A Comparison of Fractional Flow Reserve by Coronary Angiography Vs. Atherosclerotic Plaque Characteristics by Coronary CTA
In the era of progressive technology, the diagnostic modalities for stable coronary artery disease are various. The original cardiac stress test has been used in the past for many purposes, including diagnosis of obstructive coronary artery disease in a patient with chest pain as well as risk stratification for ischemia. More recently, coronary computed tomographic angiography (CCTA) has emerged as a great tool to diagnose anatomically obstructive coronary lesions. However, for the past few years, obtaining functional and physiologic data such as comparative fractional flow reserve (FFR) has become the gold standard for evidence of ischemia on CCTA similar to invasive angiography.
