Definitions

1. Troponin is related to left ventricular mass and predicts all-cause and cardiovascular mortality in hemodialysis patients.
2. Troponin is particularly efficient in diagnosing AMI up to two weeks after symptom onset and may remain elevated 10 to 14 days following ischaemia onset.

4. However, troponin is cleared via the kidneys which explain why decreased kidney function may result in increased blood concentrations.

Presence

Addition

1. Troponin I tests in addition to CK-MB measurements contribute to a lower rate of misdiagnoses.
2. In addition, acute myocardial stretch from increased cardiac preload can result in proteolysis of troponin and cause its release.

2. Early repeat sampling of cardiac troponin (e.g., 2–4 h after presentation) may be appropriate if tied to therapeutic strategies (Level of Evidence: C).
3. The short-term risk of adverse clinical outcomes in patients with ACS complicated by HF is directly proportional to the level of troponin elevation (65).

Degradation

1. Preload induces troponin I degradation independently of myocardial ischemia.
