Cardiac enzymes ― also known as cardiac biomarkers ― include myoglobin, troponin and creatine kinase. Historically, lactate dehydrogenase, or LDH, was also used but is non-specific. Cardiac enzymes ...

The cardiac troponin test detects damage to the heart muscle. Troponin is a protein that appears in the blood only when the heart muscle is damaged, as in a heart attack. There are other causes of ...

A new study out of Sweden shows that a rapid test for a cardiac enzyme, when combined with a normal electrocardiogram, rules out a heart attack with 99.8 percent reliability. What are the implications ...

Blocking the fat-busting enzyme lipoxygenase with a synthetic inhibitor throws the immune system's innate inflammatory response out of whack, compromising cardiac repair during acute heart failure, ...

A creatine kinase test is a blood test that measures levels of an enzyme called creatine kinase. This enzyme supports energy ...
