the difference between aortic diastolic and right atrial diastolic pressure; a determinant of the blood flow to cardiac muscle.
Coronary perfusion pressure is responsible for coronary blood flow. It is the difference between the diastolic pressure of the aorta and the end diastolic pressure of the left ventricle.
also called coronary angiogram, is a test to check your heart and coronary arteries. It is used to check blood flow in the coronary arteries , blood flow and blood pressure in the chambers of the heart , find out how well the heart valves work, and check for defects in the way the wall of the heart moves. In children, this test is used to check for heart problems that have been present since birth (congenital heart defect).
Men who are 45 years of age and older and women who are 55 years of age and older are considered to be at risk. Risk also increases with age.
To open an artery near the heart
The symptoms of coronary artery disease don't appear until the artery is 70 percent blocked. Moreover, women who suffer from a heart attack tend to experience different symptoms. While some of the common symptoms of coronary artery disease include fullness or pressure in the chest often extending to the arm, jaws, and neck area ; breathless; dizziness; and nausea, women reported suffering from abdominal and mid-back pain, indigestion, and extreme fatigue.
Bigger volume means less pressure on the sides, so pieces of junk can stick easier, rather than being blasted through in the small vessels.
15-70
Think of it as like a shower head. The more you turn up the dial (blood pressure), the stronger the water shoots out of the head (coronary perfusion rate).
Well pulse pressure is systolic (top) minus diastolic (bottom). So the value you get should be between 30-49 to be normal.
Transmural perfusion pressure represents the amount of pressure in the coronary arteries that supply the layers of the heart muscle (the TRANSMURAL part). The formula is: Aortic diastolic pressure - LVEDP (L Ventricle End Diastolic Pressure). Keep in mind the coronaries ONLY receive blood during diastole because of the twisting forces applied on the heart during systole.

There are different signs of coronary heart disease such as heart pains or feelings of low blood pressure. Thoughts of this should be consulted with a doctor.
There are baroreceptors located in the aorta and at the carotid bifurcation. These function to modulate the cardiac output and maintain normal blood pressure and an adequate perfusion pressure to the brain.
haemorrhage prevented by platelet aggregation and agglutination (clotting) and vasoconstriction to maintain blood pressure/perfusion pressure. formation of clot through platelet clumping and binding with protein fibrin.

Think of these as the 'fight or flight' stimulants.They increase heart rate, heart volume and contraction force.Blood flow to the limbs is increased.Blood flow to the digestive organs is reduced.Broncho dilation, pupil dilation... there are many and varied effects across the body.
It means that there is something (could be many different things) obstructing the coronary arteries (i.e.. the arteries in the heart). Her uncle could be experiencing many different symptoms such as pressure in the chest, nausea, or sweating.
