Abstract
In this focused update, the American Heart Association provides updated guidance for resuscitation of patients with cardiac arrest, respiratory arrest, and refractory shock due to poisoning. Based on structured evidence reviews, guidelines are provided for the treatment of critical poisoning from benzodiazepines, β-adrenergic receptor antagonists (also known as β-blockers), L-type calcium channel antagonists (commonly called calcium channel blockers), cocaine, cyanide, digoxin and related cardiac glycosides, local anesthetics, methemoglobinemia, opioids, organophosphates and carbamates, sodium channel antagonists (also called sodium channel blockers), and sympathomimetics. Recommendations are also provided for the use of venoarterial extracorporeal membrane oxygenation. These guidelines discuss the role of atropine, benzodiazepines, calcium, digoxin-specific immune antibody fragments, electrical pacing, flumazenil, glucagon, hemodialysis, hydroxocobalamin, hyperbaric oxygen, insulin, intravenous lipid emulsion, lidocaine, methylene blue, naloxone, pralidoxime, sodium bicarbonate, sodium nitrite, sodium thiosulfate, vasodilators, and vasopressors for the management of specific critical poisonings.

Clin Toxicol (Phila) 2023; 61:336-345. [PMID: 37171152 DOI: 10.1080/15563650.2023.2191819] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Revised: 03/07/2023] [Accepted: 03/11/2023] [Indexed: 05/13/2023]
Abstract
BACKGROUND It is well known that cocaine increases the risk of acute coronary syndrome. However, it is uncertain if the use of other stimulants, such as amfetamines and cathinones, is also related to acute coronary syndrome. OBJECTIVES To identify all reported cases of acute coronary syndrome related to the use of amfetamines and cathinones, the type of acute coronary syndrome, the atherothrombotic aetiology, and the mortality rate. METHODS A systematic literature search in PubMed, Embase database, Cochrane library, PsycInfo and Web of Science was performed from inception until 31 August 2022. All original articles in English or Dutch describing adult patients with acute coronary syndrome after the use of amfetamines or cathinones were included. The main outcome was the occurrence of acute coronary syndrome associated with amfetamine-type stimulants or cathinones. Data were collected and reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RESULTS A total of 11,605 articles were identified, 56 of which met the inclusion criteria. A total of 160 patients presented with acute coronary syndrome after five different types of amfetamines, namely, amfetamine (n = 48), metamfetamine (n = 98), 3,4-methylenedioxymetamfetamine (n = 11), fenethylline (n = 2), and 4-fluoroamfetamine (n = 1). Khat chewing was associated with acute coronary syndrome (n = 4234), as were three different types of synthetic cathinones, namely, non-defined cathinones (n = 1), 4-methylmethcathinone (n = 1), and α-pyrrolidinopentiophenone (n = 1). In patients with a known acute coronary syndrome type (n = 157), ST-segment elevation myocardial infarction was diagnosed in 53 patients (75%) and non-ST-segment elevation myocardial infarction in 18 patients (25%). Of the ST-segment elevation myocardial infarction patients, 36% were diagnosed with significant coronary stenosis or thrombus. The mortality rate for khat-associated acute coronary syndrome, with more often male and older patients with fewer cardiovascular risk factors, was higher compared to non-khat-associated acute coronary syndrome. For amfetamine, metamfetamine, and 3,4-methylenedioxymetamfetamine, mortality associated with ST--segment elevation myocardial infarction and non-ST-segment elevation myocardial infarction was 14% and 7%, respectively. Risk factors for acute coronary syndrome were infrequently reported, and risk stratification scores were not reported. CONCLUSION There is evidence that amfetamine-type stimulants and cathinones are associated with the occurrence of acute coronary syndrome. Khat chewing appears to be a risk factor for acute coronary syndrome. Amfetamine, metamfetamine, 3,4-methylenedioxymetamfetamine, fenethylline, 4-fluoroamfetamine, and synthetic cathinones were also reported in relation to acute coronary syndrome. However, this evidence is limited, of low quality and with a low number of reported cases. Further prospective studies need to be conducted.

Abstract
3,4-methylenedioxymethamphetamine or MDMA (known as "ecstasy") is a recreational drug of abuse, popular worldwide for its distinctive psychotropic effects. Currently, the therapeutic potential of MDMA in psychotherapy has attracted a lot of interest from the scientific community, despite the multitude of effects that this drug of abuse elicits on the human body. While neuronal effects have been the most studied, cardiovascular effects have also been described, as increased blood pressure and heart rate are the most recognizable. However, other effects have also been described at the cardiac (impaired cardiac contractile function, arrhythmias, myocardial necrosis and valvular heart disease) and vascular (vasoconstriction, disruption of vascular integrity and altered haemostasis) levels. Several mechanisms have been proposed, from the interaction with monoamine transporters and receptors to the promotion of oxidative stress or the activation of matrix metalloproteinases (MMPs). This review provides an overview of the cardiovascular implications of MDMA intake and underlying mechanisms, relevant when considering its consumption as drug of abuse but also when considering its therapeutic potential in psychiatry. Moreover, the risk/benefit ratio of the therapeutic use of MDMA remains to be fully elucidated from a cardiovascular standpoint, particularly in patients with underlying cardiovascular disease.

Abstract
La molécule de MDMA (3,4-méthylènedioxyméthamphétamine ou ecstasy) a plus de 100 ans. Sa consommation a explosé dans les années 1990, essentiellement dans un cadre « festif » ou « récréatif ». Elle a ensuite considérablement diminué au début des années 2000 et connaît actuellement un regain d’intérêt certain. Sa consommation a volontiers été considérée comme anodine avant qu’il n’apparaisse clairement qu’elle pouvait provoquer des décès, en l’absence même de « surdose ». Les mécanismes de toxicité sont multiples, complexes et imparfaitement élucidés. L’interaction avec les principaux neuromédiateurs est certaine. L’ecstasy est classée dans les produits empathogènes. Sa consommation vise à favoriser les relations sociales. De nombreux effets secondaires sont possibles. Les conditions de consommation, en ambiance confinée, avec une activité physique soutenue et prolongée favorisent la survenue des effets secondaires. Les effets secondaires bénins sont tolérés et considérés comme étant le « prix à payer » dans la recherche des effets psychogènes. En raison de son tropisme, les principales complications de la consommation d’ecstasy sont psychiatriques et neurologiques, mais aussi cardiovasculaires, respiratoires et métaboliques. Cependant, les formes graves de l’intoxication sont marquées par un tableau d’hyperthermie maligne responsable de complications multiples et pouvant conduire au décès. Tous les auteurs insistent sur la possibilité de complications, de formes graves, voire de décès après la consommation d’une dose unique de MDMA. Il n’y a pas de traitement spécifique. Le traitement symptomatique est au premier plan. Hydratation et sédation sont les clés de ce traitement.

Abstract
Better known as "ecstasy", 3,4-methylenedioxymethamphetamine (MDMA) is a small molecule that has played a prominent role in defining the ethos of today's teenagers and young adults, much like lysergic acid diethylamide (LSD) did in the 1960s. Though MDMA possesses structural similarities to compounds like amphetamine and mescaline, it produces subjective effects that are unlike any of the classical psychostimulants or hallucinogens and is one of the few compounds capable of reliably producing prosocial behavioral states. As a result, MDMA has captured the attention of recreational users, the media, artists, psychiatrists, and neuropharmacologists alike. Here, we detail the synthesis of MDMA as well as its pharmacology, metabolism, adverse effects, and potential use in medicine. Finally, we discuss its history and why it is perhaps the most important compound for the future of psychedelic science-having the potential to either facilitate new psychedelic research initiatives, or to usher in a second Dark Age for the field.

Abstract
AIM To examine the demographic characteristics, circumstances, toxicology and major organ pathology of MDMA-related deaths in Australia. METHODS Retrospective review of cases in which MDMA was a cause of death, as identified from the National Coronial Information System. RESULTS 82 cases over a 5-year period were identified. The majority of decedents were male (83%), with a median age of 26 years. Deaths were predominantly due to drug toxicity (82%), with MDMA the sole drug causing death in 23% of cases, and combined drug toxicity in 59% of cases. The remaining deaths (18%) were primarily due to pathological events/disease or injury, with MDMA a significant contributing condition. Cardiovascular pathology, typically atherosclerosis, was detected in 58% of decedents, with moderate-severe atherosclerosis in 23% of cases. The prevalence of such pathology is higher than that expected among similarly aged members of the general population. Cerebrovascular pathology, primarily cerebral haemorrhage and hypoxic damage, was present in 12% of cases. CONCLUSIONS MDMA has contributed to a clinically significant number of deaths in Australia. The prevalence of cardiovascular pathology was similar to that among methamphetamine and cocaine fatalities. Whilst cardiovascular pathology may reflect the use of other stimulants, the cardiotoxic properties of MDMA have been well-documented. Future studies examining MDMA-related morbidity and mortality in the context of other risk factors are recommended. Overall, the current study highlights the need to educate users about the potential harms of MDMA use, particularly that in conjunction with other stimulants, opioids and alcohol, which are known to increase overall toxicity.

Abstract
Repeated administration of 3,4-methylenedioxymethamphetamine (MDMA) (ecstasy) produces eccentric left ventricular (LV) dilation and diastolic dysfunction. While the mechanism(s) underlying this toxicity are unknown, oxidative stress plays an important role. MDMA is metabolized into redox cycling metabolites that produce superoxide. In this study, we demonstrated that metabolites of MDMA induce oxidative stress and contractile dysfunction in adult rat left ventricular myocytes. Metabolites of MDMA used in this study included alpha-methyl dopamine, N-methyl alpha-methyl dopamine and 2,5-bis(glutathion-S-yl)-alpha-MeDA. Dihydroethidium was used to detect drug-induced increases in reactive oxygen species (ROS) production in ventricular myocytes. Contractile function and changes in intracellular calcium transients were measured in paced (1 Hz), Fura-2 AM loaded, myocytes using the IonOptix system. Production of ROS in ventricular myocytes treated with MDMA was not different from control. In contrast, all three metabolites of MDMA exhibited time- and concentration-dependent increases in ROS that were prevented by N-acetyl-cysteine (NAC). The metabolites of MDMA, but not MDMA alone, significantly decreased contractility and impaired relaxation in myocytes stimulated at 1 Hz. These effects were prevented by NAC. Together, these data suggest that MDMA-induced oxidative stress in the left ventricle can be due, at least in part, to the metabolism of MDMA to redox active metabolites.

Abstract
The obesity epidemic currently plaguing the United States has spurred the development of a vast number of drugs to assist in the battle against obesity and its associated complications. The need to loose weight often causes patients to loose sight of or even ignore the serious side effects of some of the most widely used weight-loss medications. Here we present the case of ventricular tachycardia/fibrillation arrest in an otherwise healthy 48-year-old woman who was taking no medications other than phentermine, a common appetite suppressant that functions as a central nervous system stimulant through activation of the noradrenergic pathway of the sympathetic nervous system.

Abstract
AIMS Our aim was to determine whether the repeated, binge administration of 3,4-methylenedioxymethamphetamine (ecstasy; MDMA) produces structural and/or functional changes in the myocardium that are associated with oxidative stress. METHODS AND RESULTS Echocardiography and pressure-volume conductance catheters were used to assess left ventricular (LV) structure and function in rats subjected to four ecstasy binges (9 mg/kg i.v. for 4 days, separated by a 10 day drug-free period). Hearts from treated and control rats were used for either biochemical and proteomic analysis or the isolation of adult LV myocytes. After the fourth binge, treated hearts showed eccentric LV dilation and diastolic dysfunction. Systolic function was not altered in vivo; however, the magnitude of the contractile responses to electrical stimulation was significantly smaller in myocytes from rats treated in vivo with ecstasy compared with myocytes from control rats. The magnitude of the peak increase in intracellular calcium (measured by Fura-2) was also significantly smaller in myocytes from ecstasy-treated vs. control rats. The relaxation kinetics of the intracellular calcium transients were significantly longer in myocytes from ecstasy-treated rats. Ecstasy significantly increased nitrotyrosine content in the left ventricle. Proteomic analysis revealed increased nitration of contractile proteins (troponin-T, tropomyosin alpha-1 chain, myosin light polypeptide, and myosin regulatory light chain), mitochondrial proteins (Ub-cytochrome-c reductase and ATP synthase), and sarcoplasmic reticulum calcium ATPase. CONCLUSION The repeated binge administration of ecstasy produces eccentric LV dilation and dysfunction that is accompanied by oxidative stress. These functional responses may result from the redox modification of proteins involved in excitation-contraction coupling and/or mitochondrial energy production. Together, these results indicate that ecstasy has the potential to produce serious cardiac toxicity and ventricular dysfunction.

Abstract
Amphetamines are popular drugs of abuse, particularly among youngsters and at dance scenes. Cardiotoxicity (manifested as cardiomyopathy, acute myocardial infarction/necrosis, heart failure, or arrhythmia) after the recreational (mis)use of amphetamine and its synthetic derivatives has been documented but is rather rare. Amphetamine-related cardiac fatalities are even more rare. We present 6 cases of young persons who died unexpected after the chronic abuse of amphetamines. Death was not attributed to a lethal intoxication but to an acute myocardial necrosis, a right ventricle rupture, a cardiomyopathy, or an arrhythmia. Two of the deceased persons presented prior to their death to the emergency department, but their complaints were not considered (probably due to their young age) to be of cardiac origin. One case was a sport-related fatality where medical screening failed to identify the underlying cardiac pathology or the amphetamine abuse, and 1 case was a so-called idiopathic dilated cardiomyopathy where substance abuse was not considered by the treating physician. We think that amphetamine-associated cardiotoxicity is a rare but probably genuine entity that should be considered both in forensic and clinical/emergency medicine because of its potential medicolegal implications.

Abstract
XTC and other amphetamines are considered to be safe by the majority of partying young people who are unaware of (or unwilling to know about) the acute and chronic toxicity of these substances, and these drugs are widespread, illicit stimulants. In this article, we describe four cases of severe acute toxicity due to recreational use of amphetamines 3,4-methylene-dioxymethamphetamine, 3,4-methylenedioxyethylamphetamine, 3,4-methylenedioxyamphetamine, 4-methylthioamphetamine or p-methoxyamphetamine, with emphasis on the presenting symptoms and acute treatment in the emergency department.

Abstract
Early loss of renal grafts is generally caused by vascular or immunologic complications. We describe two patients who received a kidney transplant from the same donor and lost their grafts during the first posttransplant week. Both cases presented necrotizing graft vasculopathy without inflammatory element. The donor was a 21-year-old woman who regularly used "ecstasy" over a 2-year period. After an extensive work-up to investigate the potential causes of graft loss, we considered the possibility of ecstasy being the cause of these two renal-graft losses.

Abstract
This study examined the characteristics of gay men attending circuit parties and their drug use. In particular, the role of methylenediomethamphetamine (MDMA, "ecstasy") was considered in relation to other drug use and sexual behavior. A one-page survey was distributed to 173 men attending a circuit party. Respondents were generally gay men, Caucasian, employed, and well-educated. Twenty-five percent self-identified as HIV-positive. Eighty-six percent reported using at least one substance on the day of the party; polydrug use was frequent. The most common substances were MDMA, ketamine, and methamphetamine. MDMA use was highly associated with ketamine, methamphetamine, and cocaine use. MDMA use was also associated with significantly more receptive anal intercourse. Circuit parties are settings of increased drug use and associated high-risk sexual behavior. A better understanding of these issues is needed to develop interventions aimed at reducing drug use and sexual risk taking among gay men who attend circuit parties.

Abstract
Methylene 3, 4 dioxymethamphetamine (MDMA) has been gaining popularity as a recreational drug over the past few decades around the globe. Although once thought to be safer than its mother compound, amphetamine, several life-threatening adverse reactions have been reported. Among the cardiovascular toxicities documented, MDMA commonly causes various forms of arrhythmia and heart failure. However, MDMA-induced acute myocardial infarction is rarely reported. We report a case of acute myocardial infarction in a young man shortly after taking MDMA. Massive thrombosis over the right coronary artery was demonstrated by means of emergency angiography. After treatment with intravenous glycoprotein IIb/IIIa inhibitor and intracoronary urokinase infusion, the coronary artery was shown to be patent without any apparent stenotic lesions. The mechanism of MDMA-induced acute myocardial infarction was discussed.

Abstract
The abuse of alcohol is associated with chronic cardiomyopathy, hypertension, and arrhythmia. Abstinence or using alcohol in moderation can reverse these cardiovascular problems. Alcohol is also distinguished among the substances of abuse by having possible protective effects against coronary artery disease and stroke when used in moderate amounts. Amphetamines (eg, speed, ice, ecstasy) have many of the cardiovascular toxicities seen with cocaine, including acute and chronic cardiovascular diseases. Heroin and other opiates can cause arrhythmias and noncardiac pulmonary edema, and may reduce cardiac output. Cardiovascular problems are less common with cannabis (marijuana) than with opiates, but major cognitive disorders may be seen with its chronic use. It is still controversial whether caffeine can cause hypertension and coronary artery disease, and questions have been raised about its safety in patients with heart failure and arrhythmia.

Abstract
BACKGROUND Ecstasy is a neurotoxic and hepatotoxic drug. Brain edema and fulminant hepatic failure are two of the most serious complications associated with the consumption of ecstasy. Acute ecstasy intoxication can transform a patient into an organ donor or a hepatic graft recipient. MATERIALS AND METHODS In the last 5 years in our centers, we have had two multiorgan donors who died from ecstasy-induced brain edema and three patients who required urgent orthotopic liver transplantation for treatment of severe acute hepatocellular failure induced by this drug. We performed eight transplantations using the organs of these two brain-dead donors: one heart, one bipulmonary, three kidneys, one kidney-pancreas, and two livers. RESULTS Toxicity caused by ecstasy was not observed in any of the eight patients who underwent transplantation. The clinical state and the graft function of the heart, two liver, renopancreatic, and three kidney recipients were normal for a follow-up period that ranged between 7 months and 4.5 years. The lung recipient died from multiorgan failure secondary to bilateral pneumonia 5 days after the transplantation, and one of the kidney transplant patients died as a result of intestinal lymphoma 6 months after transplantation. The three liver transplantations in the three patients with ecstasy-induced fulminant hepatic failure were performed successfully using orthotopic transplantation. These three recipients are asymptomatic and have normal-functioning hepatic grafts after follow-up of 3.5 years, 15 months, and 11 months, respectively. CONCLUSIONS The thoracic and abdominal organs of people dying from ecstasy intoxication can be viable for transplantation. The short- and medium-term survival of the graft and of the recipient have been similar to that of other organ donors. Urgent liver transplantation is an effective therapeutic option in patients with ecstasy-induced acute hepatocellular failure.

Abstract
"Club drugs" have become alarmingly popular. The use of 3,4-methylenedioxymethamphetamine (MDMA, Ecstasy) and gamma-hydroxybutyrate (GHB), in particular, has increased dramatically from 1997-1999. The pharmacokinetics of MDMA and GHB appear to be nonlinear, making it difficult to estimate a dose-response relationship. The drug MDMA is an amphetamine analog with sympathomimetic properties, whereas GHB is a gamma-aminobutyric acid analog with sedative properties. Symptoms of an MDMA toxic reaction include tachycardia, sweating, and hyperthermia. Occasional severe sequelae include disseminated intravascular coagulation, rhabdomyolysis, and acute renal failure. Treatment includes lowering the body temperature and maintaining adequate hydration. Symptoms of GHB intoxication include coma, respiratory depression, unusual movements, confusion, amnesia, and vomiting. Treatment includes cardiac and respiratory support. Because of the popularity of these agents and their potentially dangerous effects, health care professionals must be familiar with these substances and the treatment options for patients who present with symptoms of a toxic reaction.
