Congestive Heart Failure
Understanding Congestive Heart Failure (CHF)
Congestive Heart Failure (CHF) is a condition where the heart cannot pump blood effectively, causing fluid to build up in the lungs and other parts of the body. Symptoms include shortness of breath and swelling.
What is Heart Failure?
What Happens
- Heart muscle becomes weak or stiff
- Heart muscle cannot pump enough blood to meet the body's needs for blood and oxygen
- Less blood is pumped with each heartbeat
- Blood backs up in blood vessels
- Fluid leaks into tissues
- Body doesn't get enough oxygen
Common Causes
- Coronary artery disease
- High blood pressure
- Damage due to heart attack
- Diseases of the heart muscle (cardiomyopathies)
- Inflammation of the heart muscle (myocarditis)
- Heart valve problems
- Congenital heart defects
Types of Heart Failure
Systolic Heart Failure
Heart muscle is weak and can't contract well
- Left sided heart failure
- Reduced ejection fraction (HFrEF)
- Heart cannot pump enough blood into circulation
Diastolic Heart Failure
Heart muscle is stiff and can't fill well
- Left sided heart failure
- Preserved ejection fraction (HFpEF)
- Heart doesn't relax normally due to stiffness
- Heart cannot fill with blood like it should during the time between each beat
Right Sided Heart Failure
- Typically caused by left sided heart failure Left side of heart fails and cannot pump enough blood out
- Increased fluid pressure pushed back through lungs and damages the right side of heart
- Blood backs up in veins
Signs and Symptoms
What to watch for
Call Your Doctor Immediately If You Have:
- Sudden severe shortness of breath
- Chest pain
- Rapid weight gain (2-3 lbs in 1 day)
- Fainting or near-fainting
- Severe swelling in legs or abdomen
- Persistent cough with pink/white foam
- Rapid or irregular heartbeat
- Confusion or difficulty thinking
Breathing Problems
- Shortness of breath during activity
- Trouble breathing when lying flat
- Waking up short of breath
- Persistent cough
Fluid Retention
- Swelling in feet, ankles, legs
- Rapid weight gain
- Abdominal swelling
- Decreased urination
Other Symptoms
- Fatigue and weakness
- Dizziness
- Loss of appetite
- Difficulty concentrating
Treatment
How heart failure is managed
Lifestyle Changes
- Low-sodium diet (less than 2000mg/day)
- Fluid restriction if recommended
- Regular, gentle exercise
- Weight monitoring
- Quit smoking
- Limit alcohol
Medications
- ACE inhibitors and Angiotensin Receptor Blockers (ARBs): Lower blood pressure and reduce heart's workload
- Angiotensin Receptor Neprilysin Inhibitor (ARNI): replaces ACE/ARB, improves artery opening and blood flow, reduces sodium retention, decreases strain on the heart
- Beta-blockers: Slow heart rate, reduce workload
- Aldosterone antagonists: Diuretic that reduces blood pressure and improves heart function
- Sodium glucose cotransporter-2 inhibitors (SGLT2): help control blood sugar, first used in diabetics but also help with improving cardiac function and helping with HF symptoms
- Digoxin: Helps to reduce fast heart rate, helps with heart's ability to contract
- Diuretics: Remove excess fluid ("water pills")
Advanced Treatments
- Pacemakers or defibrillators
- Cardiac resynchronization therapy
- Heart valve repair/replacement
- Ventricular assist devices
- Heart transplant (severe cases)
Self-Management
Taking care of yourself at home
Daily Weight Monitoring
- Weigh yourself every morning
- Use the same scale, same time
- Weigh after using bathroom, before eating
- Keep a weight log
- Call doctor if you gain 2-3 lbs in 1 day or 5 lbs in 1 week
Medication Management
- Take medications exactly as prescribed
- Don't skip doses
- Use a pill organizer
- Know what each medication does
- Don't stop without talking to doctor
Activity Guidelines
- Stay as active as possible
- Start slowly and build up
- Stop if you feel short of breath
- Balance activity with rest
- Ask about cardiac rehabilitation
