Heart failure is a serious medical condition where the heart is unable to pump enough blood to meet the body’s needs. Despite the term “failure,” it doesn’t mean the heart has completely stopped working—it means the heart’s function is impaired. This condition can develop gradually over time or occur suddenly, requiring immediate medical attention.

Millions of people worldwide live with heart failure. With early diagnosis, the right treatment plan, and lifestyle adjustments, many patients can manage the condition effectively and maintain a good quality of life.

What Is Heart Failure?

Heart failure, also known as congestive heart failure, occurs when the heart’s pumping power is weaker than normal. When the heart can’t supply enough blood and oxygen to the body’s organs, symptoms develop and can worsen over time.

The condition can affect:

• Left side of the heart: Affects the body’s ability to receive oxygen-rich blood.
• Right side of the heart: Impacts the return of blood from the body to the lungs.
• Both sides: In severe or advanced cases, both sides of the heart may be affected.

Types of Heart Failure

Heart failure is classified into several types based on the affected area and pumping ability:

1. Systolic Heart Failure (HFrEF)

Occurs when the left ventricle loses its ability to contract normally, reducing the amount of blood the heart pumps out.

2. Diastolic Heart Failure (HFpEF)

Happens when the left ventricle becomes stiff and can’t relax properly, making it harder to fill with blood.

3. Right-Sided Heart Failure

Often a result of left-sided failure, it causes fluid buildup in the legs, abdomen, and liver due to poor blood return from the body.

What Causes Heart Failure?

Many underlying conditions can weaken or damage the heart over time. Common causes include:

• Coronary artery disease (CAD)
• High blood pressure (hypertension)
• Heart attack (myocardial infarction)
• Cardiomyopathy (damaged heart muscle)
• Heart valve disease
• Arrhythmias (irregular heartbeat)
• Diabetes
• Congenital heart defects
• Obesity
• Excessive alcohol or drug use

Controlling these risk factors significantly reduces the chances of developing heart failure.

Heart failure symptoms vary depending on the type and severity but often include:

• Shortness of breath during activity or while lying down
• Fatigue and weakness
• Swelling in legs, ankles, or abdomen (edema)
• Rapid or irregular heartbeat
• Persistent cough or wheezing
• Weight gain from fluid retention
• Reduced exercise tolerance
• Frequent urination at night
• Lack of appetite and nausea

If you experience multiple symptoms, consult a healthcare professional promptly.

Diagnosing heart failure typically involves:

• Medical history and physical exam
• Blood tests (BNP or NT-proBNP to check heart stress)
• Chest X-ray (to detect fluid in the lungs)
• Echocardiogram (ultrasound to check heart function)
• Electrocardiogram (ECG) (to monitor heart rhythm)
• MRI or CT scan (for detailed imaging)

Accurate diagnosis helps determine the best course of treatment and management.

While heart failure is a chronic condition, many treatment options are available to manage symptoms and improve heart function.

1. Medications

• ACE inhibitors or ARBs: Help relax blood vessels
• Beta-blockers: Lower heart rate and blood pressure
• Diuretics: Reduce fluid buildup
• Aldosterone antagonists: Help remove excess sodium
• Digitalis: Strengthens heart contractions

2. Lifestyle Changes

• Adopt a low-sodium, heart-healthy diet
• Maintain a healthy weight
• Get regular exercise (as approved by a doctor)
• Avoid tobacco and limit alcohol
• Monitor fluid intake
• Weigh yourself daily to detect fluid retention early

3. Devices and Surgery

• Pacemakers and ICDs: Regulate or restore normal heart rhythm
• Heart valve repair/replacement
• Bypass surgery or angioplasty
• Heart transplant (for severe cases)

With the right treatment and consistent follow-up, people living with heart failure can enjoy a fulfilling life. It’s important to:

• Take medications exactly as prescribed
• Monitor symptoms and report any changes
• Stay active while respecting physical limits
• Follow a structured diet and track fluid intake
• Stay connected with a healthcare team for ongoing care

Can Heart Failure Be Prevented?

You can reduce your risk of heart failure by:

• Managing high blood pressure and diabetes
• Eating a balanced, low-sodium diet
• Exercising regularly
• Avoiding smoking and excessive alcohol
• Controlling cholesterol levels
• Getting regular health checkups

Heart health is within reach with proactive care and early intervention.
