Renal function predicts cardiovascular outcomes in southern Italian postmenopausal women - PubMed (original) (raw)

Background: Postmenopausal women have an increased risk of adverse cardiovascular (CV) events. Similarly, chronic kidney disease (CKD) is a well established risk factor for CV disease and mortality.

Design: We evaluated the effect of renal function on the risk of death and CV events in 1500 southern Italian postmenopausal women.

Methods and results: Renal function was estimated (e) by glomerular filtration rate (e-GFR) by Modification of Diet in Renal Disease equation. We classified postmenopausal women in two groups of e-GFR (ml/min per 1.73 m(2)): > or =60 (group 1) and less than 60 (group 2). The primary endpoint was major adverse CV events (MACE). The secondary endpoints were total events (MACE + death from any cause), coronary events, and stroke. During the follow-up (mean=72.6 months), there were 200 new CV morbid events. The rate of MACE (per 100 patient-years) was 1.88 and 2.98 in the two groups of e-GFR (P<0.0001). On univariate analysis, the incident risk of CV events was inversely related with the e-GFR values; similarly, in multiple Cox regression model, only the e-GFR maintained an independent association with MACE and secondary end-points.

Conclusion: For the first time, we demonstrated that the reduction of e-GFR was associated with the increased risk of death and CV events, independently of traditional CV risk factors, menopause duration, and presence of metabolic syndrome.
