CMP-MYTHiC Trial and Registry - CardioMyoPathy With MYocarditis THerapy With Colchicine

This trial (CMP-MYTHiC) is testing whether colchicine — a medication commonly used for gout and inflammation — can help patients who have inflammatory heart muscle disease (myocarditis) leading to heart failure or dangerous heart rhythms. Researchers want to see if reducing inflammation in the heart improves outcomes. **You may be eligible if...** - You are 18 years or older - You have been diagnosed with inflammatory heart muscle disease (inflammatory cardiomyopathy) with confirmed inflammation on a cardiac MRI - You are experiencing abnormal heart rhythms, reduced heart pumping function, or elevated heart stress markers **You may NOT be eligible if...** - You do not have evidence of heart muscle inflammation on cardiac MRI - You are under 18 years old - You have conditions that make colchicine unsafe (such as severe kidney or liver disease) Talk to your doctor to see if this trial is right for you.
