Insights
New devices aim to improve acute decompensated heart failure (HF) by targeting specific mechanisms like fluid removal and contractility. This review details novel device therapies and their current clinical trial results for heart failure management.
Area of Science:
- Cardiology
- Biomedical Engineering
- Medical Device Development
Background:
- Congestive heart failure (HF) presents significant challenges including hospitalization, morbidity, mortality, and costs.
- Current treatments for decompensated HF involve medications and mechanical cardiac support.
- Emerging devices offer new therapeutic avenues for acute HF decompensation, focusing on symptom relief and organ function recovery.
Purpose of the Study:
- To review a novel classification scheme for new device-based therapies in acute heart failure.
- To describe emerging medical devices designed for acute decompensated heart failure.
- To present the latest preclinical and clinical trial results for these innovative devices.
Main Methods:
- A proposed device-based classification scheme, DRI2P2S, categorizes therapies by mechanism (dilators, removers, inotropes, interstitials, pushers, pullers, selective).
- Review of current literature on preclinical models and clinical trials of new heart failure devices.
- Analysis of device mechanisms including increasing venous capacitance, sodium/water removal, enhancing contractility, lymph removal, and modulating renal pressures.
Main Results:
- The DRI2P2S classification provides a framework for understanding diverse new device mechanisms for acute HF.
- Preclinical and clinical data are emerging for devices targeting various aspects of HF pathophysiology.
- These devices show potential for improving heart and renal function in acute decompensated heart failure patients.
Conclusions:
- Novel device-based therapies are being developed for acute decompensated heart failure.
- The DRI2P2S classification aids in understanding and comparing these new therapeutic approaches.
- Further research and clinical trials are crucial to establish the efficacy and safety of these devices in managing heart failure.
Abstract:
Congestive heart failure (HF) is a devastating disease leading to prolonged hospitalization, high morbidity and mortality rates, and increased costs. Well-established treatments for decompensated or unstable patients include medications and mechanical cardiac support devices. For acute HF decompensation, new devices are being developed to help relieve symptoms and recover heart and renal function in these patients. A recent device-based classification scheme, collectively classified as DRI2P2S, has been proposed to better describe these new device-based therapies based on their mechanism: dilators (increase venous capacitance), removers (direct removal of sodium and water), inotropes (increase left ventricular contractility), interstitials (accelerate removal of lymph), pushers (increase renal arterial pressure), pullers (decrease renal venous pressure), and selective (selective intrarenal drug infusion). In this review, we describe the new class of medical devices with the most current results reported in preclinical models and clinical trials.
