lar diseases (1-10). Increased SBP leads to left ventricular hypertrophy, while decreased DBP results in decreased coronary circulation. Left ventricular hypertrophy accelerates the progression of cardiovascular remodeling, decreases left ventricular diastolic function, increases left ventricular end-DBP, and promotes endocardial ischemia. Thus, hypertension in elderly patients is associated with basic conditions of cardiac failure or ischemic heart disease. Therefore, antihypertensive drugs that decrease not only blood pressure (BP) but also arterial stiffness and PP are required for the treatment of such patients. We compared the effects of an angiotensin-receptor blocker (ARB), an angiotensin-converting
