E-6 | Diagnostic Yield of Invasive Coronary Function Testing Compared With Coronary Angiography Alone in Women With Stable Ischemic Heart Disease

Objective: The aim of this study was to compare the diagnostic yield invasive coronary function testing (CFT) and angiography (CA) alone in women who presented with stable ischemic heart disease (SIHD). SIHD is a leading cause morbidity mortality women, are more likely than men suffer from ischemia no obstructive artery (INOCA). Endotypes INOCA such as vasospasm microvascular dysfunction not identified by routine angiography. As result, many undergo cardiac catheterization for suspected given specific diagnosis or targeted therapeutic plan. CFT comparison CA has been well-established. We conducted retrospective symptoms SIHD. primary outcome post-procedure after CA. Secondary outcomes included post procedure change medications complications. A total 133 were evaluated, including 61 group 72 group. Compared group, receive 41% (n=25) vs. 3% (n=2), vasospastic angina 20% (n=12) 1% (n=1), endothelial (n=5, 8% vs 0%). Other diagnoses elevating resting flow myocardial bridging (n=3), mixed syndromes (n=5). In most commonly received normal arteries (n=15, 21%), non-obstructive (n=54, 75%), other (n=2, 3%). Post-procedure medication changes frequent compared (69% 43%, p<0.001). SIHD, confirmed an underlying vasomotor disorder 85% cases, whereas only reported CAD. able further categorize having angina, resulting higher frequency alone. These findings suggest that should be considered routinely evaluation
