ABSTRACT
ObjectiveTo assess external counterpulsation (ECP) effects on cognitive and functional decline in early AD.MethodsThis 12-month, multicenter, blinded, randomized, sham-controlled trial enrolled 190 patients with early AD (MCI due to AD or mild AD per NIA-AA clinical criteria). Participants received either full-pressure ECP (150-300 mmHg) or sham (25 mmHg): 3-5 weekly one-hour sessions for 35 treatments, then twice-weekly through six months. Assessments occurred at baseline and weeks 6, 12, 18, 24, 36, and 52. Primary endpoints included ADCS-ADL, ADAS-cog-14, and VADAS-cog.ResultsFull-pressure ECP significantly improved ADCS-ADL scores versus sham (mean change 2.57 vs. -0.49; p=0.036) and VADAS-cog scores (9.95 vs. 5.22; p=0.005) at 12-24 weeks. Benefits persisted through 52 weeks despite treatment cessation at 6 months. No serious device-related adverse events occurred.ConclusionsFull-pressure ECP therapy significantly improved cognition and ADL compared to sham treatment in early AD. ECP represents a novel therapeutic approach warranting further investigation.
