Strengthening Transplantation Effects of Bone Marrow Mononuclear Cells With Atorvastatin in Myocardial Infarction

2014-08-27 03:19:13 | BioPortfolio

Summary

The benefit of current stem cell transplantation therapy for myocardial infarction is limited by low survival rate for stem cell. The purpose of this study is to test whether intensive Atorvastatin therapy can improve the outcome of patients with impaired left ventricle function after myocardial infarction who underwent intracoronary transfer of autologous bone marrow cells.

Description

The major challenge to a successful stem cell therapy for myocardial infarction is the low survival rate of implanted cells in the damaged tissue. Atorvastatin, an HMG-CoA reductase inhibitor, has multiple biological activities independent of cholesterol-lowering action.This study is performed to find out more information about the strategy with Atorvastatin therapy to improve the survival of implanted cells. autologous bone marrow stem cells transplantation. Patients between 30 and 80 years of age who receive autologous bone marrow stem cell transplant at the Fuwai cardiovascular hospital may be eligible for this study. These patients receive autologous bone marrow cells transplantation intracoronary undergoing Percutaneous Coronary Intervention with regular or high dose of Atorvastatin treatment. The objective evaluations will be performed at baseline and during 12 months follow-up.

Heart function tests may include the following:

1. Electrocardiogram (EKG) evaluates the electrical activity of the heart. Electrodes placed on the chest transmit information from the heart to a machine.

2. Echocardiogram (Echo) is an ultrasound test that uses sound waves to create an image of the heart and examine the function of the heart chambers and valves.

3. Gated acquisition scan is a nuclear medicine test that uses a small amount of radioactive chemical injected into a vein. A special scanner creates an image of the heart for examining the beating motion of the muscle.

4. MRI evaluates function of the heart chambers the beating motion of the muscle.

Medical and Biotech [MESH] Definitions

MYOCARDIAL INFARCTION in which the anterior wall of the heart is involved. Anterior wall myocardial infarction is often caused by occlusion of the left anterior descending coronary artery. It can be categorized as anteroseptal or anterolateral wall myocardial infarction.

A myocardial infarction that does not produce elevations in the ST segments of the ELECTROCARDIOGRAM. ST segment elevation of the ECG is often used in determining the treatment protocol (see also ST Elevation Myocardial Infarction).

A clinical syndrome defined by MYOCARDIAL ISCHEMIA symptoms; persistent elevation in the ST segments of the ELECTROCARDIOGRAM; and release of BIOMARKERS of myocardial NECROSIS (e.g., elevated TROPONIN levels). ST segment elevation in the ECG is often used in determining the treatment protocol (see also NON-ST ELEVATION MYOCARDIAL INFARCTION).

MYOCARDIAL INFARCTION in which the inferior wall of the heart is involved. It is often caused by occlusion of the right coronary artery.

Mononuclear cells with pronounced phagocytic ability that are distributed extensively in lymphoid and other organs. It includes MACROPHAGES and their precursors; PHAGOCYTES; KUPFFER CELLS; HISTIOCYTES; DENDRITIC CELLS; LANGERHANS CELLS; and MICROGLIA. The term mononuclear phagocyte system has replaced the former reticuloendothelial system, which also included less active phagocytic cells such as fibroblasts and endothelial cells.
