Myocardial ischemia results from the temporary lack of oxygen; if ischemia is prolonged, it could result in permanent damage to the heart muscle. This condition is called myocardial infarction, commonly known as a heart attack.
ischemia
After an extended period of time, a myocardial infarction (heart attack). In the short run, the body may try and compensate for the low blood supply bringing oxygen and increase the heart rate or the cardiac output.
When your heart cells are not working or stop working, you will die seconds after.
it stops beating
High Blood pressure.
When blood supply to the heart is blocked what happens is a myocardial infarction which can result in death.
The heart muscle is not getting enough blood. The blood supply is actually so important that the flow from the large aorta has an artery that goes to the muscle's surface before it goes to the rest of the body. If this can not be 'fixed' in someway, the heart muscle die from lack of enough oxygen.
Ischemia occurs when there is not enough oxygenated blood reaching the cardiac muscle cells.
The heart moves the blood all over the body the heart it self is no exception. The heart is a cardiac muscle.
This is not a question please rephrase.
The heart muscle is supplied by blood vessels called coronaries.
The coronary arteries because they supply fresh blood to the heart's own muscle. The heart stops pumping if its muscle wall doesn't get enough blood. The coronary arteries are what supply blood to the heart itself and they are pretty small and narrow- they can't handle even a small clot.
The circulatory system = the heart + the blood vessels. The heart is a muscle, but the muscle fibers are slightly different to skeletal muscle. Arteries has a thin layer of muscle cells that surround them so that they can constrict or expand the blood vessels in order to regulate blood pressure.
No. A form of involuntary muscle known as cardiac muscle pumps the blood through the heart.
The myocard (cardiac muscle), the muscle that makes your heart pump, needs oxygen to function. This oxygen is distributed through the blood that flows in the coronary arteries, which lie around the cardiac muscle. When there is not enough oxygen in your blood, the cardiac muscle does not get enough oxygen to fully function and your heart will not be able to function, over time. This starts at about 3 minutes after stopping to get oxygen.
