New evidence bolsters theory e-cigarettes may increase stroke risk

There is new evidence that bolsters a possible link between e-cigarette use and increased risk of stroke, according to researchers from the University of Colorado Boulder. Their study, conducted in humans, showed that circulating endothelial cell-derived microvesicles (tiny, bubble-like particles released into the bloodstream during inflammation) from e-cigarette users have adverse effects on key factors responsible for regulating brain blood flow. Changes in these factors contribute to the “promotion, development and progression” of ischemic stroke.
