TUESDAY, April 5 (HealthDay News) -- People with high blood pressure and impaired glucose tolerance seem to fare equally well when given two separate types of heart drugs, new research suggests. Although an angiotensin II receptor blocker (ARB) and a calcium channel blocker were both effective in this patient population, one difference did emerge, according to a presentation given Tuesday at the annual meeting of the American College of Cardiology in New Orleans: People taking Diovan (valsartan), an ARB, had a lower incidence of being hospitalized for congestive heart failure.
