Brief Summary:
This study is a multicenter randomized controlled trial comparing an intensive intraoperative blood pressure management strategy versus conventional practice for preventing cardiovascular events in high-risk patients undergoing major abdominal surgery.

Condition or disease Intervention/treatment Phase
Cardiovascular Complication Other: Intensive intraoperative blood pressure management Other: Conventional intraoperative blood pressure management Not Applicable

Detailed Description:
Intraoperative hypotension has been associated with cardiovascular events after non-cardiac surgery. However, whether avoiding intraoperative hypotension can reduce the incidence of postoperative cardiovascular events remains unclear. The objective of this study is to assess the effects of an intensive intraoperative blood pressure management strategy (to maintain intraoperative MAP ≥ 80mmHg) with that of conventional practice (to maintain intraoperative MAP ≥ 65mmHg) on the incidence of cardiovascular events after major abdominal surgery.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of participants with major adverse cardiac events [ Time Frame: 30-day after surgery ]
    A composite of myocardial injury/infarction, new-onset clinically important arrhythmia, heart failure, stroke, cardiac arrest, and all-cause death after surgery


Secondary Outcome Measures :
  1. Number of participants with non-cardiovascular complications [ Time Frame: 30-day after surgery ]
    Postoperative acute kidney injury, infection, pulmonary complications, delirium, gastrointestinal complications (GI infarction, bleeding, perforation, obstruction), venous thromboembolism, anastomotic fistula, bleed requiring transfusion

  2. Days alive and at home [ Time Frame: 30-day after surgery ]
  3. Number of participants who died or developed disability [ Time Frame: 180-day after surgery ]
    Disability is assessed based on 12-item WHO Disability Assessment Schedule (WHODAS 2.0)


Other Outcome Measures:
  1. For patients receiving radical cancer resection: overall survival [ Time Frame: 3-year after surgery ]
  2. For patients receiving radical cancer resection: disease-free survival [ Time Frame: 3-year after surgery ]
