Atenolol  was the beta‐blocker most used .
Current evidence suggests that initiating treatment of hypertension with beta‐blockers leads to modest CVD reductions and little or no effects on mortality .
These beta‐blocker effects are inferior to those of other antihypertensive drugs .
Abstract Background Beta‐blockers refer to a mixed group of drugs with diverse pharmacodynamic and pharmacokinetic properties .
They have shown long‐term beneficial effects on mortality and cardiovascular disease ( CVD ) when used in people with heart failure or acute myocardial infa rct ion .
Beta‐blockers were thought to have similar beneficial effects when used as first‐line therapy for hypertension .
However , the benefit of beta‐blockers as first‐line therapy for hypertension without compelling indications is controversial .
This review is an up date of a Cochrane Review initially published in 2007 and up date d in 2012 .
Objectives To assess the effects of beta‐blockers on morbidity and mortality endpoints in adults with hypertension .
GRADE guidelines: 4. Rating the quality of evidence--study limitations (risk of bias).
In the GRADE approach , r and omized trials start as high- quality evidence and observational studies as low- quality evidence , but both can be rated down if most of the relevant evidence comes from studies that suffer from a high risk of bias . Well-established limitations of r and omized trials include failure to conceal allocation , failure to blind , loss to follow-up , and failure to appropriately consider the intention-to-treat principle . More recently recognized limitations include stopping early for apparent benefit and selective reporting of outcomes according to the results . Key limitations of observational studies include use of inappropriate controls and failure to adequately adjust for prognostic imbalance . Risk of bias may vary across outcomes ( e.g. , loss to follow-up may be far less for all-cause mortality than for quality of life ) , a consideration that many systematic review s ignore . In deciding whether to rate down for risk of bias -- whether for r and omized trials or observational studies -- authors should not take an approach that averages across studies . Rather , for any individual outcome , when there are some studies with a high risk , and some with a low risk of bias , they should consider including only the studies with a lower risk of bias
