最近,对镁(Mg~(++))在心脏病中的作用已进行了评价。在动物,镁水平下降可导致心律失常、冠状动脉痉挛、儿茶酚胺诱导的心肌坏死频率增加。在人类,低镁血症常与心律失常的高发性、心机能不全及突发性缺血性心肌死亡有关。急性心肌梗塞(AMI)病人的血清Mg~(++)(S—Mg)既可以下降,亦可正常。AMI后第一个48小时内死亡率和心律失常最高。从AMI病
Recently, the role of magnesium (Mg ~ (++)) in heart disease has been evaluated. In animals, decreased magnesium levels can lead to arrhythmias, coronary spasms, and increased catecholamine-induced myocardial necrosis. In humans, hypomagnesemia often associated with high incidence of arrhythmia, cardiac insufficiency and sudden ischemic myocardial death. Serum Mg ~ (++) (S-Mg) in patients with acute myocardial infarction (AMI) can both decline and also be normal. The first 48 hours after AMI mortality and arrhythmia the highest. From AMI disease
