Association of musculoskeletal pain with incidence and recurrence of cardiovascular disease: a longitudinal cohort in China

BACKGROUND: Globally, cardiovascular disease remains the leading cause of death and disability. Musculoskeletal pain, affecting nearly 30% of the global population, is increasingly recognized as a potential contributor to cardiovascular disease (CVD). However, its links to CVD persistence and recurrence in low- and middle-income regions remain unstudied. This study examines the association of musculoskeletal pain with both incident and recurrent CVD in a prospective cohort. METHODS: A prospective cohort analysis was performed using a nationally representative dataset of middle-aged and older population in China during 2011-2020. In the final analysis, 8,716 participants were evaluated for incident CVD, and 1,151 were examined for recurrent CVD events. The associations between musculoskeletal pain and both incident and recurrent CVD were examined using Cox proportional hazards regression and restricted cubic spline models. RESULTS: Participants with musculoskeletal pain showed a significantly higher CVD incidence rate than pain-free individuals throughout follow-up (3.45 vs. 2.43 per 100 person-years). Individuals with musculoskeletal pain had a 54% increased risk of recurrence (HR = 1.54, 95% CI: 1.28-1.85). Participants with multisite pain demonstrated progressively greater CVD risks, with significant trend for both incident and recurrent events (P trend < 0.001). All pain dynamics (generated, disappeared, intermittent, continuous) were significantly associated with both incident and recurrent CVD. CONCLUSIONS: Musculoskeletal pain is independently associated with both incident and recurrent CVD; prolonged pain duration and an increasing number of pain sites further amplify these risks.
