*Improvement of symptoms but not survival
* [[ARNI]], [[MRAs]], and [[SGLT2 inhibitors]] may also possess [[diuretic]] properties.
**In fact higher doses of lasix are associated with higher mortality, likely as a results of higher doses being a marker of more severe disease.

* [[Patients]] should be trained to self-adjust their [[diuretic]] dose based on monitoring of symptoms/signs of [[congestion]] and daily [[weight]] measurements.


====Thiazide Diuretics====
* Inhibit the Na+/Cl- co transporter in the distal convoluted tube.
* Although [[thiazide]] [[diuretics]] are effective in mild [[heart failure]] they are usually inadequate for the treatment of severe [[heart failure]].
* [[Thiazide]] [[diuretics]] have also been associative with [[hyponatremia]].


====Loop Diuretics====
* Agents in this class include [[Furosemide]] or [[lasix]], [[bumetanide]], [[ethacrynic acid]] and [[torsemide]].
* Loop diuretics inhibit the Na+/K+/Cl- transporter.
* Fluid retention usually responds best to [[furosemide]] (Lasix)
** If there is no response to the initial  dose then it can be increased by at least 50%.
* The maintenance dose of the [[diuretics]] is lower than that required to initiate diuresis, and for lasix it is usually 10 to 20 mg per day.
* The patient should be told to return to their physician in the next three to seven days after initiation for further assessment including assessment of their [[potassium]] concentration.
* Weight loss should not exceed 1 to 2 pounds/day.
* If the patient gains more than two pounds and they are instructed to double the dose of their loop diuretic.
* Once the baseline weight has been re-established than they can resume their previous status.
* Higher lasix doses are associated with higher mortality, likely as a surrogate of disease severity rather than part of a causal pathway.
* Intermittent use of [[metolazone]] into dose of 2.5 or 5 mg can be given if the patient is refractory to [[furosemide]] Lasix. [[Metolazone]] should be given in the inpatient setting.

Overview

Diuretics reduce circulating volume, improve symptoms and are a mainstay of therapy for congestive heart failure. While these agents improve symptoms, they have not been associated with a reduction in mortality and are associated with electrolyte imbalances.

Diuretics

Diuretics


Potassium Sparing Diuretics

  • The role of potassium sparing diuretics such as spironolactone (Aldactone), amiloride, or triamterene remains the subject of controversy.
  • Spironolactone is currently recommended only as third line therapy for congestive heart failure.
  • These agents inhibit Na reabsorbtion and Potassium secretion in the distal convoluted tubule and cortical collecting duct.
  • Their significant side effect is hyperkalemia.
  • Extreme caution is necessary when adding a potassium sparing agent to the regiment that includes ACE inhibitors particularly when diabetes or renal disease is present because the patient can become hyperkalemic.

Complications

Class I

1. Diuretics should be used for relief of symptoms due to volume overload in patients with HFpEF. (Class I, Level of Evidence: B)
