answer

-it is a condition that underlies many cardiovascular health problems and is believed to be the biggest contributor to disease burden globally

question

As plaque accumulates, what causes? (atherosclerosis)

answer

as plaque accumulates, vessel walls become narrow and may eventually block blood flow or cause vessels to rupture -the pressure builds within arteries just as pressure builds in the hose (when put thumb over the end) -if vessels are weakened and pressure persists, they may burst or the plaque itself may break away from the walls of the vessels and obstruct blood flow -in addition, fluctuation in the blood pressure levels within arteries can damage their internal walls, making it even more likely that plaque will stick to injured wall surfaces and accumulate

question

atherosclerosis is often called _. why?

answer

a heart attack results from blockage of the main coronary arteries on the outer surface of the heart that provide blood supply to the heart muscle itself

question

atherosclerosis and other circulatory impairments also often _, a condition known as _

answer

atherosclerosis and other circulatory impairments also often reduce blood flow and limit the heart's blood and oxygen supply,, a condition known as ischemia

question

ischemia

answer

reduced oxygen supply to a body part or organ

question

coronary arteries (where located and function)

answer

coronary arteries are located on the exterior of the heart and supply blood and oxygen to the heart muscle itself

question

in atherosclerosis, what happens to arteries?

answer

arteries become clogged by a buildup of plaque

question

how atherosclerosis is related to heart attacks?

answer

when atherosclerosis occurs in coronary arteries, blood flow to the heart muscle is restricted and a heat attack may occur

question

what happens whenever blood does not flow readily?

answer

-whenever blood does not flow readily, there is a corresponding decrease in oxygen flow to tissue below the blockage

question

If the blockage of blood is extremely minor, how body adapts?

answer

-if the blockage is extremely minor, an otherwise healthy heart will adapt over time by enlarging existing blood vessels and growing new ones to reroute needed blood through other areas. This system is called collateral circulation

question

collateral circulation

answer

-adaptation of the heart to partial damage accomplished by rerouting needed blood through unused or underused blood vessels while the damaged heart muscle heals

question

collateral circulation is a form of _that allows an _to _

answer

-this system, called collateral circulation, is a form of self-preservation that allows an affected heart muscle to cope with damage

question

what happens when a heart blockage is more severe?

answer

-when a heart blockage is more severe the body is unable to adapt on its own, and outside lifesaving support is critical

question

what time following a heart attack is the most crucial period and why?

answer

-the hour following a heart attack is the most crucial period-with the events of the first hour after an attack being critical to survival

question

_% of heart attack victims die within the first hour following the heart attack

answer

40%

question

why women are more likely to have heart damage of heart attack and die than men of the same age?

answer

-women who suffer heart attacks under the age of 55 are not only less likely to have classic chest pain or pressure, but also they tend to delay going to the doctor -when they do seek medical attention, they often report more atypical symptoms, such as shortness of breath or pain in the neck, shoulder, arms, and stomach -Many women chalk up heart symptoms to stress, flu, or lack of exercise -Because of treatment delays, women are more likely to have heart damage and to die from a heart attack than men of the same age

for common signs or symptoms for both men and women see

answer

*see page 465 table 15.1*

question

how can women tell if she is having a heart attack?

answer

-the real answer to this question of how to tell if a women is having a heart attack is this: let a doctor determine that -If you or someone you know has even a few of these symptoms, do not delay. Take an aspirin and then have someone drive you to health care facility for evaluation, or call 911 to get an ambulance

question

what medicine to use if have symptoms or signs of heart attack? why? how will help?

answer

-if someone is feeling the symptoms or signs, crush or chew a full strength aspirin and swallow it with water -in addition of being a pain killer, aspiring has blood-thinning properties, so taking one can prevent fatal blood clots from forming

question

what to do when a heart attack hits? tips. what to do in case of a heart attack

answer

People often miss the signs of a heart attack, or they wait too long to seek help, which can have deadly consequences. Knowing what to do in an emergency could save your life or somebody else's: -Keep a list of emergency rescue service numbers next to your telephone and in your pocket, wallet, or purse. Be aware of whether your local area has a 911 emergency service -Expect the person to deny the possibility of anything as serious as a heart attack, particularly if that person is young and appears to be in good health. If you are with someone who appears to be having a heart attack, do not take no for an answer; insist on taking prompt action -if you are with someone who suddenly collapses, perform cardiopulmonary resuscitation (CPR). see www.heart.org for information on the new chest-compression-only techniques recommended by the American Heart Association. If you are trained and willing, use conventional CPR methods

question

question

two types of strokes

answer

-ischemic -hemorrhagic

question

explain an ischemic stroke

answer

caused by plaque formation or a clot that reduces blood flow

question

two ways to have a ischemic stroke caused by clots

answer

-a thrombus is a blood clot that forms inside a blood vessel and blocks the flow of blood at its origin. A thrombus in a cerebral artery can lead to an ischemic stroke -an embolus is a blood clot that breaks off from its point of formation and travels in the bloodstream until it lodges in a narrowed vessel and blocks blood flow. Emboli in brain blood vessels can cause ischemic stroke

question

answer

aneurysm is the most well known and most life-threatening of the hemorrhagic strokes

question

aneurysm

answer

-is the bulging of a weakened blood vessel wall -a weakened blood vessel that may bulge under pressure and, in severe cases, burst

question

how aneurysm in brain can cause strokes? (what kind of stroke?)

answer

-an aneurysm in the brain can cause hemorrhagic strokes if they burst

question

when any of the ischemic or hemorrhagic strokes happens, why the brain dies?

question

what age stroke rates increased the most?

answer

-that strokes rates (between 1995 and 2007) increased the most (up a dramatic 51%) among young men age 15 to 34 -stroke rates rose among women in this age group, too, but at a slower rate of 17^during the same time frame -young men are at particularly elevated risk for stroke

question

why stroke rates are high among young people? possible factors contributing to this. how stroke rates are changing for older adults?

answer

-although the growing prevalence of obesity, high-fat diets, increased sodium consumption, and sedentary lifestyle are mentioned as likely contributors, trends went in the opposite direction among older adults, with stroke rates dropping 25% in men aged 65 and older and down 28% among women in the same age group, -Better awareness of stroke risks among older adults and increased use of antihypertensive medicines are among the possible reasons for these declines -more research is needed to find out why young adults seem to be having more strokes

question

tips on recognizing a stroke (signs or symptoms of stroke)

answer

-people often ignore, minimize, or misunderstand stroke symptoms. Starting treatment within just a few hours is crucial for the best recovery outcomes. So if you suspect someone is having a stroke, use the "Cincinnati Prepositional Stroke Scale" to clarify what may be happening. Many emergency medical teams have adopted this tool to evaluate patients. Anyone with 3 abnormal signs has an over 70% likelihood of stroke: 1. Facial droop: ask the person to smile. it is normal for both sides of the face to move equally, and it is abnormal if one side moves less easily 2. Arm Drift: Ask the person to raise both arms. It is normal if both arms move equally (or not at all). it is abnormal if one arm drifts or cannot be raised as high as the other 3. Speech: Have the patient restate a sentence such as, "You can't teach an old dog new tricks." It is normal if they say the sentence correctly, and it is abnormal if they use inappropriate words, slur, or cannot speak

question

one of the greatest medical successes in recent years has been the_. explain how

answer

-decline in the death rate from strokes, which has dropped by over 1/3 in the US since 1980s and continues to fall -improved diagnostic procedures, better surgical options, clot-bursting drugs injected soon after a stroke has occurred, and acute care centers specializing in stroke treatment and rehabilitation have all been factors

question

Unfortunately, like many victims of other forms of CVD, stroke survivors do_(how recover, how people are left after stroke, problems)

answer

-do not always make a full recovery -problems with speech, memory, swallowing, and activities of daily living and other consequences can persist, even with physical therapy and medications -depression is also an issue for many post-stroke survivors

question

hypertension

answer

sustained elevated or high blood pressure

question

hypertension is known as_. why?

answer

-silent killer because it often has few overt symptoms

question

how prevalence of hypertension has changed? what age group is increasing in chances of having it?

answer

-common in women who take oral contraceptives than in women who do not take them

question

Blood pressure is measured by 2 numbers:

answer

-systolic blood pressure -diastolic blood pressure

question

how you report blood pressure? include which number is which

answer

ex: 110/80 mm Hg, stated as "110 over 80 millimeters of mercury" -The top number is systolic blood pressure and the bottom number is diastolic blood pressure (systolic/diastolic) trick: S/D

question

systolic blood pressure

answer

-the upper number in the fraction that measures blood pressure, indicating pressure on arterial walls when the heart contracts -refers to the pressure of blood in the arteries when the heart muscle contracts, sending blood to the rest of the body -When heart contracts, or beats, it sends a surge of blood through the vessels, increasing blood pressure. This is called systolic pressure.

question

diastolic pressure

answer

-the lower number in the fraction that measures blood pressure, indicating pressure on arterial walls during the relaxation phase of heart activity -refers to the pressure of blood on the arteries when the heart muscle relaxes, as blood is reentering the heart chambers -When your heart relaxes between beats, your blood pressure decreases. This is called diastolic pressure.

question

normal blood pressure varies depending on _(factors of blood pressure)

answer

-age, weight, and physical condition

question

how both types of blood pressure change with age?

answer

question

how coronary heart disease related to heart attack? how differs from atherosclerosis? (teacher source)

answer

-Coronary heart disease is the build up of plaque in the lining of the arteries. If the flow of oxygen rich blood is reduced or blocked, that is called a heart attack. -The difference really comes down to where the plaque build up is. For Coronary heart disease (CHD) the plaque builds up inside the coronary arteries. (These arteries supply blood to your heart). For atherosclerosis, the plaque builds up in the arteries (general definition).

question

can you die from a broken heart?

answer

-as first described in a 2005 article in the New England Journal of Medicine, researchers reported "broken heart syndrome," which has come to be known as stress cardiomyopathy. In this phenomenon, the heart is so stressed by traumatic emotional events that it receives a "concussion," a type of heart attack triggered by extreme, overwhelming stress, grief, horror, or anger. This is believed to affect 6% of women who have an apparent heart attack

question

underlying causes of congestive heart failure (CHF) include:

question

explain how triglyceride as risk factor in CVD. how these levels change as age?

answer

-high counts of blood triglycerides are often found in people who are obese and overweight and have high cholesterol levels,heart problems, or diabetes -as they age, particularly if they gain weight, people's triglyceride and cholesterol levels tend to rise

question

to prevent cholesterol and triglycerides risk associated with CVD, what test to take? at what age? gender?

answer

-it is recommended that a baseline cholesterol test (known as a lipid panel or lipid profile) be taken at age 20, with follow-ups every 5 tears -Men over the age of 35 and women over the age of 45 should have their lipid profile checked annually, with more frequent tests for those at high risk

-Fish high in omega-3 fatty acids -olive oil -whole grains and fiber -plant sterols and stanols -nuts -green tea -red wine *for specific types of food and how help you to reduce risk of CVD see page 473*

question

body weight plays a role in_. why?

answer

-CVD -researchers are not sure whether high-fat, high-sugar, high-calorie diets are a direct risk for CVD or whether they invite risk by causing obesity, which strains the heart, forcing it to push blood through the many miles of capillaries that supply each pound of fat. A heart that has to continuously move blood through an overabundance of vessels may become damaged

question

what is the risk for overweight people? what these people can do to make a difference? how this applies to body distribution of fat?

answer

-overweight people are more likely to develop heart disease and stroke even if they have no other risk factors -If you are heavy, losing even 5 to 10 pounds can make a significant difference -this is especially true if your are an "apple" (thicker around your upper body and waits) rather than "pear" (thicker around your hips and thighs)

question

_is a definite risk for CVD. how can solve this?

answer

-inactivity -the good news is that you do not have to be an exercise fanatic to reduce your risk. -Even modest level of low-intensity physical activity (walking, gardening, housework, dancing) are beneficial if done regularly and over the long term

answer

-Although Caucasians tend to have more heart disease, African Americans are 40% more likely to have hypertension and 10% less likely to have it under control and have a stroke -The rate of high blood pressure in African Americans is among the highest in the world -CVD risks are also higher among Hispanic/Latino Americans -Importantly, racial and ethnic minorities have a significantly greater risk of dying from CVD-relateed diseases

question

what ethnicity or race has more deaths of heart disease? stroke?

answer

-Caucasians or whites have highest heart disease deaths (25.1%) -African Americans have the highest percentage of deaths of strokes (4.0%) followed closely by Native Americans/Alaskan Native (3.9%) *summary of the percentages of total deaths for various ethnic groups by heart disease and stroke. include white/Caucasian, African American, Asian/Pacific Islander. Hispanic, Native American/Alaskan Native*

question

explain nonmodifiable risk of CVD: heredity

answer

-a family history of heart disease increases risk of CVD significantly -genetic link: amount of cholesterol produce, tendencies to form plaque, and a host of other factors -If you have close relatives with CVD, your risk may be double that of others

question

Is heart disease hereditary?

answer

-if there is a history of CVD in your family or your racial or ethnic background indicates a propensity for CVD, it is all the more important for you to have regular blood pressure and blood cholesterol screenings and for you to avoid lifestyle risks, including tobacco use, physical inactivity, and poor nutrition

question

what is difficult with the hereditary portion of nonmodifiable risks of CVD?

answer

-The difficulty comes in sorting out genetic influences from the modifiable factors shared by family members, such as environment, stress, dietary habits, and so on

question

nutrigenetics

-newer research has focused on studying the interactions between nutrition and genes -study the role that diet may play in increasing or decreasing risks among certain genetic profiles

question

explain the nonmodifiable risk of CVD: age

answer

-although cardiovascular disease can affect all ages, 75% of heart attacks occur in people over age 65. -Increasing age ups the risk for CVD for all

question

explain the nonmodifiable risk of CVD: Gender

answer

-men are at greater risk for CVD until about age 60, when women catch up and then surpass them -Otherwise healthy women under age 35 have a fairly low risk, although oral contraceptive use and smoking increase the risk -after menopause, or after estrogen levels are otherwise reduced (ex: because of hysterectomy) women's LDL levels tend to go up, which increases the chance for CVD

question

research suggest that _(sugar food) may reduce the risk of blood clots and improve blood flow in the brain

answer

research suggest that cocoa flavonols in chocolate may reduce the risk of blood clots and improve blood flow in the brain

question

list other risk factors that lead to increased risk of CVD (3)

answer

-inflammation and C-reactive protein -homocysteine levels -lipoportein(a)

question

many experts believe inflammation plays a major role in _development. how?

answer

-atherosclerosis development -it occurs when bacteria, trauma, toxins, or heat injure blood vessel walls, making them more prone to plaque formation

question

what have been linked to increased risk of inflammation? what is the greatest risk?

answer

-cigarette smoke, high blood pressure, high LDL cholesterol, diabetes, certain forms of arthritis, and exposure to toxins have all been linked to increased risk of inflammation -However, the greatest risk appears to be from certain infectious disease pathogens, most notably Chlamydia pneumoniae, a common cause of respiratory infections; Helicobacter pylori, a bacterium that causes ulcers; herpes simplex virus; and Cytomegalovirus, another herpes virus infecting most Americans before the age of 40

question

During inflammatory reaction, _tend to be present at high levels

answer

C-reactive proteins (CRPs)

question

presence of C-reactive proteins (CRPs) in the blood may signal elevated risk for_. how doctors can use this information?

answer

-angine pectoris and heart attack -doctors can test patients, and if CRP levels are high, action could be taken to prevent progression to a heart attack or other coronary event

question

homocysteine

answer

-an amino acid normally present in the blood

question

when homocysteine leads to increased risk of CVD? what specific types of CVD? why? (how similar to C-reactive proteins (CRPs))

answer

-high levels of homocysteine was a prelude to coronary heart disease, peripheral artery disease (PAD), and increased risk of stroke -scientists hypothesized that homocysteine works in much the same way as CRPs, inflaming the inner lining of the arterial walls and promoting fat deposits on the damaged walls and development of blood clots

question

high homocysteine levels are implicated in _(what other diseases)

answer

-declining cognitive functioning, Alzhemier's, and other condtiions

question

what was thought to reduce homocysteine levels in the body? what is the best thing to do?

answer

-When early studies indicated that folic acid and other B vitamins may help break down homocysteine in the body, food manufacturers responded by adding folic acids to a number of foods and touting the CVD benefits -However, the connection between homocysteine, folic acid, and cardiovascular disease is slowly unreaveling -Professional groups such as the American Heart Association do not currently recommend taking folic acid supplements to lower homocysteine levels and prevent CVD. Instead, they recommend a healthy diet as the best way to reduce risk

answer

-angiography

question

angiography (other name and definition)

answer

-also referred as cardiac catheterization -a technique for examining blockages in heart arteries

question

what is done in angiography?

answer

-a needle-thin tube called a catheter is threaded through heart arteries, a dye is injected, and an X ray is taken to discover which areas are blocked

question

atherectomy

answer

-a procedure that removes plaque

question

what drug can be used for heart attack prevention and reduction of harm form heart attack? what does? what people recommend and problems?

answer

-Aspirin has been touted for its blood-thinning qualities, although even its proponents recommend that only people of certain ages take it regular because of its possible side effects. Furthermore, once a patient has taken aspiring regularly for possible protection against CVD, stopping this regimen may, in fact, increase his or her risk

question

when a coronary artery is blocked, how long time passes for damage?

answer

-When a coronary artery is blocked, the heart muscle does not die immediately -Time determines how much damage occurs, and prompt action is vital

question

If a victim reaches an emergency room and is diagnosed fast enough of coronary artery that is blocked, what therapy can be used?

answer

-a form of clot-busting therapy called thrombolysis

question

thrombolysis

answer

-injection of an agent (such as tissue plasminogen activator (tPA)) to dissolve clots and restore some blood flow, thereby reducing the amount of tissue that dies from ischemia -these drugs must be administered within 1 to 3 hours after a heart attack for best results

answer

-smoke or smoking

question

role of HDL?

answer

"good" HDL cholesterol acts like a vacuum cleaner removing plaque.

question

Is the number one cause of death in the United States a) cancer or b) cardiovascular disease?

answer

The answer is A - Cardiovascular disease. Nearly 4 in every 10 American deaths is caused by it. The probability of dying from cardiovascular disease is twice as great as dying by cancer, the second leading cause.

question

Is the human heart a) the size of a golf ball or b) the size of a fist?

answer

The answer is b - It is the size of a fist.

question

Do a) veins or b) arteries carry blood from the heart to the body?

answer

The answer is A - arteries carry blood away from the heart, while veins carry deoxygenated blood back to it. Arteries branch into smaller arterioles and eventually into tiny capillaries.

question

A person whose sinoatrial node is damaged a) must have a pacemaker implanted to control the heart rhythm or b) requires an angioplasty.

answer

The answer is A - This person requires a pacemaker because the sinoatrial node functions as a natural pacemaker and initiates the electrical impulses that enable the heart to beat. When it fails to do this, the heart must be helped artificially.

question

The medical term for a "thickening" of arteries is a) atherosclerosis or b) angina pectoris.

answer

The answer is A - The condition is atherosclerosis, , also known as hardening of the arteries. Atherosclerosis is caused by a buildup of plaque (fats, cholesterol, fibrin, platelets and calcium) on the artery walls.

question

Ischemia is a) a squeezing of heart tissue causing damage or b) a reduced oxygen supply to the heart?

answer

The answer is B - It is a reduction of oxygen to the heart, and the same condition can lead to a stroke.

question

When one's heart races is he experiencing a) angina or b) tachycardia?

answer

The answer is B - Tachycardia, one of the arhythmias.

question

Which will reduce your risk for CVD? Is it a) quitting smoking or b) increasing your triglyceride level?

answer

The answer is A - Smoking is the #1 risk factor for CVD.

question

Patients with angina caused by arterial spasms may be treated with a) beta blockers or b) calcium channel blockers.

answer

The answer is B - calcium channel blockers, because calcium atoms passing through arteries can create spasms.

question

Which is a possible stroke symptom? Is it a) visual hallucinations or b) vision dimness?

answer

The answer is B - vision dimness.

question

Which ingredient in commercially-prepared baked foods can increase vulnerability to CVD? Is it a) saturated fats or b) transfats?

answer

The answer is B- less of a chance.

question

Are the signs of heart disease among women often neglected because a) heart disease among women is a new phenomenon or b) that doctors tend to view heart disease among men as a more serious problem?

answer

The answer is B.

question

Is it true or false that strokes can be caused by aneurysms?

answer

The answer is true - Strokes can be caused by aneurysms.

question

Streptococcal infections can lead to rheumatic fever, which in turn can cause rheumatic heart disease. True or False?

answer

The answer is true.

question

Men have more heart attacks but women die more often from heart attacks. True or False?

answer

The answer is true.

question

We can prevent heart disease if our levels of LDL cholesterol are high while our HDL cholesterol is low? True or False?

answer

The answer is false.

question

Taking 80 milligrams per day of low-dose aspirin may help prevent blood clotting. True or False?

answer

The answer is true.

question

at least _Americans die of sudden cardiac arrest each year

answer

400,000

question

what is happening to people with CVD problems and do a stress test? why? what Americans can do to prevent this?

answer

-people take stress test, pass them, and later have a massive heart attack -reason for this is the stress test only detect cholesterol build-up in the middle of the artery that impedes the blood supply. But when the artery wall is affected with cholesterol build-up and inflammation, this can lead to a sudden crack in the artery -ask doctor for inexpensive test, this protein that tracks with artery inflammation, which gives information well beyond what we can get with the stress test. These test can help find the hidden plaque inside the artery wall

question

where heart is located?

answer

located slightly left of center in your chest.

question

what is the function of the division between the left and right side of the heart? (atrioventricular septum)

answer

The division protects oxygen-rich blood from mixing with oxygen-poor blood

question

what comprises the cardiovascular system?

answer

your heart and blood vessels comprise your cardiovascular system

question

you heart pumps about _quarts of blood every minutes

answer

5 quarts of blood

question

flow of blood through cardiovascular system

answer

Oxygen-poor blood, "blue blood," returns to the heart after circulating through your body. The right side of the heart, composed of the right atrium and ventricle, collects and pumps blood to the lungs through the pulmonary arteries. The lungs refresh the blood with a new supply of oxygen, making it turn red. Oxygen-rich blood, "red blood," then enters the left side of the heart, composed of the left atrium and ventricle, and is pumped through the aorta to the body to supply tissues with oxygen.

question

what are the four valves of heart? function?

answer

Four valves within your heart keep your blood moving the right way. The tricuspid, mitral, pulmonary and aortic valves work like gates on a fence. They open only one way and only when pushed on. Each valve opens and closes once per heartbeat — or about once every second.

question

systole

answer

contraction of heart

question

diastole

answer

relaxation of heart

question

explain flow of blood through heart using systole and diastole

answer

During systole, your ventricles contract, forcing blood into the vessels going to your lungs and body — much like ketchup being forced out of a squeeze bottle. The right ventricle contracts a little bit before the left ventricle does. Your ventricles then relax during diastole and are filled with blood coming from the upper chambers, the left and right atria. Then the cycle starts over again.

question

your heart is nourished by blood too. what does this function?

answer

Blood vessels called coronary arteries extend over the surface of your heart and branch into smaller capillaries.

question

what keeps the heart beating? how flow of electricity flows? function of this system?

answer

-Your heart also has electrical wiring, which keeps it beating. Electrical impulses begin high in the right atrium and travel through specialized pathways to the ventricles, delivering the signal to pump. -The conduction system keeps your heart beating in a coordinated and normal rhythm, which in turn keeps blood circulating.

question

2 ways to measure blood pressure

answer

-It's done with a blood pressure monitor. There are two main types: manual, also called aneroid, and automatic. Automatic equipment contains electronics that sense the pulse wave under an inflated arm cuff. Automatic equipment minimizes human error and is recommended if you have hearing or vision loss.

question

what does a person's cholesterol levels indicate?

answer

the formation of fatty substances, called plaque, which can clog arteries

question

strategies to decrease chances of heart attack (lower hypertension)

answer

-decrease sodium -increase levels of exercise -practicing stress management/ control
