Ischaemic heart disease (K74, K75, K76)

Ischaemic heart disease may manifest as asymptomatic coronary atherosclerosis, as (stable) angina pectoris and / or as acute coronary syndrome (ACS). ACS comprises instable angina pectoris (IAP) or acute myocardial infarction (AMI). Angina pectoris (AP) refers to chest symptoms from myocardial ischaemia. Stable AP is characterised by chest tightness or pain, is provoked by physical exercise, emotions or cold, and disappears at rest or with sublingual nitrates within 15 minutes. In ACS, symptoms are generally more severe and rest or nitrates do not completely resolve the symptoms. In IAP, myocardial ischaemia occurs progressively at rest or at minimal physical exertion.
