The relation between matrix metalloproteinase-1 promoter genotype and remodeling was studied in 42 patients after their first acute myocardial infarctions.
Therefore, we investigated whether the serum concentrations of OPG and RANKL correlate with the serum levels of metalloproteinase-1 (MMP-1), MMP-9 and tissue inhibitors of MMP-1 (TIMP-1), which are known regulators of myocardial healing in acute myocardial infarction (AMI) patients.
The MMP-3 5A allele was more frequent in patients with MI than in the control subjects (P=0.018 MI group-1, P=0.0059 MI group-2), whereas there was no disease association for MMP-1 genotypes.
Gelatin microspheres for the controlled release of MMP-1 plasmid DNA are promising for improving cardiac remodeling and function when they are administered during the chronic phase of MI.
Adding tissue inhibitor of matrix metalloproteinase-1 to the established risk profile improved risk discrimination of myocardial infarction ( p=0.039) and death (0.001).
