摘要

Tissue inhibitors of metalloproteinase (TIMPs) bind to active matrix metalloproteinase (MMPs), and thereby inhibit their proteolytic activity. We investigated the role of polymorphisms in the gene for TIMP-1 and serum levels of TIMP-1 in association with postmyocardial infarction (MI), left ventricular (LV) dysfunction, and symptoms of acute heart failure (AHF) in patients treated with primary percutaneous coronary intervention. Methods: In total, 556 patients with STEMI were evaluated. Levels of TIMP-1 were measured at admission and 24h after MI onset. The TIMP-1 exon 5 SNP rs4898 (F124F with T>C) located at X chromosome was assayed. Results: TIMP-1 levels were higher for men with AHF as well as for men with LV dysfunction (ejection fraction [EF]<40%). According to multivariate analysis, the TIMP-1 level was a factor with an independent negative relationship to EF and AHF in men. An independent relationship between exon 5 TIMP-1 gene polymorphism and EF, AHF or TIMP-1 level was not documented. Conclusion: These results provide evidence that a higher level of circulating TIMP-1 is independently associated with worse EF and AHF.
