coronary heart disease information
Coronary Heart Disease (CHD), also known as coronary heart disease, affects approximately 14 million men and women in the United States. Disease arises when a combination of fatty material substances, calcium and scar tissue (plaque) builds in the arteries provide that the heart with blood. Through these arteries, called coronary arteries, the heart muscle (myocardium), the oxygen and other nutrients needed to pump blood.
Coronary heart disease (CHD) is a preventable disease that kills more than 110,000 people each year in England. More than 1.4 million people suffer from angina and 275,000 people a year a heart attack. CHD is the commonest cause of death in the country.The government is committed to reducing the mortality rate from cardiovascular disease and stroke, and diseases for people under 75 by at least 40% (to 83.8 deaths per 100,000 population) from 2010.
A heart attack occurs when blood flow to an area of heart muscle is completely blocked. This prevents oxygen-rich blood from reaching that area of heart muscle and leads them to die. Without prompt treatment, a heart attack can lead to serious problems and even death. Over time, CAD can weaken the heart muscle and leads to heart failure and arrhythmias (ah-Rith-me-AHS). Heart failure is a condition in which your heart can not pump enough blood through the body. Arrhythmias are problems with the speed and rhythm of the heartbeat.
It is usually caused by a so-called atherosclerosis, which occurs when fatty acids and a substance called plaque builds on the walls of the arteries. This means that they are close. Since the coronary arteries narrow, blood flow in the heart can slow or stop, causing chest pain (stable angina), shortness of breath, heart attack and other symptoms. Coronary heart disease (CHD) is the leading cause of death in the United States of men and women. According to the American Heart Association, more than 15 million people are in some form on the state.
Coronary artery disease occurs when the coronary arteries (the arteries that supply blood and oxygen to the heart muscle) decreased by a gradual building of fatty materials within their walls material. This condition is called atherosclerosis and the fatty material is called atheroma. Over time, the artery may be so narrow that it is not enough oxygen to the heart muscle with blood, especially at times when there is more demand-such as when you exert yourself. The pain or discomfort, as a result of what is called angina.
If a coronary artery is completely blocked, you may have a heart attack. The classic symptoms of a heart attack are pain in the crushing chest pain in the shoulder or arm, and shortness of breath. Women are slightly more likely than men to other warning signs of a heart attack, including nausea and back or jaw pain. Sometimes a heart attack occurs, without any visible signs or symptoms.
Many of the plaque deposits are hard on the outside and soft and mushy on the inside. The hard surface can crack or break, allowing the soft, fatty inside. If this happens, platelets (disc-shaped particles in the blood that aid clotting) come to the area, and blood clots form around the plaque. This causes the artery to narrow even more.
The symptoms of CAD 1) chest pain (angina pectoris) from inadequate blood flow in the heart, 2) heart attack (acute myocardial infarction), from the sudden blockage of the coronary, or 3) sudden death through a lethal rhythm disturbances .
