Beau's Lines After Cardiac Arrest

Area of Science:

• Cardiology
• Critical Care Medicine
• Neurology

Background:

• A 34-year-old male with uncontrolled hypertension experienced ventricular fibrillation cardiac arrest due to left anterior descending artery occlusion.
• The patient required extensive defibrillation (over 10 times) for return of spontaneous circulation.
• Initial management included therapeutic hypothermia and percutaneous coronary intervention with a bare metal stent.

Purpose of the Study:

• To describe the complex post-cardiac arrest course of a young patient with significant medical comorbidities.
• To illustrate the management challenges including cardiogenic shock, respiratory failure, and neurological complications.
• To document the patient's recovery and subsequent presentation with chest pain and Beau's lines.

Main Methods:

• Intensive care unit management including mechanical ventilation and tracheostomy.
• Treatment of methicillin-resistant Staphylococcus aureus (MRSA) tracheobronchitis.
• Neurological monitoring and management of delirium.
• Cardiac workup including rule-out myocardial infarction.

Main Results:

• The patient experienced prolonged ventilator dependence, cardiogenic shock, and delirium.
• Significant neurological recovery occurred after 34 days, leading to discharge to rehabilitation.
• A later presentation with chest pain revealed Beau's lines, with cardiac workup being negative.

Conclusions:

• Survivors of cardiac arrest can experience prolonged and complex recovery trajectories.
• Recognition of Beau's lines in the context of prior cardiac events warrants careful evaluation.
• Multidisciplinary care is essential for managing post-cardiac arrest complications and ensuring long-term patient outcomes.
