Alternative Names

Causes

The most common causes are:

Symptoms

A severe myocardial contusion may lead to signs and symptoms of a heart attack.

Symptoms can include:

  • Pain in the front of the ribs or breastbone
  • Feeling that your heart is racing
  • Light-headedness
  • Nausea or vomiting
  • Shortness of breath
  • Weakness

Exams and Tests

The doctor or nurse will perform a physical exam. This may show:

  • Bruise or scrapes on the chest wall
  • Crunching sensation when touching the skin if there are rib fractures and puncture of the lung
  • Fast heartbeat
  • Irregular heartbeat
  • Low blood pressure
  • Rapid or shallow breathing
  • Tenderness to the touch
  • Abnormal chest wall movement from rib fractures

Tests may include:

These tests may show:

  • Problems with the heart wall and the ability for the heart to contract
  • Fluid or blood in the thin sac surrounding the heart (pericardium)
  • Rib fractures, lung or blood vessel injury
  • Problem with the heart's electrical signaling (such as a bundle branch block or other heart block)
  • Fast heart beat starting at the sinus node of the heart (sinus tachycardia )
  • Abnormal heart beat starting in the ventricles or lower chambers of the heart (ventricular dysrhythmia)

Treatment

In most cases, you will be closely monitored for at least 24 hours. An electrocardiogram (ECG) will be done continually to check your heart function.

Emergency room treatment may include:

  • Catheter placement through a vein (IV)
  • Medications to relieve pain, heart rate disturbances, or low blood pressure
  • Pacemaker (temporary, may be permanent later)
  • Oxygen

Other therapies may be used to treat a heart injury, include:

  • Chest tube placement
  • Draining blood from around the heart
  • Surgery to repair blood vessels in the chest

Outlook (Prognosis)

People with a mild myocardial contusion will recover completely most of the time.

Serious heart injuries can increase your risk for heart failure or heart rhythm problems.

Prevention

The following safety tips may help prevent a heart bruise:

  • Wear a seat belt when driving.
  • Choose a car with air bags.
  • Take steps to ensure safety when working at heights.
