TTE may be considered in patients with poor functional capacity, abnormal ECG, high NT-proBNP/BNP, or ≥1 clinical risk factor before intermediate-risk NCS.(Evidence: Level B ，Recommendation:Class IIb)

To avoid delaying surgery, a FOCUS exam performed by trained specialists may be considered as an alternative to TTE for pre-operative triage.(Evidence: Level B ，Recommendation:Class IIb)

Routine pre-operative evaluation of LV function is not recommended.(Evidence: Level C，Recommendation: Class Ⅲ)

Stress imaging is recommended before high-risk elective NCS in patients with poor functional capacityc and high likelihood of CAD or high clinical risk.(Evidence: Level B，Recommendation:Class Ⅰ)

Stress imaging should be considered before high-risk NCS in asymptomatic patients with poor functional capacity,d and previous PCI or CABG. （Evidence: Level C，Recommendation:Class II a）

Stress imaging may be considered before intermediate-risk NCS when ischaemia is of concern in patients with clinical risk factors and poor functional capacity.（Evidence: Level B，Recommendation:Class II b）

Stress imaging is not recommended routinely before NCS.(Evidence: Level C，Recommendation: ClassⅢ )

It is recommended to use the same indications for ICA and revascularization pre-operatively as in the non-surgical setting.(Evidence: Level C，Recommendation:Class Ⅰ)

CCTA should be considered to rule out CAD in patients with suspected CCS or biomarker-negative NSTE-ACS in case of low-to-intermediate clinical likelihood of CAD, or in patients unsuitable for non-invasive functional testing undergoing non-urgent, intermediate-, and high-risk NCS（Evidence: Level C，Recommendation:Class IIa）

Pre-operative ICA may be considered in stable CCS patients undergoing elective surgical CEA.（Evidence: Level B，Recommendation:Class IIb）
