Abstract
Objective This study examined the ability of a combination of biomarkers, including N-terminal pro-B-type natriuretic peptide (N-BNP) and high-sensitivity C-reactive protein (hs-CRP), to better predict mortality than the Global Registry of Acute Coronary Events (GRACE) score in acute myocardial infarction (AMI) patients who received primary percutaneous coronary intervention (PPCI). Methods The in-hospital mortality in 754 all-comer patients with AMI who underwent successful PPCI over 8 years was examined. A receiver operating characteristic (ROC) analysis was performed to determine the in-hospital mortality in a single center. A logistic regression analysis was used to compare the predictive accuracy of the GRACE score and biomarkers. The incremental predictive value of those biomarkers beyond the GRACE score was also examined. Results The mean age was 66±13 years old, and 609 patients with ST-elevated AMI (80.8%) were included. The in-hospital mortality was 6.8%. The GRACE score (in-hospital survivor/non-survivor: 106±33/161±32; p<0.05,) and N-BNP (in-hospital survivor/non-survivor: 2,458±7,058/8,880±1,1331 pg/mL; p<0.05) were significantly lower in survivors than in non-survivors. The area under the ROC curve (AUC) of in-hospital mortality of the GRACE score was significantly higher than that of the dual-biomarker combination (0.868/0.720; p<0.05). The AUC of the combination of the GRACE score and dual-biomarkers was not significantly higher than that of the GRACE score alone (0.870/0.868; p=0.747). Conclusion The measurement of representative cardiovascular biomarkers did not provide any additional benefit for mortality prediction beyond the GRACE score in AMI patients who received PPCI.

Abstract
Systemic vascular inflammation plays multiple maladaptive roles which contribute to the progression and destabilization of atherosclerotic cardiovascular disease (ASCVD). These roles include: (i) driving atheroprogression in the clinically stable phase of disease; (ii) inciting atheroma destabilization and precipitating acute coronary syndromes (ACS); and (iii) responding to cardiomyocyte necrosis in myocardial infarction (MI). Despite an evolving understanding of these biologic processes, successful clinical translation into effective therapies has proven challenging. Realizing the promise of targeting inflammation in the prevention and treatment of ASCVD will likely require more individualized approaches, as the degree of inflammation differs among cardiovascular patients. A large body of evidence has accumulated supporting the use of high-sensitivity C-reactive protein (hsCRP) as a clinical measure of inflammation. Appreciating the mechanistic diversity of ACS triggers and the kinetics of hsCRP in MI may resolve purported inconsistencies from prior observational studies. Future clinical trial designs incorporating hsCRP may hold promise to enable individualized approaches. The aim of this Clinical Review is to summarize the current understanding of how inflammation contributes to ASCVD progression, destabilization, and adverse clinical outcomes. We offer forward-looking perspective on what next steps may enable successful clinical translation into effective therapeutic approaches-enabling targeting the right patients with the right therapy at the right time-on the road to more individualized ASCVD care.

Abstract
Successful risk stratification is necessary for optimum management of patients after acute coronary syndrome (ACS). The aim of the study was to evaluate the role of novel biochemical markers in the prediction of adverse cardiovascular events in stable patients several years after ACS.The study group was randomly selected from all ACS patients treated with reperfusion therapy between 2002 and 2003 at 1st Department of Cardiology, Medical University of Warsaw, Poland. All patients were readmitted to hospital between 2010 and 2011 for clinical and biochemical cardiovascular risk factors assessment and were prospectively observed for 30-months follow-up. The primary endpoint was all-cause death or hospital readmissions due to a cardiovascular condition at 30 months. The secondary endpoint was a composite of all-cause death or hospitalization-related noncardiovascular condition during the follow-up.The study population consisted of 146 patients (mean age 66.6 ± 9.8 years; 60 female). The primary and secondary endpoints occurred in 49 and 65 patients, respectively. Univariate analysis demonstrated that out of 17 analyzed biomarkers only high-sensitive C-reactive protein (hsCRP), Soluble Fms-Like Tyrosine kinase-1 (sFlt-1), and endothelin-1 (ET-1) were significantly associated with primary end-point and N-Terminal pro-B-type natriuretic peptide (NT-proBNP), hsCRP, ET-1, sFlt-1, and procalcitonin (PCT)-with secondary end-point. Multivariate analysis demonstrated that concentration of sFlt-1 was the only independent factor associated with primary end-point (P = .007 and P = .025, respectively), whereas NT-proBNP and hsCRP levels were only associated with secondary end-point (P = .004 and P = .001, respectively).sFlt-1, NT-proBNP, and hsCRP are associated with adverse outcomes in stable patients several years after ACS and may emerge as useful clinical biomarkers to enhance stratify patient's risk.

Abstract
BACKGROUND Thrombolytic therapy is recommended for patients with acute ST-segment elevation myo- cardial infarction (STEMI) who cannot undergo primary percutaneous coronary intervention within the first 120 min. The aim of this study was to demonstrate the value of CHA2DS2-VASc and CHA2DS2- -VASc-HS scores in predicting failed reperfusion in STEMI patients treated with thrombolytic therapy. METHODS A total of 537 consecutive patients were enrolled in the study; 139 had failed thrombolysis while the remaining 398 fulfilled the criteria for successful thrombolysis. Thrombolysis failure was defined with the lack of symptom relief, < 50% ST resolution-related electrocardiography within 90 min from initiation of the thrombolytic therapy, presence of hemodynamic or electrical instability or in-hospital mortality. CHA2DS2-VASc and CHA2DS2-VASc-HS scores, which incorporate hyperlipi- demia, smoking, switches between female and male gender, were previously shown to be markers of the severity of coronary artery disease (CAD). RESULTS History of hypertension, diabetes mellitus, hyperlipidemia, heart failure, smoking, and CAD were significantly common in failed reperfusion patients (for all; p < 0.05). For prediction of failed rep- erfusion, the cut-off value of CHA2DS2-VASc score was ≥ 2 with a sensitivity of 80.90% and a specificity of 41.01% (area under curve [AUC] 0.660; 95% confidence interval [CI] 0.618-0.700; p < 0.001) and the cut-off value of CHA2DS2-VASc-HS score was ≥ 3 with a sensitivity of 76.13% and a specificity of 67.63% (AUC 0.764; 95% CI 0.725-0.799; p < 0.001). The CHA2DS2-VASc-HS score was found to be statistically and significantly better than CHA2DS2-VASc score to predict failed reperfusion (p < 0.001). CONCLUSIONS The findings suggest that the CHA2DS2-VASc and especially CHA2DS2-VASc-HS scores could be considered as predictors of risk of failed reperfusion in STEMI patients.

Abstract
It has been reported that increased levels of C-reactive protein are related to adverse long-term prognosis in the setting of ST-segment elevation acute myocardial infarction (MI). In previous studies, the timing of C-reactive protein determination has varied widely. In the present study, serial high-sensitivity C-reactive protein (hsCRP) measurements were performed to investigate if any of the measurements is superior regarding long-term prognosis. A total of 861 consecutive patients admitted for ST-segment elevation MI and treated with intravenous thrombolysis within the first 6 hours from the index pain were included. HsCRP levels were determined at presentation and at 24, 48, and 72 hours. The median follow-up time was 3.5 years. New nonfatal MI and cardiac death were the study end points. By the end of follow-up, cardiac death was observed in 22.4% and nonfatal MI in 16.1% of the patients. HsCRP levels were found to be increasing during the first 72 hours. Multivariate Cox regression analysis demonstrated that hsCRP levels at presentation were an independent predictor of the 2 end points (relative risk [RR] 2.8, p = 0.002, and RR 2.1, p = 0.03, for MI and cardiac death, respectively), while hsCRP levels at 24 hours did not yield statistically significant results (RR 1.4, p = 0.40, and RR 1.1, p = 0.80, for MI and cardiac death, respectively). The corresponding RRs at 48 hours were 1.2 (p = 0.5) for MI and 3.2 (p = 0.007) for cardiac death and at 72 hours were 1.6 (p = 0.30) for MI and 3.9 (p <0.001) for cardiac death. In conclusion, hsCRP levels at presentation represent an independent predictor for fatal and nonfatal events during long-term follow-up. HsCRP levels at 48 and 72 hours, which are close to peak hsCRP levels, independently predict only cardiac death.

Abstract
Cardiac biomarkers assist in the diagnosis of and risk stratification in acute coronary syndromes. In ST-elevation myocardial infarction (STEMI), rapid diagnosis and initiation of reperfusion via primary percutaneous coronary intervention or fibrinolysis is often based on the clinical history and presenting ECG, but measurement of biomarkers in the early and/or late phases of STEMI may allow the selection of patients who are at increased or decreased risk of subsequent complications. Although the measurement of only three biomarkers (troponin, natriuretic peptides and C-reactive protein) are currently included in practice guidelines, more than 20 other novel cardiac biomarkers have been proposed to provide improved risk stratification after a STEMI.

Abstract
Background and Objectives The prognostic value of biochemical markers and the resolution of ST-segment elevation on electrocardiogram are well established. However, how a combination of these two tools affects the evaluation of risk stratification has not yet been evaluated. Subjects and Methods Between January 2006 and June 2008, 178 consecutive patients treated with primary percutaneous coronary interventions after ST-segment elevation myocardial infarctions (STEMI) were analyzed at two coronary care units. Patients were divided into the following three groups according to ST-segment resolution: complete (≥70% depression of the elevated ST-segment, n=63), partial (30% to 70%, n=90), and incomplete (<30%, n=25). Demographic data, including history, electrocardiography, biochemical markers, initial ejection fraction, and angiographic findings were also evaluated. Results There were 7 deaths, 3 repeated myocardial infarctions, and 17 readmissions for worsening heart failure during six months of follow-up. In a multivariate analysis to predict clinical outcomes, ejection fraction {hazard ratio (HR): 0.83 (0.76-0.91), p<0.01}, high-sensitivity C-reactive protein {HR: 1.15 (1.05-1.26), p<0.05}, and the degree of ST-segment resolution {HR: 0.96 (0.93-0.09), p<0.05} were independently associated with clinical outcomes. According to the Cox-proportional hazards model, the addition of ST-segment resolution markedly improved the prognostic utility of the model containing biochemical markers and ejection fraction. Conclusion Assessment of biomarkers upon admission and ST-segment resolution are strong predictors of clinical outcomes. The combination of these data provides additive information about prognosis at an early point in the disease progression and further improves risk stratification for STEMI.

Abstract
BACKGROUND C-reactive protein (CRP) is an established prognostic marker in the setting of acute coronary syndromes. Recently, albumin excretion rate also has been found to be associated with adverse outcomes in this clinical setting. Our aim was to compare the prognostic power of CRP and albumin excretion rate for long-term mortality following acute myocardial infarction (AMI). HYPOTHESIS To determine whether albumin excretion rate is a better predictor of long-term outcome than CRP in post-AMI patients. METHODS We prospectively studied 220 unselected patients with definite AMI (median [interquartile] age 67 [60-74] y, female 26%, heart failure 39%). CRP and albumin-to-creatinine ratio (ACR) were measured on day 1, day 3, and day 7 after admission in 24-hour urine samples. Follow-up duration was 10 years for all patients. RESULTS At survival analysis, both CRP and ACR were associated with increased risk of 10-year all-cause mortality, also after adjusting for age, hypertension, diabetes mellitus, prehospital time delay, creatine kinase-MB isoenzyme peak, heart failure, and creatinine clearance. CRP and ACR were associated with nonsudden cardiovascular (non-SCV) mortality but not with sudden death (SD) or noncardiovascular (non-CV) death. CRP was not associated with long-term mortality, while ACR was independently associated with outcome both in short- and long-term analyses. At C-statistic analysis, CRP did not improve the baseline prediction model for all-cause mortality, while it did for short-term non-SCV mortality. ACR improved all-cause and non-SCV mortality prediction, both in the short and long term. CONCLUSIONS ACR was a better predictor of long-term mortality after AMI than CRP.

Abstract
Aldehyde dehydrogenase-2 (ALDH2) is a key enzyme of alcohol metabolism, catalyzing the conversion of aldehyde to acetic acid. The G-to-A polymorphism in exon 12 of the ALDH2 gene, which causes Glu-to-Lys substitution at codon 504, has been shown to be an independent risk factor for acute myocardial infarction (AMI). We investigated the possible role of the G-to-A polymorphism in the severity of the myocardial damage in the early phase of AMI by measuring plasma levels of inflammatory markers, including high-sensitivity C-reactive protein (hs-CRP). A total of 226 Han Chinese patients with AMI were divided into two groups: subjects without A allele (GG, n = 144) and subjects with A allele (GA and AA, n = 82), and the blood samples were collected within 12 hours after the onset of AMI. The results displayed that high-density lipoprotein cholesterol (HDL-C) was higher in GG group than that in GA and AA group (p < 0.05). The body mass index (BMI) and the concentration of hs-CRP were lower in GG group than that in GA and AA group (p < 0.05). Multivariate logistic regression analysis showed that subjects with the A allele were at an increased risk for the high level of hs-CRP (> 3 mg/L) compared with those with GG genotype (OR = 4.908, 95% CI = 1.57 approximately 20.98). Thus, the A allele in ALDH2 gene is associated with the elevated plasma levels of hs-CRP after the onset of AMI, suggesting a higher susceptibility of the myocardium to ischemic injuries.

Abstract
The present study investigated the association between C-reactive protein (CRP) on admission independently and in combination with troponin and short-term prognosis in an unselected sample of patients with acute myocardial infarction (AMI) from the community. The study population consisted of 1,646 patients aged 25 to 74 years who were consecutively hospitalized with AMI within 12 hours after symptom onset. They were divided into the 2 groups of CRP positive (n = 919) or CRP negative (n = 727) with respect to admission CRP (cutoff < or =0.3 mg/dl). CRP-positive patients had significantly more in-hospital complications and a higher 28-day case-fatality rate (9.6% vs 3.4%; p <0.0001). Troponin at admission (n = 1,419) also correlated with 28-day case-fatality rate (troponin-negative 3.4% vs troponin-positive patients 8.0%; p <0.002). Multivariable analysis showed that both troponin positivity and CRP positivity were associated with a 2-fold (adjusted odds ratio 1.99, 95% confidence interval 1.15 to 3.44; adjusted odds ratio 2.05, 95% confidence interval 1.09 to 3.84, respectively) increased risk of dying within 28 days after the acute event for all patients with AMI. Stratifying by AMI type showed that in patients with ST-elevation myocardial infarction (STEMI), troponin positivity, but not CRP positivity, independently predicted 28-day case fatality. In patients with non-STEMI, CRP positivity, but not troponin positivity, predicted outcome. In conclusion, admission CRP was a powerful parameter for risk stratification of patients with AMI. Stratification by AMI type and troponin showed that CRP was a better short-term risk predictor for patients with non-STEMI, and troponin was, for patients with STEMI.

Abstract
BACKGROUND Acute myocardial infarction (AMI) due to left main coronary artery disease is associated with significantly elevated morbidity and mortality. The aim of this study was to identify the predictors of in-hospital death from left main AMI complicated by cardiogenic shock. METHODS Clinical record review identified a total of 25 cases of left main AMI with cardiogenic shock. Patients' background characteristics, laboratory data, and angiographic findings were analyzed according to the in-hospital mortality. RESULTS In this patient subset, in-hospital mortality (60%) was associated with a history of hypertension (p=0.02) and a higher heart rate (p=0.02). Furthermore, in-hospital mortality was also associated with a complete right bundle branch block (CRBBB) pattern in the admission ECG (p=0.01) and low HCO(3)(-) (p=0.0004). In stepwise logistic regression analysis, a CRBBB pattern (OR 48.59, 95% CI 1.34-1768.10, p=0.03) and low HCO(3)(-) (OR 0.62, 95% CI 0.40-0.94, p=0.02) were found to be independent predictors of mortality. CONCLUSIONS Left main AMI with cardiogenic shock was associated with high in-hospital mortality. A CRBBB pattern in the ECG on admission and a low HCO(3)(-) concentration were significant independent predictors of in-hospital death.

Abstract
Diagnosis of cardiac ischemia in patients coming to emergency departments (ED) with symptoms of acute chest pain is often difficult. Many markers are sensitive and specific for the detection of myocardial necrosis but may not rise during reversible myocardial ischemia. Ischemia-modified albumin (IMA) has recently been shown to be a sensitive and early biochemical marker of ischemia. The variation laws were observed by measuring IMA and C-reactive protein (CRP) of 113 patients in ED within 12 hr after onset of chest pain. In the observation, blood was taken for IMA and CRP. Patients underwent standardized triage, diagnostic procedures, and treatment. Results of IMA and CRP were correlated with final diagnoses of nonischemic chest pain (NICP) and acute coronary syndrome (ACS). There were obvious distinction of IMA and CRP levels between the NICP and ACS groups. Receiver operator characteristic (ROC) curve analysis was used to determine the optimal cutoff of this assay for identifying individuals with ACS patients from NICP. The area under the curves of IMA is 0.948. The sensitivity and specificity of albumin cobalt binding (ACB) at a cutoff value of 70.0 units/mL were 94.4% and 82.6%, respectively. The area under the curves of CRP is 0.746. Sensitivity and specificity of CRP at a cutoff value of 3.16 mg/L were 70.0% and 73.9%, respectively. Negative predictive value (NPV) of IMA and CRP for ischemia origin was 79.2% and 38.6%, respectively. IMA may make an early diagnosis of acute coronary ischemia, and will improve the early diagnostic sensitivity and specificity of ACS.

Comparison of usefulness of C-reactive protein versus white blood cell count to predict outcome after primary percutaneous coronary intervention for ST elevation myocardial infarction. Am J Cardiol 2008; 101:446-51. [PMID: 18312755 DOI: 10.1016/j.amjcard.2007.09.088] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2007] [Revised: 09/24/2007] [Accepted: 09/24/2007] [Indexed: 12/19/2022]
Abstract
White blood cell (WBC) count and high-sensitive C-reactive protein (hs-CRP) are both used as markers of inflammation and prognosis after an ST elevation myocardial infarction (STEMI), but it is unknown whether they have independent prognostic value. We investigated the association and independent prognostic importance of WBC and hs-CRP after STEMI. In this subanalysis of the On-TIME trial, in 490 of 507 (97%) patients, either WBC count or CRP, and in 362 (71%) patients, both WBC count and CRP, were measured on admission before primary percutaneous coronary intervention. There was no significant correlation between WBC count and CRP (R = 0.080). Higher levels of CRP were associated with a reinfarction or death within 1 year (mean hs-CRP 14.2 +/- 20.4 vs 6.1 +/- 14.2, p = 0.006), but CRP was not associated with enzymatic infarct size (lactate dehydrogenase, LDHQ48) or left ventricular ejection fraction. A higher baseline WBC count was associated with larger LDHQ48 and lower left ventricular ejection fraction but not with 1-year reinfarction or death. In conclusion, although both WBC count and CRP are markers of inflammation and predictors of outcome after STEMI, we did not find a correlation between baseline WBC count and CRP levels in patients treated with primary percutaneous coronary intervention for STEMI. The mechanisms by which WBC counts predict outcome were related to myocardial infarct size whereas CRP were not.

Abstract
We evaluated whether high circulating levels of serum amyloid A (SAA), fibrinogen, interleukin-6 (IL-6) or leukocytes count (LC), can provide any additional predictive value over that provided by hs C-reactive protein (hs-CRP) for the incidence of 5-year cardiovascular mortality, in 458 and 476 consecutive patients with ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation acute coronary syndromes (NSTE-ACS), respectively. By 5 years the incidence of cardiovascular mortality was 37.3% and 35.5% in patients with STEMI and NSTE-ACS, respectively. Each of the study inflammatory biomarkers conferred independent to clinical risk predictors (and to cardiac troponin I) long-term prognostic information (all p<0.05), but only LC provided additional predictive value over that provided by hs-CRP, in either cohort (p<0.05). By multivariate Cox regression analysis, hs-CRP (p<0.001 for both cohorts) and LC (p=0.009 and p<0.001 for STEMI and NSTE-ACS, respectively) were the only inflammatory biomarkers independently associated with the incidence of 5-year cardiovascular mortality. According to the present results high circulating levels of LC but not of SAA, fibrinogen or IL-6 can provide additional long-term predictive value over that provided by hs-CRP in patients with acute coronary syndromes.

Abstract
The aim of this study was to investigate the predictive value of an oxidative stress, C-reactive protein (CRP) and N-terminal probrain natriuretic peptide (NT-proBNP) biomarkers in acute myocardial infarction (AMI). The study population contained 100 patients with AMI and 40 healthy subjects. Malondialdehyde (MDA) was measured as thiobarbituric acid reactive substances. Total antioxidant status (TAC) was assayed with colorimetric method. CRP and NT-proBNP was quantitated by immunoassay. MDA, CRP and NT-proBNP levels were found significantly high in patients with AMI as compared to healthy controls (p<0.01). Patients were divided into six groups based on the presence of disease history before AMI. In patients with non-disease before AMI. MDA, CRP and NT-proBNP levels were lowest among the patient groups. MDA levels in patients with hyperlipidemia/ diabetes/renal disease were higher than the other groups. TAC levels in patients with hypertension were lower than as compared to healthy controls (p<0.05). CRP levels in hypertension + hyperlipidemia patients and NT-proBNP levels in cardiovascular + hypertension patients were found high as compared to other patient groups. It is concluded that serum levels of MDA, CRP and NT-proBNP were significantly increased in patients with AMI and these markers were strongly predictive in AMI.

Abstract
OBJECTIVES To evaluate, using continuous 12-lead ECG ST-segment monitoring, the role of circulating levels of both cardiac troponin I (cTnI) and high-sensitivity C reactive protein (hs-CRP), on presentation, in the prediction of intravenous thrombolysis outcome in patients with ST-segment elevation myocardial infarction (STEMI). DESIGN AND SETTING Prospective observational study in a tertiary referral centre. PATIENTS 786 consecutive patients with STEMI, who received intravenous thrombolysis in the first 6 h from index pain. MAIN OUTCOME MEASURES The incidence of failed thrombolysis and of cardiac death by 30 days. Failed thrombolysis was defined as the absence of abrupt and sustained > or =50% ST-segment recovery in the first 90 min after the initiation of intravenous thrombolysis. RESULTS The incidence of failed thrombolysis and 30-day cardiac death was 57.4% and 11.8%, respectively. By multivariate logistic regression analysis according to tertiles of both cTnI (RR, 1.5; 95% CI 1.1 to 1.8, p = 0.004 for highest vs middle third; 2.2, 1.9 to 3.5, p<0.001 for highest vs lowest third; 1.5, 1.2 to 1.8, p = 0.001 for middle vs lowest third) and hs-CRP (RR, 2.0, 95% CI, 1.6 to 2.2; p<0.001 for highest vs middle third; 2.6, 2.1 to 3.5, p<0.001 for highest vs lowest third; 1.3, 1.2 to 1.7, p = 0.02 for middle vs lowest third), were independently associated with failed thrombolysis. Moreover, by multivariate Cox regression analysis according to tertiles of both cTnI (HR 1.2, 95% CI 1.1 to 1.8, p = 0.03 for highest vs middle third; 1.5, 1.2 to 2.2, p = 0.004 for highest vs lowest third; 1.1, 0.6 to 1.4, p = 0.6 for middle vs lowest third) and hs-CRP (HR1.2, 95% CI 1.1 to 1.6, p = 0.04 for highest vs middle third; 1.7, 1.3 to 2.6, p = 0.001 for highest vs lowest third; 1.1, 0.9 to 2.1, p = 0.1 for middle vs lowest third), were independently related with an increased risk of 30-day cardiac death. CONCLUSIONS High circulating levels of both cTnI and hs-CRP are related with an independent increased risk of intravenous thrombolysis failure and 30-day cardiac death in patients who received intravenous thrombolysis in the first 6 h of STEMI.

Abstract
Increased levels of C-reactive protein (CRP) could be detected in subjects with acute coronary syndrome (ACS). Several factors, atherosclerosis, coronary flow impairment, myocardial necrosis, each one acting during a different, earlier or later, phase of ACS, are supposed to be involved in CRP release in case of ACS. Role and relevance of each factor, not mutually exclusive, still need to be comparatively evaluated but a cooperative synergism could be presumably hypothesized.

Abstract
BACKGROUND The aim of this study was to evaluate whether risk for postoperative atrial fibrillation in women is related to preexisting inflammation as detected by plasma C-reactive protein (CRP) concentrations. We further sought to assess the importance of atrial fibrillation for outcome after cardiac surgery in women. METHODS The CRP was measured before coronary artery bypass grafting and (or) valvular surgery using cardiopulmonary bypass in 141 women. Univariate and multivariate analyses were used to evaluate for differences in CRP levels between women with and without atrial fibrillation, and to assess for the importance of the arrhythmia and postoperative outcomes. RESULTS Atrial fibrillation developed in 46 (33%) women. Neither CRP concentrations (median +/- standard error, 13.3 +/- 2.5 mg/L vs 11.7 +/- 1.4 mg/L, p = 0.847), nor the frequency of elevated levels (defined as > upper 95% confidence interval or >19.2 mg/L) (19% vs 21%, p = 0.807) differed between women with or without atrial fibrillation. Patient age and previous stroke, but not CRP levels, were independently associated with atrial fibrillation. Women with atrial fibrillation were more likely to have low cardiac output syndrome (p = 0.018), stroke (p = 0.031), longer duration of hospitalization in the intensive care unit (p = 0.012) and on the postoperative (p = 0.0008) ward, and they were more likely to require an extended care facility after surgery (p = 0.046). CONCLUSIONS In contrast to findings from studies that have included mostly men, preoperative CRP concentrations are not associated with risk for atrial fibrillation after cardiac surgery for women. Postoperative atrial fibrillation in women is associated with increased risk for stroke, longer hospitalization, and extended care facility admission.

Abstract
Plasma fibrinogen, C-reactive protein (CRP), and interleukin-6 (IL-6) levels in patients with acute myocardial infarction (AMI) receiving thrombolysis have been related to prognosis. The aim of this study was to investigate the time course of plasma fibrinogen, CRP, and IL-6 levels during the in-hospital phase in patients with AMI receiving thrombolysis, and their relationship to in-hospital and prognosis after 12-months follow-up. In 40 patients presenting with AMI within 6 hours of symptom onset and treated with thrombolysis, plasma fibrinogen, CRP, and IL-6 levels were measured on admission and after 6, 12, 24, 48, and 72 hours; 7 days; and 6 months. Patients with other diseases that can alter fibrinogen, CRP, or IL-6 levels were excluded. Patients had a clinical follow-up at 6 and 12 months, and the following cardiac events were recorded: cardiac death, recurrent angina, recurrent AMI, and heart failure. Plasma fibrinogen concentrations decreased significantly (p <0.01 vs admission levels) at 12 hours (425 +/-94 vs 322 +/-132 mg/dL), started to increase at 24 hours, reached peak value at 72 hours (602 +/-209 mg/dL), remained elevated at 7 days, and were back to admission levels at 6 months (375 +/-79 mg/dL). CRP levels increased significantly at 12 hours (0.73 +/-0.43 vs 0.23 +/-0.11 mg/dL, p <0.01), reached peak value at 72 hours (7.66 +/-3.28 mg/dL), decreased significantly on day 7 (2.32 +/-1.17 mg/dL), and at 6 months were within normal limits (0.49 +/-0.29 mg/dL). IL-6 levels increased significantly at 6 hours (14.03 +/-8.13 vs 6.37 +/-3.88 pg/mL, p <0.05), reached peak value at 24 hours (59.49 +/-23.57 pg/mL), started to decrease at 48 hours, and at 6 months were within normal limits (2.25 +/-1.24 pg/mL). During the in-hospital phase 33 patients had an uneventful course and 7 patients had complications (3 post-AMI angina; 4 heart failure). During the 12-month follow-up period 28 patients had an uneventful course, and 12 patients had complications (1 cardiac death, 5 recurrent angina, 2 recurrent AMI, and 4 heart failure). Regarding the in-hospital prognosis, fibrinogen, CRP, and IL-6 levels were significantly higher (p <0.05) in patients with complications from 48 to 72 hours, from 12 hours until day 7, and from 6 hours until day 7, respectively. During the 12-month follow-up period fibrinogen, CRP, and IL-6 levels were significantly higher in patients with complications (at 48, 24, and 24 hours, respectively) only in the subgroup of patients who had complications within the first 6 months following AMI. Multivariate analysis showed that CRP at 48 hours was the most important factor related to in-hospital prognosis (p = 0.02), and ejection fraction followed by CRP at 24 hours (p = 0.02) to 6-month prognosis (p = 0.018). Fibrinogen, CRP, and IL-6 levels alter in patients with AMI receiving thrombolysis, and are related both to in-hospital and to 6-month follow-up prognosis.

Abstract
This study sought to evaluate the relation between C-reactive protein (CRP) on admission of patients with acute myocardial infarction (AMI) and myocardial perfusion as defined by postintervention angiographic myocardial blush grade (MBG) and their impact on subsequent mortality. The patient population comprised 191 consecutive patients with AMI undergoing PTCA within 12h of symptom onset on a native vessel. Patients were divided based on the CRP level on admission (Rolf Greiner BioChemica, Germany, cutpoint for the assay CRP: 5mg/l) into a group with elevated CRP (>or=5mg/l) and a group with normal CRP. Angiographic myocardial blush grade (MBG) after revascularization of the infarct-related artery was determined to evaluate myocardial reperfusion. Revascularization of the infarct-related artery was successful in 176 (92.6%) patients. The frequency of impaired perfusion (MBG 0-2) was higher in the elevated CRP group than in the normal CRP group (74.5% versus 59.7%, respectively, p=0.046). Elevated CRP on admission was an independent predictor of impaired myocardial perfusion (MBG 0-2, OR 1.92, 95% CI 1.02-4.01, p=0.042) in addition to age >70 years. Elevated CRP (OR 2.64, 95% CI 1.26-5.53, p=0.009) and MBG 0-2 (OR 4.58; 95% 1.73-12.20, p=0.002) were independent predictors of mortality during a 22.4+/-15.3 months follow-up in addition to heart rate on admission >100 beats/min (OR 3.07; 95% CI 1.30-7.25, p=0.009). In sequential Cox models, the predictive power of clinical data and MBG for mortality (model chi-squared 18.3) was strengthened by the inclusion of CRP levels (model chi-squared 24.3). In conclusion, there is a relation between elevated admission CRP and impaired reperfusion in the myocardium subtended to the infarct-related artery. The combination of clinical data, myocardial reperfusion levels after primary angioplasty for AMI and admission CRP increases the predictive value for subsequent survival.

Abstract
OBJECTIVES The objectives of this study were to examine the time course of the inflammatory response in acute coronary syndromes (ACS) and to assess the markers of inflammation and their relation to disease severity. METHODS We prospectively studied 134 patients with ACS who survived for at least 30 months. The patients were divided into four groups: acute myocardial infarction (MI) with (n=54) or without (n=46) ST-segment elevation and unstable angina with (n=14) or without (n=20) increased risk. Plasma levels of C-reactive protein (CRP), interleukin-6 (IL-6), secretory phospholipase A2 group IIA (sPLA2-IIA), and intercellular adhesion molecule-1 (ICAM-1) were measured on days 1 and 4 and after 3 and 30 months. RESULTS The highest levels of CRP and sPLA2-IIA were seen on day 4 but for IL-6 on day 1. These three markers, but not ICAM-1, were significantly related to disease severity, CKMB, and ejection fraction. Patients in Killip class II-IV had higher levels than those in Killip class I. The individual acute-phase responses correlated with marker levels at 3 and 30 months. ICAM-1 correlated with the development of congestive heart failure. CONCLUSIONS In ACS there seems to be an individual predisposition to inflammatory response. Plasma IL-6 is the first marker to rise, while sPLA2-IIA and CRP peak later. All three markers, especially CRP, may discriminate between MI and non-MI. ICAM-1 seems to reflect other aspects of the inflammatory processes than the other markers. The results emphasize the complexity of the inflammatory response in ACS and stress the need for further studies involving multiple markers.

Abstract
OBJECTIVES The purpose of this study was to determine the prognostic value of circulating secretory phospholipase A2 (sPLA2) activity in patients with acute coronary syndromes (ACS). BACKGROUND The plasma level of type IIA sPLA2 is a risk factor for coronary artery disease (CAD) and is associated with adverse outcomes in patients with stable CAD. The prognostic impact of sPLA2 in patients with ACS is unknown. METHODS Secretory phospholipase A2 antigen levels and activity were measured in plasma samples of 446 patients with ACS, obtained at the time of enrollment. RESULTS Baseline sPLA2 activity was associated with the risk of death and myocardial infarction (MI). The unadjusted rate of death and MI increased in a stepwise fashion with increasing tertiles of sPLA2 activity (p < 0.0001). The association remained significant in the subgroup of patients who had MI with ST-segment elevation (p = 0.014) and the subgroup of patients who had unstable angina or non-ST-segment elevation MI (p < 0.002). After adjustment for clinical and biological variables, the hazard ratios for the combined end point of death or MI in the third tertile of sPLA2 compared with the first and second tertiles was 3.08 (95% confidence interval, 1.37 to 6.91, p = 0.006). CONCLUSIONS A single measurement of plasma sPLA2 activity at the time of enrollment provides strong independent information to predict recurrent events in patients with ACS.

Grade 3 ischemia on admission and absence of prior beta-blockade predict failure of ST resolution following thrombolysis for anterior myocardial infarction. Int J Cardiol 2005; 104:131-7.

Abstract
BACKGROUND ST segment resolution (STR) is a strong predictor of outcome following thrombolysis. If failure of STR could be predicted on admission, better selection of treatment may be possible. Among patients given reperfusion, those with terminal QRS distortion (grade 3 ischemia) have larger infarcts, but the mechanism underlying this association is unclear. Whether grade 3 ischemia on admission can predict STR is unknown. METHODS We studied 180 consecutive patients given thrombolysis for a first anterior acute myocardial infarction (AMI). Multiple variables available on admission were analyzed as predictors of STR at 1, 2, and 24 h and as predictors of the need for rescue percutaneous coronary intervention (PCI). RESULTS Multivariate predictors of failure of STR were: for 1 h: extent of ST elevation (OR: 1.09 [1.01-1.18]); for 2 h: no previous use of beta-blockers (OR: 4.71 [1.56-13.98]) and grade 3 ischemia (OR: 6.77 [3.27-13.95]); for 24 h: previous use of aspirin (OR: 6.70 [1.31-34.01]) and grade 3 ischemia (OR: 29.44 [7.30-118.1]). Grade 3 ischemia had a strong positive predictive value for failure of STR at 1 and 2 h and was the strongest predictor of the need for rescue PCI. CONCLUSIONS Grade 3 ischemia on admission is the strongest independent predictor of failure to achieve myocardial reperfusion after thrombolysis. This association may underlie the larger infarcts associated with grade 3 ischemia. Other predictors of reperfusion failure are the extent of ST segment elevation, prior use of aspirin and no prior use of beta-blockers.

Abstract
BACKGROUND In patients with acute coronary syndrome (ACS), the prevalence of a primary inflammatory pathogenic component of coronary instability, as detectable by elevated C-reactive protein (CRP), varies considerably. The aim of the present study was to assess the prevalence of inflammation in patients with ACS according to the different electrocardiographic (ECG) patterns on admission. METHODS Hundred and thirty-six consecutive patients with the diagnosis of acute myocardial infarction were divided in three groups according to the ECG pattern on admission. Group 1 included 59 patients with ST segment elevation, group 2 included 50 patients with ST depression and/or T wave inversion and group 3 included 27 patients with no ECG changes. CRP was measured on admission in all patients. For the prevalence of inflammation analysis, we used a cutoff value of 3 mg/l. RESULTS CRP was above cutpoint significantly more often in patients with ST depression and/or T wave inversion (44.1% in group 1, 70% in group 2 and 40.7% in group 3; p=0.009). Patients with similar ECG pattern and CRP levels above the cutpoint presented a poorer outcome (coronary death, myocardial infarction and recurrence of instability) at one-year follow-up: 54 versus 27% for group 1, 74 versus 27% for group 2 and 45 versus 31% for group 3. CONCLUSIONS Patients with ST depression and/or T wave inversion on admission exhibit a higher prevalence of elevated CRP than those with ST elevation or no ECG changes, suggesting an important heterogeneity of the role of inflammatory triggers of the clinical syndromes of coronary instability.

Abstract
The aim of the present study was to evaluate whether an elevated plasma C-reactive protein (CRP) level provides any additional prognostic information to the validated Thrombolysis In Myocardial Infarction (TIMI) risk score in patients with acute coronary syndromes. For this purpose, 1,846 consecutive patients with either acute ST-segment elevation myocardial infarction (STEMI; 861 patients) or non-ST-segment elevation acute coronary syndrome (NSTEACS; 985 patients) were included. The incidence of 30-day death and 14-day composite of death, myocardial infarction (or repeat myocardial infarction) and recurrent ischemia was the prespecified primary end point in the STEMI and NSTEACS cohorts, respectively. The incidence of the primary end point was 9.8% and 23.6% in the STEMI and NSTEACS cohorts, respectively. A significantly increased risk of the primary end point was present with an increase in the STEMI and NSTEACS TIMI risk score (p(trend) < 0.001 for the 2 groups). A plasma CRP value of > or = 5 and > or = 3 mg/L (defined by receiver-operating characteristic analysis) was associated with a significantly increased risk of the primary end point in the STEMI and NSTEACS cohorts, respectively (p < 0.001 for the 2 cohorts), and it was true throughout the subgroups of STEMI and NSTEACS TIMI risk scores. In conclusion, an elevated plasma CRP level appears to be a marker that adds prognostic information to the validated STEMI and NSTEACS TIMI risk score. The plasma CRP and TIMI risk score may be used together for enhanced risk stratification in the setting of acute coronary syndromes.

Abstract
INTRODUCTION Thrombolytic therapy fails to achieve reperfusion in almost a third of patients with acute myocardial infarction. Thrombin activatable fibrinolysis inhibitor (TAFI) and soluble CD40 ligand (sCD40L) are novel endogenous fibrinolytic and atherothrombotic factors that determine clot stability. We investigated whether admission plasma thrombin activatable fibrinolysis inhibitor (TAFI) and soluble CD40 ligand (sCD40L) concentrations predicted reperfusion following thrombolytic therapy in patients with acute myocardial infarction. MATERIALS AND METHODS Prior to administration of thrombolytic therapy, venous blood was collected from 110 patients presenting with acute ST segment elevation myocardial infarction and plasma assayed for tissue plasminogen activator (t-PA) antigen and activity, plasminogen activator inhibitor type-1 antigen (PAI-1), TAFI antigen and activity, C-reactive protein (CRP) and sCD40L concentrations. Reperfusion was determined using continuous ST segment monitoring. RESULTS Reperfusion occurred in 77 (70%) patients with a mean treatment to reperfusion time of 83 +/- 46 min. Peak creatine kinase was significantly lower in patients who reperfused (1578 +/- 1199 versus 2200 +/- 1744 U/L; P < 0.05) and correlated with time to reperfusion (r = 0.44 [95% CI: 0.23 - 0.61], P = 0.0001). There was a modest correlation between plasma TAFI antigen and activity (r = 0.3 [95% CI: 0.04 - 0.53]; P < 0.05). There were no significant associations between coronary reperfusion and plasma concentrations of t-PA, PAI-1, TAFI, CRP or sCD40L. CONCLUSIONS Systemic plasma TAFI, sCD40L and CRP concentrations do not predict reperfusion in patients receiving thrombolytic therapy for acute ST elevation myocardial infarction.

Abstract
BACKGROUND C-reactive protein (CRP) plasmatic levels increase in patients with acute coronary syndromes (ACS). Correlations between CRP levels, myocardial functional damage and cardiomyocyte lysis remain to be defined. METHODS 192 consecutive patients with acute coronary syndromes (64.97 +/- 11.08 mean age, 71.35% male gender) were included in the study; 138 patients (71.87%) were discharged with an acute myocardial infarction (AMI) diagnosis (28 with non Q-wave AMI) and 54 with an unstable angina (UA) diagnosis (28.13%). In all patients CRP, CK, LDH, CK-MB and troponin I plasmatic concentrations were evaluated every 6 h for 48 h and every 24 h for the following 2 days from the onset of symptoms. Ejection fraction was estimated by bidimensional echocardiography and extension of myocardial lysis by cardiac enzymes plasmatic release. 92 patients (67 with AMI, 25 with UA) underwent coronary-angiography. Incidence of adverse cardiac events was recorded in a 6 months follow up. RESULTS Mean CRP levels in Q-wave MI showed a statistically significant increase in the different blood samples with baseline. Mean CRP levels of the three groups were not statistically different at baseline and after 6, 12, and 18 h. Q-wave AMI CRP levels showed a statistically significant difference as against non Q-wave AMI at 36 (p < 0.05), 48 (p < 0.05) and 72 h (p < 0.05) and UA at 24 (p < 0.01), 30 (p < 0.01), 48 (p < 0.0001), 72 (p = 0.0001) and 96 h (p = 0.0003); non Q-wave AMI CPR levels showed a statistically significant difference as against UA at 48 h (p < 0.01). CRP peak mean levels were significantly different when comparing Q-wave AMI patients with UA patients (8.21 +/- 7.85 vs. 2.75 +/- 3.33 mg/dl, p < 0.001). In patients with Q-wave AMI there was a correlation between CRP peak concentrations and CK (r = 0.264, p = 0.008) and LDH (r = 0.32, p = 0.001), while correlation with CK-MB peak concentrations was not statistically significant (r = 0.196, p = 0.051). In the same patient group, there was also a correlation between CRP plasmatic concentrations and troponin I plasmatic concentrations from the 30th to 96th h after the onset of symptoms (r = 0.38-0.53, p < 0.05). No correlation was found between CRP levels and ejection fraction and angio-coronarography findings (number of stenotic vessels, culprit lesions, ruptured plaques). Peak CRP levels were associated in a 6 months follow up with an increased incidence of major adverse cardiac events (MACEs) in patients with Q-wave AMI (HR 1.1649, 95% C.I. 1.0197-1.3307, p < 0.05). CONCLUSIONS CRP plasmatic concentrations showed a different release curve in patients with Q-wave AMI in comparison with patients with non Q-wave AMI and with patients with UA. CRP peak concentrations did not correlate with ejection fraction and angiographic findings, but correlate with incidence of MACE. The increase in CRP levels during Q-wave MI seems to be linked to the extension of myocardial damage rather than pre-existing inflammation.

Abstract
BACKGROUND Diffuse coronary vascular inflammation is associated with acute coronary syndromes. However, it is unknown whether inflammation also occurs within the myocardium. Therefore, this study was aimed at assessing the presence of activated cells in unaffected remote myocardium of patients with acute myocardial infarction (AMI), in comparison to the peri-infarct region from the same cases, and in comparison to myocardial specimens from control hearts. METHODS AND RESULTS Sixteen patients dying 1 to 12 weeks after AMI and 16 control subjects were selected at autopsy. Myocardial specimens were taken at remote unaffected viable regions and at peri-infarct regions in cases with AMI. Confocal microscopy was performed to measure the number of activated cells (DR+), T-lymphocytes (CD3+), and activated T-lymphocytes (CD3+/DR+). Activated cells and activated T-lymphocytes were found in remote unaffected regions in 11 of 16 cases (69%), in peri-infarct zone in all cases (100%), and in none of the control hearts (0%, P<0.001 versus others). A greater myocardial inflammatory burden in remote regions but not in peri-infarct regions was associated with persistent infarct-related artery occlusion (P<0.05). CONCLUSIONS This study for the first time shows the presence of activated T-lymphocytes in remote unaffected myocardial regions in approximately two thirds of patients with recent AMI. Because these cells are associated with persistent infarct-related artery occlusion, our data may suggest that an antigenic stimulus present also in the myocardium triggers an immune response that may be critical to precipitate artery occlusion.

Abstract
BACKGROUND C-reactive protein (CRP) is a predictor of early and late outcome after coronary angioplasty, but there is scant data on its impact on the outcome after coronary artery bypass grafting (CABG). METHODS The predictive value of preoperative CRP was evaluated in a series of 764 patients who underwent on-pump CABG. RESULTS During the in-hospital stay, 13 patients (1.7%) died, 45 (4.5%) developed low cardiac output syndrome, and 28 (3.7%) suffered minor or major cerebrovascular complications. Patients with a preoperative serum concentration of CRP>/=1.0 mg/dL had a higher risk of overall postoperative death (5.3% vs 1.1%, p = 0.001), cardiac death (4.4% vs 0.8%, p = 0.002), low cardiac output syndrome (8.8% vs 3.7%, p = 0.01), and any cerebrovascular complication (4.4% vs 3.5%, p = 0.66). Preoperative serum concentration of CRP>/=1.0 mg/dL was significantly more frequent among patients with history of myocardial infarction, diabetes, lower limb ischemia, low left ventricular ejection fraction, NYHA class IV, and in those undergoing urgent or emergency operation. At multivariate analysis, preoperative serum concentration of CRP >/= 1.0 mg/dL (p = 0.01, O.R.: 6.97) and left ventricular ejection fraction (p = 0.01, O.R.: 0.95) were independent predictors of postoperative death. Postoperative mortality rate was 0.3% among patients with preoperative CRP < 1.0 mg/dL and an ejection fraction >/=50%, whereas it was 21.4% among those with a preoperative CRP >/= 1.0 mg/dL and an ejection fraction less than 50% (p < 0.0001). CONCLUSIONS Preoperative serum concentration of CRP in patients undergoing on-pump coronary artery bypass surgery is an important determinant of postoperative outcome.

Abstract
Patients without traditional cardiovascular risk factors continue to suffer from cardiovascular events, which has prompted a search for novel markers to better assess cardiovascular risk. Inflammatory biomarkers have surfaced as prime candidates, given the integral role of inflammation in atherosclerosis. C-reactive protein (CRP) measurements in particular have emerged as powerful predictors of cardiovascular risk in a broad spectrum of patient populations. Newer high sensitivity CRP assays now in use are standardized and reproducible, and can detect variations in CRP below the limit of standard assays. In primary prevention populations, studies have shown up to a 2-4-fold increased risk of cardiovascular events in healthy patients with elevated CRP levels. In this population, models incorporating CRP and lipid parameters appear to predict risk significantly better than lipids alone. In patients with established cardiovascular disease and in patients undergoing percutaneous coronary interventions, CRP levels may help predict short- and long-term prognosis, identifying subgroups of patients at increased risk of recurrent events. CRP levels may also prove useful in targeting therapy for primary and secondary prevention, by identifying patients who would most benefit from medications such as statins and aspirin. This review presents an overview of the data regarding CRP measurement for cardiovascular risk assessment.
