BACKGROUNDThe hybrid procedure for coronary heart disease combines minimally invasive coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) and is an alternative to revascularization treatment. We sought to assess the predictive value of four risk-stratification models for risk assessment of major adverse cardiac and cerebrovascular events (MACCE) in patients with multivessel disease undergoing hybrid coronary revascularization.

METHODSThe data of 120 patients were retrospectively collected and the SYNTAX score, EuroSCORE, SinoSCORE and the Global Risk Classification (GRC) calculated for each patient. The outcomes of interest were 2.7-year incidences of MACCE, including death, myocardial infarction, stroke, and any-vessel revascularization.

RESULTSDuring a mean of 2.7-year follow-up, actuarial survival was 99.17%, and no myocardial infarctions occurred. The discriminatory power (area under curve (AUC)) of the SYNTAX score, EuroSCORE, SinoSCORE and GRC for 2.7-year MACCE was 0.60 (95% confidence interval 0.42 - 0.77), 0.65 (0.47 - 0.82), 0.57 (0.39 - 0.75) and 0.65 (0.46 - 0.83), respectively. The calibration characteristics of the SYNTAX score, EuroSCORE, SinoSCORE and GRC were 3.92 (P = 0.86), 5.39 (P = 0.37), 13.81 (P = 0.32) and 0.02 (P = 0.89), respectively.

CONCLUSIONSIn patients with multivessel disease undergoing a hybrid procedure, the SYNTAX score, EuroSCORE, SinoSCORE and GRC were inaccurate in predicting MACCE. Modifying risk-stratification models to improve the predictive value for a hybrid procedure is needed.

PURPOSE: Coronary artery bypass grafting (CABG) is the optimal treatment option for left main coronary artery disease (LMCAD). However, LMCAD remains a constant topic of discussion between cardiac surgeons and interventional cardiologists. The aim of this study was to assess the efficacy of LMCAD treatments by comparing the mid-term outcomes of CABG and percutaneous coronary intervention (PCI) using bare metal stents or drug-eluting stents (DESs). MATERIALS AND METHODS: The study population was comprised of 199 consecutive patients admitted with unprotected LMCAD. All of the patients were assigned to PCI (88 patients) or CABG (111 patients). The primary clinical end point indicated death, stroke of acute coronary syndrome (ACS). RESULTS: Patients assigned to PCI were at higher operative risk than patients scheduled for CABG (6.49+/-4.09 vs. 4.81+/-2.67, p=0.0032). Comparison of the group that received DESs with the CABG group did not reveal any differences in major adverse cardio-cerebral events (MACCE) occurrence (21% vs. 16%, p=NS). Patients in the CABG and PCI groups died with similar frequency (11% vs. 16%, p=NS). The mortality rate in the CABG group was higher than among those treated with DES (11% vs. 3%, p=0.049). The rate of ACS was higher in the PCI group than in the CABG group (13% vs. 4%, p=0.016). CONCLUSION: Despite the fact that patients treated with PCI were at higher operative risk, PCI with DES was shown to be comparable to CABG in terms of mortality, stroke and ACS. However, the frequency of repeat revascularizations remains a constant concern with PCI.

BACKGROUND: There are few reports of peri-operative application of intra-aortic balloon pumping (IABP) in patients with coronary artery disease (CAD) and different grades of left ventricular dysfunction. This study aimed to analyze the early outcomes of peri-operative application of IABP in coronary artery bypass grafting (CABG) among patients with CAD and left ventricular dysfunction, and to provide a clinical basis for the peri-operative use of IABP. METHODS: A retrospective analysis of 612 patients who received CABG in the General Hospital of People's Liberation Army between May 1995 and June 2014. Patients were assigned to an IABP or non-IABP group according to their treatments. Logistic regression analysis was performed to investigate the influence of peri-operative IABP implantation on in-hospital mortality. Further subgroup analysis was performed on patients with severe (ejection fraction [EF] ≤ 35%) and mild (EF = 36%-50%) left ventricular dysfunction. RESULTS: Out of 612 included subjects, 78 belonged to the IABP group (12.7%) and 534 to the non-IABP group. Pre-operative left ventricular EF (LVEF) and EuroSCOREII predicted mortality was higher in the IABP group compared with the non-IABP group (P < 0.001 in both cases), yet the two did not differ significantly in terms of post-operative in-hospital mortality (P = 0.833). Regression analysis showed that IABP implantation, recent myocardial infarction, critical status, non-elective operation, and post-operative ventricular fibrillation were risk factors affecting in-hospital mortality (P < 0.01 in all cases). Peri-operative IABP implantation was a protective factor against in-hospital mortality (P = 0.0010). In both the severe and mild left ventricular dysfunction subgroups, peri-operative IABP implantation also exerted a protective role against mortality (P = 0.0303 and P = 0.0101, respectively). CONCLUSIONS Peri-operative IABP implantation could reduce the in-hospital mortality and improve the surgical outcomes of patients with CAD with both severe and mild left ventricular dysfunction.

There is no consensus as to which acute myocardial infarction subtype poses a greater risk after coronary artery bypass grafting (CABG). We compared the early and the long term results of off-pump coronary artery bypass grafting (OPCAB) between patients with STEMI (group I, n = 83), and NSTEMI (group II, n = 237). Group I had higher EuroSCORE, prevalence of emergency surgery, preoperative intra-aortic balloon pump use, preoperative emergency percutaneous transluminal coronary angioplasty, and preoperative thrombolytic use than group II. There were no significant differences in 30-day mortality and major adverse cardiac and cerebrovascular event (MACCE) between groups. Overall 8-yr survival was 93% and 87% in groups I and II, respectively. Freedom from MACCE after 8 yr was 92% and 93% in groups I and II, respectively. After propensity score matching analysis, there were no significant differences in preoperative parameters, postoperative in-hospital outcomes, and long-term clinical outcomes. Surgical results of OPCAB in patients with acute myocardial infarction show good results in terms of long-term survival and freedom from MACCE, with no significant differences in clinical outcomes between STEMI and NSTEMI groups.

BACKGROUNDTransmyocardial laser revascularization (TMLR) has been used in the treatment of patients with end-stage coronary artery disease (CAD) since 1990. The aim of this study was to evaluate the long-term effectiveness of TMLR in patients with diffuse CAD.

METHODSNinety-four consecutive patients underwent TMLR in one center from July 1997 to December 2000. The follow-up data of these patients were obtained through face-to-face, mail questionnaires, or telephone interviews in July 2004 and December 2004. Four cases failed to respond. Mean follow-up time was (5.5 +/- 1.0) years.

RESULTSMean Canadian Cardiovascular Society (CCS) angina scores of TMLR patients were 3.1 +/- 0.8 at baseline, 1.7 +/- 0.9 at 1 year (P < 0.05), 1.7 +/- 0.9 at 3 years (P < 0.05), and 1.9 +/- 0.9 at 5 years (P < 0.05). At an average of 5 years, 69% of the patients had > or = 1 angina class reduction, mean NYHA class level (1.9 +/- 0.9) ameliorated compared to the baseline (2.5 +/- 0.7, P < 0.001), the rate of re-hospitalization was 2.7 times/person. Kaplan-Meier survival rate was 87% at 1 year, 69% at 3 years and 64% at 5 years. The causes of death were attributed more to heart failure (58.9%) and myocardial infraction (14.7%) after TMLR. The patients with no angina relief, or who died after TMLR, had a higher percentage of preoperative unstable anginas or prior myocardial infraction compared to the survivors. The assorted shapes of myocardial laser channels were detected in some patients by the color Doppler velocity technique.

CONCLUSIONSTMLR provided a long-term improvement in the quality of life, including CCS angina class or NYHA heart functional class for about 70% of Chinese patients with severely disabling angina pectoris. The various myocardial laser channels would always be visible after TMLR. 5-years after TMLR as a sole therapy, the survival rate of the patients was 64%.
