What is Heart Disease?
Heart disease refers to a variety of heart disease and cardiovascular system disorders. The most common type of heart disease is coronary heart disease (CHD), also known as coronary artery disease.
The cardiovascular system (CV) is the heart, blood vessels and blood circulatory system responsible for the transport of oxygen and nutrients and waste products through the body.
The pumping heart supplies the energy that enables blood to circulate through the vascular system.
Coronary Heart Disease (Coronary Artery Disease)
The arteries that supply the heart with blood are called coronary arteries; they are on the heart’s surface. Three major coronary arteries are located on the right and two on the left.
Coronary heart disease occurs when your coronary arteries are narrowed and hardened by cholesterol and other substances in the blood vessel’s inner lining, a process known as atherosclerosis. When this happens, the supply of blood and oxygen to the heart muscle is limited, especially during exercise, which leads to pain or discomfort in the chest area known as Angina or even heart attack.
Angina: If the coronary arteries are partially blocked, chest pain may occur.
Heart Attack: The patient will have a myocardial infarction when the coronary arteries are completely blocked. A heart attack is the most common cause of heart failure.
Smoking, high cholesterol, hypertension, diabetes and inadequate physical activity are other risk factors for coronary heart
Protect your heart by adapting to a healthier lifestyle, including stopping smoking; changing to a low cholesterol diet, lower saturated fats and high dietary fiber; reducing salt intake; exercising more and meditating.
