[Does treatment improve prognosis of heart failure with preserved ejection fraction?].

Heart failure with preserved ejection fraction (HF-PEF) represents half of all heart failure. Morbi-mortality for HF-PEF is similar to that of reduced ejection fraction HF (HF-REF). Diagnosis of HF-REF is difficult because of the lack of highly specific criteria. It is based on the presence of signs and symptoms of heart failure, associated with a preserved or moderately decreased left ventricular function, the absence of left ventricular dilatation, and the presence of relevant structural disease such as left ventricular hypertrophy. Despite the use of prognosis modifying drugs commonly used for HF-REF, no therapeutic strategy has been shown to reduce morbi-mortality of HF-PEF. Evidence based guidelines are limited. Management of HF-PEF therefore resides in treatment of high blood pressure and cardiac rate, that of comorbidities, and the use of diuretics in case of congestion.
