Etiologic Mechanisms, Myocardial Changes and Prognosis of Patients With MINOCA
Study Details
Study Description
Brief Summary
This prospective trial will include 150 patients with myocardial infarction with non-obstructive coronary arteries (MINOCA). A thorough clinical, laboratory and imaging evaluation will be performed by novel biomarkers and modern imaging techniques (heart magnetic resonance imaging and noninvasive testing). Moreover, two different treatment groups will be distinguished. Additionally, a retrospective analysis of patients meeting MINOCA criteria will be performed.

Detailed Description
Primary goals The primary trial goal is to assess the etiologic mechanisms of myocardial damage in patients with MINOCA as well as to evaluate a variety of therapeutic strategies for these patients.
Secondary goals
-
To assess functional and morphological myocardial changes in patients with MINOCA;
-
To assess the true prevalence and prognostic relevance of MINOCA (all-cause mortality and MACE);
-
To test the effect of conventional acute MI therapies (BB, ACEI, ARB, CCB, statins, anti-platelet agents) on MACE (death and myocardial infarction) and all-cause mortality in patients with MINOCA;
-
To test the diagnostic and prognostic role of several biomarkers (sST2, BNP, cTnI, CRP, copeptin, procalcitonin, MR-proADM, galectin-3) in patients with MINOCA;
-
To assess the impact of MINOCA with respect to chronic health status, such as persistent angina symptoms, impairment in quality of life, and depression;
-
To evaluate systemic microcirculation status and assess its effect on long term outcomes.
-
To evaluate hospital mortality and all-cause death within 6 and 12 months follow-up;
-
To determine recurrent hospitalizations within 30-days, 6 and 12 months follow-up;
-
To assess peak creatine kinase, creatine kinase-MB and troponin levels during hospital stay;
-
To determine quality of life at 6 and 12 months assessed using the Euroqol 5D (EQ-5D) questionnaire (www.euroqol.org).

Eligibility Criteria
Criteria
Inclusion Criteria:

detection of a rise and/or fall of cardiac troponin(cTn) values with at least one value above the 99th percentile upper reference limit (URL) and with at least one of the following:
-
symptoms of acute myocardial ischaemia;
-
new ischaemic ECG changes;
