Care of Patients with Vascular Problems Flashcards
Arteriosclerosis:
thickening, hardening of the arterial wall that is often associated with aging
Atherosclerosis:
type of arteriosclerosis, involves the formation of plaque w/in the arterial wall and is the leading risk factor for cardiovascular disease
Palpate each carotid artery separately to
prevent blocking blood flow to the brain
What indicates hypertriglyceridemia?
level of 160 mg/dL or above in men
Women should have level below 135
Recommendations for nutrition: Arteriosclerosis
Intakes of veggies, fruits, whole grains
Consume low-fat dairy products, poultry, fish, legumes, nontropical vegetable oils, and nuts
Limit intake of sweets, sugar-sweetened beverages, and red meats
5% to 6% of calories from saturated fat
Reduce trans fat
Physical activity Arteriosclerosis
3-4 X a week
Drug therapy: Arteriosclerosis
3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors = reduce cholesterol
Complementary therapies: Arteriosclerosis
Nicotine acid or niacin B vitamin lower LDL-C very low density lipoprotein (VLDL) Increase HDL-C levels
4 control systems play a major role in maintaining BP:
Arterial baroreceptor system
Regulation of body fluid volume
The renin angiotensin aldosterone system
Vascular autoregulation
Found primarily in the carotid sinus, aorta, and wall of the left ventricle
arterial baroreceptors
Changes in fluid volume also affects the
systemic arterial pressure
Keeps perfusion in the body relatively constant, appears to be important in causing hypertension
Vascular autoregulation
the most common type of hypertension and is not caused by existing health problem
Essential (primary)
Primary hypertension results in
damage to vital organs by causing medial hyperplasia of the arterioles
Secondary hypertension=
specific disease states and drugs can increase person’s susceptibility to this
a severe type of elevated BP that rapidly progresses
Malignant hypertension
symptoms of malignant hypertension =
morning headaches, blurred vision, and dyspnea and/or symptoms of uremia (accumulation in the blood of substances ordinarily eliminated in the urine)
Diastolic pressure is greater than 150 mm Hg or greater than 130
Etiology and genetic risk =
Kidney disease: renal artery stenosis (RAS) Primary aldosteronism Pheochromocytomas Cushing's syndrome Drugs
Adrenal mediated hypertension is due to
primary excesses of aldosterone
Primary aldosteronism, excessive aldosterone causes
hypertension and hypokalemia
Pheochromocytomas:
tumors that originate most commonly in the adrenal medulla and result in excessive secretion of catecholamines
Cushing’s syndrome:
excessive glucocorticoids are excreted from the adrenal cortex
Drugs that cause secondary hypertension
estrogen glucocorticoids mineralocorticoids sympathomimetics cyclosporine erythropoietin
