Question
Which of the following blood tests is most indicative of cardiac damage?
1 point
- A. Lactate dehydrogenase
- B. Complete blood count
- C. Troponin I
- D. Creatine kinase
Solution
The blood test most indicative of cardiac damage is C. Troponin I.
Here's why:
-
Troponin I is a protein found in heart muscle and is released into the blood when there is damage to the heart.
-
In the event of a heart attack, levels of Troponin I will begin to rise within a few hours and can remain elevated for up to two weeks.
-
Other tests like Lactate dehydrogenase, Complete blood count, and Creatine kinase can also indicate problems with the heart, but they are not as specific as Troponin I.
-
For example, Lactate dehydrogenase and Creatine kinase can be elevated in many conditions including muscle damage, while Complete blood count is a general test that can indicate a wide range of conditions.
-
Therefore, among the options given, Troponin I is the most indicative of cardiac damage.
