Validation of a New Simple Scale to Measure Symptoms in Atrial Fibrillation
Why the study?
Does the CCS-SAF scale accurately correlate with validated patient-reported quality of life and symptom severity measures in patients with atrial fibrillation?
Population
484 patients with documented atrial fibrillation, mean age 62.2 years, 67% men.
Comparison
Assessment using the Canadian Cardiovascular… vs Validated quality-of-life questionnaires

Implication
Supports CCS-SAF as valid AF symptom correlate; leaves open prospective validation before routine use.
Structured PICO
Does the CCS-SAF scale accurately correlate with validated patient-reported quality of life and symptom severity measures in patients with atrial fibrillation?
P
Population
484 patients with documented atrial fibrillation (62% paroxysmal and 38% persistent/permanent), mean age 62.2 years, 67% men.
I
Intervention
Assessment using the Canadian Cardiovascular Society Severity in Atrial Fibrillation (CCS-SAF) scale
C
Comparator
Validated quality-of-life questionnaires (SF-36 generic scale and disease-specific AFSS)
O
Outcome
Correlation between the SAF class and measures of symptom severity, physical and emotional components of quality of life, general well-being, and health care consumptionpatient reported
The CCS-SAF scale is a simple, valid bedside tool that closely approximates patient-reported quality of life and symptom severity in atrial fibrillation.
