  • Title: Beta blocker therapy for chronic heart failure.
    Author: Ramahi TM.
    Journal: Am Fam Physician; 2000 Nov 15; 62(10):2267-74. PubMed ID: 11126853.
    Abstract:
    Recent studies have shown that beta blocker therapy improves survival and reduces hospitalizations in patients who have chronic heart failure and left ventricular systolic dysfunction, the majority of whom are under the management of primary care physicians. Appropriate patient selection is essential to the successful initiation of beta blocker therapy. Candidates should be stable in New York Heart Association functional class II or III. Patients with severe heart failure, especially inotrope-dependent and hospitalized patients, and those with hypotension, bradycardia or higher than first-degree heart block are not considered appropriate candidates for beta blocker therapy. Optimal diuresis is essential for maximal tolerability. Beta blockers should be started at the lowest dose, with the dose increased every two to four weeks until the target dose or highest tolerated dose is reached. Close monitoring allows for the detection and appropriate management of side effects, such as hypotension, bradycardia and increased congestion. The treatment goal is long-term improvement of prognosis, rather than immediate improvement of symptoms.
