- 遗传学 是一个遗传学.
- 分子生物学分子生物学
背景情况:
- 节律失调的腹腔心肌病 (AVC) 是一种遗传性心肌疾病,与心脏体组件的遗传缺陷有关.
- 德斯莫格林-2 (DSG-2) 基因的突变与AVC的发病有关.
研究的目的:
- 报告一个独特的DSG-2相关的AVC病例,其临床和成像特征模仿心脏沙尔科毒症.
- 强调基因测试在诊断具有炎症特征的心肌病症的重要性.
主要方法:
- 一名49岁的男性患有不补偿性心力衰竭和心室节律失常的临床表现.
- 心脏磁共振成像 (MRI) 和18F-氧葡萄糖-正子发射断层扫描 (FDG-PET) 扫描以评估心脏功能和炎症.
- 基因测试使用扩展心肌病/AVC基因组.
主要成果:
- 最初的成像和对类固醇的反应表明心脏型发病症,但随后的遗传测试发现了致病性DSG-2变种.

Imaging Studies for Cardiovascular System IV: CMRI
541
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Acute Coronary Syndrome III: Diagnostic Studies
495
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Heart Failure I: Introduction
1.7K
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 IV: Classification and Diagnostic Evaluation
1.0K
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...

Cardiomyopathy II: Dilated Cardiomyopathy
790
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Cardiomyopathy V: Interprofessional Care
753
Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...
