| Popis: | Angiotensin receptor blockers (ARBs), also known as sartans, block the activation of angiotensin type 1 receptors and have a recognised role in the treatment of heart failure and nephropathy. Since 2002, there have been three major outcome trials of ARBs in hypertension. We performed a meta-analysis to evaluate the impact of ARB on major outcomes. Randomised controlled trials of ARBs in hypertensive subjects with an average follow-up of at least 2 years and at least 100 major cardiovascular events were included. For each trial, the ARB used, number and characteristics of subjects, baseline and change in blood pressure, cardiovascular and noncardiovascular outcomes were recorded. Three trials involving 29 375 subjects were included in the meta-analysis. In Losartan Intervention For Endpoint (LIFE) and Study on Cognition and Prognosis in the Elderly (SCOPE) but not in Valsartan Antihypertensive Long-term Use Evaluation trial (VALUE), an ARB reduced the occurrence of the primary end point and stroke compared to control. Compared to other antihypertensive drugs, ARB treatment was associated with no significant change in all-cause mortality (relative risk ratio (RRR) 0.96, 95% CI: 0.88-1.06, P = 0.45). There was an increase in myocardial infarction (RRR, 1.12, 95% CI: 1.01-1.26, P = 0.041), but a decrease in new-onset diabetes mellitus (RRR, 0.80, 95% CI: 0.74-0.86, P < 0.0000001). In conclusion, the reduction in new-onset diabetes partly offsets any increase in the risk of myocardial infarction. Most hypertensive patients require more than one class of drugs. Small differences in treatment outcome should not over-ride the importance of good blood pressure control. |
