Head-to-head comparison of plasma cTnI concentration values measured with three high-sensitivity methods in a large Italian population of healthy vol…
2019
Abstract Background The study aim is to compare cTnI values measured with three high-sensitivity (hs) methods in apparently healthy volunteers and patients admitted to emergency department (ED) with acute coronary syndrome enrolled in a large multicentre study. Methods Heparinized plasma samples were collected from 1511 apparently healthy subjects from 8 Italian clinical institutions (mean age: 51.5 years, SD: 14.1 years, range: 18–65 years, F/M ratio:0.95). All volunteers denied chronic or acute diseases and had normal values of routine laboratory tests. Moreover, 1322 heparinized plasma sample were also collected by 9 Italian clinical institutions from patients admitted to ED with clinica…
Cardiovascular Mortality in Chest Pain Patients: Comparison of Natriuretic Peptides With Novel Biomarkers of Cardiovascular Stress.
2016
Natriuretic peptides are the standard biomarker for risk stratification in cardiovascular disease. Novel biomarkers of cardiovascular stress might allow refinement in risk stratification for patients with acute coronary syndrome (ACS). We tested the performance of these novel biomarkers for cardiovascular risk stratification in patients who presented with ACS.In the AtheroGene study, 873 patients presented with ACS in the emergency department. Biomarkers measured were: B-type natriuretic peptide (BNP), N-terminal pro BNP (NT-proBNP), midregional proatrial natriuretic peptide, midregional proadrenomedullin (MR-proADM), copeptin, and troponin I. The median follow-up time was 4 years and durin…
Multimarker risk strategy for predicting 1-month and 1-year major events in non-ST-elevation acute coronary syndromes.
2005
The aim of this study was to define the utility of the combined measurement of troponin I, myoglobin, C-reactive protein, fibrinogen, and homocysteine to predict risk in non-ST elevation acute coronary syndromes.Troponin I, myoglobin, high-sensitivity C-reactive protein, fibrinogen, and homocysteine were measured in 557 consecutive patients admitted to our institution for non-ST elevation acute coronary syndrome. The risk for major events (death or nonfatal myocardial infarction) at first month and at first year follow-up was analyzed.In a multivariate model adjusting for baseline characteristics and electrocardiographic changes, the only biomarkers related to major events at first month we…
The risk factor age in normotensive patients with pulmonary embolism: Effectiveness of age in predicting submassive pulmonary embolism, cardiac injur…
2015
Abstract Introduction Right ventricular dysfunction (RVD), submassive pulmonary embolism (PE), elevated systolic pulmonary artery pressure (sPAP), elevated cardiac troponin I (cTnI) and old age are well-known risk factors for poor outcome in acute normotensive PE. The aim of this analysis was to calculate age cut-off values to predict submassive PE, cardiac injury, RVD and elevated sPAP in normotensive PE patients. Methods Retrospective analysis of clinical, laboratory, radiological and echocardiographic data of normotensive PE patients (2006–2011) was performed. Receiver operating characteristic (ROC) curves and Youden indexes were used to test the effectiveness of using patients' ages at …
Renal function as a cofactor for risk stratification and short-term outcome in acute pulmonary embolism
2017
Abstract Background In addition to right ventricular dysfunction (RVD) and myocardial injury, impaired renal function is connected with poorer prognosis in pulmonary embolism (PE). We aimed to investigate renal function as a cofactor for risk stratification in PE. Methods Data from 182 patients with PE, treated between May 2006 and June 2011, were analysed retrospectively. PE patients with elevated creatinine were compared with those with normal values. Logistic regression models were calculated to investigate associations between creatinine and myocardial necrosis, RVD and in-hospital death. Prognostic performance of creatinine for prediction of myocardial necrosis and RVD were computed. R…
No evidence of adverse cardiac remodeling in former elite endurance athletes
2016
Background: The impact of high exercise loads on a previously healthy heart remains controversial. We examined the consequences of decades of strenuous endurance exercise at the highest competition level on heart dimensions and volumes as well as on serum biomarkers of cardiac fibrosis/remodeling. Methods and results: We compared echocardiographic measurements and serum biomarkers of cardiac fibrosis/remodeling [troponin I, galectin-3, matrix metallopeptidase-2 and -9, N-terminal pro-brain natriuretic peptide, carboxy-terminal propeptide of type I procollagen, and soluble suppressor of tumorigenicity-2 (sST-2)/interleukin(IL)-1R4] in 53 male athletes [11 former professional ('elite') and 42…
Growth Differentiation Factor-15 (GDF-15) Levels Are Associated with Cardiac and Renal Injury in Patients Undergoing Coronary Artery Bypass Grafting …
2014
International audience; Objective: Growth differentiation factor-15 (GDF-15) has been identified as a strong marker of cardiovascular disease; however, no data are available concerning the role of GDF-15 in the occurrence of organ dysfunction during coronary artery bypass grafting (CABG) associated with cardiopulmonary bypass (CPB). Methods: Five arterial blood samples were taken sequentially in 34 patients from anesthesia induction (IND) until 24 h after arrival at the intensive care unit (ICU). Plasma levels of GDF-15, follistatin-like 1 (FLST1), myeloperoxidases (MPO), hydroperoxides and plasma antioxidant status (PAS) were measured at each time-point. Markers of cardiac (cardiac-troponi…
Troponin I Assay for Identification of a Significant Coronary Stenosis in Patients with Suspected Acute Myocardial Infarction and Wide QRS Complex
2016
Background Common ECG criteria such as ST-segment changes are of limited value in patients with suspected acute myocardial infarction (AMI) and bundle branch block or wide QRS complex. A large proportion of these patients do not suffer from an AMI, whereas those with ST-elevation myocardial infarction (STEMI) equivalent AMI benefit from an aggressive treatment. Aim of the present study was to evaluate the diagnostic information of cardiac troponin I (cTnI) in hemodynamically stable patients with wide QRS complex and suspected AMI. Methods In 417 out of 1818 patients presenting consecutively between 01/2007 and 12/2008 in a prospective multicenter observational study with suspected AMI a pro…

Sensitive Troponin I Assay in Early Diagnosis of Acute Myocardial Infarction
2009
BACKGROUND Cardiac troponin testing is central to the diagnosis of acute myocardial infarction. We evaluated a sensitive troponin I assay for the early diagnosis and risk stratification of myocardial infarction. METHODS In a multicenter study, we determined levels of troponin I as assessed by a sensitive assay, troponin T, and traditional myocardial necrosis markers in 1818 consecutive patients with suspected acute myocardial infarction, on admission and 3 hours and 6 hours after admission. RESULTS For samples obtained on admission, the diagnostic accuracy was highest with the sensitive troponin I assay (area under the receiver-operating-characteristic curve [AUC], 0.96), as compared with t…
