During a heart attack, heart muscle cells die due to lack of oxygen. Cardiac enzymes from the dying cells leak into the bloodstream. In addition to a heart attack, other cardiac diseases that can cause elevated cardiac enzymes include: -- heart failure, or weakness of the heart muscle. -- inflammation of the sac surrounding the heart, or pericarditis. -- inflammation of the heart muscle, or myocarditis.
There can be many causes of these symptoms. Cardiac enzymes are substances released by the heart muscle when it is injured - for example, during a heart attack (myocardial infarction) or a severe case of angina. There are a number of cardiac enzymes and the most common of these is called troponin. There are two types of troponin that can be measured from a blood sample: T and I. Most hospitals will usually only measure one or the other, and both are equally sensitive.
