The right coronary artery arises from the right coronary cusp and is the dominant coronary vessel in 80% of individuals (dominance refers to the coronary vessel that supplies the posterior ...

The left coronary artery continues at the anterior side of the heart between the right and left ventricle. Several diagonal branches cross the left ventricular anterior wall (Figure 2).

The heart muscle needs oxygen-rich blood to do its job. The vessels that feed the heart are called coronary arteries (shown in the diagram right) and they branch off from the body’s main artery, the ...

For an estimated 80% of humans, that artery comes from the right main coronary artery, but for about 10%, it comes from the left. In another 10%, there are two of these arteries of roughly equal ...

A 65-y-old woman with multiple cardiovascular risk factors presented with atypical chest pain, prompting a 1-d pharmacologic stress myocardial perfusion test using 99mTc sestamibi. Initial ...

During a coronary artery bypass, the diseased sections of your coronary arteries are bypassed with healthy artery or vein grafts to increase blood flow to the heart muscle tissue. This procedure is ...

A coronary artery calcium score of zero indicates essentially no advanced coronary plaques. A score of 1-99 indicates a mild case of plaque, a score of 100-299 a moderate case, and a score of 300 ...

As plaque (cholesterol deposits) builds up in coronary arteries, calcium is also deposited. A low-dose CT scan can measure the amount of calcium. Ideally, you would have a score of 0, and the higher ...

BACKGROUND: High-volume physical activity (PA) is associated with a higher prevalence of subclinical coronary artery disease (CAD). However, the clinical significance of subclinical CAD among ...
