Correlation between CT-derived fractional flow reserve and myocardial strain in ischemic heart disease patients with single coronary artery stenosis assessed based on CCTA.

ABSTRACT:

Purpose

We aimed to investigate the correlation between CT-derived fractional flow reserve (CTFFR) and myocardial strain in patients with single coronary artery stenosis and to investigate the diagnostic value of CTFFR in identifying impaired myocardial strain.

Methods

We selected 89 patients, categorized into three groups based on the affected coronary artery: 36 with left anterior descending (LAD), 23 with left circumflex (LCX), and 30 with right coronary artery (RCA) stenosis, along with 25 healthy controls. We investigated correlations between CTFFR and both global and regional myocardial strain parameters. Additionally, we assessed the ability of the CTFFR to detect impaired myocardial strain in these patients.

Results

In this study, no significant difference was
