Cardiomyopathy

Cardiomyopathy is the name for diseases of the heart muscle. These diseases enlarge your heart muscle or make it thicker and more rigid than normal. In rare cases, scar tissue replaces the muscle tissue.

Some people live long, healthy lives with cardiomyopathy. Some people don't even realize they have it. In others, however, it can make the heart less able to pump blood through the body. This can cause serious complications, including:

Heart attacks, high blood pressure, infections, and other diseases can all cause cardiomyopathy. Some types of cardiomyopathy run in families. In many people, however, the cause is unknown. Treatment might involve medicines, surgery, other medical procedures, and lifestyle changes.

Diabetic Heart Disease

What is diabetes?

Diabetes is a disease in which your blood glucose, or blood sugar, levels are too high. Glucose comes from foods you eat. The cells of your body need glucose for energy. A hormone called insulin helps the glucose get into your cells.

With type 1 diabetes, your body doesn't make insulin. With type 2 diabetes, your body doesn't make or use insulin well. Without enough insulin, glucose builds up in your blood and causes high blood sugar levels.

What is diabetic heart disease?

Diabetic heart disease is a term for heart disease in people who have diabetes. If you have diabetes, you are much more likely to develop heart disease or have a stroke than people who don't have diabetes. And you may start having these problems at a younger age.

Over time, the effects of high blood sugar from diabetes can include damage to the blood vessels and nerves in your heart. This damage increases your chance of developing heart diseases, including:

Who is more likely to develop diabetic heart disease?

Diabetes puts you at serious risk for heart disease. It also makes you more likely to develop other conditions that raise your risk even more, including:

Your risk for heart disease is also higher if you

What are the symptoms of diabetic heart disease?

In the early stages, heart disease usually doesn't have any symptoms. But if your heart disease worsens, you can have symptoms. Your symptoms will depend on the type of heart disease you have. They might include:

It's important to know that people with diabetes may not feel chest pain. That's because diabetes can damage the nerves in your heart. If you have any symptoms that could be heart disease, talk with your health care provider.

How is diabetic heart disease diagnosed?

To find out if you have diabetic heart disease, your provider will:

Depending on your risk level, your provider may send you to a cardiologist (a doctor who specializes in heart diseases) for care. If you do have heart disease, treatment will depend on the type of heart disease you have.

How can I prevent diabetic heart disease?

You may be able to prevent heart disease or keep it from getting worse by working with your provider to:

Arrhythmia

An arrhythmia is a problem with the rate or rhythm of your heartbeat. It means that your heart beats too quickly, too slowly, or with an irregular pattern. When the heart beats faster than normal, it is called tachycardia. When the heart beats too slowly, it is called bradycardia. The most common type of arrhythmia is atrial fibrillation, which causes an irregular and fast heart beat.

Many factors can affect your heart's rhythm, such as having had a heart attack, smoking, congenital heart defects, and stress. Some substances or medicines may also cause arrhythmias.

Symptoms of arrhythmias include:

Your doctor can run tests to find out if you have an arrhythmia. Treatment to restore a normal heart rhythm may include medicines, an implantable cardioverter-defibrillator (ICD) or pacemaker, or sometimes surgery.

Congenital Heart Defects

What are congenital heart defects?

Congenital heart defects (CHDs) are problems with the structure of the heart. "Congenital" means that that the problems are present at birth. These defects happen when a baby's heart doesn't develop normally during pregnancy. Congenital heart defects are the most common type of birth defect.

Congenital heart defects can change the way the heart pumps blood. They may make blood flow too slowly, go the wrong way, or block it completely.

There are many types of congenital heart defects. They can happen in one or more parts of the heart. The most common types are:

Congenital heart defects can range from very mild problems that never need treatment to life-threatening problems at birth. The most serious congenital heart defects are called critical congenital heart disease. Babies with these defects usually need surgery in the first year of life. But the symptoms of milder heart defects may not show up until childhood or adulthood.

What causes congenital heart defects?

Researchers often don't know what causes congenital heart defects. They do know that changes in a baby's genes sometimes cause a heart defect. The changed genes may come from the parents, or the changes may happen during pregnancy.

Who is more likely to have a baby with a congenital heart defect?

Several things may increase the chance that your baby has a congenital heart defect, such as:

What are the symptoms of congenital heart defects?

Congenital heart defects don't cause pain. The signs and symptoms are different, depending on the type and number of defects and how serious they are.

Common signs and symptoms of congenital heart defects include:

What other problems do congenital heart defects cause?

Congenital heart defects don't always cause other problems. If they do, which problems you have would depend on the type and number of defects and how serious the defects are.

Children with congenital heart defects are more likely to:

People with congenital heart defects may develop other health conditions, including:

How are congenital heart defects diagnosed?What are the treatments for congenital heart defects?

Treatment depends on the type of congenital heart defect and how serious it is. Possible treatments include:

All children and adults who have congenital heart defects need regular follow-up care from a cardiologist (a doctor who specializes in heart diseases) throughout their life, even if their defect was repaired.

Some people may need several heart surgeries or catheterizations over the years. They may also need to take medicines to help their hearts work as well as possible.

Health Problems in Pregnancy

Every pregnancy has some risk of problems, but there are certain conditions and health issues that can raise that risk, such as:

Any of these can affect your health, the health of your baby, or both.

If you have a chronic condition, you should talk to your health care provider about how to minimize your risk before you get pregnant. Once you are pregnant, you may need a health care team to monitor your pregnancy. Some common conditions that can complicate a pregnancy include:

Other conditions that may make pregnancy risky can develop during pregnancy - for example, gestational diabetes and Rh incompatibility. Good prenatal care can help detect and treat them.

Some symptoms, such as nausea, back pain, and fatigue, are common during pregnancy. Sometimes it is hard to know what is normal. Call your health care provider if something is bothering or worrying you.

Heart Diseases

What is heart disease?

Heart disease is a general term that includes many types of heart problems. It's also called cardiovascular disease, which means heart and blood vessel disease.

Heart disease is the leading cause of death in the United States, but there are ways to prevent and manage many types of heart disease.

What are the types of heart disease?

There are many different types of heart disease. Some you may be born with, called congenital heart disease. Other types develop during your lifetime.

Coronary artery disease (also called coronary heart disease) is the most common type of heart disease. It happens slowly over time when a sticky substance called plaque builds up in the arteries that supply your heart muscle with blood. The plaque narrows or blocks blood flow to the heart muscle and can lead to other heart problems:

Other types of heart diseases may affect your heart valves or heart muscle (cardiomyopathy).

What causes heart diseases?

The causes of heart disease depend on the type of disease. Some possible causes include lifestyle, genetics, infections, medicines, and other diseases.

Who is more likely to develop heart diseases?

There are many different factors that can make you more likely to develop heart disease. Some of these factors you can change, but others you cannot.

What are the symptoms of heart disease?

Your symptoms will depend on the type of heart disease you have. You may not have symptoms at first. In some cases, you may not know you have heart disease until you have a complication such as a heart attack.

How are heart diseases diagnosed?

To find out if you have heart disease, your health care provider will:

In some cases, your provider may refer you to a cardiologist (a doctor who specializes in heart diseases) for tests, diagnosis, and care.

What are the treatments for heart disease?

Treatment plans for heart disease depend on the type of heart disease you have, how serious your symptoms are, and what other health conditions you have. Possible treatments may include:

Can heart diseases be prevented?

You may be able to lower your risk of certain heart diseases by making heart-healthy lifestyle changes and managing any other medical conditions you have.

Heart Failure

What is heart failure?

Heart failure means that your heart can't pump enough oxygen-rich blood to meet your body's needs. Heart failure doesn't mean that your heart has stopped or is about to stop beating. But without enough blood flow, your organs may not work well, which can cause serious problems.

Heart failure can affect one or both sides of your heart:

Left-sided heart failure is more common than right-sided heart failure.

What causes heart failure?

Heart failure can start suddenly after a medical condition or injury damages your heart muscle. But in most cases, heart failure develops slowly from long-term medical conditions.

Conditions that can cause heart failure include:

Over time, left-sided heart failure can lead to right-sided heart failure.

Who is more likely to develop heart failure?

Heart failure can happen at any age. It happens to both men and women, but men often develop it at a younger age than women. Your chance of developing heart failure increases if:

What are the symptoms of heart failure?

The symptoms of heart failure depend on which side of your heart is affected and how serious your condition has become. Most symptoms are caused by reduced blood flow to your organs and fluid buildup in your body.

Fluid buildup happens because the flow of blood through your heart is too slow. As a result, blood backs up in the vessels that return the blood to your heart. Fluid may leak from the blood vessels and collect in the tissues of your body, causing swelling (edema) and other problems.

Symptoms of heart failure may include:

At first you may have no symptoms or mild symptoms. As the disease gets worse, your symptoms will usually bother you more.

What other problems does heart failure cause?

Fluid buildup and reduced blood flow to your organs can lead to serious problems, including:

How is heart failure diagnosed?

To find out if you have heart failure, your doctor will:

In some cases, your doctor may refer you to a cardiologist (a doctor who specializes in heart diseases) for tests, diagnosis, and care.

What are the treatments for heart failure?

Your treatment will depend on the type of heart failure you have and how serious it is. There's no cure for heart failure. But treatment can help you live longer with fewer symptoms.

Even with treatment, heart failure usually gets worse over time, so you'll likely need treatment for the rest of your life.

Most treatment plans include:

You may need heart surgery if:

As part of your treatment, you'll need to pay close attention to your symptoms, because heart failure can worsen suddenly. Your provider may suggest a cardiac rehabilitation program to help you learn how to manage your condition.

Can heart failure be prevented?

You may be able to prevent or delay heart failure if you:

Muscle Disorders

Your muscles help you move and help your body work. Different types of muscles have different jobs. There are many problems that can affect muscles. Muscle disorders can cause weakness, pain or even paralysis.

Causes of muscle disorders include:

Sometimes the cause of muscle disorders is unknown.

Newborn Screening

Your newborn infant has screening tests before leaving the hospital. There may be different tests depending on the state where you live. They include:

These tests look for serious medical conditions. If not treated, some of these conditions can cause lifelong health problems. Others can cause early death. With early diagnosis, treatment can begin right away, before serious problems can occur or become permanent.

If a screening shows that your baby might have a condition, the health care provider or the state health department will call you. It is important to follow up quickly. Further testing can verify whether your baby has the condition. If so, treatment should start right away.
