Pathophysiology of Coronary Artery Disease

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.

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 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...

Pathophysiology of Meningitis

Pathophysiology of Meningitis Predisposing factors include upper airway infection, otitis media, mastoiditis, sickle cell anemia and other hemoglobinopatis, a new neurosurgical procedure, head trauma and immunological effects. Venous channels through the posterior nasopharynx, middle ear and mastoid tract to the brain and the veins near the channel meningen; all of these links that support the growth of bacteria. Organisms enter the bloodstream and cause an inflammatory reaction in the meningen and under the cortex, which can cause thrombus and decreased cerebral blood flow. Cerebral tissue due to impaired metabolism meningen exudate, vasculitis and hypoperfusion. Purulent exudate may spread to the base of the brain and spinal cord. Inflammation also spread to the wall membrane of the cerebral ventricles. Bacterial meningitis associated with intracranial physiological changes, which consisted of increased permeability of the blood, the defense area of the brain, cerebral edema an...
