Relationship between hypertension and angina pectoris.

Abstract

1 Many factors are of importance in the relationship between angina pectoris and hypertensive heart disease. Vascular resistance modifies the oxygen supply, whereas the oxygen demand is influenced by the systolic and diastolic BPs, the diastolic filling time and wall tension, the duration of systole and transmural pressure and the sympathetic stimulation to the heart. 2 The treatment of angina pectoris in patients with hypertensive heart disease should aim to reduce myocardial ischaemia, and it is suggested that beta‐adrenoceptor antagonists are most suitable, as they reduce BP, heart rate and myocardial contractility and thus oxygen demand. 1979 The British Pharmacological Society
