How will I know if my heart failure is early stage or advanced?
Talk with your doctor and ask questions about your concerns. Your doctor will be able to explain your unique disease process and address any other complications caused by other disease
(co-morbidity) you may have. Heart failure is often classified by the New York Heart Association (NYHA) according to symptoms. Your doctor may refer to this classification in the course of your care.
