ABSTRACT: Background
Kidney disease has been associated with venous thromboembolism (VTE) risk, but results conflict and there is little information regarding blacks.Study design
Prospective cohort study.Setting & participants
30,239 black and white adults 45 years or older enrolled in the REGARDS (Reasons for Geographic and Racial Differences in Stroke) Study 2003 to 2007.Predictors
Estimated glomerular filtration rate (eGFR) using the combined creatinine-cystatin C (eGFRcr-cys) equation and urinary albumin-creatinine ratio (ACR).Outcomes
The primary outcome was adjudicated VTE, and secondary outcomes were provoked and unprovoked VTE, separately. Mortality was a competing-risk event.Results
During 4.6 years of follow-up, 239 incident VTE events occurred over 124,624 person-years. Cause-specific HRs of VTE were calculated using proportional hazards regression adjusted for age, sex, race, region of residence, and body mass index. Adjusted VTE HRs for eGFRcr-cys of 60 to <90, 45 to <60, and <45 versus ≥90mL/min/1.73m2 were 1.28 (95% CI, 0.94-1.76), 1.30 (95% CI, 0.77-2.18), and 2.13 (95% CI, 1.21-3.76). Adjusted VTE HRs for ACR of 10 to <30, 30 to <300, and ≥300 versus <10mg/g were 1.14 (95% CI, 0.84-1.56), 1.15 (95% CI, 0.79-1.69), and 0.64 (95% CI, 0.25-1.62). Associations were similar for provoked and unprovoked VTE.Limitations
Single measurement of eGFR and ACR may have led to misclassification. Smaller numbers of events may have limited power.Conclusions
There was an independent association of low eGFR (<45 vs ≥90mL/min/1.73m2) with VTE risk, but no association of ACR and VTE.
