2 Copyright © 2011 Pearson Education, Inc. Cardiovascular Disease: An Epidemiological Overview  Cardiovascular Disease (CVD) Cardiovascular disease is the cause of 37 percent of all deaths in the United States. For all ages combined, CVD is the leading cause of death. More than 80 million Americans—1 out of every 3 adults—will have some type of CVD. The best defense against CVD is to prevent it from developing in the first place.  Do you know someone who has had a heart problem?

4 Copyright © 2011 Pearson Education, Inc. Understanding the Cardiovascular System  The Heart: A Mighty Machine Four chambers Two upper chambers are called atria Two lower chambers are called ventricles Valves regulate the flow of blood.

6 Copyright © 2011 Pearson Education, Inc. Understanding the Cardiovascular System  Heart Function Deoxygenated blood enters the right atrium From the right atrium, blood travels to the right ventricle Blood is pumped through the pulmonary artery to the lungs, where it receives oxygen Oxygenated blood from the lungs returns to the left atrium of heart Blood from the left atrium moves into the left ventricle The left ventricle pumps blood through the aorta to all body parts

8 Copyright © 2011 Pearson Education, Inc. Cardiovascular Disease  Atherosclerosis (CAD— coronary artery disease) Arteriosclerosis Hyperlipidemia Inflammatory risk Peripheral artery disease (PAD)  Coronary Heart Disease (CHD) Greatest killer Myocardial infarction (MI) or heart attack

10 Copyright © 2011 Pearson Education, Inc. Cardiovascular Disease  Angina Pectoris Ischemia—condition that reduces the heart’s blood and oxygen supply People with ischemia often suffer angina pectoris, or chest pain and pressure. Treatments include calcium channel blockers or beta- blockers  Arrhythmias Irregularity in heart rhythm Fibrillation Over 4 million Americans have experienced some type of arrhythmia

11 Copyright © 2011 Pearson Education, Inc. Cardiovascular Disease  Congestive Heart Failure (CHF) Affects over 5 million Americans Single most frequent cause of hospitalization in United States  Stroke 6.5 million Americans suffer strokes every year Blood supply to brain is interrupted Transient ischemic attacks (TIAs) are brief interruptions of the blood supply to the brain that cause temporary impairment. Today, stroke is a leading cause of serious long-term disability and contributes a significant amount to Medicaid and Medicare expenses for older Americans, particularly women.

12 Copyright © 2011 Pearson Education, Inc. ABC News Video: Heart Disease in America Discussion Questions 1.What preventive measures can be taken to avoid a heart attack? 2.What effect does a celebrity death from a certain illness have on how members of the public address their own health? | Heart Disease in America

13 Copyright © 2011 Pearson Education, Inc. Reducing Your Risks  Metabolic Syndrome: Quick Risk Profile For a diagnosis of metabolic syndrome, a person would have three or more of the following risks: Abdominal obesity Elevated blood fat (triglycerides greater than 150 units) Low levels of HDL (“good”) cholesterol Elevated blood pressure greater than 130/85 mm/Hg Elevated fasting glucose greater than 100 mg/dL High levels of C-reactive proteins

14 Copyright © 2011 Pearson Education, Inc. Reducing Your Risks  Modifiable Risks Avoid tobacco. Cut back on saturated fats and cholesterol. Low-density lipoproteins (LDL) High-density lipoproteins (HDL) Triglycerides Maintain a healthy weight. Exercise regularly. Control diabetes. Control blood pressure. Manage stress.

17 Copyright © 2011 Pearson Education, Inc. Reducing Your Risks  Nonmodifiable Risks Race and ethnicity Heredity Age Gender  Other Risk Factors Being Studied Inflammation and C-reactive protein Homocysteine

18 Copyright © 2011 Pearson Education, Inc. Weapons against Cardiovascular Disease  Techniques for Diagnosing Cardiovascular Disease Electrocardiogram (ECG) Angiography Positron emission tomography (PET) scan Magnetic resonance imaging (MRI) Ultrafast computed tomography (CT) scan Cardiac calcium score

19 Copyright © 2011 Pearson Education, Inc. Weapons Against Cardiovascular Disease  Bypass Surgery and Angioplasty Coronary bypass surgery helps patients who suffer from coronary blockages of heart attacks. In bypass surgery, a blood vessel is taken from another site in the patient’s body and implanted to “bypass” blocked coronary arteries. Angioplasty uses a balloon to open the artery to allow blood to flow more freely. Angioplasty carries fewer risks and may be more effective in selected cases than bypass surgery.

20 Copyright © 2011 Pearson Education, Inc. Weapons against Cardiovascular Disease  Can Aspirin Help Heart Disease? Low doses of aspirin (75 to 81 mg) daily or every other day can be beneficial to heart patients Blood-thinning properties Risks may outweigh the benefits

21 Copyright © 2011 Pearson Education, Inc. An Overview of Cancer Second leading cause of death in the United States 1.5 million new cases diagnosed every year Early detection and improvements in technology have improved prognosis for many.  Why do you think the rate of cancer is so high in the U.S. today?

22 Copyright © 2011 Pearson Education, Inc. An Overview of Cancer  What Is Cancer? Uncontrolled growth and spread of abnormal cells Neoplasms Malignant tumors Benign tumors

23 Copyright © 2011 Pearson Education, Inc. Metastasis

24 Copyright © 2011 Pearson Education, Inc. What Causes Cancer?  Lifestyle Risks Tobacco use Poor nutrition, physical inactivity, and obesity Stress and psychosocial risks  Genetic and Physiological Risks Genetic predisposition Oncogenes—cancer-causing gene that typically stays dormant but can be activated Biological sex Reproductive and hormonal risks

26 Copyright © 2011 Pearson Education, Inc. What Causes Cancer?  Occupational and Environmental Risks Exposure to asbestos, nickel, chromate, and benzene Exposure to radioactive substances Chemicals in foods Medical treatment risks  Infectious Diseases and Cancer Hepatitis B and hepatitis C Liver cancer Human papillomavirus and cervical cancer
