Antipsychotics and Associated Risk of Out-of-Hospital Cardiac Arrest

Research output: Contribution to journalJournal articleResearchpeer-review

Antipsychotic drugs have been associated with sudden cardiac death, but differences in the risk of out-of-hospital cardiac arrest (OHCA) associated with different antipsychotic drug classes are not clear. We identified all OHCA in Denmark (2001-2010). Risk of OHCA associated with antipsychotic drug use was evaluated by conditional logistic regression analysis in case-time-control models. In total, 2,205 (7.6%) of 28,947 OHCA patients received treatment with an antipsychotic drug at the time of event. Overall treatment with any antipsychotic was associated with OHCA (odds ratio [OR]= 1.53, 95% confidence interval [CI]:1.23-1.89) as was use with typical antipsychotics (OR= 1.66, CI: 1.27-2.17). By contrast, overall atypical antipsychotics drug use was not (OR= 1.29, CI: 0.90-1.85). Two individual typical antipsychotic drugs were associated with OHCA, haloperidol (OR= 2.43, CI: 1.20-4.93) and levomepromazine (OR= 2.05, CI: 1.18-3.56) as was one atypical antipsychotic, quetiapine (OR= 3.64, CI: 1.59-8.30).Clinical Pharmacology & Therapeutics (2014); Accepted article preview online 24 June 2014; doi:10.1038/clpt.2014.139.
