…depend heavily on the amount of viable myocardium supplied by the affected artery. Large areas of jeopardized myocardium, severe baseline stenosis, multivessel coronary artery disease…

…baseline stenosis, multivessel coronary artery disease, or diffuse disease. No reflow represents impaired antegrade myocardial perfusion in the absence of a flow limiting epicardial stenosis…

…sectional and longitudinal information about the artery. The clinical value of these techniques rests on their ability to characterize the anatomy responsible for a stenosis…

…Occlusion of the left main coronary artery (LMCA) abruptly interrupts blood flow to both the left anterior descending (LAD) and left circumflex (LCx) coronary artery…

…stenosis severity is a poor surrogate for the hemodynamic significance of a coronary lesion, with anatomic and functional assessment discordant in a substantial minority of…

…with symptoms. Current guidance supports revascularisation for significant left main stenosis irrespective of symptomatic status or the documented ischaemic burden. In chronic coronary syndrome, revascularisation…

…direct measurement of coronary blood flow, providing absolute quantification. The resting myocardium rarely reveals evidence of significant coronary artery stenosis unless the stenosis is severely…

…greater the stenosis, the lower the level of myocardial workload required to elicit ischemia and symptoms. Angina pectoris: the hallmark of coronary artery disease Angina…
