Stages and Types of Heart Failure

Often, heart failure doctors commonly diagnose and manage their patient's congestive heart failure using the current American College of Cardiology/American Heart Association practice guidelines. You may hear your physician describe your heart failure as either stage A, B, C, or D.

The heart failure ACC/AHA practice guideline stages include:

 

Stage A No symptoms, but patient has risk factors for heart failure.

Stage B

 

No symptoms, but patient has structural heart disease.
Stage C

Symptoms of heart failure, with presence of structural heart disease.

 

Stage D Symptoms of advanced heart failure, with presence of end-stage disease.

ACC/AHA's current practice guidelines for physician diagnosis and management of heart failure

Congestive heart failure is commonly described in four stages I, II, III, or IV. It can range from mild to severe. Staging of the disease is measured by the severity of your heart failure based on your level of daily physical activity.

It is important to understand that the stage of your heart failure can change depending on your symptoms, response to medications, and level of activity you are able to endure. It is essential to talk to your doctor about any changes in your health you may experience and regularly see your cardiologist for health monitoring.

Often, the New York Heart Association (NYHA) Functional Classification System is commonly used to describe your symptomatic stage of heart failure based on your level of capable daily physical activity.

The symptomatic stages of congestive heart failure include:

 

NYHA I

No symptoms at rest or with exertion

 

NYHA II

Symptoms with normal exertion (mild)

 

NYHA III

Symptoms with less than normal exertion (moderate)

 

NYHA IV

Symptoms at rest (severe)
