概括
三维心声学衍生的右心室喷射率 (RVEF) 是患有缺血和扩张心肌病的患者心脏事件的强有力的预测指标. 这种测量提供了宝贵的风险分层,超出了传统的心声回声学参数.
科学领域:
- 心脏病学 心脏病学
- 心声回声扫描 (Echocardiography) 是一种心声回声扫描.
- 心血管成像 - 心血管成像
背景情况:
- 在缺血性心肌病 (ICM) 和扩张性心肌病 (DCM) 中,三维心声学 (3DE) 衍生的右心室喷射分数 (RVEF) 的预后意义存在有限的数据.
- 评估RV功能对于管理心力衰竭患者至关重要.
研究的目的:
- 在ICM和DCM患者中评估3DE衍生RVEF的预后值.
- 确定RVEF是否提供了超越传统心声回声测量标准的增量预后信息.
主要方法:
- 对120名接受3DE的ICM和107名DCM患者进行了回顾性分析.
- 使用3DE光斑跟踪软件进行RVEF评估.
- 主要终点:结合心脏死亡,心力衰竭住院,心肌梗塞或心室动脉节律失常.
主要成果:
- 在ICM和DCM组 (单变量和多变量分析) 中,RVEF与心脏事件有显著的关联.
- 在对临床因素和LV参数进行调整后,RVEF显示出独立的预后值.
- 卡普兰-梅尔分析显示,基于RVEF和E/e'水平的风险分层显著.
结论:
- 3DE衍生RVEF是ICM和DCM中心脏事件的独立和增量预测器.
- 与E/e'相结合的RVEF允许在这些患者群体中进行详细的风险分层.

Cardiomyopathy 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,...

Cardiomyopathy III: Hypertrophic Cardiomyopathy
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...

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...
