Abstrakt: Background: It is widely recognized that the right ventricle plays a significant role in the prognosis of numerous diseases. However, the assessment of right ventricular function (RV) has not been given much attention until recently. This study used speckle-tracking echocardiography (STE) to assess RV functions in ischemic cardiomyopathy (ICM) patients.
Results: This study included 74 patients diagnosed with ischemic cardiomyopathy (ICM) and an ejection fraction (EF) of less than 50%. Although all the selected patients had normal RV systolic function by tricuspid annular plane systolic excursion (TAPSE), a considerable percentage of them had subtle RV systolic dysfunction, which could be identified by right ventricular free wall longitudinal strain (RV FWLS) (36.5%) and right ventricular global longitudinal strain (RV GLS) (55.4%). Moreover, the mean RV FWLS was significantly higher than RV GLS (- 20.4 ± 5.08% vs. - 17.5 ± 6.89%), respectively. Advanced left ventricle (LV) adverse remodeling was associated with subtle RV dysfunction. Using multivariate regression analysis, increased E/e' (p = 0.016, CI 1.135-3.423) and RV myocardial performance index (MPI) (p = 0.007, CI 0.000-0.007) were identified as independent factors of impaired RV FWLS with the greatest effectiveness.
Conclusion: When standard RV measures are normal in patients with ICM, RV systolic strain analysis offers an incremental utility to detect subtle abnormalities in RV function, especially in resource-constrained settings where cardiac magnetic resonance (CMR) is not practical.
