Active clinical trials for "Coronary Artery Disease"

The use of intra coronary physiological assessment with fractional flow reserve (FFR) is nowadays the standard approach to define ischemia-inducing stenosis and guide myocardial revascularization strategy in patients with coronary artery disease. Further, FFR has been shown to be a strong and independent predictor of major adverse cardiac events after stent implantation. A lower value of FFR after stent implantation is associated with a worse clinical prognosis, without a clearly defined threshold above which clinical follow up are similar for all FFR values. Among 750 patients in the Fractional Flow Reserve Post-Stent Registry, the event rate was 29.5% in patients with FFR<0.80 compared to 9 4.9% in patients with FFR>0.95 (p<0.001). However, FFR remains poorly adopted in many cathlabs, partly because of procedural time, discomfort or sides effect during hyperemia, non-uniform adenosine response and economical constraints. This leads to the validation of resting indices (instantaneous wave-free ratio (iFR), diastolic pressure ratio (dPR), and resting full-cycle ratio (RFR) among others). Those indices evaluate coronary physiology without the use of maximal hyperemia and have 15 slightly different threshold compared to FFR (≤0.89 vs 0.80, for iFR and RFR, and FFR 16 respectively).In the VALIDATE RFR study, a head-to-head comparison of RFR and iFR from a retrospective analysis, diagnostic accuracy of RFR was 97.4% with an area under the curve 1 (AUC) of 99.6%. In the more recent RE-VALIDATE RFR study, 431 patients with 501 lesions 2 were prospectively evaluated for the diagnostic performance of RFR in all-comers patients. Compared to iFR, RFR achieved high diagnostic accuracy, sensitivity and specificity. These are the reasons why we designed a prospective, non-randomized, clinical trial, to better 18 explore the value of RFR before and after PCI in real live and after optimization by post dilation 19 in all-comers patients with coronary artery disease in the Middle East region..

The Gladius First trial is designed as a single-centre, open, prospective, randomized clinical trial aimed to assess the efficiency and safety of coronary chronic total occlusion (CTO) percutaneous coronary intervention (PCI) using the antegrade wiring strategy with a first-choice intermediate Gladius guidewire. To this end, consecutive patients referred to CTO PCI with intended primary antegrade wire escalation strategy, will be randomized in a 1:1 fashion to antegrade wiring starting with the Gladius guidewire or antegrade wiring using the standard guidewire escalation strategy.

In this prospective open-label randomized tral, 100 patients with elective off-pump coronary artery bypass (OPCAB) or minimal invasive direct coronary bypass (MIDCAB) surgery were enrolled. Before surgery, if a patient had iron deficiency anemia, the patient was randomized to receive Ferinject®(Ferric carboxymaltose, n=50) or placebo (normal saline, n=50), respectively. A single dose should not exceed 1000mg of iron per day or 20mg per kg body weight. In addition, the administration of 1000mg of iron should not exceed once a week. Administration to patients with hemodialysis-dependent chronic kidney disease is once daily, and the maximum dose should not exceed 200 mg (4 ml) of iron. Patients weighing less than 35 kg should not exceed 500 mg total iron dose. It uses intravenous infusion and can be administered up to 1,000mg (20ml) as the maximum iron once. For intravenous infusion, this drug is diluted with 0.9% sterile physiological saline solution.

The study is to evaluate the effect of optimized 12-month step-down antiplatelet therapy (APT) compared with standard 12-month dual antiplatelet therapy in clinical net adverse events, cardiovascular and cerebrovascular adverse events and reducing clinical related bleeding events in the patients with acute coronary syndrome (ACS) who are not the predominant coronary artery disease after percutaneous coronary intervention (PCI).

The aim of this prospective randomized study was to assess the efficacy of ablation of the ganglionated plexi localized in the epicardial fat pads for preventing recurrences of atrial tachyarrhythmia in patients with paroxysmal atrial fibrillation undergoing coronary artery bypass grafting.

LEADERS-FREE trial demonstrated the safety and efficacy of polymer-free drug-coated stent (Biofreedom, Biosensors International Technologies, Singapore) in patients with high bleeding risk. But, there are limited clinical evidences for extending these findings to generalized patients who are eligible to PCI. Therefore, the purpose of this registry is to evaluate the safety and efficacy of Biofreedom stent in patients with coronary artery disease.

In this study, typical cases of coronary heart disease are selected. They will be intervened by Xuesaitong soft capsules to investigate efficacy and safety for Coronary Heart disease.

evaluate the safety of preoperative aspirin therapy when performing bypass surgery in conditions of artificial blood circulation

The purpose of this study is to evaluate the safety and performance of a new version of a coronary artery stent for treating blockages in the arteries supplying blood to the heart muscle. The Amaranth Medical MAGNITUDE scaffold releases a drug (sirolimus) to reduce the likelihood of the treated blood vessel developing a new blockage. In addition, the scaffold dissolves away over time, leaving no permanent implant after the blood vessel has healed.

Arterial access is the key step during the endovascular treatment of cardiovascular diseases. This study was designed to confirm the safety and efficacy of the hemostasis pad using chitosan in patients undergoing percutaneous procedures with arterial approach. Two cohorts will be included in this study: transradial and transfemoral cohort. Among the transfemoral cohort, the safety and efficacy of the ezClot pad will be compared with the BloodSTOP® pad (LifeScience PLUS, Palo Alto, CA, USA). The BloodSTOP® pad is an etherized and oxidized regenerated cellulose matrix that achieves hemostasis by activating the intrinsic coagulation pathway. The hypothesis will be tested among the transradial cohort that the combined use of a hemostasis pad and a compression device is superior to that of a compression device only in terms of hemostasis in patients who underwent tranradial coronary procedures.
