These occur because of hemodynamic compromise, embolization, or thrombosis (Greelish, Mohler, Fairman, 2009). The review by Greelish, (2009), includes major trails which evaluate the efficiency as well as clinical variables and risk. There are two major trials discussed in this paper, those are the North American Symptomatic Carotid Endarterectomy Trial and the European Carotid Surgery Trial. Each of these demonstrate the efficacy of the carotid endarterectomy in patients who have symptoms such as transcient ischemic attack (Greenlish, et.al, 2009).
The NASCET cohort is another study done that suggests the benefits of CEA in symptomatic patients may be overestimated, since a number of strokes that occur in the territory of stenotic arteries are not preventable by CEA. 1800 patients were included in this study which was done to assure that we knew what the true risk factors of this group of patients with stroke might be. This study showed that that stroke occurred most often in people that had 60% stenosis. This is well supported in all of the studies that were reviewed. Patients with 60% occlusion whether symptomatic or asymptomatic are at great risk.
Risk factors lead to damage in the carotid arteries and th...
Secondary prevention of stroke: risk factor reduction by Furie, Wilterdink and Kistler, (2009) review risk factor management of patients with atherosclerotic cerebrovascular disease, with a focus on secondary prevention in patients who have had ischemic attack or ischemic stroke. Those risk factors that are discussed in great depth in this paper are hypertension, smoking, diabetes, metabolic syndrome, and dyslipidemia. They show statistical data on those patients that control these risk factors and those that don't as well as how the CEA fits into this care (Furie, et. al., 2009). CEA alone will not forever cure a patient with large number of risk factors. The patient has to be willing to participate in this care, also.
Cardiovascular disease, MI or ischemic stroke is still the leading cause of death in patients with metabolic syndrome and diabetes. Haffey, (2009), suggests success in saving lives here is based on effectively treating the whole patient. The author describes throughout his paper, different clinical approaches to achieving this goal. He reminds that treating those things that are risk factors for the disease should be dealt with aggressively. Those include hypertension, smoking, activity levels, dietary habits, obesity, carotid artery stenosis, and atrial fibrillation (Haggey, 2009). Again, as in the previous literature, Dr. Haggey suggests that there be a great deal of follow up assuring that these patients are doing what has to be done to decrease their risk factors.
There have been three very high quality clinical trials on patients who need carotid endarterectomy but are asymptomatic. Those trials are the Veterans Affairs Cooperative Study Group, the Asymptomatic Carotid Atherosclerosis Study, and the Asymptomatic Carotid ...Download file to see next pagesRead More

In order to reduce strain on the heart and relax the arteries, the patient may be given calcium channel blockers. Diuretics help decrease the blood pressure. Chest pain is cured with nitroglycerin which also improves the supply of blood to heart. Statins are prescribed to reduce the cholesterol level. Occasionally, the patient is required to undergo a surgery. Minimally invasive heart surgery and coronary artery bypass surgery are commonly employed for curing coronary artery disease.

Coronary Artery Disease

The heart becomes starved of its vital nutrients and the oxygen it needs to function properly. Whereas the signs and symptoms of heart disease are distinguished in the advanced stage of the illness, most persons with the disease show no sign of the illness for many years. When the disease shows its first signs, it is then followed by a sudden heart attack. After years of development, some of these plaques may rupture and start restraining blood flow to the heart muscle. From an early age, cholesterol-laden plaque can begin to accumulate in the blood vessel walls (Brubaker, 2001). As people get older, the plaque builds up, provoking the blood vessel walls along with raising the risk of blood clots, as well as heart attack. The pla...

The nurse should also emphasize the effectiveness of management pain with medications and reassure that it will be done quickly (Martin & Turkelson, 2006). During the intraoperative phase, the nurse’s role is minimal. Sometimes, nurses trained in coronary artery bypass graft assist during the surgery when in the operating room. Thus, they are required to have been trained to help conduct medical procedures and operate the equipment utilized during the surgery, which is done open-heart. They know the medications...

Understanding Spinal Stenosis

As in this case, initial clinical presentations of some patients are often complicated with several individual factors such as age and physical activity. In fact, signs, and symptoms a headache and dyspnea can be extremely subjective and may significantly vary with each patient judgment. Furthermore, some conditions do not immediately present to instantly warrant a thorough investigation, only manifesting when much damage has already occurred to be clinically evident. Possible aggravation of a previously known condition also contributes to the complexity of the case. As such, arriving at a logical and rational medical diagnosis may at times be challenged with the inconsistencies of observed and reported manifestations by the patie...

Use of Carotid IMT in risk stratification of hypogonadal men with atherosclerosis and coronary artery disease

... males, possibly being a cause in development of CAD. Studies have linked low testosterone levels with greater IMT. Thus it seems plausible to use low testosterone levels and carotid IMT in the screening and follow up of patients at risk for development of CAD and patients who have had CAD and are being managed for prevention of further events. 2) Use of carotid IMT as risk stratification tool and how it is measured Carotid IMT is a noninvasive procedure based on the use of the common Ultrasound technology with suitable modification. The technique uses a B-mode real-time ultrasound with a high resolution. B-mode ultrasound imaging technology has evolved to the extent that the walls of superficial arteries can be imaged non-invasively...

Carotid Endarterectomy

The patients considered for the study included those with significant internal carotid artery stenosis and those who were suitable and wished to have CEA. Fully accredited vascular technicians performed all the duplex scans by using the Bluthe criteria. A consultant radiologist reported the angiograms by using the North American Symptomatic Carotid Endarterectomy Trial (NASCET) criteria.
The sample size included 64 patients with a median patient age range of 70 years with a male to female ratio of 1.5 to 1. These patients were recruited over a two-year period. Of the 64 patients, 2 were asymptomatic, 25 patients had a previous cerebrovascular accident, 28 had a transient ischaemic attack (TIA), and 9 had amaurosis.

Computer Tomography Scan Angiography for Carotid Artery Stenosis

...Carotid Artery Stenosis Introduction The carotid arteries are the primary arteries which carry fresh, oxygenated blood to the brain and hence it is vital that they function properly.

Carotid Artery Stenosis is a condition which develops gradually and its detection at an early stage is vital for undertaking appropriate surgical or medical intervention. Extracranial carotid disease accounts for nearly one half of all cases of patients dying due to cerebrovascular accident (CVA) culminating in stroke (Nadalo & Walters. 2009). The annual mortality figure for patients affected by CVA is 150,000 worldwide...
