Numerical simulation of the blood flow through a pre-stenotic aneurysm in coronary artery: effects of varying heart rate.

The left anterior descending artery (LAD) is a significant coronary artery and a facilitator of oxygenated blood to the heart muscles. Thus, any occurrence of an aneurysm in LAD requires immediate medical attention. It is often inclined toward fatality if coupled with a blockage due to stenosis.
