Heart disease: Eating a heart-healthy diet
Heart disease is the number one killer of both men and women in the United States. If you are worried about heart disease, one of the most important things you can do is to start eating a heart-healthy diet. Changing your diet can help stop or even reverse heart disease.
At first, it may seem like there is a lot to learn. But you don't have to make these changes all at once. Start with small steps. Over time, making a number of small changes can add up to a big difference in your heart health.
To have a heart-healthy diet:
Eat more fruits, vegetables, whole grains, and other high-fiber foods.
Choose foods that are low in saturated fat, trans fat, and cholesterol.
Limit salt (sodium).
Stay at a healthy weight by balancing the calories you eat with your physical activity.
Eat more foods high in omega-3 fatty acids, such as fish.

What foods are part of a heart-healthy diet?
A heart-healthy diet focuses on adding more healthy foods to your diet and cutting back on foods that are not so good for you.
Healthy foods are ones that are high in vitamins, minerals, fiber, and other nutrients, such as:
Fruits and vegetables.
Beans (including chickpeas and lentils) and whole grains (such as whole wheat, brown rice, oats, rye, bulgur, barley, quinoa, and corn).
Oily fish like salmon, trout, albacore tuna, herring, mackerel, and sardines, which contain heart-healthy omega-3 fatty acids. You can also get omega-3 fats from omega-3 eggs, walnuts, flax seeds, and canola oil.
Foods to limit are ones that are high in:
Unhealthy fats, such as saturated fats, trans fats, and cholesterol.
Saturated fats are mostly found in animal products, such as meats and dairy products.
Trans fats include shortening, partially hydrogenated vegetable oils, and hydrogenated vegetable oils. Trans fats are made when a liquid fat is turned into a solid fat (for example, when corn oil is made into stick margarine). They are found in many processed foods, such as cookies, crackers, and snack foods. Restaurants often use hydrogenated oils for frying foods, so try to limit fried foods when eating out.
Cholesterol is found in animal products, such as eggs, dairy products, and meats.
Salt (sodium). You need some sodium in your diet, but most people get far more than they need. Too much sodium tends to raise blood pressure. Processed foods and fast foods often contain a lot of sodium. Try to limit these foods and eat more fresh foods.
Eating foods that contain unhealthy fats can raise the LDL ("bad") cholesterol in your blood. Having a high level of LDL cholesterol increases your chance of having clogged arteries (atherosclerosis), which can lead to coronary artery disease and heart attack.
Trans fat is especially bad. It both raises the level of "bad” cholesterol and lowers the "good" cholesterol in the blood. Try to avoid trans fat as much as possible.
Test Your Knowledge
If I see "partially hydrogenated vegetable oil" on a food label, I should avoid that food because it contains trans fat.

Why is it important to choose a heart-healthy diet?
Making good food choices can have a big impact on your health. Eating a heart-healthy diet can help you to:
Lower your blood pressure.
Lower your cholesterol.
Reach and stay at a healthy weight.
Control or prevent diabetes.
Improve your overall health.
A heart-healthy diet is not just for people with existing health problems. It is good for anyone. (But children younger than 2 should drink 2% or whole milk, not 1% or skim milk. At age 2, they can switch to low-fat or nonfat dairy products.) Learning heart-healthy eating habits now can help prevent heart disease in years to come.

How to eat a heart-healthy diet
To have a heart-healthy diet:
Eat fruits and vegetables. Eat a variety of fruit and vegetable servings every day. Dark green, deep orange, or yellow fruits and vegetables are especially nutritious. Examples include spinach, carrots, peaches, and berries.
Eat a variety of grain products every day. Include whole-grain foods that have lots of fiber and nutrients. Examples of whole grains include oats, whole wheat bread, and brown rice.
Eat fish at least 2 times each week. Oily fish, which contain omega-3 fatty acids, are best for your heart. These fish include tuna, salmon, mackerel, lake trout, herring, and sardines.
Limit saturated fat and cholesterol. To limit saturated fat and cholesterol, try to choose the following foods:
Lean meats and meat alternatives like beans or tofu
Fish, vegetables, beans, and nuts
Nonfat and low-fat dairy products
Polyunsaturated or monounsaturated fats, like canola and olive oils, to replace saturated fats, such as butter
Read food labels and limit the amount of trans fat you eat. Trans fat raises the levels of LDL ("bad”) cholesterol and also lowers high-density lipoprotein (HDL, or "good") cholesterol in the blood. Trans fat is found in many processed foods made with shortening or with partially hydrogenated or hydrogenated vegetable oils. These foods include cookies, crackers, chips, and many snack foods.
Choose healthy fats. Unsaturated fats, such as olive, canola, corn, and sunflower oils, are part of a healthy diet. But all fats are high in calories, so watch your serving sizes.
Limit salt (sodium). Limit sodium intake to less than 2,300 mg of sodium per day (about one teaspoon). Choose and prepare foods with little or no salt. Watch for hidden sodium in foods.
Eat only as many calories as you need to stay at a healthy weight. Learn how much is a serving, and then check your portion sizes. Limit drinks with added sugar and high-fructose corn syrup. If you want to lose weight, increase your activity level to burn more calories than you eat.
If you drink alcohol, drink in moderation. Limit alcohol intake to 2 drinks a day for men and 1 drink a day for women. See a picture of a standard drink.
Limit added sugar. Limit drinks and foods with added sugar.
When you are eating away from home, try to follow these heart-healthy diet tips.
You can get even more benefit from making diet changes if you also get plenty of exercise and don't smoke.
But you don't have to be perfect, and you don't have to do it all at once. Make one or two changes at a time. As soon as you are used to those, make another one or two changes. Over time, making a number of small changes can add up and make a big difference in your health.
Here are some ideas about how to get started:
Choose whole-grain bread instead of white bread.
Have a piece of fruit instead of a candy bar.
Try to eat at least 5 servings of fruits and vegetables every day. Add one or two servings of fruits and vegetables to your day. Slowly add more servings until you are eating at least 5 servings a day.
Switch from 2% or whole milk to 1% or nonfat milk.
Instead of meat, have fish for dinner. Brush it with olive oil, and broil or grill it.
Switch from butter to a cholesterol-lowering soft spread. Use olive or canola oil for cooking.
Use herbs and spices, instead of salt, to add flavor to foods.
It may take some time to get used to new tastes and habits, but don't give up. Keep in mind the good things you are doing for your heart and your overall health.

Coronary Artery Disease
What is coronary artery disease?
Coronary artery disease occurs when fatty deposits called plaque (say "plak") build up inside the coronary arteries. The coronary arteries wrap around the heart and supply it with blood and oxygen. When plaque builds up, it narrows the arteries and reduces the amount of blood that gets to your heart. This can lead to serious problems, including heart attack.
Coronary artery disease (also called CAD) is the most common type of heart disease. It is also the number one killer of both men and women in the United States.
It can be a shock to find out that you have coronary artery disease. Many people only find out when they have a heart attack. Whether or not you have had a heart attack, there are many things you can do to slow coronary artery disease and reduce your risk of future problems.
What causes coronary artery disease?
Coronary artery disease is caused by hardening of the arteries, or atherosclerosis. Atherosclerosis occurs when plaque builds up inside the arteries. (Arteries are the blood vessels that carry oxygen-rich blood throughout your body.) Atherosclerosis can affect any arteries in the body. When it occurs in the arteries that supply blood to the heart, it is called coronary artery disease.
Plaque is a fatty material made up of cholesterol, calcium, and other substances in the blood. To understand why plaque is a problem, compare a healthy artery with an artery with atherosclerosis:
A healthy artery is like a rubber tube. It is smooth and flexible, and blood flows through it freely. If your heart has to work harder, such as when you exercise, a healthy artery can stretch to let more blood flow to your body’s tissues.
An artery with atherosclerosis is more like a clogged pipe. Plaque narrows the artery and makes it stiff. This limits the flow of blood to the tissues. When the heart has to work harder, the stiff arteries can't flex to let more blood through, and the tissues don't get enough blood and oxygen.
See a picture of a normal artery and an artery narrowed by plaque.
When plaque builds up in the coronary arteries, the heart doesn't get the blood it needs to work well. Over time, this can weaken or damage the heart. If a plaque tears, the body tries to fix the tear by forming a blood clot around it. The clot can block blood flow to the heart and cause a heart attack. See a picture of how plaque causes a heart attack.
What are the symptoms?
Usually people with coronary artery disease don't have symptoms until after age 50. Then they may start to have symptoms at times when the heart is working harder and needs more oxygen, such as during exercise. Typical first symptoms include:
Chest pain, called angina (say “ANN-juh-nuh” or “ann-JY-nuh”).
Shortness of breath.
Heart attack. Too often, a heart attack is the first symptom of coronary artery disease.
Less common symptoms include a fast heartbeat, feeling sick to your stomach, and increased sweating. Some people don't have any symptoms. In rare cases, a person can have a “silent” heart attack, without symptoms.
To find out your risk for a heart attack in the next 10 years, use this Interactive Tool: Are You at Risk for a Heart Attack?
How is coronary artery disease diagnosed?
To diagnose coronary artery disease, doctors start by doing a physical exam and asking questions about your past health and your risk factors. Risk factors are things that increase the chance that you will have coronary artery disease.
Some common risk factors are being older than 65; smoking; having high cholesterol, high blood pressure, or diabetes; and having heart disease in your family. The more risk factors you have, the more likely it is that you have coronary artery disease.
If your doctor thinks that you have coronary artery disease, you may have tests, such as:
Electrocardiogram (EKG or ECG), which checks for problems with the electrical activity of your heart. An EKG can also show signs of an old or new heart attack.
Chest X-ray.
Blood tests.
Exercise electrocardiogram, commonly called a "stress test." This test checks for changes in your heart while you exercise.
Your doctor may order other tests to look at blood flow to your heart. You may have a coronary angiogram if your doctor is considering a procedure to remove blockages, such as angioplasty or bypass surgery.
How is it treated?
Treatment focuses on taking steps to manage your symptoms and reduce your risk for heart attack and stroke. Some risk factors you can't control, such as your age and family history. Other risk factors you can control, such as high blood pressure, high cholesterol, and smoking. Lifestyle changes can help lower your risks. You may also need to take medicines or have a procedure to open your arteries.
Lifestyle changes are the first step for anyone with coronary artery disease. These changes may stop or even reverse coronary artery disease. To improve your heart health:
Don't smoke. This may be the most important thing you can do. Quitting smoking can quickly reduce the risk of heart attack or death.
Eat a heart-healthy diet that includes plenty of fish, fruits, vegetables, beans, high-fiber grains and breads, and olive oil. See a dietitian if you need help making better food choices.
Get regular exercise on most, if not all, days of the week. Your doctor can suggest a safe level of exercise for you. Walking is great exercise that most people can do. A good goal is 30 minutes or more a day.
Lower your stress level. Stress can hurt your heart.
Changing old habits may not be easy, but it is very important to help you live a healthier and longer life. Having a plan can help. Start with small steps. For example, commit to eating five servings of fruits and vegetables a day. Instead of having dessert, take a short walk. When you feel stressed, stop and take some deep breaths.
Medicines may be needed in addition to lifestyle changes. Medicines that are often prescribed for people with coronary artery disease include:
Statins to help lower cholesterol.
Beta-blockers or ACE inhibitors to lower blood pressure.
Aspirin or other medicines to reduce the risk of blood clots.
Nitrates to relieve chest pain.
Procedures may be done to improve blood flow to the heart.
Angioplasty is used to open blocked arteries. It isn't major surgery. During angioplasty, the doctor guides a thin tube (called a catheter) into the narrowed artery and inflates a small balloon. This widens the artery to help restore blood flow. Often a small wire-mesh tube called a stent is placed to keep the artery open. See a picture of angioplasty with stent placement. The doctor may use a stent that is coated with medicine, called a drug-eluting stent. When the stent is in place, it slowly releases a medicine that prevents the growth of new tissue. This helps keep the artery open.
Bypass surgery, which is major surgery, may be used if more than one coronary artery is blocked. It uses healthy blood vessels to create detours around narrowed or blocked arteries.
What else can you do?
To stay as healthy as possible, it is important to:
See your doctor for regular follow-up appointments. This lets your doctor keep track of your risk factors and adjust your treatment as needed.
Take your medicines exactly as prescribed. Do not stop or change medicines without talking to your doctor.
Keep nitroglycerin with you at all times, if your doctor prescribed it for chest pain.
Tell your doctor about any chest pain you have had, even if it went away.
Get the support you need to succeed in making lifestyle changes. Ask family or friends to share a healthy meal or join a stop-smoking program with you. Or ask your doctor about a cardiac rehab program. In cardiac rehab, a team of health professionals provides education and support to help you make new, healthy habits.

Typical symptoms often not present with a heart attack
Typical symptoms often not present with a heart attack
When symptoms are atypical, patients delay seeking medical attention. Since early intervention is the key to a good outcome with a heart attack, people with known or suspected coronary artery disease should be aware of the common "atypical" presenting symptoms reported in this study.
Diabetics may have special risk factors for heart disease
Blood studies now suggest that chronic inflammation in diabetics may predispose to coronary artery disease.

The Echocardiogram
By Richard N. Fogoros, M.D., About.com
The echocardiogram is an extremely useful test for studying the heart's anatomy. It is non-invasive and entirely safe, and when interpreted by well-trained cardiologists, is very accurate.
How is the echocardiogram performed?
The echocardiogram is a simple test to have done. You will lie on an examination table, and a technician will hold a transducer (a device that resembles a computer mouse) against your chest, slowly sliding it back and forth. (The technician will apply a Vaseline-like gel to your chest to aid in sliding the transducer.) You may be asked to roll on your side during the test, or hold your breath for a few seconds. The test takes 30 to 60 minutes to complete.
How does the echocardiogram work?
The transducer that's placed on your chest sends sound waves toward the heart. Like the sonar on a submarine, the sound waves bounce off the heart,and are collected by by the transducer.
These returning sound waves are processed by a computer, assembled into a two-dimensional image of the beating heart, and displayed on a TV screen (which you will be able to see if you wish). By aiming the transducer, the technician will be able to image most of the important cardiac structures.
What are some of the variations used with the echocardiogram?
Echocardiograms are sometimes used in conjunction with stress tests. An echo test is made at rest, and then is repeated during exercise, to look for changes in the function of the heart muscle when exercise is performed. Deterioration in muscle function during exercise can indicate coronary artery disease.
A special microphone (called a Doppler microphone) can be used during the test to measure the velocity of blood flow in the heart. This information can be useful in assessing heart valve function.
A transesophageal echocardiogram can create images of cardiac structures that are difficult to see from a standard echo test, and also offers a way to produce echo images during heart surgery when access to the chest itself is not available to the echocardiographer.
What is the echocardiogram good for?
The echocardiogram reveals important information about the anatomy of the heart. It is especially useful for detecting problems with the heart valves (such as aortic stenosis or mitral valve prolapse). It is also an extremely useful test for evaluating congenital heart disease. The echocardiogram is also a good way to get a general idea of the overall function of the heart muscle.
What is the echocardiogram not good for?
The echo does not image the coronary arteries, and is not useful for detecting coronary artery disease. It is not as accurate as the MUGA scan for measuring overall cardiac muscle function. Various physical variations (a thick chest wall, for instance, or emphysema) may limit the ability to image cardiac structures. These physical variations, however, can be overcome by performing a transesophageal echo test.

Cardiac catheterization and angiography
By Richard N. Fogoros, M.D., About.com
Cardiac catheterization and angiography are tests in which catheters (hollow tubes) are placed into the heart in order to evaluate the anatomy and function of the heart and surrounding blood vessels. So much useful information can be obtained from these tests that they are performed in virtually all patients being considered for bypass surgery or angioplasty and stenting.
How is a catheterization performed?
The patient is brought to the catheterization laboratory and placed on a special examination table. After local anesthesia is given, a catheter is inserted into blood vessels in the groin, arm, or neck. (The catheter is inserted either through a small incision, or by means of a needle-stick. Sometimes, catheters are inserted from more than one site.) The catheter is advanced through the blood vessels to the heart.
Once in the heart, the catheter can be maneuvered to various locations within the heart, and the pressures within various chambers of heart are measured. Blood samples can be withdrawn from different locations in order to measure the amount of oxygen in the blood (unusual variations in blood oxygen can signal a "shunt," or abnormal blood flow within the heart, often caused by congenital heart defects.) Finally, by injecting dye through the catheter while a series of rapid x-ray images is recorded, "movies" can be made of the blood flowing through the cardiac chambers, or the through the blood vessels surrounding the heart - a procedure know as angiography (also called arteriography).
Once the procedure is completed, the catheter(s) are removed. Bleeding is controlled by placing pressure on the catheterization site for 30 - 60 minutes.
What kinds of heart disease can catheterization and angiography help to evaluate?
Cardiac catheterization and angiography can reveal vital information about overall cardiac function, about the function of the individual cardiac chambers, about the cardiac valves (whether they are too narrow (stenosis) or too leaky (regurgitation)), congenital heart defects, and about the location and severity of blockages in the coronary arteries (the arteries that supply blood to the heart muscle).
What are some of the variations used with catheterization and angiography?
Cardiac catheterization is often used therapeutically, that is, to deliver treatment for various heart problems. Therapeutic catheterizations include procedures to dilate narrowed heart valves, procedures to close atrial septal defects (i.e., a hole in the wall separating the left and right atria), and of course, procedures to relieve blockages in the coronary arteries (angioplasty and stent placement).
What are the risks of having a catheterization or angiography?
Cardiac catheterization and angiography are relatively safe, but because they are invasive procedures involving the heart, several complications are possible. Nobody should have a cardiac catheterization unless there is a reasonable likelihood that the information gained from the procedure will be of significant benefit.
Minor complications of cardiac catheterization include minor bleeding at the site of catheter insertion, temporary heart rhythm disturbances caused by the catheter irritating the heart muscle, and temporary changes in the blood pressure.
More significant complications include perforation of the heart wall (causing a life-threatening condition called cardiac tamponade), sudden blockage of a coronary artery (leading to a heart attack), extensive bleeding, stroke, or an allergic reaction to the dye used in angiography.
