Understanding echo results patient guide

Overview

An echocardiogram (echo) is a safe, painless ultrasound scan that creates moving pictures of your heart. It shows how well your heart is pumping, how the valves are working, and if there is any fluid around the heart. The results help your doctor understand what is happening with your heart and decide on the best care plan.

Yes, echocardiograms are one of the most common heart tests performed worldwide.

Anyone who has symptoms such as chest pain, shortness of breath, palpitations, or swelling in the legs may have an echo. It is also used to monitor people with known heart conditions.

Symptoms

Common symptoms

• Shortness of breath (especially with activity or when lying flat)
• Chest pain or discomfort
• Palpitations (feeling like your heart is racing, fluttering, or skipping a beat)
• Swelling in the ankles, feet, or legs
• Unexplained fatigue or tiredness

Symptoms in children

• Poor feeding or difficulty feeding
• Rapid breathing or breathing hard
• Blue tint to the lips or skin (cyanosis)
• Failure to gain weight or grow as expected

Symptoms in older adults

• Shortness of breath while doing everyday activities
• Dizziness or feeling light-headed
• Fainting episodes (syncope)
• Confusion or sudden tiredness

Causes

Main causes

• Problems with the heart valves (e.g., leaking or narrowing)
• Weakness of the heart muscle (cardiomyopathy)
• Weakening of the heart's pumping ability (heart failure)
• Fluid buildup around the heart (pericardial effusion)
• Congenital heart defects (heart problems present from birth)

Risk factors

• High blood pressure
• Coronary artery disease
• Heart attack in the past
• Family history of heart disease
• Diabetes
• Older age
• Obesity

When to see a doctor

See a doctor urgently if:

• If you have any of the emergency symptoms listed above, call your local emergency number immediately.
• If you have new or worsening breathlessness, chest discomfort, or leg swelling, seek same-day medical advice.

Book a routine appointment if:

• If you have a known heart condition, follow your doctor’s recommended schedule for follow-up echos.
• If you have risk factors for heart disease and develop new symptoms, make an appointment with your GP or cardiologist.

Diagnosis

An echocardiogram is the main test used to see the structure and function of the heart. The results are reviewed by a cardiologist, who will discuss any abnormal findings with you and your doctor.

Tests that may be done

• Transthoracic echocardiogram (standard echo through the chest wall)
• Transesophageal echocardiogram (probe passed down the throat for clearer images – usually done under sedation)
• Stress echo (echo done before and after exercise or medication to see how the heart responds to stress)
• Doppler echo (to measure blood flow across heart valves)

What to expect at your appointment

You will lie on a bed. A gel is applied to your chest, and a small wand (transducer) is moved over your chest to capture images. There is no pain, but you may feel mild pressure. The scan takes about 30 minutes. You can go back to normal activities right after.

Treatment

Treatment depends on what the echo shows. The goal is to improve heart function, relieve symptoms, and prevent complications. Your doctor will create a personal plan that may include lifestyle changes, medications, procedures, or surgery.

Self-care at home

• Eat a heart-healthy diet low in salt, saturated fat, and added sugars.
• Stay physically active as advised by your doctor – often 30 minutes of moderate exercise most days.
• Avoid smoking and limit alcohol.
• Monitor your weight and check for swelling in your legs or ankles.
• Keep a record of your symptoms and bring it to appointments.

Medical treatments

Medications may be prescribed to control blood pressure, reduce fluid buildup, improve heart pumping, or manage heart rhythm problems. Always take medicines exactly as prescribed and never stop without talking to your doctor.

When is surgery considered?

If the echo shows severe valve disease, a large hole in the heart, or other structural problems, surgery or a catheter-based procedure may be needed. Your cardiologist will explain the options and refer you to a heart surgeon if appropriate.

Living with this condition

Stay in close contact with your healthcare team. Attend all follow-up appointments and keep a list of your medicines. Let your doctor know if your symptoms change.

Lifestyle tips

• Maintain a healthy weight.
• Control blood pressure and cholesterol through diet and medicine if needed.
• Find healthy ways to manage stress, such as relaxation exercises or talking to a counsellor.
• Get enough sleep and rest when you feel tired.

Diet and exercise

A heart-healthy diet includes plenty of vegetables, fruits, whole grains, lean protein, and healthy fats. Limit processed foods and salt. Exercise such as walking, swimming, or cycling at a moderate pace can help your heart stay strong – always follow your doctor's advice on safe activity levels.

Mental health and emotional wellbeing

Living with a heart condition can cause worry, anxiety, or low mood. These feelings are normal. Talk to your healthcare team – they can connect you with a counsellor or a cardiac support group. You don't have to cope alone.

Prevention

Not all heart problems can be prevented, but you can lower your risk by keeping blood pressure, cholesterol, and blood sugar in a healthy range. A healthy lifestyle and regular check-ups help catch problems early.

Vaccines

Getting recommended vaccines – such as the flu shot and pneumonia vaccine – is important for people with heart conditions. Ask your healthcare provider which vaccines are right for you.

Screening programmes

If you have a family history of heart disease or other risk factors, talk to your doctor about whether you should have an echo or other heart tests even without symptoms.

Complications

If left untreated

• Worsening heart failure, leading to more severe shortness of breath and swelling
• Irregular heart rhythms (arrhythmias) that can increase risk of stroke
• Valve problems that can cause permanent damage to the heart muscle
• Fluid buildup in the lungs (pulmonary edema) – a medical emergency

Long-term outlook

With the right treatment and lifestyle changes, most people with heart conditions found on an echo can lead active, fulfilling lives. Early detection and good management make a big difference. Your healthcare team is there to support you every step of the way.
