[Disorders of electrolyte balance in patients with coronary atherosclerosis]. / Narusheniia elektrolitnogo ravnovesiia u bol'nykh koronarnym aterosklerozom

In 30 patients with stage I and III coronary atherosclerosis the interrelationship between K and Na content in blood and erythrocytes, daily urine excretion of aldosterone and blood level of cholesterol was studied. It was established that in patients with chronic ischaemic heart disease the electrolyte balance disorders manifested themselves on the early stages of the disease in increased plasma Na concentrations. The hypernatremia in such cases was traced against the background of an elevated mineral-corticoid activity of the adrenal glands during exacerbations of coronary insufficiency. A positive correlation was revealed between the blood levels of Na and cholesterol.
