COPD vs CHF: Difference and Comparison

Due to our modern way of living, millions of people are affected by many severe diseases daily. COPD, or Chronic Obstructive Pulmonary Disease and CHF or Congestive Heart Failure, are two diseases where two particular organs of the human body suffer from severe damage. Though both of these diseases share a few common factors, they differ in many ways.

Key Takeaways

  1. COPD (chronic obstructive pulmonary disease) primarily affects the respiratory system, whereas CHF (congestive heart failure) impacts the heart’s ability to pump blood.
  2. COPD results from long-term exposure to lung irritants like cigarette smoke, while multiple factors, including hypertension, coronary artery disease, and heart attacks, can cause CHF.
  3. Treatment for COPD focuses on managing symptoms and preventing complications, while CHF treatment aims to improve heart function and manage underlying conditions.


The difference between COPD and CHF is that COPD causes damage to the lungs, whereas CHF is a disease of the heart. Though there are a few common causes of both of these diseases, such as smoking, pollution, obesity etc., the causes, risk factors, and treatments are different from each other.


COPD is a short form of a disease called Chronic Obstructive Pulmonary Disease. It is a long-term disease as it takes a lot of time to develop in the lungs of the patients. It badly affects the lungs, and the damage cannot be undone. However, there are several treatments available to provide relief to patients.

CHF is a term for Congestive Heart Failure. It causes damage to the heart where the heart ceases to produce oxygen, and as a result, it leads to its failure. If the underlying causes of heart failure are revealed and treated well, the patient will be able to lead a normal life. Thus, the patients can be cured completely.

What is COPD?

COPD, or Chronic Obstructive Pulmonary Disease, is a severe lung disease. This disease develops over a long period of time. It is a type of obstructive pulmonary disease where the airflow is obstructed. Thus the air supply to the lungs will be stopped, and the patient can die in that situation.

This disease is not singular in nature. It includes a group of diseases. They are Emphysema, Chronic Bronchitis, and Irreversible Asthma. Most of the patients have both emphysema and chronic bronchitis. The patients with COPD gradually start having difficulty in breathing. They suffer from severe limitation of airflow and inflammation.

The major cause of COPD is smoking cigarettes. Though long-term exposure to second-hand smoke or irritants such as pollution, dust and workplace fume can also cause this disease. Even biomass exposure, such as wood smoke, can also contribute to causing this disease. It becomes very difficult to diagnose this as it does not show any symptoms at first. By the time the patient develops this disease, he or she starts experiencing symptoms like shortness of breath, chest tightness etc.

Fatigue, weight loss and muscle loss are the common symptoms in the early stage of COPD. It is predominantly found in men and women older than 40 years. However, no cure has been found till now. But one can take steps to feel better.


What is CHF?

CHF, or Congestive Heart Failure, is a disease where a patient suffers from heart failure. In this state, the pumping power of one’s heart becomes weaker than normal. The blood flow gradually comes down, and on the other hand, the pressure in the heart increases. As a result, the heart becomes congested and stops working.

In this disease, the heart fails to pump enough oxygen to meet the body’s demands. It can be said that there are two types of heart failure. The first one includes the Left Atrium and the Left Ventricle, which means the Left Side heart failure. The second is the Right Side heart failure, including the Right Atrium and Right Ventricle.

There can be many reasons behind heart failure. It can happen due to systolic dysfunction, or the inability of the heart to contract and push out the blood, and diastolic dysfunction or the inability of the heart to relax. Due to CHF, a patient can experience severe damage to his health.

This disease can damage the heart muscles, causing CAD (Coronary Artery Disease), heart attack, hypertension, obesity and diabetes etc. In order to properly treat Congestive Heart Failure, the patient must focus on modifying his or her lifestyle, such as losing weight, smoking cessation, exercising, limiting alcohol intake and having a healthier diet.

Main Differences Between COPD and CHF

  1. COPD is a severe disease of the lungs. On the other hand, CHF is a disease of the heart. 
  2. COPD is an umbrella term for a group of diseases. It is not a single disease. But CHF is a particular heart disease. 
  3. The causes of both of these diseases differ from each other. COPD can happen due to second-hand smoke, pollution, dust, biomass etc. But CHF can happen in either two conditions- if the heart stops pushing out blood or ceases to relax. 
  4. COPD cannot be cured. But there are many ways to relieve the pain of the patients. But CHF is completely treatable if patients are treated correctly. 
  5. It is very difficult to detect COPD in patients as it is a long-term disease. On the other hand, CHF can be diagnosed easily.
