  • Effect of Randomized Lipid Lowering With Simvastatin and Ezetimibe on Cataract Development (from the Simvastatin and Ezetimibe in Aortic Stenosis Study)

    • Recent American College of Cardiology/American Heart Association guidelines on statin initiation on the basis of total atherosclerotic cardiovascular disease risk argue that the preventive effect of statins on cardiovascular events outweigh the side effects, although this is controversial. Studies indicate a possible effect of statin therapy on reducing risk of lens opacities. However, the results are conflicting. The Simvastatin and Ezetimibe in Aortic Stenosis study (NCT00092677) enrolled 1,873 patients with asymptomatic aortic stenosis and no history of diabetes, coronary heart disease, or other serious co-morbidities were randomized (1:1) to double-blind 40 mg simvastatin plus 10 mg ezetimibe versus placebo. The primary end point in this substudy was incident cataract. Univariate and multivariate Cox models were used to analyze: (1) if the active treatment reduced the risk of the primary end point and (2) if time-varying low-density lipoproteins (LDL) cholesterol lowering (annually assessed) was associated with less incident cataract per se. During an average follow-up of 4.3 years, 65 patients (3.5%) developed cataract. Mean age at baseline was 68 years and 39% were women. In Cox multivariate analysis adjusted for age, gender, prednisolone treatment, smoking, baseline LDL cholesterol and high sensitivity C-reactive protein; simvastatin plus ezetimibe versus placebo was associated with 44% lower risk of cataract development (hazard ratio 0.56, 95% confidence interval 0.33 to 0.96, p = 0.034). In a parallel analysis substituting time-varying LDL-cholesterol with randomized treatment, lower intreatment LDL-cholesterol was in itself associated with lower risk of incident cataract (hazard ratio 0.78 per 1 mmol/ml lower total cholesterol, 95% confidence interval 0.64 to 0.93, p = 0.008). In conclusion, randomized treatment with simvastatin plus ezetimibe was associated with a 44% lower risk of incident cataract development. This effect should perhaps be considered in the risk-benefit ratio of statin treatment.

  • Effect Modifications of Lipid-Lowering Therapy on Progression of Aortic Stenosis (from the Simvastatin and Ezetimibe in Aortic Stenosis [SEAS] Study)
  • 2018
  • Ingår i: American Journal of Cardiology. - : Elsevier. - 0002-9149 .- 1879-1913. ; 121:6, s. 739-745

    • Observational studies indicate that low-density lipoprotein (LDL) cholesterol acts as a primary contributor to an active process leading to aortic stenosis (AS) development. However, randomized clinical trials have failed to demonstrate an effect of lipid lowering on impeding AS progression. This study explored if pretreatment LDL levels and AS severity altered the efficacy of lipid-lowering therapy. The study goal was evaluated in the analysis of surviving patients with baseline data in the Simvastatin and Ezetimibe in Aortic Stenosis (SEAS) trial of 1,873 asymptomatic patients with mild-to-moderate AS. Serially measured peak aortic jet velocity was the primary effect estimate. Linear mixed model analysis adjusted by baseline peak jet velocity and pretreatment LDL levels was used to assess effect modifications of treatment. Data were available in 1,579 (84%) patients. In adjusted analyses, lower baseline peak aortic jet velocity and higher pretreatment LDL levels increased the effect of randomized treatment (p >= 0.04 for interaction). As such, treatment impeded progression of AS in the highest quartile of LDL among patients with mild AS at baseline (0.06 m/s per year slower progression vs placebo in peak aortic jet velocity, 95% confidence interval 0.01 to 0.11, p = 0.03), but not in the 3 other quartiles of LDL. Conversely, among patients with moderate AS, there was no detectable effect of treatment in any of the pretreatment LDL quartiles (all p In conclusion, in a non prespecified post hoc analysis, the efficacy of lipid-lowering therapy on impeding AS progression increased with higher pretreatment LDL and lower peak aortic jet velocity (SEAS study: NCT00092677).

  • Relation of Lipid-Lowering Therapy to Need for Aortic Valve Replacement in Patients With Asymptomatic Mild to Moderate Aortic Stenosis
  • 2019
  • Ingår i: American Journal of Cardiology. - : Elsevier. - 0002-9149 .- 1879-1913. ; 124:11, s. 1736-1740

    • In this study, we aimed to determine if pretreatment low-density lipoprotein (LDL) levels and aortic stenosis (AS) severity alter the efficacy of lipid-lowering therapy on reducing aortic valve replacement (AVR). We used 1,687 patients with asymptomatic mild-to-moderate AS, who were randomly assigned (1:1) to 40/10 mg simvastatin/ezetimibe combination versus. placebo in the simvastatin and ezetimibe in aortic stenosis (SEAS) trial. Pretreatment LDL levels (>4 mmol/L) and peak aortic jet velocity (3 m/s) were used to partition study participants into 4 groups, which were followed for a primary endpoint of AVR. Cox regression with tests for interaction was used to study the effect of randomized treatment in each subgroup. During a median follow-up of 43 years (IQR 4.2 to 4.7 years; total 7,396 patient-years of follow-up), 478 (28%) patients underwent AVR and 146 (9%) died. A significant risk dependency was detected between simvastatin/ezetimibe combination, LDL levels and mild versus moderate AS on rates of AVR (p = 0.01 for interaction). In stratified analyses, randomized treatment, therefore, reduced the rate of AVR in patients with LDL levels >4 mmol and mild AS at baseline (HR 0.4; 95% CI: 0.2 to 0.9). There was no detectable effect of randomized treatment on the need for AVR in the 3 other participants subgroups. We conclude, that in a secondary analysis from a prospective randomized clinical trial, treatment with simvastatin/ezetimibe combination reduced the need for AVR in a subset of patients with mild AS and high pretreatment LDL levels.
