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
BACKGROUND Elective percutaneous coronary intervention (ePCI) may cause minor elevation of cardiac enzymes, so-called minor myocardial injury (MMI) which can be due to different pathophysiological mechanism (e.g. distal embolisation, side branch occlusion, increased platelet activation triggered by the intracoronary metallic stents). We aimed to compare the effectiveness of ticagrelor versus clopidogrel for the prevention of MMI and major adverse clinical events (MACEs) after ePCI. METHODS Study population consisted of two groups of patients based on the treatment: Group I, receiving clopidogrel (n = 104), Group II, receiving ticagrelor (n = 96). Cardiac troponin I (cTnI), CK-MB were studied before and 12 hours after the procedure. Elevation of cTnI greater than 0.06 ng/ml was considered as MMI. All patients were also evaluated for the MACEs (death, myocardial infarction, stroke and transient ischaemic attack). RESULTS Fifty-two of 200 patients (26%) had MMI after the procedure. The minor myocardial injury was significantly more prevalent in clopidogrel group than that of ticagrelor group (33% vs. 19%, p = .03). Myocardial infarction (MI) and MACEs were significantly higher in the clopidogrel group (15% vs. 6%, for MI, p = .04; 16% vs. 6%, for MACEs, p = .03, respectively). Multivariate analysis demonstrated antiplatelet treatment, saphenous graft intervention, type-C lesion as independent predictors of MMI. CONCLUSIONS Present study showed that the combination of ticagrelor and aspirin was more effective than combination of clopidogrel and aspirin in decreasing MMI and MACEs after elective stenting.

Abstract
BACKGROUND The aim of our study was to assess the effect of pretreatment with cilostazol and rosuvastatin combination before elective percutaneous coronary intervention (PCI) on peri-procedural myocardial injury (PPMIJ). METHODS We randomly assigned 172 patients with stable angina pectoris scheduled for elective PCI to pre- treatment with Cilostazol 200mg and Rosuvastatin 40 mg (group 1), or to pretreatment with Rosuvastatin 40 mg group (group 2). The primary end-point was the occurrence of PPMIJ defined as any cardiac troponin I (Tn I) level elevated above the upper normal limit (UNL). The occurrence of peri-procedural myocardial infarction (PPMIN) was defined as a post-procedural increase in cTnI level ≥ 5 times above the UNL. RESULTS There was no significant difference in baseline characteristics between group 1 (n = 86) and group 2 (n = 86). The rate of PPMIJ (21% vs. 24%, p = 0.58) and PPMIN (2.3% vs. 7%, p = 0.27) were similar between the two study groups. Subgroup analysis performed on those patients without statin therapy before PCI (53 patients in group 1 and 50 patients in group 2) showed that the incidence of PPMIJ was significantly lower in the group 1 patients without chronic statin treatment [17% (9/53) versus 34% (17/50); p = 0.04], but the rate of PPMIN was similar between the two groups for those patients without chronic statin treatment [1.9% (1/53) versus 10% (5/50); p = 0.07]. CONCLUSIONS We found that adjunct cilostazol and rosuvastatin pre-treatment did not significantly reduce PPMIJ after elective PCI in patients with stable angina pectoris. However, adjunct cilostazol pre-treatment could reduce PPMIJ in patients without chronic statin therapy before elective PCI.

Abstract
INTRODUCTION Thirty-day readmission rates after percutaneous coronary intervention (PCI) have been related to adverse prognosis, and represent one of the most investigated indicators of quality of care. These data, however, derive from non-European centers evaluating all-cause readmissions, without stratification for diagnosis. METHODS All consecutive patients undergoing PCI at our center from January 2009 to December 2011 were enrolled. Thirty-day readmissions related to postinfarction angina, myocardial infarction, unstable angina or heart failure were defined as acute coronary syndrome (ACS) or heart failure rehospitalizations. Major cardiac adverse event (MACE) was the primary outcome, and its single components (death, myocardial infarction and repeated revascularization) the secondary ones. RESULTS A total of 1192 patients were included; among them, 53 (4.7%) were readmitted within 30 days, and 25 (2.1%) were classified as ACS/heart failure related. During hospitalization, patients with ACS/heart failure readmissions were more likely to suffer a periprocedural myocardial infarction (22 vs. 4%; P = 0.012), and to undergo PCI at 30 days (52 vs. 0.5%; P < 0.001). Logistic regression analysis indicated that periprocedural myocardial infarction represented the only independent predictor of an ACS/heart failure readmission [odds ratio (OR) 4.5; 1.1-16.8; P = 0.047]. After a median follow-up of 787 days (434-1027; first and third quartiles), patients with a 30-day ACS/heart failure readmission experienced higher rates of MACE, all-cause death and myocardial infarction (64 vs. 21%, P < 0.001; 28 vs. 6%, P = 0.017; and 20 vs. 2.7%, P < 0.001, respectively). Cox multivariate analysis indicated that ACS/heart failure 30-day readmissions were independently related to an increased risk of all-cause death (OR 3.3; 1.1-8.8; P = 0.02), differently from 30-day non-ACS/heart failure readmissions (OR 3.1; 0.7-12.9; P = 0.12). CONCLUSION Thirty-day readmissions after PCI in an Italian center are infrequent, and only those patients with ACS/heart failure show a detrimental impact on prognosis who have periprocedural myocardial infarction as the only independent predictor.

Abstract
Aims We studied the utility of multimarker risk stratification approach to predict cardiovascular outcomes in patients with stable coronary artery disease, undergoing elective percutaneous coronary intervention (PCI). Methods We prospectively evaluated 302 consecutive patients with stable coronary artery disease and normal CPK-MB and cardiac troponin T levels, and who underwent elective PCI at our institution. The following cardiac biomarkers were measured before and between 12 and 24 h post-procedure: CK-MB, cardiac troponin T, hs-CRP, and NT-ProBNP. Patients were followed up for a minimum of 6 months. Results Post-PCI, CPK-MB levels were elevated but below myocardial infarction (MI) range in 70 patients (23%), and in the MI range in 6 patients (2%). Troponin T levels were detectable but below the 99th percentile (microleak) in 32 patients (10.6%) and elevated above the 99th percentile (periprocedural MI) in 104 patients (34.4%). At 9 months’ follow-up, 1% died, 2% had stable angina, 10.3% had non-fatal MI, and 87.7% remained asymptomatic. There was no significant difference in clinical events among groups stratified by elevation of one biomarker or multiple biomarkers. Conclusion Single or multiple biomarker strategy in patients with normal baseline biomarkers failed to predict major cardiac events after PCI over medium-term follow-up.

Abstract
Trimetazidine is an anti-ischemic agent with antioxidant activity. This study evaluated the effect of periprocedural administration of trimetazidine on the incidence of percutaneous coronary intervention (PCI)-induced myocardial injury and contrast-induced nephropathy (CIN) in diabetic patients with mild-to-moderate renal dysfunction. One hundred patients with a mean glomerular filtration rate of 48 ± 16 (ml/min/1.73 m(2)) were prospectively enrolled, then randomly assigned to receive (50 patients; trimetazidine group) or not receive (50 patients; control group) periprocedural trimetazidine (70 mg/day) for 72 hours. The serum creatinine level was measured pre-PCI, 72 hours, and 10 days thereafter. An increase in the serum creatinine level by >0.5 mg/dl or 0.25% of the baseline value is considered as CIN. Cardiac troponin I levels were measured before and 6, 12, and 24 hours after PCI. Mean age of the study cohort was 59 ± 6 years (men 68%). The serum creatinine level in the control group increased significantly 3 days after PCI and decreased on the tenth day. However, it showed no significant change in the trimetazidine group. Incidence of CIN was 12% in the trimetazidine group and 28% in the control group (p <0.05). Cardiac troponin I levels were significantly reduced in the trimetazidine group (6 hours: 8 ± 0.3 vs 16 ± 0.2 pg/ml, 12 hours: 13 ± 0.9 vs 24 ± 0.8 pg/ml, 24 hours: 7 ± 0.7 vs 14 ± 0.3 pg/ml, p <0.001). In conclusion, trimetazidine intake before elective PCI in diabetic patients with mild-to-moderate renal dysfunction is associated with decreased incidence of CIN and myocardial injury.

Diagnostic and prognostic value of minor elevated cardiac troponin levels for percutaneous coronary intervention-related myocardial injury: a prospective, single-center and double-blind study. J Biomed Res 2014; 28:98-107.

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
Numerous definitions have been proposed for the diagnosis of myocardial infarction (MI) after coronary revascularization. The universal definition for MI designates post procedural biomarker thresholds for defining percutaneous coronary intervention (PCI)-related MI (type 4a) and coronary artery bypass grafting (CABG)-related MI (type 5), which are of uncertain prognostic importance. In addition, for both the MI types, cTn is recommended as the biomarker of choice, the prognostic significance of which is less well validated than CK-MB. Widespread adoption of a MI definition not clearly linked to subsequent adverse events such as mortality or heart failure may have serious consequences for the appropriate assessment of devices and therapies, may affect clinical care pathways, and may result in misinterpretation of physician competence. Rather than using an MI definition sensitive for small degrees of myonecrosis (the occurrence of which, based on contemporary large-scale studies, are unlikely to have important clinical consequences), it is instead recommended that a threshold level of biomarker elevation which has been strongly linked to subsequent adverse events in clinical studies be used to define a "clinically relevant MI." The present document introduces a new definition for "clinically relevant MI" after coronary revascularization (PCI or CABG), which is applicable for use in clinical trials, patient care, and quality outcomes assessment.

Abstract
OBJECTIVES This study investigated the influence of intracoronary enalaprilat on coronary microvascular function and peri-procedural outcome measures in patients with stable angina undergoing percutaneous coronary intervention (PCI). BACKGROUND Intracoronary angiotensin-converting enzyme inhibitors have been shown to relieve myocardial ischemia in stable patients and to improve epicardial flow in patients with ST-segment elevation myocardial infarction. Yet, it is still unclear whether these effects are mediated by a modulation of the coronary microcirculation. METHODS We randomly assigned 40 patients to receive either an intracoronary bolus of enalaprilat (50 μg) or placebo before elective PCI. The index of microvascular resistance was measured at baseline, 10 minutes after study drug administration, and after PCI. High-sensitivity cardiac troponin T was measured as a marker of myocardial injury. RESULTS Infusion of enalaprilat resulted in a significant reduction in index of microvascular resistance (27 ± 11 at baseline vs. 19 ± 9 after drug vs. 15 ± 8 after PCI), whereas a significant post-procedural increase in index of microvascular resistance levels was observed in the placebo group (24 ± 15 at baseline vs. 24 ± 15 after drug vs. 33 ± 19 after PCI). Index of microvascular resistance levels after PCI were significantly lower in the enalaprilat group (p < 0.001). Patients pre-treated with enalaprilat also showed lower peak values (mean: 21.7 ng/ml, range: 8.2 to 34.8 ng/ml vs. mean: 32.3 ng/ml, range: 12.6 to 65.2 ng/ml, p = 0.048) and peri-procedural increases of high-sensitivity cardiac troponin T (mean: 9.9 ng/ml, range: 2.7 to 19.0 ng/ml vs. mean: 26.6 ng/ml, range: 6.3 to 60.5 ng/ml, p = 0.025). CONCLUSIONS Intracoronary enalaprilat improves coronary microvascular function and protects myocardium from procedure-related injury in patients with coronary artery disease undergoing PCI. Larger studies are warranted to investigate whether these effects of enalaprilat could result into a significant clinical benefit.

Comparison of frequency of periprocedural myocardial infarction in patients with and without diabetes mellitus to those with previously unknown but elevated glycated hemoglobin levels (from the TWENTE Trial). Am J Cardiol 2012; 110:1561-7. [PMID: 22939581 DOI: 10.1016/j.amjcard.2012.07.019] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2012] [Revised: 07/12/2012] [Accepted: 07/12/2012] [Indexed: 11/21/2022]
Abstract
In patients without a history of diabetes mellitus, increased levels of glycated hemoglobin (HbA1c) are associated with higher cardiovascular risk. The relation between undetected diabetes and clinical outcome after percutaneous coronary intervention is unknown. To investigate whether these patients may have an increased risk of periprocedural myocardial infarction (PMI), the most frequent adverse event after percutaneous coronary intervention, we assessed patients of the TWENTE trial (a randomized, controlled, second-generation drug-eluting stent trial) in whom HbA1c data were available. Patients were classified as known diabetics or patients without a history of diabetes who were subdivided into undetected diabetics (HbA1c ≥6.5%) and nondiabetics (HbA1c <6.5%). Systematic measurement of cardiac biomarkers and electrocardiographic assessment were performed. One-year clinical outcome was also compared. Of 626 patients, 44 (7%) were undetected diabetics, 181 (29%) were known diabetics, and 401 (64%) were nondiabetics. In undetected diabetics the PMI rate was higher than in nondiabetics (13.6% vs 3.7%, p = 0.01) and known diabetics (13.6% vs 6.1%, p = 0.11). Multivariate analysis adjusting for covariates confirmed a significantly higher PMI risk in undetected diabetics compared to nondiabetics (odds ratio 6.13, 95% confidence interval 2.07 to 18.13, p = 0.001) and known diabetics (odds ratio 3.73, 95% confidence interval 1.17 to 11.89, p = 0.03). After 1 year, target vessel MI rate was significantly higher in undetected diabetics (p = 0.02) than in nondiabetics, which was related mainly to differences in PMI. Target vessel failure was numerically larger in unknown diabetics than in nondiabetics, but this difference did not reach statistical significance (13.6% vs 8.0%, p = 0.25). In conclusion, undetected diabetics were shown to have an increased risk of PMI.

Abstract
Serum cardiac troponin T (cTnT) and CKMB (mass) were analysed in three groups of patients. The first group (n=32) were patients with acute coronary syndromes including myocardial infarction. The second group (n=35)were patients with hypertension. The third group (n=24) were patients who had succumbed to non cardiac diseases. In all 3 groups, cardiac troponin T was elevated when compared with controls (p<0.001). However, CKMB elevation was not significant in all groups. CKMB levels correlated well with troponin T levels only when CKMB was greater than 50 ng/ml (r=1.00). Small elevations of troponin T identifies minimal cardiac necrosis and patients can benefit from early invasive therapy.

Abstract
BACKGROUND Periprocedural myocardial infarction (MI) occurs in a significant proportion of patients undergoing percutaneous coronary intervention (PCI) and portends poor outcomes. Currently, no clinically applicable method predicts periprocedural MI in the cardiac catheterization laboratory before it occurs. We hypothesized that impaired baseline coronary microcirculatory reserve, which reduces the ability to tolerate ischemic insults, is a risk for periprocedural MI and that the index of microcirculatory resistance (IMR) measured during PCI can predict occurrence of periprocedural MI. METHODS AND RESULTS Consecutive patients undergoing elective PCI of a single lesion in the left anterior descending coronary artery were recruited. A pressure-temperature sensor wire was used to measure IMR before PCI. Of the 50 patients studied, 10 had periprocedural MI. From binary logistic regression analyses of all clinical, procedural, and physiological parameters, univariable predictors of periprocedural MI were pre-PCI IMR (P=0.003) and the number of stents used (P=0.039). Pre-PCI IMR was the only independent predictor in bivariable regression analyses performed by adjusting for each available covariate one at a time (all P≤0.02). Pre-PCI IMR ≥27 U had 80.0% sensitivity and 85.0% specificity for predicting periprocedural MI (C statistic, 0.80; P=0.003). Pre-PCI IMR ≥27 U was independently associated with a 23-fold risk of developing periprocedural MI (odds ratio, 22.7; 95% CI, 3.8-133.9). CONCLUSIONS These data suggest that the status of the coronary microcirculation plays a role in determining susceptibility toward periprocedural MI at the time of elective PCI. The IMR can predict subsequent risk of developing myocardial necrosis and may guide adjunctive prevention strategies.

Abstract
In recent years, percutaneous coronary intervention (PCI) has become a well-established technique for the treatment of coronary artery disease. PCI improves symptoms in patients with coronary artery disease and it has been increasing safety of procedures. However, peri- and post-procedural myocardial injury, including angiographical slow coronary flow, microvascular embolization, and elevated levels of cardiac enzyme, such as creatine kinase and troponin-T and -I, has also been reported even in elective cases. Furthermore, myocardial reperfusion injury at the beginning of myocardial reperfusion, which causes tissue damage and cardiac dysfunction, may occur in cases of acute coronary syndrome. Because patients with myocardial injury is related to larger myocardial infarction and have a worse long-term prognosis than those without myocardial injury, it is important to prevent myocardial injury during and/or after PCI in patients with coronary artery disease. To date, many studies have demonstrated that adjunctive pharmacological treatment suppresses myocardial injury and increases coronary blood flow during PCI procedures. In this review, we highlight the usefulness of pharmacological treatment in combination with PCI in attenuating myocardial injury in patients with coronary artery disease.

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
Background. In acute myocardial infarction, thrombus aspiration prior to percutaneous coronary interventions (PCI) is often beneficial, but this approach has never been studied in patients without acute myocardial infarction. The aim of this retrospective study is to shed light on that topic based on our initial experience with manual thrombus aspiration in patients with stable or unstable angina pectoris and angiographic evidence of lesion-site thrombus. Methods. We assessed the feasibility (thrombus aspiration without predilatation) of this approach; in addition, we determined angiographic coronary flow and myocardial blush grade. Results. During 33 months in which a total of 4725 PCI were performed in our centre, manual thrombus aspiration was attempted in 14 patients with stable or unstable angina pectoris with angiographic evidence of thrombus. In nine of these 14 patients, the aspiration catheter could be advanced into the lesion without predilatation; in eight patients visible thrombus was obtained. The corrected TIMI frame count improved during the entire interventional procedure (21.1±11.2 vs. 12.8±5.9 frames; p=0.015). Myocardial blush grade, which overall improved during PCI (p<0.001), tended to show greater improvement in patients in whom thrombus aspiration could be achieved (1.6±0.9 vs. 0.7±0.5; p=0.06). Conclusions. Preliminary evidence suggests that manual thrombus aspiration may occasionally be considered in selected patients without acute myocardial infarction but with angiographic evidence of lesion-site thrombus. Nevertheless, prospective studies are required to clearly define the role of this approach in clinical practice. (Neth Heart J 2010;18:423-9.).

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
High-sensitivity C-reactive protein predicts future cardiovascular events in both healthy individuals and patients with unstable and stable coronary syndromes. Few data are available about the incidence and the relation to inflammation of troponin elevation following percutaneous coronary intervention (PCI), a potential predictor of longterm outcome. We sought to confirm the impact of embolization on long-term outcome and evaluate the ability of baseline inflammation to predict troponin elevation induced by PCI. We prospectively analyzed 200 patients treated by PCI for stable or Braunwald IIA class unstable angina. The patients were recruited between January 1997 and May 1999, and the population was followed during a mean follow-up of 32 months. Major adverse cardiac events (MACEs) were defined as the occurrence of death, myocardial infarction or recurrent angina requiring repeat PCI, or coronary artery bypass grafting. During the follow-up period, 58 MACEs were observed. By multivariate analysis, independent predictors for the occurrence of MACEs were unstable angina and troponin I level after PCI (P < 0.0001 for both). No correlation was found between baseline inflammation and significant troponin I elevation post PCI and by multivariate analysis, no biological variable was a predictor of troponin I elevation post PCI. Baseline inflammation cannot predict onset of minor myonecrosis damage (expressed by troponin elevation) induced by PCI, a significant predictor of long-term outcome in this setting.

Abstract
INTRODUCTION AND OBJECTIVES To determine whether long-term prognosis is affected by myocardial damage taking place during percutaneous coronary intervention (PCI). METHODS The study included consecutive patients undergoing PCI. Those with elevated baseline cardiac marker levels were excluded. Cardiac markers were evaluated and an ECG was recorded before and 12 and 24 hours after PCI. Patients were divided into three groups after PCI according to their cardiac marker levels: no myocardial damage (i.e. normal troponin and creatine kinase MB fraction [CK-MB]), minor damage (elevated troponin with normal CK-MB), and myonecrosis (elevated troponin and CK-MB). The occurrence of death, myocardial infarction or repeat revascularization during follow-up was recorded. RESULTS Minor myocardial damage associated with PCI was observed in 127 (16.8%) of the 757 patients included in the study and myonecrosis, in 46 (6.1%). During a follow-up of 45+/-14 months, cardiac events occurred in 151 (19.1%) patients. Mortality during follow-up was significantly higher in patients with myonecrosis (13%) than in the other two groups (4.8% and 3.9%; log rank, 6.83; P=.032). No difference was observed in the rate of myocardial infarction or repeat revascularization during follow-up. CONCLUSIONS Minor myocardial damage during PCI had no effect on long-term prognosis. In contrast, myonecrosis was associated with increased mortality. Consequently, the CK-MB level should be measured after all PCIs because of its prognostic implications, and strategies for reducing the risk of myonecrosis developing should be implemented.

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 C-reactive protein (CRP), a marker of inflammation, plays a role in the pathophysiology of atherosclerotic events. The relationship between CRP levels and myocardial necrosis assessed by troponin T (TnT) in patients undergoing percutaneous coronary intervention (PCI) has not been established. In addition, the long-term significance of TnT rise following PCI is not clear. OBJECTIVES To examine the relationship between CRP and the rise in TnT levels, and evaluate the long-term prognostic implications of TnT rise following PCI. METHODS A total of 1208 patients underwent successful nonemergent PCI. Baseline demographic characteristics, CRP and TnT levels were prospectively collected before and 12 h to 18 h following PCI. Long-term follow-up data over two years were available. RESULTS Among the patients studied (mean age 62 years), 64% presented with acute coronary syndrome. A PCI procedure was associated with a significant increase in TnT levels (higher than 0.1 microg/L) in 238 patients (20%). Multivariate logistic regression identified presentation with acute coronary syndrome or myocardial infarction, no statin use at the time of the procedure, increased CRP and increasing length of stent as independent predictors of TnT rise following PCI. Periprocedural TnT rise was not associated with adverse events in follow-up examinations (OR 1.09, 95% CI 0.73 to 1.65). CONCLUSIONS Myocardial necrosis commonly occurred in otherwise successful PCI and was particularly prevalent in the proinflammatory milieu of a recent myocardial infarction. This response was blunted with statin therapy. However, there was no long-term adverse sequelae of these troponin rises following otherwise uncomplicated PCI.

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.

Abstract
BACKGROUND The prognostic importance of elevated cardiac enzymes after elective percutaneous coronary intervention has been debated. Therefore, we performed a prospective observational study to evaluate the prognostic value of postprocedural rise of troponin T and creatine kinase. METHODS Troponin T (cut-off value 0.05 ng/ml) and creatine kinase (cut-off value 180 IU/l with muscle-brain fraction >4%) were measured 12 h after elective percutaneous coronary intervention in 713 consecutive patients without elevated troponin before the procedure. Primary endpoint was the combined incidence of death, myocardial infarction, stroke, repeat angiography or re-admission because of anginal symptoms during the follow-up period. RESULTS Troponin was elevated after the procedure in 150 patients (21%) and creatine kinase in 66 pts (9%), with a strong association between increased troponin and creatine kinase. After a mean follow-up of 10.9 months, mortality was low (1%) and not associated with increased troponin or creatine kinase. There was, however, a strong relation between postprocedural troponin and re-admission for angina (p=0.001) or myocardial infarction (p=0.001). Furthermore, troponin rise was significantly associated with an increased risk of the primary endpoint (relative risk 1.55 95% confidence interval 1.01-2.38). After multivariate analysis, troponin elevation but not increased creatine kinase was associated with an increased risk of the primary endpoint (relative risk 1.59 95% confidence interval 1.02-2.47 for troponin elevation versus 1.16 95% confidence interval 0.62-2.15 for increased creatine kinase). CONCLUSION Increase of troponin T after elective percutaneous coronary intervention has stronger prognostic implication when compared to increased creatine kinase.

Abstract
OBJECTIVE To evaluate the effect of pre-procedural acute oral administration of trimetazidine (TMZ) on percutaneous coronary intervention (PCI)-induced myocardial injury. DESIGN Single-centre, prospective, randomised evaluation study. SETTING Patients with stable angina pectoris and single-vessel disease undergoing PCI. PATIENTS 582 patients were prospectively randomised. Patients who underwent more than one inflation during PCI were excluded, resulting in 266 patients randomly assigned to 2 groups. INTERVENTIONS Patients were randomly assigned to receive or not an acute loading dose of 60 mg of TMZ prior to intervention. MAIN OUTCOME The frequency and the increase in the level of cardiac troponin Ic (cTnI) after successful PCI. cTnI levels were measured before and 6, 12, 18 and 24 h after PCI. RESULTS 136 patients were assigned to the TMZ group and 130 to the control group. Although no statistically significant difference was observed in the frequency of cTnI increase between the two groups, post-procedural cTnI levels were significantly reduced in the TMZ group at all time points (6 h: mean (SD) 4.2 (0.8) vs 1.7 (0.2), p<0.001; 12 h: 5.5 (1.5) vs 2.3 (0.4), p<0.001; 18 h: 9 (2.3) vs 3 (0.5), p<0.001; and 24 h: 3.2 (1.2) vs 1 (0.5), p<0.001). Moreover, the total amount of cTnI released after PCI, as assessed by the area under the curve of serial measurement, was significantly reduced in the TMZ group (p<0.05). CONCLUSION Pre-procedural acute oral TMZ administration significantly reduces PCI-induced myocardial infarction.

Abstract
Serum cardiac enzyme elevation after percutaneous coronary intervention (PCI), a relatively common complication, is a prognostic determinant of long-term outcome in patients who undergo these procedures. Statins are postulated to reduce such complications. This study investigated the short-term effects of pravastatin on serum creatine kinase myocardial isoform (CK-MB) and serum cardiac troponin I (cTpI) levels after elective PCI. Of 93 patients studied, 72 (77.4%) were men, and 21 (22.6%) were women (mean age, 58.9+/-11.0 y). Patients were randomly divided into 3 groups before they underwent elective PCI. Preoperatively, group 1 patients (n=30) received pravastatin 10 mg/d, and group 2 patients (n=29) received pravastatin 40 mg/d. Control group patients (n=34) received no lipid-lowering medication. Serum CK-MB and serum cTpI levels were measured preoperatively and then again at 6, 24, and 36 h postoperatively. Demographic features of patients and characteristics of the PCI procedure, including number of vessels/lesions and duration and number of inflations, did not differ among groups (P>.05). Mean serum CK-MB and serum cTpI levels were significantly increased after PCI in all patients (P<.001). When compared with control group patients, those given pravastatin did not experience significantly lowered postprocedural serum CK-MB or serum cTpI levels (P>.05). Preprocedural pravastatin therapy at dosages of 10 mg/d and 40 mg/d seems inadequate for preventing serum cardiac enzyme elevations during short-term follow-up after PCI. Additional research on this topic is recommended.

Abstract
BACKGROUND Minor myocardial damage after percutaneous coronary intervention (PCI) is associated with cardiac risks, which statins seem to reduce. The aim of this study was to examine whether intensive lipid-lowering therapy is more effective in decreasing the risk of cardiac injury after PCI than moderate lipid-lowering therapy. METHODS AND RESULTS Subjects comprised 42 patients with stable angina without previous statin treatment, randomly assigned to either an intensive lipid-lowering group (Group A: target low-density lipoprotein-cholesterol (LDL-C)<70 mg/dl) or a moderate lipid-lowering group (Group B: target LDL-C<100 mg/dl) 2 weeks before PCI. All patients took statins to reach target LDL-C levels. Incidence of periprocedural myocardial injury was assessed by analyzing levels of creatine kinase myocardial isozyme (CK-MB) and cardiac troponin T (TnT) before and 6, 12 and 24 h after PCI. Minor myocardial damage was defined as TnT elevation to >0.01 ng/ml. Frequency of minor myocardial damage was 14.2% in Group A and 47.6% in Group B (p=0.043). CK-MB was above the upper limit of normal (ULN) in 19% of Group A and 33.3% of Group B (p=0.44), and CK-MB was >3x ULN in 9.5% of Group A and 19% of Group B (p=0.66). CONCLUSIONS Intensive lipid-lowering therapy before PCI reduces minor myocardial damage during PCI with stenting compared with moderate lipid-lowering therapy.

Abstract
All novel markers of myocardial ischemia (ischemia-modified albumin, choline, unbound free fatty acids) lack cardiac specificity. Therefore, for the specific detection of myocardial ischemia selective blood sampling from an inserted coronary sinus catheter is needed, which limits the applicability of these markers in most clinical routine settings. In addition, the superiority of these novel markers over the calculation of myocardial lactate production, the current criterion standard for the laboratory diagnosis of myocardial ischemia, has not been demonstrated so far, and even comparative data is frequently lacking. Further the superiority of these new candidate markers over lactate determination for the diagnosis of myocardial ischemia in peripherally drawn blood samples has not been demonstrated either, and these novel parameters appear not to be a breakthrough for laboratory diagnosis of myocardial ischemia during or after percutaneous coronary interventions or coronary artery bypass grafting. The determination of cardiac troponin I or troponin T is the current criterion standard for the laboratory diagnosis of myocardial damage due to their higher sensitivities and specificities compared to creatine kinase isoenzyme MB. According to current knowledge, troponin increases in peripherally drawn blood samples must be regarded as an indicator of myocardial necrosis which, however, may be limited, only detectable by troponin and may be missed by creatine kinase isoenzyme MB determination. After on-pump coronary artery bypass grafting the generally applied troponin discriminator limits are not valid as there is limited, inevitable cardiac tissue damage occurring during the surgical procedure. Therefore, troponins are significantly increased after reperfusion of the arrested heart over values seen before bypass and also in patients without complications. Perioperative myocardial infarctions can be reliably identified by their characteristic troponin time courses, and both peak concentrations and time of peak values are diagnostic criteria. Troponin release is lower in off-pump compared to on-pump bypass surgery. Despite the controversy over the significance of troponin elevations after clinically uncomplicated and successful procedures, it is tempting to postulate that less myocardial damage as detected by troponin release is beneficial for the patient. After elective percutaneous coronary interventions, only troponin increases >8-fold the upper reference limit were associated with increased mortality in long-term follow-up.

Abstract
BACKGROUND Myocardial necrosis as assessed by cardiac troponin elevation occurs frequently after coronary stenting and is associated with adverse clinical outcome. Mechanical factors have been implicated in this complication and the role of systemic inflammation is not known. METHODS We prospectively studied 208 patients with chronic stable angina who underwent elective coronary stenting. All patients had normal troponin levels before the procedure. Blood samples for high-sensitivity C-reactive protein (CRP) were obtained before the procedure and analyzed using a high-sensitivity kit. Cardiac troponin T (cTnT) was obtained 24 hours after the procedure. RESULTS Postprocedural cTnT elevations were observed in 46 (22%) patients. There were 11 (16%), 14 (20%), and 21 (30%) patients with elevated postprocedural cTnT in the first, second, and third CRP tertile, respectively (P for trend = .045). In a multivariate logistic regression model, adjusting for all the significant univariate predictors and for statin therapy, CRP remained a significant independent predictor of postprocedural cTnT elevation with an odds ratio of 2.6 in patients in the third CRP tertile compared with patients in the first CRP tertile (95% CI 1.1-6.0, P = .02). Patients in the third CRP tertile also had higher cTnT elevations compared with patients in the first and second CRP tertile (P = .03). CONCLUSIONS Elevated baseline CRP levels are associated with higher risk of postprocedural troponin elevations in patients with stable angina undergoing uncomplicated coronary stenting. These results underscore the role of systemic inflammation in the pathogenesis of periprocedural myocardial injury.

Abstract
This study evaluates the association between statin therapy in patients treated by percutaneous coronary intervention (PCI) for stable angina pectoris and postinterventional myocardial injury with subsequent long-term clinical outcome. Prospectively collected data on 400 consecutive patients with stable angina pectoris or evidence of inducible myocardial ischemia were analyzed. The incidence of myocardial infarction based on postinterventional release of troponin I>1.5 ng/ml was 12% in the statin pretreated patients and 20% in those not pretreated with statin therapy (P=0.04, odds ratio 1.84, 95% confidence interval 1.06-3.21). Of the patients experiencing a post-PCI troponin elevation>1.5 ng/ml, those pretreated with a statin pre-PCI had a lesser troponin elevation compared with those not receiving a statin pre-PCI (median: 2.9 ng/ml [1.9-11.5] vs 5.0 ng/ml [3.1-8.8]; P<0.001). In the multivariate model, preprocedural statin therapy was identified as the only independent negative predictor of procedure-related myocardial necrosis based on postprocedural troponin elevation. In the 21-month follow-up period, statin pretreated patients were observed to have fewer deaths, revascularizations, or myocardial infarction; however, this difference was not statistically significant. These results suggest that pretreatment with statins in patients undergoing PCI for stable angina pectoris reduces the risk and extent of procedure-related myocardial injury measured by troponin release.

Abstract
BACKGROUND Minor cardiac marker elevation after percutaneous coronary intervention has long-term prognostic significance. We examined whether nicorandil, a nicotinamide-nitrate ester, reduces the incidence of minor cardiac marker elevation after coronary stenting. METHODS Patients (n=192) undergoing coronary stenting were randomly assigned to receive nicorandil (nicorandil group, n=91) or vehicle (control group, n=101). Nicorandil (2 mug/kg/min, intravenously) was administered immediately after the patients were transferred into the catheterization laboratory and continued for 6 h. We measured the serum concentrations of creatine kinase isoenzyme MB (CK-MB) before, immediately after, and 6, 12, and 24 h after the procedure, and those of cardiac troponin T (cTnT) 24 h after the procedure. RESULTS There was no significant difference in clinical background between the 2 groups. The nicorandil group showed a significantly lower incidence of CK-MB elevation (>1x upper limit of control range, 20 IU/l) than the control group (8.8% vs 21.8%, p<0.05). The levels of serum CK-MB in the nicorandil group were significantly lower than those in the control group (13.4+/-5.7 vs 16.5+/-9.7 IU/l, p<0.01). Similarly, the nicorandil group showed a significantly lower incidence of cTnT elevation [>1x (0.1 ng/ml) or >2x (0.2 ng/ml)] upper limit of control range than the control group (14.3% vs 26.7%, p<0.05, or 7.7% vs 17.8%, p<0.05). Serum cTnT levels were also significantly lower in the nicorandil group than in the control group (0.05+/-0.10 vs 0.15+/-0.36 ng/ml, p<0.05). CONCLUSIONS The results demonstrated that nicorandil reduces minor cardiac marker elevation after coronary stenting.

Abstract
AIMS Beta-blockers (BBs) have been shown to improve survival and reduce the risk of re-infarction in patients following myocardial infarction. There are conflicting data about the effects of BB therapy on cardiac biomarkers after percutaneous coronary interventions (PCIs). The aim of the study was to investigate the effects of BB use on cardiac troponin-I (cTnI) levels in patients who had undergone elective PCI. METHODS AND RESULTS In this prospective study, 287 patients with coronary artery disease were included. Patients were randomized either to BB or control groups prior to the intervention. Blood samples for cTnI were obtained before and at 6, 24, and 36 h after the procedure. Of the 287 patients included, 143 received metoprolol succinate 100 mg/day, and 144 received no BB and served as the control group. Baseline clinical characteristics of both groups, except for history of coronary artery bypass graft surgery, were similar. We observed no significant difference in the elevation of cTnI levels between the two groups after PCI (BB group, 17 patients, 11.9%; control group, 10 patients, 6.9%; P=0.2). CONCLUSION Metoprolol succinate therapy seems to have no cardioprotective effect in limiting troponin-I rise after PCI.

Preoperative Statin Therapy and Troponin T Predict Early Complications of Coronary Artery Surgery. Ann Thorac Surg 2006; 81:78-83.

Abstract
BACKGROUND Pretreatment with statins reduces early ischemic events after percutaneous coronary interventions, primarily in patients with a high level of inflammation markers. We sought to examine the association between preoperative statin therapy, systemic inflammation, and myocardial ischemia with the occurrence of early cardiac complications after coronary artery bypass grafting surgery. METHODS One hundred forty-one consecutive patients who underwent coronary artery bypass grafting surgery from two university tertiary hospitals were stratified according to their preoperative status of statin therapy (87 treated and 54 nontreated). Preoperative blood samples were collected for measurement of lipid parameters, C-reactive protein, interleukin-6, and troponin T. The evaluated primary endpoint was a composite of death and myocardial infarction at 30 days. RESULTS Patients undergoing preoperative statin therapy showed a reduced incidence of death (2.3% versus 13.0%, p = 0.012), myocardial infarction (5.7% versus 18.5%, p = 0.017), and primary combined endpoint (8.0% versus 22.2%, p = 0.017). In the multivariate model, preoperative troponin T greater than 0.01 ng/mL (odds ratio 6.85, p = 0.001) and nonstatin therapy (odds ratio 4.2, p = 0.01) predicted a higher risk of primary endpoint. Statins showed a significant interaction with troponin T status and benefited primarily those patients with positive troponin T. Among 19 patients with troponin T greater than 0.01 ng/mL, the primary endpoint occurred in all 6 nonstatin-treated patients, but it occurred in only 1 of 13 statin-treated patients (p < 0.001). Neither C-reactive protein nor interleukin-6 predicted early complications, nor did they interact with statin therapy (p = not significant). CONCLUSIONS Preoperative statin therapy reduces early complications and offers additional protection in patients with positive troponin T status, regardless of inflammatory markers.

Abstract
During the past three decades, percutaneous coronary intervention has become one of the cardinal treatment strategies for stenotic coronary artery disease. Technical advances, including the introduction of new devices such as stents, have expanded the interventional capabilities of balloon angioplasty. At the same time, there has been a decline in the rate of major adverse cardiac events, including Q-wave acute myocardial infarction, emergency coronary artery bypass grafting, and cardiac death. Despite these advances, the incidence of post-procedural cardiac marker elevation has not substantially decreased since the first serial assessment 20 years ago. As of now, these post-procedural cardiac marker elevations are considered to represent peri-procedural myocardial injury (PMI) with worse long-term outcome potential. Recent progress has been made for the identification of two main PMI patterns, one near the intervention site (proximal type, PMI type I) and one in the distal perfusion territory of the treated coronary artery (distal type, PMI type II) as well as for preventive strategies. Integrating these new developments into the wealth of clinical information on this topic, this review aims at giving a current perspective on the entity of PMI.

Abstract
The British Cardiac Society commissioned this report to help address inconsistencies in the terminology for acute coronary syndromes and wide variations in the threshold for the diagnosis of myocardial infarction (MI) depending on the assay performed, the precision, and the sensitivity. In addition, several publications have highlighted potential problems with the application of the European Society of Cardiology(ESC)/American College of Cardiology (ACC) consensus document published in 2000. A revision process has been initiated under the guidance of the ESC, the ACC, and the American Heart Association (AHA). The purpose of this report is to help inform the next revision of the ESC/ACC/AHA guidelines for the diagnosis of MI.

Abstract
The predictors of troponin release after percutaneous coronary intervention were prospectively assessed in 405 consecutive patients. Troponin release occurred frequently (27%) and was associated with complications during the procedure, including sapheneous vein graft interventions, multistent use, glycoprotein IIb/IIIa use, and a history of hypercholesterolemia.
