To investigate the association of beta-blocker (BB) plasma levels with defibrillation outcomes and survival in patients with out-of-hospital cardiac arrest (OHCA).
Approach:
Key Findings:
31.4% of patients had detectable BB plasma levels on admission.
The most common BB detected was bisoprolol (25%), followed by metoprolol (22%) and carvedilol (15%).
Patients with detectable BB levels were older (median age 68 years), more likely to be female (higher percentage), and had higher rates of obesity, hypertension, and dyslipidemia.
Interpretation:
The study indicates an association between detectable beta-blocker levels and patient demographics.
Limitations:
The study was limited to a single center, which may affect the generalizability of the findings.
Information on home medication was unavailable for a significant proportion of patients.
Conclusion:
Further research is warranted to explore the implications of beta-blocker use in the context of out-of-hospital cardiac arrest.
Heart rate monitoring and atrial fibrillation detection had the strongest supporting evidence, but investigators found limited evidence for broader outpatient self-monitoring applications.
