2 Lesson 1 Cardiovascular Diseases Why should you establish and maintain healthful habits to care for your heart?

3 Lesson 1 In this lesson, you will learn to: Lesson Objectives Describe the types of cardiovascular diseases Discuss the importance of early detection Identify risk behaviors and risk factors for cardiovascular diseases Develop strategies related to the prevention of noncommunicable diseases

4 Lesson 1 A century ago, communicable diseases were a leading cause of death in the United States. Today, however, major causes of death, such as heart disease and cancer, come from noncommunicable diseases.noncommunicable diseases Communicable and Noncommunicable Diseases Cardiovascular Diseases

5 Lesson 1 Your cardiovascular system transports blood to all parts of your body. Without oxygen and other materials that blood carries, your cells would die. Sometimes diseases interfere with the pumping action of the heart or the movement of blood through blood vessels. Cardiovascular diseases (CVDs) are responsible for more than 40 percent of all deaths in the United States, killing almost a million Americans each year.Cardiovascular diseases (CVDs) What Are Cardiovascular Diseases? Cardiovascular Diseases

6 Lesson 1 Ways to Avoid Risk of CVD Avoid tobacco. Get plenty of physical activity. Maintain a healthful weight. Follow an eating plan that is low in saturated fat, cholesterol, and sodium. Cardiovascular Diseases

7 Lesson 1 Diseases of the Heart, Blood, and Blood Vessels Types of Cardiovascular Disease Hypertension Atherosclerosis Angina Pectoris Arrhythmias Heart Attack Congestive Heart Failure Stroke

8 Lesson 1 Hypertension Hypertension is a major risk factor for other types of CVDs.Hypertension Hypertension can occur at any age, but it is more common among people over the age of 35. High blood pressure can be lowered with strategies such as medication, weight management, adequate physical activity, and proper nutrition. Types of Cardiovascular Disease

9 Lesson 1 Atherosclerosis At birth, the lining of blood vessels is smooth and elastic. Over time, factors such as tobacco smoke, high blood pressure, and high cholesterol levels can damage the inner lining of the arteries. Atherosclerosis causes the arteries to thicken and lose their elasticity.Atherosclerosis It is caused mainly due to food choices—specifically, a high intake of saturated fats and cholesterol. Types of Cardiovascular Disease

10 Lesson 1 Diseases of the Heart Your heart pumps about 100,000 times a day every day to move blood to all parts of your body. Just like every other organ, your heart needs the oxygen from blood to function. When the blood supply to the heart is insufficient to provide enough oxygen, the result can be pain, damage to the heart muscle, or even sudden death. Types of Cardiovascular Disease

11 Lesson 1 Diagnostic Tools Types of Cardiovascular Disease

12 Lesson 1 Treatment Options Types of Cardiovascular Disease

13 Lesson 1 Angina Pectoris Angina pectoris, which usually lasts from a few seconds to minutes, is a warning sign that the heart is temporarily not getting enough blood.Angina pectoris The most common cause of angina is atherosclerosis. Angina seldom causes permanent heart damage and sometimes can be treated with medication. Types of Cardiovascular Disease

14 Lesson 1 Arrhythmias Arrhythmias occur in millions of people who do not have underlying heart disease, and they usually don’t cause problems.Arrhythmias In one type of arrhythmia, called ventricular fibrillation, the electrical impulses regulating heart rhythm become rapid or irregular. This is the most common cause of sudden cardiac arrest, in which the heart stops beating without warning. Without immediate emergency help, death follows within minutes. Types of Cardiovascular Disease

15 Lesson 1 Heart Attack A heart attack is damage to the heart muscle caused by a reduced or blocked blood supply. Many heart attacks are sudden and cause intense chest pain, but one in four produces no symptoms and is detected only when routine tests are done later. Types of Cardiovascular Disease

16 Lesson 1 Congestive Heart Failure A heart attack is an immediate response to stress on the heart. Sometimes, however, the heart gradually weakens to the point that it cannot maintain its regular pumping rate and force. The result is a condition called congestive heart failure. Strategies for managing congestive heart failure include medication and the establishment of healthy lifestyle behaviors, such as a good nutrition and adequate physical activity. Types of Cardiovascular Disease

17 Lesson 1 Stroke When arterial blockage interrupts the flow of blood to the brain, a stroke may occur. Stroke can affect different parts of the body, depending on the part of the brain that is deprived of oxygen. It can also occur as a result of a cerebral hemorrhage, a condition in which a blood vessel in the brain bursts, causing blood to spread into surrounding brain tissue. Types of Cardiovascular Disease

18 Lesson 1 Why Teens Are at Risk The behaviors established during your teen years and early adult life determine, in large part, your risk of developing CVD. Autopsy results of adolescents who died from causes other than CVD have revealed that one in six already had evidence of CVD. Those who had a history of known risk factors, such as smoking or diabetes, were more likely to have blood-vessel damage. Types of Cardiovascular Disease

19 Lesson 1 Risk Factors for Cardiovascular Disease Factors That You Can Control Factors That You Cannot Control Heredity Gender Age Tobacco use High blood pressure High cholesterol Physical inactivity Excess weight Stress Drug and alcohol use Types of Cardiovascular Disease

20 Lesson 1 Choose the appropriate option. Q. Chest pain that results when the heart doesn’t get enough oxygen is called _______. 1.arrhythmia 2.atherosclerosis 3.hypertension 4.angina pectoris Quick Review

21 Lesson 1 Click Next to attempt another question. A. 4. angina pectoris Chest pain that results when the heart doesn’t get enough oxygen is called angina pectoris. Quick Review - Answer

22 Lesson 1 Quick Review True False Choose the appropriate option. Q. Atherosclerosis is the process in which plaques accumulate on artery walls. The clots that form in the plaques can block the arteries leading to the heart, causing a heart attack.
