まとめ
ストレスに関連した心房細動 (AF) は一般的ですが,十分に治療されていません. 原発性AFに類似したリスクにもかかわらず,ストレス因子に関連したAFの患者は,抗凝固剤を少なく受け,有害事象のリスクが増加します.
科学分野:
- 心臓病学 心臓病学
- 内科内科は,内科の内科である.
- 公衆衛生は公衆衛生である.
背景:
- ストレスに関連した心房細動 (AF) は,しばしば診断されるが,理解は不十分である.
- リスク要因,結果,およびストレス因子に関連したAFの管理については,さらなる調査が必要です.
研究 の 目的:
- リスク要因,アウトカム,およびストレス因子に関連したAFの管理を分析する.
- 大規模なプライマリーケア集団におけるストレッサー関連AFとプライマリーAFを比較する.
主な方法:
- VITAL-AFクラスターランダム化試験 (N=30,265) のデータの分析.
- 臨床リスク因子,インシデントAF (ストレスに関連した対主),および経口抗凝固剤の開始の比較.
- コックス比例リスクモデルは,大出血,脳卒中,死亡率の複合エンドポイントを評価した.
主要な成果:
- 発生したAF症例のほぼ3分の1 (29%) はストレス要因に関連していた.
- 臨床的リスク要因は,AFの両方のタイプに類似した関連性を示しました.
- 経口抗凝固剤の投与開始は,ストレス因子に関連したAF (56%) とプライマリAF (75%) の間で著しく低かった.
- ストレスに関連したAFは,AFのないものと比較して,有害な結果のリスクが高いことを示した (HR,6.13).
結論:
- ストレスに関連したAFは,高い有害事象発生率を持つ重要な臨床実体です.
- ストレス因子に関連したAFにおける抗凝固剤の使用量の低下は,さらなる調査と最適化された管理戦略を正当化します.
- 将来の研究は,ストレス要因に関連したAFの予防,監視,治療に焦点を当てるべきである.

Factors Affecting the Risk of Infection
13.8K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Amyloid Fibrils
12.0K
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,...

Types of Stressors
707
A stressor is any event, condition, or stimulus that triggers stress and causes a physical or psychological response in the body. Stressors can be categorized into three main types: catastrophes; significant life changes; and daily hassles, including social stress. Each can be detrimental to physical and mental well-being.
Catastrophes
Catastrophes refer to large-scale, unpredictable events that create overwhelming stress and a sense of threat. Examples include natural disasters like...

Prevalence and Incidence
1.9K
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Introduction to Vital Signs
8.7K
Vital signs are physiological measurements that help key into the status of the body's essential functions. These include body temperature, pulse rate, respiratory rate, and blood pressure, commonly abbreviated as T, P, R, and BP. Some healthcare settings also consider oxygen saturation (SpO2) and, in specific contexts, pain and level of consciousness as additional vital signs.
Vital signs help healthcare professionals assess an individual's well-being and detect any functional changes...
