The latest FDA-approved treatment for obstructive hypertrophic cardiomyopathy (oHCM)
MYQORZO is a once-daily pill used to improve symptoms and ability to be active in adults with symptomatic obstructive HCM. It’s a cardiac myosin inhibitor (CMI), designed specifically to address the abnormalities in the heart muscle protein that lead to obstructive HCM. This helps the heart muscle contract and relax more normally and reduces obstruction.
Normal blood flow from the heart helps with your ability to be active
Reduced blood flow out of the heart leads to symptoms and can limit your ability to be active.
Learn about symptoms

Obstructive HCM causes excessive contractions in the heart muscle

MYQORZO helps the heart muscle relax so blood flows more easily
Unlike beta blockers and calcium channel blockers, MYQORZO works by directly targeting myosin proteins in the heart muscle to reduce obstruction
Normal heart
A heart without obstructive HCM contracts and relaxes to pump blood and oxygen throughout the body.
What does an obstructed heart look like?
Heart with obstructive HCM
In a heart with obstructive HCM, the walls get thick and stiff and can restrict blood flow out of the heart. This causes the symptoms of obstructive HCM.
What happens inside the heart walls?
Normal heart contraction
In a normal heart, 2 proteins called myosin and actin interact within the muscle cells to cause the heart to contract and relax. Think of myosin like rowers grabbing and pulling paddles through the water (actin) to help the boat move.
Obstructive HCM heart contraction
In a heart with obstructive HCM, there are more active myosin proteins than normal, which causes the heart muscle to contract too strongly.
How does MYQORZO work?
With MYQORZO
MYQORZO may help improve symptoms for people with obstructive HCM by binding to and blocking overactive myosin proteins.
This helps the heart muscle contract and relax more normally and reduces obstruction.

MYQORZO in your body
Once in the body, MYQORZO is reversible
Reaches and stays at steady levels
The medicine you have in your body will reach a steady level with regular dosing, helping your medicine maintain a consistent effect. Taken as directed, MYQORZO reaches a consistent effect within about 2 weeks (17 days).
If your healthcare provider needs to lower or temporarily stop MYQORZO, this effect reverses within 24-48 hours of your last dose.
