**10. Conclusions**

The diagnosis of HF in an outpatient setting is a difficult task. First, it is necessary to determine the clinical probability of HF by the features of manifestations, their dynamics, and risk factors. Then, to clarify the presence of diseases that could explain the symptoms, to assess the EF. In the absence of a reduction in EF ≤40%, it is required to calculate the HFA-PEFF Score (a more complex and expensive variant) or H2FPEF score (a cheaper and more available option, but less precise). If tissue Doppler imaging is not available, a torasemide test should be used for differential diagnosis of dyspnea.

In any case, it is impossible to allow the risk of performing a patient's examination to exceed the benefit of the information received. The examination should be sufficient to make an adequate decision about the treatment of the patient, and not be the goal itself.
