Coronary Artery Disease Research Paper

1. Coronary Artery Disease:

Coronary artery disease develops when your coronary arteries — the major blood vessels that supply your heart with blood, oxygen and nutrients — become damaged or diseased. It is a result of plaque buildup in your coronary arteries -- a condition called atherosclerosis -- that leads to blockages. The arteries, which start out smooth and elastic, become narrow and rigid, restricting blood flow to the heart. The heart becomes starved of oxygen and the vital nutrients it needs to pump properly.

Symptoms:

Angina / Chest Pain: discomfort, or tightness that occurs when an area of the heart muscle is receiving decreased blood oxygen supply. A squeezing pressure, heaviness, tightening, burning or aching across the chest,

Abnormal enlargement or bulging of the aorta, the largest blood vessel of the body is not an unusual condition.

An aneurysm is a weakening or ballooning of a blood vessel. This process may occur in any artery in the body. Aneurysms may also occur in any part of the aorta, including the root, the arch, the ascending and the descending aorta. An aneurysm occurs when a segment of the vessel becomes weakened. The pressure of the blood flowing through the vessel creates a bulge at the weak spot, much as an overinflated inner tube can cause a bulge in a tire. The bulge usually starts small and grows as the pressure continues. Aneurysms are dangerous because they may rupture.

Symptoms:

Chest Pain& Back Pain: Almost any unusual sensation or feeling in the upper chest or back, however, may be due to an aneurysm of the aorta. Chest pain is usually the first sign of aortic dissection. It can be describe as a tearing or ripping pain in the chest when the aorta enlarges to a critical size and ruptures/dissects. Besides pain, increased sweating, a fast heart rate, rapid breathing, dizziness, and shock may occur.

It can be inborn or it can be caused by stress situations or toxic stuff. One or even more heart chambers may dilate, causing an increase of one of heart chambers. In other situations, some of heart walls may grow thicker. Cardiomyopathy may be caused by decreased blood stream to the heart, by succeeded muscle problems, exposure to such chemicals as alcohol, cocaine and medications used to cure cancer, that damage the heart. It may also have no evident cause (idiopathic cardiomyopathy).

6. Inflammatory Disease of Heart:

Myocarditis is in fact an inflaming of the heart muscle. It is frequently present with a severe attack of dyspnea or/and a disorderly heart beating and can develop fast. It is often caused by viral infections.

Pericardial disease is a sickness of the sac around the heart. The most common reasons: fungous or bacterial infections, traumas, cancer, or a preceding heart attack. Without any treatment pericardium infections may rapidly become serious. Pericardial disease may cause additional friction “rub” and the chest ache.

Endocarditis is an inflaming of the pellicle which divides the heart and the heart valves. It may be caused by microorganisms or by autoimmune processes.
