RESUMO
Resumen Introducción: Se revisará la evolución del tratamiento farmacológico de la insuficiencia cardiaca (IC) en los últimos 25 an˜os, desde el concepto de tratamiento con vasodilatadores, pasando por el bloqueo o inhibición del sistema renina-angiotensina-aldosterona y la inhibición betaadrenérgica y su importante contribución en la disminución de la morbimortalidad por IC, el papel de los péptidos natriuréticos y, finalmente, se conocerá uno de los estudios más importantes en el área cardiológica y específicamente en el manejo de la IC, en el cual se demuestra un enfoque modulador de los sistemas neuro humorales que se activan en estos pacientes. Objetivos: La IC constituye la etapa final de la mayoría de las enfermedades cardiovasculares, con una alta tasa de hospitalización y de morbimortalidad cardiovascular, siendo, por lo tanto, de interés constante la necesidad de encontrar un agente terapéutico innovador que disminuya significativamente estas complicaciones y también que mejore la calidad de vida de los que la presentan. Metodología: Se realizará una descripción del PARADIGM-HF Clinical Trial, que utilizó un compuesto sacubitrilo/valsartán para el manejo de la IC con un mecanismo modulador diferente del concepto de bloqueador de sistemas deletéreos que se activan cuando un paciente presenta síntomas y signos de IC. Conclusiones: La muerte por causas cardiovasculares u hospitalización por IC (el punto final primario) se produjo en 914 pacientes (21.8%) en el grupo sacubitrilo/valsartán y 1,117 pacientes (26.5%) en el grupo de enalapril (razón de riesgo en el grupo sacubitrilo/valsartán, 0.80; intervalo de confianza (IC) del 95%: 0.73 a 0.87; p < 0.001 (exacta p = 4.0 × 10 - 7)). De los pacientes que recibieron sacubitrilo/valsartán, 537 (12.8%) fueron hospitalizados por IC, en comparación con los 658 pacientes (15.6%) que recibieron enalapril (razón de riesgo, 0.79; IC del 95%, 0.71 a 0.89; p < 0.001). Un total de 711 pacientes (17.0%) en el grupo sacubitrilo/valsartán y 835 pacientes (19.8%) en el grupo de enalapril murió (razón de riesgo de muerte por cualquier causa, 0.84; IC del 95%, 0.76 a la 0.93; p < 0.001).
Abstract 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)
