Active clinical trials for "Myocardial Infarction"

Trial design: This Phase III, investigator-driven, randomised, placebo-controlled efficacy and safety study will compare the effects of Sitagliptin in combination with granulocyte-colony stimulating factor (Lenograstim, G-CSF) on the improvement of myocardial function in patients undergoing routine percutaneous coronary revascularisation for acute myocardial infarction (time from onset of infarction to intervention 2 to 24 hours). The primary objective of this study is to compare between a treatment of G-CSF plus Sitagliptin, (G-CSF/Sitagliptin treatment group, n=87) versus Placebo (control treatment group, n=87) in change of global myocardial function from baseline to 6 months of follow-up.

Doctors use magnetic resonance imaging (MRI) to obtain detailed pictures of the inside of the body. This study will evaluate a new MRI technique in people who have recently had a heart attack. Researchers will also examine the effect of fish oil supplementation on heart health in study participants.

This trial was performed to evaluate the safety of G-CSF based stem cell therapy and to compare outcome of intracoronary infusion of mobilized PBSCs between patients with AMI and OMI.

The investigators hypothesized that complementary intracoronary streptokinase administration to primary percutaneous intervention in patients with acute myocardial infarction may provide further improvement in myocardial perfusion by dissolving microvascular thrombus [in situ formed or embolized from proximal site (spontaneous or following PCI)] and fibrin.

Following a Heart attack the acute loss of heart muscle cells results in a cascade of events causing an immediate decrease in cardiac function that has the potential to persist long term. Despite revascularization of the infarct related artery circulation and appropriate medical management to minimize the stresses on the heart walls, a significant percentage of patients experience permanent cardiac dysfunction and consequently remain at an increased life-time risk of experiencing adverse cardiac events, including death. There is a great potential for stem cell therapy, using a variety of cell precursors (particularly hematopoietic,)to contribute to new blood vessel formation (and possibly limited heart muscle formation) and muscle preservation in the myocardial infarct zone. The administration of cells via an infusion through the infarct related artery appears to be feasible and result in a clinical effect in some studies. Therefore, we propose to evaluate the safety and efficacy of a CD34+ selected stem cell product (AMR-001), administered through the infarct related coronary artery 6 to 9 days after successful infarct related artery stent placement. The primary objective of the study is to determine the feasibility and safety of prospectively identifying patients at risk for clinically significant cardiac dysfunction following a myocardial infarction and the ability to isolate and infuse via the affected coronary circulation an autologous bone marrow derived CD34+ cell product at four dose levels. The secondary objective of the study is to assess the effect on cardiac function and infarct region perfusion. A concurrent patient group meeting eligibility but not receiving CD34+ cells will be evaluated similar to the treated group to assess the rate of significant spontaneous improvement in cardiac function without CD34+cell infusion.

Certain types of cells located in bone marrow may help the body recover after an injury. These cells may be able to help the body repair heart muscle that has been damaged from a heart attack. NX-CP105 is a new investigational drug that is made up of these special types of bone marrow cells, which come from another person. NX-CP105 has not been approved for sale or general use by the Food and Drug Administration (FDA), and this study will be the first time that NX-CP105 is given to human beings. This study is being conducted to see if there are any side effects associated with with NX-CP105 and whether NX-CP105 may help the body repair heart muscle that has been damaged from a heart attack. Three different doses of NX CP105 will be tested in this study, starting with the lowest dose first. Patients who decided to participate in the study will have a heart catheterization procedure during which a narrow tube is inserted into an artery (type of blood vessel) in the groin and passed to the heart. A second narrow tube will be inserted into a vein (type of blood vessel) in the groin and passed to your heart. A device will be passed through the second tube. This device will be used to inject NX-CP105 cells directly into your heart muscle.

The purpose of this study is to evaluate whether erythropoietin can help limit the damage to the heart in patients with acute heart attacks.

The purpose of this study is to see if a naturally-occurring hormone called erythropoietin changes the action of platelets in the blood. Patients with heart attacks are treated with medicines to reduce the clotting action of platelets. This study is trying to determine whether erythropoietin alters the clotting action of platelets in patients receiving anti-platelet medicines. It is important to understand the effects of erythropoietin on platelets since preliminary studies in animals suggest that erythropoietin may protect the heart from damage during a heart attack.

The purpose of this study is to determine whether raising "good cholesterol" with a drug based on the vitamin niacin, while lowering "bad cholesterol" with a statin drug, can prevent more heart disease than the statin alone.

The purpose of this study is to determine if pioglitazone is effective in preventing future strokes or heart attacks among non-diabetic persons who have had a recent ischemic stroke.
