Hypertensiebehandeling: angiotensine-II-antagonisten mogelijk beter dan ß-blokkers in het voorkómen van cardio- en cerebrovasculaire schade; de LIFE-studie in perspectief

- Current clinical guidelines state that only beta-blockers, diuretics, calcium channel antagonists and ACE inhibitors should be used for initial pharmacotherapy for uncomplicated hypertension. On basis of experience, efficacy and costs beta-blockers and diuretics are first choice. However, the importance of the renin-angiotensin-aldosterone-system in the pathophysiology of hypertensive end-organ damage is increasingly recognised nowadays, and modulation of this system may therefore exert favourable effects on cardiovascular and cerebrovascular complications. In the LIFE study, a recently published double-blinded, randomised trial, the angiotensin-II receptor (A-II) antagonist losartan was compared with the beta-blocker atenolol in patients with essential hypertension and left ventricular hypertrophy (LVH). Patients randomised to the A-II antagonist suffered statistically significantly fewer clinical end-points, specifically fewer cerebrovascular accidents, whereas both treatments resulted in a similar decrease in blood pressure. In the subset of diabetic patients, the use of the A-II antagonist yielded an even more favourable outcome. In our opinion, it should now also be permitted to prescribe A-II antagonists as initial pharmacotherapy for patients with uncomplicated essential hypertension. It might be considered to prescribe A-II antagonists as preferred treatment for patients with essential hypertension and known LVH, especially in diabetic patients.
