pericarditis

The pericardium is a membrane, or sac, that surrounds your heart. It holds the heart in place and helps it work properly. Problems with the pericardium include:

• Pericarditis - an inflammation of the sac. It can be from a virus or other infection, a heart attack, heart surgery, other medical conditions, injuries, and certain medicines.
• Pericardial effusion - the buildup of fluid in the sac
• Cardiac tamponade - a serious problem in which buildup of fluid in the sac causes problems with the function of the heart

Symptoms of pericardial problems include chest pain, rapid heartbeat, and difficulty breathing. Fever is a common symptom of acute pericarditis. Your doctor may use a physical exam, imaging tests, and heart tests to make a diagnosis. Treatment depends on the cause.

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 failure
• Abnormal heart rhythms
• Heart valve problems
• Sudden cardiac arrest (SCA)

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.

COVID-19 (coronavirus disease 2019) is an illness caused by a virus. This virus is a coronavirus called SARS-CoV-2. In the United States, there are several vaccines that are effective at protecting people from getting seriously ill, being hospitalized, and dying from COVID-19. These vaccines are being used under Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration (FDA). This means that the vaccines have met the FDA's scientific standards for safety, effectiveness, and manufacturing quality that are needed to support authorization.

This page includes details about the vaccines and the vaccination program, including where you can find a vaccine.

Each year almost 800,000 Americans have a heart attack. A heart attack happens when blood flow to the heart suddenly becomes blocked. Without the blood coming in, the heart can't get oxygen. If not treated quickly, the heart muscle begins to die. But if you do get quick treatment, you may be able to prevent or limit damage to the heart muscle. That's why it's important to know the symptoms of a heart attack and call 911 if you or someone else is having them. You should call, even if you are not sure that it is a heart attack.

The most common symptoms in men and women are:

• Chest discomfort. It is often in center or left side of the chest. It usually lasts more than a few minutes. It may go away and come back. It can feel like pressure, squeezing, fullness, or pain. It also can feel like heartburn or indigestion.
• Shortness of breath. Sometimes this is your only symptom. You may get it before or during the chest discomfort. It can happen when you are resting or doing a little bit of physical activity.
• Discomfort in the upper body. You may feel pain or discomfort in one or both arms, the back, shoulders, neck, jaw, or upper part of the stomach.

You may also have other symptoms, such as nausea, vomiting, dizziness, and lightheadedness. You may break out in a cold sweat. Sometimes women will have different symptoms then men. For example, they are more likely to feel tired for no reason.

The most common cause of heart attacks is coronary artery disease (CAD). With CAD, there is a buildup of cholesterol and other material, called plaque, on their inner walls or the arteries. This is atherosclerosis. It can build up for years. Eventually an area of plaque can rupture (break open). A blood clot can form around the plaque and block the artery.

A less common cause of heart attack is a severe spasm (tightening) of a coronary artery. The spasm cuts off blood flow through the artery.

At the hospital, health care providers make a diagnosis based on your symptoms, blood tests, and different heart health tests. Treatments may include medicines and medical procedures such as coronary angioplasty. After a heart attack, cardiac rehabilitation and lifestyle changes can help you recover.

Heart diseases are the number one killer in the United States. They are also a major cause of disability. If you do have heart disease, it is important to find it early, when it is easier to treat. Blood tests and heart health tests can help find heart diseases or identify problems that can lead to heart diseases. There are several different types of heart health tests. Your health care provider will decide which test or tests you need, based on your symptoms (if any), risk factors, and medical history.

Cardiac catheterization is a medical procedure used to diagnose and treat some heart conditions. For the procedure, your provider puts a catheter (a long, thin, flexible tube) into a blood vessel in your arm, groin, or neck, and threads it to your heart. The provider can use the catheter to:

• Do a coronary angiography. This involves putting a special type of dye in the catheter, so the dye can flow through your bloodstream to your heart. Then your provider takes x-rays of your heart. The dye allows your provider to see your coronary arteries on the x-ray, and to check for coronary artery disease (CAD). CAD is caused by plaque buildup in the arteries.
• Take samples of your blood and heart muscle.
• Examine your heart valves.
• Do procedures such as angioplasty or minor heart surgeries to repair congenital heart defects or replace heart valves.

A cardiac CT (computed tomography) scan is a painless imaging test that uses x-rays to take detailed pictures of your heart and its blood vessels. Computers can combine these pictures to create a three-dimensional (3D) model of your whole heart. This test can help providers detect or evaluate various heart problems, including:

• Coronary artery disease
• Calcium buildup in the coronary arteries
• Congenital heart defects
• Problems with the aorta (the main artery that carries blood away from the heart)
• Problems with heart function and valves
• Pericardial diseases

Before you have the test, you get an injection of contrast dye. The dye highlights your heart and blood vessels in the pictures. The CT scanner is a large, tunnel-like machine. You lie still on a table that slides you into the scanner, and the scanner takes the pictures.

Cardiac MRI (magnetic resonance imaging) is a painless imaging test that uses radio waves, magnets, and a computer to create detailed pictures of your heart. It can help your provider figure out whether you have heart disease, and if so, how severe it is. A cardiac MRI can also help your provider decide the best way to treat heart problems such as:

• Congenital heart defects
• Coronary artery disease
• Heart valve problems
• Pericarditis
• Cardiac tumors
• Damage from a heart attack

The MRI is a large, tunnel-like machine. You lie still on a table that slides you into the MRI machine. The machine makes loud noises as it takes pictures of your heart. Sometimes before the test, you might get an injection of contrast dye. The dye highlights your heart and blood vessels in the pictures.

A chest x-ray creates pictures of the organs and structures inside your chest, such as your heart, lungs, and blood vessels. It can reveal signs of heart failure, as well as lung disorders and other causes of symptoms not related to heart disease.

Coronary angiography (angiogram) is a procedure that uses contrast dye and x-ray pictures to look at the insides of your arteries. It can show whether plaque is blocking your arteries and how severe the blockage is. Providers use this procedure to diagnose heart diseases after chest pain, sudden cardiac arrest (SCA), or abnormal results from other heart tests such as an EKG or a stress test.

You usually have a cardiac catheterization to inject the dye into your coronary arteries. Then the provider will take special x-rays while the dye is flowing through your coronary arteries. The dye lets your provider study the flow of blood through your heart and blood vessels.

Echocardiography, or echo, is a painless test that uses sound waves to create moving pictures of your heart. The pictures show the size and shape of your heart. They also show how well your heart's chambers and valves are working. Providers use an echo to diagnose many different heart problems, and to check how severe they are.

There are several different types of echocardiography. For transthoracic echocardiography (the most common type), a technician applies gel to your chest. The gel helps sound waves reach your heart. The technician moves a transducer (wand-like device) across your chest. The transducer connects to a computer. It transmits ultrasound waves into your chest, and the waves bounce (echo) back. The computer converts the echoes into pictures of your heart.

An electrocardiogram, also called an ECG or EKG, is a painless test that detects and records your heart's electrical activity. It shows how fast your heart is beating and whether its rhythm is steady or irregular.

An EKG may be part of a routine exam to screen for heart disease. Or you may get it to detect and study heart problems such as heart attacks, arrhythmia, and heart failure.

For the test, you lie still on a table and a nurse or technician attaches electrodes (patches that have sensors) to the skin on your chest, arms, and legs. Wires connect the electrodes to a machine that records your heart's electrical activity.

Stress testing looks at how your heart works during physical stress. It can help to diagnose coronary artery disease, and to check how severe it is. It can also check for other problems, including heart valve disease and heart failure.

For the test, you exercise (or are given medicine if you are unable to exercise) to make your heart work hard and beat fast. While this is happening, you get an EKG and blood pressure monitoring. Before or after the test, you might also have an echocardiogram, or other imaging tests such as a nuclear scan. For the nuclear scan, you get an injection of a tracer (a radioactive substance), which travels to your heart. Special cameras detect the energy from the tracer to craeate pictures of your heart. You have pictures taken after you exercise, and then after you rest.

Lupus is a chronic (long-lasting) type of autoimmune disease.Autoimmune diseases happen when your immune system attacks healthy cells and tissues by mistake. This attack causes inflammation. It can also damage many parts of the body, including the joints, skin, kidneys, heart, lungs, and brain.

There are several types of lupus:

• Systemic lupus erythematosus (SLE) is the most common type. It can be mild or severe and can affect many parts of the body.
• Cutaneous lupus affects the skin. It causes a rash or sores, usually after your skin is exposed to sunlight. The two major types of cutaneous lupus are discoid lupus and subacute cutaneous lupus.
• Drug-induced lupus is caused by a reaction to some medicines. The symptoms may start 3 to 6 months after starting the medicine. The symptoms usually go away when you stop taking the medicine.
• Neonatal lupus, which is rare, affects newborns. It is caused by certain antibodies that are passed from the pregnant parent to the baby.

The cause of lupus is unknown. Researchers are studying what might cause or trigger the disease, such as:

• Genetics
• Environmental factors, such as viral infections, sunlight, certain medicines, and smoking
• Problems with the immune system

Anyone can get lupus, but women get it much more often than men.

Lupus is more common in African Americans than in White people. It is also more common in people of American Indian and Asian descent. African American and Hispanic women are more likely to have severe forms of lupus.

Lupus can have many symptoms, and they differ from person to person. Some of the more common ones are:

• Arthritis, causing painful and swollen joints and morning stiffness
• Fever
• Fatigue or feeling tired often
• Red rashes, most often on the face (also called the "butterfly rash")
• Chest pain when taking a deep breath
• Hair loss
• Pale or purple fingers or toes, from cold and stress (Raynaud phenomenon)
• Sensitivity to the sun
• Swelling in legs or around eyes
• Mouth ulcers
• Swollen glands
• Headache and dizziness
• Confusion and memory problems

Symptoms may come and go. When you are having symptoms, it is called a flare. Flares can range from mild to severe. New symptoms may appear at any time.

Lupus causes inflammation throughout your body. This can cause problems in your organs, including:

• Kidney damage (lupus nephritis).
• Heart problems, including inflammation in the heart (myocarditis), heart valves, or lining of the heart muscle (pericarditis).
• Inflammation of blood vessels (vasculitis).
• Blood clots
• Inflammation of the tissue that surrounds the lungs (pleurisy). This can make it painful to breathe.

Some people with lupus may be more likely to develop other conditions, such as coronary artery disease (CAD) and atherosclerosis.

There is no specific test for lupus, and it's often mistaken for other diseases that cause similar symptoms. So it may take a while to get a diagnosis. To find out if you have lupus, your health care provider:

• Will ask about your symptoms, medical history, and family health history
• Will do a complete physical exam
• May order blood tests, such as ANA (antinuclear antibody), antibodies, complete blood count, and complement tests
• May order other tests, such as urine tests
• May do biopsies:
  • Skin biopsy (looking at skin samples under a microscope)
  • Kidney biopsy (looking at tissue from your kidney under a microscope)

There is no cure for lupus, but medicines and lifestyle changes can help control it.

People with lupus often need to see different providers. You will most likely have a primary care provider and a rheumatologist (a doctor who specializes in diseases of the joints and muscles). Which other specialists you will depend on how lupus affects your body. For example, if lupus is damaging your heart or blood vessels, you would see a cardiologist (a doctor who specializes in heart diseases).

Your primary care provider should coordinate care between all of your other providers and treat other problems as they come up. You and your primary care provider will develop a treatment plan to fit your needs. You will both review the plan often to make sure that it is working. You should report new symptoms to your provider right away so that your treatment plan can be changed, if needed.

The goals of a treatment plan are to:

• Prevent flares
• Treat flares when they occur
• Reduce organ damage and other problems
• Improve your quality of life

Treatments may include drugs to:

• Reduce fever, swelling, and pain
• Reduce inflammation in your body
• Prevent or reduce flares
• Reduce or prevent damage to joints
• Suppress (lower) the activity of your immune system

Besides taking medicines for lupus, you may need to take medicines for problems that are related to lupus such as high cholesterol, high blood pressure, or infection.

Alternative and complementary therapies are therapies that are not part of standard treatments. Some people try alternative and complementary therapies to improve their lupus symptoms. But research has not clearly shown whether these treatments may help or treat lupus. Talk to your provider before trying any new treatments.

It is important to take an active role in your treatment. It helps to learn more about lupus - being able to spot the warning signs of a flare can help you prevent the flare or make the symptoms less severe.

It is also important to find ways to cope with the stress of having lupus. Exercising and finding ways to relax may make it easier for you to cope. A good support system can also help.
