Comparing the Use of Echocardiography and Non-Invasive Cardiac System in Measuring the Cardiac Index to Predict Acute Kidney Failure in Patients with Heart Failure

Abstract

The prevalence of heart failure is 1-2% of the adult population in developing countries. Decreased kidney function in these patients is influenced by several factors including low Cardiac Output (CO) (Liu, 2008). Cardiac Index (CI) is an important parameter for assessing patients with heart failure since a decrease in CI in heart failure patients indicates the inadequacy of tissue perfusion, including the kidney, which triggers Acute Kidney Injury (AKI). Thus, it is necessary to study hemodynamic surveillance in patients with heart failure both by using echocardiography which is routinely carried out in the Emergency Room (IGD) of the Saiful Anwar Public Hospital (RSSA) as well as a Non-invasive Cardiac System (NiCAS) monitoring tool to predict AKI in patients with heart failure.

Methods: Analytical observations were done in 39 patients with heart failure in the Emergency Room of RSSA to determine the suitability of NiCAS and echocardiography in measuring CI to predict acute kidney failure in these patients.

Results: The suitability of CI measurements on NiCAS and echocardiography was obtained in 23 samples (59%) (p = 0.175). Creatinine suitability and Echocardiography CI R² were 0.0068. Creatinine suitability and NiCAS CI were tested at 12^th hour, since the patient was hospitalized, under linearity conditions resulting in R² of 0.0024 and R² 0.0287.

Conclusion: Measurement of NiCAS matches measurement with echocardiography in measuring Cardiac Index. However, neither NiCAS nor Echocardiography does not a match in predicting acute kidney failure in patients with acute heart failure.
