18650 people with undiagnosed AF

We are helping to raise awareness about Atrial Fibrillation (AF) as part of the AF Association – Global AF Awareness Week 20–26 November 2017. So we’ve brought together some key information and resources on how AF can be detected.

What is AF?1

AF is an anomaly in the heart rhythm which can cause an irregular and often very fast heart rate.

In AF, a chaotic electrical activity develops in the walls of the atria, the upper chambers of the heart. This activity overrides the sinus node, a group of cells that have the capacity to produce electrical impulses which contract the heart and help maintain a steady, efficient rhythm to pump blood. In AF that normal, steady rhythm is disrupted. The atria instead begins to quiver with a shallow, irregular but very fast rhythm which can lead to blood pooling and clots.

AF is associated with heart failure, stroke, poor mental health, reduced quality of life and death.

Five facts about AF

  • AF is the most common heart arrhythmia2
  • Risk of stroke increases by 500% for people with AF3
  • At 40, 1 in 4 people are at risk of developing AF4
  • AF-related stroke can be prevented with appropriate anticoagulation therapy5
  • AF can be detected with a simple pulse check5

AF in numbers5,6

  • Every 15 seconds someone suffers from an AF-related stroke
  • About 1.5 million people in the UK have AF and over 16 million worldwide
  • Just in the South West, there is an estimated 18,650 people with undiagnosed Atrial Fibrillation (AF) in the South West7
  • AF and AF-related illness costs the NHS over £2.2 billion each year

Detecting AF

Know Your Pulse

Pulse screening has been proven as the most cost effective strategy in detecting undiagnosed AF in people over 658. In the video below Sir Bruce Keogh, NHS England National Medical Director explains why it is important to know your own pulse.

Learn how to take your pulse with this video below.

Stroke risk calculator

The Atrial Fibrillation Association and Anticoagulation Europe (UK) have put together a stroke risk calculator to raise awareness and help present AF-related stroke.

What can I do to help?

There are many things you can do to help raise awareness for AF. Here at LumiraDx Care Solutions we are hosting a coffee and cake morning to raise awareness about AF in our own staff and their families.

Fundraise and donate

How about hosting an AF awareness activity in your health care centre, community group or workplace? You can download an activity pack from the AF Associations website here.
