Abstract:
The evaluation of coronary artery ischemia is of great significance in the diagnosis and treatment of coronary heart disease. In recent years, fractional flow reserve derived from computed tomographic angiography (FFRct) has been used to evaluate the diagnosis of coronary artery specific ischemia, which enriches the clinical management of patients with coronary artery disease. A number of studies have confirmed that FFRct has reliable diagnostic performance compared with invasive fraction flow reserve (FFR). Because of its non-invasive, repeatable measurement and other advantages, the application universality of FFRct is significantly higher than that of invasive examination. At the same time, the application scope of FFRct is also continuously expanding, and it is not limited to its position as a "gatekeeper" for invasive coronary angiography. It has good accuracy in the diagnosis of complex coronary artery disease, and can also be used to guide the choice of surgical strategies such as coronary artery bypass grafting and stent implantation.
