Popis: Background. Remote ischemic conditioning (RIC) confers protection against myocardial ischemia-reperfusion injury and may modulate coronary blood flow. We investigated whether RIC affects resting myocardial perfusion (MP) in patients with suspected ischemic coronary artery disease by quantitative MP imaging.Methods and Results. We included 49 patients with suspected ischemic coronary artery disease. Resting MP was quantified by 82 Rubidium positron emission tomography/computed tomography (Rb-82-PET/CT) imaging before and after RIC, performed as four cycles of 5 minutes upper arm ischemia and reperfusion. Subsequent adenosine Rb-82-PET/CT stress-imaging identified non-ischemic and reversibly ischemic myocardial segments. MicroRNA-144 plasma levels were measured before and after RIC. Normalized for rate pressure product, RIC did not affect MP globally (P = .64) or in non-ischemic myocardial segmene in MPts (P = .58) but decreased MP in reversibly ischemic myocardial segments (-0.11 mL/min/g decreas following RIC; 95% CI -0.17 to -0.06, P Conclusions. RIC did not substantially affect resting MP globally or in non-ischemic and reversibly ischemic myocardial territories in patients with suspected ischemic coronary artery disease.
