概括
心脏磁共振成像 (CMR) 和内心肌组织活检 (EMB) 在心力衰竭的婴儿中显示炎症,但区分原因仍然具有挑战性. 包括EMB,CMR和基因检测在内的综合方法对于准确的诊断至关重要.
科学领域:
- 儿童心脏病学 儿童心脏病学
- 心血管成像 - 心血管成像
- 炎症性心肌病 炎症性心肌病
背景情况:
- 内心肌活检 (EMB) 是心肌炎的黄金标准,但缺乏普遍接受.
- 2018年路易斯湖标准 (LLC) 在儿科患者的诊断效用需要进一步定义.
研究的目的:
- 为了评估心脏磁共振成像 (CMR) 与新发性心力衰竭的婴儿的定量映射.
- 评估EMB和CMR在检测炎症性心肌病并确定其病因方面的能力.
主要方法:
- 对接受CMR的婴儿进行前性分析,包括组织映射,EMB和遗传检测.
- 根据具有负遗传的炎症性心肌病 (疑似心肌炎) 与积极的遗传 (疑似扩张性心肌病) 进行分类.
- 分析了临床表现,心声学,素,NT-proBNP,EMB发现 (单核细胞,T淋巴细胞) 和CMR (包括晚期加多增强和组织映射).
主要成果:
- 所有患者都符合炎症性心肌病的EMB标准;在各组之间发现了炎症和的显著差异.
- 较高的热素水平与炎症增加相关.
- 无论是经典的CMR标准还是2018年易斯湖标准都没有区分这些群体;只有晚期的加多增强显示与心肌炎有关,而其他CMR参数和组织映射则没有.
- 在EMB检测到的炎症和CMR发现之间没有观察到相关性.
结论:
- 婴儿心脏功能障碍可能源于遗传因素或感染,通常涉及炎症.
- 虽然CMR对炎症敏感,但它可能无法区分心肌炎和婴儿扩张性心肌病.
- 一个全面的诊断策略是必不可少的,整合EMB (T淋巴细胞,瘤),CMR (LGE,组织映射),病毒检测,热素水平和遗传检测.

Heart Failure IV: Classification and Diagnostic Evaluation
18
Heart failure can be classified in various ways, with the most common classifications based on physical activity limitations, disease progression, severity, and treatment strategies.The Functional Classification of Heart Failure divides patients into four categories based on physical activity limitation due to symptom burden.Class I: Patients in this class have cardiac disease but no physical activity limitations. Ordinary activities like walking, climbing stairs, or routine tasks do not cause...

Pathophysiology of Heart Failure
1.6K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Heart Failure I: Introduction
14
Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...

Heart Failure II: Pathophysiology
14
Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Heart Failure III: Clinical Manifestations
20
Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
37
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
