medical chart review of the 98 ck-mb negative specimens , representing 44 patients , showed that in seven patients with acute myocardial infarction ( mi ) , none would have been missed clinically even if ldis had not been done , and in only one case did ldis play a confirmatory role in a patient who persistently had ck-mb-negative results but who had a strong clinical suspicion of mi .
