Article Synopsis
- The Shock Academic Research Consortium (SHARC) created standardized definitions for cardiogenic shock (CS) to improve classification in clinical settings and studies.
- A study using these definitions observed a total of 8,974 patients, finding that 65% had isolated CS, with significant variations in causes such as acute myocardial infarction and heart failure.
- Results indicated that patients with mixed CS had the highest mortality rate (48%), while acute-on-chronic heart failure presented the lowest (25%), highlighting the need for targeted treatment strategies based on CS subtypes.
Article Synopsis
- The study investigates current management practices for patients using temporary mechanical circulatory support (tMCS) devices like intra-aortic balloon pumps and Impella in North American cardiac intensive care units.
- An online survey was conducted, with a response rate of 84% from 37 centers, focusing on hemodynamic monitoring, hemocompatibility, and weaning/removal of the devices.
- Results showed significant variability in how these practices are implemented, indicating a need for standardized guidelines to improve patient outcomes with tMCS.
Background: Associations of early changes in vasoactive support with cardiogenic shock (CS) mortality remain incompletely defined.
Methods: The Critical Care Cardiology Trials Network is a multicenter registry of cardiac intensive care units. Patients admitted with CS (2018-2023) had vasoactive dosing assessed at 4 and 24 hours from cardiac intensive care unit admission and quantified by the vasoactive-inotropic score (VIS).
Article Synopsis
- A study was conducted to assess the clinical characteristics and outcomes of patients in a cardiac intensive care unit (CICU) who were referred for cardiac surgery from 2017 to 2020 across 29 medical centers.
- Out of 10,321 CICU admissions, 887 patients (8.6%) underwent various types of cardiac surgery, with common admission issues including shock and respiratory insufficiency.
- The overall in-hospital mortality rate for these CICU patients was 11.7%, but those who had surgery had a lower rate of 9.1%, suggesting that clinicians effectively managed higher acuity patients with acceptable risks during surgery.
