What do Abnormal Results Mean?

Because LDH can be found in many tissues in the body, total LDH is not specific for heart disease. Normally, the concentration of LDH-2 is greater than LDH-1. However, after a heart attack, the concentration of LDH-1 is generally higher than that of LDH-2. (This is called a "flipped" LDH pattern.) The LDH level rises within 24 to 72 hours after a heart attack, peaks in 3 to 4 days, and returns to normal in about 14 days.

Greater-than-normal LDH isoenzyme levels may be seen in:

Heart attack
Hemolytic anemia
Hypotension
Infectious mononucleosis
Intestinal ischemia (blood deficiency) and infarction (tissue death)
Liver disease (e.g., hepatitis)
Muscle injury
Muscular dystrophy
Pancreatitis
Pulmonary (lung) infarction (tissue death)
Stroke
Ischemic cardiomyopathy
