Stroke Burden Surges Among US Adults

METHODOLOGY:

  • Data from 1990 to 2021 on ischemic stroke, intracerebral hemorrhage (ICH), and subarachnoid hemorrhage (SAH) in the US were obtained from the Global Burden of Disease study.
  • Cases of stroke were identified using criteria from the World Health Organization and the International Classification of Diseases (ICD), 9th and 10th Revisions.
  • Researchers evaluated the incidence and prevalence of stroke, as well as mortality, disability-adjusted life years (DALYs) lost, years of life lost, and years lived with disability owing to stroke.

TAKEAWAY:

  • In 2021, the US recorded 0.41 million incident stroke cases (76% ischemic stroke) and 6.3 million prevalent stroke cases (5.1 million, 0.75 million, and 0.45 million involving ischemic stroke, ICH, and SAH, respectively). There were also 0.2 million stroke-related deaths and a loss of 3.9 million DALYs.
  • From 1990 to 2021, the crude prevalence increased by 66% for ischemic stroke, 78% for ICH, and 71% for SAH, and incident cases increased by 10%, 28%, and 50%, respectively.
  • Individuals aged 15-49 years had a 3% increase in the prevalence of stroke, and Alaska, Nevada, and Arkansas reported the greatest state-level increases in prevalence.
  • However, age-standardized rates for stroke incidence were reduced by 33%, mortality by 31%, and DALYs lost by 28%, with larger declines in each of these measures for ischemic stroke than for hemorrhagic stroke subtypes.
