MitoQ and Ischemic Conditioning To Assess Vascular Health Outcomes (MITO Study)

Summary

Stroke survivors have compromised vascular function which may contribute to secondary stroke risk, cardiovascular disease, and may limit their exercise tolerance. Preliminary data shows a single bout of ischemic conditioning or oral ingestion of an over-the-counter antioxidant supplement called MitoQ may improve vascular function and muscle activity in individuals post-stroke.

Interventions

• Device
  Ischemic Conditioning

  The cuff will be placed around the proximal, non-affected thigh and inflated for 5 minutes in a supine or semi-reclined position, then released for a 5-minute recovery period. Five cycles of inflation and recovery will be performed (45 minutes total).These inflations will be done using a cuff similar to what is used for taking blood pressure.

• Dietary Supplement
  Antioxidant Supplement

  MitoQ is an over the counter supplement that increases delivery to the mitochondria. Similar to studies performed in middle age/older adults and individuals with peripheral arterial disease, we will administer 1 single oral dose of 80mg of MitoQ or a placebo pill. As MitoQ reaches peak concentrations at \~40 to 60 minutes after ingestion, we will wait 45 minutes (time matched to Ischemic conditioning).
