Effect of intravenous metoprolol before hospital admission on chest pain in suspected acute myocardial infarction.

abstract：:The serum chromium in 45 subjects with no clinical evidence of ischemic heart disease was found to be 1.71 parts per billion (ppb) (S.E. +/- 0.14). In 34 patients with a previously documented myocardial infarction, it was 1.84 ppb (S.E. +/- 0.18). The difference was not significant nor was there any difference with ag...
