  1. ORs for a pathologic ST-T segment in the resting ECG, angina according to the patient’s subjective assessment, and exertional chest pain, were adjusted for age, systolic blood pressure, dyslipidaemia, previous cardiovascular events, and male sex. OR: odds ratio. CI: confidence interval. ECG: electrocardiogram. TIA: transitory ischaemic attack. Cardiovascular event: myocardial infarction, revascularization, stroke, or TIA. Positive exercise test: angina symptoms and depression of ST segment >0.1 mV during the test. Non-conclusive test: angina or ST depression.
