Congestive heart failure (CHF) is a serious condition affecting millions worldwide. This comprehensive guide will help you understand its causes, recognize symptoms, and explore treatment options.
What is Congestive Heart Failure?
Congestive heart failure occurs when the heart muscle doesn’t pump blood as efficiently as it should. This can result from various underlying conditions, leading to two main types of heart failure:
- Heart Failure with Reduced Ejection Fraction (HFrEF): The heart becomes weak and doesn’t squeeze effectively.
- Heart Failure with Preserved Ejection Fraction (HFpEF): The heart squeezes normally but is stiff and doesn’t relax properly.
Common Causes
- Heart attacks (myocardial infarction)
- Viral infections affecting the heart muscle
- Leaky or tight heart valves
- High blood pressure
- Coronary artery disease
Recognizing Symptoms
Early detection is crucial. Watch for these signs:
- Shortness of breath (dyspnea), especially during activity
- Swelling in legs, ankles, and feet (edema)
- Fatigue and weakness
- Rapid or irregular heartbeat
- Persistent cough or wheezing
- Increased need to urinate at night
- Sudden weight gain from fluid retention
- Difficulty sleeping flat (orthopnea)
- Lack of appetite and nausea
Seek medical attention if you experience these symptoms, especially if they worsen over time.
Diagnosis
Your healthcare provider may use the following to diagnose CHF:
- Physical examination
- Medical history review
- Blood tests (including BNP or NT-proBNP)
- Electrocardiogram (ECG)
- Echocardiogram
- Chest X-ray
- Stress tests
- Cardiac MRI or CT scan
Treatment Options
Treatment aims to improve quality of life, reduce symptoms, and slow disease progression. Options include:
Medications:
- ACE inhibitors or ARBs
- Beta-blockers
- Diuretics
- Aldosterone antagonists
- Sacubitril/valsartan (Entresto)
- SGLT2 inhibitors (e.g., empagliflozin, dapagliflozin)
Lifestyle Changes:
- Limiting salt and fluid intake
- Regular exercise (as recommended by your doctor)
- Quitting smoking
- Managing stress
Devices and Surgical Interventions:
- Implantable cardioverter-defibrillators (ICDs)
- Cardiac resynchronization therapy (CRT)
- Ventricular assist devices (VADs)
- Heart valve repair or replacement
- Coronary bypass surgery
Ongoing Monitoring:
- Regular check-ups
- Self-monitoring of symptoms and weight
