cardiovascular disease test 2 Flashcards
what is cardiovascular disease
group of disorders of the heart and blood vessels
-there are multiple types of CVD
why do health psychologists spend so much time with CVD
- an excellent example of health consequence that can occur due to risky lifestyle choices
- many cardiovascular diseases are preventable, meaning they occur due to factors within our control
what is atherosclerosis
deposits of fat, cholesterol, calcium and other substances (plaque) lines arteries
what are the three key points about CVD
1) plaque narrows passageway of arteries which leads to reduced blood flow
2) plaque hardens arteries which makes them inflexible
3) usually plaque buildup is a result of diet
what is cardiac arrest
caused by ventricular fibrillation, abnormal heart rhythm that occurs when the heart fails to pump blood to other organs, will cause unconsciousness and will be fatal if heart isn’t synchronized
heart disease facts in US
- causes 1/4 deaths
- leading cause of death for men and women
what is angina pectoris
squeezing, tightness or pain in the chest usually caused by CVD
- warning sign the heart is not getting adequate blood and oxygen supply
- if ignored may lead to heart attack
what is automated external defibrillator (AED)
send electrical charge to the heart that is meant to restart circulation process
what is cardiopulmonary resuscitation (CPR)
stimulates the heart and provides O2 to lungs
Without medical attention to a heart attack someone can die in 10 minutes or less
what are sudden cardiac arrest stats in US
- sudden cardiac arrest happens to 326,000 a year and can happen anytime to anyone
- less than 10% survive
who is most likely to experience mortality/morbidity
- coronary artery disease more prevalent in men at every age group except 20-39 (equal for men and women)
- risk increases with age
- average age for 1st heart attack is 65 (between 4-10% occur before 45, mostly in men)
- 80% of young heart attacks due to atherosclerosis (due to diet, is identifiable in late teen years)
what is heart attack incidence
- risk increases with age
- black men and women have higher rates than whites
- men have higher rates overall
- white women have lowest overall rates
what is cerebrovascular disease/stroke and the two types
affects the vessels that carry blood and oxygen to he brain
1) ischemic: interruption of blood flow to the brain
2) hemorrhagic: rupture of blood vessel to brain
what are some differences between ischemic and hemorrhagic stroke
- ischemic is most common (80% of all strokes)
- hemorrhagic have a higher death rate because more difficult to treat
what are the stroke rates
hemorrhagic has remained stable
rates for ischemic have decreased
explain stroke awareness
- one side of face falls, weakness in arms, slurred speech
- call 911 if these symptoms exist
- 4% improvement for patient prognosis for each 15 minute interval
- stroke cause irreversible injured tissue in the brain
explain stroke incidence
- most common in black men and women
- least common in white women
what are some non-modifiable risk factors for CVD
- race/ethnicity: cardiovascular reactivity- brief increases in blood pressure due to frustration (higher in blacks)
- age (risk increases with age)
- family history
- sex (earlier research said CVD more common in men but more women die within a year of heart attack and 2/3 of those who die have no previous symptoms)
So women have CVD develop later in life but have a worse outcome
what are risk factors for CVD
1) high total cholesterol
2) low HDL (good cholesterol)
3) high BP
4) diabetes
5) obesity
6) smoking
no risk factors = 5% chance of CVD
at least 2= 69% chance of CVD
what is hypertension
high blood pressure
-normal is 120/80 systolic/diastolic
symptoms include: headaches, palpitations, nose bleeds, etc.
-at least 1/3 have HBP, more have prehypertension
what is the “silent killer”
hypertension
-often goes undetected and if untreated can lead to organ failure, stroke, heart attack, etc
what are the two types of high blood pressure
1) essential/primary hypertension: no identifiable cause (lifestyle and genetics)
2) secondary hypertension: due to another underlying health issue
what is high BP prevalence
- increase with age
- more common in men until age 55-63, then equal, then more common in women
what is white coat hypertension
the stress of going to the doctor causes an increase in BP while you are there, but your BP at home is normal
-affects 1/3 of adults aged 50
