Active clinical trials for "Infarction"

Based on accumulating evidences showing that hypothyroid status is associated with poor prognosis among acute myocardial infarction (AMI) patients, the study is designed to evaluate whether replacement treatment with levothyroxine could have beneficial effects on patients with AMI and hypothyroidism. This is a multicenter prospective computerized-randomized trial stratified by ejection fraction with a 1:1 ratio to levothyroxine group or standard therapy group.

The study (Statin Eligibility Prior to myocardial infarction (MI) in Jordanians, StatinEPIC) is Cross sectional Non interventional One encounter per patient. No follow up. It addresses a major issue of primary prevention in Jordanians especially the young population, namely the issue of lipid lowering agents before sustaining an acute MI. A recent study in USA showed that 50% of patients who sustained MI were not eligible to statins had they been evaluated before the heart attack. It is largely unknown if a larger percentage of Middle Eastern patients who sustain a heart attack would be eligible to receive lipid lowering agents. The PI will overlook the whole process. Dr Ahmad Tamari, the assistant to the PI will asses this whole process of data collection, management and manuscript drafting.

The CIAKI,as the third complication of PCI, was associated with adverse cardiac events after procedure. Moreover, because the rate of periprocedure hydration is inadequate in STEMI patients before primary PCI, the incidence of CIAKI is higher significantly in these patients. The cardiovascular pleiotropic effects of statins in addition to lipid have been widely concerned. The previous studies demonstrated usage of statin in periprocedure could decrease the risk of CIAKI. Compared with hydration, the usage of statin to prevention CIAKI show the advantages in clinical practice, for example，there is no need to consider the cardiac function.The optimal strategies for preventting CIAKI in STEMI patients undergoing primary PCI needed further studies to explore. What's more, whether a synergistic effect of hydration and statin or not is unknown.

This is a prospective, randomized study with blinded outcome assessment, comparing routine manual thrombus aspiration with no aspiration in patients with acute ST-segment elevation myocardial infarction (STEMI) underwent percutaneous coronary intervention (PCI).

The patients with acute myocardial infarction (AMI) present high mortality and morbidity rate,even treated with stenting in the blocked heart vessels. The appearance of no-reflow is common after re-opening of the blocked vessel. The no-reflow were commonly attributed to tiny blockage in coronary micro-vasculature by thrombus and spasm of the micro-vessel during stenting. An agent with more effective anti-clotting and micro-vessel dilation would be helpful to solve the issue of no-reflow. Ticagrelor was demonstrated to be a potent platelet inhibitor and a potent micro-vessel dilator which can influence metabolism of adenosine, a endogenous potent small vessel dilator. This study is to test the effectiveness of ticagrelor on improving reperfusion and minimizing the myocardial infarct size after PPCI in patients with AMI.

Stroke is one of the three leading causes of human death, and a major cause of adult disability. Our pre-clinical studies confirmed that ischemic preconditioning can prevent cerebral infarction. Animal studies confirmed that ischemic postconditioning can reduce infarct size of cerebral infarction. Investigators hypothesized that postconditioning would reduce infarct volume of ischemic stroke patients.

This study aims to assess the effect of exenatide on myocardial injury in patients undergoing emergent percutaneous coronary intervention (PCI) for ST segment elevation myocardial infarction or heart attack (STEMI).

To study the effects of Erigeron Injection on human serum VEGF, MMP-9 and EPC levels after acute cerebral infarction,test is made by random double-blind controlled.patients with acute cerebral infarction were divided randomly into erigeron injection+aspirin group,aspirin group,and health people. The main indexes are the serum level of VEGF, MMP-9 and EPC.The review is made by the reference to NIHSS and so on. So, Erigeron Injection have the function of promoting angiogenesis in multiple targets through this test.

Introduction: In the setting of acute ST-segment elevation myocardial infarction (STEMI) coronary wedge pressure (CWP) emerges as a new marker for the advanced form of pre-procedural microvascular obstruction (MVO), which is associated with inflammatory interstitial edema. Through its anti-inflammatory effects, glucocorticoid therapy may prove beneficial in patients with high CWP. Aim: To identify the presence of the advanced form of MVO before primary percutaneous coronary intervention (PPCI) by CWP measurement and to test the benefit of cortisol therapy, in terms of infarct size and left ventricular remodeling, in patients with raised CWP. Methods: 50 patients with a first STEMI, candidates for PPCI, with proximal coronary occlusion, will undergo CWP measurement followed by percutaneous revascularization. Cardiac MRI will be performed 3-5 days after the procedure. A cutoff for CWP in predicting MVO, interstitial oedema and intramyocardial haemorrhage will be derived.Based on the above mentioned cutoff, 180 patients with continuous elevation of the pressure line will be randomized, by a 1:1 model, either to cortisol therapy or to placebo. Inflammatory parameters will be determined from peripheral blood samples. Patients will undergo cardiac magnetic resonance (CMR) imaging 3 to 5 days after revascularization. Study endpoints: The primary endpoint will be the extent of MVO, interstitial edema and hemorrhage. Secondary endpoints will include infarct size, myocardial salvage, left ventricular volumes and ejection fraction. The clinical endpoints of all-cause and cardiovascular death, myocardial re-infarction, target vessel revascularization, stent thrombosis and stroke will be recorded at 6 months.

This study aims to demonstrate that the BioFreedom™ Cobalt Chromium Drug Coated Stent is non-inferior to the market authorized BioFreedom™ Stainless Steel Stent with respective to efficacy and shows a similar safety profile.
