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.
Elevated liver enzymes occur when there is damage or inflammation on the liver. The damage causes the liver cells to produce a higher amount of certain chemicals, which are deposited into the bloodstream. The liver enzymes that are usually elevated in the blood include alanine transaminase, or ALT, and aspartate transaminase, or AST.
