4. Do you believe that there is currently enough public education on the topic of cardiovascular disease? In your lifetime, do you feel like you have been exposed to enough educational material to know what the risks are in your own life?
1 The term "heart disease" is often used interchangeably with the term "cardiovascular disease." Cardiovascular disease generally refers to conditions that involve narrowed or blocked blood vessels that can lead to a heart attack, chest pain (angina) or stroke. Other heart conditions, such as those that affect your heart's muscle, valves or rhythm, also are considered forms of heart disease
While cardiovascular disease can refer to different heart or blood vessel problems, the term is often used to mean damage to your heart or blood vessels by atherosclerosis (ath-ur-o-skluh-ROE-sis), a buildup of fatty plaques in your arteries. Plaque buildup thickens and stiffens artery walls, which can inhibit blood flow through your arteries to your organs and tissues.
Atherosclerosis is also the most common cause of cardiovascular disease. It can be caused by correctable problems, such as an unhealthy diet, lack of exercise, being overweight and smoking.The tests you'll need to diagnose your heart disease depend on what condition your doctor thinks you might have. No matter what type of heart disease you have, your doctor will likely perform a physical exam and ask about your personal and family medical history before doing any tests. Besides blood tests and a chest X-ray, tests to diagnose heart disease can include:electrocardiogram, holter monitering, echo cardiogram, stress test, cardiocatheterization, ct scan, cardiac mangnetic resonance imanging
Heart disease treatments vary by condition. For instance, if you have a heart infection, you'll likely be given antibiotics. In general, treatment for heart disease usually includes:
2 Heart disease is the leading killer of men and women—and claims more lives than all forms of cancer combined. Being diagnosed with cardiovascular disease can also take an emotional toll, affecting your mood, outlook, and quality of life. While weight control and regular exercise are critical for keeping your heart in shape—the food you eat can matter just as much. In fact, along with other healthy lifestyle choices, a heart-healthy diet may reduce your risk of heart disease or stroke by 80%. By adopting better eating habits, you may be able to lower cholesterol, prevent or manage heart disease and high blood pressure, and take greater control over the quality and length of your life
Coupled with regular exercise, a heart-healthy diet can help you to lower cholesterol, control your blood pressure and blood sugar levels, and maintain a healthy weight—while simultaneously improving your mood and outlook. No single food can make you magically healthy, so your overall dietary pattern is more important than specific foods. Instead of fried, processed food, packaged meals, and sugary snacks, a heart-healthy diet is built around “real,” natural food—fresh from the ground, ocean, or farm.
Whether you’re looking to improve your cardiovascular health, have already been diagnosed with heart disease, or have high cholesterol or high blood pressure, these heart-healthy diet tips can help you better manage these conditions and lower your risk of a heart attack.

Eat more: | Eat less: |
Healthy fats, such as raw nuts, olive oil, fish oils, flaxseeds, and avocados | Trans fats from partially hydrogenated or deep-fried foods; saturated fats from fried food, fast food, and snack foods. |
Colorful fruits and vegetables—fresh or frozen | Packaged foods, especially those high in sodium and sugar |
High-fiber cereals, breads, and pasta made from whole grains or legumes | White or egg breads, sugary cereals, refined pastas or rice |
High-quality protein, such as fish and poultry | Processed meat such as bacon, sausage, and salami, and fried chicken |
Organic dairy such as eggs, skim milk, or unsweetened yogurt | Yogurt with added sugar; processed cheese |
Three keys to a heart-healthy diet
1. Be smart about fats
If you are concerned about your heart health, rather than avoiding fat in your diet, try replacing unhealthy fats with good fats. Some of the most important improvements you can make to your diet are to:
Cut out trans fats. As well as raising your LDL, or “bad” cholesterol level, which can increase your risk for heart attack and stroke, trans fat also lowers your levels of HDL or “good” cholesterol, which can put you at increased cardiovascular risk. Trans fats are found in foods such as commercially-baked goods, fried food, and anything with “partially hydrogenated” oil in the ingredients, even if it claims to be “trans fat-free.”
Limit saturated fats. Saturated fats are mainly found in tropical oils, dairy, and red meat and should be limited to no more than 10% of your daily calorie intake. Enjoy dairy in moderation and vary the protein sources in your diet, opting for fish, skinless chicken, eggs, and vegetarian sources of protein where you can.
Eat more healthy fats. Eating foods rich in monounsaturated and polyunsaturated fat can improve blood cholesterol levels and lower your risk of heart disease. Eat omega 3 fatty acids every day, from fatty fish such as salmon, trout, or herring, or from flaxseed, kale, spinach, or walnuts. Other sources of healthy fats include olive oil, avocados, nuts, and nut butters.
2. Don’t replace fat with sugar or refined carbs
When cutting back on heart-risky foods, such unhealthy fats, it’s important to replace them with healthy alternatives. Replacing processed meats with fish or chicken, for example, can make a positive difference to your health. But switching animal fats for refined carbohydrates, though—such as replacing your breakfast bacon with a donut or sugary cereal—won’t do anything to lower your risk for cardiovascular disease.
Your body doesn’t need any added sugar—it gets all it needs from the sugar that naturally occurs in food. Sugary food and refined carbs just add up to a lot of empty calories that are as bad for your heart as they are for your waistline.
Instead of sugary soft drinks, white bread, pasta and processed foods like pizza, opt for unrefined whole grains like whole wheat or multigrain bread, brown rice, barley, quinoa, bran cereal, oatmeal, and non-starchy vegetables.
3. Focus on high-fiber food
A diet high in fiber can lower “bad” cholesterol and provide nutrients that help protect against heart disease. As an added bonus, it may also help you to lose weight. Since fiber stays in the stomach longer than other foods, the feeling of fullness will stay with you much longer, helping you eat less. Fiber also moves fat through your digestive system quicker so less of it is absorbed. And when you fill up on fiber, you’ll also have more energy for exercising.
Insoluble fiber is found in whole grains, wheat cereals, and vegetables such as carrots, celery, and tomatoes.
Soluble fiber sources include barley, oatmeal, beans, nuts, and fruits such as apples, berries, citrus fruits, and pears.
Steer clear of salt and processed foods
Eating a lot of salt can contribute to high blood pressure, which is a major risk factor for cardiovascular disease. The American Heart Association recommends no more than a teaspoon of salt a day for an adult. That may sound alarmingly small, but there are actually many painless—even delicious—ways to reduce your sodium intake.
Reduce canned or processed foods. Much of the salt you eat comes from canned or processed foods like soups or frozen dinners—even poultry or other meats often have salt added during processing. Eating fresh foods, looking for unsalted meats, and making your own soups or stews can dramatically reduce your sodium intake.
Use spices for flavor. Cooking for yourself enables you to have more control over your salt intake. Make use of the many delicious alternatives to salt. Try fresh herbs like basil, thyme, or chives. In the dried spices aisle, you can find alternatives such as allspice, bay leaves, or cumin to flavor your meal without sodium.
Substitute reduced sodium versions, or salt substitutes. Choose your condiments and packaged foods carefully, looking for foods labeled sodium free, low sodium, or unsalted. Better yet, use fresh ingredients and cook without salt.
