Top 10 Signs of Heart Failure

Because the symptoms of heart failure (sometimes called congestive heart failure) can be difficult to identify and describe, it is often diagnosed quite late. If you or the person you're caring for has risk factors for heart disease, such as being a smoker or a former smoker and having high blood pressure or coronary artery disease (CAD), it's a good idea to be on the lookout for heart failure. Taken by themselves, any one of the symptoms listed here probably isn't cause for alarm, but two or more are good cause to call your doctor for an evaluation.

1. Shortness of breath, particularly when sleeping or lying down

One of the characteristic symptoms of heart failure is waking during the night or in the morning feeling as if you can't breathe deeply or can't catch your breath.

What it feels like: A feeling of compression in the chest and lungs, making it difficult to take a deep breath, particularly during exertion or when lying down. Other clues: difficulty sleeping because of breathing difficulties or choosing to sleep in a chair or recliner because it's more comfortable. This symptom is easily confused with other sleep problems and breathing problems, such as COPD and sleep apnea, but the difference is the feeling of being short of breath when lying down. Having to sit up to catch one's breath is particularly telling. Many heart failure patients compensate by propping themselves up on pillows to sleep; when making a diagnosis, doctors sometimes ask their patients how many pillows they sleep on.

Why it happens: Because the heart's ability to pump is weakened, blood backs up in the blood vessels that return blood from the lungs to the heart, causing fluid to leak into the lungs. When the head is elevated, gravity helps ease blood flow to and from the lungs, reducing the feeling of breathlessness.

2. A feeling of chest pressure or "drowning"

People diagnosed with heart failure often look back and recognize this early symptom but didn't know what was happening when they first experienced it, or had difficulty describing it.

What it feels like: It may feel like a pressure or heaviness in the chest, or a feeling akin to drowning or being compressed by a heavy weight. It may also feel as if the lungs are filled with fluid when trying to take a deep breath. Some people with heart failure experience chest pain, but not everyone does, so a lack of pain doesn't rule out heart failure.

Why it happens: Fluid overload throughout the body affects both the chest cavity and the lungs. Fluid in the lungs can feel like drowning when drawing a breath, and congestion in the chest and abdominal tissues can make the lungs feel pressure from outside, as they might deep under water.

3. Clothes and shoes that feel tight

Fluid retention with swelling is one of the primary symptoms of heart failure, but it can be difficult to recognize, since the swelling can occur in many areas of the body.

What it feels or looks like: Tightness in clothes and shoes, or puffiness of the skin. A relatively sudden increase in girth is a telltale sign of heart failure. Someone with heart failure often looks fatter or bigger around, or you might notice a protruding belly or a shirt with straining buttons that previously fit.

If the feet and ankles swell first, you may notice puffiness over the tops of the shoes or an inability to wear certain shoes that once fit. Roundness or puffiness in the face and neck is also a telltale sign. The increased weight will also show as an increase in pounds on the scale, but this may take longer to occur or to notice than the increase in size.

Why it happens: Reduced blood flow out of the heart causes blood returning to the heart to back up in the veins. The fluid then builds up within tissues, particularly in the abdomen, legs, and feet, a condition known as congestion (not to be confused with nasal congestion). Also, the weakened heart can't pump enough blood to the kidneys, which become less efficient at flushing sodium and fluids from the body.

4. Heart-rhythm problems

It's common for people with heart failure to experience palpitations or changes in heart rhythm.

What it feels like: A fast, irregular, or pounding heartbeat. Someone with heart failure may complain that his heart is racing or that it feels like it's beating too hard. Often, a fast or irregular heartbeat is accompanied by a jittery feeling, similar to that experienced during a panic attack. Other types of arrhythmias often occur as well, including atrial fibrillation and atrial flutter. These problems can be dangerous if left untreated, so it's important to tell the doctor of any heart-rhythm problems.

Why it happens: The heart tries to make up for weakness in pumping by beating faster and harder. As it tires, the heart can't keep up a regular rhythm and skips beats, or beats with varying strength.

5. Loss of appetite

When caring for someone with heart failure, you're likely to hear, "I'm not hungry," even when you know it's time to eat. This lack of appetite may start gradually with your loved one eating smaller portions and feeling full faster, or it may come on suddenly, making you wonder if she has an upset stomach. You may also notice her eating more slowly when she does eat.

What it feels like: A sensation of being full, even when it's been a long time since a meal. You might also notice nausea, constipation, a general feeling of being sick to the stomach, or abdominal pain and tenderness. In addition, the heavy feeling in the chest and abdomen can make it unpleasant to eat. Fatigue can cause someone with heart failure to eat less simply because of fatigue; even chewing can be exhausting.

Why it happens: Fluid buildup around the liver and intestines interferes with digestion. Decreased blood flow to the stomach and intestines slows the entire digestive process, causing problems like constipation and nausea. Also, heart failure causes people to feel full quickly because of fluid retention and swelling.

After having two heart stents 3years ago, my husband has been getting more & more fatigued, he says he is exhausted even before he has done anything, also he has a persistent irritating little cough or wakes up with a sniffle thinking he may be getting a cold but it doesn't come to that but, this past two weeks he has been getting more exhausted, out of breath, irritable& Sharp but now, he has said he is getting a funny warm trickling flushing sensation in right side of chest above his heart. I've noticed now & again a bluish tinge to his lower lip. He is 59yrs old non smoker, home drinker of wine 1/2 bottles per night.

My heart speeds up somewhat often especially after I eat foods even if its something healthy. It usually happens in the evening though also because of this the left side of my body tends to feel slightly numb. Lately my left hand has been shaking as well. I only seem to feel numbness or anything else negative on the left side. No serious pains though. I made poor lifestyle choices so Im not shocked if its something like diabetes ,but im afraid I may need a new heart or something. Regardless im staying positve as possible I actually feel stronger mentally because I understand how mortal I truly am.

Hi, I have many symptoms. By the way I'm 11 months postpartum and since 3months postpartum I have had panic attacks and anxiety attacks. I have had 7 ER trips and my most recent ECG was 3 months ago. I also had 2Decho done last June. All my tests came out negative. Then I recently started a job 2 weeks ago and this week I started doing night shifts. Sometimes I feel like I'm going out of breath and when I lie down I feel like I'm drowning. I also have hot flashes today I have fever. I can't sleep in the morning and when I do and then wake up in the middle of my sleep I can't go back to sleep. My chest seems heavy. I can't schedule a checkup until 3 days from now because of the holidays. I'm really worried.

About 6 weeks ago I started having a full intermittent crampy feeling in my side flank area... That transformed into to weird pinching sensations in my ribs that were very intermittent. I started to developed severe anxiety after googling symptoms. Then came the inability to fall asleep without feeling like I had been holding my breath. I'm a side sleeper so it's not obstruction sleep apnea... The moment RIGHT BEFORE I doze off I would feel this rush come over my body as if my body was jolted with adrenaline. After reading about heart failure, whenever I lay down flat I feel like my breathing becomes more of an effort... But I don't know if it's because I think about it and I get anxious. I have a doctors appt on November 2nd. I hope they are quickly able to diagnose me without misdiagnosing me. I'm scared. I see people commented years ago... I wish I could contact them to see how they are today. Scared and feeling alone. My email is if you could email me so I can ask more questions that would be awesome! I hope it's just anxiety and not some type of organ failure. :(

I have a couple of these symptoms. Except the appetite. My appetite is the same. I should also mention ive gained weight in the past 7 years I use to be a healthy 160pds. Im afraid to weigh myself now. I'm just disgusted in myself for letting myself to get this way. Im guessing my weight at 265 maybe more. I'm 5'9 and I'm a ex alcoholic and a ex smoker. I have back problems also and been diagnosed with degenerate of the lower spine. I take meds for my back. I take them as prescribed. I just got my life back. I'm so scared now. I'm trying to do good. I want to lose weight. I want to live my life without pain or being tired all the time. I don't want to die. I just buried my cousin. She was only 29. She died from heart failure. I'm 39 and im so scared I won't wake up.

I've been feeling several different things. Sometimes I feel like I'm drowning. I may feel overwhemed, heart racing, like my chest is going to explode, suffocating. I'm scared to go see a doctor because of what he might say.

I'm still pretty young, but I've been losing my appetite, been very tired, threw up once (if that's even important), and have the upper/middle part of my chest along with the bottom of my neck feel like it's slowly compressing or being crushed. I'm pretty worried, help would be appreciated. ^^

Almost 22 years old and I'm experiencing almost all of these symptoms. I'm overweight, but recently, I haven't been eating much. Also, whenever I'm alone, I get hot and heavy around the chest. Im usually fine whenever i go out though. Doctors are expensive and am afraid to go.

I recently had to start sleeping with 3 pillows instead of 2. Been skiing this for about 3 weeks now. Before when I was using only 2 pillows I could sleep in either if my sides and even in my back. Since I had to start sleeping with 3 pillows I can only sleep in by right side. If I tried to sleep on my back it my left side and start to fall asleep I would end up waking up because it would be like I couldn't catch my breath. So I would just turn on my right side. I've been having trouble sleeping and always tired during the day. Sometimes I'm even scared to drive because I catch myself dozing off for like a second. Tonight I can't sleep and even when I do start to fall asleep on my RIGHT side tonight I end up waking up trying to catch my breath. Now I'm almost sitting up trying to sleep. I'm scared now because after reading this article I'm scared I might be developing heart failure. What do I need to do to prevent it. Scare and tired Melissa
