Transient decrease in serum potassium level during ischemic attack of acute coronary syndrome: paradoxical contribution of plasma glucose level and glycohemoglobin.

ABSTRACT:

Background

Although a decrease in serum potassium level has been suggested to be a fairly common observation in acute coronary syndrome (ACS), there have so far been no definitive reports directly demonstrating the transient potassium decrease (the potassium dip) during ischemic attack of ACS compared to stable phase in individual patients. To understand the pathophysiological significance of the potassium dip, we examined the changes in serum potassium level throughout ischemic attack and evaluated the clinical factors affecting it.

Methods

The degree of the potassium dip during ischemic attack (as indicated by ΔK, ΔK = K at discharge - K on admission) was examined in 311 consecutive patients with ACS who required urgent hospitalization in our institution.
