Document Summary
25% of the exam is the old stuff. Remember to go over function & valves & structure of vascular system. Vessels that are largely innervated subjected to amines and other things to regulate. Bacteremia, endocarditis, septic emboli, infectious arteritis , mycotic aneurysm ect. Atheroma- accumulation of fat factors- cholesterol, fat cells, ect. Ends up underneath epithelial to weaken blood vessels to cause aneurysm or to close off vessel. Saccular- bary aneurysm in the brain, involve only one side of the vessel. Progression from signs of ischemia to the fibrous scar replacement. Right- back flow from the right side causing congestion of peripheral and extremities. Left- insufficient output from the left side causing pulmonary edema, pleural effusions, sob, hypoperfusion of organs (renal failure), edema. Damage/ no damage to heart and distal organs, especially the brain. Secondary hypertension- attributable (medication, disease, pregnancy, caffeine, alcohol) Cor pumonale (lung disease > rv hypertrophy ) Benign (chronic hypertension)/ malignant ( sudden onset hypertension)
