Filter by:This is a prospective and multicenter clinical investigation aiming to evaluate the safety and effectiveness of coronary intravascular lithotripsy system for the treatment of patients with coronary calcification.
Coronary revascularization interventions such as coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI) are the standard of surgical treatment of patients with myocardial ischemia. However, up to 30% of patients experience complications of varying degrees within 12 months after the revascularization, or need for second intervention. Thus, it is necessary to search for additional approaches to the postoperative treatment of patients in order to improve the long-term results of revascularization treatment. Substances of natural origin with an anti-atherosclerotic effect have a good potential. These substances, as dietary supplements, can be taken by patients for a long time in conjunction with other prescribed medicines and treatments. Another valuable direction of investigations is the search for predictors of long-term cardiovascular complications after revascularization, which can be markers of inflammation and heteroplasmy levels of the patient's mitochondrial genome. The purpose of this study is to determine whether the intake of dietary supplement Allicor at a daily dose of 300 mg affects the frequency of long-term postoperative cardiovascular complications and re-intervention in patients after revascularization operations on the coronary arteries. The second goal is assessing the relationship between the grade monocytes inflammatory response and the level of heteroplasmy of the mitochondrial genome of blood leukocytes with the frequency of cardiovascular complications and re-interventions.
The purpose of the RCT trial is to evaluate whether implantation of drug-eluting stent (DES) is more efficacious than bare metal stent (BMS) in prevention of in-stent restenosis (ISR) and improvement of outcomes for symptomatic intracranial atherosclerotic stenosis. This trial is prospective, multi-center, randomized 1:1 single blind trial using Maurora sirolimus eluting stent versus Apollo bare metal stent conducted in approximately 10 interventional neurology centers in China. The study is sponsored by Alain Medical (Beijing) Co., Ltd.
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.
Investigating the connection between delivered oxygen index and cerebral impact with COx (cerebral oximetry index) och cerebral injury markers during the routine use of cardiopulmonary bypass.
This study is a multicenter observational study designed to evaluate the the effectiveness and safety of drug-coated balloon (DCB) angioplasty for below the knee arterial lesions in patients critical with Limb Threatening Ischemia (CLTI).
The purpose of this study is to explore the effect of remote ischemic conditioning on the dynamic cerebral autoregulation in patients with intracranial and extracranial arteriosclerosis and the changes of dynamic cerebral autoregulation within 24 hours after remote ischemic conditioning.
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. ASO can be characterized by intermittent claudication, ischemic resting pain, and severe lower extremity ischemia. Known risk factors for lower extremity ASO include smoking, diabetes, hypertension, hyperlipidemia, hyperhomocysteinemia, chronic renal insufficiency, inflammatory indicators, etc. Endovascular 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. 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. The aim 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 500 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 at baseline. The patients were followed up 1-3 years after interventional therapy. Follow-up included adverse cardiovascular events (cardiovascular death, acute myocardial infarction, stroke), lower extremity adverse events (resting pain, gangrene, amputation), and all-cause death. Multivariate COX regression analysis is used to analyze the influencing factors of poor prognosis in patients with lower extremity ASO undergoing endovascular revascularization.
Coronary CT angiography is challenging in patients with more than mildly calcified coronary vessels, because of calcium artefacts that prevents evaluation of the lumen. The purpose of the CCT-PCD-1-study is to evaluate the diagnostic accuracy and image quality in coronary CT angiography using a commercially available CT system equipped with a photon counting detector technology. Patients referred for cardiac CT and conventional coronary angiography as part of routine preoperative evaluation before Transcatheter Aortic Valve Implantation (TAVI) will be asked for inclusion in the study. This group of patients has generally a coronary artery calcium burden and perform cardiac CT and coronary angiography as part of routine care. The diagnostic accuracy concerning significant coronary artery stenosis on the preoperative CT will be evaluated with the conventional coronary angiography as reference. Also, CT examination image quality will be evaluated.
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.
