Heart Failure Symptoms, Diagnosis, and Treatment Options
Heart failure is a chronic condition where the heart is unable to pump blood effectively to meet the body’s needs. It can develop due to various underlying health issues, such as high blood pressure, coronary artery disease, or diabetes. Diagnosis and treatment are essential to manage symptoms, improve quality of life, and potentially extend lifespan.
How Heart Failure Is Diagnosed: Tests and Procedures Explained
Initial Evaluation
To determine whether someone has heart failure, a healthcare provider begins by conducting a physical examination and asking about any symptoms the person may be experiencing, such as fatigue, shortness of breath, or swelling in the legs. The provider also reviews the individual’s medical history and checks for risk factors like:
- Hypertension (high blood pressure)
- Coronary artery disease
- Diabetes
Using a stethoscope, the provider listens for unusual heart sounds (such as murmurs) and evaluates lung sounds for signs of fluid accumulation. The neck veins are examined for swelling, and the legs and abdomen may be checked for signs of fluid retention.
Diagnostic Tests
A range of tests may be used to confirm heart failure and understand its severity:
- Blood Tests: Can reveal underlying conditions and measure levels of certain biomarkers (such as BNP or NT-proBNP) that are elevated in heart failure.
- Chest X-ray: Helps visualize the heart and lungs, showing any fluid buildup or changes in heart size.
- Electrocardiogram (ECG/EKG): Records the electrical activity of the heart and can detect abnormal rhythms or previous heart damage.
- Echocardiogram: An ultrasound test that shows detailed images of the heart’s structure, function, and movement of the heart valves.
- Ejection Fraction (EF): Measured during an echocardiogram, EF assesses how much blood the heart pumps out with each beat. An EF of 50% or higher is normal, but heart failure can still occur at this level.
- Stress Tests: Involves exercise or medication to assess how the heart performs under strain.
- Cardiac CT Scan: Provides cross-sectional images of the heart to identify abnormalities.
- Cardiac MRI: Offers detailed pictures of the heart using magnets and radio waves.
- Coronary Angiography: A catheter-based test where contrast dye is injected to visualize blocked or narrowed coronary arteries.
- Myocardial Biopsy: In rare cases, a small tissue sample is taken from the heart muscle to identify specific diseases affecting the heart.
Stages and Classifications of Heart Failure: NYHA and ACC/AHA Guidelines
Heart failure is classified to determine the severity and guide treatment strategies. Two primary systems are used:
1. New York Heart Association (NYHA) Functional Classification
- Class I: No symptoms during normal physical activity.
- Class II: Mild symptoms with ordinary activity, but comfortable at rest.
- Class III: Significant limitation in activity due to symptoms, even with less-than-normal exertion.
- Class IV: Symptoms are present even at rest; activity is severely limited.
2. ACC/AHA Stages of Heart Failure
- Stage A: High risk of heart failure, but no structural heart disease or symptoms.
- Stage B: Heart disease is present, but no signs or symptoms.
- Stage C: Structural heart disease with current or past symptoms.
- Stage D: Advanced disease requiring specialized interventions.
Healthcare professionals often use both systems to develop comprehensive treatment plans.
Effective Heart Failure Treatment Options and Strategies
Heart Failure Symptoms, Diagnosis, and Treatment Options

Treatment depends on the type, cause, and severity of heart failure. The main goals are to improve heart function, manage symptoms, and prevent further damage.

Lifestyle Changes for Managing Heart Failure Long-Term
- Reducing sodium intake
- Managing stress
- Exercising regularly as tolerated
- Limiting alcohol
- Quitting smoking
- Monitoring weight daily for signs of fluid buildup
2. Medications
A combination of medications is often used to manage symptoms and improve heart function:
ACE Inhibitors
These relax blood vessels and lower blood pressure, easing the heart’s workload.
- Examples: Enalapril, Lisinopril, Captopril
ARBs (Angiotensin II Receptor Blockers)
Alternative to ACE inhibitors for those who experience side effects.
Examples: Losartan, Valsartan, Candesartan

ARNIs (Angiotensin Receptor-Neprilysin Inhibitors)
A combination medication that reduces hospitalizations in patients with reduced ejection fraction.
- Example: Sacubitril-Valsartan (Entresto)
Beta Blockers
Slow the heart rate and lower blood pressure to reduce strain on the heart.
- Examples: Carvedilol, Metoprolol, Bisoprolol
Diuretics (Water Pills)
Help remove excess fluid, making it easier to breathe and reducing swelling.
- Example: Furosemide (Lasix)
Potassium-Sparing Diuretics (Aldosterone Antagonists)
Used in advanced heart failure but may increase potassium levels.
- Examples: Spironolactone, Eplerenone
SGLT2 Inhibitors
Originally used for diabetes, now shown to benefit heart failure patients regardless of diabetic status.
- Examples: Dapagliflozin (Farxiga), Empagliflozin (Jardiance)
Digoxin
Improves the heart’s pumping ability and controls heart rate in arrhythmias.
Hydralazine and Isosorbide Dinitrate
Combined therapy to dilate blood vessels, especially effective in certain populations.
Vericiguat
An oral medication that reduces hospital visits and deaths in high-risk patients.
Positive Inotropes
IV medications for hospitalized patients with severe heart failure to boost heart function temporarily.
Other medications like nitrates, statins, or blood thinners may be prescribed to manage associated conditions or symptoms.
Living with Heart Failure: Support, Care, and Quality of Life
In cases where heart failure symptoms suddenly worsen, hospitalization may be necessary. In the hospital, patients may receive:
- IV medications
- Oxygen therapy
- Adjustments in their medication regimen
In severe cases, long-term oxygen therapy may be needed at home.
Surgical and Device-Based Treatments
When medications are not enough, surgical options or devices may be considered:
Coronary Artery Bypass Graft (CABG)
Used when blocked arteries are reducing blood flow to the heart.
Heart Valve Repair or Replacement
Required if faulty heart valves contribute to heart failure.
Implantable Cardioverter-Defibrillator (ICD)
A device that monitors heart rhythms and delivers shocks if dangerous arrhythmias are detected.
Cardiac Resynchronization Therapy (CRT)
Coordinates the beating of the heart’s lower chambers using electrical impulses.
Ventricular Assist Device (VAD)
A mechanical pump that helps circulate blood. It’s often used in patients awaiting a heart transplant or those not eligible for one.
Heart Transplant
Recommended in severe, end-stage heart failure when other treatments fail. Not all patients are suitable candidates, and evaluation by a specialized team is necessary.
Palliative and End-of-Life Care
Palliative Care
Focuses on relief from symptoms and improving quality of life, regardless of the stage of disease. It can be combined with curative treatments.
Hospice Care
For individuals with advanced heart failure where life-prolonging treatments are no longer effective or desired. Hospice offers comfort-focused care, usually at home or in a specialized facility.
Advance Care Planning
It is important to discuss end-of-life wishes with family and the healthcare team. This includes decisions about resuscitation and whether to deactivate devices like ICDs.
Support and Resources
Emotional and psychological support is a vital part of managing heart failure. Many people benefit from:
- Counseling
- Support groups
- Education about the condition
Facilities like the Mayo Clinic offer specialized care, coordinated support, and access to clinical trials for those living with heart failure.
Conclusion
Heart failure is a complex condition, but with proper diagnosis, staging, and treatment—including medications, lifestyle changes, and sometimes surgical interventions—many people can manage the disease effectively and live longer, healthier lives. Collaborating with healthcare providers and staying informed about available options is key to improving outcomes.
