risk
.
This interactive tool measures how
smoking—independent of other risk factors—affects your chance of having a heart
attack in the next 10 years. The tool uses the values you enter to calculate
your risk. The information is based on the Framingham Heart Study. During the
past 50 years, the Framingham Heart Study has studied the progression of heart
disease and the risk factors of heart disease. The data were then developed
into a risk assessment by the U.S. National Cholesterol Education Program
(NCEP), part of the National Institutes of Health. 1
The values you enter include your age and
gender. The tool uses a systolic blood pressure of 120
millimeters of mercury (mm Hg), an
HDL cholesterol measurement of 55
milligrams per deciliter (mg/dL), and a
total cholesterol measurement of 200 mg/dL to
calculate your risk based on smoking alone.
In the real world,
smoking has some additional negative effect on both cholesterol and blood
pressure. If you smoke and also have other risk factors for heart disease, your
risk may be higher than this tool says it is.
