概括
三维斑点跟踪回声心脏图 (3DSTE) 能够有效地检测乳腺癌患者的早期左心室功能障碍,这些患者正在接受环素化疗. 来自3DSTE的心肌综合指数 (MCI) 是这种化疗引起的心脏损伤的最敏感指标.
科学领域:
- 心脏病学 心脏病学
- 在瘤学瘤学.
- 医疗成像医学成像
背景情况:
- 人环素化疗对于乳腺癌治疗至关重要,但可能导致心脏毒性.
- 早期发现左心室功能障碍对于管理化疗引起的心脏损伤至关重要.
- 传统的心声回声可能没有足够的灵敏度来早期检测微妙的功能变化.
研究的目的:
- 评估3DSTE在评估乳腺癌患者的左心室 (LV) 功能变化的有用性.
- 为了比较3DSTE衍生参数的灵敏度,包括心肌综合指数 (MCI),与传统方法和血清心脏托邦素T (cTnT) 进行比较.
主要方法:
- 对接受 antracycline 化疗的 30 名乳腺癌患者的回顾性分析.
- 在基线时测量血清cTnT,在1次和4次化疗周期后.
- 获取常规心声回声和3DSTE参数,包括LV全球菌株和扭曲.
- 计算MCI和ROC曲线分析用于参数评估.
主要成果:
- 3DSTE参数在化疗时间点 (P < .001) 中发生显著变化,表明LV功能障碍进展.
- 在MCI中,最显著的下降是随着Anthracycline剂量增加而出现的.
- 在4个循环后,在9名患者中观察到血清cTnT升高.
- 在ROC分析中,MCI被确定为最敏感的参数 (AUC=0.799,灵敏度=77.80%,特异性=90.50%).
结论:
- 3DSTE是早期检测左心室功能障碍的有价值的工具,用于治疗乳腺癌患者的左心室功能障碍.
- 来自3DSTE的心肌综合指数 (MCI) 是识别化疗诱导心脏毒性的最敏感的成像生物标志物.

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...

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
