Intracoronary Stenting Myocardial Fractional Flow Reserve To Predict Cardiac Events

Objective To determine the predictive value of myocardial fractional flow reserve (FFRmyo) on major adverse cardiac events (MACE) in patients with stable angina after coronary artery stenting.Methods Of patients with stable angina admitted to our department from July 2003 to September 2003, 79 patients with single vessel disease were enrolled into the present study. FFRmyo and angiographic findings by quantity coronary angiography (QCA) were calculated before and immediately after coronary artery stenting. Incidence of MACE was recorded during 6 months follow-up. Multistep logistic regression analysis was managed to determine coronary risk factors, FFRmyo and indexes by QCA.Results Of 79 patients, 76 patients completed clinical follow-up within 6 months. MACE was identified in 14 patients (18.4%), 10 of 14 patients experienced re-angina (13.1%), revascularization of target segment was needed in 4 patients (5.3%). By multistep logistic regress analysis, FFRmyo...
