Here is another substudy of the ARIC study published last week. 13,385 patients were followed for 22.4 years. An increase of 9.4% in carbohydrate intake (corresponding to 1 standard deviation) was associated with an 18% lower rate of incident AF.

sleep apnea & AFIB
Half the patients with AFIB also have sleep apnea. Patients with sleep apnea have 4 times the risk of developing atrial fibrillation. How does sleep apnea contribute to AFIB? Potential mechanisms: Changes in intrathoracic pressure during apneic episodes leads to left atrial stretch. Intermittent periods of hypoxemia (low oxygen) and hypercapnia (high carbon dioxide) related…
leaking roof, rotting timber
ARREST AFIB trial Dr. Dennis Lau from Adelaide, Australia made this analogy at the Heart Rhythm Society meeting in San Francisco. He works with Dr. Prasanthan Sanders’ group. This group published one of the seminal studies regarding lifestyle and AFIB – the ARREST AFIB trial. Lifestyle factors that lead to AFIB are like the leaking…
don’t be an Eeyore
Having type D personality is not good your cardiovascular health. Type D personality has 2 traits: Negative affectivity (worry, irritability, gloom). Social inhibition (reticence, lack of self assurance). The prevalence of Type D personality is 21% in the general population and 53% in cardiac patients. Cause or effect? Type D personality affects health related quality of life in…
anxiety, depression & AFIB
Bidirectional relationship There is a complex relationship between depression, anxiety, and AFIB. AFIB can cause depression and anxiety in patients. Depression and anxiety may create an environment that is conducive for the initiation and perpetuation of AFIB. Depression and anxiety affect how patients perceive their illness, and impact healthcare utilization. The presence of depression and…
AFIB & dementia
AFIB may cause cognitive decline via multiple mechanisms: Stroke Multiinfarct dementia due to microinfarcts Microbleeds as a result of anticoagulants Cerebral hypoperfusion – decreased blood flow to the brain Decline in brain volume Beta blockers ??may contribute Catheter ablation for AFIB contributes to micro infarcts (ACE – asymptomatic cerebral emboli) AFIB may be a marker…
AFIB shrinks your brain
Steffansdottir published a study on brain volume in the journal Stroke in 2013. In it she states: AF is associated with smaller brain volume and the association is stronger with increasing burden of the arrhythmia. These findings suggest that AF has a cumulative negative effect on the brain independent of cerebral infarcts. The difference in…
processed food & mortality
A JAMA study from February 2019 showed highly processed food kills you. In 44 551 French adults 45 years or older, a 10% increase in the proportion of ultra-processed food consumption was statistically significantly associated with a 14% higher risk of all-cause mortality. Ultra processed food has high amounts of sugar, salt and saturated animal fat….
accupuncture & AFIB
Of all the non-allopathic (CAM – complementary and alternative) therapies out there, the only one that has been systematically studied is accupuncture. Puncturing of the Neiguan, Shenmen and Xinshu spots has been advocated to treat atrial fibrillation. The best study I can find in a peer reviewed journal is from JCE 2011. 80 patients post…
the wanderer (vagus) & AFIB
The Latin word vagus means “wandering”. The vagus is the longest nerve in the autonomic nervous system in the body. It is a parasympathetic nerve, i.e. it counters the fight or flight response. It innervates the heart, lung and stomach among other things. Just like the famous Nordic wanderer, Odin, the vagus nerve has been attributed with a lot…
