Abstract
OBJECTIVE Saphenous vein grafts disease (SVGD) is a common complication after coronary artery bypass graft (CABG) and normally treated by percutaneous coronary intervention (PCI). The most common complication after SVG-PCI is slow or no-reflow. It is known that the no-reflow phenomenon occurs in up to 15% of the SVG-PCI and is associated with high risk of major adverse cardiac events (MACEs) and mortality, therefore, it is important to investigate the factors that could predict the clinical outcome of PCI for risk stratification and guiding interventions. In recent years, the spectral analysis of intravascular ultrasound (IVUS) radiofrequency data (virtual histology-IVUS [VH-IVUS]) has been used to provide quantitative assessment on both plaque compositions and morphologic characteristics. DATA SOURCES The PubMed, Embase, and Central databases were searched for possible relevant studies published from 1997 to 2018 using the following index keywords: "Coronary artery bypass grafting," "Saphenous venous graft disease," "Virtual histology-intravascular ultrasound," "Virtual histology-intravascular ultrasound," and "Percutaneous coronary intervention." STUDY SELECTION The primary references were Chinese and English articles including original studies and literature reviews, were identified and reviewed to summarize the advances in the application of VH-IVUS techniques in situ vascular and venous graft vascular lesions. RESULTS With different plaque components exhibiting a defined spectrum, VH-IVUS can classify atherosclerotic plaque into four types: fibrous tissue (FT), fibro fatty (FF), necrotic core (NC), and dense calcium (DC). The radiofrequency signal is mathematically transformed into a color-coded representation, including lipid, fibrous tissue, calcification, and necrotic core. Several studies have demonstrated the independent relationship between VH-IVUS-defined plaque classification or plaque composition and MACEs, but a significant association between plaque components and no-reflow after PCI in acute coronary syndrome. In recent years, VH-IVUS are applied to assess the plaque composition of SVGD, based on the similarity of pathophysiological mechanisms between coronary artery disease (CAD) and SVGD, further studies with the larger sample size, the long-term follow-up, multicenter clinical trials may be warranted to investigate the relationship between plaque composition of saphenous vein graft (SVG) by VH-IVUS and clinical outcomes in patients with SVGD undergoing PCI. CONCLUSIONS In degenerative SVG lesions, VH-IVUS found that plaque composition was associated with clinical features, future studies need to explore the relationship between VH-IVUS defined atherosclerotic plaque components and clinical outcomes in SVGD patients undergoing PCI, an innovative prediction tool of clinical outcomes can be created.

Abstract
OBJECTIVES Saphenous vein graft (SVG) remains the predominant conduit used in coronary surgery. The internal mammary artery has higher later term patency and confers superior survival. Current debate focuses on the increased use of arterial conduits rather than eradication of venous conduits. METHODS Patient data extracted from the Australian and New Zealand Society of Cardiothoracic Surgeons database from 2001-2013 were linked to the national death registry held by the Australian Institute of Health and Welfare for all-cause mortality with censor date 7 October 2014. The dataset was divided according to use of SVG rather than the arterial conduit. Analyses of SVG ≥ 1 or SVG = 1 were compared to SVG = 0. Additionally, groups of 3, 4 or 5 grafts were subjected to multiple analyses testing the mortality hazard with increasing use of SVG. Propensity score matched analyses were conducted using 24 variables. RESULTS Of 51 113 primary coronary surgery patients, unmatched survival at up to 12.5 years was significantly lower for SVG ≥ 1, n = 33 359, mortality hazard ratio (HR) 1.24 [95% confidence interval (CI) 1.18-1.30], P < 0.001; and for SVG = 1, mortality HR 1.19 (95% CI 1.12-1.26), P < 0.001. Similar results were present for the propensity score matched groups; SVG ≥ 1, n = 14 355 pairs, HR 1.22 (95% CI 1.15-1.30), P < 0.001; and for SVG = 1, n = 12 316 pairs, HR 1.22 (95% CI 1.14-1.30), P < 0.001. All matched analyses within restricted graft groups had increasing HR with increased number of SVG used. CONCLUSIONS Any use of SVGs is independently associated with reduced survival after coronary artery bypass surgery.

Abstract
PURPOSE OF REVIEW To summarize the available evidence on the use of the right internal thoracic artery (RITA) and the radial artery as the second arterial graft in coronary artery bypass surgery. RECENT FINDINGS The current data support the equipoise of the two conduits in terms of clinical and angiographic outcomes. Both RITA and radial artery have better patency than saphenous vein grafts. The use of the RITA carries an increased risk of deep sternal wound infection (DSWI) if the artery is harvested as pedicle. Bilateral internal thoracic artery grafting is more technically demanding than radial artery use and there is a volume-outcome relationship in terms of mortality and incidence of DSWI. The radial artery is preferable over RITA in right-sided or distal circumflex artery targets with high-degree stenosis and in patients at higher risk for DSWI, whereas it is not recommended to graft vessels with moderate stenosis and in cases of insufficient collateralization from the ulnar artery or previous transradial procedures. SUMMARY The patency rate and clinical outcomes of radial artery and RITA are similar. The use of one or the other should be based on a careful evaluation of the patient's coronary anatomy and comorbidities, the conduit availability and the surgeon's and center's experience.

Abstract
Coronary artery bypass grafting (CABG) is known to be an effective method of treatment for multivessel obstructive coronary disease with low rates of reintervention and excellent long-term survival and freedom from angina. Graft patency lies at the heart of its procedural success and durability, which in its turn largely depends on the appropriate choice of the conduit, as well as the target coronary artery (CA). It should be mentioned that patency of one and the same conduit used for bypass grafting of the territory of either the left or right coronary artery (LCA and RCA, respectively) may differ, which is probably determined by differences in physiology, size, territory of runoff, and local flow characteristics between different coronary targets. Previous reports have supported the use of bilateral internal thoracic arteries to revascularize the left coronary circulation. If this becomes standardized practice, the optimal conduit for the right coronary system remains to be established. Proposed in the present article is a variant of bypass grafting of the RCA territory using a composite I-graft formed from the proximal portion of the right internal thoracic artery (ITA) in situ and the great saphenous vein (GSV) harvested by the 'no-touch' technique. This technique is part of a CABG schematic algorithm worked out in our Clinic and called the 'Penza Coronary Technology'.

Abstract
OBJECTIVES Using the British Cardiovascular Intervention Society percutaneous coronary intervention (PCI) database, access site choice and outcomes of patients undergoing PCI with previous coronary artery bypass grafting (CABG) were studied. BACKGROUND Given the influence of access site on outcomes, use of radial access in PCI-CABG warrants further investigation. METHODS Data were analyzed from 58,870 PCI-CABG procedures performed between 2005 and 2014. Multivariate logistic regression was used to identify predictors of access site choice and its association with outcomes. RESULTS The number of PCI-CABG cases and the percentage of total PCI increased significantly during the study period. Femoral artery (FA) utilization fell from 90.8% in 2005 to 57.6% in 2014 (p < 0.001), with no differences in the rate of change of left versus right radial use. In contemporary study years (2012 to 2014), female sex, acute coronary syndrome presentation, chronic total occlusion intervention, and lower operator volume were independently associated with FA access. Length of stay was shortened in the radial cohort. Unadjusted outcomes including an access site complication (1.10% vs. 0.30%; p < 0.001), blood transfusion (0.20% vs. 0.04%; p < 0.001), major bleeding (1.30% vs. 0.40%; p < 0.001), and in-hospital death (1.10% vs. 0.60%; p = 0.001) were more likely to occur with FA access compared with radial access. After adjustment, although arterial complications, transfusion, and major bleeding remained more common with FA use, short- and longer-term mortality and major adverse cardiac event rates were similar. CONCLUSIONS In contemporary practice, FA access remains predominant during PCI-CABG with case complexity associated with it use. FA use was associated with longer length of stay, and higher rates of vascular complications, major bleeding, and transfusion.

Abstract
Objectives To describe changes in mortality among patients undergoing coronary artery bypass grafting (CABG) in New South Wales (NSW) Australia from 2000 to 2013. Methods Patients undergoing CABG were identified from the NSW Admission Patient Data Collection (APDC) registry, linked to the NSW state-wide death registry database. Changes in all-cause mortality over time were observed following stratification of the study cohort into two year groups. Results We identified 54 767 patients undergoing CABG during the study period. The risk profile of patients increased over time with significant increases in age, comorbidities and concomitant valve surgery (all p < 0.0001). During a median follow-up period of 6 years, a total 12 161 (22.2%) of patients had died. Survival curves and adjusted analyses showed a steady fall in mortality rate: those operated on during 2012–2013 had 40 % lower mortality than those operated on during 2000–2001 (HR 0.61; 95% CI 0.53 to 0.69). This was contributed to both by a fall in mortality both in hospital (HR 0.48, 95% CI 0.37 to 0.62) and postdischarge (HR 0.73; 95% CI 0.61 to 0.86). Conclusions We report a consistent reduction in medium-term mortality among a large unselected cohort of NSW patients undergoing CABG between 2000 and 2013. This fall is attributable both to an improvement in outcomes in hospital and in the postdischarge period.

Abstract
Despite the progressive expansion of clinical indications for percutaneous coronary intervention and the increasingly high risk profile of referred patients, coronary artery bypass grafting (CABG) remains the mainstay in multivessel disease, providing good long-term outcomes with low complication rates. Multiple arterial grafting, especially if associated with anaortic techniques, might provide the best longer-term outcomes. A surgical approach individualized to the patients' clinical and anatomic characteristics, and surgeon and team experience, are key to excellent outcomes. Current evidence regarding patient selection, indications, graft selection, and potential strategies to optimize outcomes in patients treated with CABG is summarized.

Abstract
BACKGROUND The RESOLUTE-DIABETES CHINA study was specifically designed to investigate the safety and efficacy of Resolute zotarolimus-eluting stents (ZES; Medtronic, Santa Rosa, CA, USA) in the treatment of diabetic coronary lesions in the Chinese population. METHODS In all, 945 patients with de novo native coronary lesions and type 2 diabetes mellitus were recruited at 32 cardiac centers across the Chinese mainland and were implanted with Resolute ZES. The primary endpoint was target vessel failure (TVF); secondary endpoints were clinical outcomes, namely all-cause death, stroke, bleeding, target lesion revascularization (TLR), target vessel revascularization (TVR), non-TVR, and stent thrombosis (ST). The follow-up period for all endpoints was 12 months after the procedure. RESULTS In all, 933 patients (98.73%) had clinical follow-up at 12 months. The rate of TVF was 11.60%, whereas the rate of occurrence of secondary endpoints was 5.47%, with four patients (0.43%) having subacute or late ST. There were no significant differences in TVF rates comparing patients with different HbA1c levels or receiving different glucose control treatments (all P > 0.05). Patients with multivessel lesions had higher TVF rates (95% confidence intervals) than those with single-vessel lesions (16.76% [12.10%-22.97%) vs 9.72% [7.79%-12.11%], respectively; P = 0.006). There were no significant differences in TVF rates in patients with or without small vessels, bifurcated lesions, or chronic total occlusions (all P > 0.05). [Correction added on 17 January 2019, after first online publication: in the second sentence of Results section, "TLF" was changed to "TVF".]. CONCLUSIONS Resolute ZES may perform well in the Chinese diabetic population, especially in those with poor glucose control, complex lesions, and certain unfavorable clinical features. Further studies are needed to determine why ZES perform well in this population.

BACKGROUND To compare the clinical outcomes between multiple arterial (MA) and single arterial (SA) off-pump coronary artery bypass grafting (OPCAB) when applied to left main coronary disease or three-vessel disease. METHODS A total of 537 patients with left main coronary disease or three-vessel disease underwent MA OPCAB (n=114) or SA OPCAB (n=423) in our center from January 2006 to December 2008. The propensity score matching (PSM) was used to obtain the risk-adjusted outcome. Both the perioperative and long-term results were analyzed. RESULTS The median follow-up time was 117 months (interquartile range, 110 to 128 months). There was no statistical difference in postoperative mortality and the volume of drainage. The intensive care unit (ICU) length of stay (LOS) of the MA group was shorter than that of the SA group {1 [1-2] vs. 2 [1-3], P=0.001). In the long term, the mortality (5.7% vs. 17.5%, P=0.006), cardiac mortality (1.0% vs. 8.8%, P=0.008), fatal myocardial infarction (MI) rate (0.0% vs. 6.1%, P=0.015) and incidence of readmission for heart failure (19.8% vs. 37.7%, P=0.003) were lower in the MA group than in the SA group. The distributions of NYHA class (P<0.001) and CCS class (P<0.001) were better in the MA group than in the SA group. There was no significant difference in other outcomes. These results were consistent with the K-M curves of freedom from the adverse events. CONCLUSIONS MA OPCAB was as safe as SA OPCAB, providing better perioperative recovery and better long-term clinical outcomes in the treatment of left main coronary disease or three-vessel disease.

Abstract
OBJECTIVES To compare the effectiveness and safety of self-expandable, sirolimus-eluting Stentys stents (SES) and second-generation drug-eluting stents (DES-II) for the treatment of the unprotected left main (ULM). BACKGROUND SES may provide a valuable option to treat distal ULM, particularly when significant caliber gaps with side branches are observed. METHODS Patients from the multicenter SPARTA (clinicaltrials.gov: NCT02784405) and FAILS2 registries were included. Propensity-score with matching was performed to account for the lack of randomization. Primary end-point was the rate of major adverse cardiovascular events (MACE, a composite of all cause death, myocardial infarction, target lesion revascularization [TLR], unstable angina and definite stent thrombosis [ST]). Single components of MACE were the secondary end-points. RESULTS Overall, 151 patients treated with SES and 1270 with DES-II were included; no differences in MACE rate at 250 days were observed (9.8% vs. 11.5%, P = 0.54). After propensity score with matching, 129 patients treated with SES and 258 with DES-II, of which about a third of female gender, were compared. After a follow-up of 250 days, MACE rate did not differ between the two groups (9.9% vs. 8.5%, P = 0.66), as well as the rate of ULM TLR (1.6% vs. 3.1%, P = 0.36) and definite ST (0.8% vs. 1.2%, P = 0.78). These results were consistent also when controlling for the treatment with provisional vs. 2-stents strategies for the ULM bifurcation. CONCLUSION SES use for ULM treatment was associated with a similar MACE rate compared to DES-II at an intermediate-term follow-up. SES might represent a potential option in this setting.

Abstract
BACKGROUND Long-term survival benefits of full arterial revascularization with radial artery (RA) used in addition to bilateral internal mammary arteries (BIMA) compared with saphenous vein (SV) used in addition to BIMA has not been clearly defined. METHODS We retrospectively analyzed 660 3-vessel coronary artery disease subjects who received BIMA in addition to either RA (n = 206) or SV (n = 454) grafting in a period between June 1999 and November 2017. After propensity score matching, we obtained 190 matched pairs for analysis. RESULTS In the matched population, in-hospital mortality occurred in 4 patients (1%), with 2 deaths (1.1%) in the BIMA + RA group and 2 deaths (1.1%) in BIMA + SV group (P > .99). The median follow-up time was 9.2 years (interquartile range, 5.6-13 years) with a maximum follow-up time of 18.5 years. There was not a significant difference in long-term survival between the 2 groups over the follow-up period. Survival at 5, 10, and 15 years were 94.8 ± 1.7%, 83.7 ± 3.1%, and 78.6 ± 3.9% in the BIMA + RA group and 96.2 ± 1.4%, 85.1 ± 2.9%, and 80.4 ± 3.6% in the BIMA + SV group (stratified log-rank P = .78). Cox proportional hazard regression model was used to estimate that the use of RA in addition to BIMA did not affect the late mortality (propensity score adjusted hazard ratio, 1.05; 95% confidence interval, 0.62-1.79; P = .83). CONCLUSIONS In a relatively small population of triple-vessel coronary artery disease, the use of RA as a third arterial conduit with BIMA did not confer a long-term survival benefit.

Abstract
Background Plaque composition and morphologic characteristics identified by virtual histology intravascular ultrasound (VH-IVUS) can determine plaques at increased risk of clinical events following percutaneous coronary intervention (PCI) among coronary artery disease (CAD) patients. However, there have been few studies to investigate the relationship between plaque composition of saphenous vein graft (SVG) by VH-IVUS and clinical outcomes in patients with saphenous vein graft disease (SVGD) undergoing PCI. The purpose of this study is to determine whether plaque components and characteristics by VH-IVUS can predict major adverse cardiac events (MACEs) among SVGD patients undergoing PCI. Methods/design This is a prospective cohort study conducted in Tianjin Chest Hospital, China. Participants with SVGD referred for PCI will be invited to participate in this study, and will be followed up at 1, 6, 12, 24 and 36 months post-PCI to assess clinical outcomes. The planned sample size is 175 subjects. We will recruit subjects with SVGD scheduled to receive PCI, aged 18–80 years, with a history of previous coronary artery bypass graft (CABG) surgery more than 1 year ago, and willing to participate in the study and sign informed consent. The composite primary study endpoint is the incidence of MACEs after PCI for SVGD, including death from cardiac causes, non-fatal myocardial infarction, unplanned target lesion revascularization (TLR) and target vessel revascularization (TVR). The primary outcome analysis will be presented as Kaplan-Meier estimates and the primary outcome analysis will be carried out using a Cox proportional hazards regression model. Discussion Once the predictive values of plaque components and characteristics by VH-IVUS on subsequent clinical outcomes are determined among SVGD patients undergoing PCI, an innovative prediction tool of clinical outcomes for SVGD patients undergoing PCI will be created, which may lead to the development of new methods of risk stratification and intervention guidance. Trial registration The study is registered to ClinicalTrials.gov (NCT03175952).

Abstract
It is now 25 years since the radial artery (RA) was reintroduced in coronary surgery. It has evolved into being a significant coronary artery bypass conduit and ranks third in usage after the internal thoracic artery (ITA) and saphenous vein grafts (SVG). Its advantages are that it can be readily and efficiently harvested, is of good length and appropriate size for coronary artery bypass graft (CABG) surgery, is robust and easy to handle, and remains free of atheroma, and there is minimal wound morbidity. The RA must be used judiciously with attention to spasm prophylaxis because of its muscular wall, and by avoiding competitive flow. Its patency is equivalent to the ITAs when placed to similar coronary territories and under similar conditions (stenosis, size, quality) and RA patencies are always superior to those of SVG in both observational and randomized studies-88-90% versus 50-60% at 10 years, and 80-87% versus 25-40% at 20 years. Its use and excellent patencies result in survival results equivalent to bilateral internal thoracic artery (BITA) grafting and always superior to left internal thoracic artery (LITA) +SVG. Typical radial artery multiarterial bypass grafting (RA-MABG) 10-year survivals are 80-90% versus 70-80% for LITA-SVG. In general, for every 100 patients undergoing CABG, 10 more patients will be alive at 10 years post-operatively. The RA also is important in achieving total arterial revascularization, and several reports indicate a further survival advantage for patients having three arterial grafts over two. The RAs are especially useful in diabetic, morbidly obese patients, those with conduit shortage, and leg pathology, and in coronary reoperations. Although the RA has equivalent patencies to the right internal thoracic artery (RITA), it is much more versatile. RAs that have been instrumented by angiography or percutaneous coronary intervention should be avoided. The radial artery has proved to be an excellent arterial conduit, is equivalent to but more versatile than the RITA, and is always superior to SVG. Its use should be part of every coronary surgeon's skill set.

Abstract
BACKGROUND We investigated whether extended arterial grafting with three or more arterial grafts in patients with a left internal thoracic artery to left anterior descending artery graft improves survival in coronary artery bypass graft surgery patients and whether its effects will depend on the extent of coronary artery disease; specifically three-vessel disease (3VD) versus two-vessel disease (2VD). METHODS Fifteen-year mortality was analyzed in 11,931 patients with multivessel disease and primary isolated left internal thoracic artery to left anterior descending artery coronary artery bypass graft surgery with 2 or more grafts. Patients were aged 64.3 ± 10.5 years; 3,484 (29.2%) were women; 2,532 (21.2%) had 2VD and 9,399 (78.8%) had 3VD. Patients were grouped into one single-artery group (n = 6,782, 56.9%; reference group), and two multiple artery groups: two arteries (n = 3,678, 30.8%) and three arteries (n = 1,471, 12.3%). Long-term survival was compared by Kaplan-Meier estimates. Risk-adjusted mortality hazard ratio (HR) with 95% confidence interval (CI) were derived by covariate adjusted Cox regression to quantify multiple artery effects versus one artery in the overall cohort and separately among patients with 2VD and 3VD. RESULTS Radial artery (94%) and right internal thoracic artery (6%) conduits were used for additional arterial grafts. For the entire multivessel cohort, increasing number of arterial grafts was associated with incrementally improved 15-year survival (two arteries HR 0.85, 95% CI: 0.78 to 0.92; three arteries HR 0.75, 95% CI: 0.65 to 0.85). The three arteries versus two arteries comparison was consistent, even if not significant (HR 0.89, 95% CI: 0.77 to 1.03). The benefits derived from additional arterial grafts were more pronounced in case of 3VD (two arteries HR 0.84 95% CI: 0.76 to 0.92; three arteries HR 0.73, 95% CI: 0.63 to 0.84), without survival benefit with 2VD. CONCLUSIONS Our results support the use of extended arterial grafting to maximize long-term coronary artery bypass graft surgery patient survival, especially for 3VD patients.

Abstract
Single arterial left internal thoracic artery (LITA) based coronary artery bypass surgery (LITA-SABG) has been the principal revascularization strategy for over 25 years across all patient demographics. In line with the current emphasis being placed on personalized medicine, which tailors individual, patient-specific therapy to optimize outcomes, coronary artery bypass grafting (CABG) techniques have also evolved to achieve enhanced results among specific groups of patients with coronary artery disease. Most notable has been the development of multi-arterial bypass grafting (MABG) techniques, using either the radial artery (RA) or the right internal thoracic artery (RITA) in conjunction with the LITA, as both techniques have been shown to enhance long term survival of CABG patients. This article reviews the latest data on the long-term outcomes of RA-MABG and considers its impact in various sub-cohorts of CABG that are increasingly being treated by cardiac surgeons. The primary aim of this review is to highlight the advantages of RA-MABG over LITA-SABG and thereby potentiate its adoption into clinical practice. Our secondary aim is to summarize the results of RA-MABG in specific CABG sub-cohorts, to more closely align CABG surgery with the emerging consensus that personalized medicine enhances healthcare value.

Abstract
PURPOSE OF REVIEW To provide a broad overview of the current state of knowledge of coronary artery bypass grafting with bilateral internal thoracic artery (BITA). RECENT FINDINGS There exists a large body of literature from mostly observational studies supporting the use of BITA in patients undergoing coronary artery bypass grafting but selection bias is a major issue with nonrandomized data. The precise method of BITA use does not appear to impact graft patency nor clinical outcomes - in other words, BITA in any configuration appears to be protective. The major downside is the increased risk of sternal complications, which can be mitigated with sternal-sparring adjuncts. The 5-year interim results of the landmark Arterial Revascularization Trial comparing BITA versus single internal thoracic artery did not show a clinical benefit for BITA but the end-of-trial results are pending. Despite wide guideline support for BITA use, uptake in the surgical community remains low and this is likely because of technical and institutional barriers. SUMMARY The published literature thus far supports surgical revascularization with BITA and we eagerly await the 10-year Arterial Revascularization Trial results. The general consensus is that a greater proportion of surgical revascularization should be performed using BITA.

Abstract
PURPOSE OF REVIEW The purpose of this article is to review the strengths and weaknesses of systematic reviews and meta-analyses to inform our current understanding of cardiac surgery. RECENT FINDINGS A systematic review and meta-analysis of a focused topic can provide a quantitative estimate for the effect of a treatment intervention or exposure. In cardiac surgery, observational studies and small, single-center prospective trials provide most of the clinical outcomes that form the evidence base for patient management and guideline recommendations. As such, meta-analyses can be particularly valuable in synthesizing the literature for a particular focused surgical question. Since the year 2000, there are over 800 meta-analysis-related publications in our field. There are some limitations to this technique, including clinical, methodological and statistical heterogeneity, among other challenges. Despite these caveats, results of meta-analyses have been useful in forming treatment recommendations or in providing guidance in the design of future clinical trials. SUMMARY There is a growing number of meta-analyses in the field of cardiac surgery. Knowledge translation via meta-analyses will continue to guide and inform cardiac surgical practice and our practice guidelines.

Abstract
This review was undertaken to understand the dynamics that have shaped our current treatment of women who undergo coronary artery bypass grafting (CABG) and summarize the current literature on surgical revascularization in women. There has been improved access to CABG over the past several decades. Despite this, compared with men, CABG in women involves fewer grafts and less frequent use of arterial grafts, the latter having improved long-term patency compared with saphenous vein grafts. We attempt to determine whether the adverse clinical profile of women, when referred for CABG is responsible for this finding. Female coronary anatomy and pathophysiology are reviewed and an attempt is made to understand how this might affect decisions of selection and outcome measures post CABG. We review the short-term, long-term, and quality of life outcomes in women. These data are taken from large databases, as well as from more recent publications. Randomized controlled trial data and meta-analytic data are used when available. Differential use of and outcomes of surgical strategies, including off-pump CABG and total arterial revascularization, are contrasted with those in men. This review shows that there continues to be widespread differences in surgical approach to coronary artery disease in female vs male patients. We provide evidence suggestive of the existence of issues specific to women that affect selection for surgical procedures and outcomes in women. More work is required to understand the reason for these differences and how to optimize sex-specific outcomes.

Abstract
The number of patients requiring hemodialysis is continuously increasing around the world. Hemodialysis affects patient quality of life and it is also associated with a higher risk for cardiovascular events. In addition to traditional risk factors for cardiovascular events such as hypertension, hyperlipidemia, and diabetes, hemodialysis is associated with hyperphosphatemia, chronic inflammation, vascular calcification, and anemia which accelerate atherosclerosis, vascular stiffness, and cardiac ischemia. Treatment strategy for coronary revascularization in this progressive disease remains controversial. However, a systematic treatment including medical therapy and complete revascularization through a less invasive strategy should be considered in addressing this problem. This review discusses the epidemiology, vascular pathology and current treatment options in patients with end-stage renal disease requiring coronary revascularization.
