概括
左心房应变 (LAPS) 在接受TAVI的严重大动脉狭窄患者中受损,并预测长期死亡率. 拉普斯有助于风险分层,以便及时更换门.
科学领域:
- 心脏病学 心脏病学
- 心声回声图 (Echocardiography) 是一种心声回声图.
- 心脏外科手术 心脏外科手术
背景情况:
- 严重的大动脉狭窄 (AS) 带来了重大风险.
- 过导管大动脉植入 (TAVI) 是一种常见的治疗方法.
- 左心房 (LA) 功能评估对于预后至关重要.
研究的目的:
- 在接受TAVI的严重AS患者中调查左心房储应变 (LARS) 和应变 (LAPS).
- 为了确定LA菌株参数与长期存活率的关联.
- 评估 LAPS 在 TAVI 后死亡率的预测值.
主要方法:
- 在198名接受TAVI治疗的重症AS患者中使用了斑点跟踪回声心脏学.

01:30Cardiomyopathy II: Dilated Cardiomyopathy
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 V: Interprofessional Care
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...
