High sensitive cardiac troponin assays have become the gold standard in the diagnosis of an acute type 1 myocardial infarction (MI) in the absence of ST-segment elevation. Several acute or chronic conditions that impact cardiac troponin levels in the absence of a MI might lead to a misdiagnosis of MI. For example, patients with impaired renal function as well as elderly patients often present w...
1. Myofibrils from human skeletal muscle contained regulatory proteins exhibiting similar electrophoretic behaviour to those present in rabbit skeletal muscle. 2. All human skeletal muscles examined contained two forms of troponin I corresponding to the forms already characterized in fast and slow rabbit muscle. 3. The ratios of the amounts of the two forms of troponin I in different human skel...
A systematic review was carried out to study the pattern of high-sensitivity cardiac troponin release after running (search performed on PubMed, ISI Web of Knowledge and Scopus databases). A total of ten reports were identified as meeting the pre-specified criteria (eight using high-sensitivity troponin T and two using high-sensitivity troponin I). The papers were published between 2009 and 201...
Controversies concerning whether cardiac biomarkers can be released in the absence of cell death have existed for years. The initial observations were made with lactate dehydrogenase (LDH), the 134-kDa enzyme that was found to be released from cells or organs in response to tissue injury in the absence of overt cell death (1 ). Similar issues arose with creatine kinase (CK) and CK isoenzyme MB ...
It is well established that cardiac biomarkers are universally raised post-cardiac surgery. This due to various preoperative, intraoperative, and postoperative factors. At present, no reliable tool or model considers intraoperative factors predict morbidity mortality after Troponin T as a single serial measurement morbidity, an attractive diagnostic the direct relationship myocardial damage ava...
Alveolar rhabdomyosarcoma is an aggressive tumour in adulthood, in which cardiac troponin T seems to be a tumour marker and course parameter. We present the clinical course of a young man suffering from this rare disease and the development of troponin T during therapy. Noninvasive cardiac imaging was used to exclude cardiac involvement, myocardial infarction or inflammation processes.
W ith advances in technology, a new era in troponin assays is approaching. Previous-generation troponin assays have been used as diagnostic and prognostic markers in acute coronary syndrome patients and for risk stratification to guide triage decisions and aid in treatment selection. New, high-sensitivity troponin assays represent an important advance with added sensitivity for cardiac myocyte ...
Hijazi, Z. 2013. New Risk Markers in Atrial Fibrillation. Acta Universitatis Upsaliensis. Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Medicine 906. 76 pp. Uppsala. ISBN 978-91-554-8680-8. Atrial fibrillation (AF) confers an independent increased risk of stroke and death. The stroke risk is very heterogeneous and current risk stratification models based on clinic...
BACKGROUND AND PURPOSE Elevated cardiac troponin is a marker of cardiac disease and has been recently shown to be associated with embolic stroke risk. We hypothesize that early elevated troponin levels in the acute stroke setting are more prevalent in patients with embolic stroke subtypes (cardioembolic and embolic stroke of unknown source) as opposed to noncardioembolic subtypes (large-vessel ...
Hypertrophic cardiomyopathy is a multigenetic cardiac disease with autosomal dominant pattern of inheritance and incomplete penetrance, with the exclusion of those cases caused by mutations in the mitochondrial genome. The disease is usually caused by mutations in several sarcomeric contractile protein genes. Mutations have been found in four genes that encode components of the thick filament: ...
