PATHOPHYSIOLOGY OF MYOCARDIAL INFARCTION Mechanisms of Occlusion Most MIs are caused by a disruption in the vascular endothelium associated with an unstable atherosclerotic plaque that stimulates the formation of an intracoronary thrombus‚ which results in coronary artery blood flow occlusion. If such an occlusion persists long enough (20 to 40 min)‚ irreversible myocardial cell damage and cell death will occur.5 The development of atherosclerotic plaque occurs over a period of years to decades

Pathophysiology Infection and inflammation of the kidneys is called pyelonephritis. Pyelonephritis is a type of urinary tract infection. E. coli is the most common microbe that causes pyelonephritis. It usually begins in the urethra or bladder and travels to the kidneys. There is a chance of it spreading to the calyces and medullary tissues such as the tubules of the nephrons. If not treated the glomeruli will also be infected and inflamed. (Bullock & Hales 2013). There is both acute pyelonephritis

A stroke is a serious medical issue that can affect an individual at any moment. A stroke occurs when the flow of blood in the direction to the brain is blocked‚ due to a lack of oxygen (Ischemic stroke)‚ or when there is bleeding in the brain‚ causing brain cells to damage and/or die (Hemorrhagic stroke). Individuals of an older age are more likely to have a stroke‚ than individuals of a younger age. Individuals who experience a stroke would show the symptoms of sudden weakness; the inability to

of Paediatric Stroke The treatment of ischemic stroke is involve both initial treatment of acute stroke to preserve neurological function and continuous treatment to prevent recurrent stroke which occurs in 10% and 25% of children with stroke.

speech difficulty. The emergency room physician‚ who also specialized in neurology‚ immediately suspected that the patient suffered from a stroke. Stroke occurs when the blood flow to a certain part of the brain is blocked‚ which causes the blood vessels to burst or leak within the brain. This leak of blood in the brain causes nerve cells to die (“What is Stroke?” 1). To confirm his doubts and diagnoses‚ the physician ordered the background information and medical history of the patient. According

Let’s face it‚ in the eyes of the modern day motocross racer‚ 2 strokes are a thing of the past. But don’t let anyone fool you into thinking that a camshaft equipped bike is superior to the modern day 2 stroke though. The 4 stroke equipped dirt bikes have the upper hand thanks to race rules regarding engine displacement. To help make them competitive they literally doubled the displacement for what is allowed for a 2 stroke. As the 4 stroke evolved and progressed over a few short years it was clear they

Exam Case Scenario Pathophysiology of Asthma Asthma is a chronic lung disease characterized by episodes in which the bronchioles constrict due to oversensitivity. In asthma‚ the airways (bronchioles) constrict making it difficult to get air in or out of the lungs. Breathlessness is the main symptom. The bronchi and bronchioles become inflamed and constricted. Asthmatics usually react to triggers. Triggers are substances and situations that would not normally trouble an asthma free person. Asthma
