Exchangeable Sodium , Body Potassium , and Body Water in Previously Edematous Cardiac Patients
نویسنده
چکیده
PREVIOUS STUDIES from this laboratory have indicated that cardiac patients who have been successfully treated for congestive heart failure and who have become free from edema have a larger than normal concentration of sodium in their bodies." 2 The suggestion was advanced that part or all of the sodium excess in such patients represented osmotically inactive cation because the patients studied did not have increases in body water comparable to the excess of sodium and because those patients whose body concentration of sodium fell to normal with time did not show a simultaneous loss of body water. The conclusion that previously edematous cardiac subjects have a pool of osmotically inactive cation requires proof that the sodium excess does not merely represent compensation for a deficiency of the principal intracellular cation, potassium. In the studies described above the work of other investigators was cited which made it appear unlikely that potassium depletion was present in the previously edematous cardiac subjects, but no measurements were made of body potassium concentration. The present study was undertaken to evaluate directly the possibility that the excess of exchangeable sodium in previously edematous cardiac sub-

The persistence of high body sodium in previously edematous patients with heart disease.
IN PATIENTS with heart disease the presence of edema is indicative of an increase in extracellular fluid volume. Since the sodium concentration of extracellular fluid is about 140 mEq. per liter, expansion of the extracellular space is accompanied by the accumulation of large quantities of sodium. The magnitude of sodium accumulation has been demonstrated through measurement of total exchangeab...
متن کاملPotassium and sodium distribution in cardiac failure.
1. Total body water, extracellular fluid, total exchangeable potassium and total exchangeable sodium were measured by the multiple isotope-dilution technique in eight patients with congestive cardiac failure. Measurements were made on each patient while in failure and then again after treatment and recovery. 2. Compared with five control subjects in whom the same measurements were made, patient...
متن کاملRegression of body compositional abnormalities of heart failure after intracardiac operations.
SUMMARY Alterations in body composition are present in patients with heart disease and conges-tive heart failure, and additional changes occur acutely after corrective surgery. The reversibility and time course of reversion to normal body composition have not been demonstrated. Nine patients were studied preoperatively and 2 to 4 weeks and 6 to 12 mo postoperatively. Measurements were made, usi...
متن کاملAcute alterations of body composition after open intracardiac operations.
The body composition of patients with heart disease is acutely altered by surgical intervention. Interrelations and causes of the alterations have not been clear. Twenty patients were studied preoperatively and again 2 to 4 days after open intracardiac operations. In nine, measurements were made of the volumes of total body water, extracellular water, plasma, and red cells, and of the amounts o...
