Death from myocardial infarction after exercise test with normal result
Insights
Sudden cardiac death occurred after exercise testing due to acute myocardial infarction. Atherosclerotic plaque hemorrhage and clot formation caused coronary artery occlusion, likely triggered by the physical exertion.
Area of Science:
- Cardiology
- Pathology
Background:
- Acute myocardial infarction can lead to sudden cardiac death.
- Exercise testing is a common diagnostic tool in cardiology.
Abstract:
Death from acute myocardial infarction immediately followed a submaximal exercise test with a normal result in a 56-year-old man. Hemorrhage into an intimal atherosclerotic plaque with superimposed, intraluminal clot formation was the cause of coronary artery occlusion. It is probable that the exercise precipitated an intramural capillary rupture and intimal hemorrhage or caused further hemorrhage into a preexisting intimal hematoma. The resulting luminal narrowing and intimal rupture with superimposed clot formation caused coronary artery occlusion.
