Document Summary

Classification of blood pressure normal = <120/80: prehypertension systolic 120-139 mmhg, diastolic 80-89 mmhg, stage i hypertension systolic 140-159 mmhg, diastolic 90-99 mmhg, stage ii hypertension systolic > 160 mmhg, diastolic > 100 mmhg. Hypertension/high blood pressure major cause of cva: primary 90% of cases, issues in the heart and/or blood vessels, secondary disease or condition that affects blood pressure i. e nephrosclerosis, hyperaldosteronism, pheochromocytoma, hypertensive crisis severe elevation. Loop diuretics i. e furosemide (lasix) act in the thick ascending limb of the loop of henle. Drugs used to treat chf different functions: ace inhibitors and vasodilators expand blood vessels and decrease resistance. Lipoproteins proteins on cell surface, phospholipids on outside, lipids inside center, soluble content on outside (water, blood, etc. ) Drugs to treat hyperlipidemia: statins i. e atorvastatin (lipitor) and rosuvastatin (crestor) reduce ldl (18-55%) and total triglyceride production (7-30%), increase hdl (5-15%) Lower cholesterol by inhibiting the enzyme hmg coa reductase, which is rate-limiting enzyme in cholesterol synthesis.
