Substance Use Navigators: The Heroes Helping With Treatment of Methamphetamine Induced Cardiomyopathy
Methamphetamine induced cardiomyopathy is more than a heart failure diagnosis: it is a chronic disease at the intersection of cardiology, addiction medicine, mental health, and social determinants of health.
We can optimize every pillar of GDMT, but unless we address the underlying methamphetamine use disorder, we are often treating the consequence rather than the cause. This is where the Substance Use Navigator (SUN) becomes indispensable.
A SUN helps bridge the gap between the hospital and recovery by building trust with patients during hospitalization, providing motivational interviewing and harm reduction counseling, connecting patients to medication-assisted treatment and addiction services when appropriate, coordinating follow-up with community resources, helping address barriers such as housing, transportation, and insurance, and reducing the risk of recurrent admissions by supporting long-term recovery.
For patients with methamphetamine induced cardiomyopathy, recovery from substance use is often one of the most powerful heart failure therapies we can offer.
At Sharp Chula Vista Medical Center, integrating SUN into our multidisciplinary heart failure program has reinforced an important lesson: treating the heart means treating the whole person.
