Cardiovascular Pathology Flashcards
most expensive CVD
heart disease
biggest % breakdown attributable to CVD is in what?
coronary artery disease
top 4 health behaviors that affect CVD
1] smoking
physical inactivity
nutrition
obesity
health/risk factors for heart diseases and strokes
family hx, genetics high cholesterol HTN diabetes mellitus metabolic syndrome
3 factors, 1 is present in almost 50% of CVD deaths
blood pressure
cholesterol
smoking
1 modifiable risk factor for hemorrhagic and ischemic strokes
HTN
defined as high BP, against the walls of the arteries
HTN
idiopathic HTN is what kind and what %
primary HTN
90-95% of cases
BP for HTN?
more than 140/90
identifiable cause
5-10% of cases
secondary HTN
ratio for HTN
1 in 3
ages 12-19 year olds have really poor score in what?
healthy diet score
signs and symptoms of HTN
headache vertigo flushed face blurry vision nocturnal urinary frequency
HTN prevention
PA/ exercise
weight control
diet modification
HTN diagnosis
BP CBC urinalysis serum cholesterol fasting blood glucose ECG
HTN treatment
ongoing medication
lifestyle modification
HTN prognosis
can lead to L ventricular hypertrophy
transport of cholesterol to cells
LDL
transports form body to liver
HDL
increased risk of CAD with what kind of cholesterols?
high LDL
low HDL
total cholesterol should be #
less than 200
LDL #
less than 160
HDL # for males and females
more than 40 for males
more than 50 for females
triglycerides #
less than 150
CO binds 250 times more readily to Hgb vs. oxygen
oxyhemoglobin curve
chronic hypoxia leads to?
increased HCT and increased risk of clots
CO damages?
epithelial lining
decreased coronary flow at rest and with exercise
increased HTN
vasoconstriction
family hx: higher risk of a relative who had their first coronary event are what ages?
less than 55 y/o for males
less than 60 y/o for females
first sign of coronary artery disease is..?
fatty streak
stable vs. unstable
stable= injury to one area unstable= formed and now floating around
plaque vasoplasm decreased CO low oxygen levels - lung disease
oxygen supply
exercise/activity
psychological stress
oxygen demand
causes:
total occlusion of artery
platelet activation with limited blood flow
vasospasm of diseased artery/pain
angina
consistent workload precedes ischemia
reduced by rest
stable angina
lower workload precedes ischemia
OR lasts longer
OR different quality
»women
unstable angina
