关于心脏支架的英语词汇及短语

心脏支架的发展经历了几个阶段，从最初的金属支架到后来的药物洗脱支架（Drug-Eluting Stents, DES），再到最新的生物可吸收支架（Biodegradable Stents）。支架的材料主要包括不锈钢、镍钛合金或钴铬合金。药物洗脱支架的表面涂有防止血管再狭窄的药物，而生物可吸收支架则是设计为在一定时间内被人体吸收，从而减少长期存在的异物反应。

关于心脏支架的英语资料

Coronary artery stents are tubular devices designed to treat narrowed or diseased coronary arteries by keeping them open and facilitating blood flow. Stents are typically made of metal, such as stainless steel, cobalt-chromium alloy, or nitinol (a nickel-titanium alloy). The use of stents has significantly reduced the rate of restenosis (re-narrowing of the artery) after angioplasty.

冠状动脉支架是用于治疗狭窄或病变的冠状动脉的管状装置，通过保持血管开放和促进血流来发挥作用。支架通常由金属制成，如不锈钢、钴铬合金或镍钛合金。使用支架显著降低了血管成形术后动脉再狭窄的发生率。

Stents are delivered to the site of blockage via a catheter and are expanded, either by a balloon or self-expanding, to fit the vessel's diameter. Drug-eluting stents release medication that prevents the buildup of scar tissue inside the stent, reducing the risk of another blockage.

支架通过导管送至阻塞部位，并通过球囊扩张或自扩张来适应血管的直径。药物洗脱支架释放药物，防止支架内形成瘢痕组织，从而降低再次阻塞的风险。

Biodegradable stents are an innovative development in stent technology. They are designed to break down and be absorbed by the body over time, leaving no permanent implant behind. This reduces the long-term risk of complications associated with traditional metal stents.

生物可吸收支架是支架技术中的创新产品。它们的设计是在一定时间内分解并被人体吸收，不会留下永久性的植入物。这减少了与传统金属支架相关的长期并发症风险。

In summary, coronary artery stents play a crucial role in the treatment of coronary artery disease, offering an effective method to maintain the patency of arteries and improve the quality of life for patients with heart conditions.

总之，冠状动脉支架在冠状动脉疾病的治疗中发挥着至关重要的作用，提供了一种有效的方法来维持动脉的通畅性，并改善心脏病患者的生活质量。
