Introduction: Aortic wall calcification increases arterial stiffness which is often assessed by carotid-femoral pulse wave velocity (cfPWV). However, the impact of kidney function upon the association between calcification of the aortic wall and cfPWV remains unknown. Methods: To examine the association between aortic calcification and cfPWV, we prospectively recruited chronic kidney disease (CKD) patients (estimated glomerular filtration rate [eGFR] <60 mL/min/1.73 m2) and patients with normal renal function, planned for invasive coronary angiography. Participants underwent a non-contrast computed tomography scan of the entire aorta with subsequent Agatston scoring of the aortic wall in addition to a standardized cfPWV measurement and biochemical markers. Results: A total of 144 patients (67.1 ± 10.3 years, 24% female), of whom 110 had CKD (26 stage 3a, 33 stage 3b, 24 stage 4, and 27 stage 5), were included. Agatston score was associated with cfPWV in a univariate regression analysis (p < 0.001). So were age (p < 0.001) and diabetes (p = 0.001), but not gender, smoking status, eGFR, office systolic blood pressure, calcium-phosphate product, C-reactive protein nor vasodilator treatment. Multiple regression analysis including all these factors did not significantly change these associations and relative weight analysis revealed Agatston score to account for 30% of the variation in cfPWV in the model (total r2 = 0.31). Conclusion: In a cohort representing the entire spectrum of kidney function, aortic Agatston score, as well as age and diabetes, were associated with cfPWV after adjustment for other risk factors including eGFR. However, most of the variation in cfPWV remains unexplained by these factors.

Introduction: Patients with chronic kidney disease (CKD) have an increased risk of cardiovascular morbidity. Circulating endostatin is associated with both cardiovascular morbidity and impaired kidney function in the…
Introduction: Age-related arterial remodeling is a key contributor to cardiovascular disease, but morphological changes in cerebral arteries with aging remain poorly characterized. We aimed to investigate age-related…
Introduction: Biological rather than chronological age (C-age) drives deviation from healthy aging. This study aimed to identify a plasma metabolomic signature indicative of age-related cardiovascular risk (pMTB-age)…
Introduction: Hypertension is linked to endothelial dysfunction, but causality and direction is not entirely known. The aim was to study the cross-sectional associations between home, office, and central BP and…
Introduction: Conventional systolic blood pressure (SBP) indices, such as mean SBP or variability indices, fail to capture control consistency. SBP time in target range (TTR) improves risk prediction by measuring SBP…
Introduction: While insulin resistance (IR) is an established risk factor for cardiovascular disease, vascular dysfunction represents a critical early pathological link. Although prior studies support the association…
Introduction: The association between indices of arterial stiffness and/or pressure wave reflection with Alzheimer disease amyloid-β accumulation and tau pathology in the brain is unclear. Deficiency of estrogen…
The distribution pattern of ABO blood group and Rhesus-D type varies in different parts of the Bangladeshi population. This study was carried out to determine the frequency of ABO and RhD blood group among all the…
Background: Dengue virus infection is one of the major public health concerns in Bangladesh. Recently, dengue is drastically spread out in all main cities as well as rural areas. There are four serotypes of dengue…
Metastasis to the thyroid gland from non-thyroid sites is an uncommon clinical presentation despite its rich blood supply. On the other hand, breast cancer frequently metastasizes to the bones, lungs, brain and liver…
