R74.02
Elevation of levels of lactic acid dehydrogenase [LDH]
Clinical Classification Guidelines
Medical Intelligence & Overview
Lactic acid dehydrogenase (LDH) is an enzyme found in many parts of the body, including the heart, liver, muscles, and kidneys. An elevation in LDH levels, identified by the ICD-10 code R74.02, can indicate a variety of health conditions. While increased LDH levels are often a sign of tissue damage or disease, they are not specific to one particular illness, making further investigations necessary for accurate diagnosis.
Causes & Symptoms
Clinical Causes: Tissue damage from conditions such as heart attacks, liver disease, or muscle injuries Certain types of anemia Some types of cancers, including lymphoma, leukemia, and metastatic tumors Hemolytic anemia, where red blood cells are destroyed prematurely Infections, such as bacterial or viral diseases that cause tissue destruction Liver disorders like hepatitis or cirrhosis Kidney disease Bone fractures or trauma Pancreatitis Severe infections, including sepsis
Key Symptoms: Fatigue and weakness Unexplained muscle pain or discomfort Swelling or inflammation in affected areas Symptoms related to the underlying cause, such as jaundice with liver issues or chest pain with heart conditions General malaise or feeling unwell Fever in cases of infection Shortness of breath or rapid breathing in some conditions
Diagnostic & Treatment
Diagnosis Path: A blood test measuring LDH levels is used to identify their elevation. This test is often performed alongside other laboratory tests to evaluate tissue damage or disease processes. Healthcare providers will review the patient's medical history, conduct a physical examination, and may order additional tests such as imaging studies, enzyme-specific tests, or biopsy procedures to determine the underlying cause of elevated LDH levels.
Treatment Protocols: Treatment strategies depend on the identified cause of the elevated LDH. For example, managing heart attacks or infections, treating liver or kidney diseases, or addressing cancer through specific therapies. In many cases, addressing the primary condition leads to a normalization of LDH levels. Supportive care, such as rest, adequate hydration, or pain management, may also be recommended as part of overall treatment. It’s important for patients to follow their healthcare provider’s guidance and attend regular follow-up appointments.
