Methods: The literary search criteria used the Mesh Terms cited in the "Search strategies" section. One hundred and four papers submitted for eligibility analysis were collated, twenty-six studies were selected. The review protocol was based on the criteria of literary search with the use of mesh terms in the main databases such as Pubmed, Medline, Bireme, EBSCO, and Scielo. Conclusion: The patient was diagnosed with this pathology based on a prior acute myocardial infarction and the presence of coronary http://mo.qingres.com Metalloproteinases as Predictors of Coronary Disease Sofia Braile Sabino et al.
