Active clinical trials for "Non-ST Elevated Myocardial Infarction"

This study is to validate 1-hour and 3-hours diagnostic strategy using Architect high-sensitivity cardiac troponin I (hs-cTnI) in Chinese patients with suspected Non-ST-elevation Myocardial Infarction (NSTEMI). The accuracy of 1-hour and 3-hours algorithm of NSTEMI using hs-cTnI assays will be evaluated in China emergency patients. This trail is going to determine the optimal diagnostic cut-off value of NSTEMI in Chinese population according to 24-hour or longer clinical diagnosis of MI in routine way.

The purpose of this registry is to depict the myocardial tissue characteristics in NSTEMI patients by CMR and other cardiac imaging modalities and to assess the prognostic value of imaging-derived indices. Information will be collected prospectively in about 2000 NSTEMI patients in 10 sites. Subjects will be followed for up to 5 years.

The objective of this research study is to test the accuracy of preexisting criteria versus expert interpretation for the diagnosis of acute coronary occlusion (major heart attack due to a completely blocked blood vessel). If our hypothesis proves to be true, this would provide a significant improvement in the care for patients who present to the hospital with possible symptoms of coronary ischemia (symptoms due to lack of blood flow to the heart). The primary analysis will be designed as a multi-center, retrospective case-control study.
