Рossibility of using European (HFA-PEFF) and American (H2FPEF) algorithms for diagnosing heart failure with preserved ejection fraction in Russian clinical practice

This article focuses on the significance of a unified approach to diagnosing heart failure with preserved left ventricular ejection fraction (HFpEF). The key hemodynamic index of HFpEF is increased left ventricular filling pressure (LVFP) and its noninvasive marker, the E / e’ value obtained by tissue Doppler echocardiography (EchoCG). The modern verified algorithms for HFpEF diagnosis, HFA–PEFF and Н2FPEF, mandatorily take into account the E / e’ value. However, the routing use of these algorithms in the Russian practice may be complicated since even among “advanced” specialists who are interested in heart failure, 38% of the interviewed do not use or do not know how to use tissue Doppler EchoCG or the algorithm for diagnosing HFpEF with E / e’. In addition to the obvious way of overcoming this problem by equipping respective medical facilities with ultrasonic apparatuses with tissue Doppler EchoCG software and educating physicians, a possibility of using simplified HFA algorithm without the E / e’ value is being considered. However, such approach will inevitably lead to erroneous estimation of the probability of HFpEF and, at the best, to underestimation of this probability with ensuing mistakes in diagnosis and treatment. Simplifying the HFA–PEFF and H2FPEF algorithms by omitting one or more parameters is possible but this requires a special investigation to develop a new rating scale and actually a new algorithm, which, in turn, will require a new validation.
