RT Journal A1 Gupta AK, Greller HA, Hoffman R T1 Β-blockers and cocaine: Still a bad idea JF Archives of Internal Medicine JO Archives of Internal Medicine YR 2011 FD November 8 VO 170 IS 20 SP 1859 OP 1860 DO 10.1001/archinternmed.2010.398 UL http://dx.doi.org/10.1001/archinternmed.2010.398 AB We read with interest the recent article examining the role of BBs in patients with presumed cocaine-associated chest pain.1 Although the authors concluded that BBs did not appear to be associated with adverse events such as death, dysrhythmias, or abnormal electrocardiographic findings, and were even perhaps beneficial, we believe that this is an overstatement and a potentially dangerous recommendation considering the limitations of this study. Being a retrospective study, there is no standardization of care between the 2 groups studied. The administration of BBs was left to the discretion of the treating physician, leading to a potential systemic bias. Furthermore, the group that received BBs also received significantly greater cardioprotective medications including nitroglycerin, aspirin, and statins, which may have skewed the data.
