HEART DISEASE IN MAINE COONS

Maine Coon Kitten Heart Health Guide

Why Echocardiograms Are So Important

The Big Risk: Hypertrophic Cardiomyopathy (HCM)

Maine Coons are one of the highest-risk breeds for HCM — a genetic heart condition where the

heart muscle becomes abnormally thick.

- The thickened heart can’t pump efficiently

- Blood flow becomes turbulent

- Can lead to heart failure, blood clots, or sudden death

Many kittens and adult cats show no symptoms early on.

What Is an Echocardiogram?

An echocardiogram is a non-invasive ultrasound of the heart that allows a vet to measure heart wall

thickness, evaluate blood flow, detect early structural changes, and identify issues not heard on

exam.

Why Echocardiograms Matter

- Early detection saves lives

- Protects breeding programs

- Prevents sudden emergencies

Why Maine Coons Are Prone

Maine Coons often carry genetic mutations linked to HCM. Not all carriers show disease

immediately, which is why repeated screening is critical.

Prevention Tips

- Screen breeding cats regularly

- Perform genetic testing

- Maintain healthy weight and diet

- Reduce stress and toxin exposure

- Monitor for subtle symptoms

- Repeat screening over time

Bottom Line

Echocardiograms are essential for Maine Coon kittens. They help catch silent disease early,

prevent devastating outcomes, and protect the future of the breed
