High-sensitivity cardiac troponin thresholds used to diagnose MI and injury after cardiac surgery may need to be considerably higher than those currently recommended, a new study suggests.

For that oldest group, age-adjusted 99th percentile thresholds improved specificity to 91.3% at the cost of a major loss in sensitivity (down from 81.6% to 55.9%) for an overall positive ...

Cardiac troponin was high in 1085 (just under 5.5%) patients. Some 1782 (9%) patients died after a year, and a total of 2825 (14%) had died just over 2 years (809 days) later.

Elevated troponin linked to mental stress ischemia in heart disease patients Higher baseline levels of heart muscle damage marker Date: April 3, 2016 Source: Emory Health Sciences Summary: People ...

For example, in PROSPER, which measured troponin T, 87.5% of the 4402 participants had detectable concentrations, with a median of 7 ng/L, and 85% of values were below the high-normal cutoff of 14 ...

Key takeaways: High levels of cardiac troponin I were linked to all-cause mortality after slightly more than 2 years. The relationship existed even in patients with no signs of heart disease. In a ...

Also, critical illness can cause high troponin levels (at much higher levels than you may have had) in people who don’t have heart blockages. (A median of 0.57 ng/mL was found in people with ...

The researchers compared their new highly sensitive troponin I assay (hsTnI) to tests for other biomarkers, and found at hospital admission, the test had an 82.3 percent accuracy in diagnosing a ...
