Coronary Artery Disease - Research Paper Example

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 plaques discharge chemicals that support the process of healing (Brubaker, 2001). However, they make the inside walls of the arteries extremely sticky. Then, other substances, like the lipoproteins, inflammatory cells, and calcium that circulate in the bloodstream begin fusing to the inside walls of the arteries. Finally, a narrowed coronary artery might develop new blood vessels that supply blood to the heart.

Nevertheless, during periods of increased stress or exertion, the new arteries may not be able to provide sufficient oxygen to the heart muscle (Brubaker, 2001). . It causes heart muscle death, heart muscle damage or, in the future, myocardial disfiguring without heart muscle regrowth. Persistent stenosis of the coronary arteries might stimulate transient ischemia that brings about ventricular arrhythmia. Ventricular arrhythmia is known to break into ventricular fibrillation that leads to death.

The disease is linked to smoking, hypertension as well as diabetes (Brubaker, 2001). A family history of CAD is one of the less serious predictors of the disease. A majority of the familial links to coronary artery disease are associated with common dietetic habits. Screening for coronary artery disease comprises of evaluating low-density and high-density lipoprotein levels along with triglyceride levels. In spite of much press, a majority of the alternative risk factors including C-reactive protein (CRP), homocysteine, coronary calcium, and Lipoprotein (a) have added little value to the usual risk factors of diabetes, smoking and hypertension.

In relation to clinics, dialysis patients who have angina often also have a reasonably typical record of exercise-stimulated chest pain that is comparable to those with standard renal function. Nevertheless, given the recurrent episodes of hypotension or low blood pressure during hemodialysis, angina is possibly the most widespread clinical manifestation of the coronary artery disease. Additional signs and symptoms, for instance exertional dyspnea, (interdialytic or intradialytic) sudden cardiac arrest or death, hypotension, as well as arrhythmias, can be observed.

In many mature persons, the illness will have manifested itself much earlier in their lives (Brubaker, 2001). Nevertheless, in others the illness will totally be silent until the
