Case 1: A 68-year-old female patient presents with fatigue, chest pain, palpitations, dyspnea, and syncope while performing normal physical activity. She is comfortable at rest, with limited impairment of functional status. She is categorized as having HFpEF NYHA Class II, with an LVEF of 58% and an eGFR of 61 mL/min/1.73 m2. She is currently taking ACE inhibitors and diuretics.
Case 2: A 65-year-old man is experiencing symptoms fatigue, chest pain, palpitations, dyspnea, and syncope with less than normal physical activity. He is comfortable at rest only, with limitations on functional status. He recently transitioned to HFpEF NYHA Class III, with an LVEF of 35% and eGFR of 58 mL/min/1.73 m2. He is currently taking an ARB, diuretic, and beta blocker.
In both patients, the addition of which agent would result in a relative risk reduction in time to cardiovascular death or hospitalization due to heart failure? Before prescribing this drug, in which patients should renal function and volume status be tested? What are the most common adverse reactions for this drug (i.e., occurring in ≥5% of patients)?
In patient 2, I would change ARB to Entresto and add spironolactone. I would tritrate up the dose of Entresto in follow up appotments as BP allows. I might add empagliflozin in the future if insurance coverage allows. Recheck LV function on future echo, and consider CRM therapy if LVEF< still.
For the second patient would also add an SGLT2 inhibitor, preferably Farxiga with additional renal data. I would also change ARB to Entresto with worsening LVEF and strongly consider addition of Spironolactone. Would carefully monitor potassium and renal function in this patient with additional medications. Following three months of GDMT with the above changes, if the LVEF is not improved would recommend placement of an ICD device.
For the 1st patient who had HFpEF, I’d add SGLT2. In addition, Aldactone could have some benefit.
For the 2nd patient, I’d also add SGLT 2, switch to Entresto, and add Aldactone. All Med changes to be done in stepwise fashion.
I usually get labs every 2 weeks while making changes. (Chem7 and BNP). Use of SGLTs is associated with increased risk of UTIs.
For the second patient I would change the ARB to Entresto hold the diuretic and add Farxiga. Again would repeat GFR assessment in one month and follow closely. IF renal function remains stable would add Spironolactone or Inspra.
in case 2 would switch to entresto, stop stand alone arb and would add farxiga
In patient 2, I would start by changing ARB to Entresto and adding spironolactone. Titreate up Entresto as BP allows. Due to naturetic effect of neprilisin inhibitor, consider reduction in diuretic dose. . Also, recheck lytes and renal function in 1-2 weeks. Add empagliflozin nextaiming for standard four drug therapy for HFrEF (beta blocker, ARNI, MRA, and SGLT2 inhibitor). Recheck LV function on future echo, and consider CRM therapy if LVEF< still.
Need to make sure patient not volume depleted or has severe Ckd before using ARNI or MRA.
Need to discuss risk of GU infections with SGLT2s.
For case 2, spironolactone first, with change ARB to Entresto; add Farxiga or Jardiance.
Jardiance, spironolactone, and Entresto are all impacted by renal fx and potassium level, and needs to be known before starting the medication.
Volume status needs to be known to avoid hypovolemia and hypotension.
Discuss risk of GU infections with Jard/Farx
Barrier to care as always is pre/auth, formulary status, and cost.
Case 2: add SGLT2i for above benefits. In addition I would consider changing from ARB to Entresto and add spironolactone.
I monitor lytes/cr in a week after starting and often lower the dose of current diuretics to avoid hypovolemia.
Patients should be made aware of increased risk of GU infections.
Case 2: Would consider change to Entresto and add SGLT2 inhibitor
Cost may be a barrier
Fluid status should be managed in both patients
Risk for UTI/infection with SGLT2i
Case 2: Change to Entresto and add SGLT2 inhibitor
Both may be limited by affordability.
I am more cautious in patients whose glycemic control is very poor as my sense is that this may increase the risk of Fournier's etc. I typically emphasize the data that suggest the SGLPT2 drugs may help with weight loss if people are reluctant.
Notably, for Case 2 would favor the replacement of the ARB for an ARNI.
