Study for Evaluation of Newly Onset Chest Pain and Rapid Diagnosis of Myocardial Necrosis

Completed

• Conditions: Acute Myocardial Infarction

• Registration Number: NCT03227159
• Lead Sponsor: Universitätsklinikum Hamburg-Eppendorf

Brief Summary

This is a national multi-center, prospective surveillance study in patients with suspected acute coronary syndrome. Eligible patients must present to one of the participating Emergency Departments within 24 hours from the time of symptom onset. Approximately 2000 patients \>18 and \<85 years of age are planned to be enrolled.

Upon enrollment in the Emergency Department, a venous blood sample will be obtained from each patient for analysis. The patient's diagnostic work-up, treatment and disposition will continue per the standards of the treating institution. Results will be recorded for ECGs, any cardiac biomarkers measured at the site and any follow-up cardiac objective tests performed for evidence of coronary artery disease and/or myocardial damage (exercise treadmill, coronary angiography, cardiac thallium or technetium scintigraphy, etc).

The Principal Investigator at each site will evaluate the results of the diagnostic cardiac tests performed for that patient to determine whether each patient enrolled at their site has a final diagnosis of ACS.

The status of each patient will also be assessed at 1 month and 6 months after enrollment for intercurrent Major Adverse Cardiac Events (MACE), including myocardial infarction, cardiac revascularization and death.

Primary Outcome Measures

Name	Time	Method
Diagnosis of acute coronary syndromes	30 days	The primary end-point of the study is the early diagnosis of acute coronary syndromes using a combined analysis of multiple markers compared to single marker analyses (final diagnosis of ACS as reason for hospital admission).
