| Abstract | PURPOSE: Methylenetetrahydrofolate reductase (MTHFR) is an enzyme involved in endothelial nitric oxide synthase (eNOS) coupling and homocysteine metabolism. The rs1801133 polymorphism of the MTHFR gene affects risk of coronary artery disease. We assessed its influence on 5-year survival of patients with ST-elevation acute myocardial infarction (STEMI). MATERIAL/METHODS: The study group comprised consecutive patients with STEMI. Genotyping was performed with a TaqMan SNP Genotyping Assay using the ABI 7500 Real Time PCR System (Applied Biosystems). The analyzed end-point was all-cause 5-year survival. RESULTS: The study group comprised 637 patients (mean age 62.3 ± 11.9 years; 25.1% females, n=160; 5-year mortality 16.3%, n=104). The percentages of TT, CT and CC genotypes were: 10.8 (n=69), 39.7 (n=253) and 49.45 (n=315), respectively. No significant differences in clinical characteristics were identified between the genotypes (p>0.05 for all parameters). Eleven (15.9%) TT homozygotes, 40 (15.8%) heterozygotes and 53 (16.8%) CC homozygotes died during follow up (p=0.99 log-rank test). TT homozygotes presented only weak and insignificant tendency towards higher mortality rates in subgroups of patients ≤75 years old (15.6 vs. 11.54%, p=0.35) or with intermediate risk according to the GRACE risk score (13.3% vs. 8.76%, p=0.42). CONCLUSIONS: The rs1801133 polymorphism did not show significant association with 5-year survival. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
