Ischaemic Heart disease (coronary artery disease or CAD) is a condition in which atheroma (fatty deposits) builds up in the linings of the walls of the coronary arteries. This causes a narrow artery and reduced blood flow to the heart muscle. This process can occur in other arteries of the body. Important arteries which, if affected can have medical consequences, are the carotid arteries in the neck, (which supply blood to the brain), and the femoral /popliteal arteries in the legs. In these situations a bruit (noise) may be heard over the area affected (i.e. carotid or femoral arteries), through a stethoscope.
Atheroma at a certain point, results in obstruction to the blood flow of the coronary arteries, which leads to the inability to provide adequate oxygen to the cardiac muscle, therefore an inability to meet demand. Therefore when the heart has to work harder (i.e. in exercise, or in certain medical conditions, such as hyperthyroidism or anaemia insufficient blood reaches the heart muscle. The muscle is then said to be ischaemic. Ischaemia can also occur from coronary artery spasm, or when the heart is enlarged from increased strain, such as in high blood pressure (hypertension) or tightness at the root of the main blood vessel leading from the heart (aortic stenosis).
In practice, a reduction in coronary artery diameter by 50% or more, on coronary arteriogram is judged significant, and will most likely cause symptoms of angina.
Myocardial Ischaemia is manifested in central chest pain, causing stable angina, unstable angina and myocardial infarction (MI).

What is ischemic heart tissue?
Ischemia occurs when there is not enough oxygenated blood reaching the cardiac muscle cells.
Patient experiences severe ischemia what can happen to heart?
Ischemia is a medical term meaning insufficient oxygen ... usually caused by insufficient blood flow. If the ischemia is occurring in the heart it will probably cause some type of cardiac problem: anything from mild cardiac failure (not pumping all the blood that the body demands) to pain (angina) to death of some or all of the cardiac muscle (a heart attack).
When get a person heart attack?
if there is any block in aorta( vein carrying oxygenated blood) and this leads to cardiac arrest which is in turn heart attack
Which is better cardiac output or cardiac index?
Cardiac index (CI) is better. Because you count with the body surface. When you have a cardiac output (CO) of certain value in a small and thin person, the same value can be insufficient in a tall and fat person. In CI you devide CO by the person's surface and you get much better idea of what's going on ;)
What structures provide oxygenated blood to the heart?
Well the pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart but the cardiac muscle itself receives oxygenated blood from the coronary arteries.
Group of cardiac disabilities resulting from an insufficient supply of oxygenated blood to the heart?
Ischemic Heart Disease
Why are cardiac vessels necessary?
The heart, like any other organ, needs oxygenated blood. Cardiac vessels serve this purpose.
What is ischemic heart tissue?
Ischemia occurs when there is not enough oxygenated blood reaching the cardiac muscle cells.
What does the heart send to all of the cells?
The heart or cardiac muscle sends oxygenated blood to keeps cells alive.

What is the name of the blood vessel which carries blood to the cardiac muscles?
The left and right coronary arteries carry oxygenated blood from the base of the aorta to the heart muscle.
What is a hole in the heart?
A congenital defect in the heart septum, resulting in inadequate circulation of oxygenated blood (a cause of blue baby syndrome).
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).
Where is the cardiac septum located?
It is located between the right and left pumps of the heart. One of its main functions is to separate the oxygenated blood of the left pump from the oxygen poor blood of the right pump.
