- Introduction Renal insufficiency is a known risk factor for cardiovascular disease. However, it is unknown if early impairment in renal function is associated with increased risk for aortic stenosis (AS). Recently a new approach was proposed to detect early impairment in renal function by using the ratio between glomerular filtration rate (GFR) calculated by cystatin C and GFR calculated by creatinine. Purpose To evaluate if the ratio between GFR cystatin C and GFR creatinine is associated with increased risk for AS requiring surgery and further, to evaluate if the ratio associates with survival. Methods We identified 334 patients that underwent surgery for AS after participation in population surveys (median age (interquartile range) 59.4 (10.3) years at survey and 68.3 (12.7) at surgery, 48% females). For each patient, two matched referents were allocated. Circulating levels of cystatin C and creatinine were determined at baseline (survey). Estimated glomerular filtration rates (eGFR) were calculated using the CAPA and Lund-Malmö-Revised formulas. Uni- and multivariable conditional logistic regression analyses were used to estimate the risk (odds ratio (OR) with [95% confidence interval]) related to one (ln) standard deviation increase in cystatin C, creatinine, eGFR cystatin C, eGFR creatinine, and in the ratio between eGFR cystatin C and eGFR creatinine, respectively. Results A high ratio was associated with lower risk for AS requiring surgery (OR 0.84 [0.73–0.97]). After stratification for sex, this effect was seen in women but not in men (0.74 [0.60–0.92] and 0.93 [0.76 [0.76–1.13], respectively). After further stratification for CAD, the association remained in women with CAD, but the effect was not seen in men with CAD (0.60 [0.44–0.83] and 0.96 [0.76 [0.75–1.23]). A high ratio was associated with longer survival in the entire cohort (HR 0.84 [0.75–0.95]). Conclusion A high ratio between eGFR based on cystatin C and eGFR based on creatinine was associated with lower risk for surgery for AS in those with CAD with a clear sex-difference. Early renal impairment is thus associated with future risk for AS requiring surgery. Further, a high ratio relates to longer survival.
