Outcome of patients with low ejection fraction undergoing coronary artery bypass grafting: renal function and mortality after 3.8 years.

abstract：:Digital vasospastic phenomena have been reported to result from use of nonselective and cardioselective beta-adrenoreceptor-blocking drugs. The effects of 80 mg/day propranolol and 100 mg/day metoprolol on finger hemodynamics and clinical responses were compared with those of placebo in 16 patients with Raynaud's phen...
