Eligibility
Inclusion criteria
Inclusion criteria: 1. Adults aged 18 to 80 years; 2. Non-urgent or non-emergent off-pump coronary artery bypass grafting surgery (CABG) surgery and valvular surgery; 3. Left ventricular EF > 40%; 4. Patients undergoing heart surgery for the first time; 5. No history of adult congenital heart disease or valvular disease; 6. Good compliance and ability to complete follow-up; 7. Epicardial leads were implanted during hospitalization.
Exclusion criteria
Exclusion criteria: 1. History of prior cardiac surgery; 2. Heart surgery was accompanied by surgery of other organ system; 3. Liver and kidney function abnormality (results exceed the upper limit of normal value by 3 times); or with CABG or valvular surgery contraindications; 4. Patients suffering from other diseases who require radiotherapy, or chemotherapy, and/or long-term hormone treatment; 5. Patients who declined to consent to the surgical procedure; 6. Patient who were unable to have epicardial leads implanted during hospitalization; 7. Patients in need of other critical cares that the data collection became inconvenient or not applicable such as those requiring pressor agents or antiarrhythmic drugs.
