Fig. 1From: Diagnostic accuracy of left atrial function and strain for differentiating between acute and chronic myocardial infarctionMale, 56 year, LA measurements by CMR feature tracking. (A and B) LA longitudinal strain in the four- and two-chamber views at end-diastole. (C and D) The LA strain and strain rate curve. Global endocardial LA strain and strain rate values were recorded. εs, reservoir strain; εa, booster strain; εe, conduit strain; εe = εs-εa. SRs, peak positive strain rate;SRe, peak early-negative SR; SRa, peak late-negative SR.Back to article page
