GDMT for HFpEF
Start an SGLT2 inhibitor (dapagliflozin 10 mg or empagliflozin 10 mg daily) immediately upon diagnosis—this is the only proven disease-modifying therapy that reduces heart failure hospitalizations and cardiovascular death in HFpEF. 1, 2
First-Line Disease-Modifying Therapy
- SGLT2 inhibitors are the cornerstone of HFpEF management with proven mortality and morbidity benefits that should be initiated without delay 1, 2
- Dapagliflozin reduced the composite endpoint of worsening heart failure and cardiovascular death by 18% (HR 0.82) and heart failure hospitalizations by 23% (HR 0.77) in the DELIVER trial 1
- Empagliflozin reduced heart failure hospitalization or cardiovascular death by 21% (HR 0.79) in EMPEROR-PRESERVED 1
- A critical pitfall is delaying SGLT2 inhibitor initiation—these should be started at the first visit after diagnosis 2
Symptom Management with Diuretics
- Use loop diuretics at the lowest effective dose to relieve congestion, targeting symptoms like orthopnea and paroxysmal nocturnal dyspnea 1, 2
- Titrate diuretic doses based on daily weights, edema, and congestion status 2
- Avoid excessive diuresis which leads to hypotension, renal dysfunction, and impaired tolerance of other medications 2
- Consider increasing the loop diuretic dose before adding combination diuretic therapy if initial response is inadequate 2
- Thiazides can be added as adjunctive therapy in hypertensive patients or those with refractory edema despite loop diuretics 3
Additional Pharmacological Considerations
- Mineralocorticoid receptor antagonists (spironolactone) should be considered particularly in patients with LVEF in the lower range of preservation (40-50%) 2
- ARNIs (sacubitril/valsartan) may benefit selected patients, especially women and those with LVEF below the upper range 2
- Monitor renal function and electrolytes regularly when using MRAs 4
Comorbidity Management
Hypertension
Diabetes
- Prioritize SGLT2 inhibitors for glycemic control given their dual benefits for both diabetes and heart failure 1, 2
Atrial Fibrillation
- Control ventricular rate using beta-blockers or non-dihydropyridine calcium channel blockers 2
- Prescribe anticoagulation based on CHA₂DS₂-VASc score 4
- Use cardioselective beta-blockers cautiously in patients with concurrent COPD 4
Non-Pharmacological Interventions
- Refer to supervised exercise training programs (Class 1 recommendation)—these provide substantial, clinically relevant improvements in aerobic exercise capacity and quality of life comparable to or greater than pharmacological interventions 3, 1, 2
- Exercise therapy is safe in chronic, stable HFpEF and should be pursued aggressively for referral and adherence 3
- Prescribe sodium restriction to <2-3 g/day to reduce congestive symptoms 3, 1, 2
- Recommend weight reduction in obese patients as obesity is a key modifiable target in the cardiometabolic HFpEF phenotype 1, 5
Monitoring Strategy
- Monitor symptoms, vital signs, daily weights, renal function, and electrolytes regularly 1, 2
- Adjust diuretic doses based on congestion status to prevent both under- and over-diuresis 1, 2
- Consider wireless pulmonary artery pressure monitoring in selected patients with recurrent hospitalizations 2
Key Pitfalls to Avoid
- Do not delay SGLT2 inhibitor initiation—this is the only therapy with proven mortality benefits and should be started immediately 2
- Avoid excessive diuresis leading to hypotension, azotemia, and medication intolerance 2
- Do not assume all heart failure medications work in HFpEF—unlike HFrEF, most traditional heart failure therapies have not shown efficacy in HFpEF 3
- Rule out HFpEF mimics (cardiac amyloidosis, hypertrophic cardiomyopathy, pericardial disease) that require specific treatments 2
