Drug-related syncope is more common than previously thought, especially in cardiovascular patients. This study highlights the need to consider medication side effects when diagnosing syncope.

Area of Science:

  • Cardiology
  • Pharmacology
  • Emergency Medicine

Background:

  • Syncope is a common reason for emergency room visits.
  • The role of medications in causing syncope is not fully understood.
  • Previous studies have underestimated the prevalence of drug-related syncope.

Purpose of the Study:

  • To determine the incidence of drug-related syncope in emergency room patients.
  • To identify specific drugs and cardiovascular conditions associated with syncope.
  • To emphasize the importance of considering drug side effects in syncope diagnosis.

Main Methods:

  • Retrospective review of 483 emergency room patient records for syncope.
  • Analysis of patient data to identify drug-induced syncope.
  • Categorization of associated cardiovascular diseases and specific medications.

Main Results:

  • Forty-one patients (8.5%) experienced drug-related syncope.
  • Cardiovascular drugs were implicated in 39 cases, commonly for anginal syndrome, hypertension, and myocardial infarction.
  • Symptomatic orthostatic hypotension was frequent, linked to nitrates, beta-blockers, and other cardiovascular agents. Other reactions included heart block and anaphylaxis.

Conclusions:

  • Drug-related syncope is a significant and potentially under-recognized cause of syncope.
  • Cardiovascular medications are frequently implicated.
  • Clinicians should consider drug side effects in patients presenting with syncope, particularly those on cardiovascular therapy.
