In CKD, LVH is a near-constant feature with echo showing thick, bright echoes from IVS. The LV mass increases, partly due to physiological hypertrophy ,also contributed by deposits of uremic middle molecules and fluid collection in the interstitium as myocardial edema.This, is recognised as T 2 weighted MRI signals. Chronic fluid stasis may progress to myocardial fibrosis. (Kidney Blood Press Res 2018;43:134–142 )  

Effect of Frusemide on myocardial edema 

We know, loop diuretics cause aggressive depletion of ECF volume and to a lesser extent Interstitial fluid. The effect of diuretic on myocardial water content is a poorly studied parameter.(Still more visible to a shrewd echocardiographer)

Effect of dialysis

While the effect of diuretics on myocardial edema is not consistent, however, we have observed definite regression of myocardial thickness, mass, and rigidity following dialysis. This transforms into a better LV systolic and diastolic function. At least in one patient, we have observed  the E velocity shrunk more than 50% the next day following dialysis pushing them to lower grades of HFpEF( A potential study topic.)

Final message 

The Improvement of the functional class of CKD patients immediately after dialysis is not only attributable to the removal of excess fluid and toxic uremic molecules, regression of myocardial edema plays an important role.
