Is benefits of magnesium in acute myocardial infarction : timing crucial?
The serum magnesium levels in patients with AMI were lower compared with controls. The administration of intravenous magnesium to patients in the immediate postinfarction period is cardioprotective and decreases the incidence of arrhythmia, pump dysfunction, and death. Thus intravenous magnesium is a safe, effective, and inexpensive modality of treatment in AMI.
The use of radiographic anatomical factors to predict clearance of lower caliceal stones following SWL is an attractive concept. However, based on this study, we feel that these factors do not merit the attention they have attracted. In routine practice, regardless of the radiological anatomy, SWL continues to be the initial treatment option, given its non-invasive nature and ease of administration.
