Elderly Parent With Heart Failure: Warning Signs, Daily Weights

If your parent has heart failure, the most useful thing the family can do is a daily weigh-in: every morning, same scale, after urinating and before breakfast, written down. A sudden gain often means fluid is building up, sometimes before your parent feels worse. MedlinePlus says to contact the provider for a gain of more than 2 to 3 pounds in a day or 5 pounds in a week, but your parent's own care team sets the number that applies to them. Severe shortness of breath, chest pain that won't stop or fainting means 911.

The morning weigh-in, the same way every day

The American Heart Association's lifestyle guidance for heart failure gives the routine: weigh at the same time each morning, before breakfast and after urinating, in the same type of clothes, no shoes, on the same scale in the same location. Write it down and bring a copy to every appointment. MedlinePlus says the same.

The Heart Failure Society of America's self-care booklet, Module 4 (an older booklet, copyright 2014), explains why the sameness matters: change the routine and the weight can move by 2 or more pounds, which is the size of a warning sign.

The same booklet makes two more points:

• Fluid can hide. HFSA says the average person can hold about 8 to 15 extra pounds of fluid before swelling shows.
• Compare with the dry weight, not yesterday. Dry weight is your parent's weight without extra fluid. HFSA suggests writing down the weight on the morning after they come home from the hospital, since that is probably the dry weight, and otherwise asking the doctor or nurse.

A few things that help an older parent stick with it:

• Leave the scale in one spot near the toilet, so the order becomes bathroom, scale, kitchen.
• Keep the log and a pen right beside it. A log in a drawer gets filled in from memory on Friday.
• If you live far away, ask for the number by text each morning. It doubles as a "she's up" check.

How much weight gain means a call

Reputable sources don't agree on the numbers:

The AHA pages are the most recent of these. All of them are written for everyone, and your parent isn't everyone. Ask the cardiologist or heart failure nurse, "At what gain, over how many days, do you want a call?" Then write that answer at the top of the log.

Weight loss counts too. MedlinePlus says to call for a lot of weight lost, and HFSA's medications booklet says water pills can remove too much fluid, and that thirst or dizziness from dehydration means a call.

Green, yellow and red: the self-check zones

The AHA's online Self-Check Plan sorts symptoms into three levels, labeled "Excellent," "Pay Attention, Use Caution" and "Medical Alert, Warning." The AHA tool doesn't name colors. Mayo Clinic's page on heart failure action plans describes the AHA plan as green, amber and red zones, and the table below uses green, yellow and red as shorthand. If your parent's clinic gives you its own zone sheet, use theirs.

In the AHA's tool, the middle level says symptoms "may indicate a need to contact your doctor or healthcare team." The top level says to call the physician or 911 because "you need to be evaluated right away."

Two rows deserve a family member's eye. The same AHA page says a caregiver or relative may notice confusion first. And sleep changes can hide: Dad moving to the recliner "because it's comfortable" may mean he can't breathe lying flat. MedlinePlus lists needing more pillows, or waking short of breath an hour or two after falling asleep, as reasons to call.

When to call the doctor, and when to call 911

HFSA's Module 4 splits symptoms into three groups.

Call 911 if your parent has:

• Chest discomfort or pain lasting more than 15 minutes that isn't relieved by rest or nitroglycerin
• Severe, persistent shortness of breath
• Fainted or passed out

Call the doctor immediately for:

• Increasing shortness of breath, or new shortness of breath at rest
• Waking at night struggling to breathe, or needing to sleep sitting up or on more pillows
• A racing or irregular heartbeat that persists and makes them dizzy or lightheaded
• Coughing up frothy or pink sputum, or feeling like they may pass out

Call the doctor or nurse soon for what HFSA calls early symptoms, such as the weight change above, new swelling, a cough that won't go away, more fatigue, nausea, confusion or dizziness.

Your parent's team may draw the lines differently. MedlinePlus's questions to ask the doctor include: "When should I call the provider? When should I call 911 or the local emergency number?" Ask it at the next visit and write the answer on the zone sheet.

If you aren't sure, and your parent is struggling to breathe, has chest pain, or isn't making sense, call 911. An ambulance that turns out not to be needed is a fine outcome.

Salt and fluid: your parent's doctor sets the numbers

Use the sodium and fluid limits your parent's doctor gives, not ones from the internet. MedlinePlus's fluids and diuretics page says the provider "may ask you to limit your daily sodium intake to 1500 to 2300 mg per day," and its discharge page says that as heart failure gets worse, some people are asked to limit fluids to 6 to 9 cups (1.5 to 2 liters) a day. The NHLBI's living with heart failure page says you "may also be asked" to limit salt and liquids.

Write the actual numbers on the log, and ask whether soup and ice cream count as fluid.

The water pill is the other piece. MedlinePlus says to take diuretics at the same time every day and not at night before bed. HFSA's medications booklet says not to take an extra dose of a diuretic or potassium without asking the provider first, and Module 4 says to follow the doctor's diuretic instructions for weight gain if they've given them, and otherwise to call. Don't start, stop or change a dose on your own. If your parent has a written "if your weight goes up by this much, take this" plan, it belongs in the binder word for word.

Sick days, heat and the medicine cabinet

Vomiting, diarrhea or not eating

A stomach bug can be a bigger deal on water pills, since they can already cause dehydration. HFSA's medications booklet also says people shouldn't take an SGLT2 inhibitor, a newer class of heart failure medicine, during prolonged periods without eating, including during illness. Those are questions for the team, not decisions to make at home. If your parent's team has written sick-day rules, put them in the binder. If not, ask now, while everyone is well: "If Mom has vomiting or diarrhea, which medicines does she keep, which does she hold, and when do we call?"

Hot weather

The CDC's heat and medications guidance lists diuretics among commonly prescribed medicines that raise risk from heat, says an ACE inhibitor or ARB taken with a diuretic may significantly increase that risk, and tells clinicians to consider adjusting fluid restrictions on hot days. Its older adults page says that on fluid limits or water pills, ask the doctor how much to drink in hot weather. Our heat wave guide has more.

Over-the-counter medicines to ask about

HFSA's medications booklet says people with heart failure should be particularly cautious about NSAIDs, which include aspirin, ibuprofen and naproxen, because they can cause kidney problems and worsen heart failure. It says acetaminophen is generally preferable for aches, pain or fever. MedlinePlus explains that NSAIDs make the body hold on to sodium. If your parent takes an aspirin their doctor prescribed, don't stop it on your own; ask. Check acetaminophen doses with the doctor or pharmacist too.

In a 2019 AHA News article, a news story rather than formal guidance, a preventive cardiologist named heart failure among the biggest concerns with decongestants such as pseudoephedrine and phenylephrine, and the article notes that blood pressure guidelines suggest alternatives such as nasal saline or antihistamines. It also says both decongestants and NSAIDs are found in many cold medicines, so read the active ingredients or hand the box to the pharmacist.

For supplements, MedlinePlus says not to take any other medicines or herbs without asking first.

What to tell paramedics and the ER

Your parent may be too breathless to answer questions, so keep this on one page:

• The diagnosis, in the doctor's words, such as heart failure with reduced or preserved ejection fraction.
• Ejection fraction, if known, with the date. The AHA's ejection fraction page says a normal heart's EF is between 55% and 70%, and that you can have heart failure with a normal EF. Copy the number from the last echo report.
• The diuretic: name, dose, and when the last dose was taken, plus any doses added or skipped this week.
• The weights. Dry weight, this morning's weight and the week's trend. "Up 4 pounds since Sunday" says more than any single number.
• Devices. The NHLBI's treatment page lists a biventricular pacemaker, a ventricular assist device and an implantable cardioverter defibrillator among devices some people may need if heart failure with reduced ejection fraction gets worse. Note the type, maker and device clinic number; our pacemaker card guide covers the ID card.
• Every other medicine, including over-the-counter pills and supplements.
• Cardiologist or heart failure clinic, the last hospital stay, allergies, and any POLST or advance directive.

Our emergency information sheet for paramedics shows how to fit this on one page, and the medication list guide covers the full list. For the bag itself, see what to bring to the ER.

A simple weight and symptom log

One line a day, on a sheet taped near the scale:

The rows are made up. At the top of the sheet, write the dry weight, the call threshold from your parent's doctor, the sodium and fluid limits, and the office and after-hours numbers.

When symptoms change, MedlinePlus suggests asking whether your parent ate something different or missed a medicine. That's what the notes column is for.

What to keep in the heart failure binder

• The clinic's zone sheet, or the AHA's printable self-check plan, with the call threshold filled in
• Dry weight and the date it was set
• Sodium and fluid limits, including the hot-weather answer
• Any written diuretic adjustment plan, and the sick-day answer
• Current medication list, with diuretic dose and timing
• Ejection fraction and date, device ID card copy and device clinic number
• Cardiologist, heart failure nurse and after-hours numbers
• Recent logs and the last hospital discharge papers
• POLST or advance directive, and the health care proxy's name

After a hospital stay, start the log on the first morning home. Our hospital discharge checklist covers the rest of that day.

Frequently asked questions

How much weight gain is a concern with heart failure?

Most of the sources above say to call for a gain of about 2 to 3 pounds in a day or about 5 pounds in a week, and the AHA's self-check flags even 2 to 3 pounds in a week as a reason for caution. Your parent's care team should give their personal number.

Can a person with heart failure take ibuprofen?

Ask the doctor first. HFSA says NSAIDs such as ibuprofen can cause kidney problems and worsen heart failure, and that acetaminophen is generally preferable.

If you'd rather not build this from scratch

You can build this yourself with a notebook and one good conversation at the next cardiology visit. Or Emergency Binder Now can organize it from about 25 minutes of guided questions into a printable binder with your parent's medicines, conditions, doctors and contacts, a one-page Emergency Information Sheet for paramedics and the ER, and a list of what's still missing, like the dry weight nobody has written down yet. You can see a sample binder first.

This article is general information, not medical advice. Your parent's weight thresholds, sodium and fluid limits, diuretic instructions and sick-day plan come from their own doctor or heart failure team.
