Insights
Myocardial bridging, a coronary artery anomaly, can precipitate acute myocardial infarction, even in cases linked to anemia from blood donation. This case highlights an unusual presentation and management of myocardial infarction in a young man.
Area of Science:
- Cardiology
- Vascular Biology
Background:
- Myocardial bridging involves systolic compression of coronary arteries by heart muscle.
- While often benign, it can lead to myocardial ischemia, infarction, and sudden cardiac death.
Observation:
- A 33-year-old man presented with acute anteroseptal myocardial infarction post-blood donation.
- Coronary angiography revealed myocardial bridging in the left anterior descending artery.
- The patient had severe anemia, prompting a blood transfusion.
Findings:
- Primary percutaneous intervention was deferred due to myocardial bridging.
- Blood transfusion corrected severe anemia and led to clinical reperfusion.
- The patient recovered fully with no cardiac complaints at one-year follow-up.
Implications:
- Myocardial bridging can manifest as acute myocardial infarction in diverse clinical scenarios.
- Anemia-induced myocardial infarction, complicated by myocardial bridging, requires careful management.
- This case underscores the importance of considering unusual etiologies for myocardial infarction.
Background:
Systolic compression of a coronary artery by overlying myocardial tissue is termed myocardial bridging. Myocardial bridging usually has a benign prognosis, but some cases resulting in myocardial ischemia, infarction and sudden cardiac death have been reported. We are reporting a case of myocardial bridging which was complicated with acute myocardial infarction associated with inappropriate blood donation.
Case Presentation:
A 33 year-old-man was admitted to our emergency with acute anteroseptal myocardial infarction after a blood donation. The electrocardiography showed sinus rhythm and was consistent with an acute anteroseptal myocardial infarction. We decided to perform primary percutanous intervention (PCI). Myocardial bridging was observed in the mid segment of the left anterior descending coronary artery on coronary angiogram. PCI was canceled and medical follow up was decided. Blood transfusion was made because he had a deep anemia. A normal hemoglobin level and clinical reperfusion was achieved after ten hours by blood transfusion. At the one year follow up visit, our patient was healthy and had no cardiac complaints.
Conclusions:
Myocardial bridging may cause acute myocardial infarction in various clinical conditions. Although the condition in this case caused profound anemia related acute myocardial infarction, its treatment and management was unusual.
