Comparative study of minimally invasive versus median sternotomy off-pump coronary artery bypass grafting based on propensity score matching
摘要
Abstract
Objective To compare perioperative outcomes and prognosis between minimally invasive coronary artery bypass grafting(MICABG)and median sternotomy off-pump coronary artery bypass grafting(OPCABG)through a propensity score-matched observational cohort study.Methods Clinical data of CABG patients in our hospital were retrospectively collected.After applying inclusion and exclusion criteria,85 MICABG and 226 OPCABG group patients were enrolled.A 1:1 propensity score matching(PSM)was performed to balance baseline characteristics.Perioperative outcomes and major adverse cardiovascular and cerebrovascular events(MACCE)were compared,with subgroup analysis and survival analysis conducted to evaluate long-term prognosis.Results After matching,the MICABG group demonstrated significantly shorter operative times,reduced intraoperative blood loss,fewer drainage tubes and fewer grafted vessels compared to the OPCABG group(P<0.001).However,no significant differences were observed in the incidence of MACCE,all-cause mortality,non-fatal stroke,non-fatal heart failure,non-fatal myocardial infarction,wound complications,repeat revascularization,cardiac-related readmissions,in-hospital MACCE or in-hospital death between the two groups(all P>0.05).Conclusion MICABG is associated with reduced surgical trauma,faster recovery,and comparable long-term outcomes to OPCABG,suggesting its viability as a less invasive alternative for selected patients.There were no significant differences in prognosis between MICABG and OPCABG patients.关键词
