The extracellular matrix degradation markers as predictors of left ventricular systolic dysfunction among patients with STEMI

Abstract

The purpose of the study. To determine predictor value of the extracellular matrix degradation markers relative to the occurrence of left ventricular systolic dysfunction among patients with STEMI determined. Materials and methods. The results of the study are based on data obtained from a comprehensive survey of 162 patients with STEMI. The first group consisted of 145 patients with STEMI and left ventricular ejection fraction > 45% (median age – 59 (52–64) years); the second group consisted of 17 patients with STEMI and left ventricular ejection fraction 45%, (p 45%, (p 483,7 PG/ml, the sensitivity was 76,47% and the specificity was 62,07% for left ventricular systolic dysfunction among patients with STEMI. The calculated relative risk was for matrix metalloproteinase-9 > 5247,9 PG/ml for the development of left ventricular systolic dysfunction was 7,139, 95% CI 1,686–30,218. For the level of tissue inhibitor of matrix metalloproteinase-2 > 483,7 PG/ml, the relative risk was 4,271, 95% CI 1,455–12,536 for the development of left ventricular systolic dysfunction. Conclusions. Patients having STEMI with left ventricular ejection fraction 5247.9 PG/ml level relative risk of the developing left ventricular systolic dysfunction in patients with STEMI increases by 7.139 times.
