    Notes to Table 1.1
      1. In Table 1.1, 'not applicable' means the criterion is not applicable to the specified level of impairment.
      2. Pathology – column 3.
        (i)        Coronary artery disease:
           + either <50% stenosis in one or more coronary arteries, or single vessel disease >50% stenosis (except proximal left anterior descending (LAD) and left main coronary artery (LMCA)
           ++ either >50% stenosis in two vessels, or >50% stenosis in proximal LAD, or <50% stenosis in LMCA
           +++ either >50% stenosis in 3 vessels, or LMCA >50% stenosis, or severe diffuse end organ disease.
        (ii)      Ischaemic left ventricular dysfunction:
           + left ventricular ejection fraction (LVEF) 40-50%
           ++ LVEF 30-40%
           +++ either LVEF <30%, or LV aneurysm.
        (iii)     Myocardial infarction (MI):
           + no previous MI
           ++ previous possible MI (equivocal changes in ECG/cardiac enzymes)
           +++ previous definite MI (unequivocal changes in ECG/cardiac enzymes: typical evolution of ST/T segments, or development of significant Q waves, or enzyme rise >3 times upper limit of normal).
        (iv)     Arrhythmias:
           Assessed under Table 1.3: Arrhythmias.
3.     Drug therapy (continuous) – column 4:
         + one or two drugs
         ++ three or four drugs
         +++ five or more drugs.
4.     Intervention – column 5:
'PTCA' means percutaneous transluminal coronary angioplasty and/or stenting.
'CABG' means coronary artery bypass grafting.
'Tx' means heart transplant.
