NCT ID: NCT04794868 Active, not recruiting - Clinical trials for Acute Coronary Syndrome

Prediction and Validation of Clinical Course of Coronary Artery Disease With CT-Derived Non-Invasive Hemodynamic Phenotyping and Plaque Characterization

Start date: April 1, 2020
Phase:
Study type: Observational [Patient Registry]

Acute coronary syndrome (ACS) and sudden cardiac death can be the first manifestation of coronary artery disease and are the leading cause of death in the majority of the world's population. The main pathophysiology of ACS is well-known and fibrous cap thickness, presence of a lipid core, and the degree of inflammation have been proposed as the key determinants of plaque vulnerability. Previous studies using virtual histology intravascular ultrasound or optical coherence tomography showed that clinical application of this concept improved risk prediction of ACS. However, these approaches have not been widely adopted in daily practice due to relatively low positive predictive values, low prevalence of high-risk plaques and the invasive nature of diagnostic modalities. Non-invasive imaging studies with coronary computed tomography angiography (CCTA) also showed the clinical value of CCTA-derived high risk plaque characteristics (HRPC). In addition, the recent progress in CCTA and computational fluid dynamics (CFD) technologies enables simultaneous assessment of anatomical lesion severity, presence of HRPC and quantification of hemodynamic forces acting on plaques in patient-specific geometric models. As plaque rupture is a complicated biomechanical process influenced by the structure and constituents of the plaque as well as the external mechanical and hemodynamic forces acting on the plaque, a comprehensive evaluation of lesion geometry, plaque characteristics and hemodynamic parameters may enhance the identification of high-risk plaque and the prediction of ACS risk. In this regard, the current study is designed to evaluate prognostic implications of comprehensive non-invasive hemodynamic assessment using CCTA and CFD in the identification of high risk plaques that caused subsequent ACS.

NCT ID: NCT04791592 Active, not recruiting - Clinical trials for Coronary Artery Disease

Pecto-Intercostal Fascial Block vs. Transversus Thoracic Muscle Plane Block in Cardiac Surgery

Start date: March 12, 2021
Phase: N/A
Study type: Interventional

In patients undergoing open cardiac surgery, pain control is an essential part of the enhanced recovery process. The current study aimed to evaluate the analgesic efficacies of ultrasound-guided pecto-intercostal fascial block and ultrasound-guided transversus thoracic muscle plane block for open cardiac surgeries. Analgesic efficacy will be assessed on the numeric rating scale (NRS) along with intraoperative and 24 h postoperative opioid consumption.

The aim of this study is to examine the effect of secondary prevention education given to individuals after acute myocardial infarction on physiological parameters, anxiety and quality of life.

NCT ID: NCT04715594 Active, not recruiting - Clinical trials for Coronary Artery Disease

CONNECT DES Registrty

Start date: August 11, 2019
Phase:
Study type: Observational

To date, drug-eluting stents (DES) have become the standard of care in daily practice for the treatment of ischemic heart disease, by overcoming the risk of in-stent restenosis, a major issue raised in the bare-mare stents era. The application of potent anti-proliferative drugs and polymer structures that ensures sustained released of the drugs markedly reduced the neointimal hyperplasia, leading to much improved clinical outcomes compared with bare-metal stents. However, although first-generation sirolimus-eluting stents and paclitaxel-eluting stents significantly reduced the risk of in-stent restenosis and target-vessel revascularization, an augmented risk for very late stent thrombosis and fatal clinical events emerged as a new issue to be solved. Second- and newer- generation DESs adopted innovative stent platforms, novel stent materials, anti-proliferative drugs, and biocompatible polymers (including both durable and bioresorbable). Nowadays, numerous types of DESs (over 20 types) are available in clinical practice as well as bare-metal stents. However, little is known about the clinical outcome according to type of DESs in real-word practice. Given that many of recent randomized clinical trials (RCTs) demonstrate the 'non-inferiority' of brand-new DESs over older DESs in limited period time (usually for 1-year) in a selected patients eligible for RCTs, the real-world clinical outcomes according to type of DES implanted are still unveiled. Although, the question about the differential impact of generation of DES, type of biocompatible polymers (bioresorbable versus durable), thickness of stent struts and type of eluted anti-proliferative drugs are very important in clinical aspect of view, but there is little study conducted on all patients who are actually confronted in daily clinical practice. Korea operates national insurance system that covers most of the Koreans (97.1%) that are strictly monitored by National Health Insurance Service (NHIS). Of note, the claims database of NHIS of Korea contains all information including the demographic characters of patietns, diagnosis codes (ICD-9 and ICD-10), type of procedures or surgeries and the medical devices utilized, death certificates that contains type of death, and the drugs prescribe in outpatient clinic and hospitals in a individual pill level, that enables monitoring for the drug compliance. This unique feature of NHIS database allows the investigators to gain access to the dose and duration of cardio-protective medications including anti-platelet agents, lipid-lowering agents, anti-hypertensive agents, glucose-lowering agents, nitrate donors, vasodilators, and others. Given the benefits of NHIS database of Korea, we would like to establish a whole-population registry, named as COreaN NationwidE Claims daTa on Drug-Eluting Stent Registry (CONNECT DES Registry). A comprehensive analysis of this data is expected to shed new light on the impact of type of DESs and drug use in real-world practice that could be fully revealed through RCTs.

NCT ID: NCT04453267 Active, not recruiting - Clinical trials for Coronary Artery Disease

DNA Repair in Patients With Stable Angina.

DECODE II
Start date: February 5, 2020
Phase:
Study type: Observational

Markers of DNA damage and repair are present in both atherosclerotic plaques and peripheral blood mononuclear cells of patients with coronary artery disease. A positive correlation has been observed between the level of DNA damage and the severity of atherosclerotic lesions, as well as atherogenic risk factors such as smoking, hypertension and hyperlipidaemia. A number of in-vitro studies have implicated defective DNA repair in the development and progression of atherosclerotic lesions. In mouse models of atherosclerosis, the DNA repair signalling cascade has been shown to be amenable to pharmacological intervention and overexpression of specific repair proteins attenuate the development of atherosclerotic plaques. However, data regarding the role of DNA repair in the pathogenesis of atherosclerosis in humans are lacking. We have preliminary data indicating reduced DNA repair activity in patients with stable angina. This study will determine the molecular basis and the biological consequences of this observation.
