|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||130 participants|
|Intervention Model:||Parallel Assignment|
|Intervention Model Description:||Randomized clinical trial with 1:1 allocation to EECP therapy and best medical therapy|
|Masking:||Single (Outcomes Assessor)|
|Masking Description:||Outcome will be assessed by independent assessors for stroke/TIA recurrence within 6 months as well as change in cerebral vasodilatory reserve on acetazolamide challenged HMPAO- SPECT of brain.|
|Official Title:||External Counterpulsation Therapy for Symptomatic and Severe Steno-occlusive Disease of Intracranial Internal Carotid or Middle Cerebral Artery and Impaired Cerebral Vasodilatory Reserve|
|Actual Study Start Date :||January 8, 2019|
|Estimated Primary Completion Date :||January 7, 2023|
|Estimated Study Completion Date :||May 7, 2023|
Experimental: EECP therapy
Half of the study sample will be allocated to EECP therapy (35 sessions) of 1-hour each. Acetazolamide challenged HMPAO-SPECT will be performed before randomization and repeated 2-months after the completion of EECP therapy. MRI of the brain would be performed after completion of EECP therapy to document any silent stroke.
Device: Enhance External Counterpulsation Therapy
EECP therapy would be administered to this group for 1-hour a day for a total of 35 sessions
No Intervention: Best Medical Therapy
This group will receive the best medical therapy according to our institutional practice and as per the recommendations of American Stroke Association.
- Improvement in cerebral vasodilatory reserve [ Time Frame: at baseline and after 2 months of the completion of EECP therapy ]To evaluate whether Enhanced External Counter-Pulsation (EECP) therapy would lead to a change in cerebral vasodilatory reserve (CVR) by at least 4% in patients with severe and recently symptomatic stenosis of intracranial carotid (ICA) or middle cerebral artery (MCA).
- Stroke TIA/recurrence [ Time Frame: at 6 months ]To evaluate the impact of EECP on recurrence of cerebral ischemic event in patients with severe and recently symptomatic stenosis of ICA or MCA.
- Impact of EECP on cognition [ Time Frame: at 6 months ]To evaluate the impact of EECP on change in neurocognitive performance by at least 2 points (60 minutes protocol suggested by NINDS harmonization workshop) in patients with severe and recently symptomatic stenosis of ICA or MCA.
