Clinic blood pressure (CBP) is generally used for diagnosis and treatment monitoring in hypertension, but target organ damage correlates more closely with home blood pressure (HBP). Eliminating the clinic-home blood pressure difference (CHBPD) would make conventional CBP a more accurate alternative to HBP. This prospective, randomized, open trial compared the ...

The current guideline-recommended blood pressure values are difficult to maintain in general practice, partly due to the lack of ideal anti-hypertensive agents. Since morning hypertension has a high correlation with cardiovascular events, expectations that telmisartan, a long-acting angiotensin-II type-1 receptor blocker (ARB), can improve cardiovascular mortality are high. In this ...
