A patient experienced worsening angina pectoris, progressing to myocardial necrosis despite coronary artery bypass surgery. Autopsy revealed severe three-vessel coronary artery disease, highlighting the critical nature of advanced atherosclerosis.

Area of Science:

  • Cardiology
  • Pathology

Background:

  • Coronary artery disease (CAD) can progress asymptomatically.
  • Angina pectoris is a symptom of myocardial ischemia due to CAD.

Observation:

  • A 48-year-old man presented with exertional chest pain (angina pectoris).
  • Symptoms progressed to "pre-infarct" angina, followed by myocardial necrosis.
  • The patient underwent saphenous vein coronary artery bypass surgery but died postoperatively.

Findings:

  • Autopsy confirmed severe three-vessel coronary artery disease.
  • Myocardial changes consistent with global ischemia were observed.
  • The case discusses differences between subendocardial and transmural infarcts and subendocardial hemorrhage.

Implications:

  • This case underscores the severity of advanced coronary atherosclerosis.
  • It highlights the risks associated with surgical intervention in end-stage CAD.
  • Understanding infarct types and hemorrhage is crucial for diagnosis and treatment.
