Predicting Trends in Dyspnea and Fatigue in Heart Failure Patients' Outcomes
並列摘要
Background: Dyspnea and fatigue are distressing symptoms commonly seen in heart failure (HF) patients, and are closely related to patients' disease trajectory of contributes. Identifying the effect of symptom trends on disease outcomes is important to develop effective symptom management interventions in HF patients.Methods: One hundred and twenty-two patients were recruited. Dyspnea, fatigue, clinical characteristics, and disease outcomes were measured at the baseline assessment, three months, and 12 months. Latent class growth model and Kaplan-Meier survival analysis were used on dyspnea and fatigue to examine the relationship of disease trajectories and effects on disease outcomes.Results: A total of 122 patients were examined (mean age 62.8 ± 13.0 yrs; 79% male; 39% NYHA III/IV; 48% preserved systolic function HF). Three groups based on HF patients' dyspnea-fatigue trends were identified as ”constant good,” ”recovery,” and ”getting worse.” The cumulative incidence of a first cardiac event in both dyspnea and fatigue groups yielded similar results. The quality of life score for the getting worse group was significantly higher than that of the constant good and recovery groups. The result of the log-rank test was significant (X^2 = 8.11, p = 0.017). Post hoc comparison showed that the prognosis status of the constant good group was better than that of the getting worse (p = 0.046) and recovery groups (p = 0.020), while getting worse and recovery groups did not differ in prognosis status (p = 0.30).Conclusions: The results demonstrate the value of tracking symptoms over time to determine symptom trajectories as well as severe baseline (even with improvements at follow-ups) or increased fatigue over time were related to a worse event-free survival as compared with low but stable fatigue.
