Infarction - tissue death
Myocardium - heart muscle
MI is casued by lack of blood flow to the heart muscle
Ischaemia is the lack of blood flow to the heart muscle
MI occurs when there is cell death
Changes in cardiac proteins (biomarkers) are indications of myocardial infarction (MI)
Myocardial infarction can cause cardiac arrest
Myocardial infarction can lead to heart failure
Atherosclerosis is the most common cause of myocardial infaraction
Loosened plaques can lead to a blood clot
Atherosclerosis - buildup of cholesterol and fibrous tissue in plaques in the wall of coronary arteries
Bad blood flow can cause heart cells to die
The dead tissue of the heart will not grow back
A scar made of collagen dies
Cells need oxygen to produce energy
Tissue death and heart scarring alter the conduction pathways of the heart
Dead collagen tissue does not conduct impulses well
Ischemia causes heart tissue to die
