Heart Disease
Heart disease is an abnormal condition of the heart and the heart circulation. It is also known as cardiovascular disease which is our nation's number one killer. The coronary arteries supply the heart with oxygen-rich blood. When the arteries narrow, less blood and oxygen flow to the heart. This is called coronary artery disease. Lack of oxygen to the heart can cause angina or a heart attack. Most cases of coronary artery disease are due to atherosclerosis... which is the hardening of the arteries in which fatty deposits build up inside the coronary arteries, restricting blood flow.Heart disease is the most common, and most preventable heart disease of all coronary artery diseases. One of the most common symptoms is chest pain. When your heart muscle's not getting enough oxygen, it sends out a painful warning signal called angina pectoris and because your heart needs oxygen the most when it is working the hardest, angina is most likely to occur during when you're exercising. If the heart muscle is la
cking oxygen for long enough, it will die - resulting in a heart attack. You should try to control the risk factors, such as cholesterol, high blood-pressure, stress control, smoking habits, lack of exercise, and dietary problems. Classic angina is caused by exertion, stress, or exposure to cold and is relieved by rest or nitroglycerin. The most widely used screening test is the stress test. The EKG - electrocardiogram, is a test that measures the heart's electrical activity. Sometimes there can be shortness of breath, fatigue, or rapid beating instead of pain. Blood pressure screening can detect hypertension before it causes any damage but in coronary artery disease, screening is more complex and less effective. Preventing this disease should be a # 1 priority. Anything that increases oxygen demand can cause angina, including exercise, cold weather, emotional tension, and even large meals. or myocardial infarction which means "heart muscle tissue death". The typical symptoms are chest pains - that can be mild, moderate, or severe (but it's described as a heavy pressure that can resemble a crushing object over the chest). Angina isn't a disease by itself but it's the primary symptom of coronary artery disease. There is no one way, to control these factors, but common sense and modern medicine tells us how to.
