Active clinical trials for "Arteriosclerosis"

The purpose of the SIROOP Registry is to retrospectively and prospectively collect baseline, clinical and procedural characteristics of patients who have undergone PCI and are treated with either currently available sirolimus or paclitaxel coated DCBs (see Table 1), irrespective of clinical presentation as well as to prospectively collect data about their clinical outcomes. Outcomes will be compared in different clinical subgroups. The impact of current DCBs in different clinical settings and coronary artery lesions on cardiovascular outcomes will be assessed.

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.

To assess the feasibility of coronary computed tomography angiography (CTA) and fractional flow reserve derived from CTA (FFRCT) to replace invasive coronary angiography (ICA) as a surgical guidance method for planning and execution of coronary artery bypass graft (CABG) in patients with 3-vessel disease with or without left main disease. The FASTTRACK CABG study is an investigator-initiated single-arm, multicentre, prospective, proof-of-concept, and first-in-man study with feasibility and safety analysis. Surgical revascularization strategy and treatment planning will be solely based on coronary CTA and FFRCT without knowledge of the anatomy defined otherwise by ICA that will be viewed and analyzed only by the conventional heart team. Clinical follow-up visit including coronary CTA will be performed 30 days after CABG in order to assess graft patency and adequacy of the revascularization with respect to the surgical planning based on non-invasive imaging with functional assessment and compared to ICA. Primary feasibility endpoint is CABG planning and execution solely based on coronary CTA in 114 patients. Primary safety endpoint based on 30-day coronary CTA is graft assessment either at the ostium, in the shaft or at the anastomoses of each individual graft either single or sequential. The FASTTRACK CABG study is the first study to assess safety and feasibility of planning and execution of surgical revascularization in patients with complex coronary artery disease, solely based on coronary CTA combined with FFRCT.

PräVaNet is a prospective, 1:1 randomized, controlled trial to investigate the efficacy of a new, digitalized prevention strategy ("ePrevention") in cardiovascular high-risk patients with type 2 diabetes mellitus in the outpatient sector.

The objective of this study is to evaluate the safety and effectiveness of the clinical and technical performance of the VRS100 system with disposable surgical kit in the delivery and manipulation of coronary guidewires and stent/balloon systems for use in percutaneous coronary interventions (PCI).

To undergo endovascular treatment of lower extremity arteriosclerosis obliterans After the subjects were selected and enrolled, the surgeons used the endovascular interventional surgical instrument control system developed by Shanghai Aopeng Medical Technology Co., Ltd. and the consumables of the endovascular interventional surgical instrument control system for the interventional hand Instrumentation (guide wire, catheter, stent, balloon) for remote delivery, manipulation, and withdrawal

Background. Atherosclerotic cardiovascular disease (ACVD) comprising coronary disease, cerebrovascular disease, peripheral artery disease, and aortic atherosclerosis caused 8.9 million deaths worldwide according to reports submitted by the World Health Organization during 2019, the development and progression of atherosclerosis is favored in the presence of modifiable risk factors such as dyslipidemia. In Mexico, during the period from December 29, 2019, to August 29, 2020, 141,873 deaths from heart disease were reported, even above the 108,658 deaths from SARS COV2 in the same time period. Although it is known that the Mexican mestizo population is susceptible to certain metabolic lipid disorders related to genetic variants, the frequency of dyslipidemia in patients with high cardiovascular risk is unknown to date and may be responsible for this increase. On the other hand, it has been shown that lowering LDL-C levels in this population by means of the pharmacological or dietary treatment stated the current guidelines, decreases chance of death, heart failure, angina, re-infarction or need for coronary revascularization; however, there are still patients not achieving treatment goals. Consequently, it is suggested that through the implementation and correct use of technological tools it is possible to increase efficiency in the medical follow-up of patients, allowing for appropriate lipid levels, like other chronic degenerative diseases such as diabetes and systemic arterial hypertension. Objective. To describe the frequency of dyslipidemias in high-risk and very high-risk patients with atherosclerotic cardiovascular disease, who are IMSS beneficiaries, and to analyze the impact of using an application to achieve dyslipidemia treatment goals at one-year follow-up. Hypothesis For the National Register: Not required since the main objective is to carry out a national register of dyslipidemias. For the use of the application: Null hypothesis: The use of the application does not change the frequency of patients with high and extremely high atherosclerotic cardiovascular risk who achieve the goals of dyslipidemia treatment during one year of follow-up.

Arteriosclerosis obliterans (ASO) is one of the most common peripheral artery diseases (PADs) which causes ischemic symptoms of the lower limbs. Endovascular treatment has emerged as the most commonly used and efficient treatment option for PAD. However, adverse cardiovascular and lower extremity outcomes are inevitable, which remains a challenge for the vascular surgeon. Pathologically, stenosis of the lower extremity arteries caused by arteriosclerosis has been regarded as the main cause of PAD. Lower extremity ASO is a chronic progressive disease caused by arteriosclerosis, which causes thickening of the intima of the feeding arteries of the lower extremity, lumen stenosis or occlusion, and insufficient blood supply to the diseased limb, resulting in intermittent claudication of the lower extremity, decreased skin temperature, pain, and even ulceration or necrosis. It is often the manifestation of systemic arteriosclerosis vasculopathy in the lower extremity arteries. ASO can be characterized by intermittent claudication, ischemic resting pain, and severe lower extremity ischemia. The main cause of lower limb ASO is atherosclerosis, and its incidence rises with age. The incidence of ASO in people over 70 years old is 15-20%, and the incidence of ASO in men is slightly higher than that in women. Known risk factors for lower extremity ASO include smoking, diabetes, hypertension, hyperlipidemia, hyperhomocysteinemia, chronic renal insufficiency, inflammatory indicators, etc. In terms of treatment, in addition to the treatment of cardiovascular risk factors such as lipid-lowering drugs, antihypertensive drugs, diabetes treatment, smoking cessation, antiplatelet and anticoagulant therapy, endovascular vascular revascularization is widely used at present. Many clinical centers choose endovascular therapy as the revascularization method of choice because of the lower incidence of complications and mortality compared with surgery, and the possibility of switching to open surgery if treatment fails. Luminal therapy is recommended when intermittent claudication affects quality of life, exercise or medical therapy is not effective, and clinical features suggest that endovascular therapy can improve the patient's symptoms and has a good risk benefit. There are many endovascular techniques for the treatment of lower extremity ASO, including percutaneous balloon dilatation, stent implantation, plaque resection, laser plasty, cutting balloon, drug balloon, cryoballoplasty, thrombolytic therapy with drugs or thrombectomy. At present, endovascular revascularization is widely used, but the incidence of adverse cardiovascular and lower extremity outcomes is still high, and the risk factors affecting the adverse outcomes after endovascular revascularization are still unclear. Therefore, the purpose of this study is to explore the risk factors affecting the poor outcome of endovascular revascularization for lower extremity ASO, and to provide precise prevention strategies for improving the prognosis of the patients. This study was designed as a single-center, prospective observational study. A total of 300 adult patients with lower extremity ASO who underwent endovascular revascularization in the Departments of Vascular Surgery and Peripheral Vascular in the First Affiliated Hospital of Xi 'an Jiaotong University were enrolled as the study cohort. The exclusion criteria includes patients with severe infections, tumors, liver and kidney failure, autoimmune diseases, and incomplete baseline data. Demographic characteristics, comorbidities, and serum biochemical parameters were collected before operation. The patients were followed up 1 year after operation. Follow-up included adverse cardiovascular events (cardiovascular death, acute myocardial infarction, stroke), lower extremity adverse events (resting pain, gangrene, amputation), and all-cause death. According to the estimation principle of multivariate COX regression for sample size, the minimum sample size of each group should be multiplied by the observed variable by 10-15, and the observed variable is estimated to be 10-15, so the minimum sample size of each group is estimated to be between 150-225, and the overall sample size is about 300. Multivariate COX regression analysis is used to analyze the influencing factors of poor prognosis in patients with lower extremity ASO undergoing endovascular revascularization.

Patients undergoing semi-elective lower extremity major amputation from complications associated with atherosclerotic limb ischemia will received intra-muscular injections of allogeneic Mesenchymal Stromal Cells in the leg above and below the point of amputation to prevent ischemic wound complications after surgery and decrease the incidence of revision and further amputation. Cohort Groups 1-4 will serve as controls.

The primary objective of this trial is to evaluate the long-term safety and efficacy of the NOVA intracranial drug-eluting stent system in "real world" patients with intracranial atherosclerotic stenosis.
