Summary

An elderly female presented with altered consciousness and an unusual myocardial infarction (MI). Despite a history of stroke, she experienced a large, transmural anterior wall MI, leading to cardiogenic shock and requiring advanced cardiac assessment.

Area of Science:

  • Cardiology
  • Emergency Medicine

Background:

  • Altered mental status in elderly patients without trauma presents diagnostic challenges.
  • A history of cerebrovascular accident (CVA) necessitates consideration of embolic events.

Observation:

  • The patient presented with decreased consciousness, vomiting, and hypotension, an atypical presentation of myocardial infarction (MI) in elderly females.
  • Diagnostic imaging revealed a large, akinetic anterior wall, indicative of a transmural myocardial infarction.
  • The patient was in profound cardiogenic shock due to left ventricular dysfunction.

Findings:

  • The patient had a large transmural anterior wall MI, likely due to left anterior descending artery (LAD) occlusion.
  • Cardiogenic shock resulted from the infarcted left ventricle's inability to maintain cardiac output.
  • Thrombolytic therapy was contraindicated due to the patient's recent stroke history.

Implications:

  • This case highlights the importance of recognizing atypical MI presentations in the elderly.
  • Prompt diagnosis and management of cardiogenic shock are critical for patient outcomes.
  • Familiarity with cardiac anatomy, physiology, and emergency interventions is essential for healthcare providers.
