CHF causes a decrease in cardiac output and circulating blood volume , which in turn triggers a compensatory response aimed at preserving blood pressure. This stimulates the body to retain both water and sodium. In addition, in CHF sympathetic stimulation is increased, causing renal vasoconstriction.
Why does sodium increase in heart failure?
Excessive sodium intake is linked to water retention, and it is also a risk factor for high blood pressure . Both excessive sodium intake and high blood pressure are major risk factors for developing heart failure, and for causing complications in those with existing heart failure.
Why is sodium low in heart failure?
Hyponatremia in patients with CHF is primarily caused by increased activity of arginine vasopressin (AVP) . AVP increases free-water reabsorption in the renal collecting ducts, increasing blood volume and diluting plasma sodium concentrations.
Is sodium high or low in heart failure?
Hyponatremia or low serum sodium level is typically defined as a serum sodium concentration of <135 mEq/L and is one of the most common biochemical disorders featured in heart failure patients, with a prevalence close to 25% [2–4]. HF affects cardiac output by either decreasing heart rate or reducing the stroke volume.
What happens to sodium in heart failure?
At an early stage of congestive heart failure, retention of sodium and water by the kidney causes expansion of extracellular fluid volume and peripheral edema , but not hyponatremia.

Is salt good for heart patients?

What food is good for heart failure?
Choose foods that are low in salt, such as fresh meats, poultry, fish, dry and fresh legumes, eggs, milk and yogurt . Plain rice, pasta and oatmeal are good low-sodium choices. However, the sodium content can increase if salt or other high-sodium ingredients are added during their preparation.
