In-hospital outcomes of PCI in patients who have ESRD vs non-ESRD patients, a retrospective study involving a National Inpatient Sample (NIS) database. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2023; 56:43-49. [PMID: 37331888 DOI: 10.1016/j.carrev.2023.05.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 05/08/2023] [Accepted: 05/23/2023] [Indexed: 06/20/2023]
Abstract
BACKGROUND Cardiovascular disease is the leading cause of death for patients with end-stage renal disease (ESRD). ESRD is known to affect a large portion of the American population. Previous data for patients undergoing percutaneous coronary intervention (PCI) in the setting of ESRD for Acute Coronary Syndrome (ACS) and non-ACS etiologies have shown to have an increase in in-hospital mortality, and prolonged hospitalization among other complications. METHODS The national inpatient sample (NIS) was used to identify patients who underwent PCI between the years 2016-2019. Patients were then grouped into those with ESRD on renal replacement therapy (RRT). Logistic regression models were employed to assess the primary outcome of in-hospital mortality, while linear regression models were utilized to evaluate secondary outcomes, including hospitalization cost and length of stay. RESULTS A total of 21,366 unweighted observations were initially included, consisting of 50 % ESRD patients and 50 % randomly selected patients without ESRD who underwent PCI. These observations were weighted to represent a national estimate of 106,830 patients. The mean age of the study population was 65 years, and 63 % of the patients were male. The ESRD group had a greater representation of minority groups compared to the control group. The in-hospital mortality rate was significantly higher in the ESRD group compared to the control group, with an odds ratio of 1.803 (95 % CI: 1.502 to 2.164; p-value of 0.0002). Additionally, the ESRD group had significantly higher healthcare costs and longer length of stay, with a mean difference of $47,618 (95 % CI: $42,701 to $52,534, p-value <0.0001) and 2.933 days (95 % CI, 2.729 to 3.138 days, p-value <0.0001), respectively. CONCLUSION In-hospital mortality, cost, and length of stay for patients undergoing PCI were found to be significantly greater in the ESRD group.

Abstract
BACKGROUND Renal impairment is a known predictor of mortality in both the general population and in patients with cardiac disease. The aim of this study was to evaluate factors that determine mortality in patients with chronic kidney disease (CKD) who have undergone percutaneous coronary intervention (PCI). METHODS In this study we included 293 consecutive patients with CKD who underwent PCI between 1st January 2007 and 30th September 2012. The primary outcome that we studied was all-cause mortality in a follow-up period of 12-69 months (mean 38.8 ± 21.7). RESULTS Age (p < 0.001), PCI indication (p = 0.035), CKD stage (p < 0.001) and left ventricular ejection fraction (p < 0.001) were significantly related to mortality. CKD stage 5 [hazard ratio (HR) = 6.39, 95% CI: 1.51-27.12) and severely impaired left ventricular function (HR = 4.04, 95% CI: 2.15-7.59) were the strongest predictors of mortality. Other factors tested (gender, hypertension, diabetes, hyperlipidaemia, established peripheral vascular disease/stroke, coronary arteries intervened, number of vessels treated, number of stents implanted and length of lesion treated) did not show any correlation with mortality. CONCLUSIONS The mortality of patients with CKD undergoing PCI increases with age, worsening CKD stage and deteriorating left ventricular systolic function, and it is also higher in patients with acute coronary syndromes compared to those with stable coronary artery disease.

Abstract
Background: Multivessel coronary artery disease carries significant mortality risk. Comprehensive data on inhospital outcomes following multivessel percutaneous coronary intervention (MVPCI) are sparse. Methods: We queried the Healthcare Cost and Utilization Project’s nationwide inpatient sample (NIS) between 2006 and 2011 using different International Classification of Diseases, 9th Revision, Clinical Modification procedure codes. The primary outcome was inhospital all-cause mortality, and the secondary outcome was a composite of inhospital mortality and periprocedural complications. Results: The overall mortality was low at 0.73% following MVPCI. Multivariate analysis revealed that (odds ratio, 95% confidence interval, P value) age (1.63, 1.48-1.79; <.001), female sex (1.19, 1.00-1.42; P = .05), acute myocardial infarction (AMI; 2.97, 2.35-3.74; <.001), shock (17.24, 13.61-21.85; <.001), a higher burden of comorbidities (2.09, 1.32-3.29; .002), and emergent/urgent procedure status (1.67, 1.30-2.16; <.001) are important predictors of primary and secondary outcomes. MVPCI was associated with higher mortality, length of stay (LOS), and cost of care as compared to single vessel single stent PCI. Conclusion: MVPCI is associated with higher inhospital mortality, LOS, and hospitalization costs compared to single vessel, single stent PCI. Higher volume hospitals had lower overall postprocedural mortality rate along with shorter LOS and lower hospitalization costs following MVPCI.

Abstract
Background The association of chronic renal insufficiency with outcomes after percutaneous coronary intervention (PCI) in the current era of drug-eluting stents and modern antithrombotic therapy has not been well characterized. Methods and Results We queried the 2007–2011 Nationwide Inpatient Sample databases to identify all patients aged ≥18 years who underwent PCI. Multivariable logistic regression was used to compare in-hospital outcomes among patients with chronic kidney disease (CKD), patients with end-stage renal disease (ESRD), and those without CKD or ESRD. Of 3 187 404 patients who underwent PCI, 89% had no CKD/ESRD; 8.6% had CKD; and 2.4% had ESRD. Compared to patients with no CKD/ESRD, patients with CKD and patients with ESRD had higher in-hospital mortality (1.4% versus 2.7% versus 4.4%, respectively; adjusted odds ratio for CKD 1.15, 95% CI 1.12 to 1.19, P<0.001; adjusted odds ratio for ESRD 2.29, 95% CI 2.19 to 2.40, P<0.001), higher incidence of postprocedure hemorrhage (3.5% versus 5.4% versus 6.0%, respectively; adjusted odds ratio for CKD 1.21, 95% CI 1.18 to 1.23, P<0.001; adjusted odds ratio for ESRD 1.27, 95% CI 1.23 to 1.32, P<0.001), longer average length of stay (2.9 days versus 5.0 days versus 6.4 days, respectively; P<0.001), and higher average total hospital charges ($60 526 versus $77 324 versus $97 102, respectively; P<0.001). Similar results were seen in subgroups of patients undergoing PCI for acute coronary syndrome or stable ischemic heart disease. Conclusions In patients undergoing PCI, chronic renal insufficiency is associated with higher in-hospital mortality, higher postprocedure hemorrhage, longer average length of stay, and higher average hospital charges.

Abstract
Despite the improvements in diagnostic tools and medical applications, cardiovascular diseases (CVD), especially coronary artery disease (CAD), remain the most common cause of morbidity and mortality in patients with chronic kidney disease (CKD). The main factors for the heightened risk in this population, beside advanced age and a high proportion of diabetes and hypertension, are malnutrition, chronic inflammation, accelerated atherosclerosis, endothelial dysfunction, coronary artery calcification, left ventricular structural and functional abnormalities, and bone mineral disorders. Chronic kidney disease is now recognized as an independent risk factor for CAD. In community-based studies, decreased glomerular filtration rate (GFR) and proteinuria were both found to be independently associated with CAD. This paper will discuss classical and recent epidemiologic, pathophysiologic, and clinical aspects of CAD in CKD patients.

Abstract
BACKGROUND Chronic kidney disease (CKD) is associated with worse outcomes among patients with acute coronary syndrome (ACS). Less is known about the impact of CKD on longitudinal outcomes among clopidogrel treated patients following ACS. METHODS Using a retrospective cohort design, we identified patients hospitalized with ACS between 10/1/2005 and 1/10/10 at Department of Veterans Affairs (VA) facilities and who were discharged on clopidogrel. Using outpatient serum creatinine values, estimated glomerular filtration rate [eGFR (1.73 ml/min/m2)] was calculated using the CKD-EPI equation. The association between eGFR and mortality, hospitalization for acute myocardial infarction (AMI), and major bleeding were examined using Cox proportional hazards models. RESULTS Among 7413 patients hospitalized with ACS and discharged taking clopidogrel, 34.5% had eGFR 30-60 and 11.6% had eGFR < 30. During 1-year follow-up after hospital discharge, 10% of the cohort died, 18% were hospitalized for AMI, and 4% had a major bleeding event. Compared to those with eGFR > =60, individuals with eGFR 30-60 (HR 1.45; 95% CI: 1.18-1.76) and < 30 (HR 2.48; 95% CI: 1.97-3.13) had a significantly higher risk of death. A progressive increased risk of AMI hospitalization was associated with declining eGFR: HR 1.20; 95% CI: 1.04-1.37 for eGFR 30-60 and HR 1.47; 95% CI: 1.22-1.78 for eGFR < 30. eGFR < 30 was independently associated with over a 2-fold increased risk in major bleeding (HR 2.09; 95% CI: 1.40-3.12) compared with eGFR > = 60. CONCLUSION Lower levels of kidney function were associated with higher rates of death, AMI hospitalization, and major bleeding among patients taking clopidogrel after hospitalization for ACS.

Abstract
BACKGROUND Stent thrombosis (ST), a postinterventional complication with a mortality rate of 50%, has an incidence that rises precipitously in patients at risk. Chronic renal failure and end-stage renal disease have emerged as particularly strong ST risk factors, yet the mechanism remains elusive. Tissue factor (TF) is a crucial mediator of injury-related thrombosis and has been implicated for ST. We posit that uremia modulates TF in the local vessel wall to induce postinterventional thrombosis in patients with end-stage renal disease. METHODS AND RESULTS As a model of the de-endothelialized, postinterventional state, we exposed primary human vascular smooth muscle cells (vSMCs) pretreated with uremic serum (obtained from ESRD patients on hemodialysis) to coronary-like blood flow. vSMC TF expression, activity, stability, and posttranslational modification were examined after vSMCs were treated with uremic serum or solutes. We found significantly greater clot formation after uremic serum exposure, which was substantially reduced with the prior treatment with anti-TF neutralizing antibody. Uremic sera induced 2- to 3-fold higher TF expression and activity in vSMCs independent of diabetes mellitus. Relevant concentrations of isolated uremic solutes such as indole-3-acetic acid (3.5 μg/mL), indoxyl sulfate (25 μg/mL), and uric acid (80 μg/mL) recapitulated these effects in cell culture and the flow loop model. We show further that TF undergoes ubiquitination at baseline and that uremic serum, indole-3-acetic acid, and indoxyl sulfate significantly prolong TF half-life by inhibiting its ubiquitination. CONCLUSIONS The uremic milieu is profoundly thrombogenic and upregulates vSMC TF levels by increasing TF stability and decreasing its ubiquitination. Together, these data demonstrate for the first time that the posttranslational regulation of TF in uremia may have a causative role in the increased ST risk observed in uremic patients. These data suggest that interventions that reduce vSMC TF may help to prevent ST and that uremic solutes should be considered as novel risk factors for ST in patients with chronic renal failure.

Abstract
Renal dysfunction is an independent predictor of cardiovascular events and a negative prognostic indicator after myocardial infarction (MI). Randomized data comparing percutaneous coronary intervention to medical therapy in patients with MI with renal insufficiency are needed. The Occluded Artery Trial (OAT) compared optimal medical therapy alone to percutaneous coronary intervention with optimal medical therapy in 2,201 high-risk patients with occluded infarct arteries >24 hours after MI with serum creatinine levels ≤2.5 mg/dl. The primary end point was a composite of death, MI, and class IV heart failure (HF). Analyses were carried out using estimated glomerular filtration rate (eGFR) as a continuous variable and by eGFR categories. Long-term follow-up data (maximum 9 years) were used for this analysis. Lower eGFR was associated with development of the primary outcome (6-year life-table rates of 16.9% for eGFR >90 ml/min/1.73 m(2), 19.2% for eGFR 60 to 89 ml/min/1.73 m(2), and 34.9% for eGFR <60 ml/min/1.73 m(2); p <0.0001), death, and class IV HF, with no difference in rates of reinfarction. On multivariate analysis, eGFR was an independent predictor of death and HF. There was no effect of treatment assignment on the primary end point regardless of eGFR, and there was no significant interaction between eGFR and treatment assignment on any outcome. In conclusion, lower eGFR at enrollment was independently associated with death and HF in OAT participants. Despite this increased risk, the lack of benefit from percutaneous coronary intervention in the overall trial was also seen in patients with renal dysfunction and persistent occlusion of the infarct artery in the subacute phase after MI.

Abstract
BACKGROUND Monomicrobial necrotizing fasciitis is rapidly progressive and life-threatening. This study was undertaken to ascertain whether the clinical presentation and outcome for patients with this disease differ for those infected with a gram-positive as compared to gram-negative pathogen. METHODS Forty-six patients with monomicrobial necrotizing fasciitis were examined retrospectively from November 2002 to January 2008. All patients received adequate broad-spectrum antibiotic therapy, aggressive resuscitation, prompt radical debridement and adjuvant hyperbaric oxygen therapy. Eleven patients were infected with a gram-positive pathogen (Group 1) and 35 patients with a gram-negative pathogen (Group 2). RESULTS Group 2 was characterized by a higher incidence of hemorrhagic bullae and septic shock, higher APACHE II scores at 24 h post-admission, a higher rate of thrombocytopenia, and a higher prevalence of chronic liver dysfunction. Gouty arthritis was more prevalent in Group 1. For non-survivors, the incidences of chronic liver dysfunction, chronic renal failure and thrombocytopenia were higher in comparison with those for survivors. Lower level of serum albumin was also demonstrated in the non-survivors as compared to those in survivors. CONCLUSIONS Pre-existing chronic liver dysfunction, chronic renal failure, thrombocytopenia and hypoalbuminemia, and post-operative dependence on mechanical ventilation represent poor prognostic factors in monomicrobial necrotizing fasciitis. Patients with gram-negative monobacterial necrotizing fasciitis present with more fulminant sepsis.

Chronic kidney disease (CKD) is associated with a high burden of coronary artery disease, myocardial infarction and cardiovascular death. Detection and treatment of coronary artery disease in CKD patients has been hampered by the limitations of screening tests, the lack of direct evidence for therapeutic interventions in this specific population, and concerns about therapy-related adverse effects. However, these patients potentially have much to gain from conventional strategies used in the general population. This review summarises the current evidence regarding the treatment of coronary artery disease in patients with CKD, with the focus on coronary revascularisation by percutaneous coronary intervention or coronary artery bypass grafting.

Abstract
Introduction: We aim to examine the risk predictors of contrast-induced nephropathy (CIN) in patients with normal baseline serum creatinine (Cr). CIN is an important complication post percutaneous coronary intervention (PCI). Previous studies examined CIN predictors in patients with chronic renal impairment. No large studies investigated patients with normal renal function which constitute the majority undergoing PCI. We aim to identify risk predictors in this cohort and examine the clinical outcomes. Materials and Methods: A total of 3036 patients with normal baseline Cr (<1.5 mg/dL) who did not receive prophylaxis while undergoing PCI were enrolled. We examined the occurrence of CIN and the mortality outcome at 1 and 6 months. Results: CIN occurred in 7.3% of patients. The median age was 59.5 years (range, 26 to 86), 78.7% men, 34.6% diabetics. Risk predictors for CIN include age [odds ratio (OR), 6.4; 95% CI, 1.01-13.3; P = 0.042], female gender (OR, 2.0; 95% CI, 1.5-2.7; P = 0.001), abnormal left ventricular ejection fraction (LVEF) <50%(OR,1.02; 95% CI, 1.01-1.04; P = 0.01), anaemia with haemoglobin <11 mg/dL (OR, 1.5; 95% CI, 1.01-2.4; P = 0.044) and systolic hypotension with blood pressure <100 mmHg (OR, 1.5; 95% CI, 1.01-2.2; P = 0.004). Diabetics on insulin therapy were at the highest risk compared with diabetics on oral hypoglycaemics and diet control (18.9% vs 6.8% vs 3.6%; P = 0.001). Patients who developed CIN had higher mortality at 1 month (14.5% vs 1.1%; P <0.001) and 6 months (17.8% vs 2.2%; P <0.001). Conclusions: Subgroups of patients with normal baseline Cr undergoing PCI are at risk of developing CIN with resultant higher mortality. Age, female gender, insulin dependent diabetes mellitus, presence of hypotension, anaemia and low LVEF are predictors of CIN. Prophylaxis may be considered in these patients.

Abstract
Background—
An observational study determining the long-term impact of chronic kidney disease (CKD) on patients undergoing percutaneous coronary intervention at a tertiary cardiac referral center. CKD is associated with poor in-hospital outcomes after percutaneous coronary intervention, but its effect beyond 1 year, particularly in the drug-eluting stent (DES) era, has not been reported.
Methods and Results—
Baseline creatinine was available for 11 953 patients entered into a prospective registry (April 2000 to September 2007). Patients were stratified: those with or without at least moderate CKD (creatinine clearance, <60 mL/min). Follow-up data were obtained through linkage to a provincial registry. Kaplan–Meier analysis was performed. Cox multiple-regression analysis identified independent predictors of late mortality and major adverse cardiac events (MACE) and examined the association between DES use and late outcomes in the presence or absence of CKD. CKD was present in 3070 patients (25.7%). In-hospital mortality and MACE were significantly increased in CKD (3.34% versus 0.44%,
P
<0.001 and 5.73% versus 2.2%,
P
<0.001). Survival and MACE-free survival at 7 years were reduced (64.5�1.4% versus 89.4�0.5%,
P
<0.001; 44.0�1.4% versus 63.4�0.8%,
P
<0.001). CKD was an independent predictor of late mortality and MACE (hazard ratio [HR]: 2.18, CI: 1.90 to 2.49,
P
<0.0001; HR: 1.37, CI: 1.25 to 1.49,
P
<0.0001). DES use was associated with a significant reduction in both (HR: 0.71, CI: 0.60 to 0.83,
P
<0.0001; HR: 0.70, CI: 0.63 to 0.78,
P
<0.0001). In patients with CKD, DES use was associated with reduced revascularization (HR: 0.68, CI: 0.53 to 0.88,
P
=0.004) and reduced MACE (HR: 0.81, CI: 0.69 to 0.95,
P
=0.011) but not reduced mortality (HR: 0.85, CI: 0.69 to 1.05,
P
=0.1).
Conclusion—
In a large registry of “all comers” for percutaneous coronary intervention, CKD was an independent predictor of adverse late outcomes. DES use may be associated with improved long-term outcomes in this high-risk cohort, but further prospective studies are required.

Abstract
Patients with chronic renal insufficiency (RI) have higher in-hospital mortality and major adverse cardiac event (MACE) rates after percutaneous coronary intervention (PCI). The mechanisms of this adverse course are not well understood. It was hypothesized that this worse outcome may be caused by inadequate PCI results secondary to more complex coronary anatomy in patients with RI. Baseline, procedural, and outcome variables of all PCI cases at the University Health Network are entered prospectively in the PCI Registry. All PCI cases between April 1, 2000, and October 31, 2005, excluding patients in shock, who had preprocedural creatinine clearance (CrCl) measured were included in this study (n = 10,821 of 11,023 patients). Moderate RI (CrCl <60 ml/min) was evaluated as an independent predictor of procedural outcomes, death, and MACE (defined as death, myocardial infarction, abrupt closure, or coronary artery bypass grafting). Moderate RI (CrCl <60 ml/min) independently predicted the procedural outcomes of worse residual stenosis >20% (p = 0.03), number of undeliverable stents (p = 0.003), and smallest stent diameter (p <0.001). Worst residual stenosis >20% and any undeliverable stent were significantly associated with in-hospital MACEs (odds ratio [OR] 3.97, 95% confidence interval [CI] 3.0 to 5.3, p <0.001 and OR 1.89, 95% CI 1.2 to 2.9, p = 0.002) and mortality (OR 3.82, 95% CI 2.2 to 6.7, p <0.001 and OR 3.0, 95% CI 1.6 to 5.9, p = 0.002). These risks were independent of all other measured variables. In conclusion, moderate to severe RI was a strong predictor of worse procedural results during PCI, which, in turn, were independent predictors of in-hospital MACE and mortality and independent contributors to the higher risk of in-hospital adverse events observed after PCI in patients with RI.

Abstract
OBJECTIVES To assess the effect of renal impairment (RI) and diabetes (DM) on outcomes in non-ST-segment elevation acute coronary syndromes (NSTE-ACS). METHODS Data were pooled from 13,126 patients in five NSTE-ACS TIMI trials (TIMI 11A and B, TIMI 12, OPUS-TIMI 16, and TACTICS-TIMI 18). Patients were divided based on DM status and RI (none, mild, or moderate if the glomerular filtration rate (GFR, ml/min/1.73 m(2)) was > or = 90, 60-89 and 30-59 respectively). RESULTS Patients with DM and moderate RI (n=609) were older and had more prior MI (p<0.01 for all) than other subgroups. Compared with no RI/DM (n=3,832), the 12-month adjusted risks of death, MI, and death/MI increased with advancing RI and were highest with DM and moderate RI (H.R. 1.7, (1.2-2.4), p=0.002; H.R. 2.0 (1.5-2.6), p<0.001; and H.R. 1.7 (1.3-2.2), p<0.001 respectively). These events were also increased with DM and mild RI (H.R. 1.4, (1.0-1.9), p=0.06, H.R. 1.4 (1.1-1.8), p=0.006 and H.R. 1.3 (1.1-1.7), p=0.007 respectively) but not with 1) mild or moderate RI without DM or 2) DM without RI. The interaction terms for RI and DM in their association with MI and death/MI were significant. CONCLUSIONS In the absence of DM, RI and in the absence of RI, DM did not increase the risk of MI or death/MI. However, the combination of RI and DM was associated with a particularly high risk of MI and death/MI suggesting that attention to preserving renal function may be of particular benefit for reducing cardiovascular risk in diabetic patients.

Abstract
The treatment of patients with ST elevation acute myocardial infarction (STEAMI) and renal failure (RF) represents one of the most challenging problems with which the cardiologists are faced. It has been well established that patients suffering of acute coronary syndromes with concomitant renal failure have a worse outcome as compared with those with normal renal function. Leading causes for this adverse outcome are excess comorbidities in patients with renal failure, lesser use of beneficial therapies and the unique pathophysiology involved in the diseased kidney. The entire setup of abnormalities in coagulation, fibrinolysis, platelet aggregation, lipids metabolism, endothelial function and a high inflammatory state, is responsible for the increased risk of restenosis, recurrent myocardial infarction, congestive heart failure, and cardiovascular death among cardiac patients with impaired renal function. The results provided by the very small number of studies in literature evaluating methods of reperfusion in patients with ST elevation myocardial infarction and impaired renal function are very sparse, and a prospective trial to solve this therapeutic dilemma that clinicians are faced with, at the bedside of patients with STEAMI and RF is needed.

Abstract
OBJECTIVES To determine the impact of the level of kidney function on the extended (>5 years) long-term clinical course of patients undergoing percutaneous coronary intervention (PCI). BACKGROUND Chronic kidney disease (CKD) has been significantly associated with an increased in-hospital and 1-year mortality following PCI. METHODS In this single-centre retrospective study, glomerular filtration rate (GFR) at baseline was estimated in 371 patients not on dialysis, who underwent successful PCI between mid-1995 and mid-1999. Baseline demographic and angiographic characteristics, and long-term major adverse cardiac events and symptoms were compared for patients with GFR > or =60 ml/min/1.73 m(2) (normal or mildly impaired renal function) and GFR > or = 60 ml/ min/1.73 m(2) (CKD). The independent effect of GFR, modelled both as a categorical and a continuous variable, on long-term clinical outcomes was also investigated using multivariate Cox regression analysis. RESULTS Nine-year all-cause and cardiac mortality rates were significantly higher in the CKD group (45.9% vs. 10.6%, P < 0.0001 and 35.4% vs. 7.1%, P < 0.0001 respectively), while there was no difference in the repeat revascularization (P = 0.27) and nonfatal Q-wave myocardial infarction (P = 0.74) rates. Multivariate analysis demonstrated an independent impact of the level of GFR on long-term mortality; adjusted 9-year all-cause and cardiac mortality increased by approximately 16% and 11%, respectively for a decrease of GFR from 120 to 60 ml/min/1.73 m(2) and by approximately 14% and 9%, respectively for a decrease of GFR from 60 to 30 ml/min/1.73 m(2). CONCLUSIONS The level of renal function is a strong determinant of long-term all-cause and cardiac mortality after successful PCI.

Abstract
Data from patients who had ST-elevation acute myocardial infarction and renal failure and were enrolled in the 2002 Acute Coronary Syndrome Israeli Survey (ACSIS) were studied to determine the effect of different myocardial reperfusion modalities on short- and long-term outcomes. Thirty-day crude mortalities were 8.3% in the thrombolysis group, 40.0% in the primary percutaneous coronary intervention group, and 29.7% in the no-reperfusion group (p = 0.03). Crude and adjusted mortality odds ratios that were observed at 7, 30, and 365 days, with the thrombolysis group as the reference, were 3.1 to 8.1 in the percutaneous coronary intervention group and 1.5 to 4.6 in the no-reperfusion group. Our results suggest that thrombolysis may represent the preferred modality of reperfusion therapy in patients with renal failure and ST-elevation acute myocardial infarction. A large randomized prospective study is needed to confirm these results.

Abstract
OBJECTIVE Prophylactic hemofiltration has been reported, in one study, to reduce renal complications and death but necessitates additional up-front health care resource deployment in a critical care setting. We sought to explore the potential scope and cost-effectiveness of this strategy. DESIGN Economic evaluation using decision analysis. SETTING Tertiary or quaternary care hospital. PATIENTS Subjects undergoing angiography at risk for developing contrast nephropathy. INTERVENTION Prophylactic hemofiltration was compared with intravenous saline. Secondary models incorporated sodium bicarbonate and N-acetylcysteine as comparators. MEASUREMENT AND MAIN RESULTS The cost per quality-adjusted life year (QALY) gained with hemofiltration compared with intravenous saline in high-risk subjects (mean serum creatinine, 265 micromol/L) was 3,900 US dollars. This finding was sensitive to variations in several important variables. For instance, the cost-effectiveness ratio became less attractive (i.e., >50,000 US dollars/QALY) when hemofiltration was used in lower-risk subjects (serum creatinine, <265 micromol/L). The cost-effectiveness remained <50,000 US dollars/QALY provided that the relative risk of hemofiltration compared with saline alone was below 0.65 (reported relative risk, 0.10). Although based on indirect comparison of clinical efficacy, when N-acetylcysteine or sodium bicarbonate was used as the comparator, the cost per QALY gained for hemofiltration became markedly less attractive (50,100 US dollars and >1,000,000 US dollars), although the relative effectiveness of these three strategies strongly influenced the results. CONCLUSIONS Use of prophylactic hemofiltration in patients at high risk for contrast nephropathy may be potentially cost-effective only if certain conditions are satisfied, and its attractiveness is materially diminished when compared to other strategies. As this invasive therapy would entail certain immediate resource outlay, before considering its implementation it is crucial to confirm the clinical effectiveness and health care resource consequences of hemofiltration relative to current standards of care in future studies.

Abstract
Patients with chronic renal insufficiency (CRI) have higher rates of target vessel revascularization and mortality. The efficacy of sirolimus-eluting stents (SESs) to improve the clinical outcomes of these patients is unknown. We investigated the effect of SESs versus bare metal stents (BMSs) on outcomes of patients with CRI. Among the first 1,522 patients treated with SESs, 76 were identified with CRI and 1,446 without CRI. In-hospital and 1- and 6-month clinical outcomes were compared with 153 patients with CRI who were treated with BMSs. Patients with CRI were older, hypertensive, and diabetic and had more previous myocardial infarctions, revascularizations, and decreased left ventricular function (p <0.001). These patients had more saphenous vein graft lesions, were treated with more debulking devices (p <0.003), and had higher rates of in-hospital complications and mortality (p <0.001) compared with those without CRI. Among patients with CRI, treatment with SESs did not affect clinical outcomes at 1 month and was associated with lower incidences of target vessel revascularization (7.1% vs 22.1%, p = 0.02) at 6 months but did not affect other events, including mortality (16.7% vs 14.7% p = 0.89), compared with BMSs. However, treatment with SESs in patients without CRI was associated with significantly lower rates of major adverse cardiac events at 6 months (p <0.001). In conclusion, percutaneous coronary intervention with SESs in patients with CRI is associated with low rates of repeat revascularization compared with BMSs but has no effect on mortality at 6 months.

Abstract
BACKGROUND Moderate to severe impairment of renal function has emerged as a potent risk factor for adverse short- and long-term outcomes among patients presenting with cardiac disease. AIMS We sought to define the clinical, late mortality and economic burden of this risk factor among patients presenting to cardiac intensive care. METHODS A clinical audit of patients presenting to cardiac intensive care was undertaken between July 2002 and June 2003. All patients presenting with cardiac diagnoses were included in the study. Baseline creatinine levels were assessed in all patients. Late mortality was assessed by the interrogation of the National Death Register. Renal impairment was defined as estimated glomerular filtration rate <60 mL/min per 1.73 m2, as calculated by the Modified Diet in Renal Disease formula. In-hospital and late outcomes were compared by Cox proportional hazards modelling, adjusting for known confounders. A matched analysis and attributable risk calculation were undertaken to assess the proportion of late mortality accounted for by impairment of renal function and other known negative prognostic factors. The in-hospital total cost associated with renal impairment was assessed by linear regression. RESULTS Glomerular filtration rate <60 mL/min per 1.73 m2 was evident in 33.0% of this population. Among these patients, in-hospital and late mortality were substantially increased: risk ratio 13.2; 95% CI 3.0-58.1; P < 0.001 and hazard ratio 6.2; 95% CI 3.6-10.7; P < 0.001, respectively. In matched analysis, renal impairment to this level was associated with 42.1% of all the late deaths observed. Paradoxically, patients with renal impairment were more conservatively managed, but their hospitalizations were associated with an excess adjusted in-hospital cost of $A1676. CONCLUSION Impaired renal function is associated with a striking clinical and economic burden among patients presenting to cardiac intensive care. As a marker for future risk, renal function accounts for a substantial proportion of the burden of late mortality. The burden of risk suggests a greater potential opportunity for improvement of outcomes through optimisation of therapeutic strategies.

Abstract
BACKGROUND End-stage renal failure is associated with poor outcomes, including increased mortality, after percutaneous coronary intervention (PCI). The effect of milder degrees of renal insufficiency (RI) is less clear, especially with routine stenting and glycoprotein IIb/IIIa inhibitor therapy, which may be of particular benefit in patients with RI. METHODS Clinical, angiographic, procedural, and outcome variables of 7769 consecutive patients who underwent PCI between April 2000 and July 2004 were entered into a prospective database. Inhospital mortality and morbidity were calculated according to baseline creatinine clearance. Simple and multiple logistic regression analyses were performed to determine independent predictors of mortality. RESULTS Baseline creatinine clearance was available in 6840 patients. It was normal (> 80 mL/min) in 3474; 1670 had mild RI (61-80 mL/min), 1111 moderate RI (41-60 mL/min), and 585 severe RI (< or = 40 mL/min). Major adverse cardiac events (MACE) (death/myocardial infarction/revascularization) increased substantially with worsening renal function (2.4% vs 3.0% vs 4.8% vs 9.7%, P < .0001), as did mortality (0.3% vs 0.7% vs 1.5% vs 6.0%, P < .0001). Multiple logistic regression analysis identified moderate RI and severe RI as independent predictors of mortality (odds ratio [OR] 3.9, P < .001; OR 12.7, P < .0001, respectively) and morbidity (MACE) (OR 1.5, P < .05; OR 2.5, P < .0001, respectively). Mild RI trended to increase the risk of mortality but did not reach statistical significance as an independent predictor of inhospital death on multiple regression analysis (OR 2.1, P = .1) and did not increase the risk of MACE (OR 1.1, P = .6). CONCLUSIONS Despite routine stenting and glycoprotein IIb/IIIa inhibitor therapy, RI remains an independent predictor of increased morbidity, and particularly mortality, after PCI. However, the adverse effect of truly mild RI on outcome is limited.

Impact of moderate renal insufficiency on restenosis and adverse clinical events after paclitaxel-eluting and bare metal stent implantation: results from the TAXUS-IV Trial. Am Heart J 2005; 150:1163-70. [PMID: 16338253 DOI: 10.1016/j.ahj.2005.01.032] [Citation(s) in RCA: 70] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2004] [Accepted: 01/19/2005] [Indexed: 11/18/2022]
Abstract
BACKGROUND Mortality and restenosis may be increased in patients with mild to moderate renal insufficiency (RI) after coronary stent implantation. Whether drug-eluting stents safely reduce restenosis and enhance event-free survival in these patients is unknown. We sought to evaluate the impact of baseline RI on clinical and angiographic outcomes in patients undergoing elective percutaneous coronary intervention using either bare metal or paclitaxel-eluting stents. METHODS In the TAXUS-IV trial, 1314 patients were randomized to either the polymer-based paclitaxel-eluting TAXUS stent or an identical-appearing bare metal stent. Outcomes were stratified on the basis of the presence of RI, defined as a baseline creatinine clearance < 60 cm3/min calculated by the Cockcroft-Gault formula. RESULTS Baseline RI was present in 223 (17.2%) patients, in whom the mean creatinine clearance was 49.6 +/- 8.5 cm3/min. Compared with bare metal stents, treatment with the TAXUS stent resulted in lower rates of 9-month angiographic restenosis rates in both patients with (2.1% vs 20.5%, P = .009) and without (9.2% vs 27.8%, P < .0001) baseline RI. Similarly, 1-year target lesion revascularization rates were reduced with the TAXUS stent in patients with (3.3% vs 12.2%, P = .01) and without (4.7% vs 15.8%, P < .0001) baseline RI. The occurrence of death, myocardial infarction, and stent thrombosis at 1 year were similar in both randomization groups, independent of renal function. CONCLUSIONS The polymer-based paclitaxel-eluting TAXUS stent safely reduces clinical and angiographic restenosis in patients with preserved as well as moderate impairment of baseline renal function.

Impact of renal function on coronary plaque morphology and morphometry in patients with chronic renal insufficiency as determined by intravascular ultrasound volumetric analysis. Am J Cardiol 2005; 96:892-6. [PMID: 16188511 DOI: 10.1016/j.amjcard.2005.05.042] [Citation(s) in RCA: 32] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2005] [Revised: 05/21/2005] [Accepted: 05/21/2005] [Indexed: 10/25/2022]
Abstract
The aim of the present study was to use intravascular ultrasonography (IVUS) to assess plaque morphology and morphometry in patients with varying degrees of chronic renal insufficiency, including end-stage renal disease (ESRD) on dialysis replacement. Cardiovascular disease is the main cause of death for patients with chronic renal insufficiency, particularly in patients with ESRD. The impact of several degrees of renal insufficiency (including ESRD) on coronary plaque characteristics has not been determined. A total of 142 patients who underwent IVUS imaging of a de novo native coronary artery stenosis before percutaneous intervention were matched for age, gender, and diabetes and were grouped according to calculated creatinine clearance (CrCl): CrCl >70 ml/min (n = 39); CrCl 50 to 69 ml/min (n = 41); CrCl <50 ml/min, (n = 37), and ESRD (n = 25). Standard clinical, angiographic, and IVUS parameters were measured. The ESRD group had more African-American (p = 0.002) and hypertensive (p = 0.002) patients. No significant difference was found in any of the IVUS measurements among patients with CrCl >70, 50 to 69, and <50 ml/min: reference and lesion site arterial, lumen, and plaque areas and volumes, and arterial calcium (p = NS for all comparisons). Conversely, patients with ESRD had larger reference segment arterial and lumen areas and volumes; larger lesion site arterial, lumen, and plaque areas; and larger arcs of calcium (p <0.05 for all post hoc comparisons between patients with ESRD and patients with CrCl >70, 50 to 69, and <50 ml/min). Thus, chronic renal insufficiency in the absence of dialysis is not associated with increased reference segment or lesion site plaque burden and calcium. However, the transition to the need for dialysis is associated with progressive calcific atherosclerosis (larger lesion plaque area and calcium).

Abstract
BACKGROUND The short- and long-term effects of prophylactic hemodialysis (HD) immediately after cardiovascular catheterizations on renal function in patients with severe baseline renal insufficiency remain unknown though previous studies reported non-beneficial very-short-term effect in less severe patients. METHODS AND RESULTS Patients who had pre-procedural serum creatinine (Scr) between 2.5 and 5.5 mg/dl were retrospectively studied. Twenty of them (14 M/6 F, aged 69 +/- 2 years) had received prophylactic HD after radiocontrast exposure and constituted the HD group. Another 20 patients were case-matched to the baseline demographics of the HD group and served as the non-HD group. The baseline Scr were 3.9 +/- 0.2 and 3.5 +/-0.2 mg/dl, respectively (p = NS). Although the Scr at 3 months was significantly higher in the HD group (4.3 +/- 0.3 vs. 3.4 +/- 0.2 mg/dl, p = 0.02), the absolute and percentage increments from baseline to 3 months (0.4 +/- 0.2 vs. 0.0 +/- 0.2 mg/dl, p = NS, and 11 +/- 5% vs. 1 +/- 7%, p = NS, respectively) and 6 months (0.6 +/- 0.3 vs. 0.4 +/- 0.4 mg/dl, p = NS, and 18 +/- 8% vs. 8 +/- 10%, p = NS, respectively) were not statistically different. Patients who developed end-stage renal disease requiring permanent HD at 1 year were also similar in both groups (four vs. three, respectively, p = NS). CONCLUSIONS Our study confirmed that prophylactic HD immediately after contrast media administration in catheterizations failed to affect the short- and long-term renal and clinical outcomes even in patients with severe baseline renal insufficiency.

Abstract
OBJECTIVES The aim of this research was to assess the incidence, clinical predictors, and outcome of contrast-induced nephropathy (CIN) after primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI). BACKGROUND Contrast-induced nephropathy is associated with significant morbidity and mortality after PCI. Patients undergoing primary PCI may be at higher risk of CIN because of hemodynamic instability and unfeasibility of adequate prophylaxis. METHODS In 208 consecutive AMI patients undergoing primary PCI, we measured serum creatinine concentration (Cr) at baseline and each day for the following three days. Contrast-induced nephropathy was defined as a rise in Cr >0.5 mg/dl. RESULTS Overall, CIN occurred in 40 (19%) patients. Of the 160 patients with baseline Cr clearance >/=60 ml/min, only 21 (13%) developed CIN, whereas it occurred in 19 (40%) of those with Cr clearance <60 ml/min (p < 0.0001). In multivariate analysis, age >75 years (odds ratio [OR] 5.28, 95% confidence interval [CI] 1.98 to 14.05; p = 0.0009), anterior infarction (OR 2.17, 95% CI 0.88 to 5.34; p = 0.09), time-to-reperfusion >6 h (OR 2.51, 95% CI 1.01 to 6.16; p = 0.04), contrast agent volume >300 ml (OR 2.80, 95% CI 1.17 to 6.68; p = 0.02) and use of intraaortic balloon (OR 15.51, 95% CI 4.65 to 51.64; p < 0.0001) were independent correlates of CIN. Patients developing CIN had longer hospital stay (13 +/- 7 days vs. 8 +/- 3 days; p < 0.001), more complicated clinical course, and significantly higher mortality rate (31% vs. 0.6%; p < 0.001). CONCLUSIONS Contrast-induced nephropathy frequently complicates primary PCI, even in patients with normal renal function. It is associated with higher in-hospital complication rate and mortality. Thus, preventive strategies are needed, particularly in high-risk patients.

Abstract
Renal failure is a marker of poor outcome in the general population. Renal failure after percutaneous coronary artery intervention (PCI) is associated with an increased hazard of in-hospital mortality. We hypothesized that post-PCI renal insufficiency would be a predictor of long-term mortality in patients undergoing PCI who survive for over 30 days after the procedure. A retrospective analysis was conducted from a registry of 9,067 patients undergoing PCI at our center from 1997 to 2001. A rise in creatinine by 1 mg/dl from baseline was defined as post-PCI renal insufficiency. Vital status was assessed using Social Security Death Index. There were a total of 996 deaths over a mean follow-up period of 3.2 years. In a multivariate analysis, history of recent acute myocardial infarction, older age, insulin-dependent diabetes, baseline creatinine greater than 1.5 mg/dl, and presence of mitral regurgitation were associated with post-PCI renal insufficiency. Developing post-PCI renal insufficiency was associated with a 4.31-fold hazard of mortality in univariate analysis and a 1.77-fold hazard after adjustment for known predictors of mortality after PCI. The 1-year survival in patients with renal failure was 70.3% +/- 3.91%, compared to a survival of 93.6% +/- 0.27% in those without any post-PCI renal insufficiency (P < 0.0001). Acute renal insufficiency after PCI is a strong and independent predictor of long-term mortality in patients who survived for 30 days after the procedure.

Abstract
Patients who have kidney disease receive aspirin, beta blockers, lipid-lowering therapy, thrombolytic agents, and coronary interventions less often than patients who have normal kidney function. The odds of dying during hospitalization for acute myocardial infarction were significantly higher among patients who had kidney disease than among those who did not have kidney disease after adjusting for several demographic and clinical confounders and year of hospitalization.

Abstract
BACKGROUND Survival after cardiac transplantation has not changed over the last 10 years. Our objective was to identify risk factors for 30-day mortality after cardiac transplantation with particular reference to focusing on the impact of pre-existing renal dysfunction. METHODS We analyzed the data of all 1,180 patients who received a first heart transplant in the 8 adult transplant centers in the United Kingdom between April 1996 and March 2002 using the UK Cardiothoracic Transplant Audit database. Renal function at registration and transplantation was determined by calculation of creatinine clearance (CrCl) according to the Cockcroft-Gault formula. RESULTS Multivariate analysis showed that ventilator dependence pre-transplantation and cold ischemia time >4 hours had the highest association with 30-day mortality, followed by CrCl </=50 ml/min. Patients with a CrCl </=50 ml/min on day of transplantation had a significantly higher 30-day mortality compared to patients with CrCl >50 ml/min (19.7% vs 9.5%; p < 0.01). The change in CrCl between registration and transplantation was not related to mean CrCl or waiting time. In 67 of the patients with a CrCl >50 ml/min at registration, CrCl was reduced to </=50 ml/min on day of transplantation (30-day mortality 16.7%). CONCLUSIONS Pre-operative CrCl </=50 ml/min doubles the risk of death within 30 days after cardiac transplantation. Patients considered for cardiac transplantation should undergo regular measurement of renal function so that a more accurate risk-benefit assessment can be made.

Abstract
Chronic kidney disease (CKD) is a frequent complication of diabetes mellitus. However, the role of CKD in outcomes of patients with diabetes who have undergone percutaneous coronary intervention (PCI) has not been studied specifically. Therefore, we investigated the impact of CKD on prognosis of patients with diabetes who underwent PCI. Of 1,575 diabetic patients who underwent PCI, 1,046 (66%) had preserved renal function, 492 (31%) had CKD (baseline serum creatinine >1.5 mg/dl or estimated glomerular filtration rate <60 ml/min/1.73 m(2)) without dialysis, and 37 (2.3%) were dependent on dialysis. Patients with CKD versus those without CKD had more in-hospital complications, including mortality (2.6% vs 0.5%, respectively; p <0.0001), neurologic events (3.1% vs 0.6%, p = 0.0001), and gastrointestinal bleeding (2.9% vs 0.9%, p = 0.01). Contrast-induced nephropathy after PCI (increase > or =25% and/or > or =0.5 mg/dl of serum creatinine before PCI vs 48 hours after PCI) was found in 15% of patients without CKD versus 27% of those with CKD, and de novo dialysis was instituted in 0.1% versus 3.1%, respectively. Contrast-induced nephropathy was independently predicted (all p <0.0001) by peri-PCI hypotension (odds ratio [OR] 2.62), insulin treatment (OR 1.84), and volume of contrast medium (OR 1.30). The 1-year mortality rate was strikingly higher (all p <0.0001) in patients with CKD who did not receive dialysis (16%) and those on dialysis (44%) compared with the group with preserved renal function (5%). Contrast-induced nephropathy was among the independent predictors of a 1-year mortality rate (OR 2.75, p <0.001).

Abstract
Anemia and renal insufficiency impart an increased risk of mortality in patients with congestive heart failure. There is a paucity of data on the mortality hazard associated with anemia and renal insufficiency in patients undergoing percutaneous coronary intervention in the setting of contemporary practice. We analyzed the short- and long-term outcomes among patients enrolled in EPIC, EPILOG and EPISTENT trials according to degree of kidney dysfunction (glomerular filtration rate [GFR] <60, 60 to 75, and >75 ml/min/1.73 m2) and by hematocrit (<35, 35 to 39 and 40). GFR was calculated as GFR = 186 x (serum creatinine-1.154) x (age-0.203) x 1.212 (if black) or x 0.742 (if female). There were 20 deaths (3.2%) among 638 patients with a hematocrit of <35, 41 deaths among 2,066 patients (2.0%) with a hematocrit of 35 to 39, and 43 deaths in 3,618 patients (1.2%) with a hematocrit >40 at 6 months (p <0.001). Similarly, a significant increase in mortality was seen with lower GFR [33 of 1,168 (2.9%) at GFR <60, 33 of 1,766 (1.9%) at GFR 60 to 75 and 37 of 3,317 (1.1%) at GFR >75, p <0.001)]. Further, GFR and anemia independently and in combination predicted mortality at 3 years. Thus, renal insufficiency and anemia are significant independent and additive predictors of short- and long-term complications in patients undergoing percutaneous coronary intervention.

Abstract
In patients with chronic renal insufficiency, further decline in renal function (DRF) after percutaneous coronary intervention (PCI) is accompanied not only by adverse in-hospital events but also by increased risk of mortality and myocardial infarction at 1 year. This analysis was undertaken to determine if patients with normal renal function who develop DRF after PCI have a comparable increase in risk of death and myocardial infarction at 1 year, and whether this risk is independent of in-hospital complications (death, myocardial infarction, urgent coronary artery bypass grafting). We performed a retrospective analysis of all patients from a single center who underwent successful PCI with no major in-hospital complications who had pre-PCI serum creatinine (SCr) </= 1.2 mg/dl and no history of renal insufficiency. One-year follow-up was obtained by mail or telephone. There were 5,967 consecutive patients who met the inclusion criteria. Of these, 208 (3.5%) developed DRF (an increase in SCr >/= 50% of baseline). They were more likely to be older, female, non-Caucasian, diabetic and/or hypertensive. They reported more prior cerebral or peripheral vascular events. They had undergone more complex PCI and were exposed to more radiographic contrast than the 96.5% who did not develop DRF. After adjustment for baseline variables, DRF remained an independent predictor of 1-year mortality, myocardial infarction, and target vessel revascularization. In patients without prior renal impairment, DRF post-PCI is rare but is associated with an increased risk of late adverse cardiac events similar to that in chronic renal insufficiency patients.

Abstract
PURPOSE To examine long-term survival after angioplasty and stenting of atherosclerotic renal artery stenosis (RAS). METHODS Over a 5-year period, 241 consecutive patients (153 men; mean age 67+/-9 years, range 44-84) were treated with angioplasty and stent implantation for 355 ostial renal stenoses >70%. The procedures were performed in standard fashion using a variety of stents. For survival analysis, the patients were divided into 3 groups based on baseline creatinine levels: group 1: 115 (48%) patients with normal renal function (creatinine <1.2 mg/dL); group 2: 93 (39%) patients with moderately impaired renal function (creatinine 1.2 to 2.5 mg/dL); and group 3: 33 (13%) patients with severely impaired renal function (creatinine >2.5 mg/dL). RESULTS All patients were treated successfully without any procedure-related mortality. The 30-day mortality was 0.4% (1/241). Twenty-two patients died during a follow-up of 27+/-15 months (range 1-60) (overall survival 91%). The causes of death were cardiac (congestive heart failure or myocardial infarction, 73%), stroke (13.5%), and malignant disease (13.5%). The survival rate was significantly lower (29.6%) in patients with a baseline serum creatinine >2.5 mg/dL (p<0.0001) than in groups 2 (89.1%) or 1 (95.4%). Long-term survival without hemodialysis or restenosis was 66.6% at 48 months. Independent predictors for a reduced survival were left ventricle function (HR 2.59, 95% CI 1.45 to 4.63, p=0.001 for each 15% incremental decrease), age (HR 1.13, 95% CI 1.03 to 1.25, p=0.011), and baseline renal function (HR 1.58, 95% CI 1.10 to 2.29, p=0.014). CONCLUSIONS Survival after successful stenting for severe ostial RAS depends on baseline serum creatinine and left ventricle function. Efforts must be made to avoid the development of advanced ischemic nephropathy and congestive heart failure.

Abstract
Cardiovascular disease (CVD) is a major contributor to the mortality and morbidity of patients who suffer from chronic kidney disease (CKD). Heart failure and ischemic heart disease (IHD) are both highly prevalent in this population. The diagnosis of myocardial dysfunction is usually based on echocardiography. As in the general population, systolic dysfunction is treated with a combination of diuretics, renin-angiotensin system blockade, and beta-receptor antagonists. Diastolic dysfunction is best managed by eliminating the cause. Non-invasive tests for coronary artery disease (CAD) may be less reliable in patients with renal disease compared with nonuremic patients. Medical therapy of IHD in this population is generally similar to that for other patient groups, but surgical revascularization appears to carry a higher risk of complications with poorer clinical outcomes. The choice of revascularization procedure (coronary artery bypass grafting versus percutaneous transluminal angioplasty) should be based on the specific coronary anatomy of a given patient as well as a consideration of other comorbid factors.

Abstract
BACKGROUND Patients with moderate chronic renal failure have recently been identified to suffer from a markedly higher mortality after percutaneous coronary intervention (PCI). We focused on the outcome of PCI patients with just mildly elevated creatinine levels of 1.1 to 1.5 mg/dL. METHODS Data of all PCI patients of the years 1998 to 1999 were analyzed. Follow-up was performed by a questionnaire sent to all patients. RESULTS During this period, PCI was performed in 1049 patients. Long-term follow-up (1184 +/- 10 days) was 99.6% complete. Total mortality increased continuously by each creatinine increment of 0.1 mg/dL above 1.0 mg/dL, with a significant difference at 1.3 mg/dL compared to patients with <or=1.0 mg/dL (12.4 vs. 5.5%, P < 0.05). In a Kaplan-Meier model, patients with a creatinine of 1.3 to 1.4 mg/dL had a significantly lower cumulative survival after three years (87%) than controls (96%, P = 0.0108, log rank test). Higher serum creatinine levels were found to be significantly associated with death in univariate analysis (1.1 +/- 0.4 vs. 1.5 +/- 1.0 mg/dL, P < 0.00001), and in multivariate analysis by stepwise logistic regression (OR 2.122, 95% CI 1.585 to 2.841). CONCLUSIONS In this retrospective cross-sectional study, even patients with slightly elevated serum creatinine levels of 1.3 to 1.4 mg/dL had a significantly reduced long-term outcome after PCI. Thus, even mild chronic renal failure appears to be associated with markedly increased risk after a PCI, with implications to the high number of patients concerned.

Abstract
In a large phase III study of patients with unstable angina treated with percutaneous transluminal coronary angioplasty (PTCA), the thrombin-specific anticoagulant bivalirudin produced relative risk reductions of 22% (p = 0.039) for ischemic complications and 62% (p < 0.001) for bleeding complications compared with heparin. Subsequent reports have shown that between-treatment differences favoring fewer complications with bivalirudin also extend to high-risk patients. Early heparinization promotes heparin resistance and decreases activated clotting time achieved during PTCA. These effects are relevant to patients with postinfarction angina, which is associated with a greater likelihood of early vessel closure and procedural failure. In 1006 patients with one or both of these risk factors, bivalirudin significantly reduced combined ischemic and bleeding complications compared with heparin (8.6% vs 18%, p < 0.001). Treatment separations favoring bivalirudin increased with risk, suggesting decreased heparin effectiveness in patients at heightened risk. Findings in three additional risk groups-women, the elderly, and patients not receiving glycoprotein IIb/IIIa inhibitors-also showed fewer complications with bivalirudin therapy. Preliminary data suggest that bivalirudin can be combined safely with glycoprotein IIb/Illa antagonists in percutaneous coronary intervention (PCI), including PTCA. An ongoing trial is aimed at determining the efficacy and safety of heparin with planned glycoprotein IIb/IIIa therapy versus bivalirudin with provisional glycoprotein IIb/IIIa therapy. The use of bivalirudin in patients with heparin-induced thrombocytopenia also is being evaluated after favorable findings in early compassionate-use studies. The fact that between-treatment differences favoring bivalirudin were especially outstanding among the high-risk patients considered in this review reinforces the impression that bivalirudin is a promising and unprecedented alternative to heparin in PCI.
