The beneficial effects of anti-hypertensive agents on the cardiovascular system can be counterbalanced by the induction of metabolic disorders, such as hyperlipidaemia. The present trial evaluated the effect of the angiotensin II receptor antagonist, valsartan, on the lipid profile and glucose metabolism in patients with mild-to-moderate hypertension. This was a multicentre, randomized, double-blind, placebo-controlled study with a 3-week dietary run-in period under placebo; thereafter, patients received either valsartan 80 mg orally once daily or placebo for 12 weeks. A total of 123 patients were randomized, of whom 112 patients completed the study. Valsartan significantly lowered systolic blood pressure by 14.1 +/- 12.8 mmHg and diastolic blood pressure by 9.0 +/- 6.6 mmHg. In the placebo group, the corresponding values were 7.8 +/- 14.9 mmHg and 6.2 +/- 7.3 mmHg, respectively. Additionally, in the valsartan group, there was a significant decrease in levels of both low-density lipoprotein (LDL) cholesterol (valsartan, -6.3 +/- 24.9 mg/dl; placebo, +4.2 +/- 27.0 mg/dl) and total cholesterol (valsartan, -7.1 +/- 28.1 mg/dl; placebo, +6.0 +/- 29.4 mg/dl) in comparison with placebo. No significant changes were observed in the levels of triglycerides, high-density lipoprotein cholesterol, very low-density lipoprotein (VLDL) triglycerides, VLDL cholesterol and apolipoprotein B after valsartan treatment. No effect of valsartan was found with respect to fasting plasma glucose and glycosylated haemoglobin levels. Valsartan therapy was safe and well tolerated in our patient population. In conclusion, in addition to the marked decrease in blood pressure, valsartan significantly reduces total and LDL cholesterol levels and is neutral on glucose metabolism.

Antihypertensive therapy has been well established to reduce hypertension related morbidity and mortality, but the optimal therapy for Japanese patients remains unknown. The Valsartan Amlodipine Randomized Trial (VART), a prospective randomized open-label trial, was designed to determine whether treatment with an angiotensin II type 1 receptor blocker (valsartan) or a calcium channel blocker (amlodipine) lowers cardiovascular disease events in essential hypertensives in Japan. Registration, randomization and data entry were performed over the Internet. The minimization method (to control for age, gender, blood pressure level and history) was used at random assignment to ensure that the background factors were equivalent between the groups at baseline. After the registration, patients were followed-up for cardiovascular events (primary endpoints), echocardiography, (123)I-metaiodobenzylguanidine (MIBG) imaging, laboratory tests and blood pressure for 3 years. Currently, 797 patients have been enrolled and assigned to two groups: a valsartan (n=399) and an amlodipine (n=398) group. At baseline, controlled factors (age, gender, blood pressure level, and left ventricular hypertrophy) and the proportions of patients with diabetes and hyperlipidemia were equally allocated. At 12 months, both drugs evenly and significantly lowered blood pressure to the target level (valsartan: 133/79 mmHg; amlodipine: 132/79 mmHg). In conclusion, by combining the data on cardiovascular events with the results of echocardiographic, radionuclide imaging, and blood/urine studies, the VART study will provide mechanistic insights into the clinical outcomes and treatment effects of the trial.
