Diseases & Conditions-Sudden cardiac arrest

Sudden cardiac arrest is the sudden, unexpected loss of heart function, breathing and consciousness. Sudden cardiac arrest usually results from an electrical disturbance in your heart that disrupts its pumping action, stopping blood flow to the rest of your body.
Sudden cardiac arrest is different from a heart attack, which occurs when blood flow to a portion of the heart is blocked. However, a heart attack can sometimes trigger an electrical disturbance that leads to sudden cardiac arrest.
Sudden cardiac arrest is a medical emergency. If not treated immediately, it causes sudden cardiac death. With fast, appropriate medical care, survival is possible. Administering cardiopulmonary resuscitation (CPR), treating with a defibrillator — or even just compressions to the chest — can improve the chances of survival until emergency personnel arrive.

Heart Diseases & Condition-HEARTBURN

Heartburn

 

Heartburn is a burning pain in your chest, just behind your breastbone. The pain is often worse when lying down or bending over.
Occasional heartburn is common and no cause for alarm. Most people can manage the discomfort of heartburn on their own with lifestyle changes and over-the-counter medications.
Heartburn that is more frequent or interferes with your daily routine may be a symptom of a more serious condition that requires medical care.

Heart Diseases & Conditions-Heart Murmurs

Heart murmurs are sounds during your heartbeat cycle — such as whooshing or swishing — made by turbulent blood in or near your heart. These sounds can be heard with a stethoscope. A normal heartbeat makes two sounds like "lubb-dupp" (sometimes described as "lub-DUP"), which are the sounds of your heart valves closing.

Heart murmurs can be present at birth (congenital) or develop later in life. A heart murmur isn't a disease — but murmurs may indicate an underlying heart problem.

Often, heart murmurs are harmless (innocent) and don't need treatment. Some heart murmurs may require follow-up tests to be sure the murmur isn't caused by a serious underlying heart condition. Treatment, if needed, is directed at the cause of your heart murmur.

Symptoms (Heart Murmurs)

If you have a harmless heart murmur, more commonly known as an innocent heart murmur, you likely won't have any other signs or symptoms.

An abnormal heart murmur may cause no obvious other signs or symptoms, aside from the unusual sound your doctor hears when listening to your heart with a stethoscope. But if you have these signs or symptoms, they may indicate a heart problem:

• Skin that appears blue, especially on your fingertips and lips
• Swelling or sudden weight gain
• Shortness of breath
• Chronic cough
• Enlarged liver
• Enlarged neck veins
• Poor appetite and failure to grow normally (in infants)
• Heavy sweating with minimal or no exertion
• Chest pain
• Dizziness
• Fainting

Causes (Heart Murmurs)

There are two types of heart murmurs: innocent murmurs and abnormal murmurs. A person with an innocent murmur has a normal heart. This type of heart murmur is common in newborns and children.

An abnormal heart murmur is more serious. In children, abnormal murmurs are usually caused by congenital heart disease. In adults, abnormal murmurs are most often due to acquired heart valve problems.

Innocent heart murmurs

An innocent murmur can occur when blood flows more rapidly than normal through the heart. Conditions that may cause rapid blood flow through your heart, resulting in an innocent heart murmur, include:

• Physical activity or exercise
• Pregnancy
• Fever
• Not having enough healthy red blood cells to carry adequate oxygen to your body tissues (anemia)
• An excessive amount of thyroid hormone in your body (hyperthyroidism)
• Phases of rapid growth, such as adolescence

Innocent heart murmurs may disappear over time, or they may last your entire life without ever causing further health problems.

Abnormal heart murmurs

The most common cause of abnormal murmurs in children is when babies are born with structural problems of the heart (congenital heart defects).

Common congenital defects that cause heart murmurs include:

• Holes in the heart or cardiac shunts. Known as septal defects, holes in the heart may or may not be serious, depending on the size of the hole and its location.
  Cardiac shunts occur when there's an abnormal blood flow between the heart chambers or blood vessels, which may lead to a heart murmur.
• Heart valve abnormalities. Congenital heart valve abnormalities are present at birth, but sometimes aren't discovered until much later in life. Examples include valves that don't allow enough blood through them (stenosis) or those that don't close properly and leak (regurgitation), such as mitral valve prolapse.

Other causes of abnormal heart murmurs include infections and conditions that damage the structures of the heart and are more common in older children or adults. For example:

• Valve calcification. This hardening or thickening of valves, as in mitral stenosis or aortic valve stenosis, can occur as you age. Valves may become narrowed (stenotic), making it harder for blood to flow through your heart, resulting in murmurs.
• Endocarditis. This infection of the inner lining of your heart and valves typically occurs when bacteria or other germs from another part of your body, such as your mouth, spread through your bloodstream and lodge in your heart.
  Left untreated, endocarditis can damage or destroy your heart valves. This condition usually occurs in people who already have heart valve abnormalities.
• Rheumatic fever. Although now rare in the United States, rheumatic fever is a serious condition that can occur when you don't receive prompt or complete treatment for a strep throat infection. It can permanently affect the heart valves and interfere with normal blood flow through your heart.

Treatments and drugs (Heart Murmurs)

An innocent heart murmur generally doesn't require treatment because the heart is normal. If innocent murmurs are the result of an illness, such as fever or hyperthyroidism, the murmurs will go away once that condition is treated.

If you or your child has an abnormal heart murmur, treatment may not be necessary. Your doctor may want to monitor the condition over time. If treatment is necessary, it depends on what heart problem is causing the murmur and may include medications or surgery.

Medications

The medication your doctor prescribes depends on the specific heart problem you have. Some medications your doctor might give you include:

• Medications that prevent blood clots (anticoagulants).Your doctor may prescribe anticoagulants, such as aspirin, warfarin (Coumadin, Jantoven) or clopidogrel (Plavix). An anticoagulant prevents blood clots from forming in your heart and causing a heart attack or stroke.
• Water pills (diuretics). Diuretics remove excess fluid from your body, which can help treat other conditions that might worsen a heart murmur, such as high blood pressure.
• Angiotensin-converting enzyme (ACE) inhibitors. ACE inhibitors lower your blood pressure. High blood pressure can worsen underlying conditions that cause heart murmurs.
• Statins. Statins help lower your cholesterol. Having high cholesterol seems to worsen some heart valve problems, including some heart murmurs.
• Beta blockers. These drugs lower your heart rate and blood pressure. They're used for some types of heart valve problems.

Surgery

Many valve conditions can't be treated with medications alone. Depending on your heart condition, your doctor may recommend one of these options to treat a damaged or leaky valve:

Valve repair

To repair a valve, your doctor may recommend one of the following procedures:

• Balloon valvuloplasty. This procedure is performed to relieve a narrowed valve. During a balloon valvuloplasty, a small catheter containing an expandable balloon is threaded into your heart, placed into the valve and then expanded to help widen the narrowed valve.
• Annuloplasty. In this procedure, your surgeon tightens the tissue around the valve by implanting an artificial ring. This allows the leaflets to come together and close the abnormal opening through the valve.
• Repair of structural support. In this procedure, your surgeon replaces or shortens the cords that support the valves (chordae tendineae and papillary muscles) to repair the structural support. When the cords and muscles are the right length, the valve leaflet edges meet and eliminate the leak.
• Valve leaflet repair. In valve leaflet repair, your surgeon surgically separates, cuts or pleats a valve flap (leaflet).

Valve replacement

In many cases, the valve has to be replaced. Options include:

• Open-heart surgery. This is the primary surgical treatment for severe valve stenosis. Your surgeon removes the narrowed valve and replaces it with a mechanical valve or a tissue valve.
  Mechanical valves, made from metal, are durable, but carry the risk of blood clots forming. If you receive a mechanical valve, you'll need to take an anticoagulant medication, such as warfarin (Coumadin, Jantoven), for life to prevent blood clots.
  Tissue valves — which may come from a pig, cow or human deceased donor — often eventually need replacement. Another type of tissue valve replacement that uses your own pulmonary valve (autograft) is sometimes possible.
• Transcatheter aortic valve replacement (TAVR). A less invasive approach, TAVR involves replacing the aortic valve with a prosthetic valve via an artery in your leg or in a small incision in your chest.
  In some cases, a valve can be inserted via a catheter into a tissue replacement valve that needs to be replaced (valve-in-valve procedure).
  TAVR is usually reserved for individuals with severe aortic valve stenosis who are at increased risk of complications from aortic valve surgery.

Doctors used to recommend that most people with abnormal heart murmurs take antibiotics before visiting the dentist or having surgery due to possible complications from a bacterial infection that affects the lining of your heart (infective endocarditis).

Doctors no longer recommend antibiotics before procedures, except for people at highest risk of complications of infective endocarditis, such as those who have an artificial heart valve or people with certain congenital heart defects.

Prevention (Heart Murmurs)

While there's not much you can do to prevent a heart murmur, it is reassuring to know that heart murmurs are not a disease and are often harmless. For children, many murmurs go away on their own as children grow. For adults, murmurs may disappear as the underlying condition causing them improves.

Heart Failure Prevention

The key to preventing heart failure is to reduce your risk factors. You can control or eliminate many of the risk factors for heart disease — high blood pressure and coronary artery disease, for example — by making lifestyle changes along with the help of any needed medications.

Lifestyle changes you can make to help prevent heart failure include:

• Not smoking
• Controlling certain conditions, such as high blood pressure and diabetes
• Staying physically active
• Eating healthy foods
• Maintaining a healthy weight
• Reducing and managing stress

Natural Home Remedy-High Blood Pressure (hypertension)

Ways to control high blood pressure without medication

By making these some lifestyle changes, blood pressure could be reduced and reduce risk of heart disease.

Lifestyle plays an important role in treating high blood pressure. If successfully control your blood pressure with a healthy lifestyle, you might avoid, delay or reduce the need for medication.

Here are some lifestyle changes helps to lower your blood pressure and keep it down.

1. Lose extra pounds and watch your waistline

Blood pressure often increases as weight increases. Being overweight also can cause disrupted breathing while you sleep (sleep apnea), which further raises your blood pressure.

Weight loss is one of the most effective lifestyle changes for controlling blood pressure. Losing just 10 pounds (4.5 kilograms) can help reduce your blood pressure.

Besides shedding pounds, you generally should also keep an eye on your waistline. Carrying too much weight around your waist can put you at greater risk of high blood pressure.

In general:

• Men are at risk if their waist measurement is greater than 40 inches (102 centimeters).
• Women are at risk if their waist measurement is greater than 35 inches (89 centimeters).

These numbers vary among ethnic groups. Ask your doctor about a healthy waist measurement for you.

2. Exercise regularly

Regular physical activity — at least 30 minutes daily — can lower blood pressure by 4 to 9 millimeters of mercury (mm Hg). It's important to be consistent because if stopped exercising, blood pressure can rise again.

If you have slightly high blood pressure (pre-hypertension), exercise can help you avoid developing full-blown hypertension. If you already have hypertension, regular physical activity can bring your blood pressure down to safer levels.

The best types of exercise for lowering blood pressure include walking, jogging, cycling, swimming or dancing. Strength training also can help reduce blood pressure. Talk to your doctor about developing an exercise program.

3. Eat a healthy diet

Eating a diet that is rich in whole grains, fruits, vegetables and low-fat dairy products and skimps on saturated fat and cholesterol can lower your blood pressure by up to 14 mm Hg. This eating plan is known as the Dietary Approaches to Stop Hypertension (DASH) diet.

It isn't easy to change your eating habits, but with these tips, you can adopt a healthy diet:

• Keep a food diary. Writing down what you eat, even for just a week, can shed surprising light on your true eating habits. Monitor what you eat, how much, when and why.
• Consider boosting potassium. Potassium can lessen the effects of sodium on blood pressure. The best source of potassium is food, such as fruits and vegetables, rather than supplements. Talk to your doctor about the potassium level that's best for you.
• Be a smart shopper. Read food labels when you shop and stick to your healthy-eating plan when you're dining out, too.

4. Reduce sodium in your diet

Even a small reduction in the sodium in your diet can reduce blood pressure by 2 to 8 mm Hg.

The effect of sodium intake on blood pressure varies among groups of people. In general, limit sodium to less than 2,300 milligrams (mg) a day or less. However, a lower sodium intake — 1,500 mg a day or less — is appropriate for people with greater salt sensitivity, including:

• African-Americans
• Anyone age 51 or older
• Anyone diagnosed with high blood pressure, diabetes or chronic kidney disease

To decrease sodium in your diet, consider these tips:

• Read food labels. If possible, choose low-sodium alternatives of the foods and beverages you normally buy.
• Eat fewer processed foods. Only a small amount of sodium occurs naturally in foods. Most sodium is added during processing.
• Don't add salt. Just 1 level teaspoon of salt has 2,300 mg of sodium. Use herbs or spices to add flavor to your food.
• Ease into it. If you don't feel you can drastically reduce the sodium in your diet suddenly, cut back gradually. Your palate will adjust over time.

5. Limit the amount of alcohol you drink

Alcohol can be both good and bad for your health. In small amounts, it can potentially lower your blood pressure by 2 to 4 mm Hg.

But that protective effect is lost if you drink too much alcohol — generally more than one drink a day for women and for men older than age 65, or more than two a day for men age 65 and younger. One drink equals 12 ounces of beer, five ounces of wine or 1.5 ounces of 80-proof liquor.

Drinking more than moderate amounts of alcohol can actually raise blood pressure by several points. It can also reduce the effectiveness of blood pressure medications.

6. Quit smoking

Each cigarette you smoke increases your blood pressure for many minutes after you finish. Quitting smoking helps your blood pressure return to normal. People who quit smoking, regardless of age, have substantial increases in life expectancy.

7. Cut back on caffeine

The role caffeine plays in blood pressure is still debated. Caffeine can raise blood pressure by as much as 10 mm Hg in people who rarely consume it, but there is little to no strong effect on blood pressure in habitual coffee drinkers.

Although the effects of chronic caffeine ingestion on blood pressure aren't clear, the possibility of a slight increase in blood pressure exists.

To see if caffeine raises your blood pressure, check your pressure within 30 minutes of drinking a caffeinated beverage. If your blood pressure increases by 5 to 10 mm Hg, you may be sensitive to the blood pressure raising effects of caffeine. Talk to your doctor about the effects of caffeine on your blood pressure.

8. Reduce your stress

Chronic stress is an important contributor to high blood pressure. Occasional stress also can contribute to high blood pressure if you react to stress by eating unhealthy food, drinking alcohol or smoking.

Take some time to think about what causes you to feel stressed, such as work, family, finances or illness. Once you know what's causing your stress, consider how you can eliminate or reduce stress.

If you can't eliminate all of your stressors, you can at least cope with them in a healthier way. Try to:

• Change your expectations. Give yourself time to get things done. Learn to say no and to live within manageable limits. Try to learn to accept things you can't change.
• Think about problems under your control and make a plan to solve them. You could talk to your boss about difficulties at work or to family members about problems at home.
• Know your stress triggers. Avoid whatever triggers you can. For example, spend less time with people who bother you or avoid driving in rush-hour traffic.
• Make time to relax and to do activities you enjoy. Take 15 to 20 minutes a day to sit quietly and breathe deeply. Try to intentionally enjoy what you do rather than hurrying through your "relaxing activities" at a stressful pace.
• Practice gratitude. Expressing gratitude to others can help reduce stressful thoughts.

9. Monitor your blood pressure at home and see your doctor regularly

Home monitoring can help you keep tabs on your blood pressure, make certain your lifestyle changes are working, and alert you and your doctor to potential health complications. Blood pressure monitors are available widely and without a prescription. Talk to your doctor about home monitoring before you get started.

Regular visits with your doctor are also key to controlling your blood pressure. If your blood pressure is under control, you might need to visit your doctor only every six to 12 months, depending on other conditions you might have. If your blood pressure isn't well-controlled, your doctor will likely want to see you more frequently.
