Minimum Mean Arterial Pressure and Associated Mortality Outcomes in the Cardiac Intensive Care Unit.

ABSTRACT:

Background

Hypotension is associated with increased mortality in critical care settings; limited data exist on the minimum mean arterial pressure (minMAP) in cardiac critical illness.

Objectives

The objective of the study was to investigate the prognostic value of the minMAP within the first 24 hours of admission to cardiac intensive care unit (CICU).

Methods

This retrospective, single-center study included adult CICU patients (2007-2018). The minMAP within the first 24 hours was the exposure of interest. Patients were categorized into four minMAP groups using a classification and regression tree model. Primary outcome was in-hospital mortality; secondary, 30-day mortality. Multivariable logistic and Cox regression models were adjusted for confounders.
