heart in older adults

Overview

Heart health in older adults refers to how well your heart works as you age. As we get older, the heart and blood vessels naturally change, which can increase the risk of conditions like high blood pressure, heart disease, or heart failure. Taking care of your heart becomes even more important with age.

Yes, heart conditions become more common as we age. Over half of adults over 60 have high blood pressure (a key heart risk factor), and conditions like heart failure and atrial fibrillation affect many older people.

Heart health concerns affect everyone as they get older, but risk is higher in people with a family history of heart disease, those who smoke, have diabetes, or who have an unhealthy diet and low physical activity.

Symptoms

Common symptoms

• Chest pain, pressure, or tightness (often called angina – a sign your heart isn't getting enough blood)
• Shortness of breath during everyday activities
• Swelling in your ankles, feet, or legs (fluid retention – may signal heart failure)
• Unexplained fatigue or feeling very tired
• Irregular or rapid heartbeat (palpitations)
• Dizziness or lightheadedness

Symptoms in children

• This topic does not apply to children – heart issues in children are different and need separate guidance.

Symptoms in older adults

• Shortness of breath when resting or doing light tasks
• Increased fatigue or weakness
• Swelling in the lower legs or ankles
• Confusion or trouble thinking (can result from reduced blood flow to the brain)
• Frequent coughing or wheezing (sometimes a sign of fluid in the lungs)
• Loss of appetite or feeling sick

Causes

Main causes

• Age-related changes in the heart and blood vessels, such as stiffening of arteries
• High blood pressure (hypertension) – puts extra strain on the heart
• Coronary heart disease – buildup of fatty deposits in the arteries
• Heart failure – the heart doesn't pump blood as well as it should
• Atrial fibrillation – a common type of irregular heartbeat in older adults

Risk factors

• Increasing age (especially over 65)
• Smoking or exposure to secondhand smoke
• High blood pressure
• High cholesterol
• Diabetes
• Being overweight or obese
• Lack of physical activity
• Unhealthy diet (high in salt, fat, and sugar)
• Family history of heart disease
• Stress and depression

When to see a doctor

See a doctor urgently if:

• Any chest pain or discomfort that is new or lasts more than a few minutes
• Sudden shortness of breath that doesn't go away
• Fainting or near-fainting
• Severe dizziness or confusion

Book a routine appointment if:

• Unexplained tiredness or swelling in your feet or ankles
• Heart palpitations that come and go
• A gradual change in how you feel during daily activities (less energy, more breathless)
• If you have risk factors like high blood pressure or diabetes and haven't had a check-up recently

Diagnosis

Your doctor will start by asking about your symptoms and medical history. They will listen to your heart and lungs and check your blood pressure, pulse, and breathing. Based on that, they may suggest tests to see how your heart is working.

Tests that may be done

• Blood tests (to check cholesterol, blood sugar, and other markers)
• Electrocardiogram (ECG or EKG – records the electrical activity of your heart)
• Echocardiogram (ultrasound of the heart – shows heart structure and pumping)
• Chest X-ray (to check heart size and fluid)
• Exercise stress test (walking on a treadmill while your heart is monitored)
• Holter monitor (a portable device that records your heart rhythm for 24–48 hours)

What to expect at your appointment

Most heart tests are painless and noninvasive. You might feel a bit cold from the gel used in an ultrasound, or slightly breathless during an exercise test. Your doctor will explain each step. Results usually come within days or weeks, and your GP or specialist will discuss them with you.

Treatment

Treatment for heart conditions in older adults depends on the specific problem. The goal is to control symptoms, prevent further damage, and improve quality of life. Options include lifestyle changes, medications (taken as prescribed by your doctor), and sometimes procedures or surgery.

Self-care at home

• Eat a heart-friendly diet with plenty of fruits, vegetables, whole grains, and lean proteins
• Limit salt, saturated fats, and added sugars
• Stay as physically active as you can – even gentle walking helps
• Quit smoking if you smoke
• Limit alcohol to recommended amounts
• Manage stress with relaxation techniques or hobbies
• Take all medications exactly as prescribed – never stop or change doses on your own

Medical treatments

Doctors may prescribe medicines to lower blood pressure, reduce cholesterol, control heart rhythm, thin the blood (to prevent clots), or help the heart pump better. Some people may need devices like a pacemaker or procedures such as angioplasty (opening blocked arteries) or heart valve repair. Surgery, like bypass grafting, is an option for severe cases. Always talk to your doctor about what's right for you.

When is surgery considered?

Surgery is considered when less invasive treatments don't control symptoms or when there's a serious blockage or valve problem. Examples include coronary artery bypass grafting (CABG) or valve replacement. Your doctor will discuss the risks and benefits based on your age and overall health.

Living with this condition

Living with a heart condition means paying attention to your body. Keep track of your symptoms, take your medications on schedule, and stay in touch with your healthcare team. Many people with heart conditions can still enjoy a full and active life with proper management.

Lifestyle tips

• Follow a heart-healthy diet like the Mediterranean diet (rich in fish, olive oil, nuts, and vegetables)
• Aim for at least 150 minutes of moderate activity each week (brisk walking, swimming, dancing) – ask your doctor what's safe for you
• Keep a healthy weight
• Manage stress through meditation, deep breathing, or talking to friends
• Get enough sleep (7–8 hours a night)
• Avoid or limit alcohol and quit smoking

Diet and exercise

Eating well is key – focus on whole foods, limit processed foods and salt. Exercise, even light activity like walking or chair exercises, helps your heart work more efficiently. Always check with your doctor before starting a new exercise program, especially if you have a heart condition.

Mental health and emotional wellbeing

Living with a heart condition can be stressful and sometimes lead to feelings of anxiety or depression. It's normal to feel worried. Talk to your doctor or a counsellor. Staying connected with family and friends helps. If you feel very low or have thoughts of harming yourself, contact your local crisis support or emergency services.

Prevention

While you can't stop aging, you can reduce your risk of heart problems. A healthy lifestyle – good diet, regular activity, not smoking, and managing stress – makes a big difference. Keeping blood pressure, cholesterol, and diabetes under control also helps.

Vaccines

Staying up to date with vaccines, like the flu shot and pneumonia vaccine, can protect against infections that might stress your heart. Ask your doctor about recommended vaccines for your age and health.

Screening programmes

Regular check-ups with your GP can catch problems early. They may check your blood pressure, cholesterol, and blood sugar. If you have a family history of heart disease, you might be offered additional screening like an ECG or heart scan.

Complications

If left untreated

• Heart attack or stroke
• Heart failure (when the heart can't pump enough blood)
• Irregular heart rhythms (arrhythmias) that can be serious
• Blood clots, which can travel to the brain or lungs
• Kidney damage (from poor circulation)
• Reduced quality of life due to symptoms like fatigue and shortness of breath

Long-term outlook

The outlook for older adults with heart conditions is often good, especially when problems are found early and managed well. Many people can live active, fulfilling lives with the right treatment and lifestyle changes. Working closely with your healthcare team can help you stay as healthy as possible for as long as possible.
