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

3 Lesson 1 In this lesson, youll learn to: Lesson Objectives Examine different types of cardiovascular diseases. Recognize the importance of early detection and warning signs that prompt individuals of all ages to seek health care. Identify risk behaviors and risk factors for cardiovascular diseases. Develop, analyze, and apply strategies related to the prevention of noncommunicable diseases such as cardiovascular disease.

4 Lesson 1 Cardiovascular Diseases 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

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)Cardiovascular diseases (CVDs) are responsible for more than 40 percent of all deaths in the United States, killing almost a million Americans each year. What Are Cardiovascular Diseases? Cardiovascular Diseases

6 Lesson 1 Cardiovascular Diseases 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.

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 Types of Cardiovascular Disease HypertensionHypertension is a major risk factor for other types of CVDs. 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.

9 Lesson 1 Atherosclerosis Types of Cardiovascular Disease 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. AtherosclerosisAtherosclerosis causes the arteries to thicken and lose their elasticity. It is caused mainly due to food choicesspecifically, a high intake of saturated fats and cholesterol.

10 Lesson 1 Diseases of the Heart Types of Cardiovascular Disease 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.

11 Lesson 1 Diagnostic Tools Types of Cardiovascular Disease

12 Lesson 1 Treatment Options Types of Cardiovascular Disease

13 Lesson 1 Types of Cardiovascular Disease Angina Pectoris 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. The most common cause of angina is atherosclerosis. Angina seldom causes permanent heart damage and sometimes can be treated with medication.

14 Lesson 1 Types of Cardiovascular Disease Arrhythmias Arrhythmias occur in millions of people who do not have underlying heart disease, and they usually dont cause problems. 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.

15 Lesson 1 Types of Cardiovascular Disease 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.

16 Lesson 1 Types of Cardiovascular Disease 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.

17 Lesson 1 Types of Cardiovascular Disease 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.

18 Lesson 1 Types of Cardiovascular Disease 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.

20 Lesson 1 Choose the appropriate option. Q. Chest pain that results when the heart doesnt 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. Chest pain that results when the heart doesnt get enough oxygen is called angina pectoris. Quick Review - Answer

22 Lesson 1 Quick Review Provide a short answer to the question given below. Click Next to view the answer. Q. What is atherosclerosis? How does it contribute to heart attacks?

23 Lesson 1 A. 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. Click Next to attempt another question. Quick Review - Answer

24 Lesson 1 Provide a short answer to the question given below. Click Next to view the answer. Q. Define cardiovascular disease. How does regular physical activity help prevent CVD? Quick Review

25 Lesson 1 Click Next to attempt another question. A. A cardiovascular disease is a disease that affects the heart or blood vessels. Regular physical activity strengthens the heart and helps maintain a healthy weight. Quick Review - Answer

26 Lesson 1 Provide a suitable analysis. How can practicing healthy lifestyle behaviors now help you avoid cardiovascular disease in the future? Quick Review

29 Lesson 1 Cardiovascular Diseases 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. Communicable and Noncommunicable Diseases A noncommunicable disease is a disease that is not transmitted by another person, a vector, or the environment.
