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..

HISTORY AND ADMISSION FINDINGS: A 27-year-old man presented with acute dyspnea and a previous respiratory tract infection with progressive dyspnoea and chest pain over 2 weeks. Clinical findings revealed severe cardiac failure with development of cardiogenic shock and need for adrenergic drug therapy for circulatory support. INVESTIGATIONS: The electrocardiogram showed a sinus tachycardia with unspecific T-wave-inversions, the echocardiogram revealed a dilated left ventricle and severely reduced systolic LV-function...

UNLABELLED: HASH(0x50e6660) BACKGROUND: Methamphetamine (meth) is a stimulant used illegally around the world, including in Iran. Cardiomyopathy and cardiac failure may occur following chronic meth use and may cause the patients referred to the emergency department. CASE REPORTS: A 28-year old man and two women, ages 29 and 31-year-old, with a history of meth use, were admitted to the emergency department with severe dyspnea at rest. Each had sinus tachycardia with tachypnea and an echocardiogram that showed severe systolic dysfunction consistent with heart failure...

The present study investigated the molecular pathology of atrial and brain natriuretic peptides (ANP and BNP) in the myocardium to evaluate terminal cardiac function in routine forensic casework with particular regard to fatal drug intoxication (n = 18; sedative-hypnotics, n = 10; methamphetamine, n = 8), hypothermia (cold exposure, n = 13), and hyperthermia (heatstroke, n = 10), compared with that in acute ischemic heart disease (AIHD, n = 35) and congestive heart disease (CHD, n = 11) as controls (total n = 87; within 48 h postmortem)...

Eighteen male Wistar rats aged six weeks were divided equally into Methamphetamine (MA), Placebo and Control group. MA group were injected with 50mg/kg body weight of Methamphetamine hydrochloride (MAHCl) in normal saline, Placebo group were injected with normal saline only, while Control group not injected with anything. Five MA group rats died within four hours of injection and their hearts collected on the same day. Another MA group rat was sacrificed two days after injection. Placebo and control group were sacrificed at similar intervals...

We recently discovered that inhibiting neurons in the dorsomedial hypothalamus (DMH) attenuated hyperthermia, tachycardia, hypertension, and hyperactivity evoked by the substituted amphetamine 3, 4-methylenedioxymethamphetamine (MDMA). Neurons that synthesize orexin are also found in the region of the DMH. As orexin and its receptors are involved in the regulation of heart rate and temperature, they would seem to be logical candidates as mediators of the effects evoked by amphetamines. The goal of this study was to determine if blockade of orexin-1 receptors in conscious rats would suppress cardiovascular and thermogenic responses evoked by a range of methamphetamine (METH) doses...

BACKGROUND: Intoxication from the psychostimulant methamphetamine (METH) because of cardiovascular collapse is a common cause of death within the abuse population. For obvious reasons, the heart has been taken as the primary target for this METH-induced toxicity. The demonstration that failure of brain stem cardiovascular regulation, rather than the heart, holds the key to cardiovascular collapse induced by the pesticide mevinphos implicates another potential underlying mechanism. The present study evaluated the hypothesis that METH effects acute cardiovascular depression by dampening the functional integrity of baroreflex via an action on brain stem nuclei that are associated with this homeostatic mechanism...
