Active clinical trials for "Myocardial Infarction"

The purpose of the study is to test the efficacy and safety of bupropion SR for smokers hospitalized with acute cardiovascular disease.

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.

To evaluate whether nicorandil as an adjunctive therapy for AMI reduces myocardial infarct size and improves regional wall motion

The purpose of this study is to examine whether the lowering of blood homocysteine levels by treatment with B vitamins can prevent cardiovascular disease

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.

To evaluate the impact of community educational interventions on patient delay time from onset of symptoms and signs of an acute myocardial infarction (AMI) to arrival at a hospital Emergency Department (ED). Also, to study the impact of community educational interventions on use of Emergency Medical Services (EMS) and EDs, on thrombolytic therapy, and on AMI case fatality.

To assess the effect of non-surgical reperfusion on infarct size in patients with acute myocardial infarction.

In TIMI I, to assess the relative thrombolytic activity and side effects of intravenous recombinant tissue-type plasminogen activator (rt-PA) versus intravenous streptokinase in patients with acute myocardial infarction. In TIMI II, to assess whether intravenous rt-PA given in the early hours of acute myocardial infarction should be followed by percutaneous transluminal coronary angioplasty (PTCA).

Radial approach is widely established in cardiac diagnostic and therapeutic treatments. It has been shown to decrease bleeding, vascular problems, and mortality rates when compared to the femoral approach. It also offers better comfort to patients through early mobility and lowers hospital expenses. Previously, there were no specific devices for radial artery hemostasis. Many different types of dressings were used in various hospitals with no standardization. This raises the question of whether specific devices surpass dressings in terms of patient comfort, time required to maintain hemostasis, and vascular complications. The primary goal of this study was to examine the effectiveness of compression dressings and hemostatic wristbands on patients undergoing cardiac procedures via radial approach in terms of patient comfort, time required to maintain hemostasis, and vascular problems. The hemostatic wristband TR BandR (Terumo Corporation, Tokyo, Japan) was utilized in one group, while compressive elastic dressing, standardized as 13 threads gauze overlapped, opened, longitudinally pleated once and wrapped, making a 5-cm long cylinder, 1-cm in height, was used in the other.
