Systemic haemodynamics in borderline arterial hypertension: responses to static exercise before and under the influence of propranolol

Abstract

Young patients with borderline arterial hypertension respond to static muscular exercise with elevations of the brachial artery blood pressure, heart rate, and cardiac output, which are of similar magnitude as in normotensive control subjects. Intravenous propranolol did not abolish or significantly modify these responses. There is no indication of neurogenic hyperreactivity in borderline hypertension, and the acute regulation of the circulation is not abnormal.
