Your dad has been more tired lately. His ankles are puffy by evening, he gets winded walking to the mailbox, and he's started sleeping in his recliner because lying flat makes him cough. At his last appointment, the doctor used the words "congestive heart failure." The phrase sounds frightening, and you aren't sure what it means for him or for you.
Heart failure is a condition in which the heart can't pump enough blood to meet the body's needs1. It's common in older adults, and it usually gets worse over time, but treatment and daily habits can ease symptoms, keep people out of the hospital and help them live better6. This guide explains what families need to know, from early symptoms to the last stage of life. It's general information. Always follow your parent's care team.
What congestive heart failure is
In heart failure, the heart muscle is too weak or too stiff to pump blood as well as it should1. Blood and fluid can back up into the lungs, belly, legs and feet. That fluid buildup is where the word "congestive" comes from7.
Common causes in older adults include coronary artery disease and past heart attacks, long-term high blood pressure, diabetes, heart valve disease and irregular heart rhythms such as atrial fibrillation8. Aging itself changes the heart and blood vessels, which is one reason heart failure becomes more common with age8.
Types and stages of heart failure
Doctors describe heart failure in a few ways. Left-sided heart failure is the most common and often causes fluid in the lungs. Right-sided heart failure tends to cause swelling in the legs, feet and belly1. Doctors also talk about whether the heart muscle is weak and pumps too little with each beat, or stiff and doesn't fill properly. Both are common in older adults, and treatment differs somewhat between them6.
Heart failure is often described in stages, from being at risk to advanced disease, and by how much symptoms limit daily activity. Ask the doctor which type and stage your parent has, and what the latest heart tests show. Knowing this helps you understand the treatment plan and what changes to watch for.
Symptoms of heart failure in older adults
- Shortness of breath. During activity at first, later at rest or when lying flat2.
- Tiredness and weakness. Everyday tasks like dressing or showering become exhausting.
- Swelling. In the feet, ankles, legs or belly, from fluid buildup2.
- Quick weight gain. From fluid, sometimes several pounds in a few days2.
- Coughing or wheezing. Especially at night or when lying down.
- Needing extra pillows. Or sleeping in a chair to breathe more easily.
- Confusion or poor appetite. Older adults sometimes show less typical signs, like new confusion, nausea or feeling full quickly.
In older adults, symptoms are easy to blame on age or another illness. If you notice a change, tell the doctor. Our guides to an elderly parent sleeping a lot and dehydration in older adults cover other common causes of fatigue and confusion.
Warning signs to act on
Ask your parent's doctor for a written plan that says when to call and when to go to the emergency room. In general:
- Call the doctor the same day for a quick weight gain, such as two to three pounds in a day or five pounds in a week, or the amount your parent's plan says.
- Call for more swelling, more shortness of breath, a new cough, or needing more pillows to sleep.
- Call if dizziness, a fast or uneven heartbeat, or very low urine output appears.
Catching fluid buildup early can often prevent a hospital stay.
How heart failure is treated
Treatment aims to ease symptoms, slow the disease and help your parent stay active6. It usually combines:
- Medicines. Several kinds of medicines help the heart work better, lower blood pressure, slow the heart rate and remove extra fluid. Water pills (diuretics) are common for swelling and breathlessness6.
- Treating the cause. Such as managing blood pressure, diabetes, valve problems or rhythm problems.
- Devices or procedures. Some people benefit from a pacemaker, a defibrillator or other procedures6.
- Cardiac rehabilitation. A supervised program of exercise, education and support. Medicare covers it for people with stable chronic heart failure who meet the rules4.
- Lifestyle changes. Limiting salt, staying active, not smoking and managing weight3.
Older adults often take many medicines. Ask the doctor or pharmacist to review all of them, including over-the-counter pain relievers, since some can make heart failure worse. Heart failure and kidney disease often occur together; see our guide to kidney failure in the elderly.
Daily care at home: how families can help
- Weigh every morning. Same time, same scale, after using the bathroom and before breakfast. Write it down3.
- Help with medicines. Use a pill organizer, and don't skip water pills because of bathroom trips. Ask about timing instead.
- Watch the salt. Many canned soups, deli meats, frozen meals and restaurant foods are very salty. Read labels together.
- Follow fluid advice. Some people are told to limit fluids. Ask the doctor what's right for your parent.
- Keep moving. Short walks and gentle activity, as the doctor allows, help strength and mood3.
- Prevent infections. Ask about flu, COVID-19 and pneumonia vaccines, since infections can trigger a flare.
- Plan rest. Space out tasks and use a shower chair to save energy.
Swelling, water pills and tiredness raise the risk of falls. See fall prevention for older adults. If your parent needs nursing visits after a hospital stay, read does Medicare pay for home health care and home care vs. home health.
Eating well with heart failure
Food is a big part of daily life with heart failure. Most people are asked to limit sodium, because salt makes the body hold on to water3. Cooking at home with fresh foods, herbs and spices makes this easier. Older adults with heart failure often lose their appetite, especially when fluid presses on the stomach, so smaller, more frequent meals can help. If your parent is losing weight without trying, mention it to the doctor, since fluid can hide muscle loss on the scale. A dietitian can make a plan that fits your parent's tastes, budget and other conditions such as diabetes or kidney disease.
Where your parent will get the best care
Many people with heart failure live at home with family support, home care aides for daily tasks, and home health nurses after hospital stays. As needs grow, families sometimes consider assisted living, where staff help with medicines and meals, or a nursing home when skilled care is needed every day. Ask any community how it handles daily weights, low-salt meals and medicine changes from the cardiologist. See assisted living vs. nursing home and medication management in assisted living for questions to ask.
After a hospital stay
The weeks after a heart failure hospital stay are a high-risk time. Before discharge, make sure you know the new medicine list, the target weight, the warning signs and the date of the follow-up visit, ideally within a week or two. Ask whether home health or cardiac rehab is planned. Our hospital discharge planning guide has a checklist. Bring the medicine bottles from home to the first follow-up visit so the doctor can compare them with the discharge list. Mix-ups between old and new prescriptions are common after a hospital stay, and catching them early helps prevent another admission. If your parent lives alone, plan for someone to check in daily during the first two weeks.
Mood, memory and daily life
Living with a long-term illness can be hard emotionally. Depression and anxiety are common in people with heart failure and can make it harder to keep up with self-care3. Watch for loss of interest, poor sleep or withdrawal, and mention them to the doctor. See depression in older adults.
Some older adults with heart failure also have memory problems, which can make managing medicines and diet harder. A family member, home care aide or assisted living staff may need to take over these tasks.
End-stage heart failure: what to expect
Over time, heart failure often progresses despite treatment. In the advanced stage, families may notice7:
- Shortness of breath even at rest, and trouble lying flat.
- More frequent hospital stays for fluid buildup.
- Poor appetite, weight loss and muscle wasting.
- Extreme tiredness and sleeping much of the day.
- Low blood pressure, making some medicines hard to take.
- Confusion, especially when blood flow to the brain drops.
Heart failure often follows an up-and-down path, with sudden flares and partial recovery, so it can be hard to know how much time remains. Our guide to end-of-life signs in the elderly describes the final weeks and days.
Palliative care and hospice
Palliative care focuses on comfort and quality of life and can be given alongside treatment at any stage. It can help with breathlessness, fatigue, anxiety and hard decisions9. Hospice is for people whose doctor certifies a life expectancy of six months or less if the illness runs its normal course5. Medicare contractors look at things like symptoms at rest despite treatment when judging hospice eligibility for heart disease10.
If your parent has an implanted defibrillator, talk with the care team about turning off its shock function near the end of life, so it doesn't deliver painful shocks. See hospice vs. palliative care and what hospice provides.
Planning ahead as a family
Talk with your parent about their wishes while they can share them: what matters most, which treatments they would or wouldn't want, and where they hope to be cared for. Put those wishes in writing with an advance directive11. See advance directive vs. living will.
Caring for someone with heart failure can be demanding. Ask for help early, and take breaks. Our guide to caregiver burnout has ideas.
