丹麦哥本哈根消息:丹麦的一项研究结果提示,心脏病学家们可能正在严密注视着用镁作为心肌梗塞(MI)后的治疗制剂。在一项双盲、安慰剂对照试验中,镁输注后MI的死亡率与心律不齐的发生率均减少了一半。但一些美国的心脏病学家对镁在心脏功能中的重要性看法不一致,其中许多人对丹麦研究中关于MI病人血清镁水平迅速下降的基本设想表示怀疑。另一些观察到血清镁水平低有致心律不齐可能的心脏病学者认为,丹麦的论点是有根据的。丹麦的研究者们首先对273例可疑MI病人进行登记,然后当其来到冠心病监护病房时,立即分至静脉输注镁或安慰剂组。他们
Copenhagen, Denmark: A Danish study suggests that cardiologists may be closely watching the use of magnesium as a therapeutic agent after myocardial infarction (MI). In a double-blind, placebo-controlled trial, MI mortality and arrhythmia were reduced by 50% after magnesium infusion. However, some American cardiologists do not agree on the importance of magnesium in cardiac function, and many are skeptical of the Danish study’s basic assumptions about the rapid decline in serum magnesium levels in MI patients. Others have observed that serum magnesium levels are low and cause arrhythmias. Cardiologists believe that the Danish argument is valid. The Danish researchers first registered 273 suspected MI patients and then immediately assigned to intravenous magnesium or placebo when they came to the coronary care unit. they
