The presence of AF was related to impaired CFR in both known and suspected CAD patients. Significant differences in CFR were found between controls and patients without AF (3.12 ± 0.52 vs.
CFR was significantly lower in patients with AF than in those without AF among all patients (n = 362) (2.45 ± 0.42 vs. CFR was calculated as CBF during adenosine triphosphate infusion divided by CBF at rest. Using a 1.5-T MR scanner and cardiac coils, blood flow of the coronary sinus (CBF) was quantified by PC cine MRI. We studied 362 patients with known or suspected coronary artery disease (CAD) and 20 age- and gender-matched control subjects. The present study aimed to evaluate the utility of PC cine MRI of the coronary sinus for assessing decreased CFR in patients with AF. Phase-contrast (PC) cine magnetic resonance imaging (MRI) of the coronary sinus serves as a non-invasive means of quantifying coronary flow reserve (CFR) without any radioactive tracer. Myocardial perfusion and perfusion reserve are diminished in patients with atrial fibrillation (AF).
