Cognitive-behavioural stress management does not improve biological cardiovascular risk indicators in women with ischaemic heart disease: a randomized-controlled trial.

Journal of internal medicine·2006

Area of Science:

  • Neurology
  • Cardiovascular Medicine
  • Clinical Trials

Background:

  • Ischaemic stroke is caused by interrupted blood flow to the brain.
  • Haemodilution aims to improve blood flow and reduce brain infarct size.

Purpose of the Study:

  • To assess the effects of haemodilution in acute ischaemic stroke.

Main Methods:

  • Systematic review of 18 randomized controlled trials.
  • Included trials started treatment within 72 hours of stroke onset.
  • Data extracted and quality assessed by two independent reviewers.

Main Results:

  • Haemodilution did not significantly reduce short-term or long-term mortality.
  • No significant improvement in death, dependency, or institutionalization.
  • A trend towards reduced venous thromboembolism, but no increased cardiac events.

Conclusions:

  • Haemodilution therapy for acute ischaemic stroke lacks proven benefits for survival or functional outcomes.
  • Results are inconclusive, suggesting potential for both modest benefit and moderate harm.
  • Further research is needed to clarify the role of haemodilution in stroke management.
