Study to Evaluate the Effect on Improvement of LVH by the Control of BP in Hypertension Patients With AV Disease

1.Primary objectives

• To evaluate changes from baseline in LVM at V5 (24M)

2.Secondary objectives

• To evaluate changes from baseline in LV global longitudinal strain at V5 (24M)
• To evaluate changes from baseline in E/E' (E: early diastolic LV inflow velocity, E': early diastolic mitral annulus velocity) at V5 (24M)
• To evaluate changes from baseline in LV volumes, a stroke volume index and LV ejection fraction at V5 (24M)
• To evaluate a rate of disease progression

• In case of Aortic stenosis (AS), to evaluate changes from baseline in Aortic Valve Area (AVA), Vmax, Mean Pressure Gradient (PG) and Valvulo-arterial impedance (Zva) at V5 (24M)
• In case of Aortic regurgitation (AR), to evaluate changes from baseline in Vena contracta at V5 (24M)
• To evaluate changes from baseline in blood pressure at V2(6M), V3(12M), V4(18M) and V5(24M)
• To evaluate a cumulative incidence rate for each visit time point

• Death, Cardiovascular(CV) death, Heart Failure(HF), Myocardial Infarction(MI), Hospitalization, Aortic Valve Replacement(AVR)
• To evaluate outcomes of adverse events, physical examination, vital signs (pulse) and laboratory tests (hematological examination, blood biochemical examination, urine test and pregnancy test)
