What is cardiac contusion?

Myocardial contusion is a bruise of the heart muscle. The interior of the heart is composed of valves, chambers, and associated vessels. The external structures of the heart include the ventricles, atria, arteries and veins. Arteries carry blood away from the heart while veins carry blood into the heart.

How serious is a cardiac contusion?

How is cardiac contusion diagnosed?

Cardiac contusion is an infrequent but occasionally serious complication of deceleration injury. According to ATLS teaching, the true diagnosis of contusion can only be established by direct inspection of the myocardium. The clinically important sequelae of myocardial contusion are hypotension and arrhythmia.

Can myocardial contusion cause death?

A myocardial contusion refers to a bruise of the cardiac muscle, the severity of which can vary depending on the severity of the injury and when the injury occurs. It is a major cause of rapid death which happens after blunt chest trauma and should be suspected at triage in the emergency department.

Which type of ECG changes is most commonly seen with myocardial contusion?

Patients with suspected blunt cardiac injury should have an ECG. Various nonspecific abnormalities are possible in contusion: The most common is sinus tachycardia. Continuous ECG monitoring for 24 to 48 hours is recommended when abnormalities are found.

Can your heart fall out place?

Can chest trauma elevate troponin?

Interestingly, evidence about the clinical usefulness of cardiac troponins for identifying cardiac involvement after chest trauma is limited. Ferjani et al. measured cardiac troponin T (cTnT) in 128 patients who suffered chest trauma, and found that elevated values of this biomarker were present in 31% of cases (25).

Why is troponin elevated?

When heart muscles become damaged, troponin is sent into the bloodstream. As heart damage increases, greater amounts of troponin are released in the blood. High levels of troponin in the blood may mean you are having or recently had a heart attack. A heart attack happens when blood flow to the heart gets blocked.
