1) Coronary artery disease occurs when fatty deposits called plaque build up inside the coronary arteries. The coronary arteries wrap around the heart and supply it with blood and oxygen. When plaque builds up, it narrows the arteries and reduces the amount of blood that gets to your heart. This can lead to serious problems, including heart attack. 2) Coronary artery disease is usually caused by a build-up of fatty deposits on the walls of the coronary arteries.
It could be chronic and is caused by the narrowing of the coronary artery and limitation of blood supply to part of the muscle. It also could be acute, which is the result from plaque suddenly rupturing. The inner wall of an artery is damaged. Some fatty deposits or plaques made up of cholesterol and other cellular waste products will accumulate at a site of injury in a process called atherosclerosis, the hardening of arteries. If the surface of the plaques break or rupture, blood cells, called platelets will clump or clot at that site to try and repair the artery.
They have either suffered a myocardial infarction or simply had angina (chest pain) that was evaluated with coronary angiography. CAD was noted during the angiography. Other tests are used to help diagnose CAD, electrocardiogram (ECG), stress test, echocardiogram, and blood tests. Treatment includes medicines, lifestyle changes, change in diet, and medical procedures. Treatments can be considered as preventions as well.
Atherosclerosis is a multi focal, smoldering immunoinflammatory disease of medium sized and large arteries filled by lipids. (Curtis M. Rimmerman, 2008) When plaque builds up the condition is called Atherosclerosis, the build up of plaque over many years.If the flow of oxygen rich blood to your heart muscle is reduced or blocked, Angina or a heart attack can occur. Angina is chest pain or discomfort. It may feel like pressure or squeezing in your chest. Pain can also occur in the shoulders, arms, neck, jaw or back.
Therefore, platelets undergo degranulation the exocytosis of their cytoplasmic granules and release of factors that promote hemostasis. Aggregation is occurs when serotonin (vasoconstrictor), ADP (attracts more platelets and stimulates their degranulation), and thromboxane A2 (stimulates degranulation and vasoconstriction) are released. Thus it can quickly seal a small break in blood vessel. Coagulation is the last process of the hemostasis. It has three ways; intrinsic, extrinsic and common pathways.
The patient is also receiving multiple courses of respiratory treatment, including vest therapy, cough assistance and nebulizer treatments. Hypoxemia: Abnormally low levels of oxygen in the blood. Hypoxemia may be mild to severe and leads to shortness of breath. Low blood oxygen can result from a variety of conditions that affect either the ability of the heart to pump blood to the lungs to receive oxygen or the function of the lungs themselves. Cerebral hypoxia can be caused by any event that severely
These consequences affect all the organ systems in the body. (Carol Mattson Porth, Glenn Matfin 2009) Cause: The presented patient scenario along with the information given indicate that Ms. Smith suffers from ARF that is caused by severe dehydration. This severe dehydration in turn produces Prerenal acute renal failure due to decrease renal blood flow and decrease glomerular perfusion and filtration. Based on the above patient diagnosis the labs would be as follows: K or potassium will be elevated to more than the normal ratio: K >5 Creatinine elevated: >2 Bun elevated: >20 Urea & sulfate will be elevated Sodium levels will be normal or low Calcium will be low & phosphate will be high. Hgb will be low: <12 Urinalysis: patient has low urine output and urine will have low specific gravity.
Stroke Awareness Health Assessment The self-risk assessment I chose to complete was about strokes. A stroke occurs when blood supply to the brain is temporarily interrupted or disturbed. Being that the brain requires a constant flow of oxygen any interruptions could prove to be fatal. The two types of strokes are Ischemic or hemorrhagic. An ischemic stroke is typically caused by excess buildup of plague on the blood vessel walls that narrows blood flow dramatically.
In some cases gallstones may be removed to relieve blockage of the pancreatic duct. In the most severe cases, surgery is needed to remove dead or infected pancreatic tissue. Complications from acute pancreatitis include acute kidney failure, ARDS, ascites, Cysts or abscesses in the pancreas, and heart failure. Repeat episodes can lead to chronic pancreatitis.

Read more about the symptoms of pressure ulcers. How pressure ulcers develop Pressure ulcers can develop when a large amount of pressure is applied to an area of skin over a short period of time. They can also occur when less pressure is applied over a longer period of time. The extra pressure disrupts the flow of blood through the skin. Without a blood supply, the affected skin becomes starved of oxygen and nutrients and begins to break down, leading to an ulcer forming.
