Obesity may increase risk of developing a rapid and irregular heart rate, called atrial fibrillation, which can lead to stroke, heart failure and other complications, says a study of nearly 70,00 patients.

The findings, published in the journal American Journal of Cardiology, showed that people with obesity had a 40 per cent higher chance of developing atrial fibrillation than people without obesity.

The results suggest that for patients with both obesity and atrial fibrillation, losing weight has the potential to help treat and manage their atrial fibrillation, said Andrew Foy, Assistant Professor at Penn State College of Medicine in the US.

“If you have both atrial fibrillation and obesity, treating obesity will go a long way in treating and managing your atrial fibrillation,” Foy said.

“And if you have obesity, and lose weight through diet, exercise, or even surgery, that will help reduce your risk of developing chronic conditions like atrial fibrillation,” he added.

Atrial fibrillation happens when the electrical currents in the heart go haywire and the top chambers of the heart quiver or flutter.

The condition puts patients at a higher risk for developing other heart complications.

While previous research has linked obesity and atrial fibrillation, Foy said he wanted to explore the connection in a larger sample of younger patients.

The researchers followed a group of 67,278 patients — half with obesity and half without — for eight years. The average participant age was 43.8 and nearly 77 per cent were women.

People with obesity are 40 per cent more likely to develop atrial fibrillation, while they are 45 per cent and 51 per cent more likely to develop hypertension or diabetes, respectively, the findings showed.

The researchers also found that people with obesity are almost just as likely to develop atrial fibrillation as people with hypertension or diabetes.  IANS

Obesity Alone Does not Increase Death Risk: Study

Earlier, a study, published in The Lancet Diabetes and Endocrinology journal, found that women with metabolically healthy obesity were at 39 per cent higher risk of cardiovascular disease

Patients who have metabolically healthy obesity but are free from other metabolic risk factors do not have an increased rate of mortality, a new study has found.

Metabolically healthy obesity is a debatable medical condition characterized by obesity which does not produce metabolic complications.

The study, published in the journal Clinical Obesity, showed that unlike dyslipidemia, hypertension and diabetes — each one of which is related to high mortality risk — obesity alone does not pose any threat to life.

“We are showing that individuals with metabolically healthy obesity are actually not at an elevated mortality rate,” said lead author Jennifer Kuk, Associate Professor at the York University in Canada.

“We found that a person of normal weight with no other metabolic risk factors is just as likely to die as the person with obesity and no other risk factors,” Kuk added.

For the study, the research team followed 54,089 men and women from five cohort studies who were categorized as having obesity alone or clustered with a metabolic factor, or elevated glucose, blood pressure or lipids alone or clustered with obesity or another metabolic factor.

The researchers looked at how many people within each group died as compared to those within the normal weight population with no metabolic risk factors.

They found that one out of 20 individuals with obesity had no other metabolic abnormalities.

“This is in contrast with most of the literature and we think this is because most studies have defined metabolic healthy obesity as having up to one metabolic risk factor,” said Kuk.

“This is clearly problematic, as hypertension alone increases your mortality risk and past literature would have called these patients with obesity and hypertension, ‘healthy’. This is likely why most studies have reported that ‘healthy’ obesity is still related with higher mortality risk,” Kuk noted.
