NTG-Pd/Pa measurement: The coronary artery with intermediate stenosis will sequentially undergo NTG-Pd/Pa, saline-Pd/Pa, and FFR assessments. Intracoronary NTG dosage will follow the protocol based on blood pressure.
Saline-Pd/Pa measurement: The coronary artery with intermediate stenosis will sequentially undergo NTG-Pd/Pa, saline-Pd/Pa, and FFR assessments. Ten millilitres of intracoronary saline will be given over five seconds.
The goal of this observational study is to compare the value of NTG-Pd/Pa and saline-Pd/Pa in participants with intermediate stenosis of the coronary artery. The main questions it aims to answer are:
The numerical difference between NTG-Pd/Pa and saline-Pd/Pa To compare the diagnostic performance of NTG-Pd/Pa and saline-Pd/Pa in predicting the binary result of FFR assessment?
Participants will undergo NTG-Pd/Pa, Saline-Pd/Pa, and FFR successively in the target vessel.
