Aims
Ischaemic heart disease persists as the leading cause of death in both men and women in most countries and sex disparities, defined as differences in health outcomes and their determinants, may be relevant. We examined sex disparities in presenting characteristics, treatment and all-cause mortality in patients hospitalized with myocardial infarction (MI) or angina.
Methods and results
We conducted a cohort study of all patients admitted with MI or angina (01 October 2013 to 30 June 2016) from a secondary care acute coronary syndrome e-Registry in NHS Scotland linked with national registers of community drug dispensation and mortality data. A total of 7878 patients hospitalized for MI or angina were prospectively included; 3161 (40%) were women. Women were older, more deprived, had a greater burden of comorbidity, were more often treated with guideline-recommended therapy preadmission and less frequently received immediate invasive management. Men were more likely to receive coronary angiography [adjusted odds ratio (OR) 1.52, confidence interval (CI) 1.37–1.68] and percutaneous coronary intervention (adjusted OR 1.68, CI 1.52–1.86). Women were less comprehensively treated with evidence-based therapies post-MI. Women had worse crude survival, primarily those with ST-elevation myocardial infarction (14.3% vs. 8.0% at 1 year, P < 0.001), but this finding was explained by differences in baseline factors. Men with non-ST-elevation myocardial infarction had a higher risk of all-cause death at 30 days [adjusted hazard ratio (HR) 1.72, CI 1.16–2.56] and 1 year (adjusted HR 1.38, CI 1.12–1.69).
Conclusion
After taking account of baseline risk factors, sex differences in treatment pathway, use of invasive management, and secondary prevention therapies indicate disparities in guideline-directed management of women hospitalized with MI or angina.
