It is recommended to continue chronic therapy for pulmonary arterial hypertension（PAH） in the perioperative phase of non-cardiac surgery（NCS）.(Evidence: Level C，Recommendation: Class Ⅰ)

It is recommended that haemodynamic monitoring of patients with severe pulmonary arterial hypertension（PAH） continues for at least 24 h in the postoperative period.(Evidence: Level C，Recommendation: Class Ⅰ)

In the case of progression of right heart failure（HF） in the postoperative period in patients with pulmonary arterial hypertension（PAH）, it is recommended that the diuretic dose be optimized and, if necessary, i.v. prostacyclin analogues be initiated under the guidance of a physician experienced in the management of pulmonary arterial hypertension（PAH）.(Evidence: Level C，Recommendation: Class Ⅰ)

Inodilator drugs (dobutamine,milrinone,levosimendan),which increase cardiac output and lower pulmonary vascular resistance,should be considered perioperatively according to the haemodynamic status of the patient.(Evidence: Level C，Recommendation: Class IIa)

In patients with chronic hypertension undergoing elective NCS, it is recommended to avoid large peri-operative fluctuations in blood pressure, particularly hypotension, during theperi-operative period.(Evidence: Level A ，Recommendation: Class I)

It is recommended to perform pre-operative screening for hypertension-mediated organ damage and CV risk factors in newly diagnosed hypertensive patients who are scheduled for elective high-risk NCS.(Evidence: Level C，Recommendation: Class Ⅰ)

It is not recommended to defer NCS in patients with stage 1 or 2 hypertension.(Evidence: Level C，Recommendation: Class III)

In patients with poor functional capacity or significant risk factors or symptoms (such as moderate-to-severe angina pectoris,decompensated heart failure（HF）, valvular disease,and significant arrhythmia), referral for cardiac work-up and optimization is recommended prior to elective surgery for peripheral artery disease（PAD） or abdominal aortic aneurysm（AAA）.(Evidence: Level C，Recommendation: Class Ⅰ)

Routine referral for cardiac work-up, coronary angiography,or cardiopulmonary exercise testing（CPET） prior to elective surgery for peripheral artery disease（PAD） or abdominal aortic aneurysm(AAA) is not recommended.(Evidence: Level C，Recommendation: Class III)

Preoperative carotid artery and cerebral imaging is recommended in patients with a history of transient ischaemic attack(TIA) or stroke in the previous 6 months and who have not undergone ipsilateral revascularization.(Evidence: Level C，Recommendation: Class Ⅰ)
