Background: The type and severity of symptoms perceived by heart failure (HF) patients may be a useful prognostic predictor, but the impact of symptom perception on clinical events among HF patients has not been fully tested. Aim: To assess the symptoms perceived by HF patients using the Heart Failure Somatic Perception Scale (HFSPS) and to test whether symptom perception predicts short-term prognosis in HF patients.

Methods: Using the prospective observational design, we collected data from 315 outpatients with HF (mean age 73 ± 13 years, 72% male). Data included sample characteristics, BMI, BNP, comorbidities, ADL, depressive symptoms, symptom perception assessed by HFSPS at baseline, and clinical composite outcomes (readmission, all-cause death, and emergency department visits) at three months. HFSPS is a scale that assesses the degree to which 18 physical symptoms perceived by HF patients are bothersome in daily life. The study subjects were classified into low, medium, and high HFSPS total score groups. The impact of HFSPS on clinical composite outcomes was analyzed using the Cox proportional hazard model, considering the influence of covariates.

Results: The mean overall HFSPS score was 11.7 ± 12.3 points, with 87 patients (28%) in the low HFSPS group, 151 (48%) in the medium group, and 77 (24%) in the high group. Symptoms reported were nocturia (74.6%), shortness of breath (58.4%), fatigue (54.6%), malaise (44.5%), and cough (42.9%). Three-month composite event rate was 25.7%, with statistically significant differences between the HFSPS groups (16.1% in the low group, 23.2% in the medium group, and 41.6% in the high group (p=0.001). The results of analysis using the Cox proportional Hazard model using age, gender, BMI, BNP, comorbidities, depression, and ADL as covariates, the high HFSPS group had a significantly higher incidence of clinical composite. The incidence of clinical composite outcomes at three months was significantly higher in the high HFSPS group than in the other groups (HR=2.090 (95% CI=1.067-4.096), p=0.032).

Conclusions: Symptom perception, which can be regarded as a patient-reported outcome, is a promising predictor of short-term prognosis in HF patients.
