简要总结

This trial will address essential questions of the efficacy and safety of MICS-CABG in addition to the quality of life and patency rate of the grafts. The study will also address the impact of patients' preferences on external validity and internal validity. In this study, patients with a preference will be allocated to treatment strategies accordingly, whereas only those patients without a distinct preference will be randomized. The randomized trial is a 248-patient controlled, randomized, investigator-blinded trial. It is designed to compare whether treatment with MICS-CABG is beneficial in comparison to CABG. This study is aimed to establish the superiority hypothesis for the physical component summary (PCS) accompanied by the noninferiority hypothesis for overall graft patency. Patients with no treatment preference will be randomized in a 1:1 fashion to one of the two treatment arms. The primary efficacy endpoints are the PCS score at 30 days (1 month) after surgery and the overall patency rate of the grafts within 14 days ( before discharge) after surgery. Secondary outcome measures include the PCS score and patency rate at different time points. Safety endpoints include major adverse cardiac and cerebrovascular events, complications, bleeding, wound infection, death, etc.

详细描述

Objective and Hypothesis: The aim of this study is to investigate and compare the mid-term safety and efficacy end-points (SF-36 PCS at 30 days after surgery, etc.) in patients with complex coronary artery lesions (an indication of OPCAGB) who received MICS-CABG and those who received thoracotomy OPCABG. The investigators hypothesize that patients in MICS-CABG group have superior 1-month PCS score assessed by SF-36 post-surgery and noninferior postprocedural angiographic graft patency rate prior to discharge.

Intervention Methods:

  1. MICS-CABG (experimental group): Off-pump multi-vessel coronary artery bypass grafting via left thoracotomy under minimally invasive conditions.

  2. Surgery preparation:

General anesthesia, double lumen tracheal intubation. In the supine position, tilt 15° to the right. An automatic defibrillation electrode is attached to the right front and left rear chest wall, and the external defibrillator is connected. A small incision of 8-10 cm into the left anterior lateral 5th intercostal space was performed into the chest. 2. Internal mammary artery acquisition:

结局指标

主要结局

SF-36 PCS score (Physical component summary of medical outcomes study-short form 36-item scores) at 30 days (1month) after surgery

时间窗: 30 days (1 month) after surgery

The SF-36 is a concise health test that features Physical Functioning (PF), Roe-Physical (RP), Bodily Pain, General Health (GH), Vitality (VT), Social Functioning (SF), Roe-Emotional (Emotional) and Mental Health (MH) functioning and comprehensively summarizes the quality of life of the respondents across 8 aspects. The PCS and mental component summary (MCS) can be calculated from the eight abovementioned indicators with different weights. The PCS and the MCS each range from 0 to 50, with a lower score indicating worse quality of life (QoL) and a higher score indicating better QoL.

Overall patency rate of the grafts

时间窗: within 14 days after surgery (before discharge)

the patency rates of the LIMA, RIMA, saphenous vein graft (SVG) and radial artery (RA) will be evaluated by the Fitzgibbon A+B grade
