Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This projects examines the importance of the renin-angiotensin-aldosterone system and the sympathetic nervous system in the control of cardiac and vascular structure and function in subjects with hypertension.Patients with hypertension and left ventricular hypertrophy were randomized to an angiotensin receptor blocker or a beta adrenergic receptor blocker for 48 weeks. Repeat investigations of blood pressure, structure and function of the heart and the vascular tree, and neurohormones were performed. Two control groups, consisting of normotensive subjects and of hypertensive subjects with no cardiac hypertrophy were also examined for comparison.
