Coronary Heart Disease Causes Coronary heart disease is caused by some obstructions in the coronary arteries that prevent the heart from receiving ample amount of oxygen and nutrition-rich blood. The most common cause of this condition by far is atherosclerosis. Lack of sufficient blood is known as ischemia; therefore coronary heart disease is at times known as ischemic heart disease as well. The cause of the coronary heart disease is connected to many risk factors of which the following are most common: Heredity: If coronary heart disease runs in family. High cholesterol: Levels of cholesterol in the blood are over-healthy levels. This generally involves higher level of low-density lipoprotein (also called LDL), bad cholesterol, as well as low levels of high-density lipoprotein (also called HDL), good cholesterol. Tobacco abuse: This comprises not just smoking any type of tobacco (pipes, cigarettes and cigars), however also chewing tobacco. Diabetes Obesity High blood pressure (hypertension) Lack of regular work-out Emotional stress High-fat diet Type A personality (competitive, impatient, aggressive) Coronary Heart Disease (CHD) is the disease of coronary artery, a state whereby the artery that supplies blood to the heart is blocked or clogged, decreasing the blood flow to the heart muscles that require oxygen from the blood supply and this might lead to complete artery blockage. When this takes place in the heart, the outcome is a heart attack medically recognized as myocardial infarction. This procedure when strikes it the blood vessels supplying blood to the brain results in a stroke. Coronary Heart Disease is caused mostly due to formation of plaques (or fatty deposits) in the lining of arteries and ruptures to this plaque. This plaque decrease the size of the arteries resulting in less blood flow through them, thus depriving the heart muscles of the much required oxygen. If the blood supply is not restored, there would be a lasting heart injury. Due to our western lifestyle particularly in our eating habits, the health of arteries slowly deteriorates when we grow older. Cholesterol and fats becomes the main reason for clogging of the arteries. The fatty deposits (or plaques) in the arteries are medically known as atheroma and the entire procedure is called atherosclerosis. The more the plaques or fatty deposits, the larger the danger of heart attacks. Women must be more cautious, since a woman's heart is smaller and they also have narrower coronary arteries as compared to that of men; therefore it takes less pestilence to block them. Thrombosis and plaque rupture leads to a total blockage of the artery. When these plaques shatter, it releases an intricate chemical that triggers innumerable events resulting in thrombosis. The most familiar symptom of CHD is the Angina Pectoris (or chest pain). Angina takes place as the outcome of restriction of flow of blood to the heart because of plaque formation in the coronary arteries. The ache is described as the crushing or a gripping pain across the chest that might also radiate into the throat or teeth and followed by breathlessness and sweating. Stroke and CHD are the two most common types of cardiovascular illness. They account for around 75% of all deaths connected to heart diseases. |
