The PACIFIC trial directly compared Heartflow to SPECT and PET imaging, demonstrating superior diagnostic performance (AUC of 0.94 vs 0.70 and 0.87). This provides a powerful competitive weapon against companies providing these alternative technologies and creates pressure on healthcare providers to evaluate Heartflow's platform.
Filing excerpt
Using invasive FFR as the reference standard, the Heartflow FFRCT Analysis demonstrated the highest diagnostic performance for vessel-specific ischemia of all tested noninvasive tests, with an AUC (Area Under the Curve) of 0.94 compared with PET (0.87), CTA (0.83), and SPECT (0.70) (p < 0.001 for all).
