The development of methamphetamine-associated cardiomyopathy (MACM) represents a severe complication of chronic methamphetamine abuse. MACM-induced irreversible structural and functional changes in the heart can eventually lead to decompensated heart failure, ultimately requiring heart transplantation. In this case report we present a 47-year old male with a previous history of chronic amphetamine abuse who presented to the emergency room with severe dyspnea at rest associated with mild substernal non-radiating chest pain...

INTRODUCTION: Identification of patients with an increased risk of high defibrillation thresholds (DFTs) is important in planning implantable cardioverter-defibrillator (ICD) procedures. Clinical observations have suggested that patients with methamphetamine cardiomyopathy (MACMP) have significantly elevated defibrillation thresholds. We hypothesized that MACMP patients would have higher DFT thresholds than controls and would require procedural changes during ICD implantation to accommodate higher thresholds...

RATIONALE: Although amphetamines are recognized as "likely" agents to cause drug- and toxin-associated pulmonary arterial hypertension (PAH), (meth)amphetamine-associated PAH (Meth-APAH) has not been well described. OBJECTIVES: To prospectively characterize the clinical presentation, histopathology, and outcomes of Meth-APAH compared with those of idiopathic PAH (iPAH). METHODS: We performed a prospective cohort study of patients with Meth-APAH and iPAH presenting to the Stanford University Pulmonary Hypertension Program between 2003 and 2015...

BACKGROUND: Methamphetamine abuse is a worldwide health concern. Methamphetamine causes health hazards in many vital organs. It can cause damage to cardiac tissue via catecholamines release. Methamphetamine related deaths are becoming one of the most important problems in Iran. The purpose of the present study was to determine cardiac pathology in methamphetamine poisoning-related deaths. METHODS: The study included 100 cases of methamphetamine poisoning-related deaths and 100 cases as control group...

Parturients may present with evidence of acute heart failure or respiratory distress during the peripartum period. This case report documents utilization of "stand-by" extracorporeal membrane oxygenation (ECMO) for a 40-year-old woman with a history of severe left ventricular dysfunction who presented for elective dilation and evacuation of triplets at 20 weeks' gestation. The patient's medical history was significant for hypertension, diabetes mellitus, methamphetamine use (acute/chronic), and cardiac-respiratory arrest before her previous emergent cesarean delivery...

Methamphetamine is one of the most commonly abused illegal drugs in the United States. Health care providers are commonly faced with medical illness caused by methamphetamine. This study investigates the impact of methamphetamine use on the severity of cardiomyopathy and heart failure in young adults. This retrospective study analyzed patients seen at Arrowhead Regional Medical Center from 2008 to 2012. Patients were between 18 and 50 years old. All patients had a discharge diagnosis of cardiomyopathy or heart failure...

Ephedrine decongestant products are widely used. Common side effects include palpitations, nervousness, and headache. More severe adverse reactions include cardiomyopathy and vasospasm. We report the case of an otherwise healthy 37-year-old woman who presented with acute-onset quadriplegia and heart failure. She had a normal chest radiograph on admission, but developed marked pulmonary edema and bilateral effusions the next day. Echocardiography revealed a left ventricular ejection fraction of 0.18 and no obvious intrinsic pathologic condition such as foramen narrowing on spinal imaging...

The purpose of this study was to determine the prevalence of methamphetamine-associated congestive heart failure (MAC) and to evaluate the relationship between methamphetamine abuse and EF and functional status over time. A retrospective review of records from 2009 to 2014 was carried out. Prevalence of methamphetamine abuse among all patients admitted with CHF was calculated for each of the 6 years of the study (n = 141) and was compared with prevalence of cocaine abuse and alcohol abuse. For patients with two or more admissions during the entire time period, the trajectories of NYHA functional class and EF over time were determined (n = 58)...

Methamphetamine (METH) abuse is escalating worldwide, with the most common cause of death resulting from cardiovascular failure and hyperthermia; however, the underlying physiological mechanisms are poorly understood. Systemic administration of METH in anaesthetised rats reduced the effectiveness of some protective cardiorespiratory reflexes, increased central respiratory activity independently of metabolic function, and increased heart rate, metabolism and respiration in a pattern indicating that non-shivering thermogenesis contributes to the well-described hyperthermia...

BACKGROUND: Heart failure (HF) disproportionately affects Native Hawaiians and Other Pacific Islanders (NHOPIs). This study examines risk factors associated with left ventricular ejection fraction (LVEF) among 151 hospitalized NHOPI HF patients enrolled at a single tertiary care hospital between June 2006 and April 2010. METHODS: Enrollment criteria: (1) NHOPI by self-identification. (2) Age ≥ 21 yrs. (3) Diagnosis of HF defined: (a) left ventricular ejection fraction (LVEF) ≤ 40% or LVEF ≤ 60% with abnormal diastolic function and (b) classic HF signs/symptoms...

3,4-Methylenedioxy-N-methamphetamine (MDMA, ecstasy) is an amphetamine derivative and is a popular type of drug that is abused due to its effects on the central nervous system (CNS), including alertness and euphoria. However, life-threatening (brain edema, heart failure, and coma) and fatal hyperthermia sometimes occur in some individuals taking MDMA. In a one-generation reproductive toxicity study, the potential toxicity of chronic exposure of MDMA was investigated on the reproductive capabilities of parental mice (F0), as well as the survival/development of their subsequent offspring (F1)...

Methamphetamine (MA) is a psychostimulant. MA may induce numerous cardiotoxic effects, leading to cardiac arrhythmias, heart failure, eventually leading to sudden cardiac death. The deleterious effects of methamphetamine work in tandem to disrupt the coordinated electrical activity of the heart and have been associated with life-threatening cardiac arrhythmias. Remodeling of ion channels is an important mechanism of arrhythmia. Although arrhythmogenic remodeling involves alterations in ion channel expression, it is yet unknown whether MA induced electrical remodeling by affecting gene expression, and whether the changes in protein expression are paralleled by alterations in mRNA expression...

BACKGROUND: Methamphetamine (METH) has been associated with a dilated cardiomyopathy. The first and rate-limiting step of metabolism is dependent on the polymorphic enzyme CYP2D6. OBJECTIVES: To evaluate if polymorphisms in CYP2D6 can be associated with the development of a methamphetamine-induced cardiomyopathy. METHODS: We performed a prospective case-control pilot study. Cases were defined by a urinary drug screen positive for amphetamine and evidence of heart failure by beta natriuretic peptide (BNP) greater than 300 pg/ml and symptoms of heart failure...

A 26-year-old man was found unresponsive at work. When examined by emergency medical service responders, he had a temperature of 41.9°C, a heart rate of 150 beats per minute, unrecordable blood pressure, and a score of 4 on the Glasgow Coma Scale (eyes 1, verbal 2, motor 1; total scores range from..
