Coronary Artery Disease (CAD), is a condition in which plaque builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart muscle. This plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. When plaque builds up in the arteries, the condition is called atherosclerosis, the buildup of plaque occurs over many years. Over time, the plaque hardens which causes your coronary arteries to narrow, which limits the amount of oxygen and blood your muscles are supposed to get to function properly. Coronary Artery Disease is the leading cause of death in the United States because of the people’s not so healthy diet, lack of exercise, and tendency to smoke, which are the leading causes of CAD. The symptoms might be very noticeable, or you might not experience anything. Some of the signs and symptom might include angina which causes major chest pain or at least some discomfort or abnormal feeling on your chest. Also, you may feel like your chest is closing up and it will become harder for you to breathe, also may experience pain on your neck, lower back. Fatigue and weakness are also symptoms for this as well along with what was mentioned. For treatment, your doctor will give you specific medications based on how severe your case is, eating habits will need to change, start exercising, and if a smoker, to quit smoking. If you are given medicine by the doctor be sure to take all the medicine don’t stop because you feel better. The reason why one is to take all the medicine is because if not finished it will come back but even worse than it was before. In very extreme cases, a stent placement, minimal invasive heart surgery will be needed in order to survive. Although everyone is different, early detection of CHD generally results in a better outcome. Even though one may be done with treatments one might be stuck with some long-term effects. One of them being Unstable Angina, which I said was a severe chest pain due to not enough oxygen going to the lungs. Heart failure could also happen, due to the lack of blood and oxygen being transported to the heart, it weakens which makes everything much difficult than before, this is a heart failure. A long- term coronary artery disease could lead to suffering heart attacks, which happens when the artery is completely blocked, so no oxygen or blood flowing through whatsoever. Coronary artery disease is a very harmful disease when not treated, but being healthy could prevent it.

Coronary artery disease is the condition of the narrowing of the arteries that supply oxygen and blood to the myocardium (heart muscle). The narrowing is caused by a substance called plaque, which contains deposits of fat that cause blockages within the arteries. The blocked arteries then become hardened (atherosclerosis) and narrow, not allowing adequate…

Coronary artery disease is one of the most prominent forms of heart disease. It occurs when the coronary arteries that supply the heart blood become narrowed, and eventually occluded. This narrowing typically takes place because of plaque build up due to cholesterol and other fatty substances being ingested, also called atherosclerosis. This thickening of the artery wall can take many years, eventually completely inhibiting blood flow. Because the blood flow has stopped, little oxygen gets to the heart, and the myocardial cells therefore die. This is when a heart attack ensues, also called a myocardial infarction.…

Angina is another symptom of CHD. Angina is a pain that comes from the heart. This can be caused by a build up of fatty deposit or a collapsed arterial wall, resulting in the blood having difficulties to flow freely and quickly to the heart. The signs for angina are; chest pains, pins and needles down the left arm, up to the neck, jaw ad into the back. Pail skin, blue lips and nauseas are also some of the signs that can be…

1. Coronary Artery Disease is briefly described as a plaque blockage cutting off blood flow to your heart. Cholesterol deposits slowly, over decades, build up in the vessel wall and cause a decrease in blood flow. A patient with decreased blood flow to the heart may have angina, shortness of breath, and in some cases a myocardial infarction.…

CAD is thought to begin with damage or injury to the intimal layer of coronary artery, sometimes as early as childhood. The damage may be caused by various factors, including: smoking, hypertension, hypercholestromia, diabetes or insulin resistance, radiation therapy to the chest, as used for certain types of cancer, and sedentary lifestyle. Once the intimal layer of coronary artery is damaged, fatty deposits (plaques) made up of cholesterol and other cellular waste products tend to accumulate at the site of injury in a process called atherosclerosis. If the surface of these plaques breaks or ruptures, platelets will clump at the site to try to repair the artery. This clump can block the artery, leading to a heart attack. Recent research has…

One of the first symptoms of coronary artery disease is known as angina pectoris commonly referred to as chest pain. It is the most common form of temporary ischemia that develops when the muscles of the heart doesn’t get enough blood supply. This type of symptommay occur when an individual is exercising or may even occur at rest. Sometimes before they realize that something is wrong, emotional stress can produce a sensation of pressure, chest constriction, or pain that may radiate from the sternal (chest) area to the arms, back, or neck. That is when you may realize that one is having problem.…

Coronary Artery Disease (CAD) is the most common type of heart disease. I’m here to tell you all, it’s the leading cause of deaths in the United States in both women and men. (CAD) happens when the arteries that supply blood to the heart muscle becomes harden and narrowed. This is due to the buildup of cholesterol and/or plaque on the inner walls (MedlinePlus, 2012). To reduce your risk of getting (CAD) can potentially lead to heart failure. Leading to the next disease I want to discuss is Congestive Heart Failure. (CHF) is a condition in which the heart’s function as a pump is inadequate to meet the body’s needs (MedicineNet, 1996). From known knowledge, (CHF) can be based on many reasons for example, individuals medical history. I know as we age we all dislike going to the doctor’s office or hospital, but I’m here to tell you, we all need to go more often than normal. Getting careful physical examinations and selected laboratory tests done can save your life. Lastly, I want…

The cardiac muscle of the heart wall depends on a constant flow of blood supply by the coronary arteries. Coronary arteries are blood vessels that arise from the base of the aorta and bring freshly oxygenated blood to the heart muscle. If this supply is restricted, then oxygen and nutrients can’t reach the muscles and the result could be a form of coronary artery disease (CAD). It can also be known as coronary heart diseases (CHD). This form of partial or complete block can be caused by fatty deposits, blood clots, or both. Overall, the extent of the symptoms of coronary artery disease depends on the location, severity, and how fast the disease will start from the limited blood supply.…

I think most of them forget that we do not understand the terminology that they use when speaking to us. So having taken some classes in medical terminology and a little knowledge of the different disease of the body, I will do my best to explain things in a fashion that you can explain to your sister so she may be able to understand what is going on with her at this moment. First I will start by explaining to you what an Aortic Aneurysms is. An aortic aneurysm is a weak spot in the wall of the aorta, the primary artery that carries blood from the heart to the head and other extremities. I most cases people with aortic aneurysms in the chest area do not experience symptoms, but can have symptoms if the aneurysm gets bigger or causes pressure on the surrounding organs. You need to explain that she needs to really pay attention to the most common symptoms which are chest pain, back pain, difficulty swallowing, and shortness of breath. Treatment can vary with each patient depending on if the doctor feels you need surgery or not, if you will be able to withstand a major surgery, and if the surgery can be avoided for at least the present time. The treatments that are known for best ways of treating aortic aneurysm are medication such as a beta-blocker. Small aneurysms lest than 5.5 cm that are not at risk of rupturing are generally treated with medicine that is used to treat high blood pressure, but when the aneurysm gets above 5.5 cm to 6.0 cm in size the doctor will most likely recommend surgery. And one that is most important form of treatment for aortic aneurysm is to quit smoking cigarettes if you smoke them. I hope this helps you to understand some of the symptoms that are noticeable with an aneurysm so that you can help your sister to understand too. Also I hope my explanation of the treatments will help your…

Coronary heart disease is most often caused by a condition called arteriosclerosis, which takes place when a fatty material along with a substance called plaque builds up along the walls of the coronary arteries causing them to become narrow and restrictive. As the coronary arteries grow rigid and narrow, the combination can restrict the blood flow to the heart causing it to stop or slow down resulting in chest pain, stable angina, shortness of breath, along with other symptoms, eventually resulting in a heart attack (Blank & Smithline, 2002). However, most individuals with coronary artery disease do not display symptoms of the disease for decades, even as it progresses. The first onsets of symptoms are often sudden resulting in myocardial infarctions, also known as heart attacks. (American Heart Association, 2011; DeVon, & Zerwic, 2003).…

Coronary heart disease or CHD is a narrowing of the small blood vassals that supply the heart with blood and oxygen. The disease develops when a combination of fatty material, calcium, and scar tissue or plaque, builds up in the arteries that supply the heart with blood. This slows the blood flow and causes chest pain. Men in their 40s have a higher risk of CHD than women. But, as women get older, their risk increases so that it is almost equal to a man's risk.…
