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 is a potential treatment to enhance blood flow to affected brain areas.

Purpose of the Study:

  • To evaluate the efficacy and safety of haemodilution in acute ischaemic stroke patients.
  • To synthesize evidence from randomized trials on haemodilution's effects.

Main Methods:

  • Systematic review of randomized controlled trials (RCTs) of haemodilution therapy.
  • Included trials initiated within 72 hours of stroke onset.
  • Data extraction and quality assessment by two independent reviewers.

Main Results:

  • Sixteen RCTs were analyzed, using various haemodiluting agents like dextran 40 and hydroxyethyl starch.
  • Haemodilution did not significantly reduce short-term or long-term mortality, or death and dependency.
  • A non-significant trend towards reduced venous thromboembolic events was observed.

Conclusions:

  • Current evidence does not support haemodilution therapy as a proven method to improve survival or functional outcomes in acute ischaemic stroke.
  • The overall results suggest potential for both modest benefit and moderate harm, warranting caution.
  • Further research may be needed to clarify the role of haemodilution in stroke management.
