For Your Patients: Understanding Cardiomyopathy Progression

For patients with many types of cardiomyopathy, the disease gradually progresses from being "at risk for heart failure" to have structural heart disease, initially without symptoms and then with symptoms. The American College of Cardiology and American Heart Association classification for these are stages A through C.

Your condition is considered heart failure (Stage C) when you have had symptoms of the conditions, the most common of which are shortness of breath (dyspnea); feeling tired (fatigue); reduced ability to tolerate physical activity; weak legs; waking up to urinate; and swelling (edema) in the feet, ankles, lower legs, and torso.

Depending on which type of cardiomyopathy you have, how early it was diagnosed, and how well it is managed, you may reach a symptomatic stage quickly or after many years.

Life expectancy varies widely as well. With chronic heart failure, about 80% of people will survive for at least 1 year, about half live 5 years, and 30% will survive at least 10 years.

Following your treatment plan closely and notifying your healthcare team of changes in your condition may help slow down progression to end-stage heart failure, which is when the disease no longer responds to the standard medications and devices used to treat the condition, and patients may require transplant or other specialized interventions.
