Abstract
UNLABELLED
The study indicates that hip fracture is independently associated with increased risk of coronary heart disease. In addition, the highest risk of coronary heart disease following hip fracture appeared within the first year after hip fracture, indicating the need for multidisciplinary care for the patients.
INTRODUCTION
Bone and vasculature are modulated through numerous common pathways. However, data on the risk of coronary heart disease (CHD) after hip fracture are scarce. Therefore, we investigated whether hip fracture increased the risk of CHD by conducting a large nationwide cohort study.
METHODS
Using universal insurance claims data from 2000 to 2010, we identified a study cohort of 6013 participants newly diagnosed with hip fracture and a control cohort of 23,802 participants. Both cohorts were followed up to the end of 2011 to evaluate the risk of CHD.
RESULTS
The overall incidence of CHD was 1.69-fold higher in the hip fracture cohort than it was in the control cohort (29.2 vs. 17.1 per 1000 person-years) with an adjusted hazard ratio of 1.51 (95 % confidence interval [CI] = 1.39-1.65). Sex-, age-, and comorbidity-specific analyses showed a higher relative risk of CHD for both women and men, all age groups, those with and without comorbidities, and patients with hip fracture compared with the control cohort. The highest risk of CHD was within the first year after hip fracture (adjusted HR = 1.72, 95 % CI = 1.45-2.04), and the risk remained high in the following years.
CONCLUSION
Hip fracture was independently associated with a subsequent risk of CHD.
