Active clinical trials for "Coronary Artery Disease"

This study aims to demonstrate that the BioFreedom™ Cobalt Chromium Drug Coated Stent is non-inferior to the market authorized BioFreedom™ Stainless Steel Stent with respective to efficacy and shows a similar safety profile.

The clinical investigation is a non-inferiority, multicenter, blinding evaluation, randomized, parallel controlled clinical study enrolling up to 440 subjects. All subjects will be randomized 1:1 to receive the BIOTRONIK Orsiro SES or the Abbott Xience Prime™ EES, in order to evaluate the efficacy and safety of the SES drug eluting stent in the treatment of coronary artery disease.

Percutaneous Coronary Intervention (PCI) is increasingly effective to treat Chronic Total Occlusion (CTO) lesions in coronary arteries. This trial will examine modern dissection and re-entry approaches to treat more complex CTO lesions with the Absorb Bioresorbable Vascular Scaffold (BVS).

This prospective multicenter registry evaluates the efficacy of hybrid coronary revascularization (HCR) combining coronary artery bypass surgery (CABG) and percutaneous coronary intervention (PCI) in the treatment of multivessel coronary artery disease. CABG is to be performed in the left anterior descending artery and the left circumflex artery using only arterial grafts, whereas PCI is to be conducted for the treatment of significant stenotic disease in the right coronary artery with everolimus-eluting stents (EESs). This research plans to involve patients scheduled for coronary revascularization for multivessel coronary artery disease who consent to participate in the registry.

This study aims to evaluate the efficacy and safety of traditional Chinese medicine DaZhu Rhodiola Rosea Capsule for treatment of coronary artery disease by observing angina symptoms, exercise capacity, and quality of life.

The objective of this randomized safety and observational study is to demonstrate CorPath GRX chronic total occlusion PCI is safe, and that Cardiac Catheterization Laboratory staff have no additional exposure to radiation when compared to conventional manual chronic total occlusion PCI procedures without added procedure time.

It is known that laughter can bring benefits in terms of physiological and psychological parameters, in addition to improving the individual's quality of life. However, the literature is still scarce as to the existence of studies investigating the effects of a comedy film specifically in hemodynamics.

This study intends to compare the combination of general anesthesia (GA) and single-shot bilateral thoracic paravertebral block (TPVB) by ropivacaine in the patients undergoing off-pump coronary artery bypass surgery ( OPCAB) with traditional general anesthesia (GA) perioperative management of patients, committed to reducing patient's physical and psychological stress by surgical trauma, achieve the purpose of fast recovery, in order to establish an more effective perioperative management during off-pump coronary artery bypass surgery, improve patients' satisfaction and to accelerate postoperative rehabilitation safely.

Current guidelines recommend the use of rotational atherectomy (RA) for preparation of heavily calcified or severely fibrotic lesions that cannot be crossed by a balloon or adequately dilated before planned stenting (bailout situations). RA emerged in the 1990s as one of several tools to treat luminal obstruction via physical removal of plaque. Although initially explored as an alternative to balloon angioplasty, RA has shown favorable acute results in facilitating stent delivery and adequate expansion, particularly those affected by heavy calcification.Drug-eluting stents (DES) have substantially reduced re-stenosis rates in randomized clinical trials evaluating simple de novo coronary artery lesions and have also shown favorable results when implanted in complex lesions and patients, but higher event rates are observed when treating such subsets compared with simple lesions even with newer generation DES. However, there are limited data on evaluating the safety and effectiveness of RA followed by DES implantation for heavily calcified lesions in contemporary practice. Recent randomized controlled trial shows that RA before paclitaxel eluting stent implantation as first generation DES was not superior to paclitaxel eluting stent implantation without prior RA in reducing the primary endpoint of in-stent late luminal loss at 9 months, indicating that RA does not increase the efficacy of DES in patients with moderate to severe calcified lesions. However, there were only 15 (12.5%) crossovers from standard therapy to rotablation because of failure of balloon or stent delivery or suboptimal balloon expansion despite the use of a noncompliant balloon. Accordingly, procedural and fluoroscopy times were longer in the elective RA and procedural complications occurred equally in both elective RA and bailout RA. These findings might cause by a substantial portion of enrolled population have moderate calcified lesions, but not severe calcified lesions. In particular, everolimus-eluting stent (EES) as newer generation DES could act synergistically in heavily calcified lesions as RA could avert stent coating damage and EES could effectively suppress neointimal proliferation. Therefore, we compare in-hospital and long-term efficacy or safety of elective RA versus bailout RA and low-volume operator versus high-volume operator in patients with severe calcified lesions treated with EES.

The purpose of this study is to conduct a single-center, randomized, open-label, controlled, dose-escalating, parallel-group study, evaluating the effects and change of endothelial function and gut microbiota after berberine administration in patients with stable coronary artery disease who are at > 8 but ≤ 40 weeks after elective percutaneous coronary intervention
