[Disorders of electrolyte balance in patients with coronary atherosclerosis]
Insights
Patients with chronic ischemic heart disease show early electrolyte imbalances, specifically increased sodium levels, linked to higher cholesterol. This suggests a connection between mineralocorticoid activity and heart disease progression.
Area of Science:
- Cardiology
- Endocrinology
- Biochemistry
Context:
- Investigates electrolyte balance in patients with coronary atherosclerosis.
- Examines the relationship between sodium, potassium, aldosterone, and cholesterol.
- Focuses on early-stage (Stage I and III) coronary atherosclerosis.
Purpose:
- To study the interrelationship between electrolytes (K, Na), aldosterone, and cholesterol in coronary atherosclerosis.
- To identify early markers of electrolyte imbalance in chronic ischemic heart disease.
- To explore the role of mineralocorticoid activity in disease exacerbations.
Summary:
- A study of 30 patients with coronary atherosclerosis revealed electrolyte balance disorders, characterized by increased plasma sodium concentrations (hypernatremia), even in early disease stages.
- This hypernatremia was associated with elevated mineralocorticoid (adrenal) activity during coronary insufficiency exacerbations.
- A positive correlation was observed between blood sodium and cholesterol levels.
Impact:
- Highlights potential early diagnostic indicators for coronary atherosclerosis.
- Suggests a link between sodium retention, mineralocorticoid excess, and hypercholesterolemia in heart disease.
- Provides insights into the pathophysiology of chronic ischemic heart disease.
Abstract:
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.
