Introduction:

The term "di novo" heart failure refers to patients without a previous diagnosis of this disease. The review of this issue comes from a real problem, since a group of patients attend secondary care without a previous diagnosis of heart failure and also have in advanced stages.

Objective:

The objective is to provide a clue that facilitates the early diagnosis of heart failure.

Methods:

A bibliographic search was carried out in the following databases: Pubmed, SciELO, ESBCO, Cochrane and BVS, as well as in different medical websites for three months (February 1, 2021 to May 31, 2021).

Conclusions:

The early diagnosis of heart failure will allow us to reduce the number of patients who arrive at Secondary Care without a previous diagnosis. There are classifications that identify early stages of the disease, being in our opinion the ACC / AHA classification the one that should carry the most weight. In primary care this can be a challenge if diagnostic tests such as echocardiography are not used. Dosification of serum levels of type B natriuretic peptide (BNP) and the N-terminal fragment of its protohormone (N-terminal BNP) is very useful. This biomarker should be accessible in outpatient clinics for patients with clinical suspicion of "di novo" heart failure.
