Myocardial contusion in blunt chest trauma: a ten-year review
Insights
Myocardial contusion, a heart injury from chest trauma, affects 17% of patients. Early diagnosis is crucial as 83% experience cardiovascular complications, and awareness is needed to prevent severe outcomes.
Area of Science:
- Cardiology
- Trauma Surgery
- Critical Care Medicine
Background:
- Major chest injuries can lead to myocardial contusion, a cardiac injury.
- The incidence and clinical impact of myocardial contusion in trauma patients are not fully understood.
Purpose of the Study:
- To determine the incidence, clinical features, and outcomes of myocardial contusion in patients with major chest injuries.
Main Methods:
- A retrospective review of 169 patients admitted to an Intensive Therapy Unit (ITU) with major chest injury was conducted.
- Data on diagnosis, clinical presentation, complications, and mortality were analyzed.
Main Results:
- Myocardial contusion was diagnosed in 29 (17%) of the patients.
- Of those with myocardial contusion, 24 (83%) developed significant cardiovascular complications.
- Five patients died directly from the injury, and diagnosis was delayed in some, with six identified only at necropsy.
Conclusions:
- Myocardial contusion is a significant complication of major chest trauma.
- Increased awareness is necessary for earlier diagnosis and improved management to prevent complications and reduce mortality.
Abstract:
A retrospective review was undertaken of 169 patients admitted to an Intensive Therapy Unit with a major chest injury to determine the incidence, clinical features and outcome of patients with myocardial contusion. This injury occurred in 29 (17%) patients, of whom 24 (83%) had significant cardiovascular complications and five died as a direct result of the injury. The interval between injury and diagnosis was 3.2 +/- 2.3 days (mean +/- SD) from injury and in six patients the diagnosis was made only at necropsy. Increased awareness of myocardial contusion is required for earlier diagnosis and prevention of complications.
