Cardiac Contusion After an Accident
A cardiac contusion can be a frightening and serious injury caused by a motor vehicle accident. Chest trauma can temporarily, and in some cases, permanently damage the myocardial tissue. Such an injury can lead to a traumatic myocardial infarction, commonly known as a heart attack.
If you are experiencing chest pain after a serious car accident or another traumatic incident, a cardiac contusion should be medically ruled out. It is important to see a physician immediately. Following urgent medical care, you should also contact an experienced injury lawyer who, if appropriate, can help you initiate a claim for monetary compensation.

A cardiac contusion or “myocardial contusion” is a bruise to part of the heart muscle that results from blunt trauma or a deceleration injury to the chest wall. This usually involves a portion of the right ventricle of the heart, but other parts of the heart can be affected. The extent of the contusion can be minor or major.
Often, a myocardial contusion is associated with a fracture of the sternum or a fracture of one or more ribs. While a cardiac contusion is dangerous enough, other serious and potentially fatal complications could be present as well, such as:
- Aortic rupture
- Rupture of the myocardium
- Ruptured septum
- Valve injury
- Myocardial infarction
- Dysfunction of the heart
- Heart arrhythmia
Fortunately, a cardiac contusion caused by a motor vehicle accident is a rare injury. However, when they do occur, they can be serious. Following this type of injury, the two most common sequelae are arrhythmia and hypotension. It is difficult to diagnose a cardiac contusion because the bruised tissue cannot be easily visualized. In at least one study, cardiac contusions were present in 14 percent of patients who died from blunt trauma, such as that sustained in a car accident.Causes of Cardiac Contusion
The major cause of cardiac contusion is blunt trauma to the chest. In most cases, it requires a significant impact to the chest to bruise the heart muscle.
The most common causes of the kind of blunt trauma that would result in a myocardial contusion include:
- Automobile accidents. The classic mechanism of injury involves the driver of the vehicle striking their chest on the steering wheel.
- A patient who was subject to cardiopulmonary resuscitation or CPR.
- Falling from a great height, such as 20 feet above the ground.
It is not possible to visualize the myocardium at the time of an injury, so a doctor will rely on signs and symptoms to determine whether a cardiac contusion may have occurred. The following are signs and symptoms associated with a cardiac contusion:
- Bruising of the anterior chest wall
- Tenderness and pain in the sternum or top of the ribcage
- Arrhythmia or racing heart
- Pain that worsens when taking a deep breath
- Lightheadedness/feeling faint
- Shortness of breath
- Nausea or vomiting
- Coughing up blood
If signs and symptoms of a cardiac contusion exist, the physician may order additional evaluation to assess serious cardiac damage.Auto Accident Risk Factors for Cardiac Contusion
Risk factors for a cardiac contusion following an auto accident include:
- The patient was not wearing a seatbelt
- Deployment of the frontal airbag
- High-speed crashes
- The patient was a pedestrian hit by a car
Reaching a diagnosis of cardiac contusion diagnosis is complex and usually based on signs and symptoms only. This is because the injury can only be definitively diagnosed during surgery or autopsy, though there are lab tests that may indicate the presence of cardiac injury.
Electrocardiography or ECG studies have been commonly used by doctors who may be considering the presence of a myocardial contusion. Through research, it has been found that an abnormal ECG at the time of admission to the emergency room often correlated to cardiac complications of the trauma. Another test called transthoracic echocardiography can also be part of the diagnostic process.
When arrhythmias are present, this is a potential sign of traumatic cardiac injury. Still, again, there is no real diagnostic test that surely identifies the presence or absence of cardiac contusion following a car accident.Treatment of Cardiac Contusion After a Car Accident
Treatment for a cardiac contusion is similar to the conservative approach following a minor heart attack. The patient is usually hospitalized and placed on cardiac monitoring for a period of up to 48 hours. One study revealed that nearly 95 percent of all life-threatening cardiac arrhythmias or acute cardiac failures happened within 24-48 hours after the trauma.
Other potential treatment options include:
- IV catheter
- Pain medication
- Blood pressure medication
- Arrhythmia medication
- Oxygen therapy
- Placement of a temporary pacemaker
- Drainage of any bleeding areas around the heart
- Surgery to fix damaged blood vessels in the chest
- Repeat ECGs
Hospital release may occur after 48 hours if the patient is hemodynamically stable with no evidence of cardiac arrhythmia, but follow-up evaluations are advised.Complications of Cardiac Contusion
If the cardiac contusion is mild, the patient may fully recover after a few weeks. There are, however, serious complications that can occur after this injury.
Some of the potential complications include:
- Cardiac arrhythmia
- Biventricular failure
- Aortic rupture
- Cardiac rupture
