Noninvasive Assessment of Pulmonary Fluid Levels by Remote Dielectric Sensing Technology to Improve Cardiac InsUfficieney During Ischemia-Reperfusion and Clinical Outcomes in MyocArdiaL Infarction

Overview

To explore whether a ReDS-guided strategy for AMI patients with cardiac insufficiency following coronary flow reperfusion is superior to routine care for improving outcomes.

The remote dielectric sensing (ReDS) system is a non-invasive medical device that emits a low-power electromagnetic signal through the chest and lungs, which can accurately measure changes in lung fluid concentration. Previous studies suggest that ReDS-guided management may have the potential role in the diagnosis and treatment of acute heart failure (AHF): (1) Assessment of real-time volume status: Patients with AHF are often accompanied by volume overload, especially pulmonary congestion, which is one of the main risk factors for readmission; (2) Establishment of treatment strategy: The ReDS-SAFE HF study showed that the AHF treatment strategy based on the ReDS measurement could significantly reduce the readmission rate and the clinical outcomes after discharge; (3) Determine time to discharge: The study ReDS-SAFE HF also suggests ReDS measurement can aid physicians to determine the appropriate time to discharge by monitoring changes in the volume of lung fluid, which can relatively avoid the risk of early or late discharge. Acute myocardial stunning and injury combined with cardiac insufficiency is one common complication of acute myocardial infarction (AMI), the large infarcted area of the left ventricular anterior wall can lead to heart pump failure, which will cause pulmonary edema and acute decompensated heart failure (ADHF) in the long-term recovery. Although cardiomyocytes do not completely lose their activity following the cardiac circulatory reperfusion, it still requires a long period for the myocardium to restore normal function, which closely related to the basal myocardial status, number of coronary lesions, area of myocardial infarction, and time of reperfusion. Long-time loss of myocardial activity then results in irreversible myocardial remodeling of patients in and seriously impacts the life quality of life of AMI patients. Therefore, it is particularly important to find an effective convenient management scheme to improve cardiac insufficiency following ischemic reperfusion in AMI patients. Among these patients, acute ischemic myocardium and cardiac dysfunction could simultaneously induce rapid adaptive alterations in lung fluid, which provides an indicative parameter in the clinical and could be well-determined by the ReDS devices. This study sought to explore whether a ReDS-guided strategy for AMI patients with cardiac insufficiency following coronary flow reperfusion is superior to routine care for improving outcomes.
