Mineralocorticoid Receptor Antagonists
The competitive antagonists of the aldosterone (or mineralocorticoid) receptor, spironolactone and eplerenone, reduce mortality and hospitalizations in patients with New York Heart Association (NYHA) functional class II to IV HFrEF and in those with an LVEF <40% after an acute myocardial infarction. 69–71 The effect of these agents on quality of life and exercise tolerance has not been well documented. Treatment should begin with low doses, uptitrated slowly to a maximum dose of spironolactone 25 mg daily and eplerenone 50 mg daily, with the serum potassium level maintained between 4 and 5 mEq/L. For SNF residents with HFrEF, NYHA functional class II to IV symptoms despite appropriate medical therapy, and estimated glomerular filtration rate ?30-59 mL/min/1.73 m 2 , initiation of mineralocorticoid receptor antagonist therapy is reasonable, so long as close monitoring can be ensured. In patients who do not fulfill these criteria, the value of mineralocorticoid receptor antagonists is unproven and the risks may outweigh the benefits; therefore, use of these agents in such cases should probably be avoided.
Hydralazine/Nitrates
The mixture off hydralazine and oral nitrates decrease mortality inside notice-identified black customers with HFrEF when administered combined with basic HF medication. At exactly the same time, the blend try a fair replacement for ACEIs and you may ARBs within the clients which have contraindications or intolerance to renin-angiotensin program antagonists that will be taken since adjunctive cures during the clients which have complex HF periods even with treatment with old-fashioned agents. Pair analysis come toward entry to hydralazine/nitrates for the clients ?75 yrs . old. Side effects out-of hydralazine (worries, gastrointestinal disruptions, tremors, angina) and you may nitrates (headaches, dizziness, flushing) was seemingly popular. This combination basically should be thought about to own people that happen to be currently finding ?-blockers. Starting dosages is hydralazine 10 to twenty-five mg and you will isosorbide dinitrate ten milligrams, per applied 3 times daily, with titration so you’re able to limit dosage off hydralazine 75 so you’re able to 100 milligrams three times each and every day and you can isosorbide dinitrate 29 in order to 40 milligrams three times everyday.
Digoxin
In the Digoxin Investigation Group (DIG) trial, digoxin had no effect on mortality but significantly reduced HF hospitalization in both younger and older HFrEF patients. Subsequent post hoc analyses of the DIG trial data suggest that low-dose digoxin, as defined by a serum digoxin concentration <1.0 ng/mL, may be associated with improved survival in patients with HFrEF and NYHA functional class II to III symptoms. 72 Although digoxin was equally safe in younger and older adults in DIG, there are few data on octogenarians and SNF residents. As in most randomized controlled trials of HF, only 5% of the DIG participants were ?80 years of age, and only 11 patients were ?90 years of age.
Newest recommendations suggest digoxin once the adjunctive therapy to treat symptoms into the cutting-edge HF and reduce HF exacerbations from inside the patients who are not able to work properly to help you standard HF medication. 46 Due to age-related reductions in kidney setting and you may lean body mass, earlier patients, especially people, tend to want a lower life expectancy dose out-of digoxin to reach a great healing serum amount (web browser, 0.5–0.9 ng/mL).
