Anginal pain is: constricting discomfort in the front of the chest, or in the neck, shoulders, jaw or arms precipitated by physical exertion relieved by rest or GTN within about 5 minutes. [2010, amended 2016] 1.3.3.2 Do not define typical and atypical features of anginal chest pain and non- anginal chest pain differently in men and women. [2010] 1.3.3.3 Do not define typical and atypical features of anginal chest pain and non- anginal chest pain differently in ethnic groups. [2010] 1.3.3.4 Take the following factors, which make a diagnosis of stable angina more likely, into account when estimating people's likelihood of angina: age whether the person is male cardiovascular risk factors including: a history of smoking diabetes hypertension dyslipidaemia family history of premature coronary artery disease (CAD) other cardiovascular disease history of established CAD, for example, previous MI, coronary 1.3.3.5 Unless clinical suspicion is raised based on other aspects of the history and risk factors, exclude a diagnosis of stable angina if the pain is non- anginal (see recommendation 1.3.3.1). Features which make a diagnosis of stable angina unlikely are when the chest pain is: continuous or very prolonged and/or unrelated to activity and/or brought on by breathing in and/or associated with symptoms such as dizziness, palpitations, tingling or difficulty swallowing. Consider causes of chest pain other than angina (such as gastrointestinal or musculoskeletal pain). [2010] 1.3.3.6 Consider investigating other causes of angina, such as hypertrophic cardiomyopathy, in people with typical angina-like chest pain and a low likelihood of CAD. [2010, amended 2016] 1.3.3.7 Arrange blood tests to identify conditions which exacerbate angina, such as anaemia, for all people being investigated for stable angina.
