Highlights
Cardiovascular disease (CVD), including heart disease and stroke, was the number one killer of Georgians in 2003, accounting for 23,295 deaths, or 35% of all deaths.
The CVD death rate in Georgia was 12% higher than the national rate in 2003. For both men and women in Georgia, age-adjusted CVD death rates are higher for blacks than whites. In 2003, most CVD deaths in Georgia were classified as ischemic heart disease (41%) or stroke (18%). Georgia had the tenth highest CVD mortality rate among the 50 states in 2002; for stroke in particular, Georgia
had the ninth highest mortality rate among the 50 states. CVD caused more than 142,000 hospitalizations and $3.3 billion in hospital charges in 2003. 3 in 4 (74%) of Georgia adults have at least two modifiable risk factors for CVD. One in ten (9%) of Georgia adults
have 5 or more modifiable risk factors for CVD. The smoking rate among adults in Georgia has remained stable for the past decade; in 2003, one in four (23%)
reported that they currently smoked. CVD risk factors are frequently acquired before becoming adults. Data from youth surveys show high prevalence
of physical inactivity, poor diet, obesity, and smoking. The high CVD death rates should alert Georgians to the importance of working together to facilitate regular phys-
ical activity, healthy eating, and not smoking.

Introduction
Cardiovascular disease (CVD) includes all diseases of the heart and blood vessels, including ischemic heart disease, stroke, congestive heart failure, hypertensive disease, and atherosclerosis. CVD is the nation's leading killer of both men and women across all racial and ethnic groups. Each year in the United States, about 900,000 people die from CVD, which accounts for approximately 37% of all deaths.1,2 Over 6 million hospitalizations each year are due to CVD.1 According to the American Heart Association, CVD is a leading cause of disability in the nation.
In Georgia, CVD caused 23,295 deaths in 2003, 35% of all deaths that year (Figure 1, Table 1). Heart disease (all forms) and stroke are the first and third most common causes of death in Georgia (Figure 1). Ischemic heart disease - the most common form of heart disease - and stroke account for about 20% of deaths in Georgia (Table 1).
Death and disability from CVD are related to a number of risk factors, including smoking, inadequate physical activity, poor diet, obesity, high blood pressure, high cholesterol, and diabetes. The adoption of a healthier lifestyle can lower the risk of developing CVD or reduce the severity of existing disease.
This report describes the burden of CVD in Georgia and has the following purposes:
To present a brief overview of CVD death rates during the past two decades, including rates of ischemic heart disease and stroke
To report county-specific death rates
To report the number of CVD, ischemic heart disease, and stroke hospitalizations for Georgia residents
To describe the prevalence of CVD risk factors in Georgia and to describe the prevalence of secondary prevention measures in Georgia.

Cardiovascular disease death rates have declined in both Georgia and the U.S. during the past 23 years (Figure 2). The causes of the decline are presumably related to the decline in cigarette smoking during the 1980s, improved blood pressure control, populationwide reduction in blood cholesterol, and improvements in medical care.
From 1980 through 2003, the CVD death rate in Georgia declined by an average of 2.4% per year (Figure 2). Through the entire time period, Georgia's CVD death rate was consistently above the U.S. rate. Among the 50 states in 2002, Georgia had the tenth highest CVD death rate.
CVD death rates in Georgia differ by sex and race. The age-adjusted death rate from CVD was 1.4 times higher for males (411 per 100,000) than for females (292 per 100,000) in 2003. The age-adjusted death rate from CVD was 1.4 times higher for blacks (426 per 100,000) than for whites (325 per 100,000) in 2003. In 2003, the CVD death rate in Georgia was 1.3 times higher for black males than white males and 1.4 times higher for black females than white females (Figure 3). The reasons for higher rates among blacks are not well understood, but they may be a result of a higher percentage of blacks with high blood pressure, or a higher percentage living in poverty with associated factors of poor diet or decreased access to health care.
As stated above, males have a higher risk than females for dying from CVD. However, 11,038 males and 12,257 females in Georgia died from CVD in 2003. Since men experience CVD at a higher rate earlier in life, many people consider heart disease a "man's disease." Current health promotion campaigns are promoting awareness and education of the severity of CVD among women, the leading killer of women in Georgia.

CVD, however, is not just a disease of old age. The process of arterial narrowing, which causes heart attacks and strokes, may begin in the teenage years.3,4 The age at which blocked arteries actually kill varies greatly, and death can occur before old age. Of Georgians who died from CVD in 2003, 24% were younger than 65 years of age (Figure 4). A greater percentage of blacks than whites die from CVD at ages less than 65 years (Table 2). Almost one half (47%) of black men who died of CVD in 2003 were less than 65 years, whereas only 28% of white men who died of CVD were less than 65 years.
Georgia also has a large financial burden due to CVD. In 2003, CVD caused 142,000 hospitalizations resulting in $3.3 billion in hospital charges at acute care facilities.

Ischemic Heart Disease in Georgia
Ischemic heart disease, also known as coronary heart disease, refers to narrowing of the coronary arteries which reduces blood flow and oxygen to the heart. Ischemic heart disease includes acute myocardial infarctions ("heart attacks") and complications resulting from previous myocardial infarctions. Of the 23,295 cardiovascular deaths in Georgia in 2003, 9,579 (41%) were from ischemic heart disease. The death rate from ischemic heart disease has decreased during the past 23 years at an average decline of 3.5% per year (Figure 5). Unlike total cardiovascular disease, Georgia's death rate from ischemic heart disease is below the national rate, ranging from 5% to 14% below the US rate each year (Figure 5).
In Georgia, the age-adjusted death rate from ischemic heart disease was 1.8 times higher for men (192 per 100,000) than for women (105 per 100,000) in 2003. The age-adjusted death rate from ischemic heart disease was similar for blacks (147 per 100,000) and whites (141 per 100,000) in 2003. Among men, whites had a slightly higher age-adjusted death rate than blacks; whereas among women, blacks had a slightly higher age-adjusted death rate than whites (Figure 6). Similar to overall CVD, the death rate from ischemic heart disease increases with age, but 26% of deaths in 2003 occurred in persons less than 65 years old.

Stroke in Georgia
Stroke, sometimes called cerebrovascular disease, refers to an infarct (loss of blood supply due to a blocked artery) or hemorrhage in the brain. Of the 23,295 CVD deaths in Georgia in 2003, 4,285 (18%) were due to stroke. Age-adjusted death rates from stroke have decreased during the past 23 years in both Georgia and the US (Figure 7); however since 1992, the rate of decline has slowed. In Georgia, the stroke death rate decreased an average of 4.4% per year from 1980 to 1992 but only decreased 1.2% per year from 1992 to 2003. Age-adjusted stroke death rates in Georgia are consistently above the US rate although the gap is narrowing, with Georgia's rate 32% above the US rate in 1980 but only 20% above the US rate in 2003.
Unlike ischemic heart disease deaths, for which sex differences are more striking than racial differences, ageadjusted stroke deaths are much higher for blacks than whites. In Georgia, the age-adjusted death rates from stroke were similar for men (65 per 100,000) and women (63 per 100,000) in 2003. The age-adjusted death rate from stroke was 1.5 times higher for blacks (88 per 100,000) than for whites (58 per 100,000) in 2003. Reasons for the difference are not well understood but may include the higher prevalence of high blood pressure and decreased access to health care among blacks. Black males had a higher age-adjusted death rate from stroke than black females, but the rates for white males and white females were almost the same in 2003 (Figure 8).
As for most other types of cardiovascular disease, the stroke mortality rate increases with age. Nonetheless, 19% of persons dying from stroke in Georgia in 2003 were less than 65 years old.

Cardiovascular Disease Statistics by County
Figure 9 (map) shows average annual age-adjusted CVD deaths rates by county during the period 1999 through 2003. Counties with the highest CVD death rates are clustered in the southeast region and along the state's western border. Figure 10 (map) shows average annual age-adjusted stroke death rates by county during 1999-2003, with the lowest rates in the counties surrounding Atlanta.
Tables 3 and 4 (pages 10-17) show the following data for Georgia counties and public health districts respectively: the number of CVD deaths in 2003, the average annual age-adjusted mortality rate for CVD from 1999 to 2003, the number of stroke deaths and the corresponding age-adjusted rate, and the number of ischemic heart disease deaths and the corresponding age-adjusted rate. Average annual age-adjusted mortality rates were calculated for a 5-year period because counties with small populations had too few deaths to calculate a stable rate accurately for a shorter time period. Caution should be used when making comparisons
among age-adjusted county death rates because counties with small populations are more likely to have wide variations in rates from year to year simply because of chance.
The right-hand set of columns in Tables 3 and 4 shows the total charges for CVD hospitalizations in 2003, the 2003 CVD hospitalization rate, the number of hospitalizations for CVD in 2003, and the number of hospitalizations for stroke, ischemic heart disease, and congestive heart failure. Hospitalization data are based on county of residence, not location of hospital. Furthermore, the data are restricted to acute care, nonfederal facilities, which excludes patients seen at Veteran's Administration and military facilities. Caution should be used when making comparisons among counties because Georgia residents hospitalized outside of Georgia are not included in the tables. This may lead to an underestimation of hospitalizations for residents of counties near large cities in neighboring states (e.g. counties bordering Chattanooga, TN, or Jacksonville, FL).

Cardiovascular Disease Risk Factors
Some CVD risk factors are modifiable, meaning that individuals can change their behavior to prevent, slow, or even reverse, the process of arterial blockage and decrease their risk of having a heart attack or stroke. Modifiable risk factors among adults include smoking, inadequate physical activity, poor diet, obesity, high blood pressure, high blood cholesterol level, and diabetes (Figure 11). Risk factors for CVD are not present exclusively among adults; many youth in Georgia adopt unhealthy habits early in life which contribute to the risk of heart disease (Figure 12).
Some CVD risk factors cannot be changed, such as old age, male sex, and family history of heart attacks at a young age. Individuals with non-modifiable risk factors should be particularly diligent in eliminating modifiable risk factors.
SMOKING
The percentage of Georgia adults who currently smoke declined from 31% in 1984 to 19% in 1992; since then, the percentage of adults who smoke has been consistently higher than 20% (Figure 13). In 2003, 23% of Georgia adults reported that they currently smoke cigarettes (Figure 11).
Lowering smoking rates is a public health priority. In addition to its well-known association with cancer, smoking is a major risk factor for CVD. Each year in Georgia smoking causes almost the same number of deaths from CVD as cancer, 4,226 and 4,235 deaths, respectively.5 The good news is that giving up smoking quickly reduces the risk for CVD.6 It is also important to prevent people, especially young people, from initiating smoking. Eighty percent of tobacco-users begin before their eighteenth birthday. If adolescents are kept tobacco-free, most will never start smoking.7 In 2003, 21% of Georgia high school students were current smokers. This rate is similar to the rate in adults (Figure 12).
As of July 2005, the Georgia Smoke Free Air Act prohibits smoking in workplaces and public establishments. The new restrictions will reduce exposure to secondhand smoke and limit public venues for current smokers.
PHYSICAL INACTIVITY, DIET AND OBESITY
Regular, moderate, or vigorous physical activity can reduce the risk for CVD.8 CDC recommendations are 30 minutes, 5 days a week of moderate physical activity or 20 minutes, 3 days a week of vigorous physical activity. Fifty-eight percent of Georgia adults and 37% of Georgia high school students do not meet the CDC's recommended level of physical activity (Figures 11, 12). Forty-two percent of Georgia high school students reported watching at least 3 hours of TV per day in 2003 (Figure 12).
Eating five or more servings of fruits or vegetables per day can help prevent heart disease, cancer, and other chronic conditions. In 2003, only 23% of Georgia adults reported that they ate at least five servings of fruits and vegetables per day (Figure 11). Only 17% of Georgia high school students report eating at least 5 daily servings of fruits and vegetables (Figure 12).
18
Obese adults are at increased risk for CVD.9 In both Georgia and the US, there has been a steady increase in the percentage of obese adults (body mass index greater than 30.0; see appendix for details). The percent of obese adults in Georgia was 25% in 2003 (Figure 11). Eleven percent of Georgia high school students were obese in 2003 (Figure 12).
HIGH BLOOD PRESSURE
High blood pressure is a major risk factor for both heart disease and stroke. The percentage of Georgians who reported having been told they had high blood pressure was 28% in 2003 (Figure 11). The percentage of Georgians with high blood pressure whose blood pressure is currently under control is not known. Nationally, only 69% of people with high blood pressure know it. Of those, 58% are treated with medications, and of those, 53% are controlled on medications. Only 31% of people with high blood pressure have it adequately controlled.10 For some people, high blood pressure can be controlled by losing weight and engaging in regular physical activity. Those who are unable to decrease their blood pressure by lifestyle modification alone require medications prescribed by a physician to successfully control high blood pressure.

HIGH CHOLESTEROL
When there is too much cholesterol in blood, the excess can become trapped in the artery walls, gradually narrowing and damaging the arteries and increasing the risk of heart attack or stroke. Cholesterol is transported to and from cells by lipoproteins. Low-density lipoprotein (LDL), the "bad cholesterol," clogs the arteries; a high level of LDL increases the risk for heart disease. High-density lipoprotein (HDL), the "good cholesterol," removes cholesterol from the arteries; a high level of HDL decreases the risk for heart disease. A high total cholesterol level increases the risk for heart disease. Lowering high total blood cholesterol levels can decrease the risk of death from heart disease.11
The percentage of Georgian adults who report ever having had their blood cholesterol level checked increased from 53% in 1987 to 75% in 2003. Of persons who had
been checked, the percentage told that they have high cholesterol increased from 15% in 1987 to 33% in 2003 (Figure 11). It is not known if the increase in the percentage of persons reporting high cholesterol represents a true increase in cholesterol levels among Georgians. Other explanations for the increase may include increased screening among high risk populations.
Many people can control their cholesterol level by modifying their diet. For those who cannot, medication can lower blood cholesterol levels. In adults, a total cholesterol level of 200 mg/dL or higher is considered elevated; LDL levels >130 mg/dL or HDL levels <40mg/dL also increases a person's risk of CVD.10 The National Institutes of Health recommend that all adults get a fasting lipoprotein profile (total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides) every 5 years.11
20
DIABETES
Persons with diabetes have two to three times the risk of death from cardiovascular disease as persons who do not have diabetes.12 The prevalence of diabetes among adults has increased nationwide during the past decade.13 Among children, the prevalence of diabetes has increased, due to an increase in type 2 diabetes, which is associated with obesity.14 In Georgia, the prevalence of diabetes among adults increased from 4% in 1993 to 8% in 2003 (Figure 11). Similar data are not available for children. Maintaining healthy body weight and staying physically active can prevent type 2 diabetes. Persons with diabetes can prevent complications by keeping their blood sugar as close to normal as possible, refraining from smoking, eating a healthy diet, getting regular physical activity, and maintaining normal blood pressure.
MULTIPLE RISK FACTORS
Since risk factors work in combination to increase risk, it is important to consider multiple risk factors. Of the seven major modifiable risk factors, 74% of Georgia adults have at least two. Approximately 9% of Georgians have 5 or more risk factors. Only 6% of Georgia adults live with no major modifiable CVD risk factors (Table 5).
The majority of individuals in high risk groups do not discuss appropriate behavior modifications with medical professionals. In high-risk populations, fewer than half received medical advice regarding adopting healthier lifestyles (Table 6). In addition to conducting a personalized risk assessment, a medical professional can provide counseling or direct individuals to resources to aid in the modification of risk factors.

Secondary Prevention of CVD
Secondary prevention involves efforts to further reduce risk among individuals who have already experienced a CVD event. In 2003, approximately 8% of Georgia adults reported a previous heart attack, ischemic heart disease, or a stroke (Figure 14). For individuals with a history of a previous CVD event, the risk for a subsequent event is substantial.15 It is important for these individuals to take steps to prevent a recurrence.
There is a strong association between modifiable risk factors and a history of CVD event. The percentage of persons experiencing a CVD event was higher among people who had several modifiable risk factors. Three quarters of persons reporting 7 modifiable risk factors had a history of CVD, whereas only 2% of persons with no modifiable risk factors had a history of CVD (Figure 15).
Cardiac rehabilitation was utilized by 26% of Georgia adults who had reported past heart attack or stroke during 2003. The American Heart Association defines cardiac rehabilitation as coordinated, multifaceted interventions designed to optimize a cardiac patient's physical, psychological, and social functioning, in addition to stabilizing, slowing, or even reversing the progression of the underlying atherosclerotic processes, thereby reducing morbidity and mortality. These comprehensive and long-term programs often involve baseline patient assessment, nutritional counseling, aggressive risk factor management, counseling, and exercise training. Exercise-based cardiac rehabilitation is associated with lower total and cardiac mortality rates when compared to usual medical care.16
The American Heart Association recommends consideration of the use of aspirin for persons who have had a heart attack, unstable angina, ischemic stroke or transient ischemic attack.17 For certain types of heart conditions, other medications may be useful in reducing the risk of recurrence.
The majority of Georgia adults were able to correctly identify the major symptoms of heart attack and stroke (Table 7). Early recognition of CVD events can expedite treatment and reduce complications and severity. The CDC estimates that 60% of cardiac deaths occur either before reaching a hospital or in the emergency room.18
The Georgia Coverdell Stroke Registry (GCSR) was established in 2005 to improve the care of acute stroke patients in hospital settings. This program addresses quality improvement in multiple areas of stroke care, from rapid screening, diagnosis, and intervention for patients experiencing an acute stroke, to secondary prevention measures such as blood pressure control, smoking cessation, and treatment of elevated cholesterol in order to reduce the incidence of recurrent stroke after hospital discharge. In addition, the program will also help improve the utilization of rehabilitation services for those who have experienced an acute stroke in the an effort to reduce long-term disability due to stroke. The GCSR is a component of the state of Georgia Cardiovascular Health Initiative, which is a part of a national effort funded by the CDC to reduce heart disease and stroke related morbidity and mortality.

Conclusions
This report summarizes the most recent information available on cardiovascular disease deaths and hospitalizations in Georgia. The burden of cardiovascular disease in Georgia is immense. CVD is the leading cause of death in Georgia, resulting in over 142,000 hospitalizations and charges of $3.3 billion in 2003. Annual CVD medical charges have increased over time and will likely continue to increase with rising healthcare costs, advances in medical care, aging population, and escalating risk factor prevalence. The burden of CVD is greater among particular populations. Blacks have higher rates of CVD than whites, especially for stroke. Furthermore, men have higher rates of CVD than women. The practical implications of these findings are clear. Because most heart attacks and strokes result from a process of arterial blockage that begins at an early age, a greater effort should be made to reduce the prevalence of risk factors among all Georgians, including children and adolescents. Reducing CVD risk factors involves not smoking, engaging in regular physical activity, eating a healthy diet, maintaining a healthy weight, controlling high blood pressure, reducing blood cholesterol, and preventing diabetes. Sustained behavioral changes are often difficult to make, even for highly motivated individuals. Therefore, it is critical that entire communities make policy and environmental changes that make it easier for individuals to change their behavior. Community leaders and parents can act as role models. Additionally, local environments, such as schools and workplaces, can implement policies that facilitate healthy behaviors. Some changes in the environment include 100% tobacco-free policies, opportunity for physical activity during the work day, and healthy vending machine and cafeteria choices. Much of the death and disability from CVD in Georgia is preventable. If we focus attention on realistic ways of reducing risk, we can continue the decline in CVD death rates that Georgia has experienced in much of the past two decades. Georgians can work together to reduce the number of individuals who suffer and die from cardiovascular disease by advocating for healthier communities and following treatment recommendations. As we move forward it is imperative that we encourage everyone in our state to "Live Healthy."

METHODS
Age-adjusted mortality rates for the US from 1980 through 1998 and for Georgia from 1980 though 1993 were obtained via WONDER at http://wonder.cdc.gov from the compressed mortality file compiled by the National Center for Health Statistics, CDC. Age-adjusted mortality rates for Georgia from 1994 though 1998 were obtained from OASIS at http://oasis.state.ga.us. The following ICD-9 codes were used: CVD, 390-434, 436-448; ischemic heart disease, 410-414, 429.2; and stroke, 430-434, 436-438. The 2000 U.S. standard population was used as the standard population.
Age-adjusted mortality rates for the US from 1999 through 2002 were obtained via WONDER at http://wonder.cdc.gov from the compressed mortality file compiled by the National Center for Health Statistics, CDC. Age-adjusted mortality rates for Georgia from 1999 though 2003 were obtained from OASIS at http://oasis.state.ga.us. The following ICD-10 codes were used for CVD: CVD, I00-78; ischemic heart disease, I20-25; stroke, I60-69; heart failure, I50; other CVD, CVD codes not already categorized. ICD-10 codes for stroke included subarachnoid hemorrhage, I60; other cerebral hemorrhage, I61-62; occlusion, I63; acute ill-defined, I64; other ill-defined, I67; sequelae, I69. ICD-10 codes for non-CVD causes of death included cancer, C00-C97; chronic respiratory disease, J40-J47; unintentional injuries, V01-X59, Y85-86; diabetes, E10-14; Alzheimers, G30; kidney disease, N00-07, N17-19, N2527; influenza and pneumonia, J10-18. Age-adjusted death rates for Georgia were calculated using the direct method with population estimates from the U.S. Bureau of the Census (release date: August 30, 2000) and the 2000 U.S. standard population as the standard. Age-adjusted death rates for the US in 2003 were obtained from the National Vital Statistics Report, Vol 53, No. 15, February 28, 2005.
The average annual percentage change in age-adjusted death rates represents the average of the relative change between each pair of consecutive years.
Data on hospitalizations at acute care hospitals in Georgia were provided by the Office of Health Information and Policy after compilation by the Georgia Hospital Association. Analyses were restricted to Georgia residents. The following ICD-9-CM codes were used for principal diagnosis: CVD, 390-448; ischemic heart disease, 410-414; stroke, 430-438; heart failure, 428; hypertensive disease, 401-404; atherosclerosis, 440.
Age-adjusted mortality rates for counties and districts were calculated using data from death certificates provided by Vital Statistics Branch and Office of Health Information and Policy. The number of deaths for 1999 through 2003 was determined using the ICD-10 codes above (CVD, I00-78; ischemic heart disease, I20-25; stroke, I60-69). Age-adjusted mortality rates were calculated using county population estimates from the US Bureau of Census and the year 2000 U.S. standard population as the standard. The z-test was used to compare county rates to the state rate with significance at p<0.05. The source of the formula for the z-test and the standard error for an age-adjusted rate was the National Center for Health Statistics, National Vital Statistics Report, volume 48, number 11, July 24, 2000, page 104.
Data on behaviors, health history, and health knowledge among adults were obtained from the 2003 Georgia Behavioral Risk Factor Surveillance System, a telephone survey conducted annually with a sample of adults aged 18 years and older.19 The sample is weighted so that it reflects the total adult population of the state. Data for Table 6 were obtained from module 9, "Cardiovascular Disease." Data for heart attack and stroke symptoms were obtained from module 8, "Heart Attack and Stroke." CVD risk factors assessed by the BRFSS include the following:
Current smoker: Defined as someone who has smoked at least 100 cigarettes in his lifetime and smokes now.
High blood pressure: Defined as ever having been told by a doctor, nurse, or health professional that your blood pressure was high.
High cholesterol: Defined as ever having been told by a doctor or health professional that your blood cholesterol level was high.

Physical activity recommendations: 30 minutes, 5 days a week (moderate physical activity) or 20 minutes, 3 days a week (vigorous physical activity). Obese: Defined as a body mass index [BMI] > 30.0 kilograms per meter squared, based on self-reported height and weight. BMI equals weight (in kilograms) divided by height (in meters) squared. Using weight (in pounds) and height (in inches), BMI equals 705 times weight divided by height squared. Daily servings of fruits and vegetables: Number of servings of fruits or vegetables per day based on self-reporting of consumption during the past day, week, month, or year. Diabetes: Defined as ever having been told by a doctor that you have diabetes. Previous cardiovascular disease: Defined as ever having been told by a doctor that you had a heart attack and/or myocardial infarction, angina and/or coronary heart disease, or a stroke. Prevalence data on CVD risk factors among high school students were obtained from the 2003 Georgia Student Health Survey (GSHS) conducted by the Georgia Department of Human Resources, Division of Public Health, in collaboration with the Georgia Department of Education.20 The questionnaire was modeled after the core Youth Risk Behavior Survey, developed by the Centers for Disease Control. Each student record is weighted so that it reflects the likelihood of sampling each student. CVD risk factors assessed by the GSHS are defined according to the above BRFSS terms, except: Current Smoker: Defined as smoking cigarettes on one or more of the past 30 days. Daily servings of fruits and vegetables: Number of servings of fuits or vegetables per day in the past 7 days. Obese: Body mass index for age 95th percentile, based on self-reported height and weight. TV Watching: Hours of TV watched per day on an average school day.
GLOSSARY Age-adjusted death rate: a rate calculated based on a standard age distribution to enable comparison of rates in populations with different age structures Angina: pain or discomfort in the chest that occurs when the heart does not receive enough blood Atherosclerosis: deposits of cholesterol and other substances in the walls of arteries Cardiovascular disease: includes a wide variety of diseases of the heart and blood vessels, including ischemic heart disease (heart attacks), high blood pressure, stroke, and hypertensive heart disease. Cholesterol: fatty substance in blood that gets deposited in blood vessel walls, causing atherosclerosis, when blood cholesterol levels are high HDL (high-density lipoprotein): carries cholesterol away from other parts of the body back to the liver for removal from the body Heart attack (also known as myocardial infarction): death or damage to the heart muscle caused by an insufficient supply of oxygen due to blockage of one or more coronary arteries Heart failure: condition in which the heart cannot pump enough blood to meet the body's needs Hospital charges: a hospital's full established rates, which do not necessarily reflect costs or reimbursement
27
Ischemic heart disease(also known as coronary heart disease): includes heart attacks and related problems caused by a narrowing of the coronary arteries LDL (low-density lipoprotein): contains most of the cholesterol in the blood and carries it to tissues and organs via arteries; it is the main source of damaging buildup and blockage in the arteries Modifiable Risk Factor: a risk factor that can be changed in order to slow, or reverse, the disease process and decrease the risk of disease Prevalence: the percentage of a population that has a disease or a risk factor at a specific point in time Risk factor: a habit, characteristic, or finding on clinical examination that is associated with an increased probability of a disease Stroke: occurs when blood vessels to the brain burst or become clogged by a blood clot or some other particle resulting in lack of blood flow and oxygen to the brain and death of brain cells
