Active clinical trials for "Coronary Artery Disease"

International, multicentric, prospective, investigator-driven, open-label, randomized (1:1) clinical trial to observe and evaluate the efficacy, of Magic Touch Sirolimus Coated Balloon (SCB) compared to one of the gold standard treatment for native vessel disease (everolimus-eluting stent, EES).

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.

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 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.

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.

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.

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.

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 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.

Cigarette smoking causes cardiovascular disease (CVD) yet many smokers with CVD are unable to quit despite strong desire to do so. Within 90 days of discharge, about 30% of smokers have returned to daily smoking and almost 60% have relapsed by 1 year. Patients with CVD who resume smoking are more likely to experience new events (e.g. heart attack or stroke) or die. New approaches are required. A new type of cessation product is a plant-based medication called Cytisine. Cytisine is taken orally over 25 days and reduces the pleasurable sensations that smokers get from cigarettes and reduces withdrawal symptoms. The primary research question is whether or not it is feasible to conduct a large-scale trial of the effectiveness of this product compared to conventional nicotine replacement therapy in smokers who have failed to quit using conventional methods. To determine feasibility, a pilot study will be conducted of sixty smokers (30 men, 30 women) with CVD who have been treated for smoking cessation but have relapsed within 90 days of discharge. Participants will complete a baseline assessment and will be randomly assigned to either the combination nicotine replacement therapy group (patch plus lozenge) or cytisine group. Participants will be treated for 25 days and then will return to UOHI so adherence to treatment and smoking status can be assessed. Feasibility of the larger trial will be based on: the recruitment rates; adherence to assigned treatments; dropout rates; and differences in 25-day quit rates between groups.
