Abstract
Coronary bypass grafting for patients on chronic dialysis has increased the risk of operative mortality, and long-term survival is considered poor. Thirty-three patients dependent on dialysis undergoing coronary bypass grafting were analyzed. The 33 patients were divided into two groups according to the strategy for renal support. In group A, 12 patients underwent continuous hemofiltration (CHF) during and after cardiopulmonary bypass and CHF in an intensive care unit (ICU) and then returned to regular dialysis. In group B, 21 patients underwent modified ultrafiltration (UF) immediately after cardiopulmonary bypass and continuous hemodialysis and filtration in an ICU with early reinstitution of regular dialysis. Two patients died in group A, and there were no operative deaths in group B (17% vs. 0%, p < 0.05). Three patients in group A and one patient in group B had bleeding complications requiring reoperation (25% vs. 5%, p < 0.05). Three patients in group A and one patient in group B needed intraaortic balloon pump (IABP) support postoperatively (25% vs. 5%, p < 0.05). Four patients in group A and one in group B required long-term ventilation of more than 3 days (33% vs. 5%, p < 0.05). There were five patients in group A and two patients in group B requiring long-term ICU stay of more than 4 days (41% vs. 10%, p < 0.05). Postoperative blood loss within 24 hours was 1310 ml in group A and 623 ml in group B (p < 0.05). Transfusion requirements were 9.3 units in group A and 3.0 units in group B (p < 0.05). During follow-up, the long-term survival, New York Heart Association (NYHA) functional class, and incidence of recurrent angina were considered favorable in both groups. Cardiac event-free rates after surgery at 1, 3, and 5 years were 88%, 73%, and 67%, respectively. The operative mortality, morbidity, and long-term survival for dialysis dependent patients were reasonably acceptable. As renal support, modified UF can play an important role in reducing bleeding complications, shortening the ICU stay, and decreasing blood loss and transfusion requirements.

Abstract
Management issues in acute coronary syndromes (ACSs) with regard to patients with renal insufficiency or failure are complex. Renal patients have a greater risk for bleeding compared with those with normal renal function because of prolonged bleeding time and platelet dysfunction. Some of the drugs used have significant renal excretion, such as the glycoprotein IIb/IIIa receptor antagonists. Additionally, thrombolytics are underused, which contributes to the delay in instituting immediate treatment of acute myocardial infarction. Clinical data regarding the optimum management of ACSs in renal patients are still lacking. In this article, we review the available data on the use of antithrombotic agents, particularly in patients with renal impairment.

Abstract
Ischemic heart disease is the most common cause of death in patients with chronic kidney disease (CKD). Patients with CKD who develop an acute coronary syndrome (ACS) have a poor prognosis, with >70% mortality at 2 years. Despite this heavy burden of disease, the optimal management of ACS in this patient population is unknown. Our goal was to compare the effect of coronary revascularization or medical therapy alone on the long-term survival of patients with CKD presenting with ACS. From 1990 to 1998, data were prospectively collected on 4,758 patients admitted to a coronary care unit with the diagnosis of ACS. Of these, 3,104 had preserved renal function, and 1,654 had significant renal dysfunction, as defined by the National Kidney Foundation in the Kidney Disease Outcomes Quality Initiative classification of kidney function as an estimated glomerular filtration rate of <60 ml/min/1.73 m(2). Long-term survival was assessed and outcomes were compared according to whether patients were treated with medical therapy alone or if they underwent a percutaneous or surgical revascularization procedure. Follow-up information was available in 99% of the patients up to 8 years after the index hospitalization. Of the 1,654 patients with significant renal dysfunction, 64 underwent coronary artery bypass surgery, 232 underwent percutaneous coronary revascularization, 280 underwent a diagnostic cardiac catheterization and were subsequently treated medically, whereas 1,078 were treated with medical therapy alone. Percutaneous coronary revascularization was associated with superior long-term survival. In conclusion, patients with severe CKD and ACS had improved long-term survival when treated with percutaneous coronary revascularization.

Abstract
The clinical results of percutaneous transluminal coronary rotational atherectomy (PTCRA) in dialysis patients were retrospectively evaluated in comparison with coronary artery bypass grafting (CABG). From 1997 to 2001, 44 consecutive dialysis patients with 61 lesions underwent PTCRA and 55 consecutive dialysis patients underwent CABG. The initial success rate of PTCRA was 98%. The PTCRA group had a shorter hospital stay (13+/-17 vs 60+/-35 days, p=0.0001) and a lower rate of complications (11% vs 42%, p=0.001) than the CABG group. Although neither event-free survival without death nor myocardial infarction (MI) was significantly different between the CABG and PTCRA groups during the mean follow-up period of 21+/-14 months, 20 patients (45%) in the PTCRA group needed repeat revascularization of the target lesion. In conclusion, PTCRA may be a safe alternative modality for revascularization of high-risk CABG candidates, with excellent short-term results although the long-term outcome is inferior to that of CABG because of the higher restenosis rate.

Abstract
Although renal failure has classically been associated with a bleeding tendency, thrombotic events are common among patients with end-stage renal disease (ESRD). A variety of thrombosis-favoring hematologic alterations have been demonstrated in these patients. In addition, "nontraditional" risk factors for thrombosis, such as hyperhomocysteinemia, endothelial dysfunction, inflammation, and malnutrition, are present in a significant proportion of chronic dialysis patients. Hemodialysis (HD) vascular access thrombosis, ischemic heart disease, and renal allograft thrombosis are well-recognized complications in these patients. Deep venous thrombosis and pulmonary embolism are viewed as rare in chronic dialysis patients, but recent studies suggest that this perception should be reconsidered. Several ESRD treatment factors such as recombinant erythropoietin (EPO) administration, dialyzer bioincompatibility, and calcineurin inhibitor administration may have prothrombotic effects. In this article we review the pathogenesis and clinical manifestations of thrombosis in ESRD and evaluate the evidence that chronic renal failure or its management predisposes to thrombotic events.

Abstract
BACKGROUND The optimal method of coronary revascularization in dialysis patients is controversial. The purpose of this study was to compare the long-term survival of dialysis patients in the United States after PTCA, coronary stenting, or CABG. METHODS AND RESULTS Dialysis patients hospitalized from 1995 to 1998 for first coronary revascularization procedures after renal replacement therapy initiation were identified from the US Renal Data System database. All-cause and cardiac survival was estimated by the life-table method and compared by the log-rank test. The impact of independent predictors on survival was examined in a Cox regression model. The in-hospital mortality was 8.6% for 6668 CABG patients, 6.4% for 4836 PTCA patients, and 4.1% for 4280 stent patients. The 2-year all-cause survival (mean+/-SEM) was 56.4+/-1.4% for CABG patients, 48.2+/-1.5% for PTCA patients, and 48.4+/-2.0% for stent patients (P<0.0001). After comorbidity adjustment, the relative risk (RR) for CABG (versus PTCA) patients was 0.80 (95% CI 0.76 to 0.84, P<0.0001) for all-cause death and 0.72 (95% CI 0.67 to 0.77, P<0.0001) for cardiac death. For stent (versus PTCA) patients, the RR was 0.94 (95% CI 0.88 to 0.99, P=0.03) for all-cause death and 0.92 (95% CI 0.85 to 0.99, P=0.04) for cardiac death. In diabetic (versus PTCA) patients, the RR for CABG surgery was 0.81 (95% CI 0.75 to 0.88, P<0.0001) for all-cause death and 0.71 (95% CI 0.64 to 0.78, P<0.0001) for cardiac death, and the RR for the stent procedure was 0.99 (95% CI 0.91 to 1.08, P=NS) for all-cause death and 0.99 (95% CI 0.89 to 1.11, P=NS) for cardiac death. CONCLUSIONS In this retrospective study, dialysis patients in the United States had better long-term survival after CABG surgery than after percutaneous coronary intervention. Stent outcomes were relatively worse in diabetic patients. Our data support the need for large clinical registries and prospective trials of surgical and percutaneous coronary revascularization procedures in dialysis patients.

Abstract
BACKGROUND Coronary artery bypass grafting (CABG) for hemodialysis patients is high risk compared with other patient groups. The aim of this study was to analyze the potential benefits of off-pump CABG for hemodialysis patients. METHODS From April 1994 through December 2000, 26 hemodialysis patients underwent CABG. The off-pump group consisted of 15 patients operated on without a pump and the on-pump group consisted of 11 patients operated on with a pump. RESULTS There was no difference between the two groups with regard to mean age, mean number of diseased vessels and mean number of anastomoses per patient. No patient died in either group during hospitalization. The postoperative complication rate was low in both groups. The postoperative ventilation time was shorter in the off-pump group (8.5 vs 26.1 hours, p < 0.001, respectively [off-pump group vs on-pump group]). The length of ICU stay was shorter in the off-pump group (1.7 vs 3.5 days, p = 0.01, respectively [off-pump group vs on-pump group]). The medial cost was lower in the off-pump group (26,200.80 dollars versus 44,024.10 dollars p = 0.0001 respectively [off-pump group vs on-pump group]). CONCLUSIONS Off-pump CABG provided excellent less-invasive cardiac surgical results for dialysis patients.

Abstract
BACKGROUND Ischemic heart disease is the major cause of death in patients with end-stage renal disease. The high prevalence of coronary artery disease results in a rising number of dialysis patients requiring myocardial revascularisation. OBJECTIVE The objective of this study was to compare the outcomes of recurrent angina, myocardial infarction, rate of reinterventions and cardiovascular death following percutaneous coronary angioplasty (PTCA) or coronary artery bypass grafting (CABG) in patients with end-stage renal disease. PATIENTS AND METHODS In a retrospective investigation 40 patients with chronic renal failure undergoing primarily PTCA and 65 patients undergoing CABG were included. Both groups were comparable for gender, duration on dialysis and the number of cardiovascular risk factors per patient. Patients undergoing PTCA were younger (53 +/- 12 years vs. 57 + 8 years; p < 0.05) and more often diabetics (30% vs. 14%; p < 0.05). RESULTS Most patients in both groups had a multi-vessel disease (95% in the CABG group vs. 74% in the PTCA group), in the CABG group there were significantly more patients with a triple-vessel disease (62% with vs. 40% in the PTCA group; p < 0.01), PTCA was primarily successful in 95% of the patients while complete revascularization was achieved in 88% of patients undergoing CABG. The perioperative mortality after CABG was 4.8% as compared to none after interventional revascularisation. The cumulative freedom of angina after 6, 12 and 24 months after intervention was significantly lower after PTCA (54%, 40%, 29%) than after bypass grafting (97%, 94%, 90%, p < 0.001). The frequency of reinterventions following PTCA was significantly higher compared to patients following CABG (p < 0.001). After PTCA 15 patients needed further revascularisations, 8 of them underwent CABG, whereas after CABG only two patients required additional myocardial revascularisation. There was no significant difference in the overall mortality between both groups; the survival rate after 12 and 24 months was 95% and 82% after PTCA and 93% and 86% after CABG, respectively. CONDITION Although patients receiving CABG had a more severe coronary artery disease the overall mortality was comparable and clinical and functional outcome was improved compared to patients after coronary angioplasty.

Abstract
To test the hypothesis that coronary revascularization improves long-term prognosis in patients with hemodialysis, 80 of 121 patients (66%) on maintenance hemodialysis who had undergone initial coronary angiography had bypass surgery, catheter angioplasty, or both between 1983 and 1999. Multivessel disease was more frequent (p=0.01) and the duration of hemodialysis therapy was shorter (p=0.01) in patients with diabetes (n=61), than in nondiabetic patients (n=60). Of the patients who underwent revascularization, complete revascularization was achieved in 75% of those with diabetic nephropathy (30/40) and 83% in a similar number of nondiabetic patients (33/40). The 5-year survival rate from initiation of hemodialysis was 79% in diabetic and 96% in non-diabetic patients (p<0.01), exceeding published Japanese (53% vs 70%) and US (26% vs 60%) survival rates. When survival was studied from the date of revascularization, predictors of outcome were age and achievement of complete revascularization. Surprisingly, diabetes was not a predictor of survival outcome. Complete revascularization improves long-term survival in both diabetic and nondiabetic patients.

Abstract
BACKGROUND Multiple studies have demonstrated a relationship between creatine kinase-MB (CK-MB) elevation after percutaneous coronary intervention (PCI) and increased late mortality within the general population. Because CK-MB is frequently elevated in renal disease even in the absence of myocardial injury, the clinical significance of CK-MB elevation after PCI in patients with renal insufficiency has been questioned. METHODS We sought to examine the association between elevated CK-MB after PCI and late mortality in 190 consecutive patients with chronic renal insufficiency (serum creatinine > or =2.0 mg/dL) undergoing PCI at the Cleveland Clinic between January 1997 and March 2000. Of the total group, 20 patients undergoing PCI for acute myocardial infarction, cardiogenic shock, or both were excluded. Follow-up was 99.4% complete at a mean duration of 24.8 +/- 11.2 months (range 5-43 months). RESULTS CK-MB elevation above the upper limit of normal after intervention was detected in 33 patients (19.4%). Baseline characteristics were not significantly different between the CK-MB elevation group and the normal CK-MB group. Late mortality, however, was significantly higher among patients with postprocedural CK-MB elevation (36.4% vs 17.5%, P =.017). Cox proportional hazard model revealed CK-MB elevation as an independent predictor of late mortality (hazard ratio 2.44, 95% CI 1.14-5.24, P =.02), in addition to New York Heart Association class (hazard ratio 1.35, 95% CI 1.05-1.73, P =.02). CONCLUSIONS This analysis of patients with chronic renal insufficiency undergoing PCI suggests that postprocedural CK-MB elevation is an independent predictor of late mortality even in the presence of renal dysfunction.

Abstract
OBJECTIVES We sought to determine the effect of varying degrees of renal insufficiency on death and cardiac events during and after a percutaneous coronary intervention (PCI). BACKGROUND Patients with end-stage renal disease have a high mortality from coronary artery disease. Little is known about the impact of mild and moderate renal insufficiency on clinical outcomes after PCI. METHODS Cardiac mortality and all-cause mortality were determined for 5,327 patients undergoing PCI from January 1, 1994, to August 31, 1999, at the Mayo Clinic, based on the estimated creatinine clearance or whether the patient was on dialysis. RESULTS In-hospital mortality was significantly associated with renal insufficiency (p = 0.001). Even after successful PCI, one-year mortality was 1.5% when the creatinine clearance was > or =70 ml/min (n = 2,558), 3.6% when it was 50 to 69 ml/min (n = 1,458), 7.8% when it was 30 to 49 ml/min (n = 828) and 18.3% when it was < 30 ml/min (n = 141). The 18.3% mortality rate for the group with < 30 ml/min creatinine clearance was similar to the 19.9% mortality rate in patients on dialysis (n = 46). The mortality risk was largely independent of all other factors. CONCLUSIONS Renal insufficiency is a strong predictor of death and subsequent cardiac events in a dose-dependent fashion during and after PCI. Patients with renal insufficiency have more baseline cardiovascular risk factors, but renal insufficiency is associated with an increased risk of death and other adverse cardiovascular events, independent of all other measured variables.

Abstract
The metabolic abnormalities associated with chronic renal failure and complications of the dialysis procedure present unique challenges in critical care medicine. Understanding how renal failure impacts the development and management of cardiovascular disease, bleeding tendencies, infection, and malnutrition is necessary to provide optimal care for these patients. The recognition of ESRD as a state of chronic inflammation and increased oxidative stress ultimately should lead to more effective treatment approaches for several of the comorbid conditions common in this patient population.

Abstract
QT dispersion (the difference between maximum and minimum QT across the 12-lead electrocardiogram [ECG]), which reflects regional variations in ventricular repolarization, is a predictor of arrhythmia and cardiovascular mortality. The present study was undertaken to assess the difference in QT dispersion between uremic and nonuremic patients with acute myocardial infarction (AMI) and its relationship to post-AMI clinical outcome. Twelve-lead ECG recordings were obtained the first and third days after the onset of AMI in 21 uremic and 21 nonuremic patients. QT intervals were measured on 12-lead ECGs and corrected by heart rate (QTc). Our findings show that uremic patients with AMI had greater QTc dispersion (84 +/- 35 versus 55 +/- 15 milliseconds; P < 0.001), a greater 1-year mortality rate (48% versus 18%; P = 0.003), and underwent fewer reperfusion therapies (5 of 21 versus 17 of 21 patients; P = 0.002) compared with nonuremic patients with AMI. Patients with AMI who died had greater QTc dispersion than those who survived (102 +/- 40 versus 67 +/- 40 milliseconds; P = 0.015). An optimal QTc dispersion cutoff value of 60 milliseconds had a sensitivity of 100% and specificity of 55% in predicting 1-year mortality in uremic patients with AMI. Uremic patients with AMI administered thrombolytic therapies (n = 5) had reduced 1-year mortality rates (0% versus 63%; P = 0.003) and shortened QTc dispersion from days 1 to 3 (changes in QTc dispersion between days 1 and 3, 29% +/- 9% decrease versus 13% +/- 5% increase; P = 0.001) compared with those without therapies (n = 16). Our findings suggest that greater QT dispersion is associated with greater total mortality, and thrombolytic therapies could reduce QTc dispersion and mortality in uremic patients with AMI. It is prudent to refine our current management regimen for uremic patients with AMI to improve the poor clinical outcome.

Abstract
The clinical outcome of patients with chronic renal failure (CRF) who undergo percutaneous coronary intervention (PCI) has not been systematically evaluated in a large cohort of patients. We retrospectively analyzed the in-hospital and 1-year clinical outcomes of 10,076 consecutive patients who underwent PCI between January 1994 and December 1997. A total of 95 patients (0.9%) had end-stage renal disease (ESRD) on dialysis, 786 patients (7.8%) had CRF, and 9,125 patients (90.6%) had normal renal function. Despite an angiographic success rate of 97% in all three groups, in-hospital mortality was significantly higher among patients with renal disease, whether they were on dialysis or not, when compared to patients without renal dysfunction (6.8% vs. 4.2% vs. 0.9%; P < 0.0001). At 1-year follow-up, mortality rate was 48.8% for ESRD, 25.7% for patients with CRF, and 5.5%, for patients without renal dysfunction (P < 0.0001). By multivariate analysis, high left ventricular ejection fraction and creatinine clearance were associated with decreased late mortality (OR = 0.84 and 0.95; P < 0.0001), whereas ESRD (OR = 3.65; P = 0.0002), non-Q-wave myocardial infarction (OR = 2.21; P < 0.0001), diabetes mellitus (OR = 1.99; P < 0.0001), and CRF (OR = 1.74; P = 0.003) were independent correlates of increased late mortality. Therefore, PCI in patients with impaired renal function, whether on dialysis or not, is associated with poor in-hospital and 1-year survival.

Abstract
This retrospective study examined the utilization of coronary stent placement versus PTCA in hemodialysis patients with obstructive coronary disease. Prior studies have demonstrated suboptimal results with PTCA owing primarily to high rates of restenosis. We identified 19 hemodialysis patients who received a percutaneous coronary intervention who were matched with individuals without renal failure undergoing same vessel revascularization. Our study found that 71% of hemodialysis patients receiving PTCA had a recurrent cardiac event defined by subsequent angina, myocardial infarction, or cardiac death. At follow-up, 30% of patients who received stent placement had recurrent cardiac events. Intracoronary stent placement is both safe and feasible and produces more favorable clinical outcomes in the management of coronary disease in hemodialysis patients.

Abstract
BACKGROUND Percutaneous balloon angioplasty has become a well-established and routine procedure for coronary revascularization of haemodialysis patients with coronary artery disease. However, the incidence of restenosis after balloon angioplasty is significantly higher in haemodialysis patients than in the general population. We performed a retrospective study comparing balloon angioplasty with coronary stenting in haemodialysis patients. We evaluated the long-term clinical and angiographic outcome after successful percutaneous coronary revascularization in haemodialysis patients. METHODS A total of 103 consecutive haemodialysis patients (123 lesions) underwent procedurally and clinically successful percutaneous revascularization. Patients were treated with three different strategies: (i) balloon angioplasty in 55 patients (69 lesions); (ii) coronary stenting with balloon angioplasty in 23 patients (25 lesions); and (iii) coronary stenting with rotational atherectomy in 25 patients (29 lesions) who had severely calcified stenotic coronaries. RESULTS The rates of in-hospital mortality were similar in the three groups. The 1-year incidence of overall events and major adverse cardiac events (MACE) were significantly higher in the balloon group than in the stent with/without rotational atherectomy groups (75% vs 36 and 28%, P<0.01; 71% vs 32 and 28%, P<0.01). Use of coronary stenting (relative risk=0.006, P<0.001) and the presence of calcified coronary lesion (relative risk=68.2, P<0.001) were independent predictors of the 1-year MACE-free survival after percutaneous revascularization. The 3-year MACE-free survival rate was significantly lower in the balloon group than in the stent with/without rotational atherectomy groups (11% vs 33 and 47%, P<0.005 and P<0.001). CONCLUSIONS This study shows that coronary stenting reduces the incidence of MACE in haemodialysis patients with/without calcified coronary lesions. Moreover, coronary stenting reduces the restenosis rate of both complex and restenotic lesions, and rotational atherectomy prior to coronary stenting reduces the restenosis rate of the severely calcified coronary lesions. These results suggest that coronary stenting with/without rotational atherectomy has led to an improved long-term outcome in the haemodialysis patients with coronary artery disease.

Abstract
OBJECTIVE Coronary artery bypass grafting (CABG) under a beating heart is reported to be less invasive and promise earlier recovery. This study was performed to evaluate the efficacy of off-pump CABG in patients with end-stage renal failure. METHODS Isolated CABG was performed on 40 hemodialysis patients at Shin-Tokyo Hospital Group between September 1, 1993, and December 31, 2000. Among them, off-pump CABG was performed in 16 and on-pump CABG in 24. Their preoperative, perioperative, and follow-up data were retrospectively collected. RESULTS Patient's demographics and coronary risk factors were similar in off-pump and on-pump groups. The mean number of bypass grafts was 1.9 +/- 1.1 in the off-pump group and 2.8 +/- 1.1 in the on-pump group (P < 0.05). Blood transfusion was significantly less frequent in the off-pump group than in on-pump group. Postoperative complications were more frequently observed in the on-pump group (7.1% off-pump vs 25.0% on-pump). There were two hospital deaths in the on-pump group and none in the off-pump group. Postoperative intubation time, ICU stay, and hospital stay were significantly shorter in the off-pump group than in the on-pump group. Although follow-up period was short (1.1 +/- 0.7 years), no cardiac events occurred in the off-pump group. CONCLUSIONS Off-pump CABG for hemodialysis patients is safe and useful and it enables early recovery. Postoperative cardiac events were controlled effectively during the short period of follow-up.

Abstract
OBJECTIVE To assess the efficacy and safety of cardiopulmonary bypass during coronary artery bypass grafting (CABG) in dialysis patients. METHODS AND RESULTS Sixty four isolated CABG patients who underwent on cardiopulmonary bypass and whose intraoperative body weight gains were accurately measured were studied retrospectively. The mean intraoperative body weight gain was 2.61 +/- 0.9 kg/m2 in the study group and 1.06 +/- 0.6 kg/m2 in controls, i.e.) 100 patients selected at random from CABG patients during the same period using cardiopulmonary bypass without chronic renal faulure, showing a statistically significant difference. Complete revascularization was successful in 98% of patients. Postoperative nonlethal complications involved brain infarction in 1 patient (1.7%), reintubation in 1 (1.7%), and paralytic ileus in 2 (3.4%). All were successfully extubated within 24 hours of surgery, and no sternal wound complications were found. Hospital mortality was 6.3% (4/64). Actuarial survival rates at 3, 5 and 8 years including all deaths were 90%, 70% and 56%, and estimated by cardiac deaths were 95%, 90%, and 90% respectively. Cardiac event free rates were 90%, 73% and 61% at 3, 5 and 8 years after CABG. CONCLUSIONS In CABG for dialysis patients, the use of cardiopulmonary bypass demonstrates significant merits, and may expect long-term survival with minimal postoperative complications.

Abstract
BACKGROUND Patients with end-stage renal disease have an increased risk of developing coronary artery disease (CAD). The cardiovascular mortality of dialysis patients is 10-15 times higher compared with the general population. The aim of our study was to evaluate the morphological progression of coronary arteriosclerosis in this cardiovascular high-risk group by visual assessment and quantitative coronary angiography. Methods and results. In 26 patients with chronic renal failure (age, 47+/-11 years; 15 male; duration of dialysis, 23+/-25 months) the severity of CAD and degree of coronary stenoses were assessed in two coronary angiograms after a mean follow-up interval of 30+/-15 months (12-60). Baseline angiography revealed CAD in 13/22 patients (59%). The second angiography was performed as screening procedure prior to renal transplantation (n=20) and/or as follow-up angiography after coronary angioplasty (n=10). Visual assessment showed a progression defined by the development of haemodynamically relevant stenosis of >50% luminal diameter in 13 patients. Quantitative angiographic evaluation was performed in a total of 45 segments showing >25% narrowing at the second angiogram. A progression (>15% luminal reduction) was found in 17 of 45 segments, a new lesion (initial luminal diameter <20%) was detected in nine segments, resulting in progression or new lesion in 16 patients (62%). Patients with or without progression did not differ in age, duration of dialysis treatment, number of cardiovascular risk factors, or serum total cholesterol and fibrinogen levels. After percutaneous transluminal coronary angioplasty (PTCA) a restenosis was seen in seven of 16 primarily successfully dilated segments. After the second angiography, myocardial revascularization was performed in eight patients (1 PTCA, 7 coronary artery bypass graft). CONCLUSIONS Patients with end-stage renal disease have a high prevalence of CAD. In line with the clinical course, CAD patients on maintenance dialysis undergo rapid angiographic progression of CAD, which results in a high rate of subsequent myocardial revascularizations.

Abstract
BACKGROUND Balloon coronary angioplasty has been reported to be ineffective in patients treated for end stage renal disease because of a high restenosis rate. OBJECTIVE To compare the clinical outcome following coronary angioplasty with provisional stenting in dialysis versus non-dialysis patients. DESIGN A case-control study. PATIENTS Of 1428 consecutive patients who underwent coronary angioplasty, 100 (7%) were being treated for end stage renal disease. These were compared with 100 control patients matched for age, sex, coronary lesions, presence of diabetes mellitus, and rate of coronary stenting (40%). MAIN OUTCOME MEASURES In-hospital and one year clinical outcome. RESULTS The rates of procedural success (90% v 93%), in-hospital mortality (1% v 0%), stent thrombosis (0% v 0%), and Q wave myocardial infarction (0% v 1%) were similar in dialysis and non-dialysis patients. One year clinical outcome after coronary angioplasty was similar in the two groups in terms of clinical restenosis (31% v 28%) and myocardial infarction (6% v 2%), but cardiac death was more common in dialysed patients (11% v 2%, p < 0.03). CONCLUSIONS Dialysis does not increase the risk of clinical restenosis after coronary angioplasty with provisional stenting. Coronary angioplasty is a safe and effective therapeutic procedure in selected dialysis patients with culprit lesions accessible to stenting. However, the one year survival is reduced in this high risk population.

Abstract
Patients with renal failure undergoing percutaneous coronary intervention (PCI) experience reduced procedural success rates and increased in-hospital and long-term follow-up major adverse cardiac events. This study was designed to determine whether the severity of preprocedural renal failure influences the outcomes of patients with renal failure undergoing PCI. We compared the immediate and long-term outcomes of 192 patients with mild renal failure (creatinine 1.6 to 2.0 mg/dl, mean 1.76) with those of 131 patients with severe renal failure (creatinine >2.0 mg/dl, mean 2.90), selected from 3,334 consecutive patients undergoing PCI between 1994 and 1997. Although the overall population with renal failure represents a high-risk group, the severe renal failure cohort had a higher incidence of hypertension, multivessel disease, prior coronary bypass surgery, vascular disease, and congestive heart failure (all p values <0.05), yet had similar angiographic characteristics. Procedural success was higher in the group with severe renal failure (93.7% vs 87.7%, p = 0.04). There were no statistically significant differences in in-hospital mortality (11.5% vs 9.9%, p = 0.7), Q-wave myocardial infarction (0.5% vs 0%, p = 0.4), emergent bypass surgery (0% vs 0%, p = 1.0), and in-hospital major adverse cardiac events (11.5% vs 9.9%, p = 0.7) between the mild and severe renal groups, respectively. Kaplan-Meier analyses showed no statistically significant difference in long-term survival (log rank test, p = 0.1) or event-free survival (log rank test, p = 0.3) between the 2 groups. Finally, creatinine was not identified as an independent predictor of in-hospital or long-term follow-up major adverse cardiac events. In our high-risk population, patients with mild renal insufficiency undergoing PCI experience major adverse outcomes in the hospital and at long-term follow-up similar to those of patients with severe renal failure.

Abstract
Cardiovascular disease accounts for almost half of the total mortality in patients with end stage renal disease (ESRD). It has recently been debated whether coronary revascularization has the same rate of risks and successes in this cohort of patients compared to patients without renal disease. Since 1991, 17 dialysis patients were submitted to coronary revascularization in our center. Seven patients were following peritoneal, 10 hemodialytic treatment. Four patients were submitted to percutaneous transluminal coronary angioplasty (PTCA) and 13 to surgical revascularization (CABG). In 2 patients the coronary lesion was unique, in the others stenosis of multiple vessels were found. Six patients were diabetic. The mean age at the onset of the coronary artery disease (CAD) was 57.17 +/- 11.6 years. The mean time elapsed from the onset of the CAD and the performance of the PTCA or CABG was 30.1 +/- 35.4 months. The mean time from beginning of dialysis treatment to revascularization was 48.2 +/- 39.6 months. Mean hemoglobin values were 9.7 +/- 1 g/dL, mean phosphorus values were 5.2 +/- 8.7 mg/dL, mean cholesterol values were 211 +/- 49.5 mg/dL. The procedure was technically successful in all patients. Mean survival was 25.09 +/- 28.12 months. Twelve patients died, 5 of whom within one month. Survival at one month was 70.5%, at 6 months 58.8%, at one year 52.9%, at 2 years 47%. There was neither significant difference patients submitted to PTCA and those submitted to CABG, nor between diabetic and non-diabetic patients. In conclusion, coronary revascularization in our experience is a high risk procedure in dialysis patients. The reasons for this could be the severe general conditions of these patients affected with diffuse vasculopathy and the long time elapsed since the onset of the ischemic cardiopathy. Thus, our results could suggest the opportunity of performing earlier screening of coronary situation and revascularization treatment in CAD dialysis patients.

Abstract
UNLABELLED It is well known that dialysis-dependent renal failure increases the likelihood of a poor outcome following cardiac surgery. However, it is not known whether non-dialysis-dependent mild renal insufficiency also influences clinical outcome. Fifty-five patients with non-dialysis-dependent renal insufficiency undergoing coronary artery bypass grafting (CABG) (Renal group: serum creatinine level >1.5 mg/dl) were enrolled. These patients were then matched on prognostic variables to 148 patients with normal renal function ( CONTROL GROUP serum creatinine level <1.5 mg/dl). The early postoperative clinical results showed that patients in the Renal group were more likely to develop postoperative renal failure (18% vs 1%: p=0.0002) and hemorrhage requiring re-exploration (11% vs 2%; p=0.01). Total morbidity was significantly higher in the Renal group (40% vs 22%; p=0.01). Multivariate analysis revealed that the Renal group was the second most important predictor of morbidity (odds ratio (OR) =2.2) behind left ventricular dysfunction (OR=2.9). The Renal group was also the second most important predictor of postoperative renal failure (OR=12.5). Therefore, non-dialysis-dependent mild renal insufficiency also increases the risk of morbidity following CABG.

Abstract
BACKGROUND Although dialysis patients are undergoing CABG with increasing frequency, large studies specifically comparing patient characteristics and procedure-related risks in this population have not been performed. METHODS AND RESULTS We conducted a regional prospective cohort study of 15,500 consecutive patients undergoing CABG in northern New England from 1992 to 1997. We used multiple logistic regression analysis to examine associations between preoperative dialysis-dependent renal failure and postoperative events and to adjust for potentially confounding variables. The 279 dialysis-dependent renal failure patients (1.8%) were 4.4 times more likely to experience in-hospital mortality than were other CABG patients (12.2% versus 3.0%, respectively; P:<0.001). Dialysis-dependent renal failure patients were older and had more comorbidities and more severe cardiac disease than did other CABG patients. After adjusting for these factors in multivariate analysis, however, dialysis-dependent renal failure patients remained 3.1 times more likely to die after CABG (adjusted odds ratio [OR] 3.1, 95% CI 2.1 to 4.7; P:<0.001). Dialysis-dependent renal failure patients compared with other CABG patients also had a substantially increased risk of postoperative mediastinitis (3.6% versus 1.2%, respectively; adjusted OR 2.4, 95% CI 1.2 to 4.7; P:=0.011) and postoperative stroke (4.3% versus 1.7%, respectively; adjusted OR 2. 1, 95% CI 1.1 to 3.9; P:=0.016), even after controlling for potentially confounding variables. Risks of reexploration for bleeding were similar for patients with and without dialysis-dependent renal failure. CONCLUSIONS Preoperative dialysis-dependent renal failure is a strong independent risk factor for in-hospital mortality and mediastinitis after CABG.

Abstract
BACKGROUND Patients with end-stage renal disease undergoing conventional balloon angioplasty have reduced procedural success and increased complication rates. This study was designed to determine the immediate and long-term outcomes of patients with varying degrees of renal failure undergoing percutaneous coronary intervention in the current device era. METHODS AND RESULTS We compared the immediate and long-term outcomes of 362 renal failure patients (creatinine >1.5 mg/dL) with those of 2972 patients with normal renal function who underwent percutaneous coronary intervention between 1994 and 1997. Patients with renal failure were older and had more associated comorbidities. They had reduced procedural success (89.5% versus 92.9%, P:=0.007) and greater in-hospital combined major event (death, Q-wave myocardial infarction, emergent CABG; 10.8% versus 1.8%; P:<0.0001) rates. Renal failure was an independent predictor of major adverse cardiac events (MACEs) (OR, 3.41; 95% CI, 1.84 to 6.22; P:<0.00001). Logistic regression analysis identified shock, peripheral vascular disease, balloon angioplasty strategy, and unstable angina as independent predictors of in-hospital MACEs in the renal group. Compared with 362 age- and sex-matched patients selected from the control group, patients with renal failure had a lower survival rate (27.7% versus 6.1%, P:<0.0001) and a greater MACE rate (51% versus 33%, P:<0.001) at long-term follow-up. Cox regression analysis identified age and PTCA strategy as independent predictors of long-term MACEs in the renal group. Finally, within the renal failure population, the dialysis and nondialysis patients experienced remarkably similar immediate and long-term outcomes. CONCLUSIONS Although patients with renal failure can be treated with a high procedural success rate in the new device era, they have an increased rate of major events both in hospital and at long-term follow-up. Nevertheless, utilization of stenting and debulking techniques improves immediate and long-term outcomes.

Abstract
Atherosclerotic renal arterial disease (ARAD) is becoming a more important cause of end-stage renal failure. Diagnosis is more easily achieved because of greater clinical suspicion and more refined screening tools. However, the medical and interventional management of patients with ARAD is not well defined in the literature because there have been few randomized trials. Because the use of angiotensin-converting enzymes (ACE) inhibitors, and more recently angiotensin-antagonists, has become much more widespread, it is inevitable that we should, knowingly or not, give these drugs to patients with ARAD. We describe 2 case studies in which the angiotensin-antagonist irbesartan was given to 2 patients with effectively single-functional kidneys after successful renal arterial radiologic intervention. The rationale for the use of irbesartan was to control BP, which had not responded to the initial arterial intervention, and took place in patients both refractory to, and intolerant of, many other anti-hypertensive drugs. Irbesartan successfully and safely reduced systemic BP, measured by use of ambulatory BP, without prejudicing renal function (measured by use of individual kidney function GFR).

Abstract
Although patients with end-stage renal disease (ESRD) are at high risk for restenosis that requires repeat revascularization after balloon angioplasty, their restenosis rate after coronary stenting is still unknown. Over a 4-year period, we performed coronary stenting on 40 lesions in 34 patients with ESRD. We compared these lesions with 80 lesions from patients without renal disease who underwent coronary stenting in the STARS and WINS clinical trials, matched for treatment site, diabetes, lesion length, and reference vessel diameter. Quantitative coronary angiography was performed on all lesions and clinical outcomes were assessed at 9-month follow-up. Clinical and angiographic characteristics were well matched between the 2 groups and acute clinical success rates were similar. Despite comparable initial angiographic results over the 9-month follow-up period, repeat target lesion revascularization was twice as frequent in the ESRD group compared with the control group (35% vs 16%, p <0.05). After adjusting for differences in postprocedural minimum lumen diameter and other angiographic and clinical characteristics, ESRD remained the most important predictor of late target lesion revascularization (relative risk = 2.3, p = 0.04). In addition, overall 9-month mortality was higher for ESRD patients than for the control population (18% vs 2%, p <0.01). Thus, despite similar angiographic results, patients with ESRD are at higher risk for target lesion revascularization after coronary stenting than controls. Nonetheless, most patients with ESRD do not develop restenosis after stent placement, suggesting an important role for stenting in the management of this challenging population.

Abstract
Previous retrospective studies showed high periprocedure mortality rate and poor outcome after percutaneous transluminal coronary angioplasty (PTCA) or coronary artery bypass grafting (CABG) among renal dialysis patients. The purpose of this study was to compare mortality and clinical event rates in renal dialysis patients after PTCA or CABG. We identified 252 patients from the Emory Cardiovascular Database who were on dialysis and who received PTCA (122 patients) or CABG (130 patients) at Emory University Hospital and Crawford W. Long Hospital between March 1987 and December 1997. Baseline and angiographic characteristics, in-hospital, and 1-year outcome were compared between the 2 groups. Left main disease and 3-vessel coronary artery disease were significantly more common in the CABG group. There was a higher periprocedure and in-hospital mortality in the CABG group (6.9% vs 1.6%, p = 0.04). Patients in the PTCA group underwent repeat revascularization 11 times more frequently within 1 year (22% vs 2%). At 1 year, mortality was 23% in the PTCA group and 27% in the CABG group, with no statistical difference between the 2 groups. This nonrandomized comparison reveals that PTCA and CABG can be performed in selected renal dialysis patients with an acceptable in-hospital major complication rate; however, 1-year mortality remains high in dialysis patients after coronary revascularization. Therefore, attempts at improving outcome in dialysis patients should focus on the prevention and treatment of coronary artery disease before they require coronary revascularization.

Abstract
Cardiovascular disease is the leading cause of death in patients receiving dialysis. This is attributed in part to the shared risk factors of cardiovascular disease and end-stage renal disease. The risk factors for coronary artery disease include the classic cardiac risk factors of diabetes mellitus, hypertension, dyslipidemia, and smoking. Also in this population, hyperparathyroidism, hypoalbuminemia, hyperhomocysteinemia, elevated levels of apolipoprotein (a), and the type of dialysis membrane may play a role. Management begins with risk factor modification and medical therapy including aspirin, beta blockers, angiotensin converting enzyme (ACE) inhibitors, and lipid-lowering agents. Revascularization is often important, and coronary artery bypass grafting appears to be preferable to percutaneous transluminal coronary angioplasty. This is especially true for those with multivessel disease, impaired left ventricular function, severe symptoms, or ischemia. Congestive heart failure is another common problem in dialysis patients. The management includes correction of underlying abnormalities, optimal dialysis, and medical therapy. Data obtained from the general population indicate obvious benefits from ACE inhibitors and beta blockers, and these agents would be considered the therapies of choice. Erythropoetin is also an essential component of therapy, but the ideal hemoglobin concentration has yet to be determined. Peritoneal dialysis may be helpful in severe cases of heart failure. Pericarditis is seen in less than 10% of dialysis patients and is best diagnosed by clinical examination and echocardiography. Intensive dialysis is often the best initial therapy. Pericardiocentesis is reserved for the setting of pericardial tamponade, but a pericardial window is more definitive.

Abstract
BACKGROUND Patients with kidney failure have a heavy burden of coronary artery disease. The results of preventive, diagnostic, and therapeutic measures developed in nonuremic populations cannot automatically be extrapolated to this unique group of patients. METHODS AND RESULTS Articles were reviewed if they contained English language text or an abstract identified by MEDLINE search from 1980 to 1999, supplemented by manual review of bibliographies of published articles and abstract issues of national cardiology meetings, studies on diagnostic techniques, risk modification measures, pharmacologic agents, and coronary revascularization procedures in patients with uremia. Descriptive and quantitative data as appropriate were extracted. Lipid-lowering agents may be safely administered to uremic patients. Direct evidence of lipid lowering in this population is not available and is not likely to be forthcoming. Erythropoietin therapy is effective in reversing the cardiovascular perturbations of uremic anemia, but an approach of normalizing the hematocrit cannot be recommended. Glycoprotein IIb/IIIa inhibitors used in acute coronary syndromes require downward dose adjustment or are contraindicated. Thrombolytic agents are underutilized in the management of myocardial infarction. Noninvasive testing is less accurate than in nonuremic populations. Coronary revascularization offers relative clinical advantages over medical therapy similar to non-kidney failure populations, even though the results in uremic patients is significantly less favorable than for nonuremic patients. Stenting is the preferred revascularization approach, and conventional balloon percutaneous transluminal coronary angioplasty the least favorable. CONCLUSIONS Many but not all of the benefits of therapies developed in nonuremic patients extend to patients with kidney failure. Physicians should be familiar with the advantages and limitations of each of these modalities in this population.

Abstract
Cardiovascular disease (CVD) is the most common cause of death in patients with end-stage renal disease (ESRD). The optimal management strategy in this population is unknown. We studied 640 patients with ESRD and acute myocardial infarction during 1994 to 1995 as part of the Health Care Financing Administration's Cooperative Cardiovascular Project. The majority of patients were treated with medical therapy alone, 46 patients (7%) were treated with percutaneous transluminal coronary angioplasty (PTCA), and 29 patients (5%) underwent coronary artery bypass grafting (CABG). Patient characteristics and comorbid conditions were similar among the three groups. The overall 1-year mortality rate was 53%. Advanced age, low or high body mass index, history of peripheral vascular disease or stroke, the inability to walk independently, and several indicators of cardiac dysfunction were associated with an increased relative risk (RR) for death. Survival curves differed significantly by treatment modality, with 1-year survival rates of 45%, 54%, and 69% in the medical therapy alone, PTCA, and CABG groups, respectively (P = 0.03). After adjustment for confounding variables, the RR for death was less (but not significantly so) in the CABG group (RR, 0.6; 95% confidence interval, 0.3 to 1.1). There are no randomized clinical trial data to guide therapy of CVD in patients with ESRD. On the basis of these and other available data, CABG may be the optimal therapy for CVD in ESRD. In light of the exceptionally poor outcomes observed for patients treated with medical therapy alone, it may be premature to dismiss PTCA as a therapeutic option in this population.

Abstract
Renal transplantation is one of the preferred modes of replacement therapy in patients with end-stage renal disease. Cardiovascular disease remains the leading cause of morbidity and mortality in patients with end-stage renal disease and renal transplant recipients. The authors describe a patient with end-stage renal disease who developed unstable angina before renal transplantation. Emergent cardiac catheterization and percutaneous coronary intervention served as a bridge to his successful renal transplantation without complications.

Abstract
This study was conducted to investigate therapeutic methods for end-stage renal disease (ESRD) by retrospectively analyzing in-hospital outcome and long-term outcome in patients who underwent either percutaneous transluminal coronary angioplasty (PTCA) or coronary artery bypass grafting (CABG). Ninety-two patients underwent PTCA and 47 underwent CABG, and the initial success rates were 87% and 85%, respectively. As major in-hospital complications, in the PTCA group 1 died (1%), 2 required emergency CABG (2%), and 2 had Q-wave myocardial infarction (2%); in the CABG group, 7 died (15%) and 3 had Q-wave myocardial infarction (6%). As for the long-term outcome, although there were no differences in the incidence of death or the incidence of cardiac death between the 2 groups, the cumulative proportion of patients free of death, myocardial infarction, CABG and repeat PTCA was lower in the PTCA group, which was mainly due to a higher incidence of repeat PTCA in that group. The incidence of cardiac death was low for both groups among the patients attaining complete revascularization. Twenty-three percent of the patients required cross-over implementation of PTCA and CABG. In conclusion, it is necessary to aim for complete revascularization using both treatments for a better prognosis in patients with ESRD.

Abstract
BACKGROUND To analyze the characteristic problems of coronary artery bypass grafting in patients with chronic renal failure. METHODS Fifty-one consecutive dialysis patients who required isolated coronary bypass grafting over a 9-year period were studied retrospectively. RESULTS Nine patients (18%) had emergent operation, 4 of whom had intraaortic balloon counterpulsation instituted preoperatively. A mean of 3.3 +/- 1.0 bypasses per patient were grafted; 14 patients (27%) had bypass with two arterial grafts, 13 (25%) of which used left internal mammary artery and gastroepiploic artery and one of which used bilateral internal mammary artery grafts. A mean of 4.2 +/- 2.6 coronary artery segments were calcific according to American Heart Association classification. Eight patients (16%) required operative modifications to avoid manipulating calcific plaques on the ascending aorta. Four patients (7.8%) died, and 15 had nonlethal complications. The actuarial survival rates in 47 hospital survivors at 1, 3, and 5 years were overall 89%, 84%, and 71%, respectively, and estimates for cardiac deaths 93%, 93%, and 82%, respectively. Cardiac event-free rates after coronary artery bypass grafting were 83% and 65% for 3- and 5-year periods, respectively. CONCLUSIONS Calcification of coronary arteries and the ascending aorta is a serious problem in long-term dialysis patients. However using arterial grafts, preferentially, in situ, seems to provide a practical alternative to minimize manipulating the ascending aorta during coronary artery bypass grafting, with acceptable perioperative morbidity and mortality rates and long-term survival.

Abstract
OBJECTIVE Renal failure is known to increase the morbidity and mortality in patients undergoing cardiac surgery. The results of heart surgery in patients with non-dialysis-dependent, mild renal insufficiency are not clear. METHODS One hundred nineteen adult patients with chronic renal failure underwent cardiac surgery. Group I consisted of 93 patients who had creatinine levels between 1.6 and 2.5 mg/dL but who were not supported by dialysis. Group II consisted of 18 patients with creatinine levels higher than 2.5 mg/dL who were not supported by dialysis. Group III consisted of 8 patients with end-stage renal disease who were receiving hemodialysis. RESULTS The hospital mortality rates were 11.8%, 33.0%, and 12.5%, respectively. Morbidity was 21.5%, 44.4%, and 75.0%, respectively, in groups I, II, and III. Postoperative hemodialysis was needed in 2 (2.15%) patients from group I and 6 (33%) patients from group II. On multivariable logistic regression analysis, risk factors for mortality were preoperative creatinine level more than 2.5 mg/dL, angina class III-IV, emergency operation, excessive mediastinal hemorrhage, postoperative pulmonary insufficiency, low cardiac output, and rhythm disturbances. Risk factors for morbidity were preoperative creatinine level more than 2.5 mg/dL and postoperative dialysis. CONCLUSIONS Chronic renal failure increases the mortality and morbidity in patients undergoing cardiac surgery. Renal insufficiency with creatinine levels higher than 2.5 mg/dL increases the risk of postoperative dialysis and prolongs the length of hospital stay. Careful preoperative management and intraoperative techniques, such as avoiding low perfusion pressure and using low-dose dopamine, may be useful for a good operative outcome.

Abstract
The aim of this study was to obtain data on the outcomes of chronic hemodialysis patients who underwent percutaneous transluminal coronary angioplasty (PTCA). A retrospective chart analysis identified 31 such patients between August 1992 and October 1996. The mean follow-up period was 12.4 +/- 11.7 months. Angiographic success was achieved in 39 of 41 (95.1%) stenoses attempted. There were three in-hospital deaths. Clinical success was achieved in 28 of 31 patients (90%). Two of the 28 survivors were lost to follow-up. Recurrent angina developed within 6 months in 14 of 26 patients (53.8%). Eleven and 17 of the 26 patients (42.3% and 65.4%) died within 6 and 14 months, respectively, after the PTCA procedure. Ten of the 17 deaths (58.8%) were due to cardiovascular events. Our study suggests that PTCA is technically feasible with high angiographic success rate in chronic hemodialysis patients. In-hospital mortality rate and rate of recurrent angina are high. Long-term prognosis is poor.
