QCA and QFR analyses were performed on major coronary arteries. CAD progression was defined in 2 ways: (1) QCA diameter stenosis (DS) increase \u2265\u200910% or baseline &lt;\u200950% and follow\u2011up \u2265\u200950%; (2) QFR decrease \u2265\u20090.05 or baseline QFR &gt;\u20090.80 and follow\u2010up\u2009\u2264\u20090.80.

Among vessel subsegments, CAD progression by QCA was greatest in the LAD proximal and mid segments (60.99% and 58.46%, respectively), and lowest in distal LCX and distal RCA (37.63%, 39.04%, respectively). CAD progression by QFR was significantly greater in SEV when compared to BEV (1\u2010year: 39.4% vs. 21.9%; 2\u2010year: 47.4% vs. 39.3%, log rank\n                      <jats:italic>p\u2009<\/jats:italic>\n                      =\u20090.038).
