Objective. Evaluate the relationship between Framingham cardiovascular risk scores (FRS) and transplant-related factors, particularly renal function, in a stable liver transplant population. %26lt;br%26gt;Methods. Single-center retrospective study of 54 post liver transplant patients followed in one outpatient clinic. Demographics and laboratory data were assessed using the modified FRS (2009). Standard statistical analyses were performed between FRS and transplant-related factors; patient demographics, new-onset diabetes after transplant (NODAT), immunosuppressives, and estimated glomerular filtration rate (eGFR) measured by isotope dilution mass spectrometry (IDMS) and Cockcroft-Gault (CG) equations. %26lt;br%26gt;Results. Forty percent of patients were classified as low FRS, 29.6% as moderate FRS, and 29.6% as high FRS (of whom 50% had NODAT). Immunosuppressant use was similar between the high- and low-risk groups. FRS inversely correlated with eGFR (P = .0001) measured by either equation. eGFR measured by IDMS in the high-risk group (60.4 +/- 22.1 mL/min/1.73 m(2)) was significantly lower than that in the low-risk group (97.1 +/- 54 mL/min/1.73 m(2); P = .0001). In the multivariate analysis, age, eGFR and NODAT were significantly different between the low- and high-risk FRS groups. Receiving operational characteristic (ROC) analysis identified eGFR measured by IDMS at 42.7 mL/min/1.73 m(2) with a sensitivity of 92%, specificity of 19%, and positive predictive value of 72% to identify high-risk patients. Box-plot analysis of variance between eGFRs in the three risk groups showed a P value of .001. %26lt;br%26gt;Conclusions. In this study one-third of liver transplant patients had a high FRS, and 14.8% had an eGFR below 40 mL/min/1.73 m(2). Low eGFR predicts those with high FRS. Liver transplant patients particularly those with NODAT, with low eGFR should undergo close management of cardiovascular risk factors.
