. Background. Use of antipsychotics has been linked with an adverse cardiovascular risk factor profile and an increased risk of dysrhythmia and sudden cardiac death. However, detailed data on the association between use of antipsychotics and development of atherosclerotic disease are limited. Objective. To examine risk of hospitalization for myocardial infarction (MI) amongst users of antipsychotics compared with non‐users. Design and subjects. A population‐based case–control study using data from hospital discharge registries in the counties of North Jutland, Viborg and Aarhus, Denmark, and the Danish Civil Registration System. We identified 21 377 cases of first‐time hospitalization for MI and 106 885 sex‐ and age‐matched non‐MI population controls in the period 1992–2004. All prescriptions for antipsychotics filled prior to the date of admission for MI were retrieved from population‐based prescription databases. We used conditional logistic regression to adjust for a wide range of covariates. Results. Current users of atypical [adjusted relative risk: 0.98, 95% confidence interval (CI): 0.88–1.09] and typical antipsychotics (adjusted relative risk: 0.99, 95% CI: 0.96–1.03) had no increased overall risk of being admitted to hospital for MI when compared with non‐users of antipsychotics. These findings were consistent in all examined subgroups. Further, we found no association between the cumulative dose of antipsychotics and the risk of hospitalization for MI. Conclusion. These findings do not support the hypothesis that use of antipsychotics and in particular atypical antipsychotics is associated with increased risk of MI.
