PUMCH Study Into Individualized Scanning for Coronary Artery Disease

COE
Start date: January 1, 2023
Phase:
Study type: Observational

Cardiac computed tomographic angiography (CCTA) is a non-invasive diagnostic imaging technique for visualization of the coronary arteries and thus, frequently used in the evaluation of coronary artery disease (CAD). CT technology is improving continuously, and various technological advances not only increase diagnostic accuracy, but also provide a substantial reduction in radiation dose and scan acquisition time. These modifications challenge optimal synchronization and timing of scan protocols in CM administration due to a shorter data acquisition window, hereby creating opportunities for injection strategies with a decrease in total amount of contrast media (CM). [4-6] Reducing the radiation dose of CT angiography and injected CM dose have become a routine need and trend in clinical practice. In addition to this, physical factors such as cardiac output and body weight are considered important factors with regard to variability in vascular enhancement. A standard 'one size fits all' protocol with a standard injected CM volume, independent of weight and length of the patient has proven to be outdated and precision medicine in the future should be based on individually tailored scan and CM injection protocols that are more scientific and involve various parameters such as individual tube voltage, patients weight and heart rate to benefit patients by reducing radiation exposure and CM dose while fulfilling the diagnostic purpose. Prospective studies focused on modifying both scan and injection parameters were completed in the Dutch (representing European) patient population with body weight varying between 40 and 130kg by Maastricht University Medical Center (MUMC) and have shown very promising results in Dutch population. In theory, these scan and injection protocols should be applicable to both average Dutch population (e.g. European population) and other heterogeneous patient populations, i.e. world-wide patient populations with any BMI category. However, so far, the effectiveness of this approach has not been deliberately discussed in the (on average) heavier North American population or the lighter Asian population. So, prior to promotion of the individually tailored CT scan protocols for global use, we need to obtain enough evidence in terms of the diagnostic confidence from those protocols in Chinese patients who could represent Asian population.

NCT ID: NCT05492110 Not yet recruiting - Coronary Disease Clinical Trials

Coronary Sinus Reducer Implantation in Patients With Ischaemia and Non-obstructed Coronary Arteries and Coronary Microvascular Dysfunction.

REMEDY-PILOT
Start date: August 6, 2022
Phase: N/A
Study type: Interventional

NCT ID: NCT05492084 Completed - Clinical trials for Atherosclerosis, Coronary

Personalized Risk of Rapidly Progressive Atherosclerosis

RPA
Start date: January 1, 2019
Phase:
Study type: Observational

Š’ackground. Progressive atherosclerosis is accompanied by unfavorable clinical outcomes, study and understanding of this process, creation of risk assessment method is necessary for individualization of approaches to treatment and prevention of this condition. Purpose of the study. Creation of a mathematical model to assess the risk of accelerated atherosclerosis development, using methods of factor and correlation analysis. Patient Characteristics and Study Methods. A retrospective cohort study included 202 patients with coronary heart disease. Group 1 included patients who had had myocardial infarction or unstable angina, emergency arterial stenting, stroke, peripheral artery thrombosis, critical ischemia, and lower extremity amputation within 2 years before study inclusion. Patients in the comparison group did not have these events. The influence of each of the studied parameters on the probability of fast progressing atherosclerosis was determined by factor and correlation analysis. The prospective part of the study will include follow-up of patients from both groups for 12 months. Annual "endpoints": fatal outcome, unscheduled coronary revascularization, nonfatal myocardial infarction and stroke, hospitalization due to unstable angina pectoris, stent thrombosis, stenting/plasty of lower limb arteries.

NCT ID: NCT05491668 Not yet recruiting - Clinical trials for Coronary Artery Disease

Physiological Assessment of Severe Coronary Stenosis for Informing Planned PCI

REFINE PCI
Start date: September 2022
Phase:
Study type: Observational

Traditionally, the severity of a blockage (stenosis) in a coronary artery has been determined by visual angiographic assessment of the diameter of the artery at the level of a blockage compared to a normal healthy area of the same artery. With the advent of invasive physiological testing to assess coronary blood flow, multiple clinical trials have demonstrated a clinical benefit to a physiology-guided percutaneous coronary intervention (PCI) approach. However, despite this and the potential for significant variation in the interpretation of coronary artery stenosis severity by visual angiography alone to guide PCI, invasive physiologic indices remain significantly under-utilized. The purpose of this study is to investigate the physiologic significance of coronary lesions deemed angiographically severe by visual estimation that are planned for PCI. The investigators plan to perform blinded physiologic assessment pre and post PCI. The primary aim of the study is to determine whether a subset of lesions visually estimated as severe by angiography treated with stent placement/PCI may in fact not be physiologically significant when assessed invasively, and thus PCI could safely be deferred in these patients. A secondary aim is to evaluate physiologic assessment post PCI to detect residual ischemia that could be utilized to optimize stent placement.
