Summary

Early defibrillation by general practitioners significantly improves survival rates for cardiac arrest patients with acute myocardial infarction. Equipping more doctors with defibrillators could reduce deaths from coronary heart disease.

Investigation in general practice of patients with suspected heart failure. How should the essential echocardiographic service be delivered?

British heart journal·1995

Area of Science:

  • Cardiology
  • Emergency Medicine
  • General Practice

Background:

  • Acute myocardial infarction (AMI) can lead to cardiac arrest.
  • General practitioners (GPs) are often the first medical responders.
  • Early defibrillation is critical for survival in cardiac arrest.

Purpose of the Study:

  • To investigate cardiac arrest modes in AMI patients attended by GPs.
  • To evaluate the effectiveness of early defibrillation by GPs.

Main Methods:

  • Retrospective observational study in British general practice.
  • GPs were equipped with defibrillators.
  • Outcomes measured included cardiac rhythm, survival to hospital admission, and discharge.

Main Results:

  • When resuscitation initiated within 4 minutes, 90% had shockable rhythms; >70% survived to hospital, 60% discharged alive.
  • Delayed resuscitation resulted in fewer shockable rhythms and lower survival rates.
  • If arrest occurred in GP surgery, 85% admitted alive, 75% discharged alive.

Conclusions:

  • GPs managing AMI patients should be equipped with defibrillators.
  • Widespread community defibrillator deployment can reduce coronary heart disease mortality.
