概括
对于接受主动脉置换 (AVR) 的中年患者,生物假肢的生存率与机械假肢相似,但不良事件较少,特别是在55-64岁的人群中.
科学领域:
- 心血管外科心血管外科
- 生物材料科学 生物材料科学
- 公共卫生 公共卫生
背景情况:
- 大动脉置换指南 (AVR) 缺乏关于中年人的假肢选择的共识.
- 这项研究比较了亚洲人口中这一人口群体的机械与生物假肢的长期结果.
研究的目的:
- 在接受AVR的中年患者中,全面比较机械与生物假肢的长期结果.
- 评估死亡率和与假肢相关的主要不良事件的差异.
主要方法:
- 使用台湾国家索赔数据库 (2006-2021) 进行回顾性队列研究.
- 包括1136对45-64岁的患者进行AVR的倾向性得分匹配对.
- 通过使用受限平均存活时间和细分分布危险比率来比较全因死亡率和与假肢相关的主要不良事件,并根据年龄 (45-54岁和55-64岁) 进行分组分析.
主要成果:
- 在整体队列中,生物和机械假肢之间的所有原因死亡率没有显著差异.
- 生物假肢与较少的与假肢相关的重大不良事件有关 (10年RMST差异:0.68年;sHR:0.69).
- 在55-64岁的患者中,生物假肢的存活率相似,但与机械假肢相比,不良事件较少.
结论:
- 生物和机械假肢为接受AVR的中年亚洲患者提供了类似的长期存活率.
- 生物假肢与较低的重大不良事件风险有关,特别是在55-64岁的年龄组.

Aortic Regurgitation III: Medical Management
47
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...
