概括
心脏肌瘤是一种常见的良性心脏瘤,由于其位置,经常表现出侵略性的临床行为. 它的"恶性病"是由复发和传播定义的,而不仅仅是组织学.
科学领域:
- 心血管病理学心血管病理学
- 在瘤学瘤学.
- 组织病理学 组织病理学
背景情况:
- 心脏肌瘤是最常见的初级良性心脏瘤,占病例的85%.
- 尽管心肌瘤的形态是良性的,但心肌瘤在血液流中的心脏内位置可能会导致积极的临床表现.
- 心脏肌瘤的组织生成仍在争论中,一些理论认为心脏内膜干细胞起源于心脏内膜干细胞.
研究的目的:
- 审查心脏肌瘤的形态学,临床表现和免疫组织化学参数.
- 探索心脏肌瘤中瘤扩散和复发的机制.
- 为了澄清导致心脏肌瘤恶性瘤的因素.
主要方法:
- 对心脏肌瘤的形态学,临床行为和免疫组织化学的文献综述.
- 对报告病例的分析,重点关注复发,多焦点和转移性传播.
- 检查特征性组织学特征,包括瘤细胞,环状结构,Gamna-Gandy体,化和血栓形成.
主要成果:
- 心脏肌瘤表现出特定的形态特征,包括肌瘤细胞和特征性的二次标志,如Gamna-Gandy体和化.
- 临床行为,标志着复发和多焦点性,尽管有良性组织学,但经常模仿恶性病变.
- 瘤扩散的机制,类似于转移,有助于其侵略性的呈现.
结论:
- 临床行为,而不是组织学,主要定义心脏肌瘤的"恶性".

Structure of Cardiac Muscles
8.2K
Cardiac muscle, or myocardium, is a specialized type of muscle found exclusively in the heart. Its unique structural and functional characteristics enable the heart to perform its vital role of pumping blood throughout the body continuously and rhythmically. The cardiac muscle cells, or cardiomyocytes, possess an endomysium and perimysium but do not have an epimysium.
Compared to skeletal muscles, cardiac muscle cells are small and mostly have a single nucleus. Additionally, they are usually...

Specialized Characteristics of Cardiac Muscles
2.3K
The primary role of cardiac muscles is to propel blood throughout the cardiovascular system. The cardiac muscle cells, or cardiomyocytes, exhibit specialized characteristics that allow them to perform this function.
Cardiac muscle cells are smaller than skeletal muscles, averaging 10–20 mm in diameter and 50–100 mm in length. However, they have large energy demands for continuous contraction and relaxation. This energy is almost exclusively derived from aerobic metabolism of energy...

Mitral Regurgitation II: Clinical features and Diagnostic Tests
1
Mitral regurgitation (MR) is a valvular heart disorder in which the mitral valve fails to close tightly, allowing blood to leak backward into the heart. Understanding the clinical manifestations, assessment, diagnostic findings, and medical management of MR is crucial to effectively managing affected patients.Clinical Manifestations of Mitral RegurgitationMitral regurgitation can be acute or chronic, each presenting differently and requiring different approaches:1. Acute Mitral...

Mitral Valve Prolapse II: Assessment and Management
1
IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...
