It is the supply of oxygen to the heart; the oxygen is carried by the blood. When there's insufficient blood supply, oxygen supply is low too, and angina results. See http://en.wikipedia.org/wiki/Angina_pectoris

Why does earth have q liquid water supply and the moon does not?
I think that the earth does have a water supply since it has oxygen and gravity. On the moon I think it doesn't have oxygen or gravity. I'm not sure. This answer was just a guess.
What activity would best keep the world's oxygen supply from decreasing?
Planting trees in forests that have been harmed would best keep the world's oxygen supply at a healthy level.
Can thermal pollution reduce the oxygen supply in an aquatic ecosystem?
maybe
How long can the heart muscle be deprived of adequate oxygen supply?
30 minutes
What is the equation for burning carbon in limited supply of oxygen to form carbon monoxide?
Incomplete reaction of carbon and oxygen: 2C + O2 --> 2CO
Does cardiac muscle have more mitochondria and depend less on a continual supply of oxygen than does skeletal muscle?
no
Why do your brain lack of oxygen?
reduced blood supply to brain.it may be due to obstruction of arteries which supply brain,thrombus formation,reduced cardiac output...............
What is a description of cardiac tamponade?
The condition keeps the rest of the body from getting the necessary supply of oxygen and can cause dangerously low blood pressure.
Do muscles need oxygen to work?
Yes, cardiac muscles cells have a very high oxygen demand, since they are constantly in motion. This is why any shortage of oxygen causes angina, or if the oxygen deprivation is long enough, it causes death of the muscle cells - what is commonly called a heart attack.
Can Low hemoglobin and stroke?
Yes. A heart attack is when the cardiac muscle dies due to loosing its oxygen supply. Haemoglobin carries oxygen around the body and if it is continually dropping it will at some point reach a critical stage where oxygen cannot be supplied to the myocardium and it will infarct.
Which blood vessels supplies the heart with its own blood supply?
Re-oxygenated blood flows into the heart via the pulmonary vein. However, these blood will leave the heart, and supply oxygen to the body. The heart has its own circulation; the cardiac arteries (supply the oxygenated blood)and the cardiac veins (drain the collected venous blood).
What is blood supply of cardiac muscle?
Coronary arteries
If cardiac muscle is deprived of its normal blood supply damage would primarily result from?
loss of oxygen.... the mitochondria in the cardiac muscle need it to continue to produce energy to keep the muscles contractiong without it the muscles seize from lactic acidosis a byproduct anaerobic respiration.
What is exertional syncope?
I think that exertional syncope is a kind of cardiac syncope. During exertion the patient with heart disease would be unable to supply enough oxygen to the brain, causing dizziness.
What is a possible crossword puzzle answer for supply with oxygen?
Supply with oxygen= aerate
What will happen if your cardiac muscles contracts without resting?
if there z the continuos contraction then it leads to cardiac arrest.by which the blood supply also gets ceases and it leads to decreased transport of oxygen .which finally leads to apnoea r dysnoea.sometimes there occurs also a condition of hypertension at once.
How long can cardiac muscle be deprived of oxygen before the cardiac muscle cells start to die?
5 minutes
