Background: Vascular calcification is an independent determinant of cardiovascular events in maintenance haemodialysis (HD) patients. It is not known whether acute changes of the serum calcium concentration before and after HD (DeltaCa) are associated with the development of aortic calcification.
Methods: We enrolled 71 patients dialysed with a dialysate with 3.0 mEq/l calcium and determined their aortic calcification index (ACI) by abdominal computed tomography twice at an interval of 3 years. To identify the factors contributing to the rate of progression of aortic calcification, we analysed the average values for clinical and laboratory data obtained between the first and second evaluations of ACI.
Results: The second ACI (mean+/-SD: 80.2+/-63.9) was significantly greater than the first ACI (61.0+/-61.0) after an interval of 35.8+/-4.2 months. The annualized change of ACI (DeltaACI/year) was significantly and directly associated with the DeltaCa and C-reactive protein (CRP) (both P<0.001, P for trend). Stepwise multivariate regression analysis revealed that DeltaACI/year was positively and independently associated with CRP, presence of diabetes mellitus and DeltaCa, but negatively associated with a premenopausal status in women. Similarly, DeltaCa was positively and independently associated with DeltaACI/year and the ultrafiltration rate, but was negatively associated with pre-HD Ca.
Conclusion: The increase of serum calcium after HD was related to the rate of progression of aortic calcification. Excess calcium is transferred into patients on HD when using a dialysate of 3.0 mEq/l calcium. This may be a risk factor for the development of vascular calcification.

Aims: Less pronounced calcification of the aortic valve (AVC) was observed in women with aortic stenosis (AS) as compared to men. Since women have smaller aortic valves (AV), this could explain a lower calcium load. We aimed to analyze the association of AV size with AVC independent from sex.

Background: Abdominal aortic calcification (AAC) is considered as a strong predictor of cardiovascular disease (CVD) events. Our study aimed to investigate whether the predicted risk for cardiac death with the Framingham risk score (FRS) could be further improved with the addition of AAC score in general population aged ≥ 40 years.
Methods: A total of 2971 participants aged ≥ 40 years in the National Health and Nutrition Examination Surveys (NHANES) 2013-2014 were followed up.

Vascular calcification is considered to be a killer of the cardiovascular system, involved inflammation and immunity. There is no approved therapeutic strategy for the prevention of vascular calcification. Sinomenine exhibited anti-inflammatory and immunosuppressive effects.

Whether APOL1 high-risk variants are independent risk factors for cardiovascular diseases is unclear and requires further investigation.
Methods: We characterized a mouse model to investigate the role of APOL1 in dyslipidemia and cardiovascular diseases.

Background: Valve sparing aortic root replacement (VSARR) is a treatment for aortic root dilatation and aortic regurgitation (AR), which preserves the aortic valve. However, AR may recur, and redo surgery often carries high risk. Transcatheter aortic valve replacement (TAVR) can be performed but there is a paucity of literature to guide procedural planning.
