What researchers measure

Primary outcomes

  1. The event rate of composite event of all-cause death, stent thrombosis, myocardial infarction, and stroke

    A composite endpoint is an endpoint that is a combination of multiple clinical endpoints. An event that is considered to have occurred if any one of several different events is observed.

    Time frame: 30 days

Secondary outcomes

  1. The event rate of all cause death

    Time frame: 30 days

  2. The event rate of cardiac death

    Time frame: 30 days

  3. The event rate of myocardial infarction

    Time frame: 30 days

  4. The event rate of stroke

    Time frame: 30 days

  5. The event rate of stent thrombosis

    Time frame: 30 days

  6. The event rate of repeat revascularization

    Time frame: 30 days

  7. The event rate of life threatening bleeding

    Time frame: 30 days

  8. The event rate of major bleeding

    Time frame: 30 days

  9. Quality of life score assessed by the EQ-5D-5L

    The EQ-5D-5L essentially consists of 2 pages: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. Higher score of EQ-5D and EQ VAS means the low quality of life. EQ-5D: the minimum and maximum values are 5 and 25 respectively. EQ VAS: the minimum and maximum values are 0 and 100 respectively.

    Time frame: 30 days

  10. Quality of life score assessed by Health-related Quality of Life Instrument with 8 Items (HINT-8)

    HINT-8 was developed based on 4 health dimensions: physical, mental, social, and positive health dimensions. It consists of climbing stairs, endurance to pain, vitality, working, depression, memory, sleep, and happiness. Higher score of HINT-8 means the high quality of life. The minimum and maximum values are 0 and 100 respectively if convert to a percentage.

    Time frame: 30 days

  11. Cost-effective analysis

    Cost-effective analysis based on average treatment costs for two perioperative antiplatelet therapy_Aspirin only vs. No antiplatelet therapy_in patients with drug-eluting stent undergoing non-cardiac surgery.

    Time frame: 30 days
