The Computed Tomography-derived Fractional Flow Reserve STAT Trial
Heart DiseaseCoronary2 moreThis study is designed to directly compare Standard Care and CT fractional flow reserve (CTFFR) for diagnosis of chest pain patients with definite coronary artery disease (CAD) on heart computed tomography (CT) scans.
Addiction and Acute Coronary Syndrome
Acute Coronary SyndromeAddictionthe study aims to identify the effect of addiction on TIMI flow in patients presented with acute coronary syndrome. identify the effect of addiction on outcomes of medical treatment of patients presenting with acute coronary syndrome. identify the relation between addiction and LV function. detect the effect of duration of addiction on myocardial infarction lesion and outcomes of pci.
Testing P2Y12 Platelet Inhibitors Generics Beyond Bioequivalence
Cardiovascular DiseasesAcute Coronary SyndromeThis is a pilot study that was conducted to prove the efficacy and safety of ticagrelor generically named Ticaloguard® compared to its brand Brilique® in healthy volunteers. we advocate comparing the clinical efficacy rather than simple bioequivalence comparison.
OPTImal CArdiac REhabilitation (OPTICARE) Following Acute Coronary Syndromes
Risk Reduction BehaviorLife StyleThe objective is to investigate whether in acute coronary syndrome patients the cardiac risk profile will improve with 2 new extended cardiac rehabilitation interventions and if these patients maintain healthier life style habits and a more active life style compared to patients randomized to standard cardiac rehabilitation.
Safety and Efficacy of Ticagrelor Versus Clopidogrel in Asian/KOREAn Patients With Acute Coronary...
Acute Coronary SyndromeMyocardial Ischemia3 moreThe purpose of this study is to assess safety and efficacy of Ticagrelor versus Clopidogrel in Asian/KOREAn patients with acute coronary syndromes intended for invasive management.
Post Acute Coronary Event Smoking Study
Smoking CessationAcute Coronary SyndromeSmoking and depressed mood are both predictive of mortality following Acute Coronary Syndrome. However, to date, no counseling treatment has been designed to target smoking cessation and manage mood in this population. This trial will test such a treatment based on Behavioral Activation, an approach that has shown promise as an integrated treatment for smoking and mood management in other populations.
Fixed-dose vs. Phenotype-based PrAsugrel Dose to MATCH Therapeutic Zone in Asians With Acute Coronary...
Acute Coronary SyndromePlatelet Thrombus1 moreThe purpose of this study is to determine whether the fixed-dose (prasugrel 10 mg/d vs. 5 mg/d) vs. phenotype (platlet function test by VerifyNow P2Y12 assay)-based prasugrel dose adjustment can match therapeutic zone of platelet reactivity in PCI-treated Asians with acute coronary syndrome
Transition From Ticagrelor to Clopidogrel Following Acute Coronary Syndrome: To Bolus or Not?
Acute Coronary SyndromeAfter a heart attack patients are routinely started on drugs to inhibit platelets. Ticagrelor is a powerful anti-platelet drug with clinical benefits. However it must be discontinued in some, because of increased risk of bleeding or intolerance. These patients need to be transitioned to another agent, such as Clopidogrel. At present, there is no clinical consensus on the optimal strategy for this switch. Some clinicians elect to give a bolus dose of clopidogrel with 600mg, while others start directly with a 75mg daily dose, with no evidence regarding the benefits or potential complications associated with each strategy. The present proposal will evaluate the pharmacodynamics of 2 strategies with specialized platelet function testing. We hypothesize that a bolus dose of clopidogrel during the switch will confer better ischemic protection without increasing bleeding risk for patients undergoing a switch in therapy.
Paradigm Shift in the Treatment of Patients With ACS
Acute Coronary SyndromeThis protocol describes a pilot study intended to test the hypothesis that patients with acute coronary syndrome (ACS) caused by plaque erosion can be stabilized by effective antithrombotic treatment without stent implantation, thereby avoiding both early and late complications related to percutaneous coronary intervention (PCI).
Effects and Plasma Concentration of Ticagrelor, After Crushed and Non-crushed Intake, After Acute...
Acute Coronary SyndromeThe first aim of the study is to prove that after starting the therapy with crushed tablets, the platelet inhibition will be as expected after starting therapy with intact tablets. Gurbel et al. showed that 100% of the patients on ticagrelor treatment have a decrease from baseline platelet aggregation of >10% 4 hours after last maintenance dose. So the investigators expect that after 3 days of treatment, all of our patients will have a closing time of more than 106seconds. The investigators will observe two different clinical conditions of Acute Coronary Syndrome. First after semi-urgent coronary artery bypass graft (CABG) surgery, secondly in patients after cardiac arrest. Both are clinical situations in which crushed tablets are needed to give. The second objective is to determine plasma concentrations of Ticagrelor and AR-C124910XX (active metabolite of ticagrelor) in these two patient populations after receiving 180mg or 90mg start-dose. Determination of plasma concentrations is done after protein precipitation, by using liquid chromatography with mass spectrometry detection. Measurements will be determined before intake (0h) and at 0,5; 1; 2; 4; 8; 24h and at day 4 +4h.7 The first 24h this will be a crushed tablet and 4 hours after the first intake at day 4 of therapy, this will be a non crushed tablet.
