NCT07444346
This study aims to investigate the efficacy and safety of intravascular lithotripsy (IVL) balloon in treating coronary calcified lesions at our center.
NCT05588895
This is a prospective randomized controlled trial assessing the impact of notifying patients and their clinicians of an incidental finding of coronary artery calcification (CAC) indicating increased cardiovascular risk. Patients will be identified through completed radiology orders for non-gated, non-contrast chest CT in the appropriate clinical context and then will have an EHR screen for inclusion criteria. The presence of CAC will be confirmed by a radiologist. Eligible patients will be randomized to CAC notification or usual care using a 1:1 stratified block randomization method based on baseline ASCVD.
NCT05259046
The purpose of this study is to examine the effect of menaquinone-7 (MK-7) supplementation on cardiovascular, metabolic, and bone health.
NCT07400406
This study is a single-center, prospective, controlled, diagnostic study. The study will be consecutive and is expected to enroll 100 patients with CCTA confirmed coronary calcified lesions. The purpose of this study was to compare the accuracy of novel Ferumoxytol-enhanced Cardiac Magnetic Resonance (Fe-CMR) and coronary CT angiography (CCTA) in detecting calcified coronary arteries, using coronary angiography (CAG) and optical coherence imaging (OCT) as gold standards.
NCT04253171
Severely calcified coronary stenoses are difficult to treat with percutaneous coronary intervention (PCI) using current techniques and there is little specific evidence on how to best treat these cases. It is hypothesized that balloon lithoplasty is superior to conventional balloons for lesion preparation of severely calcified coronary lesions before stent implantation in terms of procedural failure and 1-year target vessel failure.
NCT05444062
Does an educational intervention for untreated COPD and cardiovascular disease which is integrated in an existing lung cancer screening program improve guideline concordant medication adherence at 12 months
NCT05845424
The aim of this study is to compare safety and efficacy between the aggressive treatment with combination of high-intensity statin and ezetimibe and the current standard lipid lowering treatment in asymptomatic patients with presence of coronary calcification.
NCT06075602
The purpose of the COMPLEX Registry is to prospectively and retrospectively collect baseline, clinical and procedural data of patients who have undergone PCI or CABG for complex and/ or calcified chronic CAD, irrespective of clinical presentation as well as to prospectively collect data about their clinical outcomes. The outcomes will be compared in different clinical subgroups (e.g. PCI vs. CABG). The impact of current PCI techniques/ devices, but also CABG strategies in different clinical settings and coronary artery lesions on cardiovascular outcomes will be assessed.
NCT03920683
Diabetes is not a coronary risk equivalent, despite cardiovascular disease is the most common cause of death in diabetes. So, to identify diabetic patients at high cardiovascular risk is necessary. Coronary artery calcification score predicts major coronary events, and improves risk reclassification in asymptomatic diabetic patients. But, cornary artery calcification score is expensive and exposes patients to radiation. So, it cannot be used for large-scale screening. It could be interesting to identify the predictive factors of coronary artery calcification score. Toe-brachial index is relevant in diabetic patients for the screening of peripheral arterial disease, and predicts cardiovascular events. The aim of this study is to evaluate the association between toe-brachial index and coronary artery calcification score in asymptomatic patients with type 1 or 2 diabetes. The hypothesis is that toe-brachial index is associated with high coronary artery calcification score. It could be performed first to identify patients who require a coronary artery calcification score. It measurement is reliable, fully automated, repoducible ans cost-effectiveness. This is a cross-sectional study, with restrospective data collection. All patients addressed to a one-day hospitalization to assess cardiovascular comorbidities are eligible. Data are collected in patients'medical records. Clinical, biological and imaging data were collected previously during their one-day hospitalization
NCT05301218
Calcified lesions are very frequent among coronary artery disease stenotic lesions. The prevalence of calcifications ranges from 30 to 40% (by angiography evaluation) but is higher when analyzed by intra coronary imaging. Calcified lesions are very frequent among coronary artery disease stenotic lesions. The prevalence of calcifications ranges from 30 to 40% (by angiography evaluation) but is higher when analyzed by intra coronary imaging. The presence of calcifications increases the risk of adverse evolution after PCI , including stent restenosis, thrombosis and need for repeat revascularisation. Specific and appropriate tools can be used for calcified lesions management , including high pressure non compliant balloons, intravascular lithotripsy and rotablator. Intra vascular OCT has a high sensitivity and specificity for calcium detection among coronary artery lesions. Compared to IVUS, OCT allows a better quantification of calcium sheets (depth extension ) . Several intra coronary imaging based calcified lesions management algorithms have been proposed , but none have been validated in clinical practice.
NCT05112250
The IVL-Dragon Registry was a multicenter study that enrolled consecutive patients with stent underexpansion treated with IVL in high-volume PCI centers. The primary efficacy endpoint was clinical success, defined as a reduction of stent underexpansion to \<30% with no evidence of in-hospital device-oriented composite end point (DOCE) (defined as a composite of cardiac death, target lesion revascularization, and target vessel myocardial infarction).
NCT03314493
Vascular calcification is a frequent complication in dialysis patients and is strongly associated with mortality. Its pathogenesis is complex and involves a series of markers that act on the vascular microenvironment. There is evidence that aldosterone is one of the biomarkers and may have a role in osteoinductive pathways.The aim of this study was to evaluate the effect of spironolactone, an inhibitor of mineralocorticoid receptor, in the progression of coronary calcification in patients undergoing peritoneal dialysis.
NCT01992848
Coronary artery disease (CAD) remains the leading cause of mortality in the UK with an estimated 80,000 fatalities in 2010. Coronary artery calcification (CAC) is associated with atherosclerotic plaque burden and cardiovascular mortality. Mechanisms underlying isolated CAC have not been as yet been fully explained. MicroRNAs (miRNAs), known to act as regulators of gene expression, have also emerged as powerful biomarkers in the diagnosis and prognosis of cardiovascular disorders and may be used in the detection of CAC. We aim to investigate the potential for a "microRNA-signature" in patients with CAC by performing a prospective, case-controlled study to identify pathways associated with CAC in humans. Previous research has demonstrated an inverse relationship between CAC and bone mineral density (BMD), suggesting that these processes may be linked. In a further substudy we plan to define the relationship between CAC and BMD as well as a number of markers of bone metabolism.
NCT02498457
This study aim to observe the preventive effect and the long term safety of low calcium dialysis on coronary artery calcification in Maintenance hemodialysis (MHD) patients.
NCT00895427
This study examines the relationship between the SCOUT DM device and coronary artery calcification as determined by rapid computed tomography in patients at risk for coronary heart disease.
NCT01158066
Coronary artery disease are 8 times more prevalent in patients with NAFLD then the general population and are being considered the most common cause of death. Cardiac CT is a reliable non invasive method in demonstrating Coronary Plaques. However the association between coronary artery calcium score (CAC) and NAFLD remains controversial
