螯合疗法可以治疗心脏病吗?
回答 Francisco Lopez-Jimenez 博士
目前尚不清楚螯合疗法是否能治疗心脏病。
长期以来,螯合疗法一直被用于治疗汞和铅中毒,但尚未证明可以治疗心脏病。当用于治疗心脏病时,此疗法可能引发严重副作用。即便如此,仍有一些患者接受了螯合疗法来治疗心脏病和卒中。
螯合疗法需要每周静脉注射乙二胺四乙酸(EDTA)。每次治疗持续 30 分钟至数小时。
一般来说,该药物在血液中寻找并黏附金属和矿物质。这种作用产生的物质会随尿液排出体外。一些研究人员表示,螯合疗法可以治疗心脏病,因为该药物可能会吸附并清除堵塞动脉的沉积物中的钙。
但使用螯合疗法治疗心脏病仍有争议。
以下是目前已知的情况:
- 螯合疗法评估试验(TACT)提供的证据不足以支持针对心脏病常规使用这种疗法。但试验确实发现,螯合疗法可在一定程度上预防糖尿病患者未来发生心血管事件(例如卒中和心脏病发作)的风险。另一项研究 TACT2 将特别关注糖尿病患者。
- 美国心脏协会和美国心脏病学会表示,尚不确定螯合疗法是否可有效治疗心脏病。
- 美国食品药品管理局还未批准将螯合疗法用于心脏病治疗。
使用螯合疗法治疗心脏病存在已知风险和副作用。最常见的副作用是静脉给药部位灼伤。其他副作用包括发热、头痛、恶心或呕吐。
使用螯合疗法治疗心脏病已报告的罕见但严重并发症包括:
- 血钙水平下降。
- 血压急剧下降。
- 骨髓制造的血细胞数量下降。
- 心力衰竭。
- 肾损伤。
- 死亡。
在尝试使用螯合疗法治疗心脏病之前,请首先向医疗护理团队咨询其益处和风险。
