// 01 · understanding your condition

What is congestive heart failure?

CHF doesn't mean your heart has stopped working — it means it isn't pumping as efficiently as it should. Fluid can build up in your lungs, legs, and abdomen as a result. Understanding what's happening helps you manage it.

🫀
The basic problem
Your heart muscle is weakened or stiff and can't pump blood forward efficiently. Blood backs up, causing fluid to leak into surrounding tissues.
🫁
Left-sided CHF
The left side of your heart fails to pump blood out to the body. Fluid backs up into the lungs, causing shortness of breath — especially lying flat.
🦵
Right-sided CHF
The right side can't pump blood into the lungs. Fluid backs up into the body — causing leg swelling, ankle edema, and abdominal bloating.
📉
Ejection fraction (EF)
Your EF measures how much blood your heart pumps out with each beat. Normal is 55–70%. An EF below 40% is considered reduced (HFrEF); above 50% with symptoms is preserved (HFpEF).
📈
Common causes
Coronary artery disease, high blood pressure, heart attack, diabetes, valve problems, or cardiomyopathy. Often, it's more than one cause working together.
🔄
It's manageable
CHF is chronic, but most people live well with it. The keys: daily monitoring, medications, diet, exercise, and knowing when to call your care team.

// 02 · recognizing symptoms

Symptoms to know and watch.

Some symptoms are expected with CHF. Others are warning signs that your heart is struggling and need immediate attention. Learn the difference.

COMMON CHF SYMPTOMS
  • ◆ Shortness of breath — especially with activity or lying flat
  • ◆ Swelling in ankles, feet, or legs (edema)
  • ◆ Rapid or irregular heartbeat
  • ◆ Persistent cough or wheezing, sometimes with pink-tinged mucus
  • ◆ Fatigue and weakness — especially with minimal exertion
  • ◆ Sudden weight gain (2–3 lbs overnight or 5 lbs in a week)
  • ◆ Decreased ability to exercise or do daily activities
  • ◆ Nausea, lack of appetite, or abdominal bloating
  • ◆ Difficulty concentrating or confusion (low cardiac output)
  • ◆ Needing to sleep with extra pillows (orthopnea)
SIGNS YOU ARE STABLE
  • ◆ Weight is stable day-to-day (within 2 lbs)
  • ◆ Swelling is minimal and not getting worse
  • ◆ Breathing comfortably at rest and with light activity
  • ◆ Energy levels are consistent
  • ◆ Sleeping comfortably without extra pillows
  • ◆ Urine output is normal (diuretics working)
  • ◆ Heart rate is in your target range
  • ◆ Blood pressure is within your prescribed limits
🚨
Call 911 immediately for any of these:
Sudden severe shortness of breath · Chest pain or pressure · Fainting or near-fainting · Coughing up pink or bloody mucus · Heart rate over 130 at rest · Signs of stroke (face drooping, arm weakness, speech difficulty)
⚠️
Call your doctor same day for:
Weight gain of 2+ lbs overnight or 5+ lbs in a week · Increasing swelling in legs or feet · Shortness of breath that is getting worse · New or worsening cough · Feeling more tired than usual with no clear reason · Dizziness or lightheadedness
// 03 · daily monitoring

Monitor daily. Catch problems early.

Daily self-monitoring is the single most effective thing you can do to stay out of the hospital. Small changes caught early prevent big crises later.

01
Weigh yourself every morning — same time, same conditions
Step on the scale every morning after using the bathroom and before eating or drinking. Wear the same amount of clothing each time. Record the number. Weight gain means fluid is accumulating — even before you feel it.
02
Know your weight action plan
Most care teams use a "traffic light" system: Green = within 2 lbs of dry weight (stable). Yellow = gained 2–3 lbs overnight or 5 lbs in a week — call your nurse or doctor. Red = gained more than 5 lbs in 2 days — call immediately or go to ER. Ask your care team for your specific targets.
03
Check your blood pressure daily
Use a home blood pressure cuff — sit quietly for 5 minutes first. Take it at the same time each day. Target range varies by patient, but typically systolic (top number) should stay between 90–140. Ask your doctor for your specific limits. Log both numbers each day.
04
Check your heart rate
A resting heart rate between 60–100 bpm is generally normal for CHF patients, though your target may differ based on your medications. A pulse over 100 at rest or under 50 — especially with symptoms — should prompt a call to your care team.
05
Check your legs and ankles for swelling
Every morning, press your finger into your shin for 5 seconds and release. If an indent (pit) remains, that's pitting edema — a sign of fluid buildup. Note whether it's getting better or worse each day. Report worsening edema to your care team.
06
Keep a daily log
A simple notebook or phone note works fine. Record: date, weight, blood pressure, heart rate, swelling (none / mild / moderate / severe), symptoms, and fluid intake. Bring this log to every appointment — it helps your care team spot trends and adjust your plan.
// 04 · diet & fluid management

What you eat and drink matters enormously.

Diet is one of the most powerful tools for managing CHF. Sodium causes your body to retain water. Too much fluid puts direct strain on your heart. Small changes make a large difference.

2,000
MG SODIUM DAILY LIMIT
Standard CHF target. Some patients are restricted to 1,500 mg. Ask your doctor for your specific limit.
1.5–2L
DAILY FLUID LIMIT
About 6–8 cups. Includes water, juice, coffee, soup, ice cream, and anything that's liquid at room temperature.
↓
SODIUM = LESS SWELLING
Reducing sodium is often more effective than increasing diuretic dose at controlling fluid retention.
HIGH SODIUM — AVOID OR LIMIT
  • ✕ Table salt and sea salt — remove the shaker from the table
  • ✕ Canned soups, beans, and vegetables (unless labeled "no salt added")
  • ✕ Deli meats, bacon, sausage, hot dogs
  • ✕ Frozen dinners and packaged meals
  • ✕ Fast food — nearly all items exceed daily sodium limit in one meal
  • ✕ Pickles, olives, soy sauce, teriyaki, most condiments
  • ✕ Cheese (especially processed cheese)
  • ✕ Bread and rolls (often high in hidden sodium)
  • ✕ Salted nuts and chips
HEART-FRIENDLY CHOICES
  • ✓ Fresh or frozen vegetables (no added salt)
  • ✓ Fresh fruits — especially potassium-rich (banana, orange, melon)
  • ✓ Fresh or frozen fish and skinless chicken
  • ✓ Whole grains — oatmeal, brown rice, whole wheat bread (low-sodium)
  • ✓ Unsalted nuts and seeds
  • ✓ Herbs and spices instead of salt — garlic, lemon, cumin, rosemary
  • ✓ Dried beans and lentils (cooked from scratch, no added salt)
  • ✓ Olive oil for cooking
  • ✓ Low-sodium labels = less than 140 mg per serving
💧
Counting your fluids
Everything liquid counts — water, coffee, tea, juice, milk, broth, ice (melted), gelatin, ice cream, popsicles. A practical method: fill a pitcher each morning with your daily limit. As you drink throughout the day, pour the same amount out of the pitcher. When the pitcher is empty, you've hit your limit.
🥤
Managing thirst
Thirst is harder to control when you're limiting fluids. Try: sucking on ice chips (small amounts count as fluid, but feel more satisfying), sugar-free hard candy or gum to stimulate saliva, rinsing your mouth with cold water without swallowing, and staying cool — heat increases thirst.
// 05 · activity & cardiac rehab

Move more. Safely.

Exercise is medicine for CHF — it strengthens your heart muscle, reduces symptoms, and improves quality of life. The key is progressing at the right pace. Rest is not the same as recovery.

PHASE 1
Hospital / Acute
Days 1–7 post-admission
Bed mobility, sitting at the edge of the bed, standing with assist, slow walking in the hallway. Goal is to prevent deconditioning. All activity monitored by clinical staff.
PHASE 2
Early Recovery
Weeks 1–6 at home
Short walks (5–10 min), light household tasks, gradual increase in distance. Rest between activities. Avoid stairs in first 1–2 weeks if possible. Follow your home health PT or OT plan.
PHASE 3
Outpatient Cardiac Rehab
Weeks 6–18
Supervised exercise program at a cardiac rehab facility, typically 3x/week. Heart rate, blood pressure, and oxygen levels monitored throughout. Resistance training added gradually. Most effective long-term intervention for CHF.
PHASE 4
Long-Term Maintenance
Ongoing
150 minutes of moderate activity per week (e.g., 30 min walks, 5 days/week). Light resistance training 2x/week. Always warm up and cool down. Listen to your body every single day.
→
Safe target heart rate: Exercise at a pace where you can still hold a conversation. Most CHF patients target 50–70% of max HR. Your cardiologist will give you specific limits — always follow those first.
→
Rating of perceived exertion: Use the Borg scale — aim for 3–4 out of 10 during activity (moderate, but not breathless). Never push through chest pain, severe shortness of breath, or lightheadedness.
→
Warning signs — stop activity: Chest pain or tightness · Shortness of breath that doesn't resolve in 5 min of rest · Dizziness or near-fainting · Heart rate above your target · Sudden severe fatigue. Sit or lie down and call for help if symptoms persist.
→
Don't exercise if: You gained 2+ lbs overnight · Resting heart rate is over 100 · You have new or worsening swelling · You feel significantly worse than your baseline. Call your care team first.
→
Cardiac rehab referral: Ask your cardiologist for a formal cardiac rehab referral — it is covered by Medicare and most insurance. Studies show it reduces hospitalizations and improves survival. Don't skip it.
🚶
Walking is your best starting point
Start with 5–10 minutes once daily. Add 1–2 minutes every few days if feeling well. Build to 30 continuous minutes over 4–6 weeks. Walk at the same time each day so it becomes a habit. Morning walks are often best — cooler air and lower exertion demands before the day begins.
// 06 · medications

Your medications. What they do.

Most CHF patients take several medications. Understanding what each one does — and why it matters — makes it easier to take them consistently. Never stop or change a dose without calling your doctor first.

Drug class Common examples Brand names (examples) What it does for your heart
ACE Inhibitors Lisinopril, Enalapril, Ramipril Zestril, Vasotec, Altace Relaxes blood vessels, lowers blood pressure, reduces the heart's workload. Slows CHF progression.
ARBs Losartan, Valsartan, Candesartan Cozaar, Diovan, Atacand Similar to ACE inhibitors — used when ACE inhibitors cause a persistent cough. Protects the heart and kidneys.
ARNIs Sacubitril/Valsartan Entresto Newer class — combines two mechanisms to reduce strain on the heart. Shown to significantly reduce hospitalizations and death in HFrEF.
Beta-blockers Carvedilol, Metoprolol succinate, Bisoprolol Coreg, Toprol-XL, Zebeta Slows the heart rate, lowers blood pressure, and protects the heart muscle from overstimulation. Do not stop suddenly.
Diuretics ("water pills") Furosemide, Torsemide, Bumetanide Lasix, Demadex, Bumex Removes excess fluid from the body through urine. Reduces swelling and breathing difficulty. Take in the morning to avoid nighttime bathroom trips.
Aldosterone Antagonists Spironolactone, Eplerenone Aldactone, Inspra Reduces fluid retention and protects the heart. Requires monitoring of potassium levels. Avoid bananas and oranges in large amounts if prescribed this.
SGLT2 Inhibitors Dapagliflozin, Empagliflozin Farxiga, Jardiance Originally developed for diabetes — now a cornerstone of CHF treatment. Reduces hospitalizations and mortality regardless of diabetes status.
Digoxin Digoxin Lanoxin Strengthens the heart's contractions and slows heart rate. Requires regular blood level monitoring. A very narrow therapeutic range — take exactly as prescribed.
Blood thinners Warfarin, Apixaban, Rivaroxaban Coumadin, Eliquis, Xarelto Prevents blood clots — often prescribed if CHF is accompanied by atrial fibrillation or history of clots. Requires careful monitoring and consistency.
⚠️
Critical medication rules
Never skip doses · Never stop a medication without talking to your doctor first (especially beta-blockers — stopping suddenly can cause a dangerous rebound) · Keep an up-to-date medication list and bring it to every appointment · Tell every provider — including dentists — all medications you take · Avoid NSAIDs (ibuprofen, naproxen, Advil, Aleve) — they cause fluid retention and can worsen CHF significantly · Use acetaminophen (Tylenol) for pain relief instead, and only as directed.

Supporting someone with CHF.

Caring for someone with CHF is both meaningful and demanding. You play a critical role in their recovery. Here's how to help effectively — and how to care for yourself too.

⚖️
Help with daily weigh-ins
Be there for the morning weigh-in. Help record the number and compare to the previous day. Know the action plan — when is a weight gain an emergency call vs. a watch-and-wait?
🍽️
Take on meal planning
Reading nutrition labels and preparing low-sodium meals is much easier when a caregiver takes the lead. Remove the salt shaker. Cook from scratch when possible. Learn which restaurant orders are safer.
💊
Medication management
Help set up a daily pill organizer. Keep the medication list updated. Know what each medication is for and what to watch for. Attend appointments when possible to hear guidance directly.
🚶
Walk together
Walking with your loved one increases motivation and safety. Start slow. Know the warning signs to stop. Celebrate consistency — not speed or distance.
📋
Keep the log
Help maintain the daily monitoring log. Bring it to every appointment. Trends in weight, blood pressure, and symptoms over weeks are more useful to doctors than a single number.
🧘
Take care of yourself
Caregiver burnout is real. Ask for help. Accept help. Connect with a support group. Your wellbeing directly affects the quality of care you can provide — it is not selfish to prioritize it.

// 09 · living well with CHF

Long-term. Living well.

CHF is a long-term condition, but most people with CHF live meaningful, active lives. These habits — built consistently over time — make the difference.

→
Keep every appointment. Cardiology, primary care, and home health visits all serve a purpose. Between visits, communicate with your team — don't wait for the next scheduled appointment if something changes.
→
Don't smoke. Smoking constricts blood vessels, reduces oxygen delivery, and dramatically accelerates heart disease. If you smoke, ask your care team about cessation resources — quitting is the single highest-impact thing you can do for your heart.
→
Limit alcohol. Alcohol weakens the heart muscle and interacts with many CHF medications. Most cardiologists recommend complete avoidance or strict limits (no more than 1 drink/day for women, 2 for men — and only if your doctor approves).
→
Manage stress actively. Stress increases cortisol and adrenaline, which raise blood pressure and heart rate. Techniques that help: deep breathing, meditation, gentle yoga, time outdoors, consistent sleep, and social connection.
→
Sleep and rest well. Elevate the head of your bed 6–8 inches if breathing is worse lying flat. Maintain a consistent sleep schedule. Talk to your doctor if you're tired despite adequate sleep — sleep apnea is very common in CHF and worsens the condition significantly if untreated.
→
Watch the weather. Extreme heat causes blood vessels to dilate and the heart to work harder. Extreme cold constricts them. Both can trigger CHF symptoms. Stay indoors during heat advisories. Dress in layers in cold weather. Avoid very hot baths or saunas.
→
Flu and pneumonia vaccines. Respiratory infections can rapidly worsen CHF. Get a flu shot every year and the pneumococcal vaccine as recommended. COVID-19 vaccination is also strongly recommended — respiratory illness from any source stresses a weakened heart.
→
Stay connected. Social isolation is independently linked to worse heart outcomes. Stay in contact with family and friends. Consider a CHF support group — hearing from others managing the same condition reduces anxiety and improves adherence to treatment.
