** within the same broad diagnostic group (e.g. for ischaemic heart disease, a general practice record of myocardial infarction for a HES record of other ischaemic heart disease or vice versa; for cerebrovascular disease, a general practice record of stroke or other cerebrovascular disorders for a HES record of transient ischaemic attack or vice versa; for venous thromboembolism, a general practice record of pulmonary embolism for a HES record of venous thrombosis or vice versa).
