Assessing your heart failure is important for when you have your appointment with your healthcare professional as the two scales below are based on how you feel and a measure of your symptoms. The doctor or nurse will want to know how you have been feeling since your last appointment and you can tell them where you fit into these two scales. You may find, for instance, you are NYHA Class II four days a week and feel more like NYHA Class III the other three days a week. The scales can also help you on a day-to-day basis in your everyday management of your condition and you can then relate this to your doctor or nurse at your next appointment. Your doctor will then work with you to grade your heart failure when you are first diagnosed and again at later visits. There are two systems used for grading heart failure and it is likely that your doctor will use a combination of both.
This system is used to classify how severe your condition is based on your symptoms.
|Class I (no symptoms)||You have no symptoms and can perform daily activities without feeling tired or short of breath.|
|Class II (mild symptoms)||You are comfortable when resting, but moderate activity makes you tired or short of breath.|
|Class III (moderate symptoms)||You are comfortable when resting, but even limited physical activity makes you tired or short of breath.|
|Class IV (severe symptoms)||You are unable to do any physical activity without discomfort and experience some symptoms at rest.|
This system accepts that heart failure can be present even before you get symptoms.
|Stage A||You don't have heart failure.
But you are at high risk due to having another medical condition that can lead to heart failure, such as high blood pressure, diabetes, obesity or coronary artery disease.
|Stage B||Your heart has been damaged by your other medical condition(s) or other factors, but you don't have any symptoms yet.|
|Stage C||Your heart is damaged and you are experiencing heart failure symptoms.|
|Stage D||You have severe heart failure that requires specialised care, despite receiving treatment.|
