Annual U.S. Cardiovascular Disease Mortality
CVD has been the leading cause of death in the United States every year since 1900, with the exception of 1918, when there was a worldwide flu pandemic

Examples of CVDExamples of CVD• Hypertension—a common, often asymptomatic disorder
characterized by elevated blood pressure persistently exceeding 140/90 mm Hg.
• Coronary Heart Disease—a general term that describes diseases of the heart caused by atherosclerotic deposits, or plaque, that result in a narrowing of the coronary arteries.
• Atherosclerosis – A chronic disease in which cholesterol and other fats are deposited
to the inner walls of the coronary arteries, reducing circulation to the heart

response to an interruption of blood supply• Stroke

Risk Factors for Cardiovascular Disease
Risk Factors for Cardiovascular Disease
• The Framingham Heart Study (1948 – Present)
– Landmark prospective study of demographic, biological, psychological risk factors in CVD
• Uncontrollable Risk Factors– Age, gender, family history, race/ethnicity– Testosterone
• Elevates LDL (bad) cholesterol– Estrogen
• Neutralizes oxygen free radicals that may contribute to vascular damage
• Controllable Risk Factors– Hypertension, body weight, diet, smoking, Type II diabetes, stress / hostility

Quit Smoking! Quit Smoking!
• In just 20 minutes after quitting, blood pressure decreases
• After 24 hours, the chance of heart attack decreases
• In just a year after quitting, the excess risk of coronary heart disease is decreased to half that of a smoker

• Type A’s have more:– rapid blood clotting– higher cholesterol and triglyceride levels under
stress– greater autonomic arousal, elevated heart rate, and
blood pressure in the face of challenging events– “combat ready” hyperreactivity

patients modify hostility, hurriedness, and negative emotions reduced risk of a second MI and total mortality rates by 50%
