Pathophysiology of Coronary Artery Disease

This condition is chronic and begins when a person is an adolescent and then it slowly progresses throughout their life. Coronary artery disease pathophysiology revolves around a few theories. One widely accepted theory is that this condition occurs when the body is trying to heal itself as a result of endothelial injury. Inflammation is also beginning to be accepted as a critical component of potential plaque instability and atherosclerosis activity. Patients who have been diagnosed with established coronary artery disease and have several of the causes and/or risk factors as well are at a much higher risk of experiencing a cerebrovascular accident, myocardial infarction, and other vascular events in the future.

Elevated C-reactive protein levels, and other elevated biochemical markers, indicate a higher risk of experiencing a vascular event in the future and it indicates an increased likelihood of vascular inflammation. This marker may also indicate the need for aggressive preventative measures due to the patient having a quickly advancing coronary artery disease.

Pathophysiology of Congestive Heart Failure (CHF)

Congestive Heart Failure (CHF) Congestive heart failure, or heart failure, is a condition in which the heart is unable to adequately pump blood throughout the body and/or unable to prevent blood from "backing up" into the lungs. In most cases, heart failure is a process that occurs over time, when an underlying condition damages the heart or makes it work too hard, weakening the organ. Heart failure is characterized by shortness of breath (dyspnea) and abnormal fluid retention, which usually results in swelling (edema) in the feet and legs. Pathophysiology of Congestive Heart Failure (CHF) Heart failure occurs, the body undergoes some adaptation, both in heart and systemically. If the stroke volume of both ventricles is reduced, because of pressure contractility, or afterload are greatly increased, the volume and pressure at the end of diastolic heart in two space will increase. This will increase the end diastolic myocardial fiber length, causing systolic time beco...

Hematemesis Melena Pathophysiology

A history of dyspepsia, peptic ulcer is the initial allegations. So is a history of recurrent vomiting who initially did not bleed, excessive alcohol consumption leads to the suspicion of gastritis and peptic ulcer disease. A history of recurrent vomiting who initially did not bleed more towards Mallory-Weiss. Excessive alcohol consumption leads to allegations of gastritis (30-40%), peptic ulcer disease (30-40%), or sometimes varicose veins. Weight reduction leads to the suspicion of malignancy. Heavy bleeding accompanied by a clot and refractory shock treatment increases the likelihood of varicose veins. A history of previous abdominal aortic surgery increases the likelihood of fistula aortoenterik. At the young age of patients with a history of upper gastrointestinal bleeding brief repeated (often accompanied by hemodynamic collapse) and a normal endoscopy, should be considered Dieulafoy lesion (a submucosal artery, usually near the heart, which can cause intermittent gastrointestina...

Pathophysiology of Appendicitis

Appendicitis The appendix is a small, tube-like organ attached to the first part of the large intestine, also called the colon. It is located in the lower right area of the abdomen. It has no known function. A blockage inside of the appendix causes appendicitis. The blockage leads to increased pressure, problems with blood flow and inflammation. If the blockage is not treated, the appendix can break open and leak infection into the body. Pathophysiology of Appendicitis The main cause of appendicitis is obstuksi blockage which can be caused by hyperplasia of the follicles lympoid is the most common cause of fekalit in appendix lumen. The presence of foreign objects such as: worms, stricture due to fibrosis, as a result of previous inflammation. For another example: malignancy (carcinoid carcinoma). Appendix obstruction that causes mucus produced by mucous unstoppable, more and more mucus is unstoppable and suppress edema appendix wall and stimulate the tunica serosa and vis...
