What does it mean when your CK-MB is high?

If you have higher than normal CK-MB enzymes, it may mean you have an inflammation of the heart muscle or are having or recently had a heart attack. If you have higher than normal CK-BB enzymes, it may mean you have had a stroke or brain injury.

What is normal CK-MB level?

Normal reference values for serum CK–MB range from 3 to 5% (percentage of total CK) or 5 to 25 IU/L.

Is CK-MB specific for heart?

CKMB is the heart specific isoenzyme and has been the gold standard method for the diagnosis of AMI in many laboratories. It exists in large quantity in heart muscle, but is not totally cardiac specific and exists also in skeletal muscles and other tissues.

Is CK-MB elevated in heart failure?

CK-MB was found to be elevated in 19 patients, most of whom had inflammatory heart disease. However, they found no correlation between CK-MB activity in serum and the severity of heart failure21.

What is a dangerously high CK level?

In rhabdomyolysis, the CK levels can range anywhere from 10 000 to 200 000 or even higher. The higher the CK levels, the greater will be the renal damage and associated complications.

What is the clinical significance of CK-MB?

This test helps your healthcare provider figure out if you’re having a heart attack. Measuring CK-MB used to be a common tool for diagnosing heart attacks, but healthcare providers use it less often today. Cardiac troponin is now the test of choice for finding a heart attack.

How can I lower my CK-MB level?

In conclusion, nitroglycerin reduces CK and CK-MB release and hence calculated infarct size, particularly when treatment is begun within the first 8 hours after onset of symptoms.

Does troponin or CK-MB rise first?

The CK-MB rises in the serum at 4–9 h after the onset of chest pain, peaks ~24 h and returns to baseline values at 48–72 h. The one advantage of CK-MB over the troponins is the early clearance that helps in the detection of reinfarction.
