Native Hawaiians and Pacific Islanders have more bleeding strokes at an earlier age than other people independent of methamphetamine abuse, according to research presented at the American Stroke Association's International Stroke Conference 2013.
"Drug abuse is a huge problem here and it definitely is a cause of hemorrhagic stroke," said Kazuma Nakagawa, M.D., lead investigator and assistant professor of medicine at the University of Hawaii. "But Native Hawaiians and Pacific Islanders are experiencing this form of stroke at a younger age even without methamphetamine use. It's not all about methamphetamines, but possibly due to poor vascular health."
Intracerebral hemorrhage (ICH) is the most common type of hemorrhagic stroke. It occurs when a weakened blood vessel inside the brain ruptures and leaks blood into surrounding brain tissue.
In a retrospective study of ICH patients treated at an Oahu hospital, Native Hawaiians and Pacific Islanders (NHPI) had five times the risk of ICH stroke before age 45 when compared to non-Hispanic white controls. Of the 384 ICH patients studied in 2006-10, 19 percent were Native Hawaiian/Pacific Islanders, 65 percent were Asians and 16 percent non-Hispanic whites.
Besides genetics, environmental factors - such as diet, stress, unhealthy lifestyles and a lack of good health care - could also affect the higher incidences, he said. "These groups need a different intensity of treatment in the community. There needs to be a focus on controlling hypertension, diabetes and weight management."
The retrospective study was based on chart reviews in one institution. So researchers are conducting a prospective study to determine the causes of the strokes in young Native Hawaiians and Pacific Islanders.
Cerebral hemorrhage accounts for about 10 percent of 795,000 annual strokes in the United States. This form of stroke is often more severe and disabling than ischemic stroke, which is due to blockage in an artery.
