Cardiovascular Diseases Incidence • • • High Blood Pressure - 50, 000 Coronary Heart Cardiovascular Diseases Incidence • • • High Blood Pressure - 50, 000 Coronary Heart Disease - 13, 900, 000 Stroke - 4, 000 Rheumatic fever/heart disease - 1, 800, 000 More than 1 in 5 males and females have some form of CVD

Deaths from CVD • Almost 1, 000 deaths in 2005 – CAD is #1 Deaths from CVD • Almost 1, 000 deaths in 2005 – CAD is #1 cause of death in US – Stroke is #3 cause of death in US • ~ 40% of all deaths • Since 1900, CVD has been the No. 1 killer in U. S • More than 2, 600 Americans die each day from CVD • CVD claims more lives than next 7 causes

Deaths from CVD • Approximately half the deaths are females and half are males Deaths from CVD • Approximately half the deaths are females and half are males • 36% of deaths occur prematurely (before age 75) • If all forms of major cardiovascular disease were eliminated, life expectancy would rise by 10 years; If cancer were eliminated, life expectancy would rise 3 years.

Coronary Heart Disease • • Single largest killer of males and females Almost 500, Coronary Heart Disease • • Single largest killer of males and females Almost 500, 000 deaths per year Half die within 1 hour of onset of symptoms In 48% of men and 63% of women who die suddenly, there were no previous symptoms

Women and CHD • Women suffer heart attacks an average 10 years later than Women and CHD • Women suffer heart attacks an average 10 years later than men • Since 1984, CVD has killed more women than men • 1 in 2 women will die from CVD; 1 in 26 will die from breast cancer.

Unalterable Risk Factors • Age • Gender • Heredity Unalterable Risk Factors • Age • Gender • Heredity

Alterable Risk Factors • • • Sedentary Life Style High Blood Pressure High Blood Alterable Risk Factors • • • Sedentary Life Style High Blood Pressure High Blood Cholesterol Smoking Diabetes Mellitus

Heart Attack Warning Signs • • • Chest Discomfort (angina pectoris) Discomfort in other Heart Attack Warning Signs • • • Chest Discomfort (angina pectoris) Discomfort in other areas of upper body Shortness of breath Cold sweat Nausea Light headedness

Cholesterol Types & Values • Major cholesterol types – High Density Lipoprotein (HDL) – Cholesterol Types & Values • Major cholesterol types – High Density Lipoprotein (HDL) – Low Density Lipoportein (LDL) – Very Low Density Lipoprotein (VLDL) • Total Cholesterol = HLD + LDL + VLDL – TC < 200 mg/dl – LDL < 130 mg/dl

Risk Ratio (RR) • RR = Total Cholesterol/HDL – if RR > 4. 0 Risk Ratio (RR) • RR = Total Cholesterol/HDL – if RR > 4. 0 = increased risk – if RR < 4. 0 = decreased risk • You can lower your risk by either increasing HDL or decreasing TC or both

Risk Ratio Example • Total Cholesterol = 250 mg/dl – HDL = 40 mg/dl Risk Ratio Example • Total Cholesterol = 250 mg/dl – HDL = 40 mg/dl – RR = 250/40 = 6. 25 (risky) • Total Cholesterol = 250 mg/dl – HDL = 65 mg/dl – RR = 3. 8 (good)

Lowering Your Cholesterol • Consume less saturated fat in the diet – eat lean Lowering Your Cholesterol • Consume less saturated fat in the diet – eat lean meat and low fat dairyfoods – eat less processed foods – cook only with mono- or polyunsaturates • Consume less cholesterol in the diet – eat lean meat and low fat dairy foods – use only vegetable oils (no tropical oils)

Hypertension • Ideal pressure is < 120/80 • Hypertension is >140/90. • Hypertension can Hypertension • Ideal pressure is < 120/80 • Hypertension is >140/90. • Hypertension can be reduced by: – Regular exercise program – Reduced sodium intake – Drugs

Stroke Warning Signs • Sudden numbness or weakness of face, arm, leg, especially on Stroke Warning Signs • Sudden numbness or weakness of face, arm, leg, especially on one side of body • Sudden confusion, problems speaking or understanding • Sudden trouble seeing in one or both eyes • Sudden loss of coordination, trouble walking, dizzy • Sudden severe headache with no known cause

Unalterable Stroke Risk Factors • • • Age Heredity Race Gender Previous transient ischemic Unalterable Stroke Risk Factors • • • Age Heredity Race Gender Previous transient ischemic attack (TIA)

Alterable Stroke Risk Factors • • High Blood Pressure Smoking Diabetes Mellitus High Cholesterol Alterable Stroke Risk Factors • • High Blood Pressure Smoking Diabetes Mellitus High Cholesterol Physical Inactivity Obesity Atrial fibrillation Carotid or peripheral artery disease

Cancer • • • Second leading cause of death Prostate - 334, 000 (99%) Cancer • • • Second leading cause of death Prostate - 334, 000 (99%) Breast - 180, 200 (97%) Lung - 178, 000 (14%) Colon & Rectum - 131, 200 (61%) Testicular - 7, 200 (91%)

Early Warning Signs • • C - Change in bowel or bladder habits A Early Warning Signs • • C - Change in bowel or bladder habits A - A sore throat that does not heal U - Unusual bleeding or discharge T - Thickening or lump I - Indigestion or difficulty swallowing O - Obvious change in wart or mole N - Nagging cough or hoarseness

Risk Factors • Heredity • Nutrition – high fat – low vegetables & fruits Risk Factors • Heredity • Nutrition – high fat – low vegetables & fruits (anti-oxidants, fiber) • Smoking • Environment • Sedentary Lifestyle

Causes of Skin Cancer • • Total amount of sun received Acute overexposure (sunburn) Causes of Skin Cancer • • Total amount of sun received Acute overexposure (sunburn) Most receive 80% of exposure by age 18 1 in 7 will develop some form of skin cancer in their lifetime

Tanning • Tanning is the skin’s normal response to UV light • Tanning is Tanning • Tanning is the skin’s normal response to UV light • Tanning is protective reaction to prevent further injury • Tanning does not prevent skin cancer

Factors Determining UV Level • UV light is greater today than in the past Factors Determining UV Level • UV light is greater today than in the past due to reduction in ozone layer • The following increase UV light: – Altitude – Proximity to the equator – Less cloud cover

Risk Factors for Skin Cancer • Genetics – Northern European heritage – Fair skin Risk Factors for Skin Cancer • Genetics – Northern European heritage – Fair skin • Environment – Geography – Sun Exposure

Types of Skin Cancer • Basal Cell Carcinoma • Squamous Cell Carcinoma • Melanoma Types of Skin Cancer • Basal Cell Carcinoma • Squamous Cell Carcinoma • Melanoma

Basal Cell Carcinoma • Most common form of cancer • Occurs in basal cells Basal Cell Carcinoma • Most common form of cancer • Occurs in basal cells at the bottom of the epidermis • Occurs most often in males • Occurs on most exposed areas: face, ears, neck, scalp, shoulders, back • Rarely does it go deeper than epidermis and metastasize
