Myocardial infarction with angiographically normal coronary arteries
Annals of the Academy of Medicine, Singapore
|October 1, 1980
Summary
Acute myocardial infarction, a heart attack without blocked arteries, is rare. This case study details a patient with myocardial infarction despite clear coronary arteries, exploring potential causes.
Area of Science:
- Cardiology
- Pathophysiology
Background:
- Acute myocardial infarction (AMI) typically results from coronary artery obstruction.
- Non-obstructive myocardial infarction presents a diagnostic and therapeutic challenge.
Observation:
- A 32-year-old patient presented with documented acute inferior and anterior wall myocardial infarctions.
- Coronary arteriography performed 23 months post-infarction showed no angiographic evidence of coronary artery obstruction.
Findings:
- The case confirms the occurrence of myocardial infarction in the absence of significant coronary artery disease.
- This suggests alternative or contributing pathophysiological mechanisms beyond typical atherosclerosis.
Implications:
- Further research into non-atherosclerotic causes of myocardial infarction is warranted.
- Understanding these mechanisms may lead to improved diagnostic strategies and targeted therapies for select AMI patients.
