  Figure 1. Flow chart of verification and adjudication of all reported IHD cases. The flow chart summarises the verification and adjudication of reported IHD cases. Participants with a history of IHD at baseline were excluded, as were IHD cases reported by death registries or with inaccessible records or inconsistent disease status. 7200 IHD cases with prior IHD at baseline and 4045 IHD cases reported by death registries were excluded. 6488 reported IHD cases that were inaccessible and/or had inconsistent status were excluded. CVD, cardiovascular disease; HI, health insurance; IHD, ischaemic heart disease; MI, myocardial infarction

  Figure 2. Estimated cumulative event rates of recurrent or subsequent MI events, heart failure, stroke and all−cause mortality from 28 days after first adjudicated events of MI and IHD of any type. The plotted lines show the cumulative incidence function, starting at the date of first IHD event, separately for MI and IHD of any type and years of follow-up. Deaths from any cause were treated as competing risks. Participants experiencing an event or death within 28 days from first IHD event were excluded. Plotted points mark the cumulative incidence function at annual increments. IHD, ischaemic heart disease; MI, myocardial infarction.

  Figure 3. The 28-day and 5-year mortality rates (95% CI) for adjudication-confirmed MI and all IHD cases, by age at risk, sex, area and hospital tier. The 28-day mortality rates for adjudicated cases of MI and all IHD were estimated as proportions who died within 28 days of the index event and standardised to the age distribution (10-year age groups) of all adjudicated IHD cases. The 5-year mortality rates were estimated cumulative event rates, with participants dying within 28 days of the index event excluded. IHD, ischaemic heart disease; MI, myocardial infarction.
