Association of Shock Index with Echocardiographic Parameters in Cardiac Intensive Care Unit
Authors' conclusion
CICU patients with elevated SI have worse biventricular function and systemic hemodynamics, particularly decreased stroke volume and related calculated TTE parameters.
Study context
- Population
- Mayo Clinic cardiac intensive care unit (CICU) admissions 2007–2018 in sinus rhythm at the time of TTE58% acute coronary syndrome
- Participants
