75 Steps for assessment are as follows.
| Step 1 | Using Figure 1-B: Symptomatic level of activity in METS according to age and gender, assess the symptomatic level of activity in METS according to age and gender. Figure 1-B may be used to assess conditions affecting left ventricular function (LVF) (including ischaemic heart disease, rheumatic heart disease, and hypertension). | | Step 2 | Using Table 1.1: Coronary artery disease, refer to any one of pathology (column 3), drug therapy (column 4), or intervention (column 5), to identify the degree of impairment within the range of impairments for that symptomatic level of activity. |
76 Figure 1-B: Symptomatic level of activity in METS according to age and gender may be used for the assessment of symptomatic impairment caused by ischaemic heart disease, hypertension, cardiomyopathy, or rheumatic heart disease.
