Active clinical trials for "Myocardial Infarction"

To compare the effect of a single high dose of atorvastatin versus rosuvastatin preloading on microvascular coronary perfusion as determined by CTFC in patients with ST-segment elevation myocardial infarction (STEMI) undergoing PCI.

Different types of statins show different influences on glycometabolism. There are no systemic analyses of the effects that statins exert on the metabolism of glucoses so far in China. This research aims to compare impacts on the glycometabolism of pitavastatin in AMI patients with atorvastatin and to accumulate data for guiding the utilization of statins.

This is a Phase 3 prospective, blinded, randomized, placebo controlled, international multicenter study. Subjects with STEMI will be enrolled in the ambulance if they meet all eligibility criteria. These subjects will be evaluated by (para)medics who transport the subjects to the participating hospitals in Europe and North America. Hospitals and ambulance services with experience in ambulance studies will be selected. Each subject will receive a single subcutaneous injection containing either zalunfiban Dose 1 (0.110 mg/kg) or zalunfiban Dose 2 (0.130 mg/kg) or placebo

Dapagliflozin is one of the SGLT-2 inhibiters. Recent clinical trials have demonstrated that SGLT-2 inhibitors are effective for treating heart failure. The DAPA-HF clinical trial has demonstrated that the effects of empagliflozin and dapagliflozin improve renal outcomes and reduce all-cause and cardiovascular death in patients with HFrEF[1]. However, its effect on myocardial infarction, the most common disease leading to death in the population, has not been evaluated sufficiently. A meta-analysis has demonstrated that compared with the control, SGLT2 inhibitor is associated with a reduction in the incidence of major adverse cardiovascular events (MACEs), myocardial infarction, cardiovascular mortality and all-cause mortality[2]. It seems that dapagliflozin might be effective for patients with acute myocardial infarction based on these studies. Thus, this study aims to evaluate the effect of dapagliflozin on short-term prognosis in patients with acute myocardial infarction compared to placebo.

Left ventricular thrombus is a common complication subsequent to ST-segment elevation myocardial infarction (STEMI) that related to increased embolic events. This study aims to assess the efficacy and safety outcomes of Rivaroxaban on the treatment of post-STEMI left ventricular thrombus.

REBOOT clinical trial will study whether long-term maintenance beta-blockers therapy results in a clinical benefit after heart attack without reduced left ventricular function. Half of the participants will be randomized to receive long-term beta-blocker therapy and the other half to no beta-blocker therapy after hospital discharge. All patients will be followed up for up to 3 years to determine the occurrence of adverse events (all cause mortality, re-infarction, and heart failure admission).

In a prospective, randomized clinical trial the iPOST2 trial will determine whether ischemic postconditioning reduces reperfusion injury and this will translate into improved clinical outcome of heart failure and death for STEMI patients who present with TIMI0-1 undergoing primary PCI

Trial Name) Impact of Immediate SteNt ImplaNtatiOn Versus Deferred Stent ImplAntaTION on Clinical Outcomes in Patients with AnteRior Wall ST-segment Elevation Myocardial Infarction (INNOVATION-CORE) Objectives) To evaluate the impact of deferred versus immediate stenting in patients with acute ST-segment elevation anterior wall myocardial infarction (STEMI) on the clinical efficacy and safety the microvascular obstruction using Cardiac magnetic resonance (MR) the structural and functional cardiac remodeling using conventional echocardiography and strain imaging the intravascular findings using optical coherence tomography (OCT) Study Design) A multicenter, prospective, randomized, controlled, open-label clinical trial for anterior wall STEMI patients Patient Enrollment) 460 patients will be enrolled at 20 centers in South-Korea Patient Follow-Up) Clinical follow-up will occur at 1, 6, 12 months, 2, 3 years and 5 years.

The investigators hypothesize that preventive VT substrate ablation in patients with chronic ICM, previously selected based on imaging criteria (BZC mass) for their likely high arrhythmic risk, is safe and effective in preventing clinical VT events.

This study will assess the safety and feasibility of sonothrombolysis in the acute management of STEMI undergoing reperfusion therapy with systemic fibrinolysis as part of a pharmacoinvasive approach
