Chronic Kidney Disease, Hyperkalemia and Echocardiographic Changes

Recruiting

• Conditions: Chronic Kidney Disease (CKD); Hyperkalemia; Hemodialysis

• Registration Number: NCT06635590
• Lead Sponsor: Saglik Bilimleri Universitesi

Brief Summary

Patients with CKD ( eGFR \< \<60 mL/min/1,73 m2) presenting to emergency department with isolated hyperkalemia will be study population. Pre and post treatment ECG and echocardiographic findings will be recorded. Investigator will not intervene with the treatment decision of responsible physician and will not delay any intervetion or treatment for the sake of study.

Data will be compared in terms of ECHO and ECG findings depending on hyperkalemia level and response to treatment.

Detailed Description

In this study, the ECG and echocardiography (ECHO) findings in patients with chronic kidney failure who present to the Etlik City Hospital Emergency Medicine Department will be recorded and compared with literature. Echocardiography is a rapid, reliable, and non-invasive examination widely used by physicians for the monitoring of critically ill patients in emergency departments and intensive care units worldwide.

For patients with known chronic kidney failure brought to the emergency department, a blood sample (blood gas and/or biochemistry) will be taken for potassium measurement. Subsequently, an ECG, which is a quick and non-invasive test, will be performed, followed by an ECHO, also a quick and non-invasive test, conducted by an experienced physician. The physician performing the ECHO will not be involved in the treatment process. ECG and ECHO findings will be recorded and compared before and after treatment. Patient mortality will be monitored at 24 hours, 7 days, and 30 days, and other causes of mortality will be excluded. The relationship between ECG and ECHO findings and mortality will be statistically investigated.

Based on the premise that hyperkalemia can cause cardiac arrest during diastole, it is hypothesized that there may be right ventricular enlargement in patients with ECG findings indicative of hyperkalemia. In animal studies, echocardiography results during resuscitation have shown right ventricular enlargement in animals with hyperkalemia. Based on this information, we believe that echocardiography findings in hyperkalemic patients may be associated with mortality, and that the combined use of echocardiography and ECG may be effective in predicting mortality
