Is Methamphetamine Use Associated With Idiopathic Pulmonary Arterial Hypertension?
Background: Amphetamine, methamphetamine, and cocaine are suspected of being pulmonary hypertension risk factors based on a small number of case reports along with pharmacologic similarities to fenfluramine, a diet drug associated with pulmonary arterial hypertension (PAH). We sought to determine whether rates of stimulant use are increased in patients believed to have idiopathic PAH compared with patients with PAH and known risk factors and patients with chronic thromboembolic pulmonary hypertension (CTEPH).
