Perfusion Flashcards
(17 cards)
What is primary hypertension?
No identifiable cause
What is an HTN emergency? How do we treat it?
SBP >180 & DBP>120 with organ damage
- decrease BP 25% within 1st hour
- goal 160/100 over 2-6 hours
- decreasing BP too quickly decrease cerebral perfusion
- goal 160/100 over 2-6 hours
Medications for atherosclerosis?
• Lipid Lowering medications • Anti-platelet medications • Beta blockers • Angiotensin-converting enzyme (ACE) inhibitors • Calcium channel blockers
Important lab assessments for atherosclerosis
Total serum cholesterol < 200mg/dl (considered normal)
– Lipid Profile – Total Cholesterol <200mg/dl
– LDL-C <100 mg/dl (healthy), <70 mg/dl (CAD, DM)
– HDL-C >40 mg/dl exercise
Triglyceride <150 mg/dl
– if > 150 mg/dl hypertriglyceridemia
Women < 135 mg/dl
What is white coat HTN?
> 130/90 in healthcare setting & normal outside setting
What is atherosclerosis
A type of arteriosclerosis
• Thickening & hardening due to increased cholesterol
development
• Affecting larger arteries i.e. aorta, carotid
Side effects of questran? (Bile acid sequestrants)
Side effects: constipation, increase bleeding r/t vit K
malabsorption and vit A,D deficiencies
What are risks of HTN?
Race
- Increased incidence in African Americans (30%)
Elderly
obese
Age (30-70years)
< 45 years of age – Males > Females; > 45 years of age - Females = Males
Diet
Alcohol intake
1 out of 3 adults will develop hypertension in their lifetime. (AHA 2010)
Accounts for 50 Million people in the United States
Sleep Apnea
Family History
Smoking
Sedentary Lifestyle
Diabetes mellitus
How do we diagnose HTN?
• BP – 2 or more seated BP readings on each of 2 or more office visits
• EKG – measures electrical impulses across the heart
muscle
• Echocardiogram – ultrasonic waves are directed to the
heart. Gives a picture. Detects valve disorders,
congenital disorders, fluid around the heart, heart
tumors
• Cardiac Catheterization – determines BP and blood
flow into the heart chambers
Common side effects of fibrates?
Nausea and abdominal pain
Teaching: take 30 mins before morning and evening meal.
May increase effects of anticoagulants and
hypoglycemia
What is arteriosclerosis?
A broad term applied to any number of
pathological conditions where there is thickening, hardening, & loss of elasticity of arteries.
Causes: heredity, diet, smoking
What is orthostatic hypotension?
Dec BP SBP>20mmHg or DBP >10mmHg with change in position
20 min switch each position
What is masked HTN?
Normal in healthcare setting & high @ home/work
• R/T stress, smoking
• Educate: reduce stress, smoking cessation, monitor BP stress
What are some antihyperlipidemic meds?
Statins (atorvastatin)
Fibrates (fenofibrate)
Bile Acid Sequestrants (colestipol)
Niacin (niacin)
Cholesterol Absorption Inhibitor (ezetimibe)
Combination Agent (Vytorin: ezetimibe+simvastatin)
What are some special considerations for meds involving race?
African Americans respond better to diuretics
Caucasians – ACE inhibitors
What is secondary hypertension?
Identifiable cause i.e. med., renal disease, hyperaldosteronism
What is an HTN urgency? How do we treat it?
SBP>180/DBP>110 without organ damage, symptoms severe H/A, SOB, anxiety, nose bleeds. Goal is 160/110 BP over several hours.
Treated with oral meds
