まとめ
左心室補助器 (LVAD) の患者における大動脈根栓塞 (ART) は,認識不足である可能性があります. しかし,この研究では,ARTがLVAD患者の死亡率や主要な有害事象に有意な影響を与えないことが判明しました.
科学分野:
- 心血管医学 心血管医学
- 医療機器 医療機器について
- トロンボシス研究研究
背景:
- 大動脈根栓塞 (ART) は,左心室補助器具 (LVAD) を使用している患者の既知の合併症です.
- ARTに関連する臨床結果を理解することは,LVAD患者の管理に不可欠です.
- ARTは診断不足になり,心臓や末臓に有害な影響を及ぼす可能性があります.
研究 の 目的:
- 左心室補助器 (LVAD) を投与した後に大動脈根栓塞 (ART) を発症した患者の臨床結果を評価する.
- LVAD集団におけるARTと有害事象の関連性を決定する.
主な方法:
- 2020年1月から2022年3月までの間に移植された成人LVAD患者の遡及分析.
- 術前データと退院後の複合アウトカムを,ART患者と無患者の比較.
- 総合的なアウトカムには,脳血管疾患,ポンプ血栓症,心筋梗塞,栓塞性疾患,出血,右心房不全,死亡率が含まれていました.
主要な成果:
- 44人のLVAD患者のうち,20人 (45%) が退院後ARTを発症し,中位59日後に血栓が形成されました.
- 主要な血栓形成部位は,ART症例の50%で冠動脈以外の頂点であった.
- グループ間の複合アウトカム (p=0.276),死亡率 (p=0.814),出血 (p=0.808),またはRV不全 (p=0.197) に関する有意な差異は観察されなかった.
結論:
- 大動脈根栓塞 (ART) は,LVAD患者で頻繁に見られる症状です.
- その発生にもかかわらず,ARTは,このコホートにおける死亡率または主要な有害事象を有意に増加させなかった.
- 重要なART関連の合併症がない場合でも,LVAD患者の緊密なモニタリングと管理は不可欠です.

Patient-centered Care

Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
354
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Prevalence and Incidence

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...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests
568
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Venous Thrombosis I: Introduction

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Lattice Centering and Coordination Number
12.2K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.
