What are the Risks Associated with Myocardial Contusion?


A myocardial contusion, also called a cardiac contusion, happens when your heart muscle gets bruised. This often occurs due to car accidents or falls. The treatment you need will depend on any problems that arise from this injury. How quickly you recover depends on how bad the bruise is, but most people get better completely.

What is a myocardial infarction?

A myocardial contusion, also known as a bruised heart muscle due to a chest contusion, happens when your chest is hit hard without breaking the skin. This is often caused by a car accident.

The injury can be mild, with only a small bruise that doesn’t cause issues, or it can be more serious, affecting how well your heart works.

What causes a myocardial infarction?

When something hits your chest really hard, it can cause a myocardial contusion, which is like a bruise on your heart. Your chest bones usually protect your heart, so it needs a strong force to get hurt. Some common reasons for a blunt cardiac injury are:

  • Falling from a high place, like more than 20 feet
  • Car accidents
  • Pushing hard on the chest during CPR
  • Being hit by a car
  • Sports accidents
  • Getting squeezed really hard

Who’s likely to be affected by myocardial infarction?

Anyone can have a myocardial contusion. Here are some examples:

  • A teenager or young adult who gets hurt doing an extreme sport.
  • A middle-aged person who falls while working high up on a construction site.
  • An elderly person in their 80s gets a chest injury in a car crash.

Symptoms of a Myocardial Infarction

If your heart bruise is not serious, you might only notice your heart beating fast. But if it’s really bad, it might feel like you’re having a heart attack.

Symptoms of a chest contusion leading to heart bruise can include:

  • Feeling dizzy.
  • Having a stomachache.
  • Having pain in your chest or ribs.
  • Hurting and bruising near your breastbone or ribs
  • Other injuries near your chest
  • Feeling like you can’t catch your breath
  • Skin feeling sweaty, cool, or bluish
  • Having very low blood pressure, which can be dangerous
  • Your heart beating in a strange way
  • Feeling your heart thumping, racing, or beating irregularly
  • Going into shock

Risks Associated with a Myocardial Infarction

Sometimes, when the chest gets hit hard, a rare type of injury called commotio cordis can happen. It doesn’t directly hurt the heart muscle, but it messes up the heart’s rhythm. This sudden change in rhythm can lead to the heart suddenly stopping in an otherwise healthy state.

Commotio cordis is a big reason why young athletes might suddenly die. It mostly happens to kids. This could be because kids have thinner chests, or they often play sports where this kind of injury can happen. If someone gets commotio cordis, it’s super important to use a machine called an automated external defibrillator (AED) right away.

To lower the risk of commotio cordis and make it more likely for someone to survive if it happens, here are some tips:

  • Coaches and grown-ups should know how to spot commotio cordis and do CPR.
  • Every place where sports happen should have an AED that’s easy to get to.
  • If it’s possible, there should be a doctor or nurse around during sports events who can help if there’s an emergency.

Diagnosing Myocardial Contusion

Finding out if you have a cardiac contusion can be tricky. Even if your chest doesn’t look hurt on the outside, you could still have a serious case of it.

Your doctor will check you over and run some tests.

If you do have a heart bruise, they might see:

  • Signs that your ribs are broken, like feeling a crunching sensation in your chest.
  • Low blood pressure.
  • Your heart is beating strangely.
  • Breathing really fast.
  • Scrapes or bruises on your chest.

Treatment Options and Complications of Myocardial Infarction

When you have a heart bruise, doctors don’t have one specific way to treat it. But they’ll keep a close eye on you and handle any problems that come up.

If you’re in the emergency room, you might get:

  • Oxygen to help you breathe.
  • Fluids through a tube in your arm or hand.
  • Medicine for a weird heart rate, low blood pressure, or pain.
  • A temporary pacemaker.
  • A tube in your chest to drain away extra blood near your heart.

If a blood test shows that your heart muscle is damaged, the doctor might keep you in the hospital. They’ll keep checking your blood to see how things are going.

Having a heart bruise can lead to some serious issues, like:

  • Your heart not working right (heart failure).
  • Your heart muscle breaking.
  • Fluid building up around your heart (cardiac tamponade).
  • Your heart suddenly not pumping enough blood (cardiogenic shock).
  • Weird heartbeats.
  • Sudden death with no warning.

Medications and Other Treatments

Everyone’s treatment and medicine needs can vary, depending on the issues they’re facing. Your doctor might suggest:

  • Medicines to help your heart pump better if you have heart failure.
  • Getting rid of extra fluid around your heart with something called pericardiocentesis if you have pressure from cardiac tamponade.
  • Medicine or a pacemaker to fix weird heartbeats.
  • Medicine or temporary tools to help your heart pump better if you have cardiogenic shock.
  • Surgery to fix a torn heart muscle (but this doesn’t happen very often).

Knowing More About Myocardial Infarction for Prevention

Let’s make sure we’re all aware of the signs and risks associated with heart bruises. Whether it’s from a fall, a sports injury, or a car accident, anyone could be affected. Look out for symptoms like chest pain, trouble breathing, or feeling faint. If you or someone you know experiences these, don’t hesitate to seek medical help immediately. Remember, knowing the signs and getting timely treatment can make all the difference in preventing serious complications.
