis revealed AIP to be positively correlated with baPWV (β = 1.34, 95% CI: 0.96 to 1.72, P < 0.001). When AIP was instead treated as a categorical variable divided into quartiles, the same relationship was observed (P for trend < 0.001). We additionally found AIP and baPWV had a stronger positive association in individuals with a body mass index (BMI) < 24 kg/m2 (P for interaction < 0.05). Conclusion AIP and arterial stiffness were positively correlated in essential hypertension patients in China, especially in those with a BMI < 24 kg/m2. Clinical trial registration ChiCTR1800017274.

AbstractPast reports indicated that total-body irradiation at low to moderate doses could be responsible for cardiovascular disease risks, but the mechanism remains unclear. The purpose of this study was to investigate the association between radiation exposure and atherosclerosis, an underlying pathology of cardiovascular diseases, in the Japanese atomic bomb survivors. We performed a cross-sectional study measuring 14 clinical-physiological atherosclerosis indicators during clinical exams from 2010 to 2014 in 3274 participants of the Adult Health Study cohort. Multivariable analyses were performed by using a structural equation model with latent factors representing underlying atherosclerotic pathologies: (1) arterial stiffness, (2) calcification, and (3) plaque　as measured with indicators chosen a priori on the basis of clinical-physiological knowledge. Radiation was linearly associated with calcification (standardized coefficient per Gy 0.15, 95 % confidence interval: CI [0.070, 0.23]) and plaque (0.11, 95 % CI [0.029, 0.20]), small associations that were comparable to about 2 years of aging per Gy of radiation exposure, but not with arterial stiffness (0.036, 95 % CI [− 0.025, 0.095]). The model fitted better and had narrower confidence intervals than separate ordinary regression models explaining individual indicators independently. The associations were less evident when the dose range was restricted to a maximum of 2 or 1 Gy. By combining individual clinical-physiological indicators that are correlated because of common, underlying atherosclerotic pathologies, we found a small, but significant association of radiation with atherosclerosis.

The present analysis thus sought to further explore the association that exists between AIP and arterial stiffness in patients diagnosed with arterial hypertension in China.Methods: This cross-sectional study analyzed 4744 Chinese individuals with essential hypertension. AIP was defined as the base 10 logarithm of the ratio of plasma of triglycerides (TG) to high-density lipoprotein cholesterol (HDL-c) levels indicates as in molar concentrations. Measurement of arterial stiffness was carried out via brachial-ankle pulse wave velocity (baPWV).Results: Data were adjusted for potential confounding variables, after which a multivariate linear regression analysis revealed AIP to be positively correlated with baPWV (β = 1.34, 95% CI: 0.96 to 1.72, P < 0.001).

  Objective: Determine differences plasma levels MDA in preeclampsiabefore and 2 hours after delivery.   Methods: This was an analytic cross-sectional study. Subjectconsists of 23 pregnancies with preeclampsia, where 23 bloodsamples taken before delivery and 23 were taken 2 hours afterdelivery. This study was conducted from August 2016 untilDecember 2016 at Department of Obstetrics and GynecologyFaculty of Medicine Universitas Sam Ratulangi / Prof. Dr. R. D.Kandou Hospital Manado and satellite hospital. Samples weretaken from plasma and analysed using HPLC method at Prodiaclinical laboratory.   Results: In patients with severe preeclampsia before deliverywe found average value (1.4796  0.40819 nmol/ml), minimumvalue (1.03 nmol/ml) and maximal value (2.77 nmol/ml)and 2 hours after delivery with average value (1.2470 0.34324 nmol/ml), minimum value (0.91 nmol/ml), and maximumvalue (2.47 nmol/ml). by using Wilcoxon test, we foundthere were significant differences in plasma levels of MDA (p =0.000).   Conclusion: This significant difference suggests that decreasedplasma levels of MDA 2 hours after delivery and gives the sense thatthere is a relationship between oxidative stress of cells with severepreeclampsia before and shortly after delivery, that MDA is an indicatorof oxidative stress.   Keywords: malondialdehyde, oxidative stress, peroxidation lipid,preeclampsia
