Why the study?
Do beta-adrenoceptor antagonists reduce myocardial ischaemia in patients with hypertensive heart disease and angina pectoris?
Do beta-adrenoceptor antagonists reduce myocardial ischaemia in patients with hypertensive heart disease and angina pectoris?
Beta-blockers are recommended for managing angina in hypertensive patients because they favorably alter the myocardial oxygen supply-demand balance.
Supports beta-blocker use in hypertensive angina; leaves open need for dedicated RCTs to confirm ischaemia reduction.
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.
