    Abstract:
    The use of beta-blockers in heart failure for a long time was regarded as contra-indicated because of their negative inotropic effects. Nevertheless, there is growing evidence that beta-blockers slow down the progression of left ventricular dilatation that characterizes heart failure. In addition changes in left ventricular ejection fraction after several months of beta-blocker treatment appears to have predictive value for survival. This beneficial effect of beta-blockade in chronic heart failure needs to be assessed further. The presumed benefit of beta-blockade with betaxolol (CAS 63659-18-7), a highly selective beta-blocker with long duration of action in chronic heart failure (CHF) will be assessed in BETACAR, a comparative study versus carvedilol (CAS 72956-09-3). The design of this study is provided in this article.
