Acute cardiac care & resuscitationCohort study
Right ventricular free-wall strain-based risk stratification for temporary mechanical circulatory support in cardiogenic shock
- single-centre retrospective study
Authors' conclusion
Integration of RV FWLS with clinical parameters may improve early risk stratification in CS.
Study context
- Population
- Patients admitted with cardiogenic shock (CS) with transthoracic echocardiography within 24 h of CS diagnosis and prior to mechanical circulatory support (MCS) implantation, January 2023 to December 202531 (34%) required temporary MCS
- Participants
- Ninety-two patients
- Exposure
- Severe right ventricular (RV) FWLS impairment and temporary MCS use
- Outcome
- Temporary MCS implantation
- Follow-up
- During hospitalization
Main finding
As reported in the abstract
Odds ratio
10.49
95% CI 3.72–29.59
Severe RV FWLS impairment (<11%)
OR 10.49 (95% CI 3.72–29.59)
Observational data: associations, not effects.
Secondary outcomes
