Current Approach and Treatment of Myocardial Infarction Associated with Cocaine Use

Abstract

Introduction: The global crisis of illicit substance consumption, particularly cocaine, extends beyond individual users, impacting social, cultural, and institutional levels. Cocaine use is associated with a myriad of illicit activities and significantly affects public health, especially in underdeveloped countries. This study examines the cardiovascular risks linked to cocaine use, focusing on conditions such as chest pain and acute myocardial infarction.

Methodology: A comprehensive review of the literature was conducted to explore the epidemiology, pathophysiology, and treatment strategies for cocaine-associated cardiovascular events. Data on cocaine use prevalence and related cardiovascular incidents were analyzed, alongside mechanisms of cocaine-induced myocardial damage and treatment protocols.

Results: Cocaine use has increased, particularly among young adults, leading to higher prevalence rates of cardiovascular events, including acute myocardial infarction. Cocaine induces vasoconstriction, arrhythmias, and oxidative stress, contributing to myocardial ischemia and infarction. The literature reveals a significant incidence of severe coronary atherosclerosis and multivessel disease among young cocaine users experiencing acute myocardial infarction. Immediate intervention strategies, including dual antiplatelet therapy and percutaneous coronary intervention, are essential but must be tailored to the unique challenges posed by cocaine's effects.

Conclusion: Cocaine use is directly linked to a significant increase in the risk of severe cardiovascular events, such as acute myocardial infarction, particularly among young, habitual users. The vasoconstrictive properties of cocaine, along with disruptions in the flow of ions and vasoactive molecules and an increased demand for myocardial oxygen, contribute to ischemia and potentially, infarction, especially in the presence of underlying atherosclerotic disease. Moreover, cocaine consumption can exacerbate or precipitate pre-existing cardiac   conditions   and significantly increase the likelihood of cardiac events, even in asymptomatic users, underscoring the need for preventive strategies and awareness of the specific dangers associated with this drug. The treatment of acute myocardial infarction in cocaine users involves unique challenges and requires a personalized approach. Initially, these patients should receive standard therapy, like non-users, but with specific considerations, such as avoiding selective beta-blockers in the early stages. Early   diagnosis and timely reperfusion therapy are critical to improving outcomes.
