[Beta-blockade--a new therapeutic modality in chronic heart insufficiency].

Heart failure due to decreased left ventricular function is a condition with a considerable morbidity and mortality. Until recently beta-blocker treatment has been considered contraindicated in this condition. During the last 20 years a number of investigations have pointed to a possible positive effect of beta-blocker treatment in chronic heart failure and recently several major randomized trials have shown a significantly increased survival during beta-blocker treatment. This review summarizes the background for the use of beta-blocker treatment in chronic heart failure patients.
