概括
在接受过导管大动脉置换 (TAVR) 的患者中,穿皮冠状动脉干预 (PCI) 的最佳时间仍在争论中. 目前的证据有利于个性化策略,而不是标准化的协议,用于TAVR患者的PCI时间.
科学领域:
- 心脏病学 心脏病学
- 干预心脏病学 干预心脏病学
- 心脏外科手术 心脏外科手术
背景情况:
- 冠状动脉疾病 (CAD) 经常与严重的大动脉狭窄并存,需要通过导管更换大动脉 (TAVR).
- 在TAVR患者中,穿皮冠状动脉干预 (PCI) 的最佳时间是一个复杂的临床决定,没有确立的共识.
- 在TAVR之前,期间或之后平衡PCI的风险和好处是具有挑战性的.
研究的目的:
- 对TAVR患者的各种PCI时间策略的现有证据进行批判性评估.
- 识别患有CAD和严重大动脉狭窄症的患者管理中的不确定性和复杂性.
- 综合来自随机试验和观察性研究的PCI时间相对于TAVR的发现.
主要方法:
- 随机对照试验的审查 (例如,激活,注意-3).
- 对观察性登记数据的分析 (例如REVASC-TAVI,国家再录取数据库).
- 综合了最近关于PCI时间和TAVR结果的元分析的发现.
主要成果:
- 在TAVR前的PCI显示出缺血事件的适度减少,但增加了出血风险.
- 在TAVR前和周围的PCI策略与更高的并发症率有关,没有明显的长期死亡益处.
- 没有任何特定的PCI时间策略表明在减少长期死亡率方面具有明确的优势.
- 个人患者的因素,如解剖学,脆弱性,出血风险和门类型,对于决策至关重要.
结论:
- 建议在TAVR候选人中对PCI时间进行个性化,以患者为中心的方法.
- 标准化的PCI时间协议没有得到当前证据的支持.
- 需要进一步研究风险分层,成像和长期结果,以完善临床指南.

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...

375
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...
