Haemodynamic and PCI characteristics of the coronary arteries and lesions studied.

Data are presented as mean (SD) for continuous variables. BMI, Body Mass index; Hb, Hemoglobin; SBP, Systolic Blood pressure; DBP, Diastolic Blood pressure; HR, Heart rate; LAD, Left Anterior Descending coronary artery; LCx, Left Circumflex coronary artery; OM1, First Obtuse Marginal branch; RCA, Right Coronary Artery. 3All lesions were graded according to the AHA lesion classification system [1]. 1, Bare Metal stent; 2, Drug eluting stent. Prox, proximal; Mid, mid segment (Table A). Individual participant hemodynamic and peri-procedural characteristics. AMI, Acute myocardial infarction; RCA, Right coronary artery; LAD, Left anterior descending coronary artery; LCx, Left circumflex coronary artery; cTnI, Cardiac Troponin I; FFR, Fractional Flow reserve; CFVR, Coronary Flow Velocity Reserve; EST, Exercise stress test; MPI, Sestamibi Myocardial Perfusion scan (Table B). Univariate linear regression analyses of FFR and CFVR with baseline haemodynamic and patient variables. HR, Heart Rate; SBP, Systolic Blood Pressure; DBP, Diastolic Blood Pressure; PP, Pulse Pressure; FFR, Fractional Flow reserve; CFVR, Coronary Flow Velocity Reserve; sFCW, systolic Forward travelling Compression Wave; dBEW, diastolic Backward travelling Expansion Wave (Table C). Univariate linear regression analyses of baseline (pre-PCI) sFCW and dBEW cumulative intensity with baseline haemodynamic and patient variables. HR, Heart Rate; SBP, Systolic Blood Pressure; DBP, Diastolic Blood Pressure; PP, Pulse Pressure; FFR, Fractional Flow reserve; CFVR, Coronary Flow Velocity Reserve; sFCW, systolic Forward travelling Compression Wave; dBEW, diastolic Backward travelling Expansion Wave (Table D). Correlations between FFR / CFVR measured distal to the stented lesion post PCI with the cumulative intensities of the six coronary waves. No significant correlations were observed between FFR / CFVR and cumulative accelerative wave intensity post PCI. The Spearman correlation coefficient was applied to estimate statistical significance. FFR, Fractional Flow reserve; CFVR, Coronary Flow Velocity Reserve; sFCW, systolic Forward travelling Compression Wave; dBEW, diastolic Backward travelling Expansion Wave (Table E). (DOCX)
