Özet
Objective: We aimed to evaluate effect of termination property of left anterior descending (LAD) on tissue Doppler echocardiography (TDE) parameters in patients experiencing their first anterior myocardial infarction (AMI) who had undergone successful primary percutaneous coronary intervention (PCI) Methods: A prospective, cross-sectional observational study was performed. Eighty-four patients were enrolled in the study. Echocardiography was performed during the first three days of AMI. Conventional TDE measurements were obtained from right ventricular (RV) and four left ventricular (LV) walls: for the systolic function - mitrel annular TDE systolic velocity - Sm, for diastolic function - mitral annular TDE early and late diastolic velocities - Em, Am, transmitral early and late diastolic velocities ratio - E/A, and combined systolic and diastolic function - myocardial performance index (MPI). Coronary arteries were evaluated and patients were divided into two groups (non-wrapped LAD and wrapped LAD) according to the termination properties. Student-t, Mann-Whitney U and Chi-square tests, bivariate Pearson and Spearman correlation analyses were used for statistical analysis. Results: Baseline characteristics and conventional echocardiographic parameters of the patients were similar. There was a statistically significant difference for the anterior wall Sm parameter, whereas there was no substantial difference for Em, Am and MPI values. The anterior wall Sm was more affected in patients with non wrapped LAD than in patients with wrapped LAD (6.70 +/- 1.66 and 7.44 +/- 1.66 cm/s; p=0.036,). The anterior Sm parameter was uniquely correlated with LAD termination status when compared with other independent parameters (r=0.236, p=0.036). Conclusion: We showed that termination of LAD is important for the anterior wall systolic functions in the early stage of AMI treated successfully. (Anadolu Kardiyol Derg 2012; 12: 465-71)
