Coronary arteries provide blood to the heart muscle. Coronary arteries provide blood to the heart muscle.

One Cause: atherosclerosis One Cause: atherosclerosis –arteries clogged and narrowed –the heart starved of oxygen and nutrients

Heart Attack and stroke Heart attack -a coronary artery suddenly blocked Heart attack -a coronary artery suddenly blocked stroke -similar to a heart attack, except occurs brain blood vessels stroke -similar to a heart attack, except occurs brain blood vessels High blood pressure and high cholesterol levels may contribute High blood pressure and high cholesterol levels may contribute

Blood Pressure Normal value = 120/80 Normal value = 120/80 Larger value = systolic pressure Larger value = systolic pressure Smaller value = diastolic pressure Smaller value = diastolic pressure

Blood Pressure High values damages your arteries, fatty deposits form on rough surface. High values damages your arteries, fatty deposits form on rough surface. Causes: including obesity, heavy alcohol use, family history of high blood pressure, high salt intake, and aging. A sedentary lifestyle, stress, low potassium intake, and resistance to insulin may also cause your blood pressure to rise Causes: including obesity, heavy alcohol use, family history of high blood pressure, high salt intake, and aging.

Cholesterol Cholesterol numbers Cholesterol numbers –Total cholesterol <200 –HDL>40 –LDL<100

Cholesterol Cholesterol levels can increase with: Cholesterol levels can increase with: –Diets high in saturated fats or trans fats –Obesity –Genetic basis

Cholesterol LDL — the "bad cholesterol" — collects in the walls of arteries, initiating "hardening of the arteries" or atherosclerosis LDL — the "bad cholesterol" — collects in the walls of arteries, initiating "hardening of the arteries" or atherosclerosis HDL — or "good cholesterol" — is associated with decreased risk. HDL — or "good cholesterol" — is associated with decreased risk.
