19) high cholesterol levels have been known to be a contributing factor to heart disease
and death due to cardiovascular disease for many decades. in the 1970’s, scientists used
this information to develop a hypothesis that giving a medicine to reduce blood
cholesterol levels could reduce the chances of developing cardiovascular disease or
dying from cardiovascular disease. they tested a group of people living in a town called
framingham, massachusetts. this study became known as the framingham study and it is
very well known, because it did not support the hypothesis that giving cholesterol
lowering medications would reduce the risk of developing or dying from cardiovascular
disease. does this mean that high cholesterol is not a risk factor for heart disease? what
does this demonstrate about the scientific process, especially as it pertains to human
studies? you can find a copy of the study online and read it, if necessary.
