Tratamento da insuficiência cardíaca com fração de ejeção normal

Abstract

Different from heart failure with reduced ejection fraction (HFREF), for which large studies have demonstrated the effectiveness of drug treatment to improve morbidity and mortality, no treatment study has shown definitive results in patients with heart failure with normal ejection fraction (HFNEF). HFNEF is more prevalent in women and the elderly and it is associated with multiple comorbidities. Although the optimum treatment has yet to be defined, the control of arterial hypertension and decreased fluid overload are important measures to control the syndrome. In Brazil, the recommendations for the treatment of HF are based on the Review of the II Directives of the Brazilian Society of Cardiology for the diagnosis and treatment of Heart Failure - 2002. However, none of the recommendations is specific for patients with HFNEF, as they are based on general measures proposed by specialists. This review aims at demonstrating the scientific evidence from recent clinical trials in HFNEF and future perspectives in terms of new medications.
