A novel strain relaxation index (SRI) is introduced to assess diastolic function by CMR, using myocardial deformation during LV relaxation. We investigate how SRI relates to standard diastolic parameters by echocardiography (echo). We also relate SRI to mass to volume ratio (MVR) by CMR, which is seen to increase in diastolic dysfunction. SRI accounts for both very early myocardial relaxation and tissue compliance.
SRI, a novel indicator of diastolic function, as measured from tagged CMR showed good relation to MVR by CMR and standard echo parameters of diastolic function.
