Quantifying RVD in Patients With Old Myocardial Infarction


Speckle-tracking echocardiography effectively quantified and characterized the RV systolic function and its association with the LV myocardial impairment in patients with OMI. Our data showed that longitudinal RV systolic strain depends highly on longitudinal LV systolic strain, especially in patients having high plasma BNP levels. These results may indicate that longitudinal RV dysfunction following MI does not owe fully to excessive afterload but also due to neurohormonal activation which causing ventricular remodeling response to altered LV wall stress. Application of speckle-tracking echocardiography to conventional measurements of ventricular function could provide a more thorough and quantitative pathophysiological characterization of functional RV adaptation following MI.
