Comparative analysis of in-hospital and long-term results of patients with acute dysfunction of coronary bypass grafts depending on treatment tactics
OBJECTIVE: Comparative analysis of in-hospital and long-term mortality of patients in whom acute dysfunction of coronary bypass grafts was detected in the early postoperative period depending on conservative or surgical tactics.
MATERIAL AND METHODS: The study is a retrospective analysis of data from 8801 patients who underwent elective coronary artery bypass grafting (CABG) between 2011 and 2022 at the Federal Center for Cardiovascular Surgery (Russia, Chelyabinsk). Among them, 196 patients underwent emergency coronary artery bypass grafting due to suspected perioperative myocardial infarction in the early postoperative period. In 119 patients, dysfunction of coronary bypass grafts was detected, in 77 patients no pathological changes were found. The criteria for inclusion in the study were patients with dysfunction of coronary bypass grafts (n=119). The 1st group included patients who underwent conservative therapy (n=33), the 2nd group (n=86) included those who underwent repeated myocardial revascularization. The primary endpoint was hospital mortality, secondary endpoints were long-term mortality and adverse cardiovascular events (myocardial infarction, stroke, repeat myocardial revascularization). Patients were surveyed via telephone.
RESULTS: In-hospital mortality in the group of surgical reintervention was 8.1%, in the group of conservative treatment - 9.1% (p=0.867). According to the results of multivariate analysis, predictors of hospital mortality in patients of both groups were extracorporeal membrane oxygenation (p=0.014), time of artificial circulation (p=0.031), duration of artificial ventilation (p=0.001), number of days in intensive care (p<0.001). When analyzing long-term mortality using the Kaplan-Meier method in group 1 and group 2, no statistically significant differences were found; in the group of conservative therapy - 85±9.6 [66.2-103.7] months versus 108.2±4.8 [98.8-117.6] months in the surgery group (log-rank p=0.06). When analyzing long-term mortality from cardiovascular causes and the occurrence of adverse cardiovascular events, statistically significant differences were determined: in the group of conservative therapy - 92.5±9.3 [74.2-110.7] months versus 117.8±3.3 [111.2-124.3] months in the surgical treatment group (log-rank p=0.007) and 78.1±9.2 [60-96.3] months versus 98.9±3.9 [91.3-106.5] months (log-rank p=0.008), respectively.
CONCLUSION: In-hospital mortality was comparable between groups. Long-term mortality from cardiovascular causes and the number of adverse cardiovascular events were significantly higher in the conservative therapy group. With timely detection of acute dysfunction of coronary bypass grafts, an active surgical approach has an advantage over conservative tactics and can improve the long-term prognosis of patients.
