Mortality Risk Greater if Cerebral Hemorrhage is in Sleep

Twenty-one percent of 'asleep' patients die within month, versus 4.9 percent of 'awake' patients

MONDAY, April 17 (HealthDay News) -- Patients who have an intracerebral hemorrhage while asleep are more than four times as likely to die within a month of the event than patients who experience the hemorrhage while they are awake, according to a study published in the April issue of the American Journal of Hypertension.

Yoshinari Nagakane, M.D., of the National Cardiovascular Center in Osaka, Japan, and colleagues looked at 129 patients who had experienced primary intracerebral hemorrhage.

Of the 19 patients who had the hemorrhage while asleep, 21.1 percent died within a month, compared with 4.9 percent of those who had the hemorrhage while awake. In general, the volume of the hemorrhage was larger in those who had the event when sleeping than those who were awake (32.6 versus 16.7 mL).

"Our findings indicate that intracerebral hemorrhage during the asleep period may be more detrimental compared with intracerebral hemorrhage during the awake period, causing larger hematoma and higher mortality rates," the authors conclude.
