ABSTRACT This subanalysis of the TNT (Treating to New Targets) study investigates the effects of intensive lipid lowering with atorvastatin in patients with coronary heart disease (CHD) with and without pre-existing chronic kidney disease (CKD).
Cardiovascular disease is a major cause of morbidity and mortality in patients with CKD.
A total of 10,001 patients with CHD were randomized to double-blind therapy with atorvastatin 80 mg/day or 10 mg/day. Patients with CKD were identified at baseline on the basis of an estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m(2) using the Modification of Diet in Renal Disease equation. The primary efficacy outcome was time to first major cardiovascular event.
Of 9,656 patients with complete renal data, 3,107 had CKD at baseline and demonstrated greater cardiovascular comorbidity than those with normal eGFR (n = 6,549). After a median follow-up of 5.0 years, 351 patients with CKD (11.3%) experienced a major cardiovascular event, compared with 561 patients with normal eGFR (8.6%) (hazard ratio [HR] = 1.35; 95% confidence interval [CI] 1.18 to 1.54; p < 0.0001). Compared with atorvastatin 10 mg, atorvastatin 80 mg reduced the relative risk of major cardiovascular events by 32% in patients with CKD (HR = 0.68; 95% CI 0.55 to 0.84; p = 0.0003) and 15% in patients with normal eGFR (HR = 0.85; 95% CI 0.72 to 1.00; p = 0.049). Both doses of atorvastatin were well tolerated in patients with CKD.
Aggressive lipid lowering with atorvastatin 80 mg was both safe and effective in reducing the excess of cardiovascular events in a high-risk population with CKD and CHD.

    ABSTRACT: Inflammation is highly prevalent in patients with chronic kidney disease (CKD) and is consistently associated with cardiovascular morbidity and mortality. Clinical event rates increase with declining renal function and activation of the acute-phase response. Statins are potent anti-inflammatory drugs that reduce the incidence of cardiovascular events. Owing to the increased prevalence of inflammation in patients with CKD and the potent effect of statins in individuals with elevated levels of C-reactive protein, these drugs should be especially effective in patients with CKD. Whereas data indicate that pravastatin may prevent loss of kidney function to a greater extent in individuals with evidence of increased inflammation than in those who show no inflammation, two large, randomized statin trials in patients on hemodialysis found no benefit of statin therapy, neither in the whole study group nor after stratifying for inflammation. Irrespective of inflammation, guidelines recommend treatment of dyslipidemia in early stages of CKD, which is supported by results from recent meta-analyses, and the Study of Heart and Renal Protection (SHARP), a large, randomized, placebo-controlled trial.

    ABSTRACT: Cardiovascular diseases such as coronary artery disease, congestive heart failure, arrhythmias and sudden cardiac death represent main causes of morbidity and mortality in patients with chronic kidney disease (CKD). Pathogenesis includes close linkage between heart and kidneys and involves traditional and non-traditional cardiovascular risk factors. According to a well-established classification of cardiorenal syndrome, cardiovascular involvement in CKD is known as "type-4 cardiorenal syndrome" (chronic renocardiac). The following review makes an overview about epidemiology, pathophysiology, diagnosis and treatment of cardiovascular complications in CKD patients.

    ABSTRACT: The National Kidney Foundation-Kidney Disease Outcomes Quality Initiative (NKF-KDOQI) guideline for management of dyslipidemia in chronic kidney disease (CKD) was published in 2003. Since then, considerable evidence, including randomized controlled trials of statin therapy in adults with CKD, has helped better define medical treatments for dyslipidemia. In light of the new evidence, KDIGO (Kidney Disease: Improving Global Outcomes) formed a work group for the management of dyslipidemia in patients with CKD. This work group developed a new guideline that contains substantial changes from the prior KDOQI guideline. KDIGO recommends treatment of dyslipidemia in patients with CKD primarily based on risk for coronary heart disease, which is driven in large part by age. The KDIGO guideline does not recommend using low-density lipoprotein cholesterol level as a guide for identifying individuals with CKD to be treated or as treatment targets. Initiation of statin treatment is no longer recommended in dialysis patients. To assist US practitioners in interpreting and applying the KDIGO guideline, NKF-KDOQI convened a work group to write a commentary on this guideline. For the most part, our work group agreed with the recommendations of the KDIGO guideline, although we describe several areas in which we believe the guideline statements are either too strong or need to be more nuanced, areas of uncertainty and inconsistency, as well as additional research recommendations. The target audience for the KDIGO guideline includes nephrologists, primary care practitioners, and non-nephrology specialists such as cardiologists and endocrinologists. As such, we also put the current recommendations into the context of other clinical practice recommendations for cholesterol treatment. Copyright © 2014 National Kidney Foundation, Inc.
