heart failure test results waiting tips

Overview

Heart failure is a long-term condition in which the heart is not pumping blood as well as it should. It does not mean the heart has stopped or is about to stop. When you are having tests for heart failure, it is normal to feel anxious while waiting for results. This article explains what heart failure is, what tests you may have, and how to look after yourself during the waiting period.

Heart failure is very common. Around 26 million people worldwide live with heart failure, and the number is rising as people live longer and survive heart attacks.

Heart failure is most often seen in older adults, especially those over 65. But it can also affect younger people who have had a heart attack, a viral infection of the heart, or a heart condition present from birth.

Symptoms

Common symptoms

• Shortness of breath, especially when lying down or during mild activity
• Feeling tired or weak most of the time
• Swelling in the ankles, legs, or abdomen due to fluid build-up
• Rapid weight gain over a few days (more than 2 to 3 kilograms in a week)
• A persistent cough or wheezing
• Needing to urinate more often at night

Symptoms in children

• Poor feeding or difficulty sucking
• Unusual tiredness or drowsiness
• Rapid breathing or breathlessness during feeding
• Sweating more than usual during feeds
• Swelling around the eyes or in the legs

Symptoms in older adults

• Confusion or memory problems, sometimes mistaken for dementia
• Feeling faint or dizzy, especially when standing up
• Falls or unsteadiness
• Reduced urine output despite drinking normally
• Loss of appetite or nausea

Causes

Main causes

• Coronary artery disease – narrowed or blocked arteries that reduce blood flow to the heart
• A previous heart attack that damaged part of the heart muscle
• High blood pressure that makes the heart work too hard for years
• Cardiomyopathy – a disease of the heart muscle itself, sometimes inherited
• Heart valve problems that disrupt normal blood flow
• Severe lung disease or chronic kidney disease

Risk factors

• Diabetes
• Smoking
• Obesity
• A family history of heart failure or sudden cardiac death
• Heavy alcohol use or recreational drug use
• Sleep apnoea (stopping breathing briefly during sleep)

When to see a doctor

See a doctor urgently if:

• If you develop sudden, severe breathlessness or chest pain, call your local emergency number right away.
• If you have a known heart problem and your symptoms get worse over a few hours, seek urgent medical care.
• If you faint or have a seizure-like episode, get emergency help.

Book a routine appointment if:

• If you have persistent tiredness, breathlessness, or swelling that does not go away, book an appointment with your doctor.
• If you are already waiting for test results and your symptoms are stable, continue your usual follow-up plan.
• If you are worried about new symptoms that are not severe, contact your healthcare team for advice.

Diagnosis

To diagnose heart failure, your doctor will ask about your symptoms, medical history, and family history. They will perform a physical examination and may listen to your lungs and heart. Several tests are then used to confirm whether heart failure is present, how severe it is, and what might be causing it.

Tests that may be done

• Blood tests – including a test called BNP or NT-proBNP, which measures a hormone released when the heart is stretched
• An electrocardiogram (ECG) – records the electrical activity of your heart
• An echocardiogram – an ultrasound scan that shows how well your heart pumps and if its chambers or valves are working properly
• A chest X-ray – looks for fluid in the lungs or an enlarged heart
• An exercise stress test – checks how your heart responds to physical activity
• A cardiac MRI – detailed scan of heart structure and function

What to expect at your appointment

Most of these tests are painless and do not require special preparation. You may need to remove your top clothing for an ECG or echocardiogram. You may be asked to fast for a blood test or before a stress test. Each test usually takes between 15 minutes and an hour. Results may take a few days to a few weeks. Your healthcare team will explain what each result means and will discuss next steps with you.

Treatment

Treatment for heart failure focuses on relieving symptoms, slowing the disease, and improving quality of life. It is not a cure, but many people live a long and active life with heart failure thanks to modern care and self-management.

Self-care at home

• Take all medicines exactly as prescribed, even if you feel well
• Weigh yourself every morning and tell your team if you gain more than 1–2 kilograms quickly
• Limit salt and avoid salty foods to reduce fluid build-up
• Stay as active as your doctor advises – gentle walking can help
• Stop smoking and limit alcohol
• Monitor your symptoms daily and write them down

Medical treatments

Medicines are the main treatment for heart failure. Doctors commonly prescribe a combination of medicines that help the heart pump better, remove extra fluid, relax blood vessels, and lower the workload on the heart. Many newer medicines are now available. Your doctor will decide which options are safest for you, based on your test results, other health conditions, and your needs. Always ask questions about any medicine you are taking.

When is surgery considered?

Some people with heart failure may need a procedure or surgery, such as fitting a pacemaker or an implantable defibrillator, repairing or replacing a heart valve, or, in severe cases, a heart transplant. These options are discussed only when medicines are not enough and your specialist team believes they will help.

Living with this condition

Living with heart failure means learning to manage your energy. Plan your day, rest before activities, and ask for help when you need it. Keep a diary of your daily weight and symptoms. Regular check-ups are important – do not skip them. It is also very common to feel worried or low after a heart failure diagnosis or while waiting for test results; you are not alone.

Lifestyle tips

• Stay physically active: walking, light cycling, or chair-based exercises are usually encouraged
• Weigh yourself daily after waking up, before drinking, and while wearing similar clothing
• Aim for 7–8 hours of sleep, and raise your head with an extra pillow if breathless at night
• Avoid heavy lifting and sudden strenuous activity
• Manage stress with breathing exercises, relaxation, or talking to someone you trust

Diet and exercise

Eat a heart-healthy diet with plenty of vegetables, fruit, whole grains, and lean protein. Limit added salt to less than 6 grams a day, and avoid adding salt at the table. A dietitian can help you adjust portion sizes and meals. Exercise should be regular but gentle – start slowly and only increase activity with your doctor's advice. Cardiac rehabilitation programs provide safe, supervised exercise and education.

Mental health and emotional wellbeing

Dealing with a heart failure diagnosis and the waiting period for results can cause anxiety, depression, or sleep problems. These are real and treatable. Talk to your doctor or nurse about how you are feeling. They can support you with counselling, group support, or other treatments that do not interfere with your heart care. If you are in distress, reach out to a crisis helpline in your country.

Prevention

Heart failure cannot always be prevented, but many cases are linked to conditions you can control. Keep blood pressure and cholesterol in a healthy range, manage diabetes, quit smoking, maintain a healthy weight, limit alcohol, and stay active. If you already have heart disease, following your treatment plan lowers your risk of heart failure.

Vaccines

Yes, vaccinations are important. Flu and pneumonia can make heart failure worse, so having an annual flu vaccine and a pneumonia vaccine may be recommended. Ask your healthcare team or local pharmacist about which vaccines are suitable for you.

Screening programmes

Screening for heart failure is not routine for everyone. However, if you have high blood pressure, diabetes, or a family history of heart disease, your doctor may check your heart with an ECG or echocardiogram as part of regular monitoring. Early detection of heart problems can help prevent heart failure.

Complications

If left untreated

• Fluid build-up in the lungs causing severe breathlessness
• Kidney damage from reduced blood flow
• An irregular heartbeat, which can be dangerous
• Hospital stays for worsening symptoms
• A reduced ability to walk short distances or do daily tasks

Long-term outlook

Heart failure is a serious condition, but the outlook is not as bleak as many people fear. With modern treatment, self-care, and regular follow-up, many people live for years with good quality of life. Symptoms can improve significantly once the right treatment plan is in place. Even if your test results take time, remember that every step of the journey is about finding the best way to help you feel better and live well.
