Active clinical trials for "Myocardial Infarction"

The purpose of this study is to demonstrate the feasibility of pacing as a therapy to prevent adverse remodeling of the myocardium following an acute myocardial infarction (MI) in patients at highest risk for adverse myocardial remodeling.

The aim of the FOCUS project is to test the Fixed Dose Combination concept for cardiovascular prevention in populations of different socio-economic characteristics. At the same time, FOCUS aims to understand the factors determining inappropriate prescribing for secondary cardiovascular prevention and those for poor patients adherence to treatment. This will allow FOCUS to establish recommendations for a better use of medication in patients with ischemic heart disease. In addition, after a successful completion of FOCUS, secondary prevention medication will be available and affordable for a large number of patients in both developed as well as developing countries. There are two Phases in this study: Phase 1: Is a descriptive, non interventional study. Phase 2: Is an interventional, randomized trial with prospective economic evaluation.

The purpose of the study is to examine the effect of the cholesterol lowering agent Ezetimibe when used in addition to optimal treatment with Atorvastatin in patients with acute ST-Elevation Myocardial Infarction (STEMI) who have not been in prior statin therapy. An area with arteriosclerosis not demanding intervention in a coronary vessel other than the infarct related is used as measuring point and is examined at time of the infarction and after 12 month using intravascular ultrasound and optical coherence tomography. At the same time the same techniques are used to examine the implanted stent.

The purpose of this study is to determine whether the intravenous administration of single- and multiple-ascending doses of Thymosin Beta 4 is safe and tolerable in healthy volunteers.

The purpose of this study is to compare the effects of the consumption of two different dietary patterns (low fat versus Mediterranean Diet) on the incidence of cardiovascular events of persons with coronary disease.

Primary objective: To evaluate whether 12 weeks of clopidogrel is superior to ticlopidine in terms of lower risk of the safety events of interest in patients with stable angina (SA) or old myocardial infarction (OMI) to which percutaneous coronary intervention (PCI) is being planned. Secondary objectives: To compare the incidence of adverse events, adverse drug reactions and bleeding events in patients treated with clopidogrel versus ticlopidine. To compare the incidence of major adverse cardiac events (MACE) and major adverse cardiac and cerebrovascular events (MACCE) in patients treated with clopidogrel versus ticlopidine. To evaluate the long-term safety (adverse drug reactions, adverse events, safety events of interest and bleeding events) of clopidogrel for a total of 52 weeks; To evaluate MACE and MACCE of clopidogrel for a total of 52 weeks.

This study will examine the safety and effectiveness of a manganese-based agent called SeeMore (EVP 1001-1 Injection) for enhancing magnetic resonance imaging (MRI) in patients who have previously had a heart attack. It will determine whether SeeMore makes it easier to find damaged areas of the heart and will evaluate how well patients feel and how their bodies react after receiving the study medication. Adult patients who have previously had a heart attack and are in stable health may be eligible for this study. Candidates are screened with a medical history, a brief physical examination and blood and urine tests. Participants undergo the following procedures: Collection of blood and urine samples 24 hours before receiving SeeMore and 24 hours after. A blood sample is also taken 3 and 10 days after receiving the drug. MRI scans one hour before receiving SeeMore and 10 minutes after receiving the drug. MRI uses a magnetic field and radio waves to produce images of body tissues and organs. After the first (baseline) MRI is done, SeeMore is given intravenously (through a vein) and the subject's vital signs and electrocardiogram (EKG) are monitored for 10 minutes. Then the second MRI is done to determine whether the study medication makes it easier to see areas of the heart that were affected by the heart attack. Check of vital signs, EKG and physical examination after the second MRI.

During acute coronary syndromes (ACS), the generation of inflammatory mediators negatively influences arterial wall remodeling and the endothelium-dependent vasomotor function in the coronary and systemic arterial systems. In fact, the intensity of the inflammatory upregulation is strongly related to the incidence of recurrent coronary events. The investigators previously demonstrated that high dose potent statins can rapidly reduce plasma levels of cholesterol-rich lipoproteins and inflammatory activity in subjects during ACS. In addition, such statin treatment attenuates the post-discharge endothelial dysfunction of these patients. By inference, it is plausible to hypothesize that these beneficial effects during ACS may be intensified by an additive lowering of plasma cholesterol through the treatment with ezetimibe. So far, data is unavailable to verify this assumption. In parallel, data from animal models have suggested that both statins and ezetimibe may reduce insulin sensitivity by their effect on cholesterol content and, by this way, on insulin signaling in liver cells. In this context, the present study aims to investigate the role of the addition of ezetimibe upon statin treatment on stress-induced insulin resistance and on the time-course of the inflammatory response during the acute phase of myocardial infarction and its late effect on endothelium-dependent arterial dilation.

The goal of this clinical research study is to compare the effects of sodium bicarbonate to normal saline when used for clearing mucus blockage in patients with airway stents.

The purpose of this project is to examine the effectiveness of computed tomographic angiography (CTA) in patients with non-ST elevation acute coronary syndrome (NSTE-ACS). People who are hospitalized with this situation often require an angiogram to assess the heart and its arteries. Recent advancements in technology have enabled CTA to clearly define coronary artery anatomy with great accuracy and to guide treatment strategies in select patient populations. We are investigating that CTA may be used, as an alternative to conventional angiograms, for the risk stratification of patients with high risk NSTE-ACS. Patients eligible for the study will be high risk NSTE-ACS and awaiting an angiogram. Enrolled patients will undergo CTA prior to the angiogram. With each CTA the patient will be injected with a small dose of an X-ray dye and will be asked to lie still on the "scanning bed" for a period of 5-10 minutes.
