Serum ferritin during inflammation. A study on myocardial infarction

Area of Science:

• Cardiology
• Biochemistry

Background:

• Myocardial infarction (MI) is a leading cause of mortality.
• Biomarkers for early MI detection and severity assessment are crucial.
• Ferritin, an iron-storage protein, has been explored for its role in various conditions.

Purpose of the Study:

• To investigate serum ferritin level changes in patients with acute myocardial infarction.
• To determine the kinetics and correlation of ferritin rise with infarction severity.

Main Methods:

• Serum ferritin levels were measured in 9 patients admitted with chest pain <4 hours.
• Serum levels of myoglobin, ASAT, and LDH were used to estimate infarction size.
• Temporal changes in ferritin and iron levels were monitored.

Main Results:

• A significant rise in serum ferritin was observed in 8 out of 9 MI patients.
• The ferritin rise began around 30 hours post-admission, peaking within a week.
• Ferritin levels did not significantly correlate with infarction size estimates.
• An initial rise in serum iron was unexpectedly noted within 12 hours in 7 patients.

Conclusions:

• Serum ferritin elevation is a common finding in acute myocardial infarction.
• The ferritin response in MI differs from acute infections and does not reliably indicate infarction size.
• Ferritin may serve as a potential, albeit delayed, biomarker in MI management.
