Short term effect of right ventricular function after invasive treatment of proximal right coronary artery lesion tissue doppler imaging and speckle tracking study

Background: Coronary Artery Disease (CAD) is the most frequent type of cardiac illness. Worldwide. Aim: To compare the short-term outcome of right ventricular functions after invasive treatment by primary percutaneous coronary intervention (PCI) versus rescue percutaneous coronary intervention (PCI) in acute infero-posterior myocardial infarction without right ventricular (RV) infarction utilizing speckle tracking echocardiography (STE) and tissue Doppler imaging (TDI). Patients and methods: The present study was included100 patients diagnosed as acute infero-posterior STEMI without RV infarction and admitted in coronary care unit of Al-Azhar Assiut university hospital and Sohag cardiac institute between 1st December 2021and 11 January 2023. Results: The LV EF value in Baseline Echo was significantly reduced compared to Follow-up Echo, while RVEDA and RV ESA values were significantly increased in Baseline Echo compared to Follow-up Echo. Additionally, the FAC value was significantly lower in Baseline Echo than in Follow-up Echo, and the TAPSE value also showed a significant decrease in Baseline Echo compared to Follow-up Echo. RV S' Velocity in Baseline Echo was significantly lower than in Follow-up Echo, while IVCT, IVRT, and MPI values were notably higher. In contrast, the ET value was significantly decreased in Baseline Echo compared to Follow-up Echo. Conclusion: The results of this investigation illustrated that the right ventricular function is affected after inferio-posterior MI treatment, especially in the rescue PCI group. There is a need for larger studies to draw a solid conclusion.
