Cardiac markers are a way for doctors to measure and evaluate heart function. So, what are these markers? Well, they used to be things such as enzymes but today most are not. Enzymes are still used, just not as often because there are better and more accurate methods. Of the entire list of current cardiac marker tests used, troponin remains to be the most common and the most effective.
Troponin is often used in modern evaluations because it is the most specific test available. It is highly sensitive which means more accurate readings. Troponin is not a cardiac enzyme and it is far superior to other marker methods.
Troponin is released when a myocardial injury occurs. The elevations are study to determine what the precise problem is and even calculate the size of an infarction. This makes the troponin cardiac marker test a much needed and highly regarded bio-tool.
Depending on which cardio marker is used the process of elevation in the blood can take anywhere from two to twenty four hours of monitoring before an increase can be noticed and recorded. They are then determined in a lab and that can take time to complete. This means that in acute cases these markers can not help because they take too much time. ECG would then be more beneficial to the patient.
