Back| Classification (class) | Symptoms |
|---|---|
| Class 0 | No symptoms due to atrial fibrillation |
| Class 1 | Symptoms due to atrial fibrillation have minimal effect on quality of life: - Symptoms are mild or occur occasionally - Single episode of atrial fibrillation without syncope or heart failure |
| Class 2 | Symptoms due to atrial fibrillation moderately affect quality of life: - Persistent atrial fibrillation patients have slight awareness of symptoms, or - Paroxysmal atrial fibrillation patients have very few episodes (e.g., no more than a few times a year) |
| Class 3 | Symptoms due to atrial fibrillation significantly affect quality of life: - Persistent atrial fibrillation patients have moderate awareness of symptoms most of the time, or - Paroxysmal atrial fibrillation patients have increased frequency of episodes (e.g., at least once every few months) and/or symptoms worsen |
| Class 4 | Symptoms due to atrial fibrillation severely affect quality of life: - Persistent atrial fibrillation patients find symptoms intolerable, and/or - Paroxysmal atrial fibrillation patients have frequent episodes with significant symptoms, and/or - Atrial fibrillation leads to syncope, and/or - Atrial fibrillation causes congestive heart failure |
Description
The CCS-SAF score is primarily used for bedside assessment of the severity of symptoms in atrial fibrillation patients and their impact on the patient's quality of life, providing clinical operability. It can also guide nursing and assist in assessing treatment efficacy.
Symptoms related to atrial fibrillation specifically refer to: palpitations, shortness of breath, dizziness (syncope), chest pain, and fatigue.
