The heart is a large muscle that pumps blood throughout the body. Blood carries oxygen to all the organs including the brain, plus the muscles and skin. After the body takes the oxygen out of the blood, the blood returns to the heart. The right side of the heart collects that blood. It pumps the blood to the lungs to get fresh oxygen. This oxygen-rich blood from the lungs then returns to the left side of the heart. There it's pumped back out to the brain and rest of the body, starting the process all over.
Heart failure occurs when the heart muscle does not function normally. This causes your body to retain fluids and reduces blood flow. This can be caused by heart muscle weakness or stiffness, or a heart valve problem.
When the left side of the heart is failing, it can’t handle the blood it's getting from the lungs. Pressure then builds up in the veins of the lungs, causing fluid to leak into the lung tissues. This may be referred to as congestive heart failure. This causes you to feel short of breath, weak, or dizzy. These symptoms are often worse with physical activity, such as climbing stairs or walking up hills. Lying flat is uncomfortable and can make your breathing worse. This may make sleeping difficult. You may need to use extra pillows to raise your upper body to help you sleep well. You may also feel weak or tired and have less energy during activities.
Causes of heart failure include:
Coronary artery disease
Heart attack (myocardial infarction or AMI) in the past
High blood pressure
Damaged heart valve
Illegal drug use, such as methamphetamine
Inflammatory conditions including infection
Heart failure is usually a long-term (chronic) condition. The purpose of medical treatment is to improve the pumping action of the heart, and remove extra water and fluids from the body. A number of medicines can help with this, improve symptoms, and keep the heart from becoming weaker. Cardiac procedures and surgery may help certain conditions that cause heart failure. In some cases of severe heart failure, a mechanical device can be placed in the heart to help the heart pump. A heart transplant is another choice. Another major goal is to better treat the causes of heart failure, such as diabetes, high blood pressure, and your lifestyle.
Check your weight every day. A sudden increase in weight gain could mean heart failure is getting worse.
Use the same scale every day.
Weigh yourself at the same time every day. Wearing similar clothing or no clothes at all.
Make sure the scale is on the floor, not on a rug.
Keep a record of your weight every day, so your healthcare provider can see it. If you are not given a log sheet for this, keep a separate journal for this purpose.
Cut back on how much salt (sodium) you eat:
Your provider will tell you how much salt to have daily. This is usually 1.500 mg or less.
Limit high-salt foods. These include olives, pickles, smoked meats, processed foods, and salted potato chips.
Don't add salt to your food at the table. Use only small amounts of salt when cooking.
Don't binge on salt-heavy meals.
Follow your healthcare provider's advice about how much fluid you should have.
Stop taking illegal drugs.
Cut back on the amount of alcohol you drink.
Lose weight if you are overweight. The extra weight puts a lot of stress on the heart.
Stay active. Talk with your provider about an exercise program that is safe for your heart.
Keep your feet elevated to reduce swelling. Ask your provider about support hose to help prevent daytime leg swelling.
Follow your healthcare provider's instructions closely.
Besides taking your medicine as instructed, another important part of treatment includes lifestyle changes. These include diet, physical activity, stopping smoking, and weight control.
Improve your diet. Often in the hospital, people are given a heart healthy diet. This includes more fresh foods, lower saturated fat, less processed foods, and lower salt.
Follow up with your healthcare provider, or as advised. Make sure to keep any appointments that were made for you. This can help better control heart failure.
If an X-ray was done, you will be told of any new findings that may affect your care.
Become severely short of breath
Feel lightheaded, or feel like you might pass out or faint
Have chest pain or discomfort that is different than usual, the medicines your provider told you to use for this don't help, or the pain lasts longer than 10 to 15 minutes
Develop a rapid heart rate suddenly
Call your healthcare provider right away if you have any of these signs of worsening heart failure:
Sudden weight gain. This means more than
Trouble breathing not related to being active
New or increased swelling of your legs or ankles
Swelling or pain in your abdomen
Breathing trouble at night, waking up short of breath, or needing more pillows to elevate your upper body to help you breathe
Frequent coughing that doesn’t go away
Feeling much more tired than usual
