Filter by:The IVL Left Main study is a prospective non-randomised pilot study to investigate the mechanical and procedural outcomes and safety of distal left main stenting with coronary lithotripsy in addition to standard techniques in patients with calcific left main disease and a clinical indication for revascularisation.
This study evaluates the effect of Indobufen and Aspirin on platelet aggregation and long term prognosis in patients with stable coronary heart disease.
Low mobility is a mediator for poor outcomes of hospital care. Wearable devices will be used and 2-way texting via patient smartphones to monitor patients' physical activity during hospitalization with and without gamification to improve patient adherence to existing guidance on recommended activity. After discharge, investigators will assess patient care utilization (SNF, inpatient vs home rehab, ED visits, readmission) and conduct validated surveys on patient function at 30 days after discharge.
This study is a randomized, double-blind, placebo-controlled, parallel clinical trial in Chinese population with stable angina pectoris. The purpose is to determine the efficacy and safety of Xueshuanxinmaining tablet in the treatment of stable angina pectoris.
This study is a randomized, double-blind, placebo-controlled, parallel clinical trial in Chinese population with stable angina pectoris. The purpose is to determine the efficacy and safety of Yangxin Shengmai Granules in the treatment of stable angina pectoris.
This study is a prospective, multi-center single arm registry trial, planning to enroll 785 subjects. All subjects will receive clinical follow-up at 1 month, 6 month, 9 month and 1, 2, 3, 4, 5 year after index procedure. The primary endpoint will be target lesion failure (TLF) at 1 year after index procedure,which will be analyzed to evaluate the efficacy and safety of the device.
The purpose of this study is to analyze the changes in cardiac performance before and after milrinone administration in order to find out whether milrinone improves LV performance in patients undergoing coronary artery bypass surgery.
Patients with ischemic heart disease are often treated with multiple cardiovascular agents, including aspirin, statins, ezetimibe, Angiotensin Converting Enzyme (ACE) inhibitors or beta-blockers. Uncertainty about the optimal timing and clinical implications of administration of cardiovascular drugs still persists. The investigators will perform a pilot randomized trial to evaluate the efficacy and safety of a one daily administration of multiple drugs vs. twice daily administration.
In 1970, the first percutaneous balloon coronary angioplasty opened a new chapter of interventional therapy. However, the incidence of intracoronary restenosis was about 30%. Subsequently, bare metal stents and drug-eluting stents (DES) reduced the incidence of in-stent restenosis (ISR) to 5%-10% and it was still a bottleneck treated by percutaneous coronary intervention (PCI). Currently, ISR is mainly treated by balloon angioplasty, stent implantation and coronary artery bypass grafting. In 2014, the guidelines of the European Society of Cardiology recommended that drug balloon therapy (DCB) and new generation DES should be the preferred strategies for ISR treatment. Compared with DES, DCB treatment can avoid the inflammation of intima caused by multi-layer stent strut, and reduce the risk of intimal hyperplasia and thrombosis in stent. However, DCB lacks sustained radial support. Even if the residual stenosis is less than 30% after sufficient pre-dilation, the elastic retraction of the intima still exists. In addition, the antiproliferative effect of paclitaxel is significantly worse than that of sirolimus and its derivatives, and there is a lack of long-term sustained release of anti-proliferative drugs. Compared with DCB, DES can obtain long-term stable radial support and long-term anti-proliferation effect, but stent struts exposed in the vascular lumen are at risk of stent thrombosis. The new generation of DES improves the design of stent platform, improves the polymer coating, and applies new anti-proliferative drugs. It effectively reduces the inflammation of vascular wall, speeds up the process of vascular re-endothelialization, promotes early vascular repair, and significantly reduces the incidence of stent thrombosis. Recent BIOLUXRCT, RESTORE and DARE studies provide more powerful evidence for the treatment of ISR by new generation DES. Quantitative flow ratio (QFR) is the second generation FFR detectional method based on coronary contrast image. The latest FAVOR II results also confirm that QFR is more sensitive and specific than quantitative coronary analysis (QCA) in the diagnosis of myocardial ischemia caused by coronary artery stenosis. However, there is no report of ISR treated with DCB under the guidance of QFR. The aim of this study was to evaluate the safety and efficacy of DCB in the treatment of in-stent restenosis in patients with coronary heart disease (CHD) under the guidance of QFR compared with DES implantation.
correlation between EFT volume measured by Cardiac MRI and the angiographic severity of coronary artery disease (Syntax Score) in diabetic vs non diabetic CAD population and detect if there is a cut off value for each group that could predict higher risk.
