What is Coronary Artery Disease?

Coronary artery disease is a type of heart disease that develops when the arteries of the heart cannot deliver enough oxygen-rich blood to the heart. It is the leading cause of death in the United States. Coronary heart disease is often caused by the buildup of plaque, a hard substance, inside the lining of larger coronary arteries. This buildup can partially or totally block blood flow in the large arteries of the heart.

People with a history of high cholesterol, diabetes, smoking, high blood pressure, being overweight, or a family history of heart disease are at higher risk of developing CAD. Menopause may also increase the risk of CAD in women. Reduced blood flow means less oxygen is getting to the heart. This may cause mild to severe chest pains or pressure, called angina, which can spread to the arms or jaw.

What is a coronary stent?

Coronary stents are wire, mesh tubes that help widen a narrowed segment of an artery and restore adequate blood flow to the heart muscle. The coronary stents come in different sizes and length to appropriately fit the vessel. The stent will stay in place permanently to help keep open the artery and decrease its chance of narrowing again. Over time, the inner lining of the artery will grow over the surface of the stent, making it a permanent part of your artery.

Placing angioplasty stents is a common procedure for people experiencing a heart attack, and for those who have not had a heart attack but whose coronary arteries appear narrowed on imaging tests.

The main advantage of cardiac stents is that it can immediately restore oxygen flow to the heart muscle sparing further tissue damage. This is crucial in heart attack patients as because it can save life or prevent further sequela. Compared to its alternative which is open heart surgery, cardiac stents allow for faster recovery times, less pain, fewer complications and no need for general anesthesia.,

AtlasTM is a coronary balloon expandable stent system consisting of Everolimus particle. It is indicated for de novo and in-stent restenotic lesions in patients with coronary artery disease – including acute coronary syndrome acute myocardial infarction or unstable angina and/or concomitant diabetes mellitus – to improve luminal diameter and reduce restenosis within the stent and at the stent edges in native coronary arteries, de novo chronic total coronary occlusions and improving coronary artery luminal diameter in patients. Stent system is indicated reference vessel diameters of ≥ 2.25 mm to ≤ 4.25 mm and a lesion length of ≤ 27 mm.
