Herbal Medicine

By. holistic-online.com

Green Tea - Popular in Asia for centuries, green tea helps to keep blood pressure under control. It also may help keep cholesterol from clogging arteries. The tea contains Epigallocatechin Gallate (EGCG) and other substances that protect the body against the dangers of oxidation, while helping to keep the harmful LDL cholesterol down and the helpful HDL cholesterol up. They also assist in keeping blood pressure under control.

Garlic - prevent the oxidation of LDL cholesterol, may prevent the liver from producing excess fat and cholesterol.

In one study, adding as little as two ounces of garlic juice to a fatty, cholesterol-laden meal was found to actually lower the cholesterol by up to 7 percent. Another study found that 600 mg of garlic powder a day could push the total cholesterol down by some 10 percent. Other research has corroborated these findings reporting that garlic can lower both total and LDL cholesterol while raising the HDL ("good") cholesterol.

A 10-month study found that eating three cloves of garlic a day keeps the cholesterol down for extended periods. And because it contains ajoene and other substances, garlic also helps to keep the blood "thin" and free of potentially deadly blood clots

Hawthorn (Crataegus) contains a combination of flavonoids that can protect the heart against oxygen deprivation and the development of abnormal rhythms. It dilates coronary blood vessels, improving the flow of blood to the heart. It strengthens the heart muscle and works to help the body rid itself of excess salt and water. It reduces blood levels of cholesterol and triglycerides, and brings down high blood pressure. Choose a standardized extract containing 1.8 percent vitexin-2 rhamnosides.

Arjuna - Arjuna, an important Ayurvedic herb, is a coronary vasodilator. It protects the heart, strengthens circulation, and helps to maintain the tone and health of the heart muscle. It is also useful in stopping bleeding and to promote healing after a heart attack.

Ginger - Ginger is an important herb for a healthy heart. Ayurvedic physicians suggest that eating a little bit of ginger every day will help to prevent heart attack. It reduces cholesterol. It also reduces blood pressure and prevents blood clots.

Ginger's heart-helping attributes are similar to that of garlic. Ginger interferes with the long sequence of events necessary for blood clots to form. This helps to prevent clots that can lodge in narrowed coronary arteries and set off a heart attack.

Turmeric lowers blood cholesterol levels by stimulating the production of bile. It also prevents the formation of dangerous blood clots that can lead to heart attack.

• Onions: Onions contain adenosine and other "blood thinners" that help to prevent the formation of blood clots. In addition to thinning the blood, onions can help keep the coronary arteries open and clear by increasing the HDL. Eating half a raw onion every day can increase HDL by 20 to 30 percent.

Ginkgo biloba improves the flow of blood throughout the body. It is also an antioxidant. Ginkgo biloba can benefit the cardiovascular system by preventing the formation of free radicals. Take a ginkgo extract containing 24-percent ginkgo flavone glycosides.

Fo-ti (ho shou wu, Polygonum multiflorum), combats the symptoms of heart disease, helping to reduce blood pressure and blood-cholesterol levels.

Alfalfa: Alfalfa leaves and sprouts help reduce the blood cholesterol levels and plaque deposits on artery walls.

Citrin - an extract from the plant Garcinia cambogia, inhibits the synthesis of fatty acids in the liver. It helps to prevent the accumulation of potentially dangerous fats in the body.

Guggul - This ayurvedic herb is derived from a type of myrrh tree. It has been shown to lower blood-fat levels while raising levels of HDL, the so called "good cholesterol."
Note: Do not use this herb if you have a thyroid disorder.

Grape seed extract with oligomeric proanthocyanidins (OPCS) may lower high blood pressure, which can cause heart disease.

Soy: Soy had been long popular in Asia. It has been proven to be heart protectors also.

When people with high cholesterol are put on a low-fat, low-cholesterol diet, their cholesterol levels usually drop. But if you replace the animal protein in their diet with soy protein, their cholesterol levels are found to drop significantly lower. One study has showed that soy protein could cancel out the effect of 500 mg of cholesterol deliberately added to the daily diet.

Although soy can lower cholesterol levels in those with normal levels, it works best in people with elevated cholesterol.

Brewer's Yeast: Brewer's yeast can lower the total cholesterol and LDL while raising the helpful HDL. (Brewer's yeast is not the same as the yeast we use in the kitchen.) In one study with normal- and high-cholesterol patients, 11 healthy volunteers were given brewer's yeast. Eight weeks later, 10 of the 11 people with normal cholesterol levels had even lower total cholesterol levels and increased HDL levels. Among the 15 volunteers with high cholesterol, eight enjoyed the same beneficial results.

Cordyceps - Cordyceps is a Chinese herb. It can slow the heart rate, increase blood supply to the arteries and heart, and lower blood pressure.

Artichoke leaf extract reduces blood cholesterol and protects the liver. This herb has antioxidant activity and may inhibit the oxidation of cholesterol, a factor in atherosclerosis.

Cat's claw contains a variety of valuable phytochemicals that inhibit the processes involved in the formation of blood clots. It increases circulation and inhibits inappropriate clotting. Thus, it may help to prevent stroke and reduce the risk of heart attack.

Oat straw and kava kava are tonics for the nervous system.

White willow bark contains salicin, an aspirinlike compound. It has been used for centuries much as aspirin is today. Aspirin is often recommended for cardiovascular condition. This herb may provide the same protection without stomach upsets associated with aspirin.
Note: Do not take this herb if you are allergic to aspirin.

• Other herbs that are beneficial for cardiovascular disorders include barberry, black cohosh, butcher's broom, cayenne (capsicum), dandelion, ginseng, and valerian root.

The following herbs are heart friendly:

alfalfa, astragalus, garlic, ginger, ginkgo, ginseng, hawthorn berry, kelp, kola, motherwort, myrrh, psyllium (Metamucil), passion flower, red pepper, saffron, Siberian ginseng, skullcap, tarragon, turmeric, and valerian

Caution: Do not use barberry or black cohosh during pregnancy. Do not use ginseng if you have high blood pressure. Also avoid the herbs ephedra (ma huang) and licorice, as they cause a rise in blood pressure.

Heart Attack Supplements

Heart Attack Facts
by. healthfusion.wordpress.com

•1.5 million heart attacks occur in the United States each year with 500,000 deaths.
•More than 233,000 women die annually from cardiovascular disease.
•A heart attack occurs about every 20 seconds with a heart attack death about every minute.
•Sudden death is more common among women with heart attack.
•Almost 14 million Americans have a history of heart attack or angina.
•Costs related to heart attack exceed 60 billion dollars per year.

Omega 3 EPA

When research showed that Greenland Eskimos and the Japanese enjoy remarkable cardiovascular health, scientists began delving for the reason. They discovered that these cultures consume foods rich in omega-3 fatty acids. Today, the benefits of these important compounds are widely known and recognized.

Identified as essential elements for good health, omega-3 fatty acids are not made naturally by the body, so they must be consumed through the diet. Primarily available in cold-water fish, including salmon, tuna, mackerel, and halibut, omega-3 fatty acids are also found in tofu, soybean, nuts, and canola oils. Most people fall short of consuming the necessary amounts of these critical nutrients, so supplementation is needed.

Many medical professionals recommend omega-3 fatty acid dietary supplements for the general population. As we hear all too often in the news, cold-water fish are frequently contaminated with toxins, but most fish-oil-based supplements tend to be free of these toxins.

To prevent a heart attack:

By. www.nlm.nih.gov

- Keep your blood pressure, blood sugar, and cholesterol under control.
- Don't smoke.
- Consider drinking 1 to 2 glasses of alcohol or wine each day. Moderate amounts of alcohol may reduce your risk of cardiovascular problems. However, drinking larger amounts does more harm than good.
- Eat a low fat diet rich in fruits and vegetables and low in animal fat. Eat fish twice a week.
- Baked or grilled fish is better than fried fish. Frying can destroy some of the benefits.
- Exercise daily or several times a week. Walking is a good form of exercise. Talk to your doctor before starting an exercise routine.
- Lose weight if you are overweight.

If you have one or more risk factors for heart disease, talk to your doctor about possibly taking aspirin to help prevent a heart attack. Aspirin therapy (dose 75 mg to 325 mg a day) or a drug called clopidogrel may be prescribed for women at high risk for heart disease. Aspirin therapy is recommended for women over age 65 to prevent heart attack and stroke as long as blood pressure is controlled and the benefit is likely to outweigh the risk of gastrointestinal side effects. Regular use of aspirin is not recommended for healthy women under age 65 to prevent heart attacks.

New guidelines no longer recommend hormone replacement therapy, vitamins E or C, antioxidants, or folic acid to prevent heart disease.

After a heart attack, you will need regular follow-up care to reduce the risk of having a second heart attack. Often, a cardiac rehabilitation program is recommended to help you gradually return to a normal lifestyle. Always follow the exercise, diet, and medication plan prescribed by your doctor.

During a heart attack, act immediately. Take these steps:
By. Mayoclinic

Call for emergency medical help. If you even suspect you're having a heart attack, don't hesitate. Immediately call 911 or your local emergency number. If you don't have access to emergency medical services, have someone drive you to the nearest hospital. Drive yourself only as a last resort, if there are absolutely no other options. Driving yourself puts you and others at risk if your condition suddenly worsens.
Take nitroglycerin. If your doctor has prescribed nitroglycerin, take as instructed while awaiting the arrival of emergency medical personnel.
If you encounter someone who is unconscious from a presumed heart attack, call for emergency medical help and, if you have received training in emergency procedures, begin cardiopulmonary resuscitation (CPR). This helps deliver oxygen to the body and brain. If you're not trained in emergency procedures, doctors recommend skipping mouth-to-mouth rescue breathing and proceeding directly to chest compression. Do chest compressions at a rate of 100 a minute.

In the initial minutes, a heart attack can also trigger ventricular fibrillation, a condition in which the heart quivers uselessly. Without immediate treatment, ventricular fibrillation leads to sudden death. The timely use of an automatic external defibrillator (AED) that shocks the heart back into a normal rhythm can provide emergency treatment before a person suffering a heart attack reaches the hospital.

Once you reach a hospital emergency room and it's clear you're having a heart attack, you may be treated with medications, undergo an invasive procedure or both — depending on the severity of your condition and the amount of damage to your heart.

With each passing minute after a heart attack, more tissue is deprived of oxygen and deteriorates or dies. The main way to prevent progressive damage is to restore blood flow quickly.

Medications given to treat a heart attack include:

Aspirin. You may be given aspirin by emergency medical personnel soon after they arrive or as soon as you get to the hospital. Aspirin inhibits blood clotting, thus helping maintain blood flow through a narrowed artery. Take an aspirin yourself while waiting for help to arrive only if your doctor has previously recommended that you do so if you have symptoms of a heart attack.
Thrombolytics. These drugs, also called clot-busters, help dissolve a blood clot that's blocking blood flow to your heart. The earlier you receive a thrombolytic drug following a heart attack, the greater the chance you will survive and lessen the damage to your heart.
Superaspirins. Doctors in the emergency room may give you other drugs which are somewhat similar to aspirin to help prevent new clots from forming. These include medications such as clopidogrel (Plavix) and others called platelet IIb/IIIa receptor blockers.
Other blood-thinning medications. You'll likely be given other medications, such as heparin, to make your blood less "sticky" and less likely to form more dangerous clots. Heparin is given intravenously or by an injection under your skin and is usually used during the first few days after a heart attack.
Pain relievers. If your chest pain or associated pain is great, you may receive a pain reliever, such as morphine, to alleviate your discomfort.
Nitroglycerin. This medication, used to treat chest pain (angina), temporarily opens arterial blood vessels, improving blood flow to and from your heart.
Beta blockers. These medications help relax your heart muscle, slow your heartbeat and decrease blood pressure making your heart's job easier. Beta blockers can limit the amount of heart muscle damage and prevent future heart attacks.
Cholesterol-lowering medications. Examples include statins, niacin, fibrates and bile acid sequestrants. These drugs help lower levels of unwanted blood cholesterol and may be helpful if given soon after a heart attack to improve survival.
Surgical and other procedures
In addition to medications, you may undergo one of the following procedures to treat your heart attack:

Coronary angioplasty and stenting. Emergency angioplasty opens blocked coronary arteries, letting blood flow more freely to your heart. Doctors insert a long, thin tube (catheter) that's passed through an artery, usually in your leg, to a blocked artery in your heart. This catheter is equipped with a special balloon tip. Once in position, the balloon tip is briefly inflated to open up a blocked coronary artery. At the same time, a metal mesh stent may be inserted into the artery to keep it open long term, restoring blood flow to the heart. Depending on your condition, you doctor may opt to place a stent coated with a slow-releasing medication to help keep your artery open.

Coronary angioplasty is done at the same time as a coronary catheterization (angiogram), a procedure that doctors do first to locate narrowed arteries to the heart. When getting an angioplasty for heart attack treatment, the sooner the better. If an angioplasty is performed days or weeks after you've been stabilized with a completely blocked artery, there may not be any benefit.

Coronary artery bypass surgery. In rare cases, doctors may perform emergency bypass surgery at the time of a heart attack. Bypass surgery involves sewing veins or arteries in place at a site beyond a blocked or narrowed coronary artery (bypassing the narrowed section), restoring blood flow to the heart. Or your doctor may suggest that you have this procedure after your heart has had time to recover from your heart attack.
Once blood flow to your heart is restored and your condition is stable following your heart attack, you may be hospitalized for observation. Because physical exertion and emotional upset place stress on your heart, be sure to rest. Visitors are usually limited to family members and close friends.

The goal of emergency treatment of a heart attack is to restore blood flow and save heart tissue. The purpose of subsequent treatment is to promote healing of your heart and prevent another heart attack.

Some hospitals offer cardiac rehabilitation programs that may start while you're in the hospital and, depending on the severity of your attack, continue for weeks to months after you return home. Cardiac rehabilitation programs generally focus on three main areas — medications, lifestyle changes and emotional issues.

How to prevent and treat hearth disease by Cindy Heller

Heart disease is a general term for a number of different diseases, all of which influence the heart in some way. Heart disease is in fact considered as being the leading reason of death nowadays in the United States. Heart disease indeed possesses serious threat to many people. Therefore, it is important to understand the methods to prevent and treat heart disease.

Prevention methods

There is reason to be hopeful because according to experts, heart disease prevention is promising. Even though some risk factors including sex, genetics, and age of a person are not within our control, one can still make an alteration in lifestyle and also change diet so that the odds of heart disease are significantly reduced.
There are also other methods by which heart disease prevention can be achieved. According to what the American Heart Association proposes, one must control obesity even in children and also make a determined attempt to take proper diet that contains enough nutrition. One of the better nutritional supplements you may want to try for heart disease prevention is mangosteen puree that is rich in antioxidants which aid in destroying free radicals that are the reason behind damage to cells and which in turn will result in heart disease.
Good heart disease prevention may also mean controlling the blood pressure and having LDL cholesterol at low levels. The best way to attain these goals is by making appropriate changes to diet and even by taking medications if so recommended by the doctor. Clearly, having low blood sugar levels will consider as heart disease prevention.
Another alternative is to exercise because it is a well known fact that regular exercise can reduce the risks of heart disease. Experts have a tendency to recommend as much exercise as humanly possible at least an hour per day. For many people, this seems like a never-ending task but the truth is this amount of exercise can be attained in ways other than going to the gym. Basically changing some habits, such as walking to work, can make people healthier. Walking is perhaps the easiest, cheapest, and healthiest type of exercise for most people and therefore should be taken advantage of.
The best heart disease prevention may not be a solitary course of action; rather, one may decide to have many strategies combined into one that will prove to be more effective. You can select approaches such as changes in diet, together with reducing excess weight and also maintaining blood sugar levels as well as taking nutritional supplements that are suggested by health experts.

Treatment options for heart disease

If you have heart disease then you will have to have some types of heart disease treatment in order to solve your problem. There are various heart disease treatment options that are available nowadays. The first treatment is of course prevention as explained previously.
However, if your heart disease is serious, than most probably you will also have to use more serious techniques of heart disease treatment. This includes medical treatment, which will usually be started straight away, even before an exact diagnosis of a heart problem is made.
This medical treatment may comprise of oxygen from a tube in the nose, oxygen through a face mask, nitroglycerin under the tongue, pain medicines, and aspirin. There are also clot dissolving medications which are often given, and the earlier these drugs are given, the higher the chances of opening the blocked artery and defending the cardiac muscle from further injury.
Cellular therapy, for example, is considered as being a potential treatment for heart disease. This is due to cellular products have been revealed to hold great potential for the treating of injured and diseased tissues in the body. They come from many sources, such as stem cells from bone marrow, peripheral blood, and myoblasts from skeletal muscle cells. The research so far has shown that this cellular therapy offers amazingly positive results, and so with additional research and more advancement, in the future this just may be known as the cure for heart disease.
Surgery can be executed on those who experience heart disease at any age although other methods are preferable. Surgery is necessary for those who do not react to their medications or whose condition worsens radically. In some situations, surgery is the only method to amend the problem and give the patient a probability of good health. In uncommon cases, repeat surgery is needed afterward to rid the body of excess fluids that have developed in the chest.
Heart surgery can be wearing and the healing period can be slow so it is no surprise to find out that a huge number of people who suffer from heart disease which needs surgery are interested in less invasive surgery. Less invasive surgery for heart disease can involve smaller incisions, less pain, and a much faster healing period. Not only does this type of surgery involve shorter hospital stays, it can also reduce the risks of complications to the patient during and after the operation.
There are many resources that are available if you want more information on the treatment of heart disease. The most significant thing of all is to keep a healthy lifestyle, a healthy and nutritious diet, and plenty of exercise. By keeping a healthy lifestyle you will not only be guarding yourself against heart disease but as well against all illnesses and health conditions in general.

Limiting Heart Muscle Damage

Treatments for a heart attack work to open the blocked artery to restore blood flow as fast as possible to prevent or limit damage to the heart muscle, and to lessen the chance of a repeat attack. The main treatments are thrombolytic ("clot-busting") therapy, other medications, and special procedures, such as angioplasty and coronary artery bypass surgery.
To be most effective, these treatments must be given fast–within 1 hour of the start of heart attack symptoms. Acting fast can save your life and limit damage to your heart.
To learn more about treatment:
. Thrombolytic therapy.
. Other medications.
. Special procedures.

Thrombolytic Therapy

"Thrombolytic" or "clot-busting" therapy is used to stop a heart attack in its tracks. The drugs prevent or limit heart muscle damage by dissolving clots that block an artery. This opens up the artery and restores the blood flow.
Clot-busting drugs must be given immediately after heart attack symptoms begin. The sooner they are started, the more good they do-and the greater the chances are of a full recovery. To be most effective, they need to be given within 1 hour of the start of heart attack symptoms.

Other Medications

Besides thrombolytic, or clot-busting, drugs, other medications also are used to treat a heart attack and ischemia, as well as to ease chest pain. These drugs include aspirin, nitrates, such as nitroglycerin, and beta blockers.

  • Aspirin. Aspirin is now given to all patients who arrive at the hospital emergency department with a suspected heart attack. Aspirin acts to thin the blood and lessen the size of a blood clot during a heart attack.
  • Nitrates, including nitroglycerin. This relaxes blood vessels and stops chest pain.
  • Beta blockers. These reduce nerve impulses to the heart and blood vessels. This makes the heart beat more slowly and with less force.

Special Procedures

Doctors sometimes need to do a special procedure to improve blood flow to the heart muscle when the heart’s artery, or arteries, are narrowed or blocked. Two commonly used procedures are coronary angioplasty and coronary artery bypass graft surgery. These procedures can be done during a heart attack or later.
While a Heart Attack is happening, the sooner these procedures are done, the greater the chances of saving heart muscle and of surviving a heart attack.

Here's more on these special procedures :
  • Coronary angioplasty, or balloon angioplasty. In this procedure, a fine tube, or catheter, is threaded through an artery into the narrowed heart vessel. The catheter has a tiny balloon at its tip. The balloon is repeatedly inflated and deflated to open and stretch the artery, improving blood flow. The balloon is then deflated, and the tube is removed.
    Doctors often insert a stent during the angioplasty. A wire mesh tube, the stent is used to keep an artery open after an angioplasty. The stent stays permanently in the artery.
    In up to a third of those who have an angioplasty, the blood vessel becomes narrowed or blocked again within 6 months. This is more likely to happen if you smoke, or have diabetes or unstable angina. Vessels that reclose may be re-opened with another angioplasty or need a coronary artery bypass graft. Even an artery with a stent can reclose.
  • Coronary artery bypass graft operation. Also known as "bypass surgery," the procedure uses a piece of vein taken from the leg, or of an artery taken from the chest or wrist. This is attached to the heart artery above and below the narrowed area, thus making a bypass around the blockage. Sometimes, more than one bypass is needed.
    Bypass surgery may be needed due to various reasons, such as an angioplasty that did not sufficiently widen the blood vessel, or blockages that cannot be reached by, or are too long or hard for, angioplasty. In certain cases, bypass surgery may be preferred. For instance, it may be used for persons who have both coronary heart disease and diabetes.
    A bypass also can close again. This happens in more than 10 percent of bypass surgeries, usually after 10 or more years.

Who's At Risk?

Heart attacks strike both men and women. However, some persons are more likely than others to have a heart attack because of their "risk factors." Risk factors are behaviors or conditions that increase the chance of a disease. Some of the risk factors for heart attack are beyond your control, but most can be modified to help you lower your risk of having a first–or repeat–heart attack.

Factors that increase the risk of a heart attack are :

Factors you cannot control
· Pre-existing coronary heart diseases, including a previous heart attack, a prior angioplasty or bypass surgery, or angina
· Age-In men, the risk increases after age 45; in women, the risk increases after age 55.
· Family history of early heart disease-a father or brother diagnosed before age 55; or a mother or sister diagnosed before age 65.

Factors you can control
· Smoking.
· High blood pressure.
· High blood cholesterol.
· Overweight and obesity.
· Physical inactivity.
· Diabetes.

Risk factors do not add their effects in a simple way. Rather, they multiply each other’s effects. So, it is very important to prevent or control risk factors that can be modified. If you have one or more of these factors, see your health care provider to find out how to reduce your risk of having a first or repeat heart attack.

What is a heart attack?

What Is A Heart Attack?

The heart works 24 hours a day, pumping oxygen- and nutrient-rich blood to the body. Blood is supplied to the heart through its coronary arteries. In coronary heart disease (CHD), plaques or fatty substances build up inside the walls of the arteries. The plaques also attract blood components, which stick to the artery wall lining. Called atherosclerosis, the process develops gradually, over many years. It often begins early in life, even in childhood.
The fatty buildup or plaque can break open and lead to the formation of a blood clot that seals the break. The clot reduces blood flow. The cycle of fatty buildup, plaque rupture, and blood clot formation causes the coronary arteries to narrow, reducing blood flow.
When too little blood reaches the heart, the condition is called ischemia. Chest pain, or angina, may occur. The pain can vary in occurrence and be mild and intermittent, or more pronounced and steady. It can be severe enough to make normal everyday activities difficult. The same inadequate blood supply also may cause no symptoms, a condition called silent ischemia.
If a blood clot suddenly cuts off most or all blood supply to the heart, a heart attack results. Cells in the heart muscle that do not receive enough oxygen-carrying blood begin to die. The more time that passes without treatment to restore blood flow, the greater the damage to the heart.
