Active clinical trials for "Coronary Artery Disease"

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.

To evaluate the safety and efficacy of MiStent drug (sirolimus)-eluting stent system in the treatment of coronary heart disease (CHD) in patients with primary in situ CHD (de novo); To evaluate operating performance of the MiStent drug (sirolimus)-eluting coronary stent system.

Prolonging infusions may decrease myocardial damage associated with bivalirudin use during primary PCI. The investigators hypothesized that continuing the bivalirudin infusion commenced during the procedure at the PCI recommended dose for 4 hours would prevent myocardial damage.

Patients with stable coronary disease when undergoing percutaneous coronary intervention may present periprocedural myocardial infarction defined at present as a creatine kinase-myocardial isoenzyme (CK-MB) elevation 3 times upper limit of normal, as a cut off for periprocedural myocardial infarction after PCI. Although percutaneous coronary intervention is associated with low rates of complications, periprocedural myocardial infarction has been touted as a negative factor in long-term clinical results . Several clinical, anatomical and technical associate to the occurrence of this event . Although randomized controlled trials and systematic reviews to statin pre intervention have targeted the administration of high-dose statin is recommended before surgery to reduce the risk of periprocedural myocardial infarction, there is no information on the impact of the maximum concentration plasma of statin at the time of percutaneous coronary intervention in stable patients on chronic statin use in preventing periprocedural myocardial infarction or the elevation of cardiac enzymes . The anti-ischemic effect of statins in percutaneous coronary intervention was mainly determined in statin -naïve patients or in patients with acute coronary syndromes . In this work , we studied the impact of the peak plasma concentration of statin at the time of percutaneous coronary intervention was studied through prospective randomized single center in stable patients with chronic statin divided into two groups . In the group (1) Experimental (n = 268 ) was administered at a dose of 40 mg rosuvastatin between one and six hours before surgery and group (2) control without rosuvastatin (n = 268). This range 1 to 6 hours is the time at the peak concentration of rosuvastatin in the blood after oral ingestion. The primary objective was to assess the incidence of periprocedural myocardial infarction by creatine kinase above three times upper normal limit in hospital period and as a secondary objective to analyze the elevation of any amount of creatine kinase on the baseline.

The NeoVas First-in-Man study is a prospective, two centers, single arm trial, which will enroll a total of 30 patients. The hypothesis of this study is to evaluate clinical feasibility, safety, and efficacy of NeoVas sirolimus-eluting bioresorbable coronary scaffold in the treatment of patients with de novo coronary lesion.

meriT-V is a Prospective,active control open lable clinical trial to compare safety & efficacy of BioMime Sirolimus stent Vs. Xience family of Everolimus stent by random assignment for treatment of coronary artery disease at multiple multinational centres.

The aim of this study is to determine the effects of omega 3 supplementation and its concurrent supplementation with vitamin E on the serum levels of antioxidant enzymes and the expressions of the PGC-1a, h TERT, FOXO1, FOXO3a , SIRT1,SIRT3, SIRT6 genes in PBMC cells in the patients with coronary artery disease

Study objectives To compare the safety and long-term efficacy of coronary stenting with biostable polymer drug-eluting stent (Promus PremierTM, Xience Alpine®, Resolute Onyx®) with biodegradable polymer drug-eluting stent (Biomatrix®, Biomatrix Flex®, Nobori®, Ultimaster®, Synergy ® and Orsiro®) in patients with acute coronary syndrome To compare the efficacy and safety of 5 mg prasugrel maintenance therapy compared with 10 mg prasugrel maintenance therapy in patients with acute coronary syndrome undergoing percutaneous coronary intervention Study design : Prospective, open-label, 2-by-2 multifactorial, randomized, multicenter trial to test the following in CHD patients Non-inferiority of biostable polymer drug-eluting stent (Promus PremierTM, Xience Alpine®, Resolute Onyx®) compared with biodegradable polymer drug-eluting stent (Biomatrix®, Biomatrix Flex®, Nobori®, Ultimaster®, Synergy ® and Orsiro®) in terms of patient-oriented composite outcome Non-inferiority of 5 mg compared to 10 mg dose of prasugrel maintenance in terms of major adverse cardiovascular events

The purpose of this study is to evaluate effectiveness and safety of DESyne in Routine Clinical Practice

Statin interference has been suggested among the mechanisms of reduction of the antiplatelet effect of clopidogrel. The purpose of this study is to evaluate pharmacodynamic effects of rosuvastatin and atorvastatin on platelet reactivity in patients with coronary artery disease undergone double antiplatelet therapy with new P2Y12 inhibitors. This is a single-center, prospective, randomized, crossover study conducted in the Department of Heart and Great Vessels "Attilio Reale", Sapienza University, Rome, Italy. All consecutive patients undergone PTCA in our institution in the period between July 2013 and December 2013 will be eligible to be enrolled. Patients will be offered to participate to the trial at time of 1-month post-angioplasty follow-up visit.patients receiving dual antiplatelet therapy (prasugrel 10 mg or brilique 90 mg x 2 plus aspirin 100 mg) after percutaneous coronary intervention. Patients were randomly assigned to rosuvastatin (20 mg day) or atorvastatin (40 mg day) for 30 days. After 1-week wash-out period to avoid any carryover effect, cross-over was performed, and patients were switched to the other drug which was continued for 30 days. Platelet function will be evaluated using a validated method: the VerifyNow System (Accumetrics Inc., San Diego, CA), which is a point-of-care turbidimetry-based optical detection system that measures platelet-induced aggregation. Platelet function will be measured with the VerifyNow P2Y12 test at baseline and after 30 days from rosuvastatin or atorvastatin administration. Platelet reactivity will be expressed in P2Y12 reaction units (PRU). PRU values >208 are suggestive of high platelet reactivity.
