Although an increase in the myocardial oxygen demand or a decrease in the oxygen-carrying capacity of the blood may cause ischaemic heart disease, nevertheless in over 90% of cases the cause is coronary artery disease.

  • atherosclerosis of the coronary arteries
  • platelet aggregation
  • coronary vasospasm
  • non-atherosclerotic coronary artery disease
  • haemodynamic derangements
