TNNI3 and coronary artery disorder: Despite its near ubiquitous use, the troponin assay requires the serial cTnI measurements (up to 9 h) and one measurement demands at least 15–30 min for the antibody–antigen recognition on which the method depends to occur.[4, 18] Furthermore, for non‐MI CHD, troponin does not provide any valuable diagnostic information, and angiography plus electrocardiogram (the gold standard diagnostic method) is used instead, which can be invasive and is thus not practical for general screening.[19] Therefore, improved methods to detect CHD, particularly both MI and non‐MI, are needed.
