What is adenosine cardiolite?

The Adenosine Cardiolite stress test is a diagnostic exam used to evaluate the supply of blood to your heart muscle. Your heart receives blood from the coronary arteries. If these arteries become partially blocked or narrowed, your heart will not receive the blood that it needs for proper function.

What happens during a cardiolite stress test?

During a nuclear stress test, first you will be injected with Cardiolite, a radioactive tracer, in the vein of your arm or hand. Cardiolite is taken up by the heart muscle through the coronary arteries in proportion to the blood flow to it. This material should not affect you in any way.

Which part of ATP contains the most energy?

Energy is stored in the covalent bonds between phosphates, with the greatest amount of energy (approximately 7 kcal/mole) in the bond between the second and third phosphate groups. This covalent bond is known as a pyrophosphate bond.

What does cardiolite mean?

This is a type of nuclear scanning test. It shows how well blood flows to the heart muscle. It’s usually done along with an exercise stress test on a treadmill or stationary bicycle. The average exercise time is usually less than 12 minutes.

Which is the highest energy form of adenosine?

Select the highest energy form of adenosine from the following images. Adenosine triphosphate (ATP) is the high-energy form of adenosine because it contains the most phosphate groups (three). This molecule fuels many different endergonic (energy-requiring) enzymatic processes in biological organisms.

What is the purpose of an adenosine Cardiolite stress test?

What is the purpose of an Adenosine Cardiolite stress test? The Adenosine Cardiolite stress test is a diagnostic exam used to evaluate the supply of blood to your heart muscle. Your heart receives blood from the coronary arteries.

Why does adenosine cause myocardial ischemia in CAD?

Depending upon the severity of coronary stenosis and coronary flow reserve limitation, a relative flow heterogeneity is induced. Adenosine generally does not cause myocardial ischemia. However, in a small percentage of patients with severe coronary artery disease (CAD), true ischemia may be induced because of a coronary steal phenomenon.

How does an adenosine injection affect the heart?

Adenocard (adenosine injection) exerts its effect by decreasing conduction through the A-V node and may produce a short lasting first-, second- or third-degree heart block.
