More Londoners than ever survive cardiac arrest

More than one in five Londoners now survive an out-of-hospital cardiac arrest (21.5 per cent*) compared to one in ten (10.9 per cent) four years ago.

The 2009/10 Cardiac Arrest Annual Report, published recently, attributes the increase to more effective patient care from London Ambulance Service staff, as well as significant levels of bystanders performing cardiopulmonary resuscitation (CPR).

Medical Director Fionna Moore said: “These latest figures show that through our staff getting to patients quickly and delivering effective life-saving care Londoners whose hearts have stopped beating have more chance of survival than ever before.

“If someone collapses and stops breathing it means their heart has stopped and 999 should be called for an ambulance immediately.

“Last year in just over a third of cases bystanders gave CPR to patients in cardiac arrest while an ambulance was on the way, but it’s a simple fact that if more people learnt this life-saving technique and used it, more patients would survive. Effective CPR doubles a person’s chances of survival.

“Getting a defibrillator, a machine that can shock the heart to restart it again, to the patient quickly, also greatly improves someone’s chances of survival.”

The London Ambulance Service is responsible for over 500 public-access defibrillators in places such as train stations, airports, leisure centres and tourist attractions around the capital, and for training staff who work in those locations to use them.

*The cardiac arrest survival figure is calculated using the internationally-recognised Utstein method. The calculation takes into account the number of patients discharged alive from hospital who had resuscitation attempted following a cardiac arrest of presumed cardiac aetiology, and who also had their arrest witnessed by a bystander and an initial cardiac rhythm of ventricular fibrillation or ventricular tachycardia.

Additional figures from London Ambulance Service Cardiac Arrest Annual Report 2009/10 – Authors Gurkamal Virdi, Lynne Watson and Dr Rachael Donohoe

  • Around two thirds of cardiac arrests in London occurred in the home
  • Of those that occurred in public, just under half took place in the street
  • Between a third and a half of all cardiac arrests were witnessed by bystanders (44 per cent)
  • However, bystanders only gave cardio-pulmonary resuscitation (CPR) in just over a third of all cardiac arrests (35 per cent)
  • The average age of a cardiac arrest patient was 67
  • The majority of patients (64 per cent) were male
  • Female patients were on average six years older than males (71 compared with 65)
  • Cardiac arrests occurred most frequently on a Monday
  • The highest number in a single month occurred in December (11 per cent) and the fewest in April (5.6 per cent)

Notes to editors:

  • A cardiac arrest occurs when a person’s heart stops. Someone in cardiac arrest will lose consciousness, will not be breathing and will have no signs of circulation. A cardiac arrest is not the same as a heart attack, the latter being when a clot in the artery restricts the flow of blood to the heart. The terms ‘cardiac arrest’ and ‘heart attack’ are not interchangeable. Patients in cardiac arrest are effectively dead unless they are promptly resuscitated.
  • London’s cardiac arrest survival figure using the Utstein method has increased from 10.9 per cent in 2005/06 to 21.5 per cent in 2009/10
  • In 2009/10 the London Ambulance Service received over 120,000 calls from patients reporting potential cardiac or chest pain related problems
  • The London Ambulance Service provides free CPR training to the public and to businesses at a cost.
