Understanding a Chronic Condition Where the Heart Struggles to Pump Efficiently

Heart Failure (HF) is a long-term medical condition in which the heart cannot pump blood effectively enough to supply the body with the oxygen and nutrients it needs. It doesn’t mean the heart has stopped, but that its pumping ability has weakened. Heart failure may affect the left side, right side, or both sides of the heart, and its severity can vary from mild to advanced stages.

Types of Heart Failure

Ayesha Heart Care – Understanding Heart Conditions Clearly

1. Left-Sided Heart Failure

This occurs when the left ventricle, the main pumping chamber of the heart, cannot push blood properly into the body.

a. Systolic Heart Failure (HFrEF)

The heart muscle becomes weak and cannot contract forcefully, reducing its ability to pump blood.

b. Diastolic Heart Failure (HFpEF)

The left ventricle becomes stiff and cannot fill with enough blood during relaxation, leading to inadequate blood flow.

2. Right-Sided Heart Failure

In this condition, the right ventricle fails to pump blood efficiently to the lungs for oxygenation.

It often results from left-sided heart failure due to increased pressure in the lungs, but it may also be caused by:

  • Pulmonary hypertension

  • Chronic lung diseases such as COPD

3. Congestive Heart Failure (CHF)

CHF refers to the stage where fluid builds up in the lungs, liver, abdomen, or legs because the heart cannot pump effectively. The term “congestive” refers to this fluid accumulation.

4. Acute vs. Chronic Heart Failure
Acute Heart Failure

Appears suddenly and usually requires emergency care (e.g., heart attack, sudden arrhythmia).

Chronic Heart Failure

A long-term, progressive condition that develops gradually over time.

Causes of Heart Failure
Common Reasons Seen at Ayesha Heart Care

Heart failure usually develops when the heart is weakened or damaged. Major causes include:

  • Coronary Artery Disease (CAD): Blocked arteries reduce blood flow to the heart muscle.

  • High Blood Pressure: Forces the heart to work harder, eventually weakening it.

  • Heart Attack: Damages heart muscles and reduces pumping ability.

  • Cardiomyopathy: Heart muscle disease caused by genetics, infections, alcohol, or medications.

  • Valve Diseases: Faulty heart valves disrupt normal blood flow.

  • Arrhythmias: Irregular heartbeats make pumping inefficient.

  • Diabetes: Increases the risk of heart disease and failure.

  • Thyroid Disorders: Both overactive and underactive thyroids affect the heart.

  • Congenital Defects: Birth defects in the heart structure.

  • Chronic Lung Conditions: COPD and pulmonary diseases strain the heart, especially the right side.

Symptoms of Heart Failure
Signs You Should Not Ignore

  • Shortness of Breath: During activity, lying down, or at night.

  • Fatigue & Weakness: Due to reduced oxygen supply.

  • Swelling (Edema): In legs, ankles, feet, or abdomen.

  • Rapid or Irregular Heartbeats: Heart tries to compensate for weak pumping.

  • Cough or Wheezing: Caused by fluid in the lungs.

  • Limited Exercise Capacity: Easily tired or breathless with activity.

  • Sudden Weight Gain: From fluid retention.

  • Poor Appetite / Nausea: Reduced blood flow to the digestive system.

  • Confusion: In severe cases, reduced blood flow affects brain function.

Diagnosis of Heart Failure
How Ayesha Heart Care Identifies the Condition

To diagnose heart failure, the doctor evaluates symptoms and performs tests such as:

  • Physical Examination: Checking for fluid buildup, abnormal sounds, and vital signs.

  • Echocardiogram: Ultrasound to assess heart size, motion, and pumping strength.

  • ECG (Electrocardiogram): Detects electrical abnormalities or irregular rhythms.

  • Blood Tests:

    • BNP test: High levels indicate heart failure.

    • Tests for liver and kidney function.

  • Chest X-ray: Shows fluid in lungs or enlarged heart.

  • Cardiac MRI / CT: Detailed imaging of heart structure and function.

Stages of Heart Failure
ACC/AHA Classification

  • Stage A: High risk but no symptoms (e.g., hypertension, diabetes, family history).

  • Stage B: Structural changes in the heart but no symptoms.

  • Stage C: Heart failure with visible symptoms.

  • Stage D: Advanced heart failure requiring specialized treatments like transplant or mechanical support.

Treatment Options for Heart Failure
Ayesha Heart Care Approach

Treatment aims to reduce symptoms, improve daily life, and prevent further heart damage.

Lifestyle Modifications

  • Low-Sodium Diet: Reduces fluid buildup.

  • Regular Exercise: Customized according to patient ability.

  • Daily Weight Checks: Helps detect early fluid retention.

  • Quit Smoking & Limit Alcohol: Protects heart health.

Medications Commonly Used

  • ACE Inhibitors: Reduce heart workload.

  • ARBs: Alternative for patients intolerant to ACE inhibitors.

  • Beta-Blockers: Slow heart rate and improve function.

  • Diuretics: Remove excess fluid.

  • Aldosterone Antagonists: Help control fluid and sodium.

  • SGLT2 Inhibitors: Improve heart failure outcomes.

  • Digoxin: Helps regulate heart rhythm.

  • Vasodilators: Relax blood vessels.

Device Therapies

  • ICD (Implantable Cardioverter Defibrillator): Prevents dangerous arrhythmias.

  • CRT (Cardiac Resynchronization Therapy): Improves coordination of heartbeats.

Surgical and Advanced Options

  • Heart Transplant: For end-stage heart failure.

  • LVADs (Left Ventricular Assist Devices): Mechanical pumps used as temporary or long-term support.

Prevention of Heart Failure
How to Reduce Your Risk

  • Control blood pressure

  • Manage diabetes & cholesterol

  • Eat a balanced, low-salt diet

  • Exercise regularly

  • Avoid smoking and excess alcohol
