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 R 2 of 0.0024 and R 2 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.

Highlights
The prevalence of heart failure is estimated to reach 1-2% of the adult population in developing countries and is mainly experienced by those aged 70 years (Owan, 2006)
The results of the analysis showed the comparison of the use of echocardiography and Non-invasive Cardiac System (NiCAS) in Cardiac Index (CI) measurements to predict acute kidney failure in patients with heart failure according to inclusion criteria
This study revealed the suitability of CI measurements between NiCAS and echocardiography in 23 samples (59%) and the same result was found in research by Chen (2014) that there was a correlation between CI measurement results using ICG and echocardiography (P
Summary
The prevalence of heart failure is estimated to reach 1-2% of the adult population in developing countries and is mainly experienced by those aged 70 years (Owan, 2006). Heart failure itself can be accompanied by several diseases including renal insufficiency or kidney failure. Decreased filtration rate of the renal glomerulus in heart failure patients is influenced by factors such as low Cardiac Output (CO), increased intra-abdominal pressure, and increased venous pressure (Liu, 2008). CO indexed by body surface area of Cardiac Index (CI) is an important clinical parameter and is used to assess patients with heart failure and patients with critical illness. Decreased CO and CI in patients with heart failure indicates the inadequacy of tissue perfusion, including perfusion to the kidneys, which triggers acute kidney injury (AKI)
