Myocardial infarction with patent coronary arteries
Insights
Sudden cardiac death occurred 6 days after acute myocardial infarction, possibly due to early coronary thrombus lysis. This case suggests rapid clot resolution may precede fatal events in some patients.
Area of Science:
- Cardiovascular Medicine
- Pathology
- Clinical Cardiology
Background:
- Acute anterior wall myocardial infarction (MI) diagnosis confirmed via clinical, ECG, and enzymatic markers.
- Patient presented with ST-elevation MI, a critical condition requiring immediate intervention.
Observation:
- ECG normalized by day 5 post-MI.
- Sudden cardiac death occurred on day 6 post-MI.
- Autopsy revealed transmural anterior MI with mural thrombus and a renal artery thrombus.
Findings:
- Coronary arteries showed only minor arteriosclerotic changes.
- A mural thrombus was present in the infarcted anterior wall.
- A fresh thrombus was found in the left renal artery.
Implications:
- The study hypothesizes early coronary thrombus lysis as the cause of MI.
- This case presents evidence of thrombus lysis occurring as early as 6 days post-MI.
- Such rapid thrombus resolution has not been previously documented and warrants further investigation in MI pathogenesis and outcomes.
Abstract:
A 62-year-old patient suffered an acute anterior wall infarction as documented by clinical, electrocardiographic and enzymatic evidence. His ECG returned to a near normal pattern on the 5th day. The next day the patient died suddenly. Post mortem examination revealed a transmural anterior infarction with a mural thrombus, and a fresh thrombus in the left renal artery, but the coronary arteries were patient with only slight arteriosclerotic changes. We assume that a coronary thrombus might have been the cause of the infarction, with subsequent lysis. Such early lysis (6 days after the infarction) has not yet been demonstrated in earlier reports.
