Introduction Sepsis is a severe medical condition affecting millions of people each year. The worldwide average incidence of sepsis ranges from 56 to 91 cases per 100,000 persons, with a documented mortality rate of 30%. Myocardial dysfunction is a common feature of sepsis. Cardiac failure in septic shock is a pivotal factor in multiple organ dysfunction and a major contributor to death. A large number of studies have assessed cardiac function in sepsis patients using various metrics, including cardiac biomarkers, left ventricular (LV) systolic and diastolic function, and right ventricular (RV) performance by echocardiography. The present study is conducted to find out the significance of echocardiography in prognosis of patients with septic shock presenting to ED in a tertiary care hospital. Objectives 1. To study the significance of echocardiography in prognosis of patients with septic shock presenting to ED in a tertiary care hospital. Methodology A prospective study was conducted between January 2023 to January 2025 among 82 patients admitted with features suggestive of septic shock in Emergency medicine department at at IQRAA International Hospital, Calicut. Transthoracic Echocardiography was performed to assess cardiac function. The data collected was entered into Microsoft Excel 2019 and analysed using SPSS version 26. Results The majority of the participants in the current study belonged to the age group of >50 years (70.7%) followed by 41-50 years (23.2%) and 58.5% participants were males and 41.5% participants were females. Urosepsis (50%) was the most common diagnosed as urosepsis followed by pneumonia (29.3%), cellulitis (6.1%). ECG findings of the study participants showed 16 (19.5%) having sinus tachycardia while remaining 66 (80.5%) participants had normal sinus rhythm. 25.6% participants had mild LV systolic dysfunction; 19.5% participants had moderate LV systolic dysfunction while 2.4% participants had severe LV 3 systolic dysfunction. 73.2% participants had normal RV systolic function while 26.8% had RV systolic dysfunction. RWMA was present in 23.2% participants. Ventilatory support was required for 61% study participants. 54.9% participants in the current study survived while 45.1% participants succumbed. Majority of the participants with normal LV systolic function (76.7%) had also survived while all the patients with severe LV systolic dysfunction died. Mortality was seen in 81.8% of the participants with RV systolic dysfunction and 35% of the participants with normal RV systolic function. Conclusion Our prospective observational research assessed cardiac function using echocardiography in patients with septic shock, revealing that right ventricular systolic dysfunction and left ventricular systolic dysfunction are significantly frequent and serve as independent predictors of mortality. The systolic dysfunction of both left and right ventricles in persons displaying signs of septic shock was significantly associated with prognosis. Additional examination of the prognostic significance and therapeutic use of early echocardiography in septic patients is crucial for achieving a definitive and corroborative diagnosis.
