CardioNerds (Drs. Amit Goyal and Dan Ambinder) join Dr. Emily Lee (LAC+USC Internal medicine resident) and Dr. Charlie Lin (LAC+USC Cardiology fellow) as the discuss an important case of stimulant-related (methamphetamine) cardiovascular toxicity that manifested in right ventricular dysfunction due to severe pulmonary hypertension. Dr. Jonathan Davis (Director, Heart Failure Program at Zuckerberg San Francisco General Hospital and Trauma Center) provides the ECPR for this episide. Audio editing by CardioNerds Academy Intern, student doctor Akiva Rosenzveig. With the ongoing methamphetamine epidemic, the incidence of stimulant-related cardiovascular toxicity continues to grow. We discuss the following case: A 36-year-old man was hospitalized for evaluation of dyspnea and volume overload in the setting of previously untreated, provoked deep venous thrombosis. Transthoracic echocardiogram revealed severe right ventricular dysfunction as well as signs of pressure and volume overload. Computed tomography demonstrated a prominent main pulmonary artery and ruled out pulmonary embolism. Right heart catheterization confirmed the presence of pre-capillary pulmonary arterial hypertension without demonstrable vasoreactivity. He was prescribed sildenafil to begin management of methamphetamine-associated cardiomyopathy and right ventricular dysfunction manifesting as severe pre-capillary pulmonary hypertension. CardioNerds is collaborating with Radcliffe Cardiology and US Cardiology Review journal (USC) for a ‘call for cases’, with the intention to co-publish high impact cardiovascular case reports, subject to double-blind peer review. Case Reports that are accepted in USC journal and published as the version of record (VOR), will also be indexed in Scopus and the Directory of Open Access Journals (DOAJ).

Case Media - stimulant-related (methamphetamine) cardiovascular toxicity Pearls - stimulant-related (methamphetamine) cardiovascular toxicity 1. Methamphetamine, and stimulants in general, can have a multitude of effects on the cardiovascular and pulmonary systems. Effects of methamphetamine are thought to be due to catecholamine toxicity with direct effects on cardiac and vascular tissues. Acutely, methamphetamine can cause vascular constriction and vasospasm, while chronic exposure is associated with endothelial damage. Over time, methamphetamine can cause pulmonary hypertension, atherosclerosis, cardiac arrhythmias, and dilated cardiomyopathy. 2. Methamphetamines are the second most commonly misused substances worldwide after opiates. Patients with methamphetamine-associated pulmonary arterial hypertension (PAH) have more severe pulmonary vascular disease, more dilated and dysfunctional right ventricles, and worse prognoses when compared to patients with idiopathic PAH. Additionally, patients with methamphetamine-associated cardiomyopathy and PAH have significantly worse outcomes and prognoses when compared to those with structurally normal hearts without evidence of PAH. Management includes multidisciplinary support, complete cessation of methamphetamine use, and guideline-directed treatment of PAH. 3. The diagnosis of pulmonary hypertension (PH) begins with the history and physical, followed by confirmatory testing using echocardiography and invasive hemodynamics (right heart catheterization). Initial serological evaluation may include routine biochemical, hematologic, endocrine, hepatic, and infectious testing. Though PH is traditionally diagnosed and confirmed in a two-step, echocardiogram-followed-by-catheterization model, other diagnostics often include electrocardiography, blood gas analysis, spirometry, ventilation/perfusion assessment,
