Abstract
Saga Telmisartan Aggressive Research (STAR) is a single-arm, prospective multi-center
trial to evaluate the effectiveness of treatment with telmisartan in patients with
hypertension. A total of 197 patients with a systolic blood pressure of ≥140 or a
diastolic blood pressure of ≥90 mmHg were enrolled in this study, and were prescribed
20 to 80 mg/day of telmisartan for 6 months. In all patients, both systolic and diastolic
blood pressures decreased (159±20 to 135±12 mmHg, p<0.0001, 87±12 to 75±8 mmHg, p<0.0001,
respectively). In addition, total cholesterol (TC) levels decreased from 200±40 to
188±33 mg/dl (p<0.05). In patients with TC ≥220 mg/dl, the change was more striking
(249±33 to 204±31 mg/dl, p<0.0001). Even in patients receiving statins, TC levels
still were decreased (216±51 to 190±31 mg/dl, p<0.02). In addition, TC levels were
also decreased even in patients receiving telmisartan in exchange for other ARBs with
TC ≥220 mg/d. Triglyceride (TG) levels were decreased (270±199 to 175±74 mg/dl, p<0.005)
in patients with TG levels ≥150 mg/dl. Fasting blood glucose (FBG) was decreased (158±68
to 138±60 mg/dl, p<0.05) in patients with FBG ≥110 mg/dl. These results suggest that
telmisartan may have favorable effects on lipid and glucose metabolism, in addition
to lowering blood pressure. The profound effect of telmisartan to lower cholesterol
suggests a potential use in hypertensive patients with dyslipidemia.
Key words
telmisartan - hypertension - dyslipidemia - cholesterol
