Non Communicable Disease Prevention Lesson 32

Objectives Identify the causes, symptoms and treatment of several non-communicable diseases Identify the causes, symptoms and treatment of several non-communicable diseases

Non-Communicable Disease disease that is not transmitted by another person, vector or the environment disease that is not transmitted by another person, vector or the environment

Cardiovascular Diseases (CVD) disease that affects the heart or blood vessels (CVD) disease that affects the heart or blood vessels 61 million Americans have some form of the disease 61 million Americans have some form of the disease CVDs are responsible for more that 40% of all deaths in the US each year CVDs are responsible for more that 40% of all deaths in the US each year

Types of Cardiovascular Disease Hypertension Hypertension Atherosclerosis Atherosclerosis Diseases of the Heart Diseases of the Heart Angina Pectoris Angina Pectoris Arrhythmias Arrhythmias Heart Attack Heart Attack Congestive Heart Failure Congestive Heart Failure Stroke Stroke

Hypertension High blood pressure High blood pressure Blood pressure: force of blood created by the heart’s contractions and resistance of the vessel walls Blood pressure: force of blood created by the heart’s contractions and resistance of the vessel walls Normal pressure varies with age, height, weight and genetic factors Normal pressure varies with age, height, weight and genetic factors Major risks factor for other types of CVDs Major risks factor for other types of CVDs Pressure that is continually above the normal range will damage the hart, blood vessels and other bodily organs Pressure that is continually above the normal range will damage the hart, blood vessels and other bodily organs High blood pressure can be lowered with medication, weight management, adequate physical activity and proper nutrition High blood pressure can be lowered with medication, weight management, adequate physical activity and proper nutrition

Atherosclerosis Process in which plaques accumulate on artery walls Process in which plaques accumulate on artery walls Buildup due mainly to food choices Buildup due mainly to food choices High intake of saturated fats and cholesterol High intake of saturated fats and cholesterol Sometimes a blood clot forms in the area of the plaque, growing until it blocks the artery and causing damage to the tissues the artery supplies blood to Sometimes a blood clot forms in the area of the plaque, growing until it blocks the artery and causing damage to the tissues the artery supplies blood to

Diseases of the Heart Angina Pectoris Angina Pectoris Chest pain that results when the heart does not get enough oxygen Chest pain that results when the heart does not get enough oxygen Most commonly caused by atherosclerosis Most commonly caused by atherosclerosis Arrhythmias Arrhythmias Irregular heart beats Irregular heart beats Common, and often don’t cause problems. However, certain types are serious Common, and often don’t cause problems. However, certain types are serious Ventricular fibrillation: electrical impulses regulating heart rhythm become rapid or irregular Ventricular fibrillation: electrical impulses regulating heart rhythm become rapid or irregular Most common cause of a sudden cardiac arrest Most common cause of a sudden cardiac arrest Heart Attack Heart Attack Many are sudden and cause chest pain but 1 in 4 produces no symptoms at all Many are sudden and cause chest pain but 1 in 4 produces no symptoms at all Immediate response to stress on the heart Immediate response to stress on the heart Without emergency help, death will follow within minutes Without emergency help, death will follow within minutes Congestive Heart Failure Congestive Heart Failure Gradual weakening of the heart that it can not maintain its regular pumping rate and force Gradual weakening of the heart that it can not maintain its regular pumping rate and force Can be a result of high blood pressure, arthrosclerosis, heart valve defects or other factors Can be a result of high blood pressure, arthrosclerosis, heart valve defects or other factors Medications, good nutrition and adequate physical activity can help to manage congestive heart failure Medications, good nutrition and adequate physical activity can help to manage congestive heart failure

Stroke When arterial blockage interrupts the flow of blood to the brain When arterial blockage interrupts the flow of blood to the brain Can affect different parts of the body, depending on the part of the brain that is deprived of oxygen Can affect different parts of the body, depending on the part of the brain that is deprived of oxygen Can also occur as a result of cerebral hemorrhage, a condition in which a blood vessel in the brain bursts, causing blood to spread into surrounding brain tissue Can also occur as a result of cerebral hemorrhage, a condition in which a blood vessel in the brain bursts, causing blood to spread into surrounding brain tissue

Risk Factors for CVDs You Can Control: Figure 26.2 pg 679

Risk Factors You Can’t Control Heredity Heredity Children whose parents have CVD are more likely to develop CVD themselves Children whose parents have CVD are more likely to develop CVD themselves Gender Gender Men have a greater risk of developing CVD earlier in life and are at greater risk of having a heart attack than women Men have a greater risk of developing CVD earlier in life and are at greater risk of having a heart attack than women However, older women are less likely to survive a heart attack than men of the same age However, older women are less likely to survive a heart attack than men of the same age Age Age As people become older, they become more likely to develop CVD As people become older, they become more likely to develop CVD 80% of people who die of CVD are 65 or older 80% of people who die of CVD are 65 or older

Cancer Uncontrollable growth of abnormal cells Uncontrollable growth of abnormal cells Cancer can harm the body in various ways: Kill normal cells when they compete with them for nutrients Kill normal cells when they compete with them for nutrients Tumors put pressure on surrounding tissues and organs, interfering with body function Tumors put pressure on surrounding tissues and organs, interfering with body function Tumors can block arteries, veins, and other passages in the body Tumors can block arteries, veins, and other passages in the body Tumor: abnormal mass of tissue that has no natural role in the body Benign: noncancerous Benign: noncancerous Malignant: cancerous, spreading to neighboring tissues and through the blood or lymph to other parts of the body Malignant: cancerous, spreading to neighboring tissues and through the blood or lymph to other parts of the body Metastasis: the spread of cancer from the point where it originated to other parts of the body Metastasis: the spread of cancer from the point where it originated to other parts of the body
