regenerates
Ischemia occurs when there is not enough oxygenated blood reaching the cardiac muscle cells.
Yes, ischemia leads to heart arrest.
irreversible ischemia
Inferoapical ischemia is lack of blood flow below the apex.
reversible ischemia
Diastole is the relaxation phase of the heart.
The natural biologic response to repeated myocardial ischemia (insufficient oxygen levels in heart muscle) is angiogenesis, the growth of new collateral blood vessels. http://www.cardiumthx.com/science-technology-overview.html
A heart attack occurs when the blood flow is cut off to a portion of your heart muscle.
Angina pectoris, commonly referred to as just "angina", is chest pain caused by ischemia, or shortage of oxygenated blood supply, to the heart muscle. Unlike a heart attack, angina does not result in permanent damage to the heart muscle.
health professinals assumes that the patient is suffering from a ischemia of the heart and giving oxygen will resupply the heart muscle with high concentration of oxygen.
A heart attack.
