Thanks to Physicians, Nearly 7,000 Strokes Have Been Prevented in the UK

Nearly 7,000 Strokes have been prevented in the year 2000 to 2016, because of general physicians who have prescribed the eligible atrial fibrillation (A-Fib) patients with blood thinning drugs.

From 2000- 2016, nearly 7.000 strokes have been prevented in the UK. General physicians in the UK have been found to be responsible for this remarkable feat because they have prescribed blood thinning drugs to those who were at a greatest risk of A-Fib. These patients who were at risk were eligible for Atrial fibrillation treatment (A-Fib).

The findings of this study are published in the journal of Heart.

Weight Loss May Reduce Atrial Fibrillation in Obese Individuals
Weight loss may reduce the risk of atrial fibrillation (AF) in obesity sufferers. Obesity and lifestyle factors are associated with progression of atrial fibrillation which is a common heart rhythm disorder.

‘To reduce the risk of stroke by two thirds, patients with atrial fibrillation (A-Fib) are given anticoagulant drugs to prevent blood clotting.’

Researchers from the University of Birmingham's Institute for Applied Health Research analyzed general practice records of five million patients from 2000 to 2016 to find out how many people have a diagnosis of atrial fibrillation and how many are receiving treatment to prevent strokes.

Atrial fibrillation is the most common cause of an irregular heartbeat. Annually, 14 percent of all strokes in the UK are suffered by patients with this condition. To reduce the risk of stroke by around two thirds, patients with atrial fibrillation are given anticoagulant drugs to prevent blood clotting, such as warfarin.

Up until now, there has been little research showing the prevalence and treatment of atrial fibrillation. Now, University of Birmingham research, published in Heart and partly funded by the National Institute for Health Research, has found that the frequency of diagnosis has increased each year between 2000 and 2016 and reached around 1.2 million in 2016. The researchers also found that, in this same 16-year period, the proportion of patients with atrial fibrillation who were being prescribed anticoagulants more than doubled - rising by 40.1% from 35.4% in 2000 to 75.5% in 2016.

Deeper Understanding of Atrial Fibrillation Could Help Lower Risk
Researchers urge a 'deeper dive' into how much AFib a person has, in addition to risk factors and outcomes.

Author Dr. Nicola Adderley said: "We found that in 2000 only 35 percent of people with atrial fibrillation who should be taking anticoagulants were actually prescribed them.

"By 2016, the situation had changed dramatically, and 75 percent were receiving them, which highlights that GPs have become markedly better at not only identifying patients with atrial fibrillation but also at treating these patients.

Apixaban Blood Thinner Safer Than Warfarin in Dialysis Patients With Atrial Fibrillation
Dialysis patients with atrial fibrillation treated with apixaban blood thinner had a significantly lower risk of major bleeding with no difference in stroke found a recent study.

"Furthermore, over the same period, general practitioners also seem to have got better at selecting who should get anticoagulants.

"The drugs are not recommended for a small minority of younger people with atrial fibrillation whose overall risk of stroke is low and prescribing fell from 20 percent to 10 percent in this group."

Does Inflammatory Signaling Play a Causative Role in Atrial Fibrillation?
Inflammatory signals in the heart muscle cells are linked to atrial fibrillation, shows new study.

Senior and corresponding author Professor Tom Marshall said: "This is a success story for NHS general practice.

"Atrial fibrillation causes about 20,000 strokes each year, but general practice is preventing about 7,000.

"The proportion of atrial fibrillation patients getting anticoagulants has continued to increase year on year.

"There are some general practices that do particularly well, and there is every indication that stroke prevention will probably continue to improve."

Author Dr. Krishnarajah Nirantharakumar added: "We hope we will continue to see improvements in stroke prevention within the NHS and more research to investigate the management of atrial fibrillation in UK general practice."
