According to the study, irregular heart beats can lead to dementia



According to one study, a fast, irregular heartbeat can increase a person's risk of dementia.

Patients with atrial fibrillation have been diagnosed with an up to 52 percent higher likelihood of a disorder that deprives memory over a seven-year period.

According to scientists, AF can cause those affected to unknowingly experience "mini-strokes" that alter the blood vessels in their brains.

Damaged or blocked vessels can prevent oxygen-rich blood from entering areas of the vital organ and causing brain cells to die.

Over time, a person's memory, thinking, or language skills could be compromised, South Korean experts warned.

  A fast, irregular heartbeat can increase a person's risk of dementia.

A Fast, Irregular Heartbeat Can Become a Person's Dementia Risk (Inventory)

The investigation was conducted by the Yonsei University in Seoul under the direction of Drs. Boyoung Joung, an assistant professor at the Department of Cardiology.

"An irregular heartbeat increased the risk of Alzheimer's, the most common form of dementia, by 31 percent."

He added that the results published in the European Heart Journal also showed AF. The risk of vascular dementia has more than

This form of dementia occurs when the condition is caused by a decreased blood flow to the brain.

Dr. A stroke from our calculations.

"This means that in the general population there is an additional 1.4 People with dementia suffer from dementia per 100 people if they are diagnosed with atrial fibrillation. "

" However, in people who developed AF and who took oral anticoagulants, the risk was subsequently reduced by 40 percent, "Dr. Joung added.

New findings increasingly associate AF with cognitive decline, which is why this was unclear.

In the largest study of its kind in 2004, researchers analyzed 262,611 people over 60 who did not suffer from AF or dementia

Co-author Professor Gregory Lip, Chair of Cardiovascular Medicine at the University of Liverpool, said: "With these big numbers, we can be sure of our results."

Participants who were part of Korea The National Health Insurance Service senior study was followed from 2005 to 2012.

During the seven-year study, 10,435 participants developed VHF, of which 2,522 (24 percent) were diagnosed with dementia. [19659002] This compares to the 36,322 (14 percent) participants who suffered from memory-robbing disease but remained AF-free. However, the 3,092 AF patients who took anti-coagulants or blood thinners were 39 percent less likely to develop dementia.

[19659002] "Physicians should think carefully and be prepared to prescribe anticoagulants for atrial fibrillation patients to prevent dementia," said Professor Lip.

WHAT IS ATRIALFIBRILLATION?

Atrial fibrillation is a heart disease that causes an irregular and often unusually fast heart rate.

A normal heart rate should be regular and between 60 and 100 beats per minute when you rest.

You can measure your heart rate by feeling the pulse in your neck or wrist.

In atrial fibrillation, the heart rate is irregular and can sometimes be very fast. In some cases, it can be considerably higher than 100 beats per minute.

This can lead to problems such as dizziness, shortness of breath and tiredness.

Atrial fibrillation is the most common cardiac arrhythmia and affects about 1 million people in the UK.

It may affect adults of all ages but is more common in the elderly. It affects about 7 out of 100 people over the age of 65.

You may be aware of noticeable palpitations in which your heart feels as if it is beating, knocking, or fluttering irregularly, often for a few seconds, or in some cases for a few minutes ,

You should make an appointment with your family doctor if:

  • you notice a sudden change in your heartbeat
  • your heart rate is constantly below 60 or above 100 (especially if you experience other symptoms). Atrial fibrillation, such as dizziness and shortness of breath)
  • In case of chest pain, consult your GP as soon as possible.

Warfarin is a "normal" anticoagulant, while examples of non-vitamin K versions include dabigatran, rivaroxaban, apixaban, and edoxaban.

Professor Joung added: "It is expected that non-vitamin K anticoagulants, which have a significantly lower risk of cerebral hemorrhage than warfarin, are better in terms of their effectiveness from dementia prevention."

An ongoing study is evaluating the efficacy of non-vitamin K anticoagulants in the prevention of dementia.

Future studies should examine whether catheter ablation has the same effect as the researchers claim.

A catheter is passed through blood vessels to the heart to stop abnormal electrical pathways in the cardiovascular tissue.

The researchers emphasize that their findings suggest only an association between AF and dementia, not that the former causes the latter.

They did not differentiate between sporadic and consistent atrial fibrillation.

Although atrial fibrillation usually causes symptoms, those affected can not know that they have it.

An electrocardiogram was used to determine participants' cardiac rhythm and electrical activity. However, the researchers believe there is a possibility that some AF cases have not been diagnosed.

It is also unclear whether AF treatment to reduce participants contributed to dementia risk. The researchers hope to investigate this in future studies.

A healthy heart typically strikes 60 to 100 times a minute at rest.

However, AF results in an inconsistent frequency, sometimes well over 100 every 60 seconds.

AF affects more than half of those over 80 years old and is expected to increase with increasing population live longer.

Many sufferers experience only palpitations, fatigue and shortness of breath. AF also increases the risk of stroke, heart failure and hospitalization.

According to the Alzheimer's Society, 850,000 people in the UK alone are affected by dementia.

Around 15 percent of people over the age of 70 in the United States suffer from memory impairment, statistics from the Clear Thoughts Foundation show.
