Kesäniemi Christoph Nienaber Simon Ray Terje Skjærpe Kristian Wachtell Ronnie Willenheimer Nonvoting members: Philippe Brudi (MSP), William Malbecq (MSD statistician) Rossebø et al. NEJM. 2008;359

4 Study Design Randomized Double blind Placebo controlled Multicenter 4 Weeks placebo/diet run-in Simvastatin 40 mg + ezetimibe 10 mg or placebo Median duration: 4.5 year (minimum follow-up 4 years)

5 Rossebø et al. NEJM. 2008;359 Primary Endpoint Major Cardiovascular Events: Cardiovascular death Aortic valve replacement surgery (AVR) CHF as a result of progression of AS Non-fatal myocardial infarction CABG PCI Hospitalized unstable angina Non-hemorrhagic stroke PCI = percutaneous coronary intervention CHF= congestive heart failure CABG = coronary-artery bypass grafting

6 Rossebø et al. NEJM. 2008;359 Secondary Endpoints Aortic Valve Events Aortic Valve Replacement CHF as a result of progression of AS Cardiovascular death Ischemic Cardiovascular Events Cardiovascular death Nonfatal MI CABG PCI Hospitalized unstable angina Nonhemorrhagic stroke

7 Rossebø et al. NEJM. 2008;359 Other Objectives Echocardiography Safety

8 Rossebø et al. NEJM. 2008;359 Patient Definition Men and Women Age 45 - 85 years Asymptomatic Valvular AS: ▬ Aortic valve thickening on echocardiographic evaluation ▬ Doppler jet velocity ≥2.5 - ≤4.0 m/sec Normal LV systolic function

9 Rossebø et al. NEJM. 2008;359 Exclusion Criteria Statin therapy or indication for statins Coronary heart disease Other important valvular disease ▬ Significant mitral valve stenosis or regurgitation ▬ Severe or predominant aortic regurgitation ▬ Rheumatic valvular disease or AV prosthesis or subvalvular (hypertrophic, obstructive cardiomyopathy) or supravalvular AS Diabetes Mellitus Other conditions precluding participation
