BACKGROUND Thoracic and cardiac irradiation increases the risk of pulmonary and cardiovascular disease. In addition, radiation, often in combination with chemotherapy, can cause treatment-related pneumonitis. Previously, we showed that the common marker for cardiac damage, troponin T, was not elevated by chemoradiation [Lung Cancer 62:351-355, 2008]. In this study, we explore whether dose-volum...

Cardiac biomarkers such as amino-terminal pro-B-type natriuretic peptide (NT-proBNP) and cardiac troponin T (cTNT) provide information on cardiovascular morbidity and mortality in patients with normal renal function. In a considerable number of chronic haemodialysis patients, both biomarkers - NT-proBNP and cTNT - are elevated despite the absence of cardiac ischaemia. The elevation of cardiac b...

The present study aims to reveal the changing patterns of cerebral biomarkers and the underlying predictive factors as a consequence of cardiac surgery. Literature retrieval of articles on S100 and S100B of recent 20 years were made in the MEDLINE database, Highwire Press and Google search. Quantitative data of S100 and S100B along with neuron-specific enolase were carefully screened, collected...

UNLABELLED Biomarkers unrelated to myocardial necrosis, such as cystatin C, copeptin, and mid-regional pro-adrenomedullin (MR-proADM), showed promise for cardiovascular risk prediction. Knowing whether they are comparable to cardiac biomarkers such as high-sensitive cardiac-troponin T (hs-cTnT) or N-terminal pro-Brain natriuretic peptide (NT-proBNP) in elderly patients with acute non-massive pu...

Clinicians have become increasingly sophisticated in their application of cardiac biomarkers in the management of acute coronary syndromes (ACS). In the 1950s, clinical investigators first reported that proteins released from necrotic cardiac myocytes could be detected in the serum and could aid in the diagnosis of acute myocardial infarction.1 The ensuing 40 years witnessed progressive improve...

In the last decade, the availability of the cardiac biomarkers N terminal pro-natriuretic peptide type-B (NT-proBNP) and troponins has radically changed the approach to diagnosis, staging, and response assessment of cardiac amyloidosis. Despite similar appearance at standard imaging, the main types of amyloidosis involving the heart are characterized by different rates of progression and differ...

Cardiac ischemia occurs when there is a supply versus demand mismatch in coronary blood flow. In patients who present with unstable angina, ischemia occurs due to partial or total occlusion of a coronary artery due to plaque rupture. In stable angina however, there is progressive vascular occlusion resulting ultimately in a luminal stenosis of greater than 70%, impeding blood flow to the distal...

OBJECTIVES To examine the relationship of cardiac biomarkers with postoperative acute kidney injury (AKI) among pediatric patients undergoing cardiac surgery. METHODS Data from TRIBE-AKI, a prospective study of children undergoing cardiac surgery, were used to examine the association of cardiac biomarkers (N-type pro-B-type natriuretic peptide, creatine kinase-MB [CK-MB], heart-type fatty aci...

The use of cardiac biomarkers in the intensive care setting is gaining increasing popularity. There are several reasons for this increase: there is now the facility for point-of-care biomarker measurement providing a rapid diagnosis; biomarkers can be used as prognostic tools; biomarkers can be used to guide therapy; and, compared with other methods such as echocardiography, the assays are easi...
