What are cardiac markers?

Cardiac markers are substances released into the bloodstream when the heart is damaged or under stress. Analysing these markers can provide valuable information about heart health and diagnose various cardiac conditions.

Why is cardiac marker analysis performed?

Cardiac marker analysis is crucial for diagnosing and monitoring heart-related conditions such as heart attacks, heart failure, and myocardial infarction. It helps healthcare professionals assess the extent of cardiac damage and guide treatment decisions.
 

When should the test be performed?

Cardiac marker analysis is typically performed when there is suspicion of acute coronary syndrome, chest pain, or symptoms indicative of a heart problem. It may also be done as part of routine screening for individuals with risk factors for heart disease.
 

What type of sample is required?

Blood samples are commonly used for cardiac marker analysis. These samples are usually drawn from a vein in the arm using a needle.
 

Is any type of prior preparation necessary?

In most cases, no specific preparation is required before undergoing cardiac marker analysis. However, it's essential to follow any instructions provided by your healthcare provider regarding fasting or medication restrictions, if applicable.
 

How is the sample used?

Cardiac markers are measured using laboratory tests such as troponin, creatine kinase-MB (CK-MB), and myoglobin assays. These tests help determine the presence and severity of heart damage and guide treatment decisions.
 

What are the normal values?

Normal values for cardiac markers vary depending on the specific marker being measured and the laboratory performing the test. However, in general, elevated levels of cardiac markers indicate heart damage or stress.
 

What does it mean to have altered values?

Altered values of cardiac markers typically indicate underlying heart problems such as myocardial infarction (heart attack), myocarditis, or unstable angina. Elevated levels of cardiac markers suggest ongoing cardiac injury or stress and may warrant further evaluation and treatment.

Please note that normal ranges may vary depending on the laboratory and testing method used. Always consult with a healthcare professional for interpretation of test results and appropriate management.
