MERITnI - Mindray-hs-cTnI Assay: Analytical and Clinical Evaluation for the Diagnosis and RIsk AssessmenT of Myocardial InfarctIon.

The Mindray High Sensitivity Troponin-I Measurement System is an in vitro diagnostic test for the quantitative determination of high sensitivity cardiac troponin I (hs-cTnI) in human serum or plasma.

The Mindray High Sensitivity Troponin-I Measurement System is to be used as an aid in the diagnosis and rule out of acute myocardial infarction (AMI).

Study purpose/objective:

• Determine the sex-specific 99th percentile upper reference limits (URLs) for the Mindray hs-cTnI assay using the CL-1200i Instrument.
• Method comparison across the dynamic range of cTnI concentrations between the Mindray hs-cTnI assay and the Abbott Alinity hs-TnI assay used in clinical practice at Hennepin Healthcare/Hennepin County Medical Center.
• Evaluate the clinical performance of the Mindray hs- cTnI measuring system for the diagnosis of myocardial infarction (MI), for early rule out MI and myocardial injury, and assessment of 30-day safety outcomes in patients presenting to the emergency department (ED) in whom serial cTnI measurements (0h, 2h, 4h, 6h) are obtained on clinical indication at Hennepin Healthcare / Hennepin County Medical Center (Minneapolis, MN USA) to rule-in and rule-out MI.

Inclusion Criteria:

1. Presents to the ED, or ambulatory care center equivalent, with signs or symptoms suspicious of a possible ACS/ischemic event.
2. Baseline cTn-I measurement and one additional cTn-I measurement at two hours after the first measurement.
3. At least one 12-lead electrocardiogram

Exclusion Criteria:

1. Less than 21 years old
2. Pregnancy
3. Trauma
4. Declines to participate or has indicated that their blood/ medical information cannot be used for investigational purposes
5. Did not present through the ED
6. Transferred from an outside hospital or clinic
7. Has already been enrolled in the study
