High school biology teaches students that the basic structure of muscle contraction is the sarcomere, a repeating micrometer-sized unit that dictates the anatomy of both cardiac and skeletal striated muscle. The thick (myosin) and thin (actin) filaments within the sarcomere interlock, such that each thick filament is surrounded by six thin ones.

Troponin T is a protein in the heart muscle which can be released into the blood when there is damage to the heart muscle as in a heart attack. Even small quantities of troponin T can be detected by a high sensitivity assay (laboratory estimation). hsTnT is more sensitive than conventional TnT 4. More myocardial injury will be detected with hsTnT : The assay is able reliably to detect lower levels than prior assays and in doing so, there may be a measurable amount of cardiac injury even in patients who present due to nonAMI situations. Results w- ill be reported out with the following comment: The newest high sensitive 5th generation cardiac TnT assay (hsTnT) detects an elevation in TnT levels within 1 hour of the onset of myocardial infarction.1 It also measures low levels of TnT that were undetectable in prior assay generations, in subjects that do not have myocardial infarction. The new hsTnT assay is reported to be able to hsTnT Reference Interval (males and females, age >1 year) <14 ng/L *Any result above the reference range will be flagged.

point for a healthy population (13 pg/mL), hsTnT had 62% sensitivity, 89% specificity, 38% positive predictive value, and 96% negative predictive value for ACS. Compared with the cardiac troponin T method, hsTnT detected 27% more ACS cases (P.001), and an hsTnT above the 99th percentile strongly predicted ACS (odds ratio 9.0, 95% confidence Due to the increased sensitivity of hsTNT, some (non-AS) chronic conditions may now give an abnormal result.

Zvýšení hladiny hsTnT v případě klinické symptomatologie a EKG změn svědčí pro infarkt myokardu. U nemocných s bolestí na hrudi v tr-vání pod 6 hodin a nezvýšenou hodnotou hsTnT se doporučuje druhý odběr již za 3 hodiny, v pří-padě zvýšení nad 14 ng/l (nad hodnotu cut off) je prokázána léze myokardu. Patients with increased hsTnT and plaque burden (n = 53) showed the highest incidence for hard cardiac events (annual rate, 12.7%), followed by those with either increased hsTnT or plaque burden (n = 145; annual rate = 0.44%, P < .03), while those with lower hsTnT and plaque burden exhibited excellent outcomes and no hard event during the follow-up duration (n = 210; annual rate = 0%, P < .001).

While the hsTnT assays have improved diagnostic yield in AMI, a number of non-cardiac conditions are associated with elevations in hsTnT (e.g. heart failure, tachyarrhythmias, pulmonary

Since conventional cardiac Troponin assays have a low sensitivity for diagnosing AMI in the first hours after myocardial necrosis, high-sensitive assays have been developed. The aim of this study was to assess the cost effectiveness of a high The positive and negative predictive value of the hsTnT using the 13 p/ml cutpoint were 38% and 76%, respectively. Overall, the hsTnT method detected 27% more ACS cases than did the cTnT method (p=0.001), Hoffman and colleagues report, and multivariable linear regression analysis confirmed that an hsTnT result above the 99th percentile strongly predicted ACS, at an odds ratio of 9.0. Biological variation indices are comparable between healthy subjects and HF patients for a broad spectrum of biomarkers.

In all athletes, median creatine kinase (CK) and CK-MB were 130 U/L (IQR 103–176) and 20 U/L (IQR 17–24) pre-marathon, respectively. Mean hsTnT and NTproBNP levels in the hsPDA group were higher compared to the group without an hsPDA, with levels being 251.54 vs 161.6 pg/ml, p < 0.01 for hsTnT and 18181.02 vs 3149.23 pg/ml, p hsTnT.
