Although the total Cholesterol is a little high, your ratio of LDL/HDL is very good (3.0). I'm guessing you exercise often. I agree with Jon, I'm betting that simply watching your diet would make the total cholesterol reading go down. I have very aggressive heart disease and my doctor wants my LDL to be less than 75 and LDL/HDL ratio of 2.5. HDL is the 'good' cholesterol that chases the LDL 'bad' choleserol out of the arteries, HDL is raised by taking statin drugs but more by daily aerobic exercise. The fact that you have a family link to heart trouble makes it important that you keep your cholesterol in control, as you obviously are. I'd suggest contacting your clinic or local hospital where undoubtedly there are classes taught that explain the cholesterol issues, usually insurance covers some if not all of the course.
Your numbers are not terrible, but a little high. TC should be under 200 and LDL under 130, however with a family hgistory of CAD your doctor would most likely want to see your LDL under 100. Also, your HDL (good cholesterol) is high, which is good and will help keep your LDL in check. You should lower your number to an LDL under 100 and a TC around 170. This is not a large reduction and can most likely be done with some changes in life style with exercise and diet. If necessary, you may need to go to meds if this does not work, but it should, it's not a drastic drop.
Hope this helps,
Jon
