The study investigates the impact of enhanced external counterpulsation (EECP) therapy on cognitive performance in long COVID patients who experienced cognitive impairment.* -
A total of 80 patients were analyzed, revealing significant improvements in cognitive scores after EECP treatment, particularly for those who had cognitive impairment at the start.* -
Although the study lacks a negative control group, it suggests that EECP therapy is safe and potentially effective for improving cognitive function in long COVID patients.*

Objective: The aim of this study is to determine the effects of enhanced external counterpulsation (EECP) in patients with long COVID and objectively assessed cognitive impairment.

Design: A retrospective evaluation of long COVID patients referred for EECP, with cognitive sequela, and having completed an objective digital assessment before and after therapy. Patients had either cognitive impairment or no cognitive impairment at baseline. We assessed changes in composite score using multifactor analysis of variance. Multiple linear and logistic regression analyses were conducted to evaluate several independent variables.

Results: Eighty long COVID patients (38 cognitive impairment vs. 42 no cognitive impairment) were included for analyses. All baseline characteristics were well matched. There was significant improvement in composite score post EECP in those with objective cognitive impairment at baseline. There were no notable documented safety concerns.

Conclusions: This is the first study showing that EECP led to significant improvement in cognitive functioning of long COVID patients with objectively defined cognitive impairment. Although a lack of a negative control group is a limitation of this study, EECP seems to be highly safe and effective with the potential for widespread application.
