Abstract
AIMS The optimal cut-off value of isolated cardiac biomarker elevation for defining prognostically important percutaneous coronary intervention (PCI)-related myocardial injury is not known. We performed a meta-analysis to evaluate the dose-response relationship between isolated cardiac biomarker elevations and the risk of all-cause mortality following elective PCI. METHODS AND RESULTS Twenty-four prospective studies (44,972 patients) were included. Patients with an isolated elevation of cardiac biomarkers had an increased risk of all-cause mortality when compared to those with no elevations (cardiac troponin I: odds ratio [OR] 1.42, 95% confidence interval [CI]: 1.19-1.69; creatine kinase-MB isoenzyme [CK-MB]: OR 1.43, 95% CI: 1.19-1.70). For the dose-response analysis, elevations of cardiac troponin I >3x or CK-MB >1x the 99th percentile upper reference limit (URL) were associated with increased mortality (cardiac troponin I: OR 1.51, 95% CI: 1.05-2.17; CK-MB: OR 1.25, 95% CI: 1.05-1.48). The pooled OR of mortality for each 3xURL increment of cardiac troponin I or CK-MB was 1.33 (95% CI: 1.15-1.53) and 1.38 (95% CI: 1.30-1.47). CONCLUSIONS We found that a positive dose-response relationship between isolated cardiac troponin I and CK-MB with all-cause mortality and elevated cardiac troponin I >3x or CK-MB >1x the 99th percentile URL was associated with an increased risk of mortality.

Abstract
Coronary artery disease (CAD) is the leading cause of mortality in patients with chronic kidney disease (CKD). Patients with CKD who undergo percutaneous coronary intervention (PCI) may have more ischemic events than patients without CKD. The aim of our study was to determine the incidence of periprocedural myocardial injury (PMI) after elective stent implantation in patients with CKD using the Third Joint ESC/ACCF/AHA/WHF PMI definition.In a single center prospective cohort study, we enrolled 344 consecutive patients who underwent elective PCI in a period of 39 months. Serum troponin I (cTnI) concentrations were measured at baseline and at 8 and 16 hours after PCI. Periprocedural increase of cTnI, according to the most recent PMI definition, was used to define both the presence and intensity of PMI. Patients were further stratified according to the estimated glomerular filtration rate (eGFR) using 4 variable Modification of Diet in Renal Disease (MDRD) equation: control group with eGFR >90 mL/min/1.73 m and the CKD group with eGFR < 90 mL/min/1.73 m, with further subdivision according to the CKD stage.We found no significant difference in the incidence as well as intensity of the PMI in the control (>90 mL/min/1.73 m) and the CKD group (<90 mL/min/1.73 m) both 8 and 16 hours after PCI. When the CKD patients were further subdivided according to their CKD stage, there was again no difference in the intensity or incidence of PMI compared to the control group. Further analyses of our data showed angina pectoris CCS IV, bare metal stent (BMS) implantation, and treatment with angiotensin-converting enzyme inhibitors (ACEI) as independent predictors of PMI. Furthermore, the presence of hypertension was inversely related to the occurrence of PMI.Applying the new guidelines for PMI and using the eGFR equation most suitable for our patients, we found no association between PMI and CKD. Further analyses showed other factors that could potentially influence the occurrence of PMI.

Abstract
OBJECTIVE Coronary angiography is considered to be a safe tool for the evaluation of coronary artery disease and performed in approximately 12 million patients each year worldwide. The aim of our study was to investigate the frequency and predictors of cardiomyocyte injury in patients undergoing elective coronary angiography. METHODS A total of 749 consecutive patients who were scheduled to undergo elective coronary angiography were prospectively analyzed. High-sensitivity cardiac troponin T concentrations were measured both before and after elective coronary angiography (without intervention). Acute cardiomyocyte injury was predefined as an absolute increase in high-sensitivity cardiac troponin T of at least 7 ng/L (if also fulfilling a relative change of >20%). RESULTS Acute cardiomyocyte injury was observed in 101 patients (13.5%, 95% confidence interval [CI], 11.1-16.2). It was independently associated with aortic valve stenosis (odds ratio [OR], 5.4; 95% CI, 3.0-9.8; P <.001), age (OR, 1.05; 95% CI, 1.02-1.08; P <.001), female sex (OR, 3.5; 95% CI, 1.8-6.8; P <.001), contrast volume (OR, 1.006; 95% CI, 1.001-1.012; P = .019 per 10 mL of contrast volume), documented cardiomyopathy (OR, 2.5; 95% CI, 1.0-6.0; P = .045), and mitral regurgitation (OR, 2.3; CI, 1.0-4.9; P = .033). In contrast, operator experience and extent of coronary artery disease were not found to be associated with acute cardiomyocyte injury. CONCLUSIONS Cardiomyocyte injury accompanies elective coronary angiography in 1 of 8 patients. Sex, age, contrast agent volume, and ventricular disease, rather than the extent of coronary artery disease, independently predict cardiomyocyte injury. Further research aiming to reduce the incidence of cardiomyocyte injury seems warranted.

Abstract
Cardiac troponin-I (cTnI) and -T (cTnT) are sensitive and specific markers of myocardial injury. However, the role of increased cTnI and cTnT in percutaneous coronary intervention (PCI)-related myocardial injury remains controversial. In this prospective, single-center and double-blind study, we aimed to determine the diagnostic and prognostic value of cTnI as well as cTnT (cTns) in PCI-related myocardial injury in a Chinese population. A total of 1,008 patients with stable angina pectoris and non-ST-segment elevation acute coronary syndrome were recruited. The levels of cTnI and cTnT were examined before and after PCI. All patients were followed up for 26±9 months to observe the incidence of major adverse cardiac events (MACEs). Our results showed that post-PCI cTnI and/or cTnT levels were increased to more than the 99th percentile upper reference limit (URL) in 133 (13.2%) patients, among which 22 (2.2%) were more than 5 × 99th percentile URL. By univariate analysis, an elevation in cTns after PCI was not an independent predictor of increased MACEs, HR 1.35 (P = 0.33, 95%CI: 0.74–2.46). In conclusion, our data demonstrate that the incidence of PCI-related myocardial injury is not common in a Chinese population and minor elevated cTns levels may not be a sensitive prognostic marker for MACEs.

Abstract
Slight elevations in cardiac troponin I and T are frequently observed after percutaneous coronary intervention (PCI). Contrast-induced acute kidney injury (CI-AKI) is a complex syndrome induced by exposure to intravascular contrast media (CM). Currently, the relationships between the CM, pre-existing kidney insufficiency, CI-AKI, and myonecrosis after elective PCI are unclear. To investigate the relationship between CI-AKI and post-procedural myonecrosis (PMN) after PCI, we analyzed 327 non-ST-segment elevation acute coronary syndrome subjects undertaking elective PCI. The levels of cardiac troponins (cTns), cTnI and cTnT, at baseline and on at least one occasion 18-24 h after PCI were measured. We also recorded serum levels of creatinine (SCr) and the urine albumin:creatinine ratio (ACR) before coronary angiography, and 24-48 h and 48-72 h after contrast administration. A post-procedure increase in cTns was detected in 16.21% (53/327) of subjects with cTns levels >99th to 5×99th percentile upper reference limit (URL). Twenty-seven patients (8.26%) developed CI-AKI. CI-AKI occurred more often in subjects with PMN than in those without PMN (20.8% versus 5.8%, respectively, P=0.001). Multiple logistic regression analysis revealed that pre-existing microalbuminuria (MA) was an important independent predictor of PMN (OR: 3.31; 95% CI: 1.26-8.65, P=0.01). However, there was no correlation between the incidence of CI-AKI and PMN (OR: 2.38; 95% CI: 0.88-6.46, P=0.09). We conclude that pre-existing MA was not only an important independent predictor of CI-AKI but also of PMN.

Abstract
OBJECTIVES We compared the incidence of late increase in hs-cTnI between ACS and non-ACS patients treated with standard of care with or without darapladib. METHODS A total of 323 (161 ACS and 162 non-ACS patients) were included. High sensitivity troponin I was measured at baseline and at 4, 13, 26 and 52 weeks. RESULTS ACS patients had statistically higher hs-cTnI values during longer term follow-up at which these patients were no longer in the acute setting of myocardial ischemia, but were regarded to have stable CAD (mean hsTnI value in ACS patients: 1.180 versus 0.886 ng/L in non-ACS patients, p = 0.02). Multivariate logistic regression revealed three predictors of any 2-fold increase in hs-cTnI levels compared to the previous visit when interactions were not considered. Treatment with darapladib (adjusted OR 0.53; 95% CI: 0.30-0.92) and initial presentation with ACS (adjusted OR 0.42; 95% CI: 0.23-0.77) were associated with less frequent occurrence of a 2-fold increase in hs-cTnI levels. In contrast, diabetes was associated with a higher incidence of 2-fold increases in hs-cTnI levels (adjusted OR 2.20; 95% CI: 1.04-4.64). Logistic regression to predict any 2-fold increase in hs-cTnI by ACS status showed that in the ACS group, treatment with darapladib decreased the risk of elevation of hs-cTnI (OR 0.219; 95% CI: 0.087, 0.553, p = 0.0013). CONCLUSION In patients with ACS, treatment with darapladib is associated with less increase in cardiac troponin I compared to standard of care alone. This beneficial effect may be associated with darapladib's capability of reducing necrotic core in coronary plaques.

Abstract
OBJECTIVES The aim of this meta-analysis was to assess the prevalence and prognostic value regarding mortality of cTnT or cTnI elevations after nonemergent percutaneous coronary intervention (PCI) in a large number of cohort/registry studies. BACKGROUND Routine cardiac troponin measurement after elective PCI has been controversial among interventionalists. Recent studies have provided conflicting data in regard to predictive value of cardiac troponin-T (cTnT) and troponin-I (cTnI) elevation after non-emergent PCI. METHODS Electronic and manual searches were conducted of all published studies reporting on the prognostic impact of cTnT or cTnI elevation after elective PCI. A meta-analysis was performed with all-cause mortality at follow-up as the primary endpoint. RESULTS We identified 22 studies, involving 22,353 patients, published between 1998 and 2009. Postprocedural cTnT and cTnI were elevated in 25.9% and 34.3% of patients, respectively. Follow-up period ranged from 3 to 67 months (mean: 17.7 ± 14.9 months). The results showed no heterogeneity among the trials (Q-test: 25.39; I(2) : 17%; P = 0.23). No publication bias was detected (Egger's test: P = 0.16). The long-term all-cause mortality in patients with cTnI or cTnT elevation after PCI (5.8%) was significantly higher when compared to patients without cTnI or cTnT elevation (4.4%); OR 1.45 (95% CI: 1.22-1.72), P < 0.01. In addition, the postprocedural composite adverse clinical events of all-cause mortality or myocardial infarction (MI) in patients with cTnI or cTnT elevation after PCI (9.2%) was significantly higher when compared to patients without cTnI or cTnT elevation (5.3%); OR 1.77 (95% CI: 1.48-2.11), P < 0.01. CONCLUSIONS The current meta-analysis indicates that cTnI or cTnT elevation after nonemergent PCI is indicative of an increase in long-term all-cause mortality as well as the composite adverse events of all-cause mortality and MI. Efforts to routinely monitor periprocedural cTn levels along with more intensive outpatient monitoring/treatment of patients with cTn elevations may help to improve the long-term adverse outcomes in these patients following non-emergent PCI.

Abstract
Increases of creatine kinase (CK) and CK-MB cardiac enzymes after nonemergent percutaneous coronary intervention (PCI) have been associated with an increased risk of cardiovascular events during follow-up. However, there are limited data about the incidence and prognostic significance of an isolated increase of cardiac troponin I (cTnI) without an increase in CK-MB after PCI. The aim of this study was to evaluate the impact of an isolated cTnI increase on long-term survival in patients undergoing nonemergent PCI with normal CK-MB levels after PCI. Using the 2004/2005 Cornell Angioplasty Registry, we evaluated the clinical outcomes in 1,601 patients (undergoing elective or urgent PCI) with normal preprocedure cTnI and CK-MB and normal CK-MB levels after the procedure. Patients were divided into 2 groups based on the presence of cTnI increase after PCI. The mean follow-up period was 24.6 +/- 7.6 months. An increase in cTnI was observed in 831 patients (51.9%). Drug-eluting stents were used in 87% of patients and glycoprotein IIb/IIIa inhibitors were administered in 48% of patients. Incidence of in-hospital major adverse cardiovascular events was low, 0.1% versus 0% (p = 1.000), in patients with versus without cTnI increases, respectively. By 2 years of follow-up, Kaplan-Meier survival rates were 94.1% versus 96.4% (log-rank p = 0.020) in those with versus without cTnI increases, respectively. By multivariate Cox regression analysis, an increase in cTnI after PCI (hazard ratio 1.62, 95% confidence interval 1.01 to 2.59, p = 0.047) was an independent predictor of increased long-term mortality. In conclusion, an isolated increase in cTnI after nonemergent PCI is common, not associated with more frequent adverse in-hospital outcomes compared to patients with normal cTnI, and provides long-term prognostic information regarding mortality.

Abstract
AIM Elevation of Troponin after scheduled percutaneous coronary intervention (PCI) is a recognized consequence. We sought to evaluate the prognostic significance and impact of the newly published definition of PCI-related myocardial infarction (MI) according to which any troponin elevation >3 times the upper reference limit identify a peri-procedural MI. METHODS Search of BioMedCentral, CENTRAL, mRCT and PubMed (updated May 2008). Outcomes of interest were: MACE [the composite of all cause death, MI, repeat target vessel PCI (re-PCI) and coronary artery bypass grafting (CABG)]; single end points were also assessed. RESULTS Fifteen studies have been included totalling 7578 patients. Troponin elevation occurred in 28.7% of the procedures. The incidence of PCI-related MI according to the new definition was 14.5%. During the hospitalization, any level of raised troponin was associated with an increased risk of MACE [OR 11.29 (3.00-42.48), Number needed to harm (NNH) 5], death [OR 7.16 (1.95-26.27), NNH = 100], MI [OR 30.85 (6.05-157.38), NNH = 4] and re-PCI [OR 4.13 (1.23-13.88), NNH = 50]. Patients with PCI-related MI had an increased risk of death [OR 17.25 (2.71-109.96), NNH = 100] and re-PCI [OR 10.86 (3.2-36.94), NNH = 25]. At follow up of 18 months any troponin elevation was associated with an increased risk of MACE [OR 1.48 (1.12-1.96), NNH = 20], death [OR 2.19 (1.59-3.00), NNH = 50], MI [OR 3.29 (2.71-6.31), NNH = 33] and re-PCI [OR 1.47 (1.06-2.03), NNH = 25]. In patients with PCI-related MI the risk of MACE was further increased: OR 2.25 (1.26-4.00), NNH = 3. An increase of the troponin level below the cut-off was not associated with MACE. CONCLUSION A diagnosis of MI according to the new guidelines applies to 15% of patients undergoing PCI and these patients are at high risk of further adverse events both during the hospital stay and at 18 months.

Abstract
BACKGROUND Elevations in troponin T (TnT) occur frequently following percutaneous coronary intervention (PCI) and are associated with an adverse prognosis. The Joint ESC/ACC/AHA/WHF Task Force have released a proposal for a universal definition of myocardial infarction (MI), including diagnostic criteria for PCI associated MI. This is based on a TnT cut-point of more than three times the 99th percentile (0.03 ng/ml), which better reflects the precision of the assay. Our study investigated the incidence and predictive factors of a PCI associated MI, using the revised definition. METHODS 325 patients were studied following PCI with stenting. TnT was collected at both 8 and 18 h following PCI in patients with either stable or unstable angina and normal baseline TnT levels. Comparison was made of both clinical and procedural characteristics of patients with and without a rise in TnT following intervention, using cut points of 0.01 and 0.03 ng/ml. RESULTS TnT was elevated > or = 0.03 ng/ml in 27% and > or = 0.01 ng/ml in 39% of patients following PCI. Troponin elevation was significantly more likely in those patients who experienced peri-procedural ischemic symptoms or EKG changes, or in whom abciximab was used. The variables associated with a troponin rise showed a greater difference between TnT positive and negative patients when using 0.03 ng/ml compared to 0.01 ng/ml, suggesting that this may be a better definition of PCI-related MI. CONCLUSIONS Approximately one-quarter of low risk patients experience a procedural MI according to the revised definition. Rises in troponin were significantly associated with peri-procedural ischemic symptoms and EKG changes, and abciximab use, consistent with this level of TnT reflecting true myocardial necrosis.

Abstract
BACKGROUND Although the prognostic importance of troponin in patients with anacute coronary syndrome is clear, the significance of troponin elevation after elective percutaneous coronary intervention (PCI) is a subject of debate. However, most studies up to now had a small sample size and insufficient events during follow-up. METHODS Electronic and manual searches were performed of studies reporting on prognosis of troponin after elective PCI. A meta-analysis was done of all suitable studies, with death in follow-up as primary endpoint and the combination of death or nonfatal myocardial infarction in follow-up as secondary endpoint. RESULTS 20 studies involving 15,581 patients were included. These studies were published between 1998 and 2007. Overall, troponin was elevated after elective PCI in 32.9% of patients. The follow-up period varied between 3 and 67 months (mean 16.3). Increased mortality was significantly associated with troponin elevation after PCI (4.4% vs. 3.3%, P = 0.001; OR 1.35). Furthermore, the combined endpoint of mortality or nonfatal myocardial infarction also occurred more often in patients with post-procedural troponin elevation (8.1% vs. 5.2%, P < 0.001; OR 1.59). CONCLUSIONS According to this meta-analysis, troponin elevation after elective PCI provides important prognostic information.
