Cholesterol is a fatty substance found among the lipids in the bloodstream and in cells throughout the body. Cholesterol is not inherently "bad" - in fact, cholesterol is a naturally occurring substance in the body that plays a critical role the formation of cell membranes and the manufacture of hormones. But the body only needs a small amount of Cholesterol to carry out these functions. When the body has too much Cholesterol that is when it becomes a potential health risk. To see why this is, it helps to understand a bit more about how cholesterol interacts with the body. Cholesterol and other fats cannot dissolve in the blood stream. So, they need to be transported in to and out of cells by special carriers called lipoproteins. Cholesterol is carried by two of these, low-density lipoprotein (LDL) and high-density lipoprotein (HDL). LDL is the primary carrier of Cholesterol, while HDL moves only about one third of the cholesterol in the body. When the amount of cholesterol in the blood stream increases, the body needs to create additional lipoproteins to transport them. LDL has become known as "bad" cholesterol because when there is too much of it in the blood stream it tends to build up on the arterial walls, forming plaque. This plaque buildup clogs and hardens the arteries, a condition known as atherosclerosis. This can lead to heart attack or a stroke. HDL has been dubbed "good cholesterol" because it seems to actually aid in removing cholesterol from the body, by carrying it away from the arteries and back to the liver, where it's passed from the body. Determining your cholesterol level is easy, and can be done with a simple blood test. The "normal level" of cholesterol for any individual depends upon their age, weight, and sex, but typically an LDL level of above 160 is considered high. Similarly an HDL level below 40 would usually be considered too low. Either high LDL levels or low HDL levels can put you at risk for plaque buildup. Although our bodies do naturally make a small amount of cholesterol, most of our cholesterol comes from ingesting fatty foods. The first and easiest way to reduce cholesterol is to restrict your fat intake. High cholesterol is an important factor in heart disease and stroke, and managing your cholesterol is an important part of a healthy lifestyle. The good news is that there are many effective ways to manage high cholesterol, as you can see from other films in this library. However, an important first step toward a heart healthy lifestyle should be to see your doctor and find out your Cholesterol level.More »

Is it true about red wine & heart attack prevention? Many are curious to know. To find the answer, watch this video and increase your knowledge.

"If only preventing a heart attack were as easy as sipping on a nice pinot noir. Well, it may be.According to much enjoyed research, red wine -- in moderation -- is thought to prevent heart disease, which in turn, could prevent heart attacks. One study, conducted by researchers from the Israel Institute of Technology found that blood flow to the heart was improved when participants drank at least one glass of red wine a day for three weeks. This is because cell death, known as apoptosis, was reduced and antioxidants in the wine may help protect the lining of blood vessels in the heart.Another study, done by researchers at the University of Ulm in Germany, found that resveratrol, a substance in red wine, may reduce risk of cardiovascular disease in moderate drinkers. Seems that resveratrol increases levels of ""good"" heart-protecting HDL cholesterol and protects against artery damage. Resveratrol is also thought to prevent blood clots, which are a main cause of heart attacks.To gain the benefits, the researchers recommend that men average about 10 ounces of wine a day and women, about 5 ounces. Remember though, neither the American Heart Association nor the National Heart, Lung, and Blood Institute recommend that you START drinking alcohol to prevent a heart attack. Alcohol can be addictive, and contribute to a wide range of health problems, including high blood pressure, cardiomyopathy, liver damage, obesity and various cancers If you'd rather not indulge in a glass of wine, you can opt for a glass of grape juice, since resveratrol is found in the grape's skin, or for adding peanuts, blueberries and cranberries into your diet, all of which contain resveratrol,If you are on medication or have chronic health issues, talk with your doctor about the potential risks and benefits of drinking wine.

Heart Disease affects more than 20 million Americans, and is one of the leading causes of death in this country. But what exactly does the term heart disease mean? When most people talk about heart disease, they usually mean coronary artery disease, the illness which causes both angina and heart attacks. However, there are also other conditions that can affect our cardiovascular system, such as congestive heart failure and aneurysms. To better understand each of these diseases, it helps to review how the heart works. Basically the heart is a pump. Its purpose is to circulate blood to all of the organs of the body. The heart is made up of four chambers, two ventricles that pump blood out of the heart, and two atria, which hold the blood returning to the heart. The heart receives its entire supply of blood through the three coronary arteries. Coronary artery disease occurs when there is a buildup of fatty plaque known as atherosclerosis inside the coronary arteries. When the buildup is sufficient to restrict, but not stop, blood flow into the heart, the result is angina, a discomfort or pain in the chest. Angina isn't actually a disease, but rather is a symptom of coronary artery disease. When the buildup of atherosclerosis is sufficient to interrupt blood flow to the heart, the result is the death of heart muscle cells, commonly known as a heart attack. So, both angina and heart attacks are really caused by the buildup here, in the coronary arteries. Congestive Heart Failure, on the other hand occurs when the heart is pumping inefficiently and can no longer meet the body's need for blood. The ventricles, which are the main pumps within the heart, often are to blame for the insufficient blood flow. The "congestive" part of Congestive Heart Failure comes from the backup of blood in the veins leading into the heart. This backup causes the kidney to retain fluids. Other, less common diseases affect other parts of the heart. For example, when a patient is suffering from an aneurysm, that means that their aorta has swollen, creating a bulge in the artery. Understanding heart disease is an important first step towards prevention. It may also be worthwhile to learn how high blood pressure and cholesterol can impact your heart health, and to incorporate some of the lifestyle tips on preventing heart disease available in other videos in this library. Remember, heart disease is both complex and serious, and you should always consult a physician if you are concerned about your cardio health.

Coumadin is the brand name for warfarin, an anticoagulant, or blood thinner, which was approved by the FDA in 1952. Warfarin is a prescription medication which is available as a generic drug and under the brand name Coumadin. Warfarin is an anticoagulant-or blood thinner-which means it helps to keep blood from clotting. Here's how warfarin works: Vitamin K helps stop excessive bleeding through clot-formation. Sometimes though, clots can form too readily and block blood supply to vital organs. When that happens, warfarin hinders the action of Vitamin K, resulting in thinner blood and fewer clots. Warfarin is often prescribed for people who have suffered heart attacks. It can be used to prevent the formation of a pulmonary embolism, which is a blood clot in the lungs, and to prevent venous thrombosis, which is a clot in the veins. Patients with rapid or irregular heartbeats and those who have artificial heart valves may also take this medication as a precautionary measure. Warfarin can be taken orally in tablets from one to ten milligrams. While taking warfarin, you should be prepared for frequent blood tests to measure your clotting time. The two most serious side effects of warfarin are gangrene and internal bleeding, but be sure to ask your doctor for a complete list. And, tell your physician immediately if you experience signs of internal bleeding, like blood in your urine, fainting spells, paralysis, or any other significant changes. Warfarin should not be taken in conjunction with aspirin or other drugs that thin the blood, like Ibuprofen. Ask your doctor for a full list of medications and conditions that should not be combined with warfarin. Because of its anticoagulant effects, Coumadin can be very effective in treating blood clots. However, it can be dangerous too, resulting in excess bleeding. Always use warfarin under the direct care of a physician. Please ask for and review all of the patient information provided by your doctor before taking warfarin.

Lowering cholesterol can often be achieved through a healthy lifestyle. High LDL levels are the main cause for high cholesterol and can be reduced with the help of fiber rich foods, fruits, whole grain and vegetables. Watch our video for more information.

Whether you're in the eighteen percent of Americans with high cholesterol or not, you can benefit from living a low-cholesterol lifestyle. A low-cholesterol lifestyle involves making conscious decisions to eat, play and live in a way that will help to lower your levels of harmful LDL cholesterol. Cholesterol is a fatty substance that is found in the body. Some cholesterol is necessary for basic functions, but here's the catch: The body usually makes all the cholesterol it needs. With this in mind, it makes sense to lower your intake of fats. In fact, it's best to limit total fat intake to less than 30 percent of your daily calories. All fats aren't created equal though, and fall into different categories: Saturated, unsaturated, and trans-fatty acids. Saturated fat is found primarily in foods from animals, like beef, eggs, milk and cheese. Because saturated fat is the main dietary cause of high blood cholesterol, it is best to limit it to less than 7 percent of your daily calories. Saturated fats and unsaturated fats are distinguishable by the way their carbon atoms bond. A double bond between carbons leads to lower amounts of hydrogen in the fat due to fewer bonding sites. Saturated fats, which have no double bonds, are literally saturated with hydrogen. Unsaturated fats, on the other hand, DO have double bonds and can be further divided into monosaturated fats, which have one, and polysaturated fats, which have two. These unsaturated fats may actually help lower blood cholesterol when they replace saturated fats in the diet. The unsaturated fats are found in many fish, nuts, seeds and plant oils. They should make up about half of your daily fat intake. Perhaps the worst fats are the trans-fatty acids and hydrogenated fats. Trace amounts of these are found in animal products. They are also formed during the process of hydrogenation, which is how margarine, shortening and cooking oils are made. Understanding and limiting your intake of fats is an important step toward a cholesterol-friendly diet, but it's essential to increase your fiber, too. Consuming 25 to 30 milligrams of fiber-rich foods like fruits, vegetables and whole-grains daily can help lower LDL cholesterol. A healthier diet is a great start, and exercise can make your program even more efficient! Aim for thirty minutes at least three times a week. While physical activity is not known to impact bad LDL cholesterol, it does increase the level of HDL, or good cholesterol, in the blood, lowering the risk of heart disease. And finally-one of the most important things you can do to lower your cholesterol levels is to stop smoking, or to decrease the amount of time you spend around smokers. Smoking is a double blow...it lowers levels of HDL cholesterol and makes your body resistant to heart-healthy exercise. High LDL cholesterol is bad news, but leading a cholesterol-lowering life can help! Remember to see your doctor before you begin a new exercise or diet program.More »

When someone has a heart attack, they need to receive medical attention as soon as possible. How can you tell when what you are experiencing is a heart attack? How should you respond? It can sometimes be hard to differentiate between the symptoms of a heart attack and more common occurrences like chest pain or severe heartburn. Fortunately, there are some simple ways to help tell the difference. While all three conditions are characterized by intense pain in and around the chest, there are several distinctive symptoms associated with a heart attack. Often, people suffering from a heart attack describe the pain they feel as radiating outward and leading to intense pain in the back, throat, or jaw. There can also be pain running down the left arm. Many heart attack sufferers also feel weakness and a distinct shortness of breath because the heart is no longer effectively circulating blood. Nausea, vomiting, a feeling of dizziness, and profuse sweating are also common symptoms of heart attack. All of these symptoms can be better understood in the context of what happens during a heart attack. The heart itself is a muscle, and its job is to circulate blood throughout the body. Oxygen-rich blood comes into the heart through two passages, known as the coronary arteries. Heart attacks occur when the fatty deposits or plaque build up in these arteries rupture and cause a clot in the artery. Without this oxygen-rich blood, the heart muscle begins to die, which is the source of the pain during a heart attack. Given this, it is not surprising that one other common symptom of heart attack is a rapid or an irregular heartbeat. The right response to a heart attack is simple. First, call 911 immediately, and ask for emergency help. Second, while you are waiting for the ambulance to arrive, take one regular strength aspirin tablet. This will prevent blood clotting that can worsen a heart attack. Being able to quickly recognize a heart attack will help you to respond fast, and the sooner you get proper treatment, the better your chances are of avoiding permanent damage to the heart. Remember, heart disease is both complex and serious, and you should always consult a physician if you have concerns.

Have you been experiencing an irregular, rapid heartbeat - up to 350 to 600 beats a minute? If so, it may be atrial fibrillation - a disruption of heart rhythm that can deprive the body of oxygenated blood and may cause a stroke or heart attack. Aside from a rapid heartbeat, other common symptoms of this cardiac condition include: decreased blood pressure, shortness of breath and chest pains. Some people though, may have no symptoms. If your symptoms do send you to the doctor's -and they should -- he or she will ask about your medical history and sensations, and conduct tests to confirm that atrial fibrillation is the cause of your discomfort. If you have chest pain, however, don't go to the doctor, head for the ER. Tests to diagnose atrial fibrillation include: An electrocardiogram to measure electrical impulses of the heart. If there is a lull or a spike in these impulses, chances are atrial fibrillation is the cause. An echocardiogram, in which sound waves produce a video image of the heart in motion. These images show how blood is pumped through the heart, revealing any delays or increases, as well as any structural damage. If abnormalities are found, the doctor may suggest wearing a Holter monitor, a small device that records the heart's electrical activity, for a day or two as you go about your regular routine. Or an event recorder, which is similar to the Holter monitor but is worn for about a month and only records the heart's electrical activity when symptoms are present. Blood tests and chest X-rays are then typically administered to rule out other conditions. For example, a blood test can reveal that the symptoms are the result of thyroid disease and an X-ray can confirm various other heart and lung conditions. For those who may have no symptoms, the condition is typically uncovered during a routine visit to the doctor. For information on atrial fibrillation treatment options, check out other videos on this site.More »

More than 4 million people in the United States suffer from congestive heart failure. This is a condition in which the heart's pumping power is weaker than normal. Learn more in this video.

Congestive Heart Failure affects over 5 million Americans, but it is still the most commonly misunderstood kind of heart disease. So what exactly is Congestive Heart Failure? Congestive Heart Failure is a condition in which the heart's pumping power is weaker than normal, and cannot pump enough blood and oxygen throughout the body. When the heart is unable to pump blood as effectively as usual, the movement of blood through the body slows. At this point, blood begins to back up in the veins returning to the heart, which causes congestion in the chest tissue. It is from this feeling of congestion that congestive heart failure gets its name. The most common cause of Congestive Heart Failure is coronary artery disease, the same condition responsible for Angina and Heart Attack. Events which damage the heart, such as a heart attack can also lead to congestive heart failure. As well, congestive heart failure often comes about when a patient has a condition that chronically overworks the heart, like high blood pressure or diabetes. One of the most common symptoms of congestive heart failure is water retention, which occurs because of the reduced blood flow to the kidneys. This water retention causes swelling, known as Edema, which occurs most commonly in the legs and ankles. Other typical symptoms of congestive heart failure include shortness of breath, congested lungs, fatigue, and an irregular or rapid heartbeat. Doctors who suspect that a patient has CHF can attempt to confirm that diagnosis with a variety of blood tests or an EKG, which measures and charts the electrical impulses traveling through the heart. Managing Congestive Heart Failure begins with some lifestyle changes. Patients can improve their quality of life by adopting a healthy diet low in sodium and cholesterol, A moderated approach to daily life, with planned rest and the careful avoidance of overexertion is recommended. As well, several kinds of medication can be helpful, including beta-blockers to improve the heart's pumping action If a specific cause for the Heart Failure can be discovered your doctor will treat that root cause. In some cases a surgical procedure can be the best course of action, such as when the patient has a defective heart valve or when a heart transplant is necessary. Most people with mild to moderate Congestive Heart Failure can lead normal and productive lives, especially if the disease is found in its earliest stages. If you suspect you may be suffering from CHF or have concerns about your heart health, please seek the advice of your physician or other qualified healthcare provider.

Make heart health a part of your life. Whether you're suffering from an existing condition or you just want to engage in a healthy, disease-preventive lifestyle, these tips can help. Even though 20 million Americans suffer from some form of Heart Disease, simple changes in diet and exercise can help you to keep your heart healthy. The leading cause of cardiovascular disease is high cholesterol, which affects a staggering 100 million Americans. Let's take a moment to understand what cholesterol is. While your body produces a small amount of cholesterol naturally, to make cell tissues and produce certain hormones, fatty foods are the primary source of cholesterol for most people. When someone has too much cholesterol in their blood it can lead directly to a buildup of "plaque" in your arteries. This is what is known as coronary artery disease, and can lead to a heart attack. There are two types of cholesterol. LDL or "bad" cholesterol is the type of cholesterol which causes plaque buildup and clogs arteries. HDL, also known as "good" cholesterol does not contribute to plaque buildup and actually removes cholesterol from the bloodstream. This explains why too much LDL cholesterol is bad for the body, and why a high level of HDL can be beneficial, as you can see here. It is not just your overall cholesterol level, but how that cholesterol is split between the LDL and HDL cholesterols, that provide a real sense of your risk for heart disease. I'm going to tell you about foods that will boost your good cholesterol or HDL and also guide you away from foods that will raise your overall and LDL cholesterol levels. Certain foods are full of good fats that contribute to good HDL cholesterol. But some foods are not so good for you, like.....Exercise is also an important part of any plan to lower your cholesterol levels. Let me demonstrate some exercises you can do in your own home that can help you on your path to heart health. Make cardio health the center of your plan for a good and long life.
