Factors associated with symptom-to-surgery time in patients undergoing surgical repair for acute type A aortic dissection: an exploratory analysis from a prospective cohort study.

ABSTRACT:

Abstract

Objectives

The primary objective of this study was to investigate perioperative factors associated with symptom-to-surgery (STS) time in patients diagnosed with hyper-acute aortic dissection (AAD). The secondary objective was to develop a causal model to understand the relationship between STS times and hospital mortality in this population.

Design

Prospective cohort study.

Setting

Exploratory analysis of a national audit conducted by the Association of Cardiothoracic Anaesthesia and Critical Care.

Participants

From a total of 270 participants diagnosed with AAD with an STS time <72 hours, 218 were included in the multivariate analysis, after excluding 52 participants with missing covariates.

Main outcome measures

STS time, measured in h
