Study Summary

The goal of this observational study is to evaluate whether a new integrated mathematical model can improve the accuracy of diagnosing septic cardiomyopathy and predicting clinical outcomes in adult patients with suspected septic cardiomyopathy. The study aims to determine whether the integrated mathematical model enhances diagnostic accuracy and improves the prediction of clinical outcomes in these patients.

Study Description

This multicenter, prospective observational study will enrol adult patients treated for sepsis or septic shock in the intensive care unit (ICU). Eligible patients will be identified based on predefined inclusion and exclusion criteria and enrolled in the study after obtaining informed consent. The primary transthoracic echocardiography will be performed within 48 hours of enrollment to gather detailed echocardiographic data, while key hemodynamic measurements will be recorded simultaneously.

A second transthoracic echocardiography will be conducted within 10 days of the initial evaluation. This follow-up assessment will occur during continued ICU care after discontinuation of vasopressor therapy or during hospitalization in the general ward, depending on the patient's clinical progression. The echocardiographic and hemodynamic parameters from both the initial and follow-up evaluations will be input into a mathematical formula designed to integrate these data into a single cardiovascular estimate. This integrated model will then be used to assess its ability to predict patient outcomes.

Following hospital discharge, patients will be followed for up to one year. During this period, a long-term follow-up assessment will be conducted, during which patients will complete the SF-36 quality of life questionnaire. This follow-up will assess patients' overall health, functional status, frequency of healthcare visits, and need for nursing care. These data will provide insights into the long-term impact of sepsis and septic cardiomyopathy on survivors beyond the acute phase of their illness.

This study will evaluate whether the use of an integrated model that combines clinical parameters with echocardiographic measurements can improve the accuracy of diagnosing septic cardiomyopathy and provide valuable predictions of clinical outcomes. Additionally, the study will assess the course of septic cardiomyopathy and its impact on one-year follow-up outcomes, including patient quality of life. A broadly applicable diagnostic approach could allow for timely treatment adjustments, reduce the burden of sepsis-related complications, and improve overall patient outcomes.
