Abstract
OBJECTIVE This study aimed to compare the results of off-pump and on-pump coronary artery bypass grafting in older adults and to examine early and late outcomes. METHODS This study included 226 patients aged ≥ 75 years who underwent isolated coronary artery bypass grafting. Of these, 141 and 85 patients were included in the off-pump and on-pump groups, respectively. Propensity scores were calculated for each case, matched, and compared between the two groups (68 cases in each group), along with mid-term outcomes of survival and major adverse cardiac events. RESULTS Operative time, red blood cell transfusion volume, and postoperative hospital stay duration were significantly higher in the on-pump group (267 vs 370 min, P < 0.001; 4.3 vs 17.2 units, P < 0.001; and 20.8 vs 35.8 days, P = 0.012, respectively). Postoperative occurrence of new atrial fibrillation was significantly higher in the on-pump group (4.4% vs 27.9%, P < 0.001), and Kaplan-Meier survival analysis showed a significantly worse prognosis in the on-pump group than in the off-pump group (3-year survival rate 90.7% vs 71.5%, log rank P = 0.007). However, there was no statistically significant difference in cardiovascular-related deaths (log rank P = 0.07). CONCLUSIONS On-pump coronary artery bypass grafting in an older adult population resulted in increased transfusion volume and postoperative occurrence of atrial fibrillation. The mid-term postoperative outcomes were also poorer with on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting reduced future all-cause deaths in older adults.

Induced blood oxidation in myocardial revascularization. КЛИНИЧЕСКАЯ ПРАКТИКА 2022. [DOI: 10.17816/clinpract107847] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/08/2022] Open
Abstract
Background: The use of artificial circulation in surgical myocardial revascularization is one of the key pathogenetic factors in the development of the oxidative stress and systemic inflammatory response in the postoperative period. Aims: the purpose of the study was to describe the dynamics of the induced blood oxidation parameters during coronary artery bypass surgery in the conditions of artificial circulation and on the working heart. Methods: The study included 64 patients who underwent coronary bypass surgery, with 31 (48.4%) on-pump patients and 33 (51.6%) off-pump patients. The oxidative stress simulations were conducted under the in vitro conditions. The blood oxidation-induced values were studied using a biological oxygen monitor. Results: In patients with coronary heart disease, regardless of the choice of the revascularization method (on-pump / off-pump), we observed statistically significantly (p 0.05) higher initial and maximum blood oxidation rates, the oxidative activity factor, and a shorter initiation period than those in healthy volunteers. No significant differences were found by the inter-group comparison analysis both 10 days and 6 months post-surgery. Conclusion: The indicators of induced blood oxidation do not depend on the method of revascularization during coronary bypass grafting (artificial circulation or a working heart). The changes in the parameters indicating activation of the oxidative and antioxidant blood systems may be transient by their nature and occur in the early postoperative period.

Zhang H, Zhao Z, Yao J, Zhao J, Hou T, Wang M, Xu Y, Wang B, Niu G, Sui Y, Song G, Wu Y. Prior percutaneous coronary intervention and outcomes in patients after coronary artery bypass grafting: a meta-analysis of 308,284 patients. Ther Adv Chronic Dis 2022; 13:20406223221078755. [PMID: 35586304 PMCID: PMC9109498 DOI: 10.1177/20406223221078755] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Accepted: 01/20/2022] [Indexed: 12/02/2022] Open
Abstract
Background: The association between prior percutaneous coronary intervention (PCI) and
prognosis after coronary artery bypass grafting (CABG) remains uncertain. We
aimed to evaluate the aforementioned association in a meta-analysis. Methods: PubMed, Cochrane’s Library, and Embase databases were searched for potential
studies. A random-effects model was used for the meta-analysis.
Meta-regression was performed to evaluate the influence of study
characteristics on the outcomes. Results: Thirty-six follow-up studies with 308,284 patients were included, and 40,892
(13.3%) patients had prior PCI. Pooled results showed that prior PCI was
associated with higher risks of early (in-hospital or within 1 month)
all-cause mortality [odds ratio (OR): 1.26, 95% confidence interval (CI):
1.11–1.44, p = 0.003; I2 = 64%]
and major adverse cardiovascular events (MACEs; OR: 1.36, 95% CI: 1.12–1.66,
p = 0.002, I2 = 79%), but
not with late (follow-up durations from 1 to 13 years) mortality (OR: 1.03,
95% CI: 0.95–1.13, p = 0.44,
I2 = 46%) or MACEs (OR: 1.03, 95% CI: 0.97–1.09,
p = 0.38, I2 = 0%).
Meta-regression showed that the study characteristics of patient number,
age, sex, diabetic status, and proportion of patients with prior PCI did not
affect the outcomes. Sensitivity analyses limited to multivariate studies
excluding patients with acute PCI failure showed similar results (early
mortality, OR: 1.25, p = 0.003; early MACE, OR: 1.50,
p = 0.001; late mortality, OR: 1.03,
p = 0.70). Conclusion: The current evidence, mostly from retrospective observational studies,
suggests that prior PCI is related to poor early clinical outcomes, but not
to late clinical outcomes, after CABG.
