Active clinical trials for "ST Elevation Myocardial Infarction"

Study objective is the evaluation of safety and efficacy at 9 months of combination treatment of bare metal Stent plus Paclitaxel Eluting Balloon vs bare metal stent (conventional treatment) in patients with acute myocardial infarction with systolic time elevation of less than 12 hours of evolution.

A Phase IIb clinical trial to investigate the safety and efficacy of antiplatelet thrombolysin injection for patients with ST Segment Elevation Myocardial Infarction (STEMI) before receiving PCI therapy, in order to provide evidence for Phase III design.

This randomized, controlled trial compares the anti-thrombotic effect of cangrelor and ticagrelor on platelet activity in patients with acute ST-elevation myocardial infarction. Patients will receive either prehospital ticagrelor (180 mg - crushed) or in-hospital cangrelor (bolus 30 μg/kg within 1 minute followed by infusion (4 μg/kg/minute) for two hours) followed by 180 mg ticagrelor. The primary study end-point is platelet reactivity at sheath insertion, at the end of the PCI procedure (before sheath removal) and two hours after PCI is initiated. The secondary end-point is the proportion of patients with inappropriate or harmful P2Y12 administration.

The disease under study is acute coronary syndrome with ST segment elevation, defined as patients presenting chest pain of anginal characteristics of more than 20 minutes of duration, with changes in the electrocardiogram consisting of ST segment elevation of 1 mm in two contiguous limb leads or 2 mm in two contiguous leads precordial. In a review carried out on patients treated in the investigator center with SCACEST, invetsigators found that, in a cohort of 250 patients, 85% of them presented alterations Segments of left ventricular contractility at 4 months after the acute episode. To verify that the Levosimendan administration reduces that percentage, at least 65%, investigators require to include in the study 83 patients in the experimental group and 83 in the control group, for a power of 80% and a confidence level of 95%. Assuming 10% of lost patients, it is required to include in the study 92 patients in the experimental group and 92 patients in the group control .

The study will assess the safety and performance of the Fantom sirolimus eluting bioresorbable vascular scaffold (BVS) in the acute setting of myocardial infarction with unstable lesions and thrombogenic milieu.This is a prospective evaluation of clinical and patient related measures in STEMI patient who undergo urgent primary percutaneous coronary intervention (PCI) with stent implantation. Patients with culprit lesions with 2.5 - 3.5 mm diameter and located in one of the main coronary arteries will be included in the trial and prospectively observed. The study will comprise 20 patients, who will undergo additional evaluation with optical coherence tomography (OCT) and near-infrared spectroscopy/intravascular ultrasound (NIRS/IVUS) at baseline, 6 months, 18-24 months and 36 months. The device will be delivered in sizes 2.5 and 3.0 in diameter / 18 and 24 mm and 3.5 mm x 18 mm in length.

To explore the protective effect of prostaglandin sodium on coronary microcirculation function and ventricular remodeling after reperfusion treatment of acute ST-segment elevation myocardial infarction.

Ticagrelor inhibits inflammation and improves vascular endothelial cell function to a greater extent than clopidogrel in ST-segment elevation myocardial infarction(STEMI) patients receiving percutaneous coronary intervention. Ticagrelor can reduce the serum levels of inflammatory biomarkers both in coronary and in peripheral venous in patients with ST-segment elevation myocardial infarction(STEMI).

The aim of this randomized controlled trial to investigate the effects of CPAP treatment on myocardial salvage index and clinical outcomes at 3 months in patients with OSA and ST-Segment Elevation Myocardial Infarction (STEMI) after primary percutaneous coronary intervention (PPCI).

The study aims to evaluate whether an early intracoronary administration of Fasudil Hydrochloride during primary PCI of STEMI can improve epicardial and myocardial perfusion as well as clinical outcomes.

This is a single-centred, double blind randomized controlled trial comparing ticagrelor with placebo in clopidogrel and aspirin loaded patients.
