Overview

In the case of cardiogenic shock, the early mortality rate is the highest compared to other types of shock, but it is characterized by a good prognosis and quality of life after recovery, so monitoring the treatment progress is very important to identify the patient's prognosis. However, there are few studies specifically reported on hemodynamic monitoring and prognosis of cardiogenic shock. In addition, as mechanical circulatory support devices are in the spotlight, studies on their effects and safety are starting, but studies on cardiogenic shock are often limited to patients with myocardial infarction.

This study is a prospective and retrospective cohort observational study, we aim to identify factors that can improve prognosis, including various drug treatments, diagnostic techniques, and mechanical circulatory support device by investigating the treatment status and clinical outcomes of patients with cardiogenic shock hospitalized in cardiovascular critical care unit. In addition, the purpose of this study is to investigate the association between the prognosis of patients with cardiogenic shock and the presence of a specialist resident during regular work hours to clarify the role and necessity of a resident specialist in the cardiovascular intensive care unit.

Furthermore, by predicting and treating the clinical course of patients with cardiogenic shock at an early stage, the aim is to reduce the mortality rate and improve the patients' ability to perform daily activities.
