This section provides the predictive HEART score for a 6-week risk of MACE.

MACEs are defined as the following:

  • Acute myocardial infarction (MI)
  • Percutaneous coronary intervention (PCI)
  • Coronary artery bypass graft (CABG)
  • Coronary angiography revealing procedurally correctable stenosis managed conservatively
  • Death due to any cause

The following are MACE risk factors: 

  • Hypertension
  • Hypercholesterolemia
  • Diabetes mellitus
  • Obesity (body max index > 30 kg/m2)
  • Smoking (current, or smoking cessation < 1 month)
  • Positive family history for coronary artery disease
  • Atherosclerotic disease
  • Prior MI, PCI, CABG, cerebrovascular accident/transient ischaemic attack or peripheral artery disease

The following are the score levels for MACE:

  • 0 – 3: low risk; 1.7% found to have MACE
  • 4 – 6: moderate risk; 16.6% found to have MACE
  • 7 – 10: high risk; 50.1% found to have MACE
