*Model 1: unadjusted.
†Model 2: adjustment for age group.
‡Model 3: model 2+adjustment for year of admission, prior revascularisation, cardiac arrhythmias, heart failure, pulmonary oedema, cardiogenic shock, cancer, COPD, cerebrovascular disease, diabetes with complications, acute and chronic renal failure and distance to nearest hospital with cardiac catheterisation facilities.
§Model 4: model 3+adjustment for use of antihypertensive medication, statin or other lipid-lowering drug, β-blockers, aspirin, and loop-diuretics prior to index admission.
¶Model 5: model 4+adjustment for income, level of education and living alone (n=48 609).
**Log-likelihood ratio test p value for interaction between sex and year of admission using model 5.
COPD, chronic obstructive pulmonary disease; DCA, diagnostic coronary angiography.
