Subjects enrolled in this study will sign and informed consent and have 4 blood samples drawn at different time points during their emergency department visit. In addition, data will be collected about the patient's health history, hospital procedures, and final diagnosis. The enrolling center will also contact the patients at 30-days, 3 months and 6 months to inquire about their condition and survival.
Blood samples collected in this study will be sent to the sponsor organization for long-term storage and analysis in the future for novel blood markers as they become available. No genetic testing will be conducted on these samples.
This is a prospective, multi-center, observational, and sample procurement study of adult subjects presenting to an Emergency Department (ED) in whom ACS is in the differential diagnosis. Subjects must present to one of the participating EDs within 6 hours or less from the time of symptom onset, and must have experienced at least 5 minutes of chest discomfort.
Those ED patients with possible ACS who meet the inclusion/exclusion criteria will be approached for study enrollment by trained research personnel.
The patient's diagnostic work-up and treatment will continue per the standards of the treating institution. As indicated by their clinical presentation, it is anticipated that all patients in this study will have an electrocardiogram (ECG) upon admission to the ED and if the patient is found not to have an ST-elevation myocardial infarction (STEMI), objective cardiac testing will be conducted for evidence of MI. The Principal Investigator at each site will evaluate the results of the objective cardiac tests combined with biomarker evidence of myocardial necrosis to determine whether or not a patient enrolled at their site has a final diagnosis of ACS.
Cardiac events and procedure, such as angioplasty-stenting and coronary artery bypass surgery (CABG), will be recorded during the index ED visit, hospitalization and post-hospital follow-up period. Subjects will have a 30-day, 3 month and 6 month follow-up contact by phone or medical chart review to collect this information on cardiac events, procedures and survival.
Blood samples collected at several time points during the index ED visit will be used for future testing of novel blood markers as they become available.
