How Lung Disease Impacts Your Heart: Understanding the Connection with Dr. Jasdeep Sidana

As we go about our daily lives, we seldom consider the importance of our lungs and heart in maintaining our overall health. These two organs work together to supply oxygen to our bodies and keep us alive. However, when we suffer from lung disease, it can significantly impact our heart’s health, leading to a range of complications.

In this blog, we’ll explore the connection between lung disease and the heart, its complications, and prevention measures with the help of Dr. Jasdeep Sidana, a pulmonologist.

Understanding Lung Disease

Lung disease is a broad term that describes various conditions that affect the lungs, including chronic obstructive pulmonary disease (COPD), asthma, and lung cancer. According to Dr. Jasdeep Sidana, smoking is the leading cause of lung disease in the United States. Other factors that can lead to lung disease include air pollution, occupational exposure to dust, and genetics.

The Heart-Lung Connection

To understand how lung disease affects the heart, knowing how these two organs work together is essential. The lungs supply oxygen-rich blood to the heart, which pumps it to the rest of the body. However, when the lungs are affected by the disease, they cannot provide enough oxygen to the heart, leading to an increased workload on the heart. This can cause cardiovascular complications, including pulmonary hypertension and cor pulmonale.

Major Cardiovascular Complications of Lung Disease

According to Dr. Jadsdeep Sidana, several different types of lung diseases can affect your heart health. Some of them are the following:

  • Emphysema: This disease is a progressive condition in which the air sacs in the lungs become damaged or destroyed over time. As these air sacs become blocked by mucus or inflamed by smoke particles, they cannot hold as much oxygen when you breathe in. This lack of oxygen causes stress on your heart as it works harder to pump blood throughout your body, leading to an increased risk of heart attack and stroke. 
  • Asthma: Asthma can also affect your heart health if not properly managed. Asthma is a chronic inflammatory disorder of the lungs that impacts how quickly you can exhale air from your lungs; this decreased airflow makes it difficult for oxygenated blood to reach all parts of the body—including the heart—which can ultimately lead to an increased risk for cardiovascular disease and other associated conditions such as arrhythmias (irregular heartbeat), high cholesterol levels, and hypertension (high blood pressure). 
  • Pulmonary Hypertension: Dr. Jasdeep Sidana explains that pulmonary hypertension is a condition where the blood pressure in the pulmonary arteries (the arteries that supply blood to the lungs) becomes high, leading to strain on the heart. Symptoms of pulmonary hypertension include shortness of breath, chest pain, and fatigue. Treatment options for pulmonary hypertension include medications and lifestyle changes.
  • Cor Pulmonale: Cor pulmonale is a condition where the right side of the heart is enlarged due to lung disease. According to Dr. Jasdeep Sidana, common causes of cor pulmonale include COPD and pulmonary embolism. Symptoms of cor pulmonale include swelling in the legs, shortness of breath, and fatigue. Treatment options include medications and oxygen therapy.

Preventing Cardiovascular Issues Caused By Lung Disease

Fortunately, there are ways in which you can reduce your risk of developing cardiovascular issues due to lung disease. According to Dr. Sidana, preventing cardiovascular issues caused by lung disease involves managing the underlying lung disease and adopting healthy lifestyle habits that promote heart health. Here are some tips:

  1. Quit smoking: Smoking is a significant lung and heart disease risk. Quitting smoking can improve lung function and reduce the risk of heart disease.
  2. Manage lung disease: Work with your healthcare provider to manage your lung disease and keep it under control. This may involve taking medications, oxygen therapy, pulmonary rehabilitation, or other treatments.
  3. Exercise regularly: Regular exercise can improve lung function, strengthen the heart, and reduce the risk of heart disease. Consult with your healthcare provider before starting an exercise program.
  4. Eat a heart-healthy diet: Consuming a diet rich in fruits, vegetables, whole grains, and lean proteins can help reduce the risk of cardiovascular issues. It is important to avoid foods that are high in saturated and trans fats, sodium, and added sugars.
  5. Manage stress: Chronic stress can increase the risk of heart disease. Focus on healthy ways to cope up and help take your mind away from your triggers. These may include activities such as exercise, relaxation techniques, or talking with a mental health professional.
  6. Get regular check-ups: Regular check-ups with your healthcare provider can help detect any changes in lung function or signs of heart disease early on.

By taking these steps, you can reduce the risk of developing cardiovascular issues caused by lung disease and improve your overall health and well-being.


Lung disease can significantly impact your heart’s health, leading to a range of complications. However, understanding the connection between these two organs and taking preventative measures can help reduce your risk of complications. Dr. Jasdeep Sidana emphasizes the importance of early detection and treatment of lung disease and caring for your heart’s health. If you have concerns about your lung or heart health, seek the advice of a qualified healthcare professional.
