Background
Impaired global coronary flow reserve (g-CFR) evaluated by phase-contrast cine cardiovascular magnetic resonance (PC-CMR) has been reported to be associated with worse outcomes in patients with cardiovascular disease.
Purpose
This study aimed to evaluate the prognostic value of g-CFR improvement evaluated by PC-CMR in patients with chronic coronary syndrome (CCS).
Methods
A total of 320 patients with CCS who underwent pre- and post-PCI PC-CMR measurements and stress perfusion CMR were followed-up to determine the predictors of major adverse cardiovascular events (MACE). The association between CMR variables including changes in G-CFR after PCI and MACE (cardiac death, nonfatal myocardial infarction, hospitalization for heart failure, or ischemic stroke) was investigated.
Results
G-CFR improvement was observed in 162 (50.6%) and MACE occurred in 26 (8.1%) during follow-up (2.5 year, 1.3-4.0). G-CFR improvement was significantly associated with lower pre-PCI G-CFR (p |
