ECG Changes and High Sensitivity Troponin I in Acute Cholecystitis

Area of Science:

• Cardiology
• Gastroenterology
• Emergency Medicine

Background:

• Abdominal pain is a frequent emergency department (ED) presentation with diverse causes, including acute coronary syndrome.
• Elevated high-sensitivity troponin I (hs-TnI), a cardiac biomarker, can occur in noncardiac conditions like acute cholecystitis.
• Conventional troponin assays may lack sensitivity in diagnosing subtle myocardial injury.

Purpose of the Study:

• To highlight the utility of hs-TnI in diagnosing acute cholecystitis.
• To demonstrate the advantages of hs-TnI over conventional troponin assays, particularly in patients with abnormal ECGs.
• To emphasize hs-TnI's role in identifying myocardial injury secondary to noncardiac conditions.

Main Methods:

• Case study analysis.
• Review of hs-TnI performance in patients presenting with abdominal pain and potential cardiac involvement.
• Comparison of hs-TnI with conventional troponin testing and electrocardiogram (ECG) findings.

Main Results:

• hs-TnI demonstrated superior sensitivity in detecting subtle myocardial injuries.
• The study identified hs-TnI elevation in a case of acute cholecystitis, mimicking cardiac events.
• hs-TnI proved advantageous in patients with abnormal ECGs, aiding differential diagnosis.

Conclusions:

• hs-TnI integration enhances diagnostic accuracy for acute cholecystitis in the ED.
• Advanced practice registered nurses can utilize hs-TnI for improved risk stratification and patient management.
• This biomarker facilitates earlier and more effective diagnosis and treatment of acute cholecystitis.
