The 20 Best Heart Failure Doctors near Portsmouth, NH

Heart failure is a condition in which the heart is no longer able to pump oxygen-rich blood to the rest of the body efficiently. This causes symptoms to occur throughout the body.

Heart failure, also called congestive heart failure, is managed by a team of specialized doctors: 

• Primary care doctors are often the first to identify signs of heart failure. They help monitor symptoms, manage overall health, and coordinate care among specialists. They play an important role in early detection and ongoing support. 

• Cardiologists, including heart failure specialists, lead treatment by diagnosing the condition, prescribing medications, and recommending lifestyle changes. In advanced cases, they may oversee procedures like implantable devices and heart transplants. 

• Pulmonologists manage lung-related symptoms, such as shortness of breath, due to fluid buildup. They may prescribe diuretics or oxygen therapy to relieve congestion and improve breathing. 

• Electrophysiologists treat heart rhythm issues (arrhythmias) that may develop with heart failure. They stabilize rhythms through medications, procedures, or implanted devices like pacemakers or defibrillators. 

Symptoms of heart failure can vary by type and level of intensity from person to person. 

Common signs include: 

• Shortness of breath, especially during activity or while lying down 

• Fatigue and weakness 

• Swelling in the legs, ankles, and feet 

• Rapid or irregular heartbeat 

• Persistent cough or wheezing, often with white or pink mucus 

• Difficulty concentrating and a general feeling of being weak or tired 

Heart failure is diagnosed through a combination of medical history, physical exams, and tests that assess heart function.  

• Electrocardiogram (ECG or EKG): Small sensors attached to the skin detect the heart’s rhythm and identify any irregularities, which can signal heart stress or damage. 

• Echocardiogram: This ultrasound test uses sound waves to create live images that show the heart’s size, shape, and how well it pumps, helping doctors assess damage or weak heart muscle.  

• Blood Tests: Tests like the B-type natriuretic peptide (BNP) measure specific markers that show heart strain. Elevated BNP levels suggest the heart is under stress or working harder than normal. 

• Chest X-ray: This imaging test shows the size of the heart and any fluid buildup in the lungs. Enlarged heart size or lung congestion can suggest heart failure.  

• Stress Test: This test checks heart performance under exertion, usually involving exercise or medications that stimulate the heart. Doctors look at heart rate, blood pressure, and rhythm to identify defects. 

• Cardiac MRI: A cardiac MRI (magnetic resonance imaging) uses magnetic fields and radio waves to create detailed images of the heart, which allows doctors to spot any structural and functional issues. 

Heart failure progresses in four stages, from A to D. 

• Stage A: High risk of developing heart failure, but without symptoms or structural heart disease. 

• Stage B: Structural heart disease is present but without symptoms of heart failure. 

• Stage C: Symptoms like fatigue and shortness of breath appear along with structural heart issues. 

• Stage D: Advanced heart failure, where symptoms continue even with treatment. 

By further classifying patients in stage C and stage D heart failure, healthcare teams can better understand how to treat symptoms in more advanced stages. The most common approach is to categorize patients based on symptom severity during physical activity.  

• Class I means there is no limitation of physical activity 

•  Class II means there is a slight limitation of physical activity 

• Class III: means symptoms cause discomfort and limitation of physical activity 

• Class IV means symptoms are present even at rest and any activity causes discomfort 

Both heart failure doctors and cardiologists treat heart failure, but they bring different levels of specialization. A cardiologist is a doctor who treats diseases of the heart and blood vessels, while a heart failure doctor is a cardiologist who specializes in heart failure. Cardiologists are experts in diagnosing and managing a wide range of heart conditions. Heart failure doctors focus specifically on heart failure and may prescribe advanced treatments or therapies. While both types of doctors are essential in treating heart failure, heart failure specialists provide a more focused approach for individuals with complex or severe cases.  

Estimating survival rate is complicated because the life expectancy of someone with heart failure depends on what stage the condition is, how well they respond to treatment, and lifestyle factors. Early stages of heart failure, especially with lifestyle changes and treatment, can slow down progression. In later stages, treatment focuses on symptom management and improving quality of life. Regular follow-ups with a heart failure expert can help patients live longer, healthier lives. However, if heart failure is left untreated, it will be fatal.  

There are various reasons why you may want to see a specialist, such as: 

• Your primary care provider recommends it. 

• Your condition requires expert knowledge and specialized care. 

• Your symptoms persist or worsen despite treatment. 

• You need specialized testing or procedures. 

• You want a second opinion.  

It’s important to see a provider with expertise in your specific condition. Each provider profile in MediFind’s doctor database includes information on which conditions they treat, years of experience, research contributions, languages spoken, insurance plans accepted, and more.

MediFind’s rankings are based on a variety of data sources, such as the number of articles a doctor has published in medical journals, participation in clinical trials and industry conferences, as well as the number of patients that provider sees for a given condition. Note that MediFind’s provider database is not based on user reviews, and providers do not pay to be included in the database. 

Most profiles in MediFind’s doctor database include a list of insurance plans accepted by that provider. However, it’s a good idea to contact the provider’s office to make sure they still accept your insurance, then doublecheck by contacting your insurance plan to confirm they’re in network. 

MediFind offers direct scheduling for certain providers using the “Request Appointment” button on that provider’s profile. If the schedule option is not available for a provider, tap the red “Show Phone Number” button on their profile to get their contact information. If you prefer to find providers who offer online scheduling, select “Schedules online” under the “Availability” category of the filter feature on the left side of the Heart Failure doctor search results page. 

Second opinions are an opportunity to confirm a diagnosis and its root cause, learn about alternative treatment options, or simply gain peace of mind. Many people, especially those with serious diagnoses, get second opinions so they can understand all their options and make informed decisions, so don’t hesitate to get one if you have any doubts or need more information or clarification regarding your care. Note that some insurance plans require second opinions, while others don’t cover second opinions, so be sure to confirm with your insurance provider first.   

Prepare for your appointment by gathering the following items: 

• Copies of medical records (dating back at least one year) 

• Your medical history, including illnesses, medical conditions, surgeries, and other doctors you see 

• Family history of disease 

• List of current prescription drugs, over-the-counter medicines, vitamins, and herbal remedies or supplements including names and doses 

• Allergies to medications, food, latex, insects, etc.  

• List of questions and concerns 

• Your insurance card 

You might also contact the provider’s office to see if they offer transportation or childcare services or if you’re allowed to bring a loved one for support or to take notes during your visit. 

Here are some sample questions: 

• Can you explain in simple terms what this condition is and how it’s treated? 

• What symptoms or side effects should I watch for? 

• What tests will be involved, and when can I expect results? 

• Are there other specialists I need to see? 

• What’s the best way to reach you if I have follow-up questions? 

MediFind’s Clinical Trials tool asks you a series of questions to help you narrow down your search by health condition, age, gender, location, how far you’re willing to travel, and more. Each question you answer filters down the number of trials until you find the ones that are most relevant to you.
