Furthermore, in 3 additional multivariate models that included a wide variety of contemporary biomarkers with established prognostic efficacy (i.e., ST2, GDF-15, Cystatin C, hs-CRP, Myeloperoxidase, NT-proBNP, TIMP-1, Adiponectin, RDW, hemoglobin, and Erythropoietin), MMP-1 remained an independent predictor of all-cause mortality at 5 years. Similar results were obtained when the analyses were restricted to the subpopulation of patients presenting with acute coronary syndrome.</p> </sec> <sec> <title id="sectitle0035">Conclusions</title> <p id="abspara0030">Elevated levels of MMP-1 are associated with an increased risk of long-term all-cause mortality in patients with known or suspected coronary disease that is independent of a variety of clinical, angiographic, and laboratory variables, including a whole host of contemporary biomarkers with established prognostic efficacy representing multiple different pathophysiologic processes.</p> </sec> </abstract>
