Kratom-Induced Cardiomyopathy Reported in Reversible Heart Failure Case
Source: Journal of the American College of Cardiology (JACC)
Why it matters
A newly published case of kratom-associated cardiomyopathy adds to the emerging cardiac safety signal, expanding the list of organ systems affected by the substance.
The big picture
Researchers from Crestwood Medical Center (Huntsville, Alabama) have documented a case of kratom use triggering acute cardiomyopathy with reversible heart failure. The condition resolved, but the case underscores that kratom can affect cardiac function and warrants cardiac monitoring in users.
Key findings
- Case involved reversible cardiomyopathy temporally related to kratom use
- Kratom-induced cardiomyopathy is described as rare but documented
- Researchers are from general internal medicine/cardiology setting in Alabama
- Case was presented at American College of Cardiology annual meeting
- Published in JACC, Volume 87, April 2026
What they say
This formal medical publication in a top-tier cardiology journal documents kratom-related cardiomyopathy as a rare but real complication requiring clinical attention.
Bottom line
**Kratom users should be aware that the substance can impact cardiac function, and clinicians should consider cardiac assessment in symptomatic users.**
