Heart failure: what good care looks like
Heart failure means the heart is not pumping or filling as well as it should. Four proven medicine groups, started early and increased to target doses, lower the risk of dying and of hospital stays. Here is what the guidelines say and how to tell if you are getting that care.
The types of heart failure, explained simply
- HFrEF (reduced ejection fraction): the heart squeezes weakly.
- HFmrEF (mildly reduced): squeeze is a little low.
- HFpEF (preserved): the heart squeezes fine but is stiff and does not fill well.
Ejection fraction (EF) is the share of blood the left ventricle pumps out with each beat. A normal EF is about 55 to 70 percent. It is measured with an echocardiogram (a heart ultrasound), and sometimes with a cardiac MRI or a nuclear scan. HFrEF means an EF of 40 percent or less, HFmrEF 41 to 49 percent, and HFpEF 50 percent or more with signs that the heart is stiff.
Your EF can change. Many people with HFrEF improve on the four medicines below, which is one reason the medicines matter so much and why your EF should be rechecked after treatment is optimized.
HFrEF: the four pillars of guideline-directed medical therapy
The guidelines recommend four medicine groups together, started early and increased to target doses:
- ARNI (sacubitril/valsartan), or an ACE inhibitor or ARB if ARNI is not possible
- Evidence-based beta blocker: carvedilol, metoprolol succinate, or bisoprolol
- Mineralocorticoid receptor antagonist: spironolactone or eplerenone
- SGLT2 inhibitor: dapagliflozin or empagliflozin
Why all four
Why started early and increased
Additional therapies for selected patients
- Hydralazine plus isosorbide dinitrate: for Black patients with HFrEF who still have symptoms on the four pillars, and for anyone who cannot take an ARNI, ACE inhibitor, or ARB.
- Ivabradine: when the resting heart rate stays above 70 in normal rhythm despite the highest tolerated beta blocker dose.
- Vericiguat: for people recently hospitalized or needing IV diuretics whose heart failure is getting worse despite the pillars.
- Digoxin: an older medicine that can reduce hospital stays when symptoms persist; it does not lower death rates.
- Diuretics: water pills to relieve swelling and shortness of breath; the dose is adjusted to your weight and symptoms.
- IV iron: for iron deficiency (common in heart failure), it improves symptoms and exercise ability and reduces hospital stays.
- ICD and CRT devices: a defibrillator prevents sudden death when EF stays 35 percent or less on good treatment; resynchronization pacing helps selected people with a wide QRS on the ECG.
- Cardiac rehabilitation: supervised exercise improves how far you can walk, quality of life, and hospital stays.
HFpEF and HFmrEF
- SGLT2 inhibitors
- Nonsteroidal and steroidal mineralocorticoid receptor antagonists
- ARNI in selected patients
- GLP-1 receptor agonists for the obesity phenotype
- Blood pressure and atrial fibrillation management
What the evidence shows: in the EMPEROR-Preserved and DELIVER trials, SGLT2 inhibitors cut hospital stays for heart failure by about one fifth in people with preserved or mildly reduced EF, which is why the guideline recommends them. Spironolactone and the newer finerenone reduce hospital stays in selected patients. Sacubitril/valsartan helps most in the mildly reduced and low-normal range. In people with obesity and HFpEF, semaglutide improved symptoms and walking distance in the STEP-HFpEF trials. Controlling blood pressure and treating atrial fibrillation matter because both drive HFpEF.
What guideline-based care looks like at a visit
At every visit a good clinician checks your weight and symptoms (breathing, swelling, how far you can walk), your blood pressure and heart rate, and reviews every medicine against the four pillars. Labs are checked after dose changes: kidney function, potassium, and often BNP or NT-proBNP. If you are not at target doses, there should be a plan to get there over the next weeks, not months. The visit should also cover whether you need a device evaluation (ICD or CRT), a cardiac rehab referral, vaccines (flu, COVID-19, pneumococcal, RSV), sleep apnea, iron levels, and salt and fluid guidance. You should leave knowing which symptoms mean call today.
Red flags that a clinician is not following the guidelines
- You have HFrEF and are on fewer than the four pillars with no explanation
- Doses have not been increased in months without a reason
- Supplements, peptides, or compounded drugs are sold as treatment
- Proven medicines are stopped because “you feel fine”
- No plan for a device evaluation when your ejection fraction stays low
Why it matters
Most eligible patients are not on all four pillars, and each pillar independently lowers death and hospitalization. Put together, the four pillars can add years of life: an analysis of the landmark trials estimated that a 55-year-old with HFrEF who takes all four gains about 6 extra years free of death or hospitalization compared with older two-drug treatment. Each medicine class on its own lowers the risk of dying by roughly 15 to 30 percent in trials. Yet registry studies show fewer than 1 in 5 eligible patients is on all four, and many are on doses far below target. Choosing a clinician who follows the guideline is the single biggest thing you control.
Questions to ask your doctor
- Which type of heart failure do I have, and what is my ejection fraction?
- Which of the four pillars am I on? If not all four, why?
- Are my doses at target? What is the plan to get there?
- Do I need a device evaluation or cardiac rehab?
- What symptoms should make me call you today?

Common questions
What is GDMT?
Guideline-directed medical therapy: the set of medicines the guidelines recommend for heart failure with reduced ejection fraction, given together and increased to target doses.
Do I need all four medicines?
For HFrEF the guidelines recommend all four pillars unless there is a specific medical reason not to use one. Each one lowers the risk of dying and of hospital stays on its own, and the benefits add up.
Can heart failure get better?
Yes. With guideline-based treatment many people feel better, stay out of the hospital, and see their ejection fraction improve.

2022 AHA/ACC/HFSA Guideline for the Management of Heart Failure
- For heart failure with reduced pumping (HFrEF), four medicine classes are recommended together: an ARNI (or ACE inhibitor or ARB), a beta blocker, an MRA, and an SGLT2 inhibitor.
- Each of the four lowers death and hospital stays on its own; together the benefit is large.
- SGLT2 inhibitors are also recommended for heart failure with preserved pumping (HFpEF), which had few options before.
- Devices (ICD, CRT), cardiac rehab, and treating iron deficiency are covered for the right patients.
