ABSTRACT

BACKGROUND: Pain in chronic heart failure (HF) is a significant but often unrecognized symptom. Characteristics of pain in subjects with HF are largely undescribed. The study aimed to address a knowledge gap in the relationship between HF and pain by investigating the prevalence of chronic pain and chronic widespread pain (CWP) among subjects with HF. METHODS: Population data from the HUNT3 study in Norway (2006-2008, n = 50,802) was used. HF was measured by self-report. CWP was defined as having pain in both sides of the body, pain in the upper and lower limbs, and axial pain for at least 3 months in the last year. Associations between HF and CWP and HF and moderate to high pain intensity were analysed with logistic regression. RESULTS: Among subjects with HF in the general population, the prevalence of chronic pain was 67.8%, 20.7% had CWP, and 58.8% had moderate to high intensity pain. Compared to participants with cardiovascular disease but not HF, the odds of both CWP (OR = 1.6; 95% CI: 1.3-2.0) and moderate to high intensity pain (OR = 1.3; 95% CI: 1.3-1.8) were higher among participants with HF-controlled for age, sex, body mass index, and comorbidity. CONCLUSIONS: Our study confirmed the high prevalence of pain among HF subjects. This pain could not be explained by comorbidity or sociodemographic factors, which are relevant for clinical and research purposes. Pain management should not be restricted to cardiac-related pain but to chronic pain in general. SIGNIFICANCE: This epidemiological study corroborates previous studies reporting a high prevalence of pain in the HF-population. We found that the relationship between HF, CWP, and pain intensity could not be explained by comorbidity or sociodemographic factors, illustrating the burden of chronic pain related to HF. Our results expand the understanding of pain in HF and highlight the need to identify and manage chronic pain among individuals with HF, as widespread pain adds to the symptom burden in individuals with HF.

ABSTRACT

BACKGROUND: Epidemiological studies of chronic pain frequently report high prevalence estimates. However, there is little information about the development and natural course of chronic pain. METHODS: We followed a random sample of participants from a population-based study (HUNT 3) with annual measures over 4 years. RESULTS: Among those without chronic pain at baseline, the probability of developing moderate to severe chronic pain (cumulative incidence) during the first year was 5%, a pain status that was maintained among 38% at the second follow-up. The probability of developing chronic pain diminished substantially for those who maintained a status of no chronic pain over several years. Subjects with moderate to severe chronic pain at baseline had an 8% probability of recovery into no chronic pain, a status that was maintained for 52% on the second follow-up. The probability of recovery diminished substantially as a status of chronic pain was prolonged for several years. Pain severity, widespread pain, pain catastrophizing, depression and sleep were significant predictors of future moderate to severe chronic pain, both among subjects with and without chronic pain at baseline. CONCLUSION: These findings suggest that the prognosis is fairly good after a new onset of chronic pain. When the pain has lasted for several years, the prognosis becomes poor. The same social and psychological factors predict new onset and the prognosis of chronic pain. SIGNIFICANCE: The development and recovery of chronic pain is highly dependent on previous pain. The prognosis of chronic pain may be predicted well when considering its duration in combination with other clinical, social and psychological factors. Targeting modifiable prognostic factors may be particularly important for newly developed chronic pain.
