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 .

Influence of pretreatment systolic blood pressure on the effect of carvedilol in patients with severe chronic heart failure: the Carvedilol Prospective Randomized Cumulative Survival (COPERNICUS) study.
OBJECTIVES We sought to evaluate the influence of pretreatment systolic blood pressure ( SBP ) on the efficacy and safety of carvedilol in patients with chronic heart failure ( CHF ) . BACKGROUND Although beta-blockers reduce the risk of death in CHF , there is little reported experience with these drugs in patients with a low pretreatment SBP , who may respond poorly to beta-blockade . METHODS We studied 2,289 patients with severe CHF who participated in the Carvedilol Prospect i ve R and omized Cumulative Survival ( COPERNICUS ) trial . RESULTS Compared with placebo , carvedilol improved the clinical status and reduced the risk of death and the combined risk of death or hospitalization for any reason , for a cardiovascular reason , or for worsening heart failure ( p < 0.001 for all ) . The relative magnitude of these benefits did not vary as a function of the pretreatment SBP ( all interaction : p > 0.10 ) . However , because patients with the lowest SBP were at highest risk of an event , they experienced the greatest absolute benefit from treatment with carvedilol . The lower the pretreatment SBP , the more likely that patients would report an adverse event , be intolerant of high doses of the study drug , or require permanent withdrawal of treatment ( p < 0.001 for all ) . However , these risks were primarily related to the severity of the underlying illness and not to treatment with carvedilol . CONCLUSIONS The current study provides little support for concerns about using beta-blockers ( particularly those with vasodilatory actions ) in patients with severe CHF who have a low SBP . Pretreatment blood pressure can identify patients who have the greatest need for risk reduction with carvedilol
