Early diagnosis of myocardial infarction by arginase activity determination
Insights
Arginase activity in blood serum is low in healthy individuals but rises sharply after myocardial infarction. This enzyme activity can help differentiate heart attacks from other cardiac conditions.
Area of Science:
- Biochemistry
- Cardiology
- Clinical Diagnostics
Background:
- Arginase (EC 3.5.3.1) activity is typically low in healthy blood serum.
- Elevated arginase levels are not observed in conditions like angina pectoris or cardiac failure.
Purpose of the Study:
- To investigate the diagnostic potential of serum arginase activity for myocardial infarction.
- To differentiate myocardial infarction from other cardiac ailments using arginase levels.
Main Methods:
- Measurement of arginase enzyme activity in blood serum.
- Comparison of arginase levels in patients with myocardial infarction versus other cardiac conditions.
Main Results:
- Serum arginase activity significantly increases within hours of myocardial infarction onset.
- Arginase levels return to normal within 3-5 days post-myocardial infarction.
- No significant increase in arginase activity was found in patients with angina pectoris, coronary insufficiency, or cardiac failure.
Conclusions:
- Serum arginase activity serves as a potential biomarker for early differential diagnosis of myocardial infarction.
- Arginase level determination can aid in distinguishing myocardial infarction from other acute coronary syndromes.
Abstract:
In blood serum of healthy persons the activity of arginase (EC 3.5.3.1) is very low, whereas in patients with myocardial infarction it increases within a few hours after the first attack of coronary pain, and returns to normal values after 3-5 days. No increase of arginase activity was observed in sera of patients with angina pectoris, coronary insufficiency or cardiac failure. Determination of arginase activity in blood serum may serve as a useful test in early differential diagnosis of myocardial infarction.
