Core agents and when to use them; integrate BP, renal function, and phenotype.
SGLT2 inhibitors (first-line)
Start in most HFpEF patients; improves HF outcomes regardless of diabetes status; generally well tolerated [1], [2].
Monitor for volume depletion; hold during acute illness or peri-procedure.
Additive to ARNI, MRA, and diuretics.
ARNI (sacubitril/valsartan)
Consider for symptomatic HFpEF, especially with higher natriuretic peptides or hypertensive phenotype and adequate BP [1], [2].
Benefits include symptom relief and potential reduction in HF events; watch for hypotension and renal effects.
Washout if switching from ACE inhibitor.
MRA (spironolactone/eplerenone)
Useful for persistent congestion and selected patients to reduce HF hospitalization risk; monitor K+ and eGFR closely [1], [2].
Avoid if hyperkalemia or advanced CKD; consider low starting doses.
Diuretics
Loop diuretics are cornerstone for symptom relief; use thiazide synergy for resistance [4], [5].
Aim for euvolemia to avoid renal dysfunction.
Educate on weight-based self-adjustment where appropriate.
Blood pressure control
Target guideline-directed BP goals; ARNI/ACEi/ARB, diuretics, and CCBs commonly used [4].
Avoid excessive beta-blockade unless specific indications (AF/ischemia).
Diabetes/obesity therapies
SGLT2 inhibitors for HF benefit; GLP-1 RAs for weight loss and metabolic control in obese/diabetic HFpEF [5], [6].
Avoid agents that cause sodium/water retention.
