Abstract
Background
There is an increasing clinical focus on chronic coronary disease (CCD), yet population-level data on outcomes in CCD patients are limited. Our aim was to describe characteristics of people hospitalised with CCD and measure the short and long-term risk of cardiovascular outcomes by sex.
Method
We used state-wide linked hospitalisation/mortality data to identify CCD patients based on first (index) hospitalisation for stable angina (SA; ICD-10-AM I20.1–I20.9) or chronic ischaemic heart disease (IHD; I25) in 2002–2017. Kaplan-Meier survival analyses were used to estimate risk of acute coronary syndrome (ACS) and CVD death during 15-years follow-up from the linked dataset.
Results
There were 32,696 index SA (38% female) and 29,365 index chronic IHD (27% female) cases, with overall mean age of 66 years in men and 69 years in women in both groups. Men admitted with SA were more likely to receive angiography+/-revascularisation compared to women (66% vs 50% respectively, p<0.0001); but there was no difference between men and women for chronic IHD admissions (94% men, 91% women). One- and 15-year risk of ACS was greater in SA than chronic IHD patients, with minimal difference by sex (Table). Risk of CVD mortality was 1.4% at 1-year in SA and chronic IHD patients, increasing to 13.7% in men and 14.5% women at 15 years.
Conclusion
There is a high short- and long-term risk of ACS or CVD death after index CCD hospitalisation irrespective of sex, indicating need for improved clinical management and secondary prevention of CCD in both sexes.
