Active clinical trials for "Coronary Artery Disease"

Prospective clinical study with two parts: PART A: a prospective biomarker-based risk screening study in coronary heart disease (CHD) subjects PART B: a nested randomized clinical trial (RCT) in an enriched subpopulation of high-risk stable CHD subjects PART A: 12 000 subjects with stable CHD PART B: 2000 subjects with high risk of CV events will be randomized to usual care (UC) or personalised prevention program (PPP) i.e. 1000 subjects per arm. Study purpose is to assess the clinical value and cost-effectiveness of a personalised prevention program (PPP) in high-risk, stable coronary heart disease (CHD) subjects and to prospectively validate risk screening biomarkers

People with Coronary Artery Disease (CAD) have narrow or blocked arteries that supply blood to the heart. Reduced blood flow to the heart muscle from CAD can cause chest pain or aching, especially with exercise or activity. CAD can lead to weakening of the heart muscle or heart failure, and a higher risk of heart attack or death. Certain proteins in the blood, known as biomarkers, can be found in people with CAD. Higher levels of these biomarkers are associated with a greater risk of complications from CAD. The purpose of this study is to see if a customized treatment based on biomarkers will reduce the biomarker levels and lead to lower risk of complications from CAD.

This is a prospective, multi-center, randomized effectiveness trial of the CardioGard Embolic Protection Cannula in high-risk valve surgery patients.

Our objective is to find an effective prophylactic intervention by evaluating IV acetaminophen's impact in reducing the frequency of postoperative delirium, one of the most common and detrimental complications of cardiac surgery in older adults.

This study will recruit 400 participants who are taking part in the Computed Tomography Coronary Angiography for the Prevention of Myocardial Infarction (SCOT-HEART 2) trial. The investigator will assess diet, activity and habits at the start of the study and 6 months later. This will help us understand the effects taking part in the study may have on lifestyle. In addition, for participants who have CT scans, the investigator will present the results of the heart from the CT scan. This will help us understand how best to explain the results of the CT scan to patients.

Cardiac catheterization with invasive coronary angiography is the gold standard for determining the presence or absence of significant coronary heart disease (CHD). However, cardiac catheterization is costly and, as an invasive procedure, it is associated with some risk of adverse events, rarely even stroke, myocardial infarction, or death. Recent advances in multi-detector computed tomography angiography (CTA) have allowed rapid, noninvasive coronary artery imaging in patients with suspected CHD. CTA generally yields high accuracy for identifying patients with CHD when compared to cardiac catheterization. However, diagnostic accuracy is reduced in the setting of severe coronary artery calcification and coronary stents due to its inferior spatial resolution compared to cardiac catheterization. Because high-risk patients often have severe coronary calcification or stents, the application of CTA has been particularly limited in this important patient group. Recently, an ultrahigh-resolution CT scanner was released which has shown promise to overcome the limitation of conventional CTA in the setting of severe coronary artery calcification or stents. This ultrahigh-resolution "precision" CT scanner (UHR-CT) contains detector rows with half the width than currently available systems (0.25 mm vs. 0.5 mm) resulting in approximately twice the spatial resolution. The purpose of this investigation is to test the hypothesis that high-resolution CTA is not inferior to the current standard of cardiac catheterization for identifying significant CHD in patients with high-risk characteristics, including severe coronary artery calcification and coronary stents. The investigators propose to enroll 50 patients over 24-30 months in this investigation as part of a multicenter study. Patients referred for cardiac catheterization with known CHD and suspected obstructive coronary artery stenosis will be included. All patients will undergo both cardiac catheterization and UHR-CT for determining significant CHD as defined by coronary functional assessment. The primary end point will be the diagnostic accuracy by area-under-curve (AUC) method for identifying patients with hemodynamically significant CHD.

Adverse Childhood Experiences (ACEs) are potentially harmful events occurring during childhood that have been associated with chronic physical conditions in adulthood, including coronary artery disease (CAD). ACEs may constitute a portion of the remaining unexplained residual risk for CAD in adults. Identifying a means of addressing these experiences may mitigate their health consequences and result in improved cardiovascular outcomes. The primary objective of this study is to determine if patients who undergo ACE screening experience improved quality of life compared to patients who undergo conventional lifestyle assessment. This will be a single-centre, pragmatic, single-blinded (i.e. data analysts), 1:1, pilot randomized control trial.

This study aims to compare the effects of dexmedetomidine and meperidine on the incidence of shivering in patients undergoing CABG.

Percutaneous coronary intervention (PCI) remains the major revascularization strategy for patients with obstructive coronary artery disease (CAD).However,in a substantial number of PCI cases for acute coronary syndrome (ACS) and chronic coronary syndrome (CCS),periprocedural myocardial injury or myocardial infarction (MI) occurs,both these PCI-related complications may be associated with an increased risk of future major adverse cardiovascular events (such as death, re-infarction, and revascularization).The incidence of periprocedural myocardial injury varies according to the different definition and cardiac biomarker .For 4th UDMI criteria with hs-cTn, 78% to 85% patients who undergoing elective PCI may suffer from periprocedural myocardial injury. Experimental and clinical evidence highlight the abnormalities of the coronary microcirculation is one of the causes of myocardial ischemia.Coronary microvascular disturbances (CMD) have been associated with early stages of atherosclerosis even prior to any angiographic evidence of epicardial coronary stenosis, as well as to other cardiac pathologies such as myocardial hypertrophy and heart failure. In this study, we try to conduct a double blinded, randomized, placebo-controlled trial，the aim of our trial is: (1) to observe whether the prophylactically intracoronary administration of nicorandil and verapamil could reduce the occurrence of periprocedural myocardial injury and infarction in CAD patients undergoing elective PCI.;(2) to observe whether the prophylactically intracoronary administration of nicorandil and verapamil has protective effect on coronary microcirculation after elective PCI.

The aim of this non-inferiority trial is to determine if the distal radial access (DRA) during percutaneous coronary intervention (PCI) has an acceptable efficacy compared to the reference access through the conventional radial artery (TRA) with a lower rate of radial artery occlusion (RAO) in real life practice.
