[en] The introduction of basic treatment for heart failure dates to the late 1990s. Since that time, apart from a few new developments reserved for selected patients, there has been little progress. During these years, the epidemiology of the disease has evolved. The number of patients is constantly increasing and the prognosis is often darker than most oncological pathologies. With the arrival of the sacubitril/valsartan combination, Entresto®, a new therapeutic class has emerged. It has shown a significant reduction in mortality and hospitalizations for heart failure. The additional benefits to be expected from this molecule are still being evaluated. Significant positive remodeling seems to be a reality for many patients. This spectacular advance, however, is not the final solution. In addition, patients with preserved heart failure do not seem to benefit the same from this molecule. Other advances are being assessed. Sacubitril/valsartan is the first revolution, perhaps, in a long series.
