CONTEXT Clinical practice guidelines recommend maintaining serum potassium levels between 4.0 and 5.0 mEq/L in patients with acute myocardial infarction (AMI). These guidelines are based on small studies that associated low potassium levels with ventricular arrhythmias in the pre-β-blocker and prereperfusion era. Current studies examining the relationship between potassium levels and mortality ...

Hypokalemia is a metabolic/endocrine disorder that is characterized by a plasma potassium level of less than 3.5 mEq/L. A serum potassium level that is less than 2.5 mEq/L leads to life threatening scenarios of arrhythmias and muscle paralysis. A normal level of potassium is necessary to maintain a charge difference between intracellular and extracellular environments which is the integral mech...

In recent years it has become increasingly evident that a depletion of body potassium may occur in a number of conditions. The relationship of a fall in the serum potassium to the attacks of -familial periodic paralysis is well known. Potassium deficiency has also been found in infantile diarrhoea, intestinal obstruction with vomiting, sprue, renal insufficiency, diabetic coma, Addison's diseas...

Sixty patients with a first acute myocardial infarction and no current treatment with cardioactive drugs were included in a prospective study of the relationship between serum potassium concentration and the early occurrence of ventricular tachycardia and premature ventricular contractions (PVCs). Serum potassium level (range 2.5 to 5 mmol/liter) was estimated 3.8 +/- 2.5 hr (mean +/- SD) after...

INTRODUCTION Unfractionated (UF) heparin is the most common anticoagulant used during hemodialysis. Failure of the kidneys to excrete potassium as well as heparin-induced reduction of aldosterone synthesis put hemodialysis patients at risk of hyperkalemia. It has not yet been clearly known whether hyperkalemia is also induced by low-molecular-weight (LMW) heparins. This study aimed to evaluate ...

Hypokalemia is a fatal metabolic, pathological and induced disorder of Potassium, manifested by low serum levels generally encountered in lactating animals during thermal-stress. Currently Potassium given normal saline intravenously very slowly. This method costly, risky laborious. To study the effect oral administration 12 g elemental 200 ml Propylene glycol orally hypokalemic cows. After esti...

A 52-year-old woman was referred to our hospital due to chronic renal failure with a 10-year history of hypertension. We found polycystic kidney disease, pulmonary tuberculosis and an aldosterone-producing adrenocortical mass. At this time, her serum potassium level and blood pressure were within the normal range. She refused hemodialysis and then was hospitalized because of uremic encephalopat...

migraine is one of the common varieties of headache. it involves 4 to 6 percent of men and 13 to 16 percent of women under 30 years in more than 80% of cases. some studies have shown that in 50% of patients serum magnesium level decreases during attacks of headache and using magnesium tablets and intravenous magnesium sulfate is more effective for treatment of migraine attack, than placebo. thi...

The purpose of this study was to identify food sources for major minerals such as calcium (Ca), phosphorus (P), sodium (Na) and potassium (K), and to evaluate the relationship between dietary intake of these minerals and serum lipids in healthy Korean adults. A total of 132 healthy men and women completed a physical examination and dietary record and provided blood samples for lipid profile ana...
