Background

Formerly Known as “Cardiac Contusion”

Definition: Cardiac Injury Caused by Blunt Force Trauma to the Chest

Causes

  • Motor Vehicle Crash (MVC) – Most Common (50%)
  • Falls
  • Blast Injury
  • Assault
  • Any Other Blunt Mechanism

Most Common Symptoms: Chest Pain and Shortness of Breath

Complications

  • Arrhythmia – Most Common Complication
    • Sinus Tachycardia is the Most Common Arrhythmia
    • Often See PAC’s or PVC’s
  • Ventricular Rupture
  • Valve Disruption (Aortic Most Common)
  • Pericardial Effusion
  • Cardiac Tamponade
  • Coronary Artery Injury
  • Myocardial Ischemia
  • Constrictive Pericarditis

Sternal Fracture is Not Predictive of Blunt Cardiac Injury (3.6% Incidence)

Screening

Initial Screen: EKG

  • If Stable and EKG Normal: Troponin
  • If Unstable or EKG Abnormal: Echocardiogram and Telemetry
    • Transesophageal Echo (TEE) May Be Preferred Over Transthoracic Echo (TTE) if Available

Normal ECG and Troponin Essentially Rules Out BCI

Screening with No Benefit: CK-MB, CPK, and Nuclear Imaging

Management

Primary Treatment

  • Mostly Supportive Management
  • Monitor with Telemetry in the ICU
  • Cardiology Consultation

Adjunctive Measures

  • Fluid Resuscitation
  • Vasopressor Support and Inotropes
  • Intra-Aortic Balloon Pump (IABP)
  • Myocardial Infarction May Require Coronary Angiography
  • Structural Injury May Require Surgical Intervention
