Overview

This trial is a single-center, open-label, randomized study designed to assess the impact of a rapid up-titration of Guideline-Directed Medical Therapy (GDMT) on heart failure with reduced ejection fraction (HFrEF) patients following transcatheter valve interventions. The study focuses on the efficacy of intensive treatment in decreasing NT-proBNP levels and improving patient outcomes, including survival rates and quality of life over a six-month period. Patients are closely monitored using both Point-of-Care technology and hospital-based assessments, with the goal of enhancing GDMT adjustments. This approach is compared to standard care to determine its potential benefits in the management of HFrEF post-valve intervention.

Heart valve disease, with a current prevalence of 2.5% that rises with age, has been described as "the next cardiac epidemic", and is projected to double by 2040 and triple by 2060, paralleling population aging. The period during and immediately after hospitalization for transcatheter valve intervention (TVI) in HFrEF patients (LVEF ≤ 40%) represents a "vulnerable phase" characterized by a high risk of death and re-hospitalization for acute HF. A study from the TVI registry demonstrated that, among 12.182 patients treated with TAVR in the United States, the rate of HF readmission at 1 year was 14.3% and the 1-year overall mortality was 23.7%. Moreover, the CHOICE-MI registry demonstrated that the primary combined endpoint of all-cause mortality or HF hospitalization at 1 year occurred in 39.2% of the Transcatheter mitral valve implantation (TMVI) patients, and in 28% in those TMVI-ineligible who undergoing bailout-TEER. Recently, the STRONG-HF trial demonstrated that rapid, intensive up-titration of guideline-directed therapy, coupled with close post-discharge follow-up, significantly enhances life quality and reduces 180-day mortality and heart failure readmission rates versus usual care. Previous studies have additionally shown that a decrease in NT-proBNP levels during hospitalization for acute HF is associated with improved survival and reduced readmission rates. Patients whose NT-proBNP levels decrease by at least 30% tend to have a better prognosis compared to those with no significant change or an increase in levels. This suggests that a meaningful decrease in NT-proBNP levels can indicate successful response to HF treatment. Consequently, guiding HF therapy based on NT-proBNP levels can potentially improve clinical outcomes. For instance, adjusting medications to achieve a target NT-proBNP level may result in better control of HF symptoms and a lower risk of hospital readmission and mortality. This approach emphasizes the role of NT-proBNP as not just a diagnostic and prognostic tool but also as a therapeutic target in HF management. Overall, the use of NT-proBNP monitoring to guide medical therapy in HF patients supports a more personalized treatment strategy, potentially leading to rapid and effective decongestion, optimized therapy, and improved patient outcomes. Hence, the primary objective of this study is to assess the impact of rapid up-titration of Guideline-Directed Medical Therapy (GDMT) in patients with HFrEF undergoing transcatheter valvular intervention, supplemented by close follow-up visits and NT-proBNP measurements, using a hierarchical composite endpoint, which prioritize (1) all-cause mortality, (2) number of hospitalizations for heart failure, and (3) improvement in NT-proBNP, defined as a decrease of at least 30% from the baseline value.
