Lp(a) With CCTA Assessed Parameters and Clinical Outcomes
Coronary Artery DiseaseLipoprotein(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.
Imaging and Physiologic Evaluation of Coronary Artery Disease
Ischemic Heart DiseaseAtherosclerosisTo 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.
CArdioMetabolism and Atherosclerotic PlaqUe progreSsion
Coronary Artery DiseaseDiabetes Mellitus4 moreSystematic 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.
Comparison of Troponin Assay With New POCT Method in the Decision-making Pathway of Patient With...
Chest PainMyocardial IschemiaThis is a prospective observational study aiming to evaluate the diagnostic accuracy of the high-sensitivity Troponin assay performed with the Atellica VTLi POCT system (by comparison with the results obtained with the Atellica diagnostic system currently in use) and to evaluate the impact of the POCT system on the reduction of decision-making time (particularly of "rule-out"), by evaluating the number of cases in which the conclusion of the decision pathway at 3 h (algorithm currently in use) could have been concluded at 1 h.
Functional ComprEhensive AssessmenT by IVUS Reconstruction in Patients With Suspected IschEmic Heart...
Ischemic Heart DiseaseInvestigating 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.
Validation of vFFR as Compared to FFR to Guide Revascularization of Non-culprit Lesions in STEMI...
ST Elevation Myocardial InfarctionMultivessel Coronary Artery Disease1 moreThis 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.
REASSURE-NIRS Registry
Lipid-Rich Atherosclerosis of Coronary ArteryRESSURE-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.
Functional Assessment by Virtual Online Reconstruction. The FAVOR III Europe Japan Study
Coronary Artery DiseaseQuantitative Flow Ratio (QFR) is a novel method for evaluating the functional significance of coronary stenosis. QFR is estimated based on two angiographic projections. Studies have shown a good correlation with the present wire-based standard approach Fractional Flow Reserve (FFR) for assessment of intermediate coronary stenosis. The purpose of the FAVOR III Europe Japan study is to investigate if a QFR-based diagnostic strategy will results in non-inferior clinical outcome after 12 months compared to a standard pressure-wire guided strategy in evaluation of patients with chest pain (stable angina pectoris) and intermediate coronary stenosis.
Impact of IntraVascular UltraSound Guidance on the Outcomes of Xience Prime Stents in Long Lesions...
Myocardial Ischemia(Implanted Drug-eluting Stents Because of Ischemic Heart Disease(Stable AnginaAcute Coronary Syndrome))The investigator aimed to evaluate the long-term (up to 10 years) follow-up of the patients who enrolled the IVUS-XPL study (Impact of IntraVascular UltraSound Guidance on the Outcomes of Xience Prime Stents in Long Lesions), which was shown the superiority of IVUS-guided stent implantation at 1 year in terms of major adverse cardiac events.
