For men older than 70 years with atypical or typical symptoms, assume an estimate >90%. For women older than 70 years, assume an estimate of 61–90%, except women at high risk and with typical symptoms, where a risk of >90% should be assumed. Values are per cent of people at each mid-decade age with significant coronary artery disease (CAD).5 High = high risk = diabetes, smoking, and hyperlipidaemia (total cholesterol >6.47 mmol/litre). Low = Low risk = none of these three. The area in bold represents people with symptoms of non-anginal chest pain, who would not be investigated for stable angina routinely. Note: these results are likely to overestimate CAD in primary care populations. If there are resting ECG ST-T changes or Q waves, the likelihood of CAD is higher in each cell of the table
