Systemic hypertension is highly prevalent in stable coronary artery disease, a pervasive comorbidity complicating the diagnostic performance and interpretation of non-invasive provocative tests in chest pain patients because of the ischaemic signals generated, despite normal or near normal coronary arteries, by hearts structurally readapted by long-term exposure to raised systemic blood pressure. Additional and unresolved problems posed by arterial hypertension in patients with stable coronary artery disease regard the benefits of antihypertensive treatment due to reports of irrelevant, if not detrimental, effect of blood pressure (BP) lowering in averting coronary relapses as well as the lack of association between BP levels and incident coronary events in survivors from acute myocardial infarction. Uncertainties extend to BP-independent cardioprotective effects of antihypertensive drugs, although the efficacy of renin-angiotensin system blockers in the long-term prevention of cardiovascular events in stable coronary artery disease patients has been shown by several studies, particularly when combined with amlodipine, a dihydropiridine calcium channel blocker. In contrast, the long-term effect of beta-blockers, the antihypertensive class most used in that clinical category, is not supported by strong evidence except that generated in patients with systolic dysfunction and early postmyocardial infarction recovery periods.
