Myocardial strain is regulated by cardiac preload in the early stage of sepsis.

ABSTRACT:

Background

Owing to a lack of data, this study aimed to explore the effect of cardiac preload on myocardial strain in patients with sepsis.

Methods

A total of 70 patients with sepsis in intensive care unit (ICU) of a tertiary teaching hospital in China from January 2018 to July 2019 and underwent transthoracic echocardiography were enrolled. Echocardiographic data were recorded at ICU admission and 24 h later. Patients were assigned to low left ventricular end-diastolic volume index (LVEDVI) and normal LVEDVI groups. We assessed the impact of preload on myocardial strain between the groups and analyzed the correlation of echocardiographic parameters under different preload conditions.

Results

Thirty-seven patients (53%) had a low LVEDVI and 33 (47%) a normal LVEDVI. T
