Abstract

Natriuretic peptides (NPs) play a significant role in the pathophysiology of heart failure (HF) and are considered reliable diagnostic and prognostic indicators of congestive HF. Pulmonary congestion in HF patients leads to clinical deterioration and hospitalizations. It remains an important aspect to address the management and treatment tailoring in HF patients. However, the role of NP-guided therapy remains debatable due to contrasting reports in the literature. Current guidelines do not recommend the use of NP-guided therapy in the treatment monitoring of HF. Therefore, there is an urgent need to identify reliable markers for treatment monitoring in congestive HF. For early detection of congestion, a technology-based approach to monitor pulmonary hemodynamics and absolute lung fluid measurement is found to be effective in guiding treatment. Remote dielectric sensing technology is one such non-invasive approach that measures pulmonary fluid levels in the lungs which results in reduced hospitalization and re-admission rate in HF patients. In this review, we summarized the role of natriuretic peptides and the need for a reliable tool to assess pulmonary congestion for treatment monitoring in HF.
