Heart Disease describes a variety of disorders and conditions that can affect the body's pumping machine. The most common type of heart disease is coronary heart disease (CHD), which is also as Coronary Artery Disease.
The following disorders may be cause to affect your heart
Coronary arteries supply the heart muscles with oxygen and nutrients. In Coronary Heart Disease, the coronary arteries that supply blood to the heart become narrow. This happens because cholesterol and other substances build up in the wall of the blood vessel, affecting blood flow to the heart muscle.
Deposits of cholesterol and other fat-like substances thicken the inner lining of the blood vessels, which forms a bump called plaque in the blood vessel wall. Plaque build up narrows and hardens the blood vessel, and this process is called atherosclerosis (hardening of the arteries). Plaque eventually reduces or blocks blood flow to the heart.
Angina: In angina, the heart muscles does not receive enough oxygen and nutrients. In angina, a feeling of discomfort or pressure in the chest, ranging from a vague ache to a crushing sensation and pain or pressure in the left arm, shoulder, or throat, and difficulty catching your breath.
Heart failure: This occurs when a weakened heart cannot pump efficiently. This results in build up of fluids in the ankles, legs, lungs and other tissues. The combination of clogged blood vessels and high blood pressure often causes heart failure.
Heart attack: When blood flow to any part of the heart is blocked completely, the cells in that part of the heart begin to die. This causes a heart attack. This usually happens when a narrowed coronary artery is suddenly blocked. The symptoms of the heart attack may vary widely for each person but can include the following:
