Abstract
SUMMARY: Background: Chronic kidney disease (CKD) is an increasingly health disease all around the world with a high burden of mortality and cardiovascular (CV) morbidity rate. Even when renal replacement therapy is reached, more than half patients die, mainly for CV causes due either to uremia‐related cardiovascular risk factors (such as anemia, hyperhomocysteinemia, mineral bone disease–CKD with hyperparathyroidism, oxidative stress, hypoalbuminemia, chronic inflammation, prothrombotic factors) or to traditional ones (age, male gender, diabetes, obesity, hypertension, smoking, insulin levels, family history, dyslipidemia). Among the latter causes dyslipidemia represents one of the major, potentially correctable risk factor. Methods and Results: Statins have demonstrated to effectively and safely reduce cholesterol levels in CKD patients. Here we will examine the effects of statins on CV risk factors in CKD patients and particularly in patients on dialysis treatment, in the light of the unfavorable results of the large trials 4D and AURORA, recently published, underlining the role of malnutrition/inflammation as confounding factor. Probably it will be that only with a real prevention, starting statins even in the early stages of CKD, as indicated by post hoc analysis of large trials, that we will reach results in reducing the mortality rate in CKD patients. In the meanwhile, all the other remediable CV risk factors have to be at the same time corrected.
