La disfunsione renale come marcatore di rischio cardiovascolare.

The evaluation of urinary albumin excretion (UAE) and estimated glomerular filtration rate (eGFR) is suggested for the assessment of cardiovascular risk. It is unclear whether UAE and eGFR provide complementary information. UAE, eGFR, cardiovascular risk factors, and the incidence of cardiovascular disease were analyzed in 45- to 64-year-old individuals involved in the Gubbio study. UAE in the highest decile was defined as high (microng/min: > or = 18.6 in men and > or = 15.7 in women), eGFR in the lowest decile as low (mL/min/1.73 m(2): <64.2 in men and <57.9 in women). Kidney dysfunction was more frequent when defined by both markers than when defined by one marker only (UAE or eGFR) because high UAE and low eGFR tended to cluster in different individuals. The hazard ratio (HR) for incident cardiovascular disease was 1.85 in individuals with high UAE only (95%CI 1.04-3.25), 1.84 in individuals with low eGFR only (95%CI 1.04-3.26), and 5.93 in individuals with high UAE and low eGFR (95%CI 2.58-13.61). Concomitant evaluation of UAE and eGFR should be considered to adequately assess kidney dysfunction and cardiovascular risk.
