Active clinical trials for "Coronary Artery Disease"

Systematic metabolic diseases are closely related to prevalence and progression of atherosclerosis. This prospective cohort consecutively enrolls patients with coronary artery disease compliacted with metabolic abnormalities such as diabtetes, prediabetes, obesity, chronic kidney disease and hyperuricemia.

To evaluate the long-term clinical outcomes and prognostic factors in patients with coronary artery disease (CAD) undergoing invasive coronary angiography (ICA), intravascular imaging, or invasive physiologic assessment.

Investigating the diagnostic accuracy of online Ultrasonic Flow Ratio (UFR) assessment to identify hemodynamically significant coronary stenosis in patients with suspected ischemic heart disease using angiography-derived fractional flow reserve (FFR) as a reference standard.

This prospective multicenter observational cohort study is designed to study the diagnostic performance of acute-setting angiography-based FFR (e.g. vFFR) for the physiological assessment of intermediate non-culprit lesions in STEMI patients, with acute-setting FFR and acute-setting NHPR (e.g. RFR) as the reference standards.

This study is a prospective, multicenter study in the real practice to validate the diagnostic performances and clinical impact of coronary angiography & intravascular ultrasound (IVUS)-based models developed by machine learning (ML).

This is a prospective, multicenter, single-arm registry study, aimed to evaluate the clinical outcomes of using Shockwave IVL catheter in the treatment of coronary artery calcification in real-world clinical practice.

RESSURE-NIRS registry is designed to investigate clinical and pathophysiological characteristics of NIRS-derived lipid-rich plaque in patients with coronary artery disease. This is an on-going multi-center prospective registry in Japan.

The goal of this prospective observational study is to learn about in patients who need percutaneous coronary intervention for coronary artery disease. The main questions it aims to answer are: Fractional flow reserve according to coronary angiography findings after coronary artery balloon angioplasty Differences in fractional blood flow reserve before and after lesions between coronary balloon angioplasty using a scoring balloon and a regular balloon Participants will voluntarily consent to the study after being fully informed about the study and given ample opportunity to ask questions.

Lipoprotein(a) [Lp(a)] is a risk factor for cardiovascular events, although the underlying mechanism remains unclear. This study evaluated the relationship between Lp(a) and high-risk attributes (HRA) by coronary computed tomography angiography (CCTA) as well as their prognostic value.

Heart failure (HF) is an enormous health burden affecting approximately 5.1 million people in the US and is the cause of 250,000 deaths each year. Approximately 50% of HF is caused by myocardial ischemia and requires immediate restoration of coronary blood flow to the affected myocardium. However, the success of reperfusion is partly limited by intramyocardial hemorrhage, which is the deposition of intravascular material into the myocardium. Hemorrhagic reperfusion injury has high prevalence and patients have a much greater risk of adverse left ventricular remodeling, risk of fatal arrhythmia, impaired systolic function and are hospitalized at a greater rate. Recent magnetic resonance imaging techniques have improved assessment of reperfusion injury, however, the association between MRI contrasts and reperfusion injury is highly unclear, and lacks specificity to IMH. Improved imaging of IMH and accurate knowledge about its spatial and temporal evolution may be essential for delivery of optimal medical therapy in patients and critical to identify patients most at risk for adverse ventricular remodeling. The overall goal is to investigate the magnetic properties of hemorrhage and develop MRI techniques with improved specificity to hemorrhage. New MRI techniques permit noninvasive assessment of the magnetic susceptibility of tissues and can target tissue iron. Therefore, the investigators hypothesize that MRI imaging of myocardial magnetic susceptibility can map hemorrhagic myocardium. The investigators will perform a longitudinal observational study in patients after reperfusion injury to validate these methods, compare the methods with conventional MR contrasts and develop MR methods for imaging humans.
