• What is Heart Disease?

  Date: 2007.12.09 | Category: Heart Tips | Response: 0

  Cardiovascular disease is a very broad term. Cardiovascular disease refers to diseases of the heart (cardio) and diseases of the blood vessels (vascular), hence cardio-vascular disease. However, diseases affecting the heart are referred to as heart disease.

  The term heart disease is a very broad term. Problems can arise within the heart muscle, arteries supplying blood to the heart muscle, or the valves within the heart that pump blood in the correct direction. Understanding the differences between each disease of the heart can help with the confusing applications of the term heart disease. Coronary artery disease or CAD is the most common type of heart disease and the leading cause of death in both genders in the U.S. Coronary artery disease affects the arteries supplying blood to the heart muscle. These coronary arteries harden and narrow due to the buildup of a waxy cholesterol, fatty substance referred to as plaque.

  This plaque buildup is known as atherosclerosis. The increase in plaque buildup causes the coronary arteries to become narrower. This will cause blood flow to become restricted, decreasing the amount of oxygen delivered to the heart muscle. Decreasing the amount of oxygen supplied to the heart muscle can cause angina (chest pain) and lead to a heart attack. Coronary artery disease over time can weaken the heart muscle contributing to heart failure and arrhythmias (abnormal heart rhythms).

  Coronary heart disease is another confusing type of heart disease. Coronary heart disease is not the same thing as coronary artery disease. While coronary artery disease refers to the coronary arteries, coronary heart disease refers to the diseases of the coronary arteries and resulting complications. This includes such complications such as chest pain, a heart attack, and the scar tissue caused by the heart attack. Understanding this subtle difference between the two may impress your cardiologist.

  Cardiomyopathy is a disease affecting the muscle of the heart. Cardiomyopathy can be genetic or caused by a viral infection. Cardiomyopathy can be classified as primary or secondary. Primary cardiomyopathy is attributed to a specific cause (hypertension, congenital heart defects, heart valve disease). Secondary cardiomyopathy is attributed to specific causes (diseases affecting other organs).

  There are three main types of cardiomyopathy. Dilated cardiomyopathy is enlargement and stretching of the cardiac muscle. Hypertrophic cardiomyopathy causes thickening of the heart muscle. Restrictive cardiomyopathy causes the ventricles of the heart to become excessively rigid causing blood flow to the ventricles to be difficult between heartbeats.

  Valvular heart disease is a disease that affects the valves of the heart. Valves within the heart keep the blood flowing in the correct direction. Damage to valves can be caused by a variety of conditions leading to regurgitation or insufficiency (leaking valve), prolapse (improper closing of the valve), or stenosis (narrowing of the valve). Valvular heart disease can be genetic. Valvular heart disease can also be caused by certain infections such as rheumatic fever, and certain medications or radiation treatments for cancer.

  The pericardium is a sac that encompasses the heart. Pericardial disease is inflammation (pericarditis), stiffness (constrictive pericarditis), or fluid accumulation (pericardial effusion) of the pericardium. Pericardial disease can be caused by many things such as occurring after a heart attack.

  Congenital heart disease is a form of heart disease that develops before birth. Congenital heart disease is an extremely broad term. However, these diseases usually affect the formation of the heart muscle, chambers, or valves. A few examples include coarctation or a narrowing of a section of the aorta; atrial or ventricular septal defect is referred to as holes in the heart. Congenital heart disease should be classified more accurately as an inborn defect that occurs in around 1% of births. Congenital heart disease may be inherited (heredity), or caused by certain infections such as German measles contracted while pregnant. However, researchers are currently studying factors that may cause congenital heart disease.

  Heart failure is another type of heart disease characterized by the hearts inability to effectively pump enough blood to the bodys organs and tissues. When the bodys vital organs do not receive enough blood flow certain signs and symptoms can occur such as shortness of breath, fatigue, and fluid retention. Congestive heart failure is a type of heart failure that leads to fluid buildup in the body. It is important to note that not all heart failure is congestive. Heart failure may result from other cardiovascular diseases such as cardiomyopathy or coronary heart disease. Heart failure may come on suddenly or develop over many years.

  The month of February is the National Heart Disease awareness month. However, heart disease awareness should be each and every day. With staggering statistics, awareness begins with understanding the different types of heart disease. A diet and lifestyle that is conducive to heart health can mean the difference between life and being a statistic.

• Women’s Heart Health

  Date: 2007.07.17 | Category: Heart Tips | Response: 0

  Most women know that heart disease is the number-one killer in the United States–of men. Most women also realize the value of eating healthy food, exercising, and decreasing stress–for their families and loved ones. Information is abundant and readily available in books, newspapers and magazines, and on television and radio about the risk of cardiovascular disease in men.

  But the widespread belief that heart disease is exclusively a man’s problem is a myth. Women–and most physicians–are not aware that cardiovascular disease is the number one-killer of women as well as men. The facts speak for themselves: Of the 520,000 people who die of heart attacks in the United States each year, almost half–about 250,000–are women In addition, almost 100,000 women die of strokes. Substantially fewer women die annually from breast cancer (40,500) or lung cancer (41,500). Overall, heart and vascular diseases claim more American women’s lives than do all forms of cancer combined.

  Moreover, many of the factors that determine the risk of heart disease for women differ from those for men. Dr. William Castelli, a leading authority on heart disease and director of the Framingham Heart Study, which has done research on heart disease risk factors for forty years, has referred to these unique risks for women as a “whole new syndrome” associated with a “galloping progression of atherosclerosis.

  Women are largely unaware of the effects of estrogen, birth control pills, and cigarettes and few know that if they smoke and take birth control pills, they have about forty times more chance of heart disease than women who do not. Women above age thirty-five are particularly at risk. It is vital to understand the factors favoring heart disease, because they may be avoidable or modifiable. In fact, according to Dr. Dean Ornish, women may have to do less than men to affect their outlook positively. In a study he conducted evaluating the effect of life-style changes in reversing heart disease, women responded better than men, even when women did less to restrict their diets, exercise, or reduce stress. By understanding their risks and ways to minimize them, women can lessen the chances of being victims of what the American Heart Association has called “the silent epidemic.”

  The purpose of developing and maintaining a healthy way of life for yourself as a woman is not only to decrease the risk of heart disease but also to fell well and feel good. Physical activity does not have to be strenuous to be beneficial. More women than ever are discovering that exercise in moderation is exhilirating. Healthy changes in eating do not have to be unduly restrictive. The food you eat can continue to be delicious and satisfying. By using simply new tools to maintain a healthy weight, you will decrease the chances of developing three big heart disease risks–diabetes, high blood pressure and high cholesterol–and discover a renewed sense of self at the same time.

  By taking control of your health, you will be more able to take control of other aspects of your life. In so doing, you will achieve a greater sense of well-being, which is the true meaning of health. This is a marvelous opportunity for you personally. In addition, your new healthy living habits can be a model for family and friends. You thus may make a significant difference in their lives and health as well as your own. In the words of Hillel: “If I am not for myself, then who will be for me? If not now, when?”

• Facts about Heart Fluttering

  Date: 2007.07.07 | Category: Heart Tips | Response: 0

  07/07/07 – Almost a James Bond Day

  Heart fluttering is a condition that most people have experienced at some time or another. It is the sensation of a heart beating too much swiftly or irregularly. Heart fluttering is usually called “palpitations,” which are rapid, forceful, regular or irregular heartbeats that are quite noticeable to the individual. A rapid, regular heart fluttering may be associated with sensation of pounding in the neck as well, due to simultaneous contraction of the upper, priming chambers of the heart which is the atria and the lower, main pumping chambers called the ventricles. If the heart fluttering feels very irregular, then it is likely that the underlying rhythm is atrial fibrillation. During this type of rhythm abnormality, the atria beat so rapidly and irregularly that they seem to be quivering, rather than contracting. The ventricles are activated more rapidly than normal and in a very irregular pattern.

  Heart fluttering occurs normally during an exertion or an emotion, but some people can have an increase or irregularities of heart rate without warning and without an apparent reason. This generates the sensation of heart fluttering which is due in the majority of cases to an impairment of cardiac rhythm o arrhythmia. Heart fluttering may also be associated with feelings of anxiety or panic; it is normal to feel the heart thumping when you are terrified of something If heart fluttering is short-lasting there is no problem for the child, but if it last more than half an hour, it is advisable to call on a physician or a hospital to make an examination and an ECG.

  While heart fluttering can be a cause of concern to people who experience them, it is usually not a sign of an impending heart attack. For most people who are physically healthy and emotionally well-adjusted, they do not signify an underlying heart disorder but are most commonly caused by physical exertion, anxiety, fear, excessive smoking, too much caffeine, and ingredients in certain medications, including some cough and cold medications. In rare cases, heart fluttering is a long-standing accompaniment to an underlying severe anxiety disorder.

  Heart fluttering can also be caused by actual heart disease. This can be distinguished by its particular pattern, depending on how heavy and regular the beating is. A cardiologist may be able to make a diagnosis based on the pattern, or may order an electrocardiogram for more precise information. When symptoms such as sweating, faintness, and chest pain occur with the heart fluttering, it is best to consult a cardiologist. As soon as the heart fluttering cause is determined, most people are able to live and deal with it and would not even notice.

  Generally heart fluttering is not dangerous, even if it can provoke anguish, because it is unpleasant to feel the proper heart beating swiftly without reason. If extra beats are enough of a problem to warrant treatment, then usually a beta-blocking drug will be used. These block the effect of adrenaline on the heart, and are also used for the treatment of angina and high blood pressure. However, they can cause increased tiredness, sleep disturbance, depression, impotence, and can aggravate asthma. Other anti-arrhythmic drugs can be used if beta-blockers are not appropriate, but they too have potential side effects.

  Heart fluttering which can already cause blackouts or near blackouts should be taken seriously. Even if ultimately nothing untoward is found you should contact your doctor as soon as possible to arrange the appropriate investigations if heart fluttering is associated with blackouts.
