Here we are going to introduce some facts about the Cardiac Risk Markers. We will briedly describe the significance of Cardiac Risk Markers, how they work ,the factors which affect the accuracy of them and how to prepare for a Cardiac Risk Markers Test. Are you ready to ride with us?
Cardiac Markers are indicative of myocardial infarction and minor injuries to the heart,which include creatine kinase (CK) isoenzyme (CKMB), aspartate aminotransferase (GOT/AST), lactate dehydrogenase enzyme (LDH), hydroxybutyrate dehydrogenase (HDBD), myoglobin, and troponin,etc,. Cardiac Markers Test detect those substances that are released into the bloodstream following heart damage and stress, which can provide valuable information about the heart's health. It helps evaluate the risk of various cardiac conditions such as heart failure, coronary artery disease, and myocardial infarction. It can also be used for monitoring after surgery or diagnosis of a heart condition by the doctor.
Cardiac risks markers usually include creatine kinase (CK), lactate dehydrogenase (LDH),creatine kinase (CK) and isoenzyme (CKMB). These enzymes can leak out from damaged muscle cells and spill into the bloodstream if there's a rupture in the cell membrane. The evaluation of high level of these Cardiac markers provide you with a good idea of what is happening inside your body. Cardiac markers are often analyzed in blood tests to help doctors diagnose the condition of the heart. If the patient’s blood test shows an elevation in those cardiac markers ,it suggests that the patient has cardiac damage .It is important for patients with high levels of cardiac markers to be periodically monitored, as these proteins may increase degradation-inducing enzymes and otherwise damage the heart.
The results of cardiac markers tests are found in nanograms per milliliter (ng/mL). It is rare for those who are healthy and young to have any cardiac troponin, a protein that is released during any damage of the heart, in their blood. Troponin I levels are usually less than 0.12 ng/mL whereas levels of Troponin T are less than 0.01 ng/mL.
Although the normal results may differ, a cardiac troponin level of more than the 99th percentile of the reference range indicates a heart attack or heart muscle damage. The following factors affect your test results:
Your doctor may be better able to read out your results to you and explain what it means for your health.
How to Prepare for a Cardiac Risk Markers Test？
It is recommended to check with the doctor regarding the diet, before you go to the lab for giving the blood sample. Apart from this, there is no preparation required to ensure the sample quality.Have a good rest and completely relax before you taking the test .It might help you getting a more accurate result.
The blood test to determine cardiac markers test involves the use of needles that are safe in most cases. The temporary side effects or risks may include the following:
Sting or pain at the site of injection
Pay attention to observe the bleeding situation of the blood drawing port and keep it clean and dry after blood drawing.
