まとめ
ミシガン州では心内膜炎に対する心臓手術が増加している。死亡率は低下したが、患者の特性と医療関連感染症の全体的な傾向は安定していた。
科学分野:
- 心臓血管外科、感染症、公衆衛生
背景:
- 米国では、20年以上にわたり心内膜炎による入院と医療費が増加しています。心内膜炎に対する心臓手術の傾向を理解する必要があります。これらの手術の患者の人口統計学的特性と転帰を特徴づける必要があります。
研究 の 目的:
- 心内膜炎に対する心臓手術の傾向を評価する。患者の人口統計学的特性と転帰を分析する。心内膜炎の原因と手術結果の変化を評価する。
主な方法:
- 遡及的、多施設共同研究で、前向きに収集されたデータを使用しました。ミシガン州で心内膜炎のために弁膜弁手術を受けた成人(2008年~2022年)。患者の特性、心内膜炎の原因、転帰の分析には、Cochran-Armitage傾向検定を使用しました。
主要な成果:
- 心内膜炎に対する弁膜手術の割合は、2008年の3.8%から2022年には8.9%に上昇しました。死亡率は13.6%から9.0%に低下しましたが、統計学的な有意差はありませんでした。院内感染を原因とする心内膜炎の症例に有意な傾向は観察されませんでした。
結論:
- ミシガン州では、心内膜炎に対する弁膜手術が着実に増加しています(2008年~2022年)。術中死亡率、患者リスクプロファイル、院内感染を原因とする心内膜炎の発生率に有意な変化はありませんでした。転帰やリスク要因に有意な変化を伴わずに、心内膜炎に対する手術介入が増加しました。

Endocarditis I: Introduction
362
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Factors Affecting the Risk of Infection
13.2K
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...
