Filter by:The activated clotting time (ACT), global thrombosis test (GTT-3), platelet inhibition P2Y12 (VerifyNow) test and serum coagulation factors will be measured in patients undergoing coronary angiography (CA) and percutaneous coronary intervention (PCI).
Due to differences in the mechanism of action, intravascular lithotripsy is likely to cause less distal embolization and microcirculatory dysfunction during plaque preparation. This may also translate into lower periprocedural myocardial infarction rates. Thus, this exploratory study aims to evaluate the microcirculatory function after the use of Shockwave® intravascular lithotripsy.
The purpose of this study is to determine the predictive capacity of the Pullback Pressure Gradient (PPG) index for post-PCI FFR and to determine the impact of the PPG index on clinical decision making about revascularization and on clinical outcomes.
Despite the fact that the topic of air pollution has been in focus of researchers for many years, there are no big studies that take up the matter of its influence on acute coronary, cerebral syndromes and CVD mortality in Europe. Taking into consideration the scarce number of surveys from Europe the investigators decided to analyze the impact of air pollution on cardiovascular diseases and CVD mortality in Poland.
In a prospective international multicenter observational study, 1080 stable chest pain patients (REALITY Advanced registry of CCTA patients) with the suspected chronic coronary syndrome will be enrolled. All of them will undergo computed tomography angiography, CMR and/ or SPECT, and Echo. One of the cohorts will be examined with multimodality invasive imaging including quantitative coronary angiography, FFR, QFR with or without further percutaneous coronary intervention, OCT, and some of them - with IVUS, VH-IVUS. The plaque size and relevant stenosis, a composition of the atherosclerotic lesion, major adverse cardiovascular events (all-cause death, death from cardiac causes, myocardial infarction, or rehospitalization due to unstable or progressive angina, ischemia-driven revascularization) will be judged to be related to either originally treated (culprit) lesions or untreated (non-culprit) lesions. Moreover, the clinical potential of both non-invasive and invasive imaging, as well as anatomical vs functional modalities in two real-world patient flows, will be estimated with the special focus on the natural progression of atherosclerosis, clinical outcomes, and safety (contrast-induced nephropathy, radiocontrast-induced thyroid dysfunction, and radiation dose). The diagnostic accuracy will be analyzed. The follow-up period will achieve 12 months prospectively with collected clinical events and imaging outcomes which will be determined at the baseline and 12-month follow-up. The independent ethics expertise will be provided by the Ural State Medical University (Yekaterinburg, Russia) and Central Clinical Hospital of the Russian Academy of Sciences (Moscow, Russia). The monitoring of the clinical data with imaging as well as further CoreLab expertise (expert-level post-processing multimodal imaging software of Medis Imaging B.V., Leiden, The Netherlands) will be provided by De Haar Research Task Force, Amsterdam-Rotterdam, the Netherlands. FFR-CT is scheduled to be assessed by the ElucidVivo Research Edition software from Elucid Bio, Boston, MA, U.S.A. The REALITY project is a part of the JHWH (Jahweh) International Advanced Cardiovascular Imaging Consortium. The main objective of the Consortium that is uniting international efforts of both Academia and Industry is a synergistic development of the advanced machine-learning imaging software in order to integrate benefits of both non-invasive and invasive imaging providing the daily clinical practice with the robust tool for the anatomical and functional examination of coronary atherosclerosis, PCI-related arterial remodeling, and relevant myocardial function.
