Abstract
Objective: To investigate possible gender differences in patients with acute myocardial infarction (AMI) and without significant stenoses on coronary angiography (CAG) regarding prognosis and use of secondary preventive medication. Design: Nationwide register-based cohort study. Patients: By compiling data from Danish registries, we identified 20,800 patients hospitalized with AMI during 2005-2007. We included the 834 women and 761 men without significant stenoses on CAG who were discharged and alive after 60 days. Main outcome measures: All-cause mortality, recurrent AMI, and redeeming a prescription for a lipid-lowering drug, beta-blocker, clopidogrel, or aspirin within 60 days of discharge. Results: During follow-up, 97 women and 60 men died, resulting in a crude female/male hazard ratio (HR) of 1.51 (95% CI 1.09-2.08). After adjustment for age, time-period, and comorbidity, the gender difference was attenuated (HR 1.22, 95% CI 0.86-1.72). AMI recurrence was experienced by 28 women and 29 men with a female/male HR 0.88 (95% CI 0.52-1.48). After multivariable adjustment results were similar (HR 0.84, 95% CI 0.50-1.43). More women than men redeemed a prescription for lipid-lowering drugs with no differences in other medication. In the adjusted models lipid-lowering drugs, beta-blockers, clopidogrel, and aspirin were all redeemed equally with odds ratio (OR) 1.25 (95% CI 0.99-1.59), OR 1.10 (95% CI 0.88-1.37), OR 1.09 (95% CI 0.88-1.34), and OR 1.13 (95% CI 0.90-1.42), respectively. Conclusion: Our study shows that in a population of patients with a first admission for AMI and no significant stenoses on CAG, women share the same prospects as men regarding long-term prognosis and the extent of secondary preventive medical treatment.
