Active clinical trials for "Myocardial Infarction"

The overall aim and primary objective is to evaluate the effects on level of depression and anxiety of an Internet-based CBT-program in depressed and/or anxious patients after a myocardial infarction (MI).

The aim of the study is to demonstrate the safety and efficacy of the TCD-10023 (Ultimaster) sirolimus eluting stent in patients with acute ST-elevation myocardial infarction (STEMI), by proving superiority with respect to in-stent late loss at 6 months to the Kaname bare metal stent and non-inferiority with respect to Target Vessel Failure (TVF) at 12 months.

This study is aiming to test the hypothesis that efficacy of rhTNK-tPA was not inferior to rt-PA with respect to the 30-day MACCE rates after fibrinolytic therapy for STEMI patients. It is a multicenter, randomized, open, parallel, active-controlled, non-inferiority trial.

Taken together the results from CHARISMA and PEGASUS-TIMI54, it appears that physicians may consider extending beyond 1 year or reinitiating treatment with clopidogrel 75 mg od or ticagrelor 60mg bid in patients with a prior MI and features of high ischemic and low bleeding risk. Comparative clinical or pharmacodynamic studies, however, between clopidogrel 75 mg od and ticagrelor 60 mg bid in the chronic phase of stable post MI patients have not been performed. In a platelet substudy of PEGASUS-TIMI 54, 180 patients who had received >4 weeks of study medication had platelet reactivity assessment. Ticagrelor 60mg bid achieved high levels of peak and trough platelet inhibition in nearly all patients, with similar consistency of effect compared to 90mg bid. Platelet reactivity (PRU) was significantly reduced with ticagrelor 60mg bid compared to placebo. In light of this, we believe that a dedicated pharmacodynamic study of ticagrelor 60 bid mg vs clopidogrel 75 mg od in a PEGASUS-like population would be informative for the practicing clinician, thus setting the rationale for conducting this specifically designed investigation. This is a prospective, randomized, single blind, single center, crossover study. Eligible patients undergoing P2Y12 receptor antagonist therapy before screening will undergo a 14-day minimum washout period before randomization. Following screening/washout period (visit 1), patients will be randomized (visit 2, time 0) in 1:1 fashion to either clopidogrel 75 mg od or ticagrelor 60 mg bid. Following 14±2 days (visit 3) patients will receive alternate treatment for additional 14 days (visit 4). Platelet reactivity assessment will be performed with the VerifyNow P2Y12 reaction assay at time 0, prior to first study drug dose. At visit 3 platelet function will be assessed at 2-4 hours post dose and prior to crossover. At visit 4 also platelet function will be assessed at 2-4 hours post study drug post dose. All patients will receive concomitant aspirin (100 mg/d) and standard secondary prevention medication. The primary endpoint is the platelet reactivity measured in P2Y12 reaction units (PRU) at the end of the 2 study periods (pre-crossover and post-crossover).

The primary objective of the study is to collect confirmatory data supporting the safety and effectiveness of SSO2 Therapy in treatment of anterior acute myocardial infarction (AMI) patients who have undergone successful percutaneous coronary intervention (PCI) with stenting within six hours of experiencing AMI symptoms.

The main goal of this study is to evaluate the ability of a single administration of tocilizumab to reduce myocardial damage in patients presenting with an acute ST-segment elevation myocardial infarction (STEMI). Secondary objectives are to assess the impact of treatment on: (i) final infarct size, (ii) left ventricular size and function, (iii) inflammation, (iv) extracellular matrix remodeling, (v) lipid parameters, (vi) platelet activation and additional pro- and anti-thrombotic parameters, and (vii) study drug safety and tolerability.

This is a phase 1 multicenter, randomized, double-blind, placebo-controlled, ascending dose study to investigate the pharmacokinetics (PK), safety, and tolerability of CSL112 in adult subjects with moderate renal impairment and in healthy adult subjects with normal renal function.

The OxAMI-PICSO is a study about the use of pressure controlled intermittent coronary sinus occlusion (PICSO) to improve the treatment of patients presenting with heart attack. PICSO is a device consisting of a balloon which is deployed in the coronary sinus. When inflated the balloon can improve the blood flow to the region of heart affected by the heart attack. The study aims to analyse the potential benefit of PICSO in improving blood flow to heart muscle in a selected group of patients admitted with a large heart attack involving the anterior wall of the heart. The comparator group will be a well-matched group of participants of the ongoing OxAMI study. In order to select patients with a large heart attack, we will measure the index of microcirculatory resistance (IMR), before completion of the heart attack treatment procedure. The IMR value provides measurement of the blood flow at the level of the tiny vessels branching from the large coronary arteries. Our preliminary data from the OxAMI study have shown that an IMR > 40 suggests that the patient is having a large myocardial infarction (heart attack). Only patients with starting IMR > 40 will be considered eligible for the PICSO treatment. The benefit of PICSO will be assessed by measuring 1) indexes of coronary blood flow, 2) the extension of the infarcted area and 3) the levels of different molecules released in the blood.

This safety pilot study evaluates the effect of hydroxychloroquine on preventing recurrent cardiovascular events among myocardial infarction patients. Half of the participants will receive hydroxychloroquine, whereas the other half will receive placebo during six months.

Hypothermia may reduce infarct size in patients with acute myocardial infarction if provided before reperfusion. Human studies using systemic cooling methods failed to show a reduction in infarction size. The use of selective intracoronary hypothermia may overcome the problems of systemic cooling. The hypothesis of this study is that in patients with acute myocardial infarction, the induction of intracoronary hypothermia is safe and feasible.
