[A novel agent in the treatment of heart failure with depressed systolic function].

INTRODUCTION

A review is presented on the evolution of the pharmacological treatment of heart failure (HF) in the last 25 years, from the concept of treatment with vasodilators to the blocking or inhibition of the renin angiotensin aldosterone system. Beta-adrenergic inhibition and its important contribution in the reduction of morbidity and mortality due to HF will be discussed along with the role of the natriuretic peptides. One of the most important studies in the cardiology area, and specifically in the management of HF, is presented, in which an approach is demonstrated of the modulator of the neurohumoral systems that are activated in these patients.

OBJECTIVES

HF is the final stage of most cardiovascular diseases, and has a high rate of hospital admission, as well as cardiovascular morbidity and mortality. Therefore, there is constant interest in the need to find an innovative therapeutic agent that significantly reduces these complications and that improves the quality of life of those who suffer from it.

METHODS

A description will be presented of the PARADIGM-HF Clinical Trial using a sacubitril/valsartán compound for the management of HF with a modulating mechanism different from the concept of a deleterious system blocker that is activated when a patient has symptoms and signs of heart failure.

CONCLUSIONS

Death due to cardiovascular causes, or hospital admission due to heart failure (the primary endpoint) occurred in 914 patients (21.8%) in the Sacubitril / valsartán group, and 1117 patients (26.5%) in the enalapril group (risk ratio in the sacubitril / valsartán group, 0.80, with a 95% confidence interval [CI]: 0.73 to 0.87, P<0.001 [exact P= 4.0 × 10 - 7]). Of the patients receiving sacubitril / valsartán, 537 (12.8%) were hospitalised due to heart failure, compared with 658 patients (15.6%) receiving enalapril (hazard ratio 0.79, 95% CI: 0.71 to 0.89, P<.001). A total of 711 patients (17.0%) in the sacubitril / valsartán group, and 835 patients (19.8%) in the enalapril group, died (all-cause death rate, 0.84, 95% CI: 0.76 to 0.93, P<.001).
