Title: The Study Comparing the Incidence of Cardiovascular Events Between High-dose ARB Monotherapy and Combination Therapy With ARB and Calcium Channel Blocker in Japanese Elderly Hypertensive Patients at High Cardiovascular Risk
Brief Summary: The purpose of this study is to investigate whether high-dose angiotensin II receptor blocker (ARB) monotherapy or combination therapy with ARB and calcium channel blockers is more effective in reducing the incidence of cardiovascular events in Japanese elderly high-risk hypertensive patients not adequately controlled by standard dose ARB alone.
