Insights
Blunt cardiac injury (BCI) can lead to myocardial infarction and heart failure if misdiagnosed. Prompt diagnosis and treatment of chest trauma cardiac complications are crucial to prevent long-term heart damage.
Area of Science:
- Cardiology
- Trauma Surgery
Background:
- Blunt cardiac injury (BCI) is a recognized complication of blunt chest trauma.
- Myocardial infarction (MI) following chest trauma is rare but potentially fatal.
Observation:
- A previously healthy 38-year-old man presented with dyspnea 3 months after a chest injury.
- Initial diagnosis was delayed due to lack of physician experience with this rare presentation.
Findings:
- Coronary angiography and echocardiography confirmed myocardial infarction.
- The patient developed chronic heart failure with reduced ejection fraction at 4-year follow-up.
Implications:
- Delayed diagnosis and treatment of BCI can lead to severe cardiac complications like heart failure.
- Physicians must maintain a high index of suspicion for cardiac injury in patients with chest trauma to avoid misdiagnosis.
Rationale:
Blunt cardiac injury (BCI) is a common complication after blunt chest trauma, which can lead to mild arrhythmia, severe chamber or valvular rupture, or even death. Myocardial infarction following blunt chest trauma is a rare but fatal condition.
Patient Concerns:
A 38-year-old, previously healthy, man was admitted to our hospital with a complaint of dyspnea. He had a history of being hit in the chest by a high-speed screw while working in a factory 3 months before he was admitted to the hospital.
Diagnosis:
After performing coronary angiography and echocardiography, he was finally diagnosed with myocardial infarction.
Interventions:
He received optimized medications, including diuretics, β-blockers, and cardiac stimulants.
Outcomes:
At the 4-year follow-up, the patient was diagnosed as having chronic heart failure with a reduced ejection fraction.
Lessons:
Owing to the first doctor's lack of experience and knowledge with this case, the patient was misdiagnosed and treatment was delayed, which subsequently led to heart failure.BCI can lead to myocardial infarction if patients are misdiagnosed and treatment is delayed. Thus, surgeons and physicians should consider cardiac complications in patients with chest trauma to reduce the incidence of its misdiagnosis.

01:24Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
