Feasibility Of 2D Strain For Assessing Myocardial Function In Trained And Not-trained Renal Transplant Recipients

Abstract

Table: No title available.PURPOSE: Deformation parameters are normally employed to early discover a possible myocardial damage. This aspect is particularly important in post-renal- transplant syndrome where cardiovascular mortality remains elevated and where physical activity is normally allowed. This study aims to verify the role of Longitudinal (Lo) Strain in two groups of renal transplant recipients at different level of physical training. METHODS: A group of 8 transplant recipients (aged 45±5 yrs) following a program of moderate (75% of the max effort) aerobic exercise added to a low resistance exercise for at least 3 times a week for 1 year was compared to a group of 6 subjects not trained. All participants underwent an echocardographic exam with the evaluations of the standard 2D parameters and by Lo Strain calculation by a dedicated software (ESAOTE XStrain). RESULTS: All parameters were within the normal range. Lo Strain was feasible in all subjects. The limited number of subjects did not allow to detect statistically significant differences between the groups, despite the higher values of Lo Strain values in apical segments. CONCLUSIONS: There is evidence of feasibility of Lo ST evaluation in post transplant patients. Lo Strain confirms the normal LV function in renal recipients and plays a role in following the progressive improvement of the myocardial function in post transplant renal syndrome submitted to the exercise program. More studies are necessary to evaluate the possible contribution of physical exercise to the improvement of deformation parameters.
