@entity452 stress echocardiography (DSE) is widely used during follow-up after cardiac transplant for the diagnosis of allograft vasculopathy. We investigated the effect of donor-recipient age difference on the ability to reach target heart rate (HR) during DSE. All cardiac transplant @entity1 who were undergoing DSE over a 3-year period in a single institution were reviewed. Target HR was specified as 85%*(220 - @entity1 age). Further @entity1 and donor demographics were obtained from the local transplant database. 61 @entity1 (45 male, 55  12 years) were stressed with a median dose of 40mcg/kg per min @entity452 . Only 37 @entity1 (61%) achieved target HR. Donor hearts were mostly younger (mean 41  14 years, P<0.001), with only 11 @entity1 (18%) having donors who were older than they were. @entity1 with older donors required higher doses of @entity452 (median 50 vs 30mcg/kg per min, P<0.001) but achieved a @entity299 (mean 93% vs 101%, P=0.003) than those with younger donors did. @entity1 with older donors were less likely to @entity299 (18% vs 67%, P=0.003). In conclusion, donor-recipient age difference affects the likelihood of @entity299 and should be considered when a @entity1 is consistently unable to achieve 'adequate' stress according to the @entity1 's age.
