Methamphetamine use and heart failure: Prevalence, risk factors, and predictors.

Objectives: To compare methamphetamine users who develop heart failure to those who do not and determine predictors.

Methods: Patients presenting over a two-year period testing positive for methamphetamine on their toxicology screen were included. Demographics, vital signs, echocardiography and labs were compared between patients with normal versus abnormal B-type natriuretic peptide (BNP).
