Exam 2 Review Flashcards
fibrillation
irregular fast heart rate, can lead to blood clots
thrombus
stationary clot attached to vessel wall
coronary thrombus
thrombus in blood vessel of the heart
embolus
moving clot
can thrombus go to embolus?
yes from the pressure of blood
congestive heart failure
heart muscles don’t pump as well as they should - inadequate blood to organs
stable angina
chest pain, stress or exercise
embolism
obstruction of artery
arteriosclerosis
stiffening or hardening of blood vessels
atherosclerosis
narrowing from plaque build up
metabolic syndrome
waist circumference - 31 in Asian Americans
high triglyceride
how HDL
elevated BP
elevated fasting glucose
unstable angina
no pattern of pain or at rest, lasts longer, rest and medication don’t relieve
sign of heart attack
variant angina
pain at rest, temporary artery spasm, younger women under 50, smaller lumen
management for Angina drugs
nitrate
beta blocker
Calcium channel blocker
anti platelet drugs
what do you look for patient evaluation
co-morbidity (2 or more diseases at same time), company atherosclerosis - diabetes, high lipid, hypothyroid, vascular disease
reduce risk of angina
lower LDL to less than 100
ischemia
no tissue death - causes reduction of blood flow
infarction
prolonged cessation of blood flow (blood flow reaches zero) causes tissue death
why is presence of cardiac enzymes a major sign of infarction
when the cells are dying they can’t hold the structure and release content to other areas - cells are dying if you can detect them
heart attack in men
pain in chest
lightheadedness, nausea, vomiting
jaw, neck, back pain
discomfort or pain in arm or shoulder
shortness of breath
heart attack in women
flu like
pressure, squeezing, fullness or pain in chest
pain or discomfort in arms, back, jaw, stomach
shortness of breath
cold sweat, nausea, vomit, lightheaded
chest pain or discomfort
male patterns of heart attack
obstruction in coronary vessel
male heart attack diagnostic
stress test, coronary angiography
male heart attack treatment
angioplasty, bypass surgery, statins
female heart attack patterns
microvascular coronary dysfunction, inflammation
female heart attack diagnostic
stress test, functional vascular imaging, cardiac MR, IVUS
female heart attack treatment
anti-hypertensive, anti inflammatory, statins
women ____ men ___
women erode, men explode
most common area for infarction and most lethal
left anterior descending artery
widow maker - kills
Clotting process
- monocytes go to area of injury in blood vessel
- covered to macrophages that engulf fat and turn to foam cells
- foam cells die and deposit under endothelium
smooth muscles go to top to form fibrous cap - when cap ruptures it exposes atheroma and stimulate coagulation forming coronary thrombus
- can obstruct artery that lead to AMI
million hearts initiative
focus, coordinate, enhance cardiovascular disease prevention activities
life’s simple 7
get active
control cholesterol
eat better
manage blood pressure
lose weight
reduce blood sugar
stop smoking
go red for women
raise awareness about heart disease and stroke in women. take charge of heart, red as symbol to untie women
transmural
death tissue on layers of the heart
sub endocardial
death of tissue is located just underneath the endocardial layer
AMI complications - 7
- Arrhythmias - AF, VF, heart block
- heart failure
- intracardiac thrombi
- pericarditis
- papillary muscle dysfunction
- ventricular aneurysm
- cardiac rupture - worst
hypertension nickname
silent killer because you don’t know it’s going to happen until it happens
diagnostic of hypertension?
blood pressure measurements
primary hypertension
no known cause
secondary hypertension
there is a known cause
isolated systolic hypertension
same effects as primary and secondary
rise in systolic
lower diastolic
what percentage of people will develop hypertension in the next 4 years with a BP of 120-139/80-89
50%
hypertension urgency
asymptomatic for signs
hypertensive emergency
shows signs and symptoms
complications of hypertension
CVD mortality and morbidity
increase systolic and diastolic BP
older than 50 have increase in systolic and pulse pressure - predictor of complications than diastolic
inaccurate BP readings-7
talking or active listening - adds 10
full bladder - adds 10
unsupported back and feet -adds 6
crossed legs - addes 2-8
unsupported arm - adds 10
cuff over clothing - add 5-50
cuff too small - add 2-10
lifestyle modifications
reduce weight - highest BP reduction
increase aerobic physical activity - average SBP reduction 4-9
moderation in alcohol, 2 for men, 1 women
restrict sodium 1.5-2.4 g/day 2 if with CHF and kidney disease
modify eating plan - dash 8-14 SBP reduction
dash diet
high fruit, vegetable, low fat dairy
low total fat, saturated, cholesterol
stroke risk factors
age
gender
family history
high blood cholesterol
high blood pressure
physical inactivity
obesity and overweight
smoking
diabetes
TIA (transient ischemic attack)
less than 24 hour stroke, symptoms resolve, not permanent damage
s/s of TIA
loss of sensation in arm or leg, opposite side of body
temporary reduction of brain supply
think or speaking
short speech
partial loss of vision
causes of TIA
platelets, blood clot, fatty material calcium on carotid artery
ischemic stroke
blockage of blood vessel supplying Brian by embolus or thrombus
- clot from fatty deposit
- can cause cerebral thrombosis
- cerebral embolism
cerebral embolism
blood clot in another part of the circulatory system which breaks loose from an artery or the heart and travels to the brain where the blood vessels are too small to pass it
- causes obstruction of blood flow in brain - lack of oxygen
hemorrhagic stroke
rupture of blood vessel with bleeding into or around the brain
- causes by weak vessels that rupture
- compression on brain tissue where blood is
- pressure damage to brain cells inhibits proper function of brain tissue
- 20% of strokes are more serious and frequently fatal, extensive damage to brain tissue, pre-existing hypertension
- both last more than 24 Hours
strokes in right hemisphere of brain -7
impair judgement
short term memory
one-sided neglect
spatial and perceptual abilities
loss of sensation, reflex changes
controlling emotions
dysarthria
stroke in left hemisphere of brain
aphasia - partial loss or total loss of ability to communicate verbally or writing

difficulty learning new information, login, problem solving
prevention treatment
reduce risk factors
immediate treatment after stroke
acute or while stroke is evolving - dissolve blood clot or stop bleeding
post - stroke rehabilitation
reduce stroke damage
