Artificial Heart: Build a Better Heart

In some cases, heart disease may be so severe that the patient can not stand waiting for a donor heart. Medical scientists have developed electronic devices such as defibrillators, pacemakers and artificial heart models that can keep patients alive until the heart becomes available.

One of the most famous is the "Jarvik-7" artificial heart, named after its designer Robert K. Jarvik, an American doctor. Designed to function like a natural heart, Jarvik-7 has two pumps (such as the ventricles), each with a disk-shaped mechanism that pushes blood from the valve inlet to the outlet valve.

The action of the artificial heart is fully similar to the action of the natural heart. There is, however, one major difference: the heart muscle of living nature, while the artificial heart is plastic, aluminum, and Dacron polyester. As a result, artificial heart requires some external source of "life." An external power system to energize and organize the pump through a system of compressed air hoses that enter the heart through the chest. Since the system is complicated and open to infection, the use of artificial heart intended to be temporary.

The Jarvik-7 was first used in the early 1980s. However, previous artificial hearts dates back to the mid-1950s. In 1957, a team of scientists, led by Willem Kolff, a Dutch-born physician, they are tested in animal models to identify the problem. In 1969, a team led by Denton Cooley of the Texas Heart Institute successfully kept a human patient alive for more than sixty hours with their model. During the following years, the idea of ​​a permanent, not temporary, implantation began to take hold.

In 1982, a team led by William DeVries of the University of Utah embed the Jarvik-7 into patient Barney Clark who called. For various medical reasons, transplantation surgery is not an option for Clark. Therefore, it is a prime candidate for a permanent artificial heart. He survived with the Jarvik-7 for 112 days.

Since then, the development of improved artificial heart continue. One possibility is the heart that electrical power from a small wearable batteries that do not require a break in the skin. Maybe, someday, the artificial heart will be a choice, realistic permanent survival.

Open Heart Surgery

Open Heart Surgery
As the patient's chest cavity is opened, note the steam rising as the surgeon cauterizes the blood vessels. The patient is attached to a heart-lung machine that made the blood circulation while the heart is stopped. Once the heart stops beating, the arteries (arterial milk) of the chest cavity is grafted to the heart at both ends, through the blocked coronary artery. Finally, the patient is taken off of heart-lung machine. The heart begins to beat again.

Invasive Procedures

The most invasive procedure is Open Heart Surgery.

If diet and exercise are not effective in treating heart disease, medication is usually prescribed. If heart disease is still the cause of pain, invasive procedures are usually performed. There are several types of procedures that can be used to improve blood supply to the heart.

To find the clogged arteries, coronary arteriography (mapping of the coronary artery) is performed by using a procedure called cardiac catheterization. A doctor guides a thin plastic tube (called a catheter) through an artery in the arm or leg and leads into the coronary arteries. Then, the doctor injects a liquid dye through the catheter. Fluid visible in the X-ray dye to record the trip as it flows through the arteries. By mapping the flow of dye, the doctor identifies blocked areas. Once mapping is complete, your doctor can determine the best course of action.

One possibility is called percutaneous transluminal coronary angioplasty (PTCA), also known as angioplasty or balloon angioplasty. The doctor inserts a catheter and a guide to the blocked area of ​​arteries. Then a second catheter with a tiny balloon at the tip is passed through the first catheter. Once the tip reaches the blocked balloon, the balloon expands. This compresses the plaque build-up, widening the artery to blood flow. Finally, the balloon deflated and removed.

Another possibility is that coronary artery bypass graft surgery. A surgeon takes a healthy blood vessel from another part of the body (usually in the leg or chest wall) and use it to build a detour around the blocked coronary artery. One end of the vessel is grafted (attached) just below the blockage while the other end is grafted just above the blockage. As a result, blood can flow to the heart muscle again. In a double bypass surgery, two grafts done. In the third bypass, three grafts. Inside, four quadruple grafts.

The most radical possibility is that a heart transplant or a part of the heart is required. When healthy people die, their hearts can still be used. Patient's diseased heart is removed and a healthy donor heart is then attached. This operation is complicated because so many blood vessels must be detached and re-installed. When the operation progresses, the patient is connected to a heart-lung machine to keep their blood circulating. After surgery, there is still a risk that the patient's system may reject the new heart. Types of networks to be very suitable for transplantation to be successful. As a result, the number of transplants performed quite low.

Many patients do not survive waiting for a donor heart. Medical scientists have developed an artificial heart that can be used to keep patients alive for a short time until a donor heart becomes available. Scientists are also experimenting with animal-to-human heart transplant. In 1984, twelve-day-old baby girl, known as Baby Fae, received a seven-month baboon heart. A team of medical scientists from Loma Linda University in California conducted the operation. Although Baby Fae died twenty-one days later, the experiment provides a valuable research information for the future.

Heart Attak : An Explosive Situation

A heart attack is sudden. The cause of heart attacks are not. Years of heart-healthy habits suddenly, unexpectedly, to catch up with you. Anywhere. At any time. Diseased heart is like a ticking time bomb. Heart attack is a blast.

Technically, a heart attack occurs when the supply of nutrient-rich blood to the heart muscle decreases or stops. If the blood supply is turned off for a long time, muscle cells die from lack of oxygen. If the dead cells are sufficient, the victim will also dead. Often, only a fraction of the heart muscle deprived of oxygen so that victims can recover.

Why is the blood supply to reduce or stop? There are many possibilities. One of the most common is arteriosclerosis, arterial disease. If blood can not flow through blood vessels, can not nourish the body and heart.

Is there a way to predict heart attacks? Angina pectoris or chest pain, is a warning sign of possible heart attack. Any chest pain should be taken seriously and investigated.

A heart attack is frightening for both the victim and his victim. Be Saver Heart by studying the best ways to help heart attack victims.

Heart Disease: One Of Millions

What happens if you ignore the recommended healthy heart habits? Probably not. Many people live long without paying much attention to their hearts. However, it is more likely that you will develop some form of heart disease. Millions of Americans suffer from some form of heart disease. The statistics are staggering. Generally, people suffering from high blood pressure. Some suffer from heart disease due to diabetes. Others develop an arrhythmia, murmur, or irregular heartbeat. Increasingly, women become a larger percentage of patients with heart disease.

How do you know if you have heart disease? Consult with your doctor. If you do not, eventually your heart will tell you. A heart attack is heart way of letting you know that something is seriously wrong. Occasionally, heart disease is so severe that doctors decided that surgery is needed.

Hopefully, you will decide to follow the recommended healthy heart habits. If you do, you do not have to worry much about heart disease. It's a decision worth making.

Heart Disease in Women

In recent years, medical science has focused much attention on the specific impact of heart disease in women. Historically, heart disease is considered as a disease predominantly of men. Today, heart disease has become an equal opportunity killer.

Hypertension

Hypertension

There is no "ideal" blood pressure. However, there are many "normal" blood pressure readings. Generally, a reading of less than 120 and 80 indicates that you need not worry. If one or both of the amounts equal to or greater than 120 over 80 for a period of time, you have high blood pressure, or hypertension.

Hypertension is dangerous because it causes the heart to work extra hard. This strain contributes to heart attacks and strokes. When the heart was forced to work extra hard for a long time, it tends to enlarge. A little big heart to function properly, but the heart which can not be significantly enlarged. High blood pressure also causes damage to the arteries, causing arterial disease.

Hypertension can be treated. Mild cases of hypertension can be treated through behavior modification such as changing diet and increasing exercise. More severe cases of hypertension require medications like diuretics, beta blockers, ACE inhibitors and calcium channel blockers. Each type of chemical works differently in an attempt to bring blood pressure back to normal range. For example, diuretics rid the body of excess fluid and salt while beta blockers reduce heart rate and cardiac output of blood.

Please note that this is a general statement about hypertension. For individuals, it is important that you consult a medical professional.

Diabetes

Diabetes

Although diabetes is not really a form of heart disease, often contributes to heart disease. Diabetes occurs when the body is unable to produce or respond properly to insulin needed to regulate glucose (sugar). Besides contributing to heart disease, diabetes also increases the risk of developing kidney disease, blindness, nerve damage, and damage to blood vessels. More than 80 percent of people with diabetes die of some form of heart or blood vessel disease.

There are two forms of diabetes: juvenile diabetes and adult-onset diabetes. Adult-onset diabetes associated with obesity and may be delayed or controlled with proper diet and exercise.

There is no cure for diabetes. However, diabetes can be controlled through changes in eating habits and exercise program. Drugs are also available. However, even if the diabetes under control, still contributes to heart disease.

Diabetes or diabetes or diabetes is a disease characterized by blood glucose levels that exceed the normal (hyperglycemia) due to lack of insulin the body both absolute and relative terms.

Many consider that diabetes is a hereditary disease but from a number of people with diabetes is very little recorded because it is caused by hereditary factors. Diabetes is generally caused by the uncontrolled consumption of food or as a side effect of the use of certain medications.


The following factors can cause a person at risk for diabetes:

1. Heredity
2. Overweight / obesity usually occurs at age 40
3. High blood pressure
4. Figures Triglycerid (a type of fat molecule) High
5. High cholesterol levels
6. Modern lifestyles are likely to consume the instant food
7. Smoking and Stress
8. Consume too many carbohydrates
9. Damage to pancreatic cells 

There are many symptoms of diabetes, even for diabetes type 1 and type 2 diabetes have different symptoms. But in this occasion will focus on the most common symptoms of diabetes.

• Quick dry throat and fatigue. People with diabetes will quickly feel thirsty, why? Because they will lack of glucose, most of the glucose is not used in the body for energy, but discarded in the urine (pee)
• Frequent urination. Traces of glucose metabolism in the urine should not be removed even released, so that more and more on mass production of urine the kidneys.
• Blurred vision. 've Not eaten all day and blurred vision? That's if you are deficient in glucose, no energy for the body.
• Nausea and vomiting. For some patients will feel nausea and vomiting, especially if the control is too much food to glucose
•  Sudden weight loss. Not surprisingly, you can certainly use their own reasoning, because for people with diabetes mellitus little body manages glucose into energy.

Arterial Disease

High blood pressure contributes to arteriosclerosis, a general term for thickening and hardening of the arteries. As we grow older, it is normal to develop some thickening of the arteries. However, if it is advanced arteriosclerosis, heart disease is possible.

One specific type of arteriosclerosis that contributes to heart disease is atherosclerosis, which is derived from the Greek words athero (meaning gruel or paste) and sclerosis (meaning hardness). Atherosclerosis is a progressive disease characterized by the buildup of plaque in arteries. Plaque is made up of fatty substances, cholesterol, cellular waste, calcium, and fibrin. Plaque can partially or totally block blood flow through arteries. Two things can happen: bleeding into the plaque, or formation of clots on the surface of the plaque. If any of these occur and obstruct the arteries, heart attack or stroke may occur.

Several factors contribute to the development of atherosclerosis are high blood pressure, cigarette smoke, and high cholesterol levels. Learn more about atherosclerosis.

Session ended with a "quiet". Spend a few minutes walking slowly to let your body gradually decrease itself. Just like you need to gradually start exercising, you need to gradually begin to relax.

Plans for the next training session. Commit to it. In order for exercise to be truly effective, must be part of your routine. Cardiovascular fitness should be maintained.

Types of Physical Exercise

Types of Physical Exercise

A successful exercise program involves frequent physical activity is rhythmic, repetitive, challenges the circulatory system, and use the large muscles. Exercise program must significantly increase blood flow to the muscles for an extended period of time, promoting cardiovascular fitness. Such exercises are called isotonic, dynamic, or aerobic. If you want to have a healthy heart, you need to do aerobic exercise.

Aerobic activities really "get the blood pumping." As the heart beats faster, blood circulates more quickly, providing additional oxygen to the muscles. This will build strength, or cardiovascular fitness. Some recommended aerobic activity is running, hiking, jogging, cycling, swimming, jumping rope, and roller skating. Some forms of exercise, like weightlifting, can build muscle strength without building cardiovascular fitness.
