Abstract

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. 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. We screened 213 PD patients and randomly assigned 32 men and women with low-density lipoprotein cholesterol levels <130 mg/dL, high-sensitivity C-reactive protein levels of ≥1.5 mg/L, and LVDD, diagnosed by conventional and tissue Doppler imaging (TDI) echocardiography, to treatment with atorvastatin, 40 mg daily, or without. The primary end points were changes in TDI diastolic parameters or global strain imaging diastolic parameters. Atorvastatin reduced low-density lipoprotein cholesterol levels by 43% and high-sensitivity C-reactive protein levels by 45% (both P < .001). Follow-up TDI showed significant improvement of early mitral flow velocities divided by early diastolic peak velocities of the mitral annulus at the medial and lateral site (Nominal change for E/Emedial: -5.01 ± 6.36 vs 1.80 ± 6.59 fo...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
