- 诊断测试 诊断测试 诊断测试
- 血管生理学 血管生理学
背景情况:
- 冠状动脉内皮功能障碍 (CED) 和冠状动脉 (CAS) 是非阻塞性冠状动脉患者心痛的关键原因.
- 使用乙胆 (ACh) 的侵袭性冠状动脉功能测试 (ICFT) 是CED和CAS的标准诊断方法.
- 优化ICFT协议对于准确的诊断和患者管理至关重要.
研究的目的:
- 为了比较3分钟的ACH输液与1分钟的ACH玻尿酸注射方案的诊断产量,用于诊断CED和CAS.
- 评估包括T波异常在CAS诊断标准中的影响.
主要方法:
- 一项对220名患有心痛和非阻塞性冠状动脉的患者进行ICFT的比较研究.
- 患者被分为两组,110人接受了3分钟的ACH输液,110人接受了1分钟的ACH玻尿酸注射.
- 使用多普勒流量测量冠状动脉血流和血管收缩,根据已确定的标准 (COVADIS) 诊断CED和CAS.
主要成果:
- 在3分钟输液和1分钟玻璃注射方案之间,CED的患病率相似 (78%对79%,p=0.869).
- 3分钟的输液方案诊断出CAS的模两可的内型,其频率比1分钟的玻璃注射方案 (24%对44%,p=0.004) 低.

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

Myasthenia Gravis: Diagnostic Tests
831
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.

Depolarizing Blockers: Pharmocokinetics
325
Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...
