Summary
Atrial fibrillation (AF) and obstructive sleep apnea (OSA) are common conditions linked to stroke and mortality. This paper explores their bidirectional relationship and the benefits of screening for both AF and OSA.
Area of Science:
- Cardiology
- Pulmonology
- Neurology
Background:
- Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia.
- Obstructive sleep apnea (OSA) is a common respiratory disorder.
- Both AF and OSA are significant risk factors for ischemic stroke and increased mortality.
Purpose of the Study:
- To summarize the evidence on the bidirectional relationship between AF and OSA.
- To discuss the potential benefits of screening for AF in OSA patients and vice versa.
Main Methods:
- Literature review of studies investigating the link between AF and OSA.
- Analysis of the pathophysiological mechanisms connecting AF and OSA.
- Discussion of clinical implications and screening strategies.
Main Results:
- Evidence supports a bidirectional relationship between AF and OSA.
- Mechanical effects of OSA (e.g., increased afterload, cardiac remodeling) contribute to AF development.
- AF may also influence OSA severity or manifestation.
Conclusions:
- The interplay between AF and OSA necessitates a comprehensive understanding.
- Selective screening for AF in OSA patients and OSA in AF patients may be beneficial.
- Further research is warranted to optimize management strategies for patients with both conditions.

01:21Sleep Apnea
599
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

03:03Amyloid Fibrils
12.1K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

01:13Insufficient Sleep and Sleep Deprivation
963
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

01:11Fibril-associated Collagen
3.4K
Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...

01:22Stages of Sleep
1.5K
Sleep progresses through distinct stages, each characterized by specific brain wave patterns and physiological responses ranging from wakefulness to stages of non-rapid eye movement, known as non-REM, to rapid eye movement, referred to as REM. Understanding these stages helps in recognizing how sleep supports various bodily and cognitive functions.
Before sleep begins, in wakefulness, the brain exhibits primarily beta waves, which are high in frequency and low in amplitude, indicating alertness...
