Effects of atorvastatin treatment on left ventricular diastolic function in peritoneal dialysis patients—The ALEVENT clinical trial

Background Left ventricular diastolic dysfunction (LVDD) is common among patients undergoing peritoneal dialysis (PD). Increased levels of inflammatory biomarkers, such as high-sensitivity C-reactive protein, predict the development of LVDD. Objectives We hypothesized that PD patients with elevated high-sensitivity C-reactive protein levels might benefit from statin treatment for LVDD and designed a randomized clinical trial to prove the hypothesis. Methods We screened 213 PD patients and randomly assigned 32 men and women with low-density lipoprotein cholesterol levels Results Atorvastatin reduced low-density lipoprotein cholesterol levels by 43% and high-sensitivity C-reactive protein levels by 45% (both P medial : −5.01 ± 6.36 vs 1.80 ± 6.59 for atorvastatin and control, respectively, P  = .02). There was also a significant improvement in global strain imaging after atorvastatin treatment (global strain rate, −17.12 ± 1.42 vs −14.61 ± 1.78 for atorvastatin and control, respectively, P  = .002 and E/SR IVR , 462.35 ± 110.54 vs 634.09 ± 116.81, P  = .003). Conclusions In this trial of PD patients without hyperlipidemia but with elevated high-sensitivity C-reactive protein levels and LVDD, atorvastatin significantly improved cardiac diastolic function (ClinicalTrials.gov number, NCT01503671).
