The relationship between gender and mortality was examined for the population as a whole and for stratified groups depending on the type of procedures used (diagnostic coronary catheterisation and\/or percutaneous transluminal coronary angioplasty).

There were more deaths among older patients with acute myocardial infarction and greater co-morbidity. Lower mortality was shown in patients undergoing diagnostic catheterisation and\/or PTCA. After adjusting for age, diagnosis and co-morbidity, mortality affected women more than men in the overall population (OR 1.14, 95% CI: 1.06\u20131.22) and in the subgroup of patients where no procedure was performed (OR 1.16, 95% CI: 1.07\u20131.24).
