Comparison of coronary artery bypass grafting and percutaneous coronary intervention in patients with heart failure with reduced ejection fraction and multivessel coronary artery disease.

ABSTRACT: To compare coronary artery bypass grafting (CABG) with percutaneous coronary interventions (PCI) in patients with heart failure with reduced ejection fraction (HFrEF) and multivessel coronary artery disease.1213 patients were selected from institutional databases, 761 and 452 in CABG and PCI group respectively. Only the subjects with left ventricle ejection fraction ? 35% and multivessel coronary artery disease were included to the study. The primary outcome measure was long-term all-cause death, the secondary outcomes were recurrent myocardial infarction, urgent repeat revascularization and stroke. Propensity Score-Based Adjusted Survival Curves were used for revascularization methods comparison.Survival rates were similar in both groups (HR, 0.91; 95% CI, 0.65-1.28; p=0.59). Recurrent myocardial infarction was observed significantly less often in the CABG group (HR, 0.44; 95% CI, 0.26-0.74; p=0.002). Repeat urgent revascularization was less frequent in the CABG group (HR, 0.50; 95% CI, 0.30-0.84; p=0.008). The rate of stroke did not differ between the groups (HR, 1.17; 95% CI, 0.62-2.22; p=0.62).In patients with HFrEF and multivessel CAD revascularization both with CABG and PCI resulted in similar survival rates. PCI is associated with increased risk of recurrent MI and urgent repeat revascularization, whereas the risk of stroke is similar in both methods.

Project description:ImportanceData are lacking on the outcomes of patients with severely reduced left ventricular ejection fraction (LVEF) who undergo revascularization by percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG).ObjectiveTo compare the long-term outcomes in patients undergoing revascularization by PCI or CABG.Design, setting, and participantsThis retrospective cohort study performed in Ontario, Canada, from October 1, 2008, and December 31, 2016, included data from Ontario residents between 40 and 84 years of age with LVEFs less than 35% and left anterior descending (LAD), left main, or multivessel coronary artery disease (with or without LAD involvement) who underwent PCI or CABG. Exclusion criteria were concomitant procedures, previous CABG, metastatic cancer, dialysis, CABG and PCI on the same day, and emergency revascularization within 24 hours of a myocardial infarction (MI). Data analysis was performed from June 2, 2018, to December 28, 2018.ExposuresRevascularization by PCI or CABG.Main outcomes and measuresThe primary outcome was all-cause mortality. Secondary outcomes were death from cardiovascular disease, major adverse cardiovascular events (MACE; defined as stroke, subsequent revascularization, and hospitalization for MI or heart failure), and each of the individual MACE.ResultsA total of 12 113 patients (mean [SD] age, 64.8 (11.0) years for the PCI group and 65.6 [9.7] years for the CABG group; 5084 (72.5%) male for the PCI group and 4229 (82.9%) male for the PCI group) were propensity score matched on 30 baseline characteristics: 2397 patients undergoing PCI and 2397 patients undergoing CABG. The median follow-up was 5.2 years (interquartile range, 5.0-5.3). Patients who received PCI had significantly higher rates of mortality (hazard ratio [HR], 1.6; 95% CI, 1.3-1.7), death from cardiovascular disease (HR 1.4, 95% CI, 1.1-1.6), MACE (HR, 2.0; 95% CI, 1.9-2.2), subsequent revascularization (HR, 3.7; 95% CI, 3.2-4.3), and hospitalization for MI (HR, 3.2; 95% CI, 2.6-3.8) and heart failure (HR, 1.5; 95% CI, 1.3-1.6) compared with matched patients who underwent CABG.Conclusions and relevanceIn this study, higher rates of mortality and MACE were seen in patients who received PCI compared with those who underwent CABG. The findings may provide insight to physicians who are involved in decision-making for these patients.

Project description:Background and Aims: Patients with heart failure with reduced ejection fraction (HFrEF) are among the most challenging patients undergoing coronary artery bypass grafting surgery (CABG). Several surgical risk scores are commonly used to predict the risk in patients undergoing CABG. However, these risk scores do not specifically target HFrEF patients. We aim to develop and validate a new nomogram score to predict the risk of in-hospital mortality among HFrEF patients after CABG. Methods: The study retrospectively enrolled 489 patients who had HFrEF and underwent CABG. The outcome was postoperative in-hospital death. About 70% (n = 342) of the patients were randomly constituted a training cohort and the rest (n = 147) made a validation cohort. A multivariable logistic regression model was derived from the training cohort and presented as a nomogram to predict postoperative mortality in patients with HFrEF. The model performance was assessed in terms of discrimination and calibration. Besides, we compared the model with EuroSCORE-2 in terms of discrimination and calibration. Results: Postoperative death occurred in 26 (7.6%) out of 342 patients in the training cohort, and in 10 (6.8%) out of 147 patients in the validation cohort. Eight preoperative factors were associated with postoperative death, including age, critical state, recent myocardial infarction, stroke, left ventricular ejection fraction (LVEF) ≤35%, LV dilatation, increased serum creatinine, and combined surgery. The nomogram achieved good discrimination with C-indexes of 0.889 (95%CI, 0.839-0.938) and 0.899 (95%CI, 0.835-0.963) in predicting the risk of mortality after CABG in the training and validation cohorts, respectively, and showed well-fitted calibration curves in the patients whose predicted mortality probabilities were below 40%. Compared with EuroSCORE-2, the nomogram had significantly higher C-indexes in the training cohort (0.889 vs. 0.762, p = 0.005) as well as the validation cohort (0.899 vs. 0.816, p = 0.039). Besides, the nomogram had better calibration and reclassification than EuroSCORE-2 both in the training and validation cohort. The EuroSCORE-2 underestimated postoperative mortality risk, especially in high-risk patients. Conclusions: The nomogram provides an optimal preoperative estimation of mortality risk after CABG in patients with HFrEF and has the potential to facilitate identifying HFrEF patients at high risk of in-hospital mortality.

Project description:BackgroundThe concept of hybrid coronary revascularization (HCR) combines the left internal mammary artery (LIMA)-left anterior descending (LAD) graft and percutaneous coronary intervention (PCI) to non-LAD vessels. Multiple comparative studies have evaluated the safety and feasibility of HCR and coronary artery bypass grafting (CABG) for multivessel coronary artery disease (MCAD). However, the sample size of each study was small, and evidences based on single-institutional experience. The purpose of this meta-analysis was to compare the short-term outcomes of HCR with those of CABG for MCAD.MethodPubMed, EMBASE and Cochrane Library databases, as well as conference proceedings, were searched for eligible studies published up to March 2014. We calculated summary odds ratios (OR) for primary endpoints (death, stroke; myocardial infarction (MI); target vessel revascularization (TVR); major adverse cardiac or cerebrovascular events (MACCEs)) and secondary endpoints (atrial fibrillation (AF); renal failure; length of stay in the intensive care unit (LoS in ICU); length of stay in hospital (LoS in hospital); red blood cell (RBC) transfusion). Data from 6176 participants were derived from ten cohort studies.ResultsHCR was non-inferior to CABG in terms of MACCEs during hospitalization (odds ratio (OR), 0.68, 95% confidence interval (CI), 0.34-1.33)and at one-year follow-up(0.32, 0.05-1.89) , and no significant difference was found between HCR and CABG groups in in-hospital and one-year follow-up outcomes of death, MI, stroke, the prevalence of AF and renal failure, whereas HCR was associated with a lower requirement of RBC transfusion and shorter LoS in ICU and LoS in hospital than CABG (weighted mean difference (WMD) -1.25, 95% CI, -1.62 to -0.88; -17.47, -31.01 to -3.93; -1.77, -3.07 to -0.46; respectively).ConclusionOur meta-analysis indicates that HCR is feasible, safe and effective for the treatment of MCAD, with similar in-hospital and one-year follow-up outcome, significantly lower requirement of RBC transfusion, and faster recovery compared with CABG.
