Syndrome of Diabetic

Syndrome of Diabetic

Diabetic hyperosmolar syndrome may take days or even weeks to develop.  Pay attention to possible signs and symptoms, which include:

·         High blood sugar level

·         Excessive thirst

·         Dry mouth

·         Increased urination

·         Warm, dry skin with no sweating

·         Fever

·         Sleepiness

·         Confusion

·         Hallucinations

·         Vision loss

·         Weakness on one side of the body

·         Convulsions

·         Coma

When to see a doctor

Consult your doctor if your blood sugar is persistently higher than the target range your doctor has recommended, or if you experience any signs or symptoms of diabetic hyperosmolar syndrome, such as:

1.    Excessive thirst

2.    Increased urination

3.    Warm, dry skin without sweating

4.    Dry mouth

5.    Fever

Seek emergency care if:

Your blood sugar level is 600 milligrams per decileter (mg/dL), or 33.3 millimoles per liter (mmol/L) or higher

You experience confusion, vision changes or weakness on one side of the body

Causes

Diabetic hyperosmolar syndrome may be triggered by:

·         Illness

·         An underlying infection, such as pneumonia, dental or a urinary tract infection

·         Not following your diabetes treatment plan

·         Certain medications, such as water pills (diuretics)

Sometimes undiagnosed diabetes results in diabetic hyperosmolar syndrome.

Risk factors

Certain factors raise your risk of developing diabetic hyperosmolar syndrome, such as:

Having type 2 diabetes. Although people with type 1 diabetes can be affected, hyperosmolar syndrome is much more common in people with type 2 diabetes.  If you have type 2 diabetes, and you don't monitor your blood sugar or you don't yet know you have type 2 diabetes, you have an even

higher risk.

 Being middle-aged or older. If you're in these age groups, you're more likely to develop diabetic hyperosmolar syndrome.

 Having another chronic health condition. Your risk of hyperosmolar syndrome is increased if you have another chronic illness, such as congestive heart failure or kidney disease.

    Having an infection. Having an illness, such as pneumonia or a virus, causes your blood sugar levels to rise and can increase your risk of diabetic hyperosmolar syndrome.

    Taking certain medications. Some drugs — such as corticosteroids (prednisone), diuretics (hydrochlorothiazide and chlorthalidone) and the anti-seizure medication phenytoin (Dilantin) — can increase your risk of developing hyperosmolar syndrome.

Complications

Diabetic hyperosmolar syndrome can lead to:

    >>> Convulsions

   >>>  Heart attack

    >>> Stroke

    >>> Coma

Without prompt treatment, diabetic hyperosmolar syndrome can be fatal.

Tests and diagnosis

If you experience diabetic hyperosmolar syndrome, prompt diagnosis is critical. The emergency medical team will do a physical exam and may ask those who are with you about your medical history.

Lab tests

You may need various lab tests to measure:

    Your current blood sugar level

    Glycated hemoglobin (A1C) — a blood test that indicates your average blood sugar level for the past two to three months

    Whether or not ketones are present in your urine — ketones are byproducts made when fat is used as fuel instead of glucose

    Your kidney function, by testing the amount of blood urea nitrogen or creatinine in your blood

    The amount of potassium, phosphate and sodium in your blood

You'll be diagnosed with diabetic hyperosmolar syndrome if your blood sugar level is 600 mg/dL (33.3 mmol/L) or higher.

Treatments and drugs

Emergency treatment can correct diabetic hyperosmolar syndrome within hours. Treatment typically includes:

    >> Intravenous fluids

   >>  Insulin to lower your blood sugar levels

  >>   Possibly, potassium, sodium or phosphate replacement to help your cells function correctly

If you have an infection, or an underlying health condition, such as congestive heart failure or kidney disease, these conditions will be treated as well.

Prevention

Good day-to-day control of your diabetes can help you prevent diabetic hyperosmolar syndrome. Keep these tips in mind:

Know the symptoms of high blood sugar. Be alert for the warning symptoms of high blood sugar, as well as the situations that put you at risk of developing hyperosmolar syndrome, such as illness.

    Follow your meal plan. Consistent snacks and meals can help keep your blood sugar level steady.

    Keep an eye on your blood sugar level. Blood sugar monitoring can tell you whether you're keeping your blood sugar level in your target range — and alert you to dangerous highs, especially if you have an infection. Ask your doctor how often you should test your blood sugar.

    Take your medication as directed. If you have frequent episodes of high blood sugar, let your doctor know. He or she may need to adjust the dosage or timing of your medication.

    Exercise regularly. Regular physical activity can help keep your blood sugar levels from going too high. Talk with your doctor before beginning any exercise plan, but for most people, experts recommend 150 minutes of moderate intensity exercise a week — about 30 minutes a day.

    Educate your loved ones, friends and co-workers. Teach loved ones and other close contacts how to recognize early signs and symptoms of blood sugar extremes — and how to summon emergency help should you pass out.

    Wear a medical ID bracelet or necklace. If you're unconscious, the ID can provide valuable information to your loved ones, co-workers and others — including emergency personnel.

    Stay up to date on your vaccinations. Be sure to get an annual flu shot, and ask your doctor if you need the pneumococcal vaccine, which protects against some forms of pneumonia.

Heart Disease

 Heart Disease

What Are the Signs and Symptoms of Heart Disease?

The signs and symptoms of coronary heart disease (CHD) may differ between women and men. Some women who have CHD have no signs or symptoms. This is called silent CHD.

Silent CHD may not be diagnosed until a woman has signs and symptoms of a heart attack, heart failure, or an arrhythmia (irregular heartbeat).

Other women who have CHD will have signs and symptoms of the disease.

The illustration shows the major signs and symptoms of coronary heart disease.

A common symptom of CHD is angina. Angina is chest pain or discomfort that occurs when your heart muscle doesn't get enough oxygen-rich blood.

In men, angina often feels like pressure or squeezing in the chest. This feeling may extend to the arms. Women can also have these angina symptoms. But women also tend to describe a sharp, burning chest pain. Women are more likely to have pain in the neck, jaw, throat, abdomen, or back.

In men, angina tends to worsen with physical activity and go away with rest. Women are more likely than men to have angina while they're resting or sleeping.

In women who have coronary microvascular disease, angina often occurs during routine daily activities, such as shopping or cooking, rather than while exercising. Mental stress also is more likely to trigger angina pain in women than in men.

The severity of angina varies. The pain may get worse or occur more often as the buildup of plaque continues to narrow the coronary (heart) arteries.

Angina

Angina

What is Angina

 Angina (an-JI-nuh or AN-juh-nuh) is chest pain or discomfort that occurs if an area of your heart muscle doesn't get enough oxygen-rich blood.

Angina may feel like pressure or squeezing in your chest. The pain also can occur in your shoulders, arms, neck, jaw, or back. Angina pain may even feel like indigestion.

Angina isn't a disease; it's a symptom of an underlying heart problem. Angina usually is a symptom of coronary heart disease (CHD).

CHD is the most common type of heart disease in adults. It occurs if a waxy substance called plaque (plak) builds up on the inner walls of your coronary arteries. These arteries carry oxygen-rich blood to your heart.

Plaque Buildup in an Artery 

 

Figure A shows a normal artery with normal blood flow. The inset image shows a cross-section of a normal artery. Figure B shows an artery with plaque buildup. The inset image shows a cross-section of an artery with plaque buildup.

Plaque narrows and stiffens the coronary arteries. This reduces the flow of oxygen-rich blood to the heart muscle, causing chest pain. Plaque buildup also makes it more likely that blood clots will form in your arteries. Blood clots can partially or completely block blood flow, which can cause a heart attack.

Angina also can be a symptom of coronary microvascular disease (MVD). This is heart disease that affects the heart’s smallest coronary arteries. In coronary MVD, plaque doesn't create blockages in the arteries like it does in CHD.

Studies have shown that coronary MVD is more likely to affect women than men. Coronary MVD also is called cardiac syndrome X and nonobstructive CHD.

Types of Angina

The major types of angina are stable, unstable, variant (Prinzmetal's), and microvascular. Knowing how the types differ is important. This is because they have different symptoms and require different treatments.

Stable Angina

Stable angina is the most common type of angina. It occurs when the heart is working harder than usual. Stable angina has a regular pattern. (“Pattern” refers to how often the angina occurs, how severe it is, and what factors trigger it.)

If you have stable angina, you can learn its pattern and predict when the pain will occur. The pain usually goes away a few minutes after you rest or take your angina medicine.

Stable angina isn't a heart attack, but it suggests that a heart attack is more likely to happen in the future.

Unstable Angina

Unstable angina doesn't follow a pattern. It may occur more often and be more severe than stable angina. Unstable angina also can occur with or without physical exertion, and rest or medicine may not relieve the pain.

Unstable angina is very dangerous and requires emergency treatment. This type of angina is a sign that a heart attack may happen soon.

Variant (Prinzmetal's) Angina

Variant angina is rare. A spasm in a coronary artery causes this type of angina. Variant angina usually occurs while you're at rest, and the pain can be severe. It usually happens between midnight and early morning. Medicine can relieve this type of angina.

Microvascular Angina

Microvascular angina can be more severe and last longer than other types of angina. Medicine may not relieve this type of angina.

Overview

Experts believe that nearly 7 million people in the United States suffer from angina. The condition occurs equally among men and women.

Angina can be a sign of CHD, even if initial tests don't point to the disease. However, not all chest pain or discomfort is a sign of CHD.

Other conditions also can cause chest pain, such as:

    Pulmonary embolism (a blockage in a lung artery)

    A lung infection

    Aortic dissection (tearing of a major artery)

    Aortic stenosis (narrowing of the heart’s aortic valve)

    Hypertrophic cardiomyopathy (KAR-de-o-mi-OP-ah-thee; heart muscle disease)

    Pericarditis (inflammation in the tissues that surround the heart)

    A panic attack

All chest pain should be checked by a doctor.

Other Names for Angina

    Acute coronary syndrome

    Angina pectoris

    Chest pain

    Coronary artery spasms

    Microvascular angina

    Prinzmetal's angina

    Stable or common angina

    Unstable angina

    Variant angina

What Causes Angina?

Underlying Causes

Angina usually is a symptom of coronary heart disease (CHD). This means that the underlying causes of angina generally are the same as the underlying causes of CHD.

Research suggests that CHD starts when certain factors damage the inner layers of the coronary arteries. These factors include:

    Smoking

    High amounts of certain fats and cholesterol in the blood

    High blood pressure

    High amounts of sugar in the blood due to insulin resistanceexternal link icon or diabetesexternal link icon

Plaque may begin to build up where the arteries are damaged. When plaque builds up in the arteries, the condition is called atherosclerosis (ath-er-o-skler-O-sis).

Plaque narrows or blocks the arteries, reducing blood flow to the heart muscle. Some plaque is hard and stable and causes the arteries to become narrow and stiff. This can greatly reduce blood flow to the heart and cause angina.

Other plaque is soft and more likely to rupture (break open) and cause blood clots. Blood clots can partially or totally block the coronary arteries and cause angina or a heart attack.

Immediate Causes

Many factors can trigger angina pain, depending on the type of angina you have.

Stable Angina

Physical exertion is the most common trigger of stable angina. Severely narrowed arteries may allow enough blood to reach the heart when the demand for oxygen is low, such as when you're sitting.

However, with physical exertion—like walking up a hill or climbing stairs—the heart works harder and needs more oxygen.

Other triggers of stable angina include:

    Emotional stress

    Exposure to very hot or cold temperatures

    Heavy meals

    Smoking

Unstable Angina

Blood clots that partially or totally block an artery cause unstable angina.

If plaque in an artery ruptures, blood clots may form. This creates a blockage. A clot may grow large enough to completely block the artery and cause a heart attack. For more information, go to the animation in "What Causes a Heart Attack?"

Blood clots may form, partially dissolve, and later form again. Angina can occur each time a clot blocks an artery.

Variant Angina

A spasm in a coronary artery causes variant angina. The spasm causes the walls of the artery to tighten and narrow. Blood flow to the heart slows or stops. Variant angina can occur in people who have CHD and in those who don’t.

The coronary arteries can spasm as a result of:

    Exposure to cold

    Emotional stress

    Medicines that tighten or narrow blood vessels

    Smoking

    Cocaine use

Microvascular Angina

This type of angina may be a symptom of coronary microvascular disease (MVD). Coronary MVD is heart disease that affects the heart’s smallest coronary arteries.

Reduced blood flow in the small coronary arteries may cause microvascular angina. Plaque in the arteries, artery spasms, or damaged or diseased artery walls can reduce blood flow through the small coronary arteries.

Who Is at Risk for Angina?

Angina is a symptom of an underlying heart problem. It’s usually a symptom of coronary heart disease (CHD), but it also can be a symptom of coronary microvascular disease (MVD). So, if you’re at risk for CHD or coronary MVD, you’re also at risk for angina.

The major risk factors for CHD and coronary MVD include:

    Unhealthy cholesterol levels.
    High blood pressure.
    Smoking.
    Insulin resistanceexternal link icon or diabetesexternal link icon.
    Overweight or obesity.
    Metabolic syndrome.
    Lack of physical activity.
    Unhealthy diet.
    Older age. (The risk increases for men after 45 years of age and for women after 55 years of age.)
    Family history of early heart disease.

For more detailed information about CHD and coronary MVD risk factors, visit the Health Topics Coronary Heart Disease, Coronary Heart Disease Risk Factors, and Coronary Microvascular Disease articles.

People sometimes think that because men have more heart attacks than women, men also suffer from angina more often. In fact, overall, angina occurs equally among men and women.

Microvascular angina, however, occurs more often in women. About 70 percent of the cases of microvascular angina occur in women around the time of menopause.

Unstable angina occurs more often in older adults. Variant angina is rare; it accounts for only about 2 out of 100 cases of angina. People who have variant angina often are younger than those who have other forms of angina.

What Are the Signs and Symptoms of Angina?

Pain and discomfort are the main symptoms of angina. Angina often is described as pressure, squeezing, burning, or tightness in the chest. The pain or discomfort usually starts behind the breastbone.

Pain from angina also can occur in the arms, shoulders, neck, jaw, throat, or back. The pain may feel like indigestion. Some people say that angina pain is hard to describe or that they can't tell exactly where the pain is coming from.

Signs and symptoms such as nausea (feeling sick to your stomach), fatigue (tiredness), shortness of breath, sweating, light-headedness, and weakness also may occur.

Women are more likely to feel discomfort in the neck, jaw, throat, abdomen, or back. Shortness of breath is more common in older people and those who have diabetesexternal link icon. Weakness, dizziness, and confusion can mask the signs and symptoms of angina in elderly people.

Symptoms also vary based on the type of angina you have.

Because angina has so many possible symptoms and causes, all chest pain should be checked by a doctor. Chest pain that lasts longer than a few minutes and isn't relieved by rest or angina medicine may be a sign of a heart attack. Call 9–1–1 right away.

Stable Angina

The pain or discomfort:

    Occurs when the heart must work harder, usually during physical exertion

    Doesn't come as a surprise, and episodes of pain tend to be alike

    Usually lasts a short time (5 minutes or less)

    Is relieved by rest or medicine

    May feel like gas or indigestion

    May feel like chest pain that spreads to the arms, back, or other areas

Unstable Angina

The pain or discomfort:

    Often occurs at rest, while sleeping at night, or with little physical exertion

    Comes as a surprise

    Is more severe and lasts longer than stable angina (as long as 30 minutes)

    Usually isn’t relieved by rest or medicine

    May get worse over time

    May mean that a heart attack will happen soon

Variant Angina

The pain or discomfort:

    Usually occurs at rest and during the night or early morning hours

    Tends to be severe

    Is relieved by medicine

Microvascular Angina

The pain or discomfort:

    May be more severe and last longer than other types of angina pain

    May occur with shortness of breath, sleep problems, fatigue, and lack of energy

    Often is first noticed during routine daily activities and times of mental stress

 

How Is Angina Diagnosed?

The most important issues to address when you go to the doctor with chest pain are:

    What's causing the chest pain
    Whether you're having or are about to have a heart attack

Angina is a symptom of an underlying heart problem, usually coronary heart disease (CHD). The type of angina pain you have can be a sign of how severe the CHD is and whether it's likely to cause a heart attack.

If you have chest pain, your doctor will want to find out whether it's angina. He or she also will want to know whether the angina is stable or unstable. If it's unstable, you may need emergency medical treatment to try to prevent a heart attack.

To diagnose chest pain as stable or unstable angina, your doctor will do a physical exam, ask about your symptoms, and ask about your risk factors for and your family history of CHD or other heart diseases.

Your doctor also may ask questions about your symptoms, such as:

    What brings on the pain or discomfort and what relieves it?
    What does the pain or discomfort feel like (for example, heaviness or tightness)?
    How often does the pain occur?
    Where do you feel the pain or discomfort?
    How severe is the pain or discomfort?
    How long does the pain or discomfort last?

Diagnostic Tests and Procedures

If your doctor thinks that you have unstable angina or that your angina is related to a serious heart condition, he or she may recommend one or more tests.
EKG (Electrocardiogram)

An EKG is a simple, painless test that detects and records the heart’s electrical activity. The test shows how fast the heart is beating and its rhythm (steady or irregular). An EKG also records the strength and timing of electrical signals as they pass through the heart.

An EKG can show signs of heart damage due to CHD and signs of a previous or current heart attack. However, some people who have angina have normal EKGs.
Stress Testing

During stress testing, you exercise to make your heart work hard and beat fast while heart tests are done. If you can’t exercise, you may be given medicine to make your heart work hard and beat fast.

When your heart is working hard and beating fast, it needs more blood and oxygen. Plaque-narrowed arteries can't supply enough oxygen-rich blood to meet your heart's needs.

A stress test can show possible signs and symptoms of CHD, such as:

    Abnormal changes in your heart rate or blood pressure
    Shortness of breath or chest pain
    Abnormal changes in your heart rhythm or your heart's electrical activity

As part of some stress tests, pictures are taken of your heart while you exercise and while you rest. These imaging stress tests can show how well blood is flowing in various parts of your heart. They also can show how well your heart pumps blood when it beats.
Chest X Ray

A chest x ray takes pictures of the organs and structures inside your chest, such as your heart, lungs, and blood vessels.

A chest x ray can reveal signs of heart failure. It also can show signs of lung disorders and other causes of symptoms not related to CHD. However, a chest x ray alone is not enough to diagnose angina or CHD.
Coronary Angiography and Cardiac Catheterization

Your doctor may recommend coronary angiography (an-jee-OG-ra-fee) if he or she suspects you have CHD. This test uses dye and special x rays to show the inside of your coronary arteries.

To get the dye into your coronary arteries, your doctor will use a procedure called cardiac catheterization (KATH-e-ter-ih-ZA-shun).

A thin, flexible tube called a catheter is put into a blood vessel in your arm, groin (upper thigh), or neck. The tube is threaded into your coronary arteries, and the dye is released into your bloodstream.

Special x rays are taken while the dye is flowing through your coronary arteries. The dye lets your doctor study the flow of blood through your heart and blood vessels.

Cardiac catheterization usually is done in a hospital. You're awake during the procedure. It usually causes little or no pain, although you may feel some soreness in the blood vessel where your doctor inserts the catheter.
Computed Tomography Angiography

Computed tomography (to-MOG-rah-fee) angiography (CTA) uses dye and special x rays to show blood flow through the coronary arteries. This test is less invasive than coronary angiography with cardiac catheterization.

For CTA, a needle connected to an intravenous (IV) line is put into a vein in your hand or arm. Dye is injected through the IV line during the scan. You may have a warm feeling when this happens. The dye highlights your blood vessels on the CT scan pictures.

Sticky patches called electrodes are put on your chest. The patches are attached to an EKG machine to record your heart's electrical activity during the scan.

The CT scanner is a large machine that has a hollow, circular tube in the middle. You lie on your back on a sliding table. The table slowly slides into the opening of the machine.

Inside the scanner, an x-ray tube moves around your body to take pictures of different parts of your heart. A computer puts the pictures together to make a three-dimensional (3D) picture of the whole heart.
Blood Tests

Blood tests check the levels of certain fats, cholesterol, sugar, and proteins in your blood. Abnormal levels may show that you have risk factors for CHD.

Your doctor may recommend a blood test to check the level of a protein called C-reactive protein (CRP) in your blood. Some studies suggest that high levels of CRP in the blood may increase the risk for CHD and heart attack.

Your doctor also may recommend a blood test to check for low levels of hemoglobin (HEE-muh-glow-bin) in your blood. Hemoglobin is an iron-rich protein in red blood cells. It helps the blood cells carry oxygen from the lungs to all parts of your body. If your hemoglobin level is low, you may have a condition called anemia (uh-NEE-me-uh). 

How Is Angina Treated?

Treatments for angina include lifestyle changes, medicines, medical procedures, cardiac rehabilitation (rehab), and other therapies. The main goals of treatment are to:

    Reduce pain and discomfort and how often it occurs
    Prevent or lower your risk for heart attack and death by treating your underlying heart condition

Lifestyle changes and medicines may be the only treatments needed if your symptoms are mild and aren't getting worse. If lifestyle changes and medicines don't control angina, you may need medical procedures or cardiac rehab.

Unstable angina is an emergency condition that requires treatment in a hospital.
Lifestyle Changes

Making lifestyle changes can help prevent episodes of angina. You can:

    Slow down or take rest breaks if physical exertion triggers angina.
    Avoid large meals and rich foods that leave you feeling stuffed if heavy meals trigger angina.
    Try to avoid situations that make you upset or stressed if emotional stress triggers angina. Learn ways to handle stressexternal link icon that can't be avoided.

You also can make lifestyle changes that help lower your risk for coronary heart disease. One of the most important changes is to quit smoking. Smoking can damage and tighten blood vessels and raise your risk for CHD. Talk with your doctor about programs and products that can help you quit. Also, try to avoid secondhand smoke.

If you have trouble quitting smoking on your own, consider joining a support group. Many hospitals, workplaces, and community groups offer classes to help people quit smoking.

For more information about how to quit smoking, go to the Health Topics Smoking and Your Heart article and the National Heart, Lung, and Blood Institute’s (NHLBI’s) "Your Guide to a Healthy Heart."

Following a healthy diet is another important lifestyle change. A healthy diet can prevent or reduce high blood pressure and high blood cholesterol and help you maintain a healthy weight.

A healthy diet includes a variety of fruits and vegetables (including beans and peas). It also includes whole grains, lean meats, poultry without skin, seafood, and fat-free or low-fat milk and dairy products. A healthy diet also is low in sodium (salt), added sugars, solid fats, and refined grains.

For more information about following a healthy diet, go to the NHLBI’s “Your Guide to Lowering Your Blood Pressure With DASH” and the U.S. Department of Agriculture’s ChooseMyPlate.govexternal link icon Web site. Both resources provide general information about healthy eating.

Other important lifestyle changes include:

    Being physically active. Check with your doctor to find out how much and what kinds of activity are safe for you. For more information, go to the Health Topics Physical Activity and Your Heart article.
    Maintaining a healthy weight. If you’re overweight or obese, work with your doctor to create a reasonable weight-loss plan. Controlling your weight helps you control CHD risk factors.
    Taking all medicines as your doctor prescribes, especially if you have diabetesexternal link icon.

Medicines

Nitrates are the medicines most commonly used to treat angina. They relax and widen blood vessels. This allows more blood to flow to the heart, while reducing the heart’s workload.

Nitroglycerin (NI-tro-GLIS-er-in) is the most commonly used nitrate for angina. Nitroglycerin that dissolves under your tongue or between your cheek and gum is used to relieve angina episodes.

Nitroglycerin pills and skin patches are used to prevent angina episodes. However, pills and skin patches act too slowly to relieve pain during an angina attack.

Other medicines also are used to treat angina, such as beta blockers, calcium channel blockers, ACE inhibitors, oral antiplatelet medicines, or anticoagulants (blood thinners). These medicines can help:

    Lower blood pressure and cholesterol levels
    Slow the heart rate
    Relax blood vessels
    Reduce strain on the heart
    Prevent blood clots from forming

People who have stable angina may be advised to get annual flu shots.
Medical Procedures

If lifestyle changes and medicines don't control angina, you may need a medical procedure to treat the underlying heart disease. Both angioplasty (AN-jee-oh-plas-tee) and coronary artery bypass grafting (CABG) are commonly used to treat heart disease.

Angioplasty opens blocked or narrowed coronary arteries. During angioplasty, a thin tube with a balloon or other device on the end is threaded through a blood vessel to the narrowed or blocked coronary artery.

Once in place, the balloon is inflated to push the plaque outward against the wall of the artery. This widens the artery and restores blood flow.

Angioplasty can improve blood flow to your heart and relieve chest pain. A small mesh tube called a stent usually is placed in the artery to help keep it open after the procedure.

During CABG, healthy arteries or veins taken from other areas in your body are used to bypass (that is, go around) your narrowed coronary arteries. Bypass surgery can improve blood flow to your heart, relieve chest pain, and possibly prevent a heart attack.

You will work with your doctor to decide which treatment is better for you.
Cardiac Rehabilitation

Your doctor may recommend cardiac rehab for angina or after angioplasty, CABG, or a heart attack. Cardiac rehab is a medically supervised program that can help improve the health and well-being of people who have heart problems.

The cardiac rehab team may include doctors, nurses, exercise specialists, physical and occupational therapists, dietitians or nutritionists, and psychologists or other mental health specialists.

Rehab has two parts:

    Exercise training. This part helps you learn how to exercise safely, strengthen your muscles, and improve your stamina. Your exercise plan will be based on your personal abilities, needs, and interests.
    Education, counseling, and training. This part of rehab helps you understand your heart condition and find ways to reduce your risk for future heart problems. The rehab team will help you learn how to adjust to a new lifestyle and deal with your fears about the future.

Enhanced External Counterpulsation Therapy

Enhanced external counterpulsation (EECP) therapy is helpful for some people who have angina. Large cuffs, similar to blood pressure cuffs, are put on your legs. The cuffs are inflated and deflated in sync with your heartbeat.

EECP therapy improves the flow of oxygen-rich blood to your heart muscle and helps relieve angina. You typically get 35 1-hour treatments over 7 weeks.
