Haemodynamic and pulse wave responses to intravenous infusions of angiotensin II during chronic telmisartan therapy in normal volunteers.

Introduction: This study investigated the central haemodynamic, blood pressure (BP) and pulse wave responses to progressively increasing infusion rates of intravenous angiotensin II (Ang II) in normal volunteers during chronic therapy with telmisartan or placebo.

Materials And Methods: Ten normal volunteers, aged 21 33 years, completed a randomised, double-blind crossover study. Ang II was infused intravenously at increasing infusion rates (0 512 ng/minute) at the end of one week of telmisartan therapy (40 80 mg/day) and one week of placebo therapy.
