Active clinical trials for "Infarction"

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.

The purpose of this study is to determine whether brief periods of ischemia performed just at the time of reperfusion -postconditioning- can reduce coronary endothelial dysfunction and infarct size in humans

This trial was designed to examine the efficacy of a brief versus a standard prolonged (18 hours) infusion of eptifibatide in preventing troponin I release following successful coronary stenting.

One emerging concept is that some form of injury or inflammation is a prerequisite for the success of circulating-cell participation in differentiated tissue structure and function. Once reperfusion is achieved in acute myocardial infarction, an intense inflammatory cascade is unleashed. The architecture of the left ventricle rearranges, leading to ventricular remodeling. The "homing process"involves stem cell migration to the sites of injury or ischemia, which provides an environment that is favorable to growth and function. This microenvironment is a stimulus for homing and differentiation of stem cells of the appropriate lineage. It increases vascular permeability and expression of adhesion proteins like integrin, along with homing receptors that facilitate the attachment, which is mediated by cell-to-cell contact and chemoattractant release from local tissue injury.The migratory capacity of stem cells might be dependent on natural growth factors such as vascular endothelial growth factor (VEGF) , stromal cell-derived factor-1 (SDF-1)and stem cell factor (SCF).The expression of VEGF ,SDF-1 and SCF is highly up-regulated in hypoxic tissue, supporting the hypothesis that these factors may represent homing signals crucial to the recruitment of circulating progenitor cells to assist the endogenous repair mechanisms in the infarcted tissue. This study will examine whether cardiac rehabilitation increases the concentration of stem cell factors released into the bloodstream and if these factors are correlated with the improvement of heart function.

The purpose of this study is to assess whether abciximab is associated with additional benefit in patients with AMI treated with PCI after high dose clopidogrel loading.

OBJECTIVE: to evaluate the safety and efficacy of a brief intracoronary infusion of ADO applied at the time of reperfusion to limit infarct size and LV remodelling in patients with ACSST submitted to primary ACTP. DESIGN: Multicentric, prospective, randomised, parallel, placebo-controlled double-blind study. PATIENTS: 200 patients older than 18 with ACSST and without prior myocardial infarction receiving primary PTCA within 6 hours after symptom onset.

Randomized, control, open label, multicentre clinical study. The patient who are in accordance with subject inclusion and exclusion criteria will be randomized to A group: Routine treatment B group: Routine treatment+ Cilostazol; C group : Routine treatment + Probucol; D group: Routine treatment+ Cilostazol+ Probucol .

The primary objective was to demonstrate a difference between two insulin strategies, one targeting postprandial (PP) hyperglycemia and the other targeting fasting and interprandial hyperglycemia, on time until the first combined adjudicated cardiovascular (CV) event (primary outcome defined as CV death, nonfatal myocardial infarction [MI], nonfatal stroke, coronary revascularization, or hospitalized acute coronary syndrome).

The purpose of this study is to determine if intense control of high glucose levels in patients treated with angioplasty for heart attack has anti-inflammatory and anti-thrombotic effects.
