Promising 3-year-old filly Elate suffered a heart fibrillation in the Group 3 McKee Family Sunline Vase (2100m) last start, causing concern for her connections leading into Saturday's Group 1 Al Basti Equiworld Dubai New Zealand Oaks (2400m).
The Roger James and Robert Wellwood-trained filly was heading into the race offthe back of victory in the Listed Oaks Prelude (1800m) at New Plymouth last month and looked a major threat in the running before fading late.
"She had a heart fibrillation last start," Wellwood said.
"We have just got to rule a line through that race.
"Troy [Harris, jockey] said she felt super in the running and travelled up very nicely. He was really happy, but unfortunately she did have a heart fibrillation.
"She's well, she converted back to her normal heart-rate the next morning. She looks in super order," Wellwood said. "It does give you a bit of uncertainty doing it the run before, but we are pretty happy where we are at with her."
Meanwhile, the Cambridge trainers welcomed Group 1 performer Hypnos back to their barn two weeks ago.
The 3-year-old son of Reliable Man won the Listed Uncle Remus Stakes (1400m) at Ellerslie on Boxing Day last year before dead-heating for second in the Group 1 Levin Classic (1600m) at Trentham in January.
Hypnos subsequently finished unplaced in the Karaka Million 3YO Classic (1600m) before heading to the spelling paddock.
He is now being set for a tilt at the Group 3 Inglis Sales Cambridge Breeders' Stakes (1200m) at Te Rapa next month before potentially targeting some Australian spoils.
"Hypnos has just come back into work. He may have a trial prior to the Cambridge Breeders at Te Rapa or he might just head fresh into that," Wellwood said.
"We will get a line on him when he runs in that and we may look to head to Queensland with him, but we will make that decision after the Cambridge Breeders."
