Are your lungs filled with water? Let's learn about this heart-related condition (Cardiogenic Pulmonary Edema)!

Do you sometimes feel a little short of breath? Or do you wake up from sleep because you have difficulty breathing when you go to bed? Maybe your legs are also swollen. If you have symptoms like these, it is not a good idea to ignore it. Because, this is a condition that involves the heart and fills the lungs with water, which can be life-threatening . Today, we will talk about this condition called `(Cardiogenic Pulmonary Edema)`.

What is this heart-related swelling in the lungs called? (Cardiogenic Pulmonary Edema)

Simply put, `(Cardiogenic Pulmonary Edema)` is an unnecessary accumulation of fluid in your lungs . This can be very dangerous. The main reason for this is that the pressure on the left side of the heart increases and blood accumulates. Most often, this happens due to heart failure. When the lungs fill with water like this, in addition to difficulty breathing, other organs in the body can also be damaged by not getting enough oxygen . Think of it, our lungs are like a sponge. When it absorbs water, it cannot function properly. That's how it is.

What is the difference between cardiac edema and pulmonary edema?

Both of these names refer to fluid buildup in your lungs, making it difficult to breathe. However, `(Cardiogenic Pulmonary Edema)` is a type of `(Pulmonary Edema)` that is caused by a heart problem . That is, it is part of the larger category `(Pulmonary Edema)`. On the other hand, `(Non-cardiogenic Pulmonary Edema)` is caused by damage to the lungs themselves. For example, it can be caused by something like a severe infection or inhaling toxic gases.

So what are cardiac edema and renal edema?

Both of these actually refer to the accumulation of fluid in our organs. In `(Cardiac Edema)`, excess fluid is in the lungs. But in `(Renal Edema)`, excess fluid is in the kidneys. Sometimes, both of these conditions can occur due to heart failure. If there is a problem with the kidneys, the kidneys are not able to properly filter fluid from the blood and excrete it as urine. Then, water accumulates in the body.

Who is at higher risk of developing cardiac edema due to heart disease?

This condition often affects people with heart disease , especially those with weak heart function (Heart Failure). Just think, heart disease is common in our country too. So, if you also have any heart-related problems, it is very important to take care of this.

What are the symptoms of this? How do we recognize it?

See if you have one or more of these characteristics:

• Do you have difficulty breathing when you exercise or lie down? Some people have difficulty breathing when lying down in bed, so they have to sleep with two or three pillows elevated.
• Do you suddenly wake up at night feeling short of breath? This is something that many people experience.
• Are your feet and ankles swelling? To the point where it's hard to put on your shoes.
• Do you always feel tired and exhausted? Like you don't have the energy to do anything?
• Are you suddenly gaining more than one kilogram (about two pounds) of weight per day? This could be due to water retention.

If you have symptoms like these, it is best to seek medical advice without wasting time .

Why is this happening? What are the reasons for this?

The main cause of `(Cardiogenic Pulmonary Edema)` is `(Congestive Heart Failure ).` This is a condition in which the heart is unable to pump enough blood to the body. In addition, there are several other causes:

• Arrhythmia : The heart does not beat in a proper rhythm.
• Cardiomyopathy : Weakening or thickening of the heart muscle.
• Problems with the valves on the left side of the heart : For example, narrowing of the valves, or regurgitation.
• Heart Attack: A sudden blockage of an artery that supplies blood to the heart.

Simply put, when the heart's pumping efficiency decreases, blood gradually begins to build up in the lungs, exerting pressure. That's when the lungs fill with water.

How does a doctor diagnose this?

When you go to see a doctor, the first thing he or she does is:

• A physical exam is a thorough examination of you. They will listen to your chest with a stethoscope and check to see if your legs are swollen.
• Asking about your medical history . Things like previous illnesses you've had, whether anyone in your family has heart disease, etc.
• Testing is the process of performing several special tests .

What tests are done for this?

After the doctor examines you, they may perform the following tests to confirm the exact condition:

• ECG (Electrocardiogram) : This can monitor the electrical activity of the heart, that is, the rhythm of the heart beat.
• Chest X-ray : An X-ray of the chest is taken to check for fluid in the lungs or an enlarged heart.
• Echocardiogram : This is like an ultrasound scan of the heart. It can check many things about the heart, such as its size, shape, how its valves are working, and how it pumps.
• Blood Tests : Some components of the blood, for example, enzymes released when the heart is damaged, and kidney function are tested.
• Pulmonary Arterial Catheter : This is not a test for everyone. It is a bit complicated. It is a test that involves inserting a small tube through the neck or groin to measure the pressure in the blood vessels leading to the lungs.

Well, what are the treatments for this?

Treatment methods depend on the cause and severity of the disease. There are several main treatment methods:

Surgeries and specific treatments:

In some cases, treatment such as this may be necessary:

• PCI (Percutaneous Coronary Intervention) : If there is a blockage in the blood vessels of the heart, it is opened by inflating them with a balloon and possibly inserting a `Stent` (a small mesh-like device).
• Ventricular Assist Device (VAD) : A small device that is implanted inside or outside the body that helps the heart pump blood.
• Heart Valve Replacement : If there is a serious problem with the heart valves, it is a valve replacement surgery.
• Coronary Artery Bypass Graft (CABG) : We all know "bypass surgery". It involves creating new blood vessels in the heart to bypass blocked blood vessels.
• Intra-aortic Balloon Pump (IABP) : A balloon that is temporarily inserted into a blood vessel to help pump blood to the heart.
• Extracorporeal Membrane Oxygenation (ECMO) : This is a method used in very severe cases. It involves adding oxygen to the blood using a machine outside the body and returning it to the body.
• Heart Transplant : A last resort if all other treatments fail.

Types of drugs:

Your doctor may prescribe you medications such as:

• Vasodilators : These work by widening blood vessels, making it easier for the heart to pump blood.
• Diuretics : We usually call these "water pills." They work by removing excess fluid from the body through urine.

The most important thing is that if you have heart failure, your doctor will tell you to reduce your salt intake . This doesn't just mean the salt you put in your food, but also hidden salt in things like canned food, packaged soups, and sauces. So you need to be careful about that too.

Lifestyle changes and things you can do at home:

These things will also help you:

• Exercise at least a few days a week. Even a light walk is good. However, ask your doctor what exercises are right for you.
• Keep your swollen legs slightly elevated while sitting.
• If your legs are swollen, you can wear special socks called ``Compression Stockings'' as advised by your doctor.
• If you have fluid in your lungs, keep the head of the bed slightly elevated while sleeping.

What can we do to reduce this risk?

Cardiogenic Pulmonary Edema (CPED) often occurs when you already have a heart problem. So, the best way to reduce this risk is to keep your heart healthy and strong .

These things will help with that:

• Eat foods low in saturated fats and trans fats . Include more vegetables, fruits, and legumes in your diet.
• Exercise whenever possible. Even walking for 30 minutes a day is a great thing.
• Completely avoid the use of tobacco products (cigarettes, beedis, etc.).
• Limit your alcohol consumption. It's best to stop completely if possible.

What happens if this happens? Can it be cured?

In fact, `(Pulmonary Edema)` is a life-threatening condition . However, your recovery rate depends on the cause of it. For example, about 50% of people with `(Cardiac Edema)` survive for a year after being discharged from the hospital.

Heart failure is a common cause of this. It is a chronic disease, meaning it lasts a long time. However, with proper treatment, this condition can be well controlled .

Instead of feeling sorry, "Oh, I got this disease," what's important is to follow the doctor's instructions and adjust your lifestyle.

How do I take care of myself?

Weighing yourself at the same time every day can help you see if your condition is getting worse. It's best to weigh yourself first thing in the morning, before eating, and after using the bathroom. If your weight is increasing by more than one kilogram (about two pounds) a day, it's likely that you're retaining water. If this happens, tell your doctor right away.

When should I see a doctor?

If you experience any of these symptoms, definitely see a doctor:

• If you have difficulty breathing , either when you are a little tired or when you are lying down.
• If you wake up from sleep with shortness of breath .
• If your legs are swollen .

Don't ignore these symptoms. The sooner you start treatment, the better.

When do you need to go to the Emergency Treatment Unit (ETU) ?

If you are having difficulty breathing or are experiencing severe chest pain , do not wait. Call 911 (or 1990 Sudhana Ambulance Service in Sri Lanka) immediately or go to a hospital with someone.

What are the important questions to ask the doctor?

When you go to see the doctor, don't forget to ask these questions. That way, you too can get a better understanding of your condition.

• "Doctor, why have I developed this `(Cardiac Edema)` condition?"
• "Can this be cured by treating the cause?"
• "What changes do I need to make in my lifestyle?"

The earlier your doctor diagnoses your condition and starts treatment, the better the outcome. That's why it's important to see your family doctor regularly for checkups. That way, you can catch any heart problems before they get worse. It's also important to take your medications on time.

Finally, I have to say... (Take-Home Message)

So, `(Cardiogenic Pulmonary Edema)` is a condition where the lungs fill with water due to a heart problem, and it is something to be concerned about. If you have symptoms like difficulty breathing, swelling of the legs, or waking up gasping for breath , pay attention to it.

Early detection, proper treatment, and a healthy lifestyle are the best ways to protect yourself from and control this condition. Take care of your heart, because it is your lifeblood!
