Clinical and Diagnostic Value of Highly Sensitive Cardiac Troponins in Arterial Hypertension

Figures & data

Figure 1 The main reasons of increased blood serum cardiac troponins which may not be associated with AMI.^9,26–29

Table 1 Classification of Troponin Immunoassays According to Their Sensitivity

Classification of Immunoassays According to Their Sensitivity	Lower Detection Limit (Minimum Detectable Concentration) of Cardiac Troponins, ng/L	The Number of Examined Healthy Patients in Whom Cardiac Troponins are Determined (Above 0 ng/L but Not More Than 99th Percentile), %
Low sensitive immunoassays	500–1000 ng/L	0%
Moderately sensitive immunoassays	50–100 ng/L	Less than 50%
Highly sensitive 1st generation immunoassays	Dozens ng/L	50–75%
Highly sensitive 2nd generation immunoassays	Dozens ng/L	75–95%
Highly sensitive 3rd generation immunoassays	Several ng/L	More than 95%
Highly sensitive 4th generation immunoassays (ultrasensitive)	Less than 1 ng/L	99–100%

Table 2 Levels of hs-cTnI for Stratification of CVD Risk in the General Population⁴³

Сardiovascular Risk	The Concentration of hs-cTnI in the Serum of Men	The Concentration of hs-cTnI in the Serum of Women
Low	<4 ng/L	<6 ng/L
Moderate	4–10 ng/L	6–12 ng/L
High	>10 ng/L	>12 ng/L
