Psychostimulants are a diverse range of substances that encompass cocaine and the phenylethylamines, the latter including the amphetamines, cathinones and some 'novel psychoactive substances'. This paper examines the range of pathophysiological processes, clinical presentations and treatment options involving the heart and cardiovascular system both in the acute setting and where long-term effects of psychostimulant use have affected the cardiovascular system. A common feature of these drugs is their effect on the cardiovascular system, where their major action is that of sympathomimetic amines with short- and long-term stimulation of the adrenergic system and consequent effects on blood pressure, cardiac modelling, atherogenesis and cellular calcium signalling. Cocaine additionally exhibits a variety of prothrombotic effects, effects on inflammatory mediators and alterations in myocardial gene expression. Persistent psychostimulant use results in progressive cardiovascular pathology, largely in the form of accelerated atherosclerosis, hypertension and myocardial ischaemia. Abstinence results in at least partial reversal of pathology. To a large extent, an assumption is made that treatment protocols used for cocaine-associated cardiovascular pathology apply to the amphetamines and other phenylethylamines, but there appears to be little research in this area, despite acknowledgement that cocaine and the better-known amphetamines have different modes of action.

Cocaine is a potent sympathomimetic drug usually associated with cardiotoxicity, including ventricular arrhythmia, systemic hypertension and acute myocardial infarction. It constitutes the most frequent cause of drug-related death reported by medical examiners in the US, and these events are most often related to the cardiovascular manifestations of the drug. However; to the best of our knowledge; cocaine induced acute myocarditis has very rarely been reported. We describe the case of a 19 year-old male regular user of marijuana and cocaine who was admitted for a suspicion on an acute lateral-wall myocardial infarction and in whom the final diagnosis of acute cocaine myocarditis has been made. We report diagnosis modalities and evolution.

Spontaneous isolated superior mesenteric artery dissection (SISMAD) is a rare potentially fatal disease. We present a case of cocaine-related SISMAD in a patient with abdominal pain. A 38-year-old African American male with hypertension and alcohol, cocaine, and tobacco abuse presented with abdominal pain and recent cocaine use. A CT angiogram revealed SISMAD; he was treated with conservative management. Cocaine and SISMAD share similar pathophysiologic mechanisms pertaining to vascular smooth muscle cell apoptosis and increased shear stress at fixed vascular positions. Our report emphasizes the need to consider cocaine abuse in SISMAD pathophysiology, risk stratification, and treatment algorithms in future studies.

Cocaine has been used increasingly nowadays because of its abundant availability and recreational effects. Along with that, we have been experiencing many cases presenting with cocaine intoxication and withdrawal effects, including hypertension and chest pain syndrome. In the modern era, many medical advances related to myocardial infarction treatment have been made, including not only medical therapy but also urgent or emergent reperfusion, and revascularization therapies. In percutaneous coronary revascularization therapy, a second-generation drug-eluting stent (DES) with dual antiplatelet therapy is the first-line treatment compared to bare-metal stent (BMS) with significant reduced risk of stent thrombosis and restenosis. However, there is limited clinical and research data on how to approach cocaine-induced myocardial infarction (CIMI) and it remains unclear what would be the optimal stent type we should use in CIMI. We, hereby, would like to describe a case of cocaine-related ST-segment elevation myocardial infarction (STEMI) requiring emergent percutaneous coronary intervention with a DES and clinical outcome. We also performed a literature review of cocaine-induced acute myocardial infarction management.
