  Purpose

The new assay of troponins T (highly sensitive troponins) detects concentrations much lower than before. Few data are currently available on their kinetics during acute coronary syndrome, especially in regard to the correlation with CK MB. The aim of the present study is to describe the kinetic of highly sensitive troponins in acute coronary syndrome, to correlate it with the concentration of CK MB, and possibly to evaluate their prognostic value with respect to infarct size .

Primary Outcome Measures:
  • Evaluation of troponins kinetic in acute coronary syndromes. [ Time Frame: 72 hours ] [ Designated as safety issue: No ]

Estimated Enrollment: 500
Study Start Date: June 2013
Estimated Study Completion Date: November 2013
Estimated Primary Completion Date: November 2013 (Final data collection date for primary outcome measure)
Detailed Description:

Patients who meet the inclusion criteria will have a highly sensitive troponins and CKMB assays q 8hr for the first day, and q 12h for the next 2 days. If clinically not indicated, the blood sample can be cancelled at any time, as in the case of a patient with an initial suspicion of acute coronary syndrome in which the final diagnosis is something else. Only patients with a definitive myocardial infarction will be analyzed.

Subgroup analyses includes ST-elevation MI, Non ST-elevation MI, revascularization vs no revascularization, procedural myocardial infarction.

Another analysis conducted is the correlation between the values ​​of troponin and infarct size by echocardiography (in patients who have an echocardiography 2-7 days post AND 2-6 months post myocardial infarction)

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population

All consecutive patients presenting to the emergency department or being hospitalized for any reason in which we suspect an acute coronary syndrome.

Criteria

Inclusion Criteria:

  • >= 18 years-old
  • Clinical suspicion of an acute coronary syndrome; (will be analyzed only patients with aposteriori definitive diagnosis of unstable angina or myocardial infarction)

Exclusion Criteria:

  • none
