CMR Versus CT in Coronary Artery Disease
CONCORD is a prospective observational study evaluating the diagnostic accuracy of cardiovascular magnetic resonance (CMR) and computed tomography with fractional flow reserve (CT-FFR) in patients with suspected coronary artery disease, using invasive fractional flow reserve (FFR) as the reference standard.
MAIN-IMAGE Registry
All comers registry with patients with chronic coronary syndrome or acute coronary syndrome who underwent intracoronary imaging during cardiac catherization. The aim is to identify plaque characteristics on OCT or IVUS that are associated with adverse cardiac events including myocardial infarction and atherosclerotic progression.
Vascular Senescence and Atherosclerotic Plaque Vulnerability
Chronological aging significantly contributes to structural and functional alterations in the vasculature, making it a major risk factor for atherosclerotic disease and its acute thrombotic events. DNA damage, including telomeric, non-telomeric, and mitochondrial damage, is recognized as a key initiator of vascular aging and atherogenesis. There is abundant evidence indicating …
Clinical and Angiographic Outcomes of Post-drug-coated Balloon Angioplasty in Native Coronary Lesions
The progression of cardiac revascularization techniques, starting with standard balloon angioplasty (POBA) and progressing to the creation of drug-coated balloons (DCB) and drug-eluting stents (DES). The study's justification is presented, with a focus on the significance of comprehending the clinical and angiographic outcomes of DCB angioplasty, especially when considering the …
Latvian Early Atherosclerosis Registry
Atherosclerosis and its complications are a global problem. There are several widely known and proven risk factors that promotes atherogenesis in the majority of patients. However, significant proportion of apparently healthy and young patients with cardiovascular disease but yet without recognized atherogenesis promoting risk factors can be observed in clinical …
Coronary Evaluation And Guided Lesion Exploration Using Photon-counting CT and Intracoronary Imaging Techniques
This study evaluates the diagnostic accuracy and limitations of photon-counting computed tomography (PCCT) in characterizing coronary plaque, with comparisons to optical coherence tomography (OCT) and intravascular ultrasound (IVUS). The objective is to assess whether cardiac ultra-high resolution (UHR) PCCT -with its improved spatial resolution and superior soft tissue contrast relative …
Single-cell Multi-omics Analyses of OCT-diagnosed Plaque Subtypes in Coronary Artery Disease (MOOP-CAD)
The MOOP-CAD study program characterizes, for the first time, the pathophysiological processes and molecular mechanisms of coronary atherosclerotic plaque progression by combining in vivo intravascular imaging techniques with circulating immune single-cell multi-omics analysis. In this study, the investigators evaluate the imaging characteristics of coronary plaques by optical coherence tomography (OCT) …
Relationship Between Coronary CT Angiography Findings and Prognosis Of Patients Undergoing PCI
Researchers at Cerrahpaşa Medical School in Istanbul are studying how a heart imaging test called coronary CT angiography can help improve care for people with coronary artery disease. This disease happens when fatty buildups, known as plaques, form in the arteries that supply blood to the heart. Over time, these …
Residents' Learning Curve of Intraoperative Transit-time Flowmetry and High-frequency Ultrasound in CABG (LEARNERS)
Transit-time flowmetry (TTFM) allows grafts quality assessment during coronary artery bypass surgery by measuring the flow volume through them. Recently the intraoperative epicardial high-frequency ultrasound (HFUS) was introduced, with the possibility of capturing bidimensional images of the anastomoses. When combined, these two techniques provide high diagnostic yield reaching a positive …
A Multi-omics Study of "Healthy" Premature CAD Patients
The goal of this multi-center observational clinical trial is to investigate the genetic risk factors of patients with premature CAD and none traditional CAD risk factors through a multi-omics approach. The main questions it aims to answer are: Genetic risk factors & metabolic fingerprints of patients with premature CAD and …
