A heart failure specialist is a cardiologist with extra training in advanced heart failure and transplant cardiology. Consider seeing one if you have a low ejection fraction, repeated hospital stays, symptoms despite medicines, trouble tolerating medicines, or questions about devices, LVADs or transplant. Earlier referral gives more treatment options.

What is a heart failure specialist?
All cardiologists treat heart failure. A heart failure specialist has completed additional fellowship training in advanced heart failure and transplant cardiology after general cardiology training. That extra training focuses on fine-tuning complex medicine regimens, managing heart failure with other conditions such as kidney disease, evaluating unusual causes of cardiomyopathy, and deciding when patients may need advanced therapies such as mechanical heart pumps or transplant. Board certification in this subspecialty is available, and you can ask any physician about their training and certifications.
When to see a heart failure specialist
- Your ejection fraction is low (especially 35 percent or less) or falling.
- You have been hospitalized for heart failure, particularly more than once in a year.
- You still have breathlessness, fatigue or swelling despite medicines.
- Low blood pressure, kidney problems or high potassium prevent you from taking full doses of heart failure medicines.
- You need increasing doses of diuretics.
- You were diagnosed with cardiomyopathy and the cause is unclear, or there is a family history.
- You are considering an ICD, CRT, LVAD or heart transplant evaluation.
- You want a second opinion about your treatment plan; see our cardiology second opinion page.
Signs heart failure may be advancing
Specialists often use a simple set of warning signs that suggest it is time for more advanced care:
| Warning sign | Why it matters |
|---|---|
| Two or more heart failure hospitalizations in a year | Suggests current treatment is not keeping fluid and symptoms under control |
| Needing IV medicines to support the heart | Signals the heart may not maintain circulation on its own |
| Low blood pressure limiting medicines | Means fewer tools are available at standard doses |
| Worsening kidney function | Heart and kidneys affect each other in advanced disease |
| Rising diuretic needs | Fluid is becoming harder to control |
| Breathlessness with minimal activity or at rest | NYHA class III to IV symptoms |
| Repeated ICD shocks or rhythm problems | May need medication changes or ablation |
- Severe breathlessness or breathlessness at rest
- Chest pain or pressure
- Fainting or a shock from your ICD with symptoms
- Pink, frothy mucus or confusion
What happens at a heart failure specialist visit
Expect a thorough review of your history, medicines, hospital records and test results; an exam focused on fluid status; lab work; and often an updated echocardiogram and EKG. Your specialist will check whether you are on all appropriate guideline-directed medicines at the best tolerated doses, look for treatable causes, and discuss devices or advanced therapies when relevant. Bring your daily weight log and a list of all medicines.
Working with your heart failure team
Heart failure care works best as a team: your heart failure cardiologist, primary care doctor, nurses, pharmacist, dietitian and, often, cardiac rehabilitation staff. Hospital-based procedures such as advanced heart pumps are performed at affiliated hospitals, while ongoing medicine adjustments and monitoring happen in the office.
