Comparison of right ventricular functions according to infarct localization using advanced echocardiographic methods in myocardial infarction with ST elevation

26619

Objectives: In this study, we aimed to compare the ef¬fects of infarct localization in patients with ST Elevated Myocardial Infarction (STEMI) on the right ventricular (RV) functions by using advanced echocardiographic methods. Materials and methods: A total of 89 patients with STEMI were included into the study and patients were divided to three groups as anterior, isolated-inferior and inferior+RV MI groups. In addition to standard echocardiographic mesurements, RV tissue doppler, RV Ejection Fraction (RVEF), Myocardial performance index (MPI) and TAPSE measurements of all patients were performed between 24-72 hours after the event. Results: Compared to groups, RV functions in inferior MI with RV involvement group were deteriorated. Tricuspid annular plane systolic excursion (TAPSE) value for the inferior MI with RV involvement (19±1mm) group were lower than those for Inferior MI group without RV involvement (23±1mm) and anterior MI (23±1mm) (p 0.05). The RV MPI value for inferior MI group with RV involvement (0.76±0.14) were found to be higher than those for anterior (0.64±0.1) and inferior MI (0.56±0.1) group without RV involvement (p 0.05). Peak Sm (r = -0.35, p = 0.01), TAPSE (r = -0.47, p 0.001) and RV EF (r = -0.46, p 0.001) showed a negative correlation with RV MPI value. Furthermore, RV tricuspid E/A rate (r = -0.19, p = 0.7) and RV free wall tissue doppler Em/Am rate (r = -0.26, p = 0.01) displayed a negative correlation with RV MPI value. Conclusions: Use of advanced methods addition to the conventional echocardiographic methods in STEMI patients, could produce more valuable information to evaluate RV functions and provide a positive impact on treatment strategies.
