Are you dealing with a cough that won’t go away? Most people assume a cough means a cold or throat infection, but sometimes it can signal something more serious — a problem with your heart. According to Dr. Ajay Bahadur, the Best Cardiologist in Lucknow, a persistent cough can be an early warning sign of heart failure, especially when it happens at night or when you lie down.
Many people ignore these symptoms, thinking it’s a seasonal issue, but your body might actually be asking for help. Understanding how a heart-related cough works can help you take action before it becomes dangerous.
What Is a Cardiac (Heart) Cough?
A cardiac cough happens when your heart is too weak to pump blood properly. This usually occurs in left-sided heart failure.
Here’s what happens inside your body:
- When your left ventricle can’t pump blood well, pressure builds up in your lungs.
- This pressure forces fluid into the lungs, making it harder to breathe.
- The body tries to remove this fluid by triggering a cough.
As Dr. Ajay Bahadur, the best cardiologist in Lucknow, explains:
“It’s like a blocked drain. When the heart doesn’t pump properly, blood backs up into the lungs, causing a cough and breathlessness.”
Heart Cough vs. Normal Cough – How to Tell the Difference
| Feature | Heart Cough | Cold/Allergy Cough |
| Mucus | Frothy, white, or pinkish | Thick yellow or green |
| When it happens | Worse at night or lying down | Any time of day |
| Relief | Improves when sitting upright | May not change much |
| Other Symptoms | Shortness of breath, tiredness, leg swelling | Fever, sore throat, runny nose |
| Sound | Wet and heavy | Dry or wheezing sound |
If your cough gets worse when you lie flat or you find relief after sitting up, it could be a sign of heart trouble.
Key Symptoms of Heart Cough
If your cough is heart-related, you might also notice:
- Coughing more at night or needing extra pillows to sleep comfortably.
- Suddenly waking up gasping for air after sleeping for a while.
- Pink or frothy mucus, which can mean fluid is entering your lungs.
- Shortness of breath even during light activity.
- Swelling in your legs, ankles, or feet.
- Extreme tiredness and lack of energy.
These signs together often point to heart failure, not a simple cold.
Chest Pain and Cough – When to Worry
Sometimes coughing can cause mild muscle pain in your chest — this is usually harmless. But if your chest pain feels heavy, tight, or pressing, it could be a sign of a heart problem such as angina or even a heart attack. In such cases, it’s important to seek medical help immediately.
How Doctors Diagnose a Heart-Related Cough
At advanced cardiac centres, the diagnosis is done with a few key tests:
- Physical Check-Up: Listening for abnormal heart or lung sounds.
- Chest X-Ray: To see if there’s fluid in the lungs or if the heart looks enlarged.
- ECG (Electrocardiogram): To check heart rhythm and electrical activity.
- Echocardiogram (Echo): A heart ultrasound to see how well the heart pumps blood.
- Blood Test (BNP): Measures a hormone that increases when the heart is under stress.
These tests help confirm whether the cough is linked to heart failure or not.
Treatment – Fixing the Cause, Not Just the Cough
As Dr. Ajay Bahadur, the Best Cardiologist in Lucknow, says:
“The goal is to treat the heart, not just the cough. Once the heart improves, the cough disappears.”
Treatment may include:
- Diuretics (Water Pills): To remove extra fluid from the body.
- ACE Inhibitors or ARBs: To help relax blood vessels and reduce pressure.
- Beta-Blockers: To slow the heart rate and let it rest.
- Lifestyle Changes: Reducing salt, managing fluid intake, and regular check-ups.
When heart failure is properly managed, symptoms like cough and breathlessness greatly improve.
Conclusion: Listen to What Your Cough Is Saying
A long-lasting cough that worsens at night shouldn’t be ignored. It might be your heart trying to get your attention.
If you notice coughing along with shortness of breath, fatigue, or leg swelling — consult Dr. Ajay Bahadur, the best cardiologist in Lucknow, right away.
Early diagnosis and treatment can make a huge difference. Remember — when it comes to your heart, timing is everything.
