Conclusions
This large community-based nested case-control study implies that the increased mortality in elderly users of antipsychotics cannot be explained by an increased risk of ACS, as we showed that current users of antipsychotics had a 50% lower risk of being admitted to hospital for ACS, when compared with past users of antipsychotics. Further research is needed to confirm our results and to determine whether there is a cardioprotective effect or a high non-referral rate in elderly antipsychotic users with ACS.
