Increased diffusion in the brain of professional boxers: a preclinical sign of traumatic brain injury?
Boxers had higher diffusion constants than those in control subjects. Our data suggest that microstructural damage of the brain associated with chronic traumatic brain injury may elevate whole-brain diffusion. This global elevation can exist even when routine MR findings are normal.
E/e' > 15, PASP elevation, and LVH on preoperative TTE predicted postoperative pulmonary edema, and E/e' > 15 predicted MACE in the patients who underwent low- or intermediate-risk noncardiac surgery. Thus, we believe that clinicians need to be cautious when providing perioperative care to patients with high E/e' ratios who are indicated for TTE.
