Key result
Cocaine-related sudden cardiac death is hypothesized to be proarrhythmic in nature, driven by potent sodium channel blocking actions similar to agents like flecainide.
Why the study?
Does cocaine cause sudden cardiac death through proarrhythmic mechanisms in young otherwise healthy individuals?
Does cocaine cause sudden cardiac death through proarrhythmic mechanisms in young otherwise healthy individuals?
Cocaine-related sudden cardiac death may be primarily proarrhythmic, driven by its sodium channel blocking properties similar to class Ic antiarrhythmic drugs.

May warrant SCD risk counseling in cocaine users; leaves open prospective validation of sodium channel mechanism.
Sudden, unexpected death due to cocaine in young otherwise healthy individuals occurs in an idiosyncratic manner and is commonly felt to be arrhythmogenic in nature, although the exact cause of death is rarely documented. In addition to indirect sympathomimetic actions, cocaine is a potent sodium channel blocking drug and, in this regard, most closely resembles agents such as flecainide. We suggest that sudden death due to cocaine is proarrhythmic in nature, occurring under similar circumstances as that due to specific antiarrhythmic drugs.

Bauman et al. (1994) conducted a review in Cocaine-Related Sudden Cardiac Death. Cocaine was evaluated. Cocaine-related sudden cardiac death is hypothesized to be proarrhythmic in nature, driven by potent sodium channel blocking actions similar to agents like flecainide.
