Background: Previous studies have reported that high-dose strong statin therapy reduces the incidence of contrast-induced nephropathy (CIN) in statin naïve patients; however, the efficacy of high-dose strong statins for preventing CIN in real-world clinical practice remains unclear. The aim of this study was to evaluate the efficacy of strong statin therapy in addition to fluid hydration for preventing CIN after cardiovascular catheterization.Methods and Results: This prospective, multicenter, randomized controlled trial included 420 patients with chronic kidney disease who underwent cardiovascular catheterization. They were assigned to receive high-dose pitavastatin (4 mg/day × 4 days) on the day before and of the procedure and 2 days after the procedure (Statin group, n=213) or no pitavastatin (Control group, n=207). Isotonic saline hydration combined with a single bolus of sodium bicarbonate (20 mEq) was scheduled for administration to all patients. In the control group, statin therapy was continued at the same dose as that before randomization. CIN was defined as a ≥0.5 mg/dL increase in serum creatinine or ≥25% above baseline at 48 h after contrast exposure. Before randomization, 83% of study participants were receiving statin treatment. The statin group had a higher incidence of CIN than the control group (3.0% vs. 0%, P=0.01). The 12-month rate of major adverse cardiovascular events was similar between the 2 groups.Conclusions: High-dose pitavastatin increases the incidence of CIN in this study population.

Background: Accumulating evidence suggests that hematopoiesis, especially erythropoiesis, is disturbed in heart failure (HF) for many reasons. Low hemoglobin and red blood cell distribution width have emerged as prognostic indicators of HF independent of classic predictors. The prognostic implication of mean corpuscular volume (MCV) in HF, however, is unknown. In this context, we investigated the relationship between MCV and prognosis of acute decompensated HF (ADHF). Methods and Results: This retrospective cohort study consisted of 458 consecutive patients with ADHF who had emergency admission to hospital. Patients were divided into 2 groups: MCV ≤100fl (non-macrocytic group, n=400); and MCV >100fl (macrocytic group, n=58). The relationship between MCV and all-cause death was tested using Cox proportional hazard models, adjusting for other predictors. Mean patient age was 72.4 years and mean MCV was 93.0±7.1fl. Hemoglobin was significantly lower in the macrocytic group than the non-macrocytic group. During the mean follow-up of 20.8 months, a total of 173 deaths (37.9%) occurred. Kaplan-Meier analysis showed that all-cause death was significantly higher in the macrocytic group (log-rank P<0.0001). Cox proportional hazards analysis indicated that macrocytosis was an independent predictor of all-cause death (hazard ratio, 2.288; 95% confidence interval: 1.390–3.643; P=0.0015) after adjustment in the multivariate model. Conclusions: It is proposed for the first time that MCV is an independent predictor of all-cause death in patients with ADHF.  (Circ J 2013; 77: 2766–2771)
