Coronary artery disease (CAD) results when our body’s coronary arteries become damaged. Our coronary arteries are important because “they supply our heart with blood, oxygen, and nutrients” (Coronary artery disease, 2014). Our arteries typically get damaged because of plaque and inflammation developing inside them. “The buildup of plaque causes our arteries to become narrower and that decreases our blood flow to our heart” (Coronary artery disease, 2014). This decreased blood flow can cause…

Coronary artery disease (CAD) is a narrowing of the small blood vessels that supply blood and oxygen to the heart. Coronary artery disease (CAD) is the leading cause of death worldwide. While the symptoms and signs of coronary artery disease are noted in the advanced state of disease, most individuals with coronary artery disease show no evidence of disease for decades as the disease progresses before the first onset of symptoms, often a "sudden" heart attack, finally arises (Gaziano et al.,…

Coronary Artery disease is a cardiovascular disease that develops from excessive plaque buildup in the arteries, which obstruct blood flow and increase the risk for heart attack and stroke. This disease can be heredity but may also develop as one gets older. The numbers of deaths reported yearly from this disease are quite high. There are many obvious symptoms and risk factors associated with this disease that one should never ignore. There are numerous amounts of measures one may take in order…

getting enough rest, which they are correct. Some people do not do that and they have a higher risk of developing heart diseases. When that happens many have to undergo a Coronary Artery Bypass Surgery. A Coronary Artery Bypass is when the unhealthy secretions of your coronary arteries are bypassed with strong artery or vein grafts to increase blood flow to the heart…

the superior thyroid artery and its relation to the external laryngeal nerve. Introduction The thyroid gland is the largest endocrine gland located in the anterior triangle of the neck. It consists of two lobes, right and left, connected by an isthmus in the middle. The thyroid gland is mainly supplied by the superior thyroid artery, the first branch of the external carotid artery, and the inferior thyroid artery, a branch of the thyrocervical trunk of the subclavian artery; and occasionally by…

Introduction Coronary artery bypass surgery (CABG) is becoming a common practice in our society with approximately 469,000 procedures occurring each year (Pick, 2008). Recovering from this surgery not only entails a long physical recovery, but it can also have an emotional effect on the patient. The emotional well-being of the patient can have a negative consequence on the recovery of the patient. Added stress and depression after the surgery could lead to a complicated recovery and possible…

ARTERIES The walls of arteries contain flat and smooth muscle fibre that deal and relax under the guidelines of the sympathetic nervous system. The functions of the arteries are: transport blood away from the heart and transport oxygenated blood only. Arteries have four different parts, which are lumen, endothelium, smooth muscle and connective tissue. In arteries, the function of the lumen is to fires blood into the arteries at a high pressure, and they are very thick. The endothelium is made…

The Coronary Arteries The main branches of the aorta are supply routes to the heart muscle itself. There are two fundamental coronary corridors: the left principle (LM) and right coronary veins (RCA). The left primary coronary supply route separates into two fundamental branches: the left foremost diving (LAD), which keeps running down the front of the heart, and the circumflex course (CX) which keeps running behind the heart. Branches of the LAD are called corner to corner conduits and…

that are associated with coronary circulation are the right coronary artery and the left coronary artery. These two major arteries bifurcate off of the Aorta and encircle the heart ultimately meeting at the coronary sinus. The left main coronary artery which runs across the left side of the heart and passes between the pulmonary trunk and left auricle gives origin to two smaller coronary arteries: the anterior interventricular artery (Also…

wave velocity (PWV) increases more with age than the carotid-radial PWV. This is due to the reduction of elasticity in central arteries; the PWV of these arteries is included in the carotid-toe measurement but not the carotid-radial measurement. First of all, the propagative model of the circulatory system is used when examining PWV. This model consists of distensible arteries that end with resistance vessels, whose distributed elastic properties allow the generation of a pressure wave that…
