Understanding Heart Disease: Types, Symptoms, and Prevention

1. Chapter 14 Lesson 2 Heart Disease Teacher’s notes are available in the notes section of this presentation. Next >>

2. A group of disorders that cause a thickening and hardening of the arteries • arteriosclerosis A condition that occurs when fatty substances build up on the inner lining of the arteries • atherosclerosis A serious condition that occurs when the blood supply to the heart slows or stops and the heart muscle is damaged • heart attack

3. A disease in which the pressure of the blood on the walls of the blood vessels stays at a level that is higher than normal • hypertension A serious condition that occurs when an artery of the brain breaks or becomes blocked • stroke A surgical procedure in which an instrument with a tiny balloon, drill bit, or laser attached is inserted into a blocked artery to clear the blockage • angioplasty

4. In this lesson, you will learn to • identifytypes of heart disease. • explainhow to reduce the risk of heart disease. • describehow heart disease is treated. • analyzethe influences of food advertising on heart health. • explainhow strokes and hypertension are related to heart disease.

5. What Is Cardiovascular Disease? Cardiovascular or heart disease is any condition that reduces the strength of the heart and blood vessels. Sometimes, heart disease is due to heredity, but it is usually related to lifestyle. People who Smoke get very little exercise have other unhealthy habits like poor diet are more at risk for developing heart disease.

6. The coronary arteries Bring blood to the heart From the lungs Oxygen Rich Types of Coronary Heart Disease If the coronaryarteries are clear,blood flows freely. The heart is a musclethat pumps blood through the body. A healthy coronary artery Is free of fatty substances Blood can flow through Coronary arteries onthe surface of the heartsupply it with oxygen-rich blood. An unhealthy coronary artery has a buildup of fatty substances that partially block the flow of blood If the coronaryarteries are blocked,coronary diseasebegins to develop. Veins on the hearttake oxygen-poorblood away.

7. Types of Coronary Heart Disease Arteriosclerosis is a group of disorders that includes atherosclerosis. arteriosclerosis A group of diseases that cause a thickening and hardening of the arteries atherosclerosis A condition that occurs when fatty substances build up on the inner lining of the arteries When buildup collects inside the arteries, it takes up space needed for blood to flow through. If the coronary arteries become blocked with too much buildup, the heart may not get enough oxygen.

8. A Heart Attack A heart attack can happen if the heart does not get enough oxygen from the blood. heart attack A serious condition that occurs when the blood supply to the heart slows or stops and the heart muscle is damaged.

9. A Heart Attack Symptoms of a Heart Attack for Males • Chest pain/pressure • Upper body pain – arms, left shoulder, jaw, stomach • Rapid or irregular heart beat • Upset stomach – indigestion, nausea or vomiting • Shortness of breath –even your resting • Dizziness, light headedness or fainting • Confusion, severe anxiety • Cold sweat Each heart attack is different.

12. Other Problems of the Circulatory System Hypertension can lead to a heart attack or a stroke. hypertension A disease in which the pressure of the blood on the walls of the blood vessels stays at a level that is higher than normal stroke A serious condition that occurs when an artery of the brain breaks or becomes blocked

13. Other Problems of the Circulatory System Hypertension: People who have hypertension can manage the condition by following a healthful eating plan, exercising regularly, avoiding stress, and taking medicine if needed. Stroke: Like the heart, the brain needs plenty of oxygen and nutrients to function. If an artery leaks or develops a thick mass called a clot, blood flow to the part of the brain is interrupted, causing damage. The effects of a stroke depend on what part of the brain is affected.

14. Preventing Heart Disease Eat healthful foods. Limit cholesterol,trans fats, and saturated fats. Manage stress. Participate in regularphysical activity. Stay tobacco free. Maintain a healthy weight. Stay alcohol free.

15. Treating Heart Disease Angioplasty is a popular method for treating heart disease. angioplasty A surgical procedure in which an instrument with a tiny balloon, drill bit, or laser attached is inserted into a blocked artery to clear a blockage

16. Treating Heart Disease Other methods used to treat heart disease are: • Medications • Pacemakers • Bypass surgery • Heart transplants
