In calcified lesions, optimal stent placement and expansion may prove to be challenging. Lesion preparation is necessary to facilitate optimal stenting in calcified lesions, for which orbital atherectomy can used. Therefore the aim of this study is to: 1. Show that orbital atherectomy effectuates optimal stent expansion 2. Investigate the mechanics of lesion preparation when using orbital atherectomy Patients presenting with a significant and severely calcified lesion in need of orbital atherectomy will undergo optical coherence tomography guided orbital atherectomy and stent placement.
The goal of this observational study or clinical trial is to learn about the effect of neutrophil gelatinase-associated lipocalin (NGAL) on vascular calcification in maintenance hemodialysis patients with secondary hyperparathyroidism (SHPT). The main question it aims to answer is: the predictive effects of blood NGAL level on the efficacy of palicalcitol in the treatment of SHPT and the adverse reactions of vascular calcification progression. Participants will be treated with palicalcitol, followed up and undergo routine series of Chronic Kidney Disease-Mineral and Bone Disorder associated tests before and after treatment.
Cardiovascular disease (CVD) represents the leading cause of death worldwide. While medications, such as statins, significantly reduce atherosclerotic CVD (ASCVD) risk by lowering low density lipoprotein levels, they may also have pleiotropic effects on inflammation. The immunomodulatory effects of these medications are relevant to ASCVD risk reduction given that inflammation plays a central role in atherosclerotic plaque formation (atherogenesis) and influences the development of vulnerable plaque morphology. Patients on statins, however, may have residual inflammation contributing to incident ASCVD despite the potent LDL-lowering effects of statins. While new therapies, such as proprotein convertase subtilisin/kexin type 9 (PSCK9) inhibitors, further reduce incident ASCVD and drastically reduce LDL-C below that achieved by statin therapy alone, PCSK9 inhibitors may also have pleiotropic effects on inflammation. Thus, PCSK9 inhibitors may help reduce arterial inflammation to a level closer to that of patients without ASCVD. This study will apply a novel targeted molecular imaging approach, technetium 99m (99mTc)-tilmanocept SPECT/CT, to determine if residual macrophage-specific arterial inflammation is present with statin therapy and the immunomodulatory effects of PSCK9 inhibition. Given the continued high mortality and morbidity attributable to ASCVD, strong imperatives exist to better understand the immunomodulatory effects of lipid lowering therapies and residual inflammatory risk. This understanding, in turn, will inform the development of new ASCVD preventative and treatment strategies as well as elucidate other indications for established therapies.
The objective of this clinical investigation is to evaluate, in a controlled setting, the 12 months safety and efficacy of the combination of Shockwave Intravascular Lithotripsy and a polymer coated Drug Eluting Stent device, for PACSS 3 and PACSS 4 calcified femoropopliteal disease.
The purpose of this research study is to determine the potential benefits of adding information on patients' breast arterial calcification (BAC) results to the standard results letter women receive after mammography. In addition to looking for potential breast cancer, research shows that mammograms can also detect the presence of calcifications within the breast arteries. Those calcifications can be associated with coronary artery disease. Right now, women are not routinely told whether or not they have BAC; that is, it's not part of standard practice to communicate that information to patients. However, previous research has suggested that patients would like to be informed about their BAC status more often. In this study, the team has two goals. First, the team wants to measure the rates of BAC in a large, diverse group of 14,875 women. Because most of the past research on BAC has largely been focused on White mammography patients, the researchers feel it is important to see if the results are similar or different in a more racially and ethnically diverse sample. Second, the study team wants to understand the effects of giving women information on their BAC results as part of their standard post-mammography letter. Specifically, the study team wants to see how sharing that information might affect women's healthcare choices and lifestyle. The research will include 1,888 women in this second part of the study, which will be the first in the literature to explore women's reactions to BAC information. If research shows that women find the information useful, BAC information may be given to women regularly in the future.
Coronary artery calcification (CAC) is a common complication of type 2 diabetes mellitus(T2DM), which can significantly increase all-cause mortality and the incidence of serious cardiovascular events, and increase the burden of the national economy. The epidemiological characteristics and the clinical progress of CAC are still not clear. Moreover, the pathogenesis of CAC has not yet been fully elucidated, and lack of specific diagnostic indicators. Arterial calcification is an active, reversible, and multifactorial biological process like bone formation. It is generally believed that early detection of calcification lesions and active targeted treatment may be the key to prevention and treatment of vascular calcification. In addition, statins are commonly used in patients with dyslipidemia and can stabilize CAC plaque. However, the timing, dosage and effect of statins are controversial. Moreover, our previous study found that the expression of miR-32 is significantly elevated in patients with CAC, and can promoting vascular calcification. Herein, this study is to conduct a prospective cohort study on T2DM patients with CAC in Hunan province through a multidisciplinary and multi-center cooperation model, the main research objectives include the following three parts: ① To identify the prevalence, incidence, and characteristics of CAC in T2DM patients in Hunan province, and to build a risk assessment model. ② To observe the effects of statins on the occurrence and development of CAC in patients with T2DM, and to provide clinical data for the improvement of medication guidelines; ③To observe the dynamic changes of serum miR-32 in the progression of CAC in patients with T2DM, and to explore its possibility as a serological diagnosis or prognostic bio-maker of CAC. The completion of this research project is expected to bring a new breakthrough in the field of early diagnosis, prognosis evaluation, and intervention treatment of patients with T2DM combined with CAC, and provide an important reference for the formulation of cardiovascular disease prevention and control strategy.
Although it is now established that calcification process result from the joint and coordinated action of different cell types, many areas of shadow remain regarding the spatio-temporal implementation of these events. Highlighting these processes requires additional research to consider new approaches to clinical management of patients with such conditions. It is in this context that the investigators need to use residual human tissue fragments resulting from surgery which are not intended to be used for clinical-biological management of patients. The use of these pseudonymised human tissues will allow the investigators to conduct in vitro cell culture experiences.
The investigators project is based on: - Assessment of bone architecture by high resolution peripheral scanner (HRpQCT) and bone densitometry (DEXA); - The non-invasive detection of vascular calcifications (by abdominal CT scanner) and bone abnormalities associated with kidney transplantation, as well as the analysis of evolution over time; - Longitudinal evaluation of nephrological clinical parameters (glomerular filtration rate, number and type of rejections, immunosuppressive medications) as well as biological and urinary parameters of mineral metabolism (parathormone, sclerostin, bone alkaline phosphatase) depending on the type and severity of bone abnormalities; - The evaluation of these nephrological clinical parameters and of the biological parameters of mineral metabolism depending on the extent and evolution of vascular calcifications but also on bone morphology; - The study of possible relationships between bone mass and muscle mass (and functioning)
The aim of this study is to assess the effect of supplementation of vitamin K2 (menaquinone, MK-7) and cholecalciferol (inactive vitamin D) on circulating levels of calcification regulators and to assess their safety in pediatric patients on regular hemodialysis patients.
