まとめ
冠動脈カルシウムスコアが0以上であることは,アントラサイクリンがん治療を受けている患者の心臓機能不全の重要な危険因子です. HFA-ICOSリスクスコアは,がん治療に関連する心臓機能障害の発生率とも相関しています.
科学分野:
- 心臓腫瘍学
- 心血管イメージング
- 腫瘍学
背景:
- がん治療による心血管毒性の危険因子と動脈硬化のリスク因子はしばしば重なり合っている.
- 現在のガイドラインでは,治療前のリスク評価のために,常規の冠動脈カルシウムスコアを推奨していません.
- アントラサイクリン化学療法には心臓毒性の重大なリスクがあります.
研究 の 目的:
- 冠動脈カルシウム (CAC) スコアががん治療に関連する心機能障害 (CTRCD) に与える影響を予測的に評価する.
- アントラサイクリン治療を受けている中等から高リスクの患者のCTRCDを評価する.
- アントラサイクリンで治療された患者のCACスコアの予測値を決定する.
主な方法:
- リスク因子評価,実験室検査,全長ストレング (GLS) でのエコーカルジオグラフィー,CACスコアリングによる冠動脈トモグラフィーを含む前向きな研究.
- アントラサイクリン治療を受ける資格のある患者80人が登録され,77人が平均11. 5ヶ月間追跡された.
- 患者は,HFA- ICOSリスクスコアによって中等リスク (MR) と高リスク (HR) のカテゴリーに分けられた.
主要な成果:
- CACスコア > 0は,高齢患者およびHRグループ (p < 0. 001) の患者でより多く見られ,高血圧,高脂血症,CKD,NT-proBNPレベルと相関していました.
- 追跡期間中,CTRCDは49. 4% (軽度),9. 1% (中度),3. 9% (重度) の患者で発生しました.
- CTRCDはHR患者 (p=0. 005) とCACスコア > 0 (p=0. 036) の患者でより一般的であった. 多変量分析により,CACスコアはCTRCDの独立予測値として0と確認された.
結論:
- 冠動脈カルシウムスコアは,中等リスクおよび高リスクの患者において,アントラサイクリンベースのがん治療中に心機能障害を発症する重要な独立リスク因子です.
- HFA- ICOSリスクスコアは,CTRCDの発生率と強い相関を示し,アントラサイクリンを投与する患者の心臓毒性の予測におけるその使用を検証した.

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...
