Heart Failure With Reduced Ejection Fraction
Conditions
Brief summary
Sacubitril-Valsartan reduced heart failure hospitalizations and cardiovascular mortality compared to enelapril in chronic heart failure. Furthermore, quality of life is improved. The decrease of NT-proBNP levels during Sacubitril-Valsartan treatment is associated with reverse left ventricular remodeling and improved left ventricular systolic function. However, the underlying mechanisms that contribute to these symptomatic and prognostic benefits are largely unknown. The aim of this study is to evaluate left ventricular hemodynamics in patients treated with Sacubitril-Valsartan using non-invasive pressure-volume analysis.
