Antipsychotics and associated risk of out-of-hospital cardiac arrest
Clinical pharmacology and therapeutics, 2014
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 OHCAs in Denmark (2001-2010). The 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 the event. Overall, treatment with any antipsychotic drug 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 antipsychotic drug use was not (OR = 1.29, CI: 0.90-1.85). Two individual typical antipsychotic drugs, haloperidol (OR = 2.43, CI: 1.20-4.93) and levomepromazine (OR = 2.05, CI: 1.18-3.56), were associated with OHCA, as was one atypical antipsyc...
Sudden cardiac death and antipsychotics. Part 2: Monitoring and prevention
Advances in Psychiatric Treatment, 2006
Available evidence does not yet allow accurate comparison of the quantitative risk of serious cardiovascular side-effects or sudden cardiac death for all antipsychotics, not least because several agents have not been examined in sufficient detail. Nevertheless, an elevated risk of serious adverse Abstract Cardiac safety of antipsychotic drugs continues to be a concern for both typical and atypical antipsychotics.
Antipsychotics and the Risk of Mortality or Cardiopulmonary Arrest in Hospitalized Adults
Journal of the American Geriatrics Society, 2019
OBJECTIVESPrior studies in outpatient and long‐term care settings demonstrated increased risk for sudden death with typical and atypical antipsychotics. To date, no studies have investigated this association in a general hospitalized population. We sought to evaluate the risk of death or nonfatal cardiopulmonary arrest in hospitalized adults exposed to antipsychotics.DESIGNRetrospective cohort study.SETTINGLarge academic medical center in Boston, Massachusetts.PARTICIPANTSAll hospitalizations between 2010 and 2016 were eligible for inclusion. We excluded those admitted directly to the intensive care unit (ICU), obstetric and gynecologic or psychiatric services, or with a diagnosis of a psychotic disorder.INTERVENTIONTypical and atypical antipsychotic administration, defined by pharmacy charges.MEASUREMENTSThe primary outcome was death or nonfatal cardiopulmonary arrest during hospitalization (composite).RESULTSOf 150 948 hospitalizations in our cohort, there were 691 total events (5...
Antipsychotic Polypharmacy-Related Cardiovascular Morbidity and Mortality: A Comprehensive Review
Neurology International
Schizophrenia is a psychotic disorder that exists at the more extreme end of a spectrum of diseases, and significantly affects daily functioning. Cardiovascular adverse effects of antipsychotic medications are well known, and include changes in blood pressure and arrhythmias. Sudden cardiac death is the leading cause of death worldwide, and antipsychotic medications are associated with numerous cardiac side effects. A possible link exists between antipsychotic medications and sudden cardiac death. Common prescribing patterns that may influence cardiovascular events include the use of multiple antipsychotics and/or additional drugs commonly prescribed to patients on antipsychotics. The results of this review reflect an association between antipsychotic drugs and increased risk of ventricular arrhythmias and sudden cardiac death by iatrogenic prolongation of the QTc interval. QTc prolongation and sudden cardiac death exist in patients taking antipsychotic monotherapy. The risk increas...

Objective To examine the rates of cardiac arrest and ventricular arrhythmia in patients with treated schizophrenia and in non-schizophrenic controls. Design Cohort study of outpatients using administrative data. Setting 3 US Medicaid programmes. Participants Patients with schizophrenia treated with clozapine, haloperidol, risperidone, or thioridazine; a control group of patients with glaucoma; and a control group of patients with psoriasis. Main outcome measure Diagnosis of cardiac arrest or ventricular arrhythmia. Results Patients with treated schizophrenia had higher rates of cardiac arrest and ventricular arrhythmia than controls, with rate ratios ranging from 1.7 to 3.2. Overall, thioridazine was not associated with an increased risk compared with haloperidol (rate ratio 0.9, 95% confidence interval 0.7 to 1.2). However, thioridazine showed an increased risk of events at doses >600 mg (2.6, 1.0 to 6.6; P=0.049) and a linear dose-response relation (P=0.038). Conclusions The increased risk of cardiac arrest and ventricular arrhythmia in patients with treated schizophrenia could be due to the disease or its treatment. Overall, the risk with thioridazine was no worse than that with haloperidol. Thioridazine may, however, have a higher risk at high doses, although this finding could be due to chance. To reduce cardiac risk, thioridazine should be prescribed at the lowest dose needed to obtain an optimal therapeutic effect.
Sudden cardiac death secondary to antidepressant and antipsychotic drugs
Expert Opinion on Drug Safety, 2008
A number of antipsychotic and antidepressant drugs are known to increase the risk of ventricular arrhythmias and sudden cardiac death. Based largely on a concern over QT prolongation and the development of life-threatening arrhythmias, a number of antipsychotic drugs have been temporarily or permanently withdrawn from the market or their use restricted. Some antidepressants and antipsychotics have been linked to QT prolongation and the development of Torsade de pointes arrhythmias, whereas others have been associated with a Brugada syndrome phenotype and the development of polymorphic ventricular arrhythmias. This review examines the mechanisms and predisposing factors underlying the development of cardiac arrhythmias, and sudden cardiac death, associated with antidepressant and antipsychotic drugs in clinical use.
Risk of Mortality Among Patients Treated With Antipsychotic Medications
Journal of Clinical Psychopharmacology, 2016
In this nationwide population-based study, we examined whether haloperidol exposure is associated with a higher risk of mortality than are other antipsychotic medications. Patients who newly received monotherapy with chlorpromazine (n = 2133), haloperidol (n = 4454), quetiapine (n = 1513), and risperidone (n = 1046) between January 1, 2001, and December 31, 2011, were selected from a random sample of the 1 million enrollees of the Taiwan National Health Insurance Research Database. The association between antipsychotic prescription and mortality was estimated through Cox proportional hazard regression. To examine the mortality rates of antipsychotics at different exposure durations, we compared the differences among short-term (≤30 days), midterm (31-90 days), and long-term (>90 days) antipsychotic use. The mortality rates during the follow-up among the chlorpromazine, haloperidol, quetiapine, and risperidone groups were 17.4%, 45.5%, 26.8%, and 25.9%, respectively. The mortality risk among patients receiving haloperidol was the highest within 30 days of the prescription, after which the risk reduced rapidly. Compared with the patients receiving chlorpromazine, the mortality risk was higher in short-term (adjusted hazard ratio, 2.11; 95% confidence interval, 1.87-2.39) and midterm haloperidol users (1.86; 1.54-2.25) than in long-term users (0.99; 0.61-1.61). In conclusion, haloperidol use is associated with higher mortality risk than other antipsychotic medications. The mortality risk varies according to the duration of drug exposure. Underlying characteristics and medical conditions may influence the estimation of the mortality risk. Clinicians should pay attention to the mortality risk when prescribing antipsychotic medications, particularly for the elderly and critically ill patients.

Antipsychotic medications have been increasingly and more widely prescribed despite continued uncertainty about their association with the incidence of acute myocardial infarction (AMI). We investigated the risk of AMI associated with antipsychotic treatment in 56 910 patients with schizophrenia, mood disorders, or dementia first hospitalized or visiting an emergency room for AMI in 1999 to 2009. A case-crossover design was used to compare the distributions of antipsychotic exposure for the same patient across 1 to 30 and 91 to 120 days just before the AMI event. Adjustments were made for comedications and outpatient visits. The adjusted odds ratio of AMI risk was 2.52 (95% confidence interval, 2.37-2.68) for any antipsychotics, 2.32 (95% confidence interval, 2.17-2.47) for first-generation antipsychotics, and 2.74 (95% confidence interval, 2.49-3.02) for second-generation antipsychotics. The risk significantly increased (P<0.001) with elevations in dosage and in short-term use (...

Sudden, unexpected death may occur in apparently healthy individuals. Its occurrence in psychiatric patients has raised the concern that the use of psychotropics, especially antipsychotics, may be associated with an increased risk of sudden death. This concern is maintained even though not all psychiatric patients who have succumbed to sudden death have been on psychotropics. Early reports presented the concern that the use of chlorpromazine and thioridazine were associated with sudden death. More recently, the focus shifted to the more potent agents. Indeed, the FDA Advisory Committee discussed the possibility of a connection between sudden death and haloperidol. No decision could be reached by the FDA Committee because of the enormous complexity of the problem. Nonetheless, since sudden death continues to catastrophically complicate the course of some patients, the scope of this review is to further investigate the relationship between antipsychotic agents and sudden death.
Antipsychotic drugs and risks of myocardial infarction: a self-controlled case series study
Eur Heart J, 2014
Antipsychotics increase the risk of stroke. Their effect on myocardial infarction remains uncertain because people prescribed and not prescribed antipsychotic drugs differ in their underlying vascular risk making between-person comparisons difficult to interpret. The aim of our study was to investigate this association using the self-controlled case series design that eliminates between-person confounding effects.
