Circulating Matrix Metalloproteinase-28 Levels Are Related to GRACE Scores and Short-Term Outcomes in Patients with Acute Myocardial Infarction

الملخص EN

Objective.

To investigate the relationship between the level of matrix metalloproteinase-28 (MMP-28) in patients with acute myocardial infarction (AMI) and the global registry of acute coronary events (GRACE) scores as well as their short-term prognosis.

Methods.

Two hundred eleven patients with AMI were enrolled, and their basic clinical characteristics were collected for determining the GRACE score.

We measured the plasma levels of MMP-28 and other biomarkers in the study population.

The association of MMP-28 levels with cardiac events and cardiac deaths occurring within 30 days of discharge was evaluated with multivariable Cox proportional hazard models.

Results.

The MMP-28 levels were significantly higher in patients with acute ST-elevation myocardial infarction (STEMI) than in patients with non-ST-elevation myocardial infarction (NSTEMI) (P<0.01).

Correlation analysis showed that the level of MMP-28 was positively correlated with the GRACE score in patients with AMI (R2=0.366, P<0.05).

Cox multivariate regression results showed that MMP-28 was associated with cardiovascular events during the hospitalization and 30 days after discharge (P<0.01).

In addition, Kaplan–Meier analysis showed that cardiac events and deaths were significantly higher in patients with MMP-28≥1.21 ng/mL (all P<0.01).

Conclusion.

There is a correlation between the plasma MMP-28 level and GRACE score in patients with AMI.

MMP-28 is also associated with cardiovascular events and cardiovascular deaths during the hospitalization of patients and within 30 days of discharge.
