主动脉瓣钙化是正在发展心脏病的体征吗?
回答 Francisco Lopez-Jimenez 博士
主动脉瓣位于左下心脏腔室和通向身体的主要动脉(主动脉)之间。主动脉瓣钙化是主动脉瓣上形成钙沉积的医疗状况。这些沉积可能会导致瓣膜开口变窄。若严重变窄,可能会减少流经主动脉瓣的血流,也即是主动脉瓣狭窄。
主动脉瓣钙化可能是心脏病的早期体征,即使没有其他任何心脏病症状。
钙化和狭窄通常影响老年人。若发生在年龄较小者身上,则通常是由以下原因所引起:
- 出生时即存在心脏缺陷(先天性心脏缺陷)
- 其他疾病,例如肾衰竭
主动脉瓣硬化(瓣膜增厚和僵硬以及轻度主动脉钙化)通常不会导致严重的心脏问题。但需要定期检查,以确保病情不会恶化。如果瓣膜变得严重狭窄(瓣膜狭窄),可能需要进行主动脉瓣置换术。
