What is transmural perfusion pressure?
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.
What is reversible perfusion abnormalities?
Reversible perfusion abnormalities refer to areas of the heart that show reduced blood flow during stress testing but improve when the stress is removed. This typically indicates that the reduction in blood flow is due to a temporary blockage or narrowing of the coronary arteries, rather than permanent damage to the heart muscle. Reversible perfusion abnormalities are often seen in patients with coronary artery disease.
What is the severely reduced perfusion in the inferior wall?
Severely reduced perfusion in the inferior wall of the heart typically indicates compromised blood flow to that area, often due to coronary artery disease or blockage in the coronary arteries supplying the inferior wall, such as the right coronary artery. This can lead to ischemia, resulting in symptoms like chest pain or heart failure. If left untreated, it may progress to myocardial infarction (heart attack), damaging the heart muscle. Timely medical intervention is crucial to restore blood flow and prevent further complications.
What type of circulation provides blood to the heart's tissues?
The coronary circulation provides blood to the heart's tissues. The coronary circulation includes the coronary arteries and coronary veins.
The process of carrying blood to the tissues is described as?
The process of carrying blood to the tissues is known as perfusion. This involves the delivery of oxygen and nutrients to the cells in the tissues via the blood vessels. Adequate perfusion is essential for the proper functioning of tissues and organs in the body.
Coronary perfusion pressure?
the difference between aortic diastolic and right atrial diastolic pressure; a determinant of the blood flow to cardiac muscle.
What is the normal value of coronary perfusion pressure?
The normal value of coronary perfusion pressure is typically around 60-80 mmHg. This pressure gradient is essential for adequate blood flow to the coronary arteries, which supply the heart muscle with oxygen and nutrients. Maintaining a sufficient coronary perfusion pressure is crucial for overall cardiac function and health.

What are some common diet-related diseases in Singapore?

What is the movement of blood around heart tissue called?
The movement of blood to the heart tissue is called myocardial perfusion. In order for the myocardium (the heart muscle) to get oxygen and nutrients it has its own circulation providing a blood supply known as the coronary circulation. The coronary arteries (oxygenated blood vessels of the heart) supply nutrients and oxygen to the heart muscles between heart beats when the heart is relaxed (during diastole). Blood is routed from the surface of the heart muscle to deeper tissues of the myocardium. After delivering oxygen and nutrients to the cells of the heart, coronary veins pick up the blood and route it into the pulmonary (lungs) circulation where it can become re-oxygenated and return oxygenated blood back to the heart.
What is the severely reduced perfusion in the inferior wall?
Severely reduced perfusion in the inferior wall of the heart typically indicates compromised blood flow to that area, often due to coronary artery disease or blockage in the coronary arteries supplying the inferior wall, such as the right coronary artery. This can lead to ischemia, resulting in symptoms like chest pain or heart failure. If left untreated, it may progress to myocardial infarction (heart attack), damaging the heart muscle. Timely medical intervention is crucial to restore blood flow and prevent further complications.
How is cerebral perfusion pressure calculated?
Cerebral perfusion pressure (CPP) is calculated using the formula: CPP = Mean Arterial Pressure (MAP) - Intracranial Pressure (ICP). Mean Arterial Pressure is typically estimated using the formula MAP = (SBP + 2 * DBP) / 3, where SBP is systolic blood pressure and DBP is diastolic blood pressure. By subtracting the intracranial pressure from the mean arterial pressure, CPP provides an indication of the pressure gradient driving blood flow to the brain. Maintaining adequate CPP is crucial for ensuring sufficient cerebral blood flow and oxygen delivery.
Which blood vessels supply blood to the heart muscle?
The heart muscle is supplied with oxygenated blood by the coronary arteries. Along with the oxygenated blood, the arteries also supplies the heart muscle with nutrient-filled blood.
Which of the choices below does not involve tissue perfusion?
Tissue perfusion is the amount of blood that the tissues receive during circulation. When a person has decreased tissue perfusion, the tissues are receiving inadequate blood supply.
What are the signs of Coronary Heart Disease?
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.
