European Society of Cardiology (ESC)/ European Society of Anesthesiology (ESA) highlighted that anesthesiologist has a leading role in perioperative cardiovascular assessment and management in the year of 2014. During cardiovascular assessment one can rely on cooperation of multi-disciplinary specialists like: other anesthesiologists, cardiologists and surgeons. For the purpose of precise systematization and decision making the Lee score or NSQUIP database can be used besides the traditionally used ASA score...

AIM: To characterise the changes in high sensitivity troponin T (hsTnT) in incident haemodialysis patients. BACKGROUND: Previous studies had shown that stable chronic haemodialysis patients have elevated cardiac troponin compared to the general population. Cardiac troponin on incident haemodialysis patients had not been characterised. METHODS: This prospective descriptive study included all patients who started haemodialysis in Auckland City Hospital over 18 months...

AIMS: Biomarkers can be used for diagnosis, risk stratification, or management of patients with heart failure (HF). Knowledge about the biological variation is needed for proper interpretation of serial measurements. Therefore, we aimed to determine and compare the biological variation of a large panel of biomarkers in healthy subjects and in patients with chronic HF. METHODS AND RESULTS: The biological variability of established biomarkers [NT-proBNP and high-sensitivity troponin T (hsTnT)], novel biomarkers [galectin-3, suppression of tumorigenicity 2 (ST2), and growth differentiation factor 15 (GDF-15)], and renal/neurohormonal biomarkers (aldosterone, phosphate, parathyroid hormone, plasma renin concentration, and creatinine) was determined in 28 healthy subjects and 83 HF patients, over a period of 4 months and 6 weeks, respectively...

BACKGROUND: Growth-differentiation factor-15 (GDF-15) is an emerging humoral marker for risk stratification in cardiovascular disease. Cardiac-surgery-associated acute kidney injury (CSA-AKI), an important complication in patients undergoing cardiac surgery, is associated with poor prognosis. The present secondary analysis of an observational cohort study aimed to determine the role of GDF-15 in predicting CSA-AKI compared with the Cleveland-Clinic Acute Renal Failure (CC-ARF) score and a logistic regression model including variables associated with renal dysfunction...

AIM: Risk assessment of patients undergoing transcatheter aortic valve implantation (TAVI) remains difficult. Biomarkers have been shown to provide potential prognostic information. Here, we aimed to analyze whether the biomarker high-sensitivity Troponin T (hsTNT) could be used to improve risk stratification. METHOD: We prospectively enrolled 267 patients undergoing TAVI. Biomarkers (hsTNT and NTproBNP) were measured 1 day before, and 3 and 7 days postprocedure...

AIMS: Elevated levels of high-sensitivity troponin are seen in a significant proportion of stable patients undergoing elective coronary assessment. Multiple variables have been associated with troponin levels. The present analysis sought to identify variables independently associated with elevations of troponin and their relative strength of association with this biomarker. METHODS AND RESULTS: Stable patients undergoing elective coronary angiography and echocardiographic assessment were enrolled...

BACKGROUND: Adrenomedullin and endothelin-1 are hormones with opposing effects on the cardiovascular system. Adrenomedullin acts as a vasodilator and seems to be important for the initiation and continuation of the hyperdynamic circulatory response in sepsis. Endothelin-1 is a vasoconstrictor and has been linked to decreased cardiac performance. Few studies have studied the relationship between adrenomedullin and endothelin-1, and morbidity and mortality in septic shock patients. High-sensitivity troponin T (hsTNT) is normally used to diagnose acute cardiac injury but is also prognostic for outcome in intensive care...

AIMS: Interleukin-6 (IL-6) contributes to atherosclerotic plaque destabilization and is involved in myocardial injury during ischaemia-reperfusion. Interleukin-6 is therefore a potential therapeutic target in myocardial infarction (MI). We hypothesized that the IL-6 receptor antagonist tocilizumab would attenuate inflammation, and secondarily reduce troponin T (TnT) release in non-ST-elevation MI (NSTEMI). METHODS AND RESULTS: In a two-centre, double-blind, placebo-controlled trial, 117 patients with NSTEMI were randomized at a median of 2 days after symptom onset to receive placebo (n = 59) or tocilizumab (n = 58), administered as a single dose prior to coronary angiography...

BACKGROUND: Accumulating evidence suggests interactions between bone and energy metabolism in patients with type 2 diabetes (T2DM). Recently, the role of osteocalcin (OC), an osteoblast-specific protein, was suggested as a regulator of glucose metabolism and fat mass. METHODS: We determined the circulating levels of OC with two different assays in T2DM patients. The relationship of OC with established biomarkers of bone and mineral metabolism as well as biomarkers related to cardiovascular risk was also investigated...

INTRODUCTION: Routine measurement of cardiac biomarkers such as troponin T (TnT) is recommended perioperatively, especially in high-risk vascular surgery. Long-term prognosis is worse even in those with nonspecific perioperative myocardial injury. However, a clear understanding of these biomarker profiles and how they should affect patient management is lacking. METHODS: We examined the perioperative profile of high-sensitivity TnT (hsTnT) release in 85 patients undergoing elective major vascular surgery...

Anthracycline-induced cardiotoxicity influences treatment selection and may negatively affect clinical outcomes in lymphoma patients. While epirubicin induced cardiotoxicity less often than the same dose of doxorubicin in breast cancer, higher doses of epirubicin are required in lymphoma regimens for equivalent efficacy. Whether a higher dosage of epirubicin also induces cardiotoxicity less often than doxorubicin in lymphoma remains unknown. We therefore administered 6-8 cycles of cyclophosphamide, vincristine and prednisone (CEpOP) +/- rituximab (R) with either epirubicin (CEpOP) or doxorubicin (CHOP) to patients (N=398) with untreated diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma grade 3 (FLG3)...

OBJECTIVES: Remote ischemic preconditioning (RIPC) involves the phenomenon whereby transient episodes of limb ischemia induced by cuff inflation provide cardioprotection. The effectiveness of RIPC in vascular surgery is uncertain. This randomized, controlled trial was designed to investigate the potential of two episodes of RIPC to provide myocardial protection in patients undergoing vascular surgery. DESIGN AND METHODS: Patients undergoing an elective major vascular procedure (open abdominal aortic aneurysm (AAA) repair, endovascular aneurysm repair, and lower-limb bypass grafting) were randomized into RIPC group (n = 42) or control group (n = 43)...

OBJECTIVES: The aim of this study was to determine if a baseline high-sensitivity troponin T (hsTnT) value ≤99th percentile upper reference limit (0.014 μg/l ["low hsTnT"]) identifies patients at low risk for adverse outcomes. BACKGROUND: Approximately 85% of patients who present to emergency departments with acute heart failure are admitted. Identification of patients at low risk might decrease unnecessary admissions. METHODS: A post-hoc analysis was conducted from the RELAX-AHF (Serelaxin, Recombinant Human Relaxin-2, for Treatment of Acute Heart Failure) trial, which randomized patients within 16 h of presentation who had systolic blood pressure >125 mm Hg, mild to moderate renal impairment, and N-terminal pro-brain natriuretic peptide ≥1,600 ng/l to serelaxin versus placebo...
