概括
结合N终端亲脑尿性 (NT-proBNP) 和左心房应变 (LAS) 的新模型准确地识别了密码性中风 (CS) 患者的心房病变 (AC). 这有助于区分心血管栓塞的原因和个性化治疗.
科学领域:
- 心脏病学 心脏病学
- 神经学 神经学
- 生物标志物研究 生物标志物研究
背景情况:
- 密码性中风 (CS) 是一种异质的疾病,病因不明.
- 心房心脏病变 (AC) 越来越被认为是CS和心房动 (AF) 的重要因素.
- 目前缺乏用于早期和准确的AC识别的诊断工具.
研究的目的:
- 开发和验证一种工具,用于早期和准确地识别CS患者的AC.
- 在CS中区分心血管栓塞和非心血管栓塞性中风病因.
- 为CS患者指导个性化临床管理策略.
主要方法:
- 一项前性研究,包括因AF (CES-AF),非心血管血栓性中风 (NCES) 和CS引起的心血管血栓性中风的患者.
- 通过斑点跟踪心声学和血清生物标志物 (NT-proBNP) 评估左心房应变 (LAS).
- 使用ROC分析开发后勤回归模型,以预测CS患者的AC概率.
主要成果:
- 在收缩期间NT-proBNP水平 (≥469 pg/mL) 和双平面LAS (LASct) (≥-10.2%) 的组合显示了AC识别的高精度 (AUC=0.995).
- 大约30%的CS患者表现出预测的AC概率>0.5.5.
- 预测高AC概率的CS患者年龄较大,经历了更严重的中风,并且在随访期间有更高的AF发病率.
结论:
- NT-proBNP水平和双平面LASct作为AC的高度敏感和特定的生物标志物.
- 开发的多参数模型使得CS患者的个性化AC概率估计成为可能.
- 这种模型可以帮助区分心血管与非心血管病因,并为个性化管理提供信息.

Esophageal Perforation-II: Clinical Manifestations and Management
717
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.

Barrett Esophagus-II: Clinical Manifestations and Management
1.1K
Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...

Esophageal Varices-II: Clinical Features and Management
568
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.

Gastritis III: Clinical Manifestations and Management
1.2K
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

Acute Pancreatitis II: Clinical Manifestations and Management
854
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...
