まとめ
アントラサイクリンで長期間治療された小児がんの生存者は,心筋病のリスクに直面します. 中枢のエコーカルディオグラフィの評価は高いが不一致な検出率を示し,さらなる調査と予防ケアが必要であることを強調しています.
科学分野:
- 小児腫瘍学
- 心臓病科
- がん の 生き残る 人数
背景:
- 長期にわたる小児がん生存者 (CCS) は,アントラサイクリン誘発性心筋病症のリスクがあります.
- 小児がん患者の心臓機能不全を評価するには,集団研究が必要である.
研究 の 目的:
- 小児神経芽細胞腫や腎芽細胞腫の生存者における心臓機能障害の検出が増加するかどうかを評価する.
- このコホートにおけるアントラサイクリン誘発性心筋病症および関連する危険因子の有病率を決定する.
主な方法:
- 1990年から2012年の間に診断された神経芽細胞腫または腎芽細胞腫の生存者370人を対象とした横断的な研究.
- 参加者はアントラサイクリンを投与され,診断時に18歳未満で,心臓病はありませんでした.
- 質問書,EMAHの心臓検査,レファレンスエコーカルディオグラフィーの評価によって収集されたデータです.
主要な成果:
- 心筋病の発生率は診断後平均9. 1年で6. 3%でした.
- リスク要因には,診断時に5歳未満の年齢とサイクロフォスファミドまたは放射線治療の併用が含まれています.
- EMAHの心臓科医とリファレンスセンターの検出率は高いが,不一致だった.
結論:
- アントラサイクリンで治療された小児がんの生存者では,心臓の遅い効果が一般的です.
- 予防的な検査は 早期診断と治療に不可欠です
- 心筋病の検出の不一致は,患者のケアを最適化するためにさらなる調査を必要とします.

47
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

01:29Cardiomyopathy IV: Restrictive Cardiomyopathy
28
Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...

01:30Cardiomyopathy II: Dilated Cardiomyopathy
22
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,...

01:29Cardiomyopathy VI: Nursing Management
35
Assessment: Nursing management of patients with cardiomyopathy begins with a thorough assessment of the patient's history, including a family history of cardiomyopathy or sudden cardiac death, personal history of heart disease, hypertension, diabetes, and any alcohol consumption or drug use.During the physical examination, assess vital signs, look for signs of heart failure (such as edema, jugular venous distention, and cyanosis), auscultate for abnormal heart sounds (like murmurs and gallops),...

01:25Cardiomyopathy I: Introduction and Classification
51
Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...

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...
