Later Complications of MI

• Common Later Complications:

  • Chronic ventricular failure
  • Left Ventricle aneurysm
  • Late arrhythmias
  • Post-infarct angina
  • Re-infarction
  • Post-myocardial syndrome
• Common Later Complications - Left Ventricle aneurysm:

  • may occur at any stage
  • Any aneurysm whether in a vessel or cardiac chamber disturbs blood dynamics/flow patterns and predisposes to thrombus formation, as well as the risk of rupture
• Common Later Complications - Post-infarct angina:

  • anginal pain that begins within 10 days of an acute myocardial infarction, usually requires a percutaneous coronary intervention (PCI)
• Common Later Complications - Re-infarction:

  • failure to provide adequate pharmacology and / or failure to adequately modify lifestyle factors results in a subsequent MI as some undefined later date
• Common Later Complications - Post-myocardial syndrome:

  • (Dresslers syndrome)
  • occurs weeks / months following acute myocardial infarction
  • It consists of pericarditis occurring as a result of friction between the dyskinetic epicardium and the pericardium
  • Signs of post-myocardial syndrome include pain on inspiration and movement
  • Eventually an auto-immune response is triggered resulting in pleuritis and pleural effusion in addition to the pericarditis
  • Dressler’s syndrome is rare
