Methods: 44 consecutive patients with chest pain and pathological findings on CCTA (>50% stenosis or high calcium score (>400 HU) with undetermined severity) were included. These patients underwent SE with acquisition of 3DSTE at rest and at peak stress.
Results: Mean age was 63.9±9.9 years. 90% were men. The images of the 44 patients were processed with automatic tracking and manual corrections. 11 patients developed inducible ischaemia during SE. Patients with ischaemic response showed significant reductions in 3D area strain (AS) compared to resting values. The 33 patients without inducible ischaemia showed, however, a significant increase in this parameter. Results are shown in table 1.
Conclusion: 3D area strain SE could help to identify patients with inducible ischemia. However, further studies are need to confirm these data.
