OBJECTIVE
To investigate the association between acute myocardial infarction (AMI) and recent exposure to antipsychotic agents in people with serious mental illness (SMI), and modifying influences.
METHODS
A case-crossover design was applied using the Taiwan National Health Insurance Research Database (NHIRD) to compare the exposure frequency of antipsychotic agents within individuals of schizophrenia or bipolar disorder between 60-day case and control periods prior to their first AMI episode during 1996-2007.
RESULTS
A sample of 834 patients with incident AMI was analysed. AMI was significantly associated with more recent antipsychotic exposure in schizophrenia after adjustment (OR 1.87, 95% confidence interval 1.15-3.03) bipolar disorder (OR 1.06, 0.51-2.21). This association in schizophrenia was significantly stronger in men and in patients without previous diagnoses of cardiovascular risk factors.
CONCLUSIONS
These findings are consistent with a short-term risk effect of antipsychotic exposure on risk of AMI and identify potentially vulnerable groups. Further research is required to clarify underlying biological mechanisms.
