Brief Summary:
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.
Detailed Description:
Fractional Flow Reserve (FFR) is the gold standard for determining the functional ischemia of coronary arteries with intermediate lesions. Both intracoronary nitroglycerine (NTG) administration and saline administration induce an acute drop in trans-lesional coronary pressure. Both pressure ratios correlate well with FFR values and can reliably predict positive results in FFR assessments. The aims of this study were
1. To evaluate the numerical difference between NTG-Pd/Pa and saline-Pd/Pa.
2. To test the repeatability of saline-Pd/Pa.
3. To compare the diagnostic performance of NTG-Pd/Pa and saline-Pd/Pa in predicting the binary result of FFR assessment.
Participants will be enrolled prospectively from National Taiwan University Hospital Hsinchu Hospital, Miaoli General Hospital, and Taichung Veterans General Hospital. The coronary artery with intermediate stenosis will undergo NTG-Pd/Pa, saline-Pd/Pa, and FFR assessments sequentially. Saline-Pd/Pa will be tested repeatedly during the assessment.
