Abstract

ALVAREZ ROCHA, Pablo  and  GRUPO UMIC et al. Ten years of experience in beta-blockers prescription in the Multidisciplinary Heart Failure Unit of the Hospital de Clinicas of Montevideo. Rev.Urug.Cardiol. [online]. 2015, vol.30, n.1, pp.19-31. ISSN 1688-0420.

Introduction: the benefits in symptomatology and survival that prescribing and optimizing beta blockers through multidisciplinary units has in acute heart failure (AHF) can be compromised by peculiarities in access, adherence and drug tolerance. Objective: the analytical observation in the prescription of beta blockers with the intention to treat at the UMIC cohort during a ten-year period at the Hospital de Clìnicas (The University Hospital) in Montevideo. Material and methods: an open cohort, prospective, observation-based, analytical monitoring; inclusion: systolic dysfunction, age > 18 years, left ventricular ejection fraction< 40%. Prescription: a priori and posteriori b-blockade inclusion and patterns according to the number of prescribed molecules.Prescribed doses, initial heart rate and follow-up, incidence of death, survival and cumulative incidence of events are determined. Outcome: 412 patients are included, 61,8±12 years, 65,5% male, monitoring 1.157 person-years, median: 2,42 years. Prevalence: a priori b-blockade 69,8%,  b-blockade at trial break 93,2%, patterns of one molecule 71,8%, 0 molecule 6,8%. Survivals up to 5 years significantly longer with b-blockade (82% vs. 48%) prescription, patterns 1 vs. 2 vs. 0 (80%, 85% vs. 48%) and with pattern 1 prescribing Bisoprolol (84%) rather than Carvedilol (68%). In 70% prescribed doses were lower than the ones in the protocol and a difference in heart rate response according to prescribed molecules was found. Conclusions: in ten years of operation of UMIC benefits in beta blockers prescription, and a bigger prevalence in prescription and longer survival are confirmed, difficulties in fulfilling the indication prescribed were verified.
