rating systolic. diastolic
normal. 120 or lower. 80 or lower
prehypertension 121-139. 81-89
hypertension. 140 or higher. 90 or higher
Coronary Heart Disease (CHD)
Give this one a try later!
-major form of CVD
-the arteries that supply the heart with oxygen and nutrients are narrowed
by fatty deposits -> process of atherosclerosis
-narrowing of the coronary arteries diminishes blood supply (therefore
, diminishes oxygen supply) to the myocardium, which can precipitate a
myocardial heart infarction

Family History, Personal History, Age, Gender (sex), and race/ethnicity
Framingham Heart Study (ongoing)
Give this one a try later!
study of entire community of Framingham, MA began in 1948 in an effort to
determine which factors were related to the development of CHD
-1960,1961 the first results were published that showed cigarette smoking,
cholesterol, and high blood pressure were risk factors for CHD
-1967 data from this study were published that showed a link between
physical activity and reduced risk of CHD

, -single leading cause of death in US, accounting for 20% all deaths and half
of CVD deaths
-more than half of the people who died suddenly from CHD had no
previous symptoms
-80% of deaths from CHD in people under the age of 65 occur during the
first heart attack
-risk of death is greater in the least educated segment of the population
homocysteine
Give this one a try later!
high concentrations of this amino acid in the blood is thought to enhance
plaque formation and subsequent blockage of arteries
- intermediate amino acid in the interconversion of 2 other AA- methionine
and cysteine; interconversion requires B vitamin Folate (folic acid) and
vitamins B6 and B12
large # of people have high levels of this due to
-genetic inability to metabolize the AA
-deficiency in the vitamins required for its conversion
