Understanding Lab Tests for Myocardial Infarction
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
A myocardial infarction, commonly known as a heart attack, occurs when blood flow to a part of the heart muscle is blocked, causing tissue damage. Blood tests play a crucial role in diagnosing this condition by detecting specific markers that are released when heart muscle cells are damaged.
Recommended Test
Aldolase
Aldolase levels may be elevated in myocardial infarction, indicating damage to heart muscle cells. This occurs because when muscle tissue breaks down during a heart attack, aldolase is released into the bloodstream, making it a useful marker for detecting heart muscle damage.

The Role of Blood Tests in Heart Attack Diagnosis
When heart muscle cells are damaged during a myocardial infarction, they release various enzymes and proteins into the bloodstream. These cardiac markers can be detected through blood tests, helping healthcare providers confirm the diagnosis, assess the extent of damage, and monitor the patient's response to treatment.
Understanding Your Test Results
Elevated aldolase levels in the context of chest pain or other heart attack symptoms can support the diagnosis of myocardial infarction. However, this test is typically used alongside other cardiac markers and clinical evaluation for a comprehensive assessment of heart muscle damage.
