Heart Failure in Older Adults

Plain-language information about heart failure in older adults. This page is for older Canadians and their caregivers. It does not replace advice from your own health-care provider.

1. What is heart failure?

Important to understand

Heart failure means the heart is not pumping blood as well as it should to meet the body's needs. It does not mean the heart has stopped.

When the heart is weaker or stiffer than normal:

Common signs and symptoms

Shortness of breath, especially with activity or when lying flat
Tiredness and weakness
Swelling in the ankles, feet, legs, or belly
Needing to urinate more at night
Sudden weight gain from fluid build-up

2. Why heart failure matters more in older adults

Heart failure is more common in older adults and can cause:

For older adults

Because many older adults also have high blood pressure, diabetes, kidney disease, or lung disease, managing heart failure often requires careful balancing of medications, fluids, and activity.

3. How doctors usually treat heart failure

Health-care providers often consider:

Treatment commonly includes:

Medications

Help the heart pump, relax blood vessels, remove extra fluid

Salt & fluid management

Limiting salt, watching fluid intake if advised

Daily monitoring

Tracking weight and symptoms

Devices (some cases)

Pacemakers or defibrillators if recommended

Important

This website does not tell you which medications, doses, or devices are right for you. Only your heart specialist or primary provider can decide that.

4. Common types of heart failure medicines in older adults

Health-care providers often use several medications together:

Diuretics ("water pills")

Help remove extra fluid and reduce swelling and breathlessness

ACE inhibitors or ARBs

Help relax blood vessels and reduce strain on the heart

Beta blockers

Help slow the heart rate and reduce its workload

Mineralocorticoid receptor antagonists

Such as spironolactone – help remove salt and may protect the heart

Newer heart failure medications

Used in certain situations based on current guidelines

Regular monitoring

Your provider will often check your blood pressure, pulse, weight, swelling, and blood tests (kidney function, electrolytes) to ensure your medications are working safely.

5. Possible side effects older adults may notice

Things to watch for and report include:

Feeling very dizzy or light-headed, especially when standing up
Feeling much more tired or weak than usual
Very slow or very fast heartbeat
New or worse confusion
Muscle cramps or weakness
Less urination than usual, or very dark urine
New or worsening cough, or trouble breathing
Swelling in legs, ankles, or belly that is getting worse

Do not stop suddenly

Do not stop your heart medications suddenly unless your provider tells you to. Stopping some heart medications without medical advice can be dangerous.

6. Habits and lifestyle that may help

Many heart failure guidelines suggest that certain daily habits may help manage symptoms along with medical care. What is safe and realistic is different for each person.

Food and salt (sodium)

Fluids

Important

Some people with heart failure are given a fluid limit. Follow the instructions from your health-care provider. Do not restrict fluids unless you have been specifically told to do so.

Movement and activity

Always ask first

Always ask your health-care provider which food and fluid changes are safe for you, and what types of activity are safe. Do not change salt, fluids, or exercise without checking first.

7. When to call your doctor, nurse practitioner, or heart failure clinic

(Non-urgent)

Contact your health-care provider if:

Sudden weight gain

More than your provider has told you is safe (often 2–3 lbs in a day or 5 lbs in a week)

More swelling

In your legs, ankles, or belly than usual

More short of breath

Doing your regular activities

Need more pillows

To sleep because of breathlessness

Medication confusion

Unsure how to take or adjust your medications

8. When to call 911 or go to the emergency department

Call 911 immediately if:

  • You are struggling to breathe, even at rest
  • You have chest pain or pressure that does not go away
  • You wake up suddenly feeling like you cannot catch your breath
  • Your lips or fingers look blue or grey
  • You feel like you are going to faint, or you do faint

If possible, do not drive yourself. Ask someone to call for you or call an ambulance.

9. Questions to ask your doctor or nurse practitioner

You can print these questions and bring them to your next appointment:

What type of heart failure do I have, and how severe is it?
What are the goals of my treatment at my age and health?
What should I do if my weight or swelling goes up suddenly?
Which symptoms mean I should call you, and which mean I should go to the emergency department?
How should I manage salt and fluids in my diet?
What activities or exercise are safe for me?
How do my heart medications interact with my other medicines?
