Uitkomstmaten
Primaire uitkomstmaten
The primary endpoint is a composite of cardiovascular mortality or a clinical diagnosis of a non-fatal acute coronary syndrome during 1-year follow-up.
Achtergrond van het onderzoek
BIOMArCS is a multi-centre, prospective, observational study with 1-year follow-up of 700 patients after ACS, either with or without ST-elevation. Patients with at least two cardiovascular risk factors are included, so that the primary endpoint (cardiovascular mortality or repeat non-fatal ACS) is likely to occur in 10% of the cohort. Venapuncture is planned every fortnight during the first half-year and monthly thereafter. Biomarker patterns prior to the endpoint will be determined at the end of follow-up in the (suspected) 70 cases and compared to 210 event-free, matching controls.
Doel van het onderzoek
1. Vascular inflammation becomes activated several days to weeks before an acute coronary syndrome;
2. Biomarkers of vascular inflammation, distorted lipid metabolism, endothelial dysfunction, diminished endothelial regenerative capacity, hypercoagulability and myocardial ischemia become elevated before the event;
3. Hence, serial biomarker measurements might be used to identify vulnerable periods in the life-time of patients with established cardiovascular disease (as well as in individuals with prevalent but yet unrecognised cardiovascular disease), during which they are at increased risk of developing an acute coronary syndrome;
4. An imminent acute coronary syndrome might be prevented by future intensified medical treatment, or by a percutaneous coronary intervention.
Onderzoeksopzet
Total follow-up duration is 1 year. Patient interviews and blood sample collection and are planned during hospital admission for and acute coronary syndrome and subsequently every two week during the first half year of follow-up and monthly during the last half year of follow-up.
Onderzoeksproduct en/of interventie
None, strictly observational post-ACS study.
