Active clinical trials for "Coronary Artery Disease"

This study is prospective, open-label, two-arm, randomized multicenter trial to evaluate the efficacy and safety of clopidogrel monotherapy as compared with aspirin monotherapy beyond 12 months after percutaneous coronary intervention (PCI) with drug-eluting stents (DES) in patients being treated with dual antiplatelet therapy (DAPT) at high risk for recurrent ischemic events.

The purpose of this study is to determine if ultrasound-guided bilateral pectointercostal fascial plane blocks with bilateral rectus sheath blocks block decrease pain scores, decrease opioid consumption, improve respiratory function, and improve quality of recovery in patients recovering from elective cardiac surgery involving primary median sternotomy and mediastinal chest tubes in comparison to pectointercostal fascial plane blocks alone.

The purpose of this study is to test the hypothesis that allogeneic Mesenchymal Stem Cells (MSCs) promote systemic and coronary endothelial repair through rescue of bone marrow progenitors in type 2 diabetic patients with symptomatic IHD compared to placebo.

The investigators hypothesize that preventive VT substrate ablation in patients with chronic ICM, previously selected based on imaging criteria (BZC mass) for their likely high arrhythmic risk, is safe and effective in preventing clinical VT events.

In a large number of patients who had a heart attack, multiple narrowings of the coronary arteries are identified. It is common practice to treat the narrowing that is the cause of the heart attack with a stent. It is not yet clearly known if the other narrowings in the other coronary arteries have to be treated immediately with a stent as well. "Bad" cholesterol (LDL-cholesterol) can speed up the formation of these coronary artery narrowings, and can thus make the risk of a second heart attack bigger. The investigators want to investigate if treating patients with the new cholesterol-lowering drug Evolocumab on top of the normal cholesterol lowering therapy (statins) ameliorates blood flow through coronary artery narrowings. Better blood flow through these narrowings could prevent the need for stenting or surgery in the future.

The INTERCLIMA (Interventional Strategy for Non-culprit Lesions With Major Vulnerability Criteria Identified by Optical Coherence Tomography in Patients With Acute Coronary Syndrome) is a multi-center, prospective, randomized trial of optical coherence tomography (OCT)-based versus physiology-based (i.e. fractional flow reserve[FFR]/instantaneous Wave-Free Ratio[iFR]/resting full-cycle ratio[RFR]) treatment of intermediate (40-70% diameter stenosis at quantitative coronary angiography), non-culprit coronary lesions in acute coronary syndrome (ACS) patients undergoing coronary angiography. About 1400 patients with ACS will be randomized into the study at approximately 40 sites worldwide.

The purpose of this study is to see if reducing the number of hours during which one eats each day will help reduce levels of LDL cholesterol and improve other markers of metabolic and cardiovascular health (i.e. blood sugar levels and blood pressure). The study also aims to assess changes in exercise capacity and trimethylamine N-oxide (TMAO) levels in response to Time Restricted Eating (TRE) and Intensive Cardiac Rehabilitation (ICR) versus ICR alone. TMAO is a metabolite, or a substance, produced during digestion and metabolism. Preliminary data illustrates a correlation between high levels of TMAO and higher risk of cardiovascular disease and mortality. We will also be looking at participants' long-term cardiovascular health status after they complete the ICR program.

This study aims to investigate the effect of transversus thoracis muscle plane block (TTP), using repeated boluses of ropivacaine via catheter, on postoperative pain and oxycodone consumption after elective cardiac surgery with sternotomy.

This is a multicenter, prospective, randomized, blinded, controlled clinical study in patients with planned primary valvular surgery and comorbid coronary artery lesions with diameter stenosis of ≥ 50%, to compare the effectiveness of an Quantitative Flow Ratio (QFR)-guided revascularization strategy and a coronary angiography (CAG)-guided revascularization strategy in preventing the incidence of composite outcome (MACE-5, including all-cause death, myocardial infarction, stroke, unplanned coronary revascularization, and new renal failure requiring dialysis) within 30 days after surgery. The study hypothesis is that the QFR-guided strategy can reduce the incidence of the MACE-5 within 30 days after surgery, as compared with the CAG-guided strategy.

The core hypothesis to be tested is that the radiosurgery of stellate ganglion (left one or both if left-sided without full relief of symptoms) is an effective therapy of refractory angina pectoris in patients with no other therapeutic options - proof of concept study.
