Coronary artery disease (CAD) remains the leading cause of death in the United States. CAD is hardening and narrowing of the coronary arteries wrap around the heart. The most common cause of death in women over 50 is DAC and not cancer. The same goes for men.
Your heart is about the size of a fist. This organ is located behind the breastbone in the center of your chest, between the right and left lung.
Coronary arteries are the arteries located on the surface of the heart – that supply oxygen and nutrients to the heart muscle to work effectively.
The right coronary artery feeds the right and bottom side of the heart. The left anterior descending feeds the front left and the circumflex artery supplies the back of the heart.
CAD is usually caused by atherosclerotic plaques on the inner walls of the arteries. These plaques can restrict blood flow to the heart muscle due to obstruction of the artery. Without an adequate supply of blood, the heart muscle becomes starved of oxygen and vital nutrients to function properly.
CAD can be noticeable for several years and can lead to chest pains called angina chest. If the blood supply to part of the heart muscle is cut completely a heart attack can occur. Other symptoms such as difficulty breathing, nausea, dizziness, palpitations, fatigue or weakness (equivalent angina) may occur.
An estimated 15.4 million American adults have CAD. Of these, 7.8 million have angina pectoris (AP) and 7.6 million have a myocardial infarction (heart attack) myocardial. (Heart disease and stroke statistics -2014 Update).There are more than 500,000 new cases of angina every year. Angina significantly limits impairs the functional ability and quality of life.
