概括
脑卒中是扩张性心肌病 (DCM) 的常见并发症,即使没有心房动 (AF),也经常发生. 在DCM中进行心房重塑可能会独立增加中风风险,需要更好的预防策略.
科学领域:
- 心脏病学 心脏病学
- 神经学 神经学
- 病理学 病理学 病理学
背景情况:
- 扩张性心肌病 (DCM) 是心力衰竭和死亡的主要原因.
- DCM与脑血管事件之间的联系,特别是没有心房动 (AF) 的情况,尚不清楚.
- 这项研究调查了DCM患者中风的患病率和机制.
研究的目的:
- 确定DCM患者中风的患病率,机制和解剖学分布.
- 评估AF和结构改造在中风风险中的作用.
- 在DCM患者中识别潜在的栓塞源.
主要方法:
- 对471名已故DCM患者的回顾性分析.
- 对临床记录,神经成像,尸检和组织病理学数据的审查.
- 使用TOAST标准和出血类别进行中风分类.
主要成果:
- 9.6%的DCM患者患有中风,主要是缺血性.
- 心房动 (AF) 与缺血性中风有关,但在鼻节律中发生了栓塞性中风.
- 脑卒中患者的射出分数较低,心房较大.
结论:
- 脑卒中是DCM的常见并发症,通常是栓塞性,即使没有AF.
- 在DCM中进行心房重塑可能会独立地导致脑血管风险.
- 需要对预防策略进行进一步的研究,包括对高风险的DCM患者的抗凝药,而没有AF.

Cardiomyopathy III: Hypertrophic Cardiomyopathy
411
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...

Cardiomyopathy II: Dilated Cardiomyopathy
470
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,...
