Abstract
Plasma levels of Zn and albumin were measured for 8 consecutive days in patients suffering chest pain due to myocardial infarction or myocardial ischemia. A substantial diurnal variation was found in both controls and patients. Plasma Zn falls after myocardial infarction reaching the lowest level on day 2, returning to normal by day 8. The lowest plasma Zn levels occur within 48 h of a myocardial infarction, and in some patients herald the development of a serious cardiac arrhythmia. Plasma albumin falls progressively after myocardial infarction, being lowest on day 8. The fall in plasma Zn is not totally explained by the fall in plasma albumin.
