Key result
Cocaine-related cardiac death stems primarily from chronic myocardial remodeling and genetics rather than acute overdose.
Why the study?
Cocaine-related deaths are often attributed to overdose, but the mechanisms are complex and not dose related, involving molecular and genetic factors.
What are the mechanisms of cardiovascular toxicity and sudden death associated with cocaine abuse?
What are the mechanisms of cardiovascular toxicity and sudden death associated with cocaine abuse?
Cocaine-related cardiovascular deaths are driven by chronic myocardial alterations and genetic factors rather than acute dose-related toxicity.

Shifts clinician focus to chronic exposure and genetics in cocaine users; leaves open prospective validation for risk stratification.
Steven B. Karch (2005) conducted a review in Cocaine cardiovascular toxicity. Cocaine abuse was evaluated. Cocaine-related cardiovascular deaths are primarily driven by prolonged use leading to myocardial alterations and genetic predispositions, rather than simple dose-related drug overdose.
