What are the causes of silent ischemia?
Silent ischemia usually is caused by emotional or mental stress or by exertion, but there are no symptoms.
What is exercise induced ischemia?
Exercise-induced ischemia refers to a condition where there is a temporary decrease in blood flow to the heart muscle during physical activity, often due to narrowed or blocked coronary arteries. This reduced blood flow can lead to symptoms such as chest pain or discomfort, known as angina. It indicates that the heart is not receiving enough oxygen to meet the increased demands of exercise. Exercise-induced ischemia is often assessed using stress tests to identify underlying heart conditions.
What does scintigraphic evidence of Adenosine-induced ischemia in the lateral wall?
Scintigraphy imaging showing Adenosine-induced ischemia in the lateral wall indicates reduced blood flow to that area of the heart during stress. This could suggest potential blockages or narrowing of the coronary arteries supplying blood to the lateral wall, which may require further evaluation and treatment to prevent cardiac complications.
Causes of lateral wall ischemia?
Blockage by plaques
Anteroseptal wall ischemia?
Anterior Wall Ischemia: [blockage in the Left Anterior Descending Artery]
What are cardiovascular stress test codes used for?
exercise-induced studies, pharmacologically-induced studies,
Can stress cause ischemia?
Ischemia almost always is caused by blockage of an artery, usually due to atherosclerotic plaque.
What causes a stress?
Verticle stress causes monocline. Verticle stress causes monocline.
When the temperature of a body is increased the stress induced will be?
When the temperature of a body increases, the stress induced is typically thermal stress, which arises due to the expansion of materials. If the body is constrained and unable to expand freely, this thermal expansion leads to compressive or tensile stresses. The magnitude of the induced stress depends on the material's coefficient of thermal expansion and the temperature change. If the body can expand freely, no thermal stress will develop.
What is the amount of axial stress on a member which is subjected to a sudden load when compared to load applied gradually?
The maximum stress induced in a body due to suddenly applied load is twice the stress induced when the same load is applied gradually
What are the causes of osteochondroses?
Many theories have been advanced to account for osteochondrosis, but none has proven fully satisfactory. Stress and ischemia (reduced blood supply) are two of the most commonly mentioned factors. Athletic young children are often.
What is the thermal stress equation used to calculate the stress induced in a material due to changes in temperature?
The thermal stress equation used to calculate stress induced in a material due to temperature changes is given by: ET where: thermal stress E Young's modulus of the material coefficient of thermal expansion T change in temperature
