Of course, none of this predicts in the individual case. Also, there must be countless variables not taken into consideration. Consider also that any medication taken to ameliorate the condition brings its own bevy of risks. Finally, the drugs are hardly likely to guarantee their intended results, and may in fact be efficacious in only a small percentage of cases. (Thank you, Mitchell Silver, for that last point ... who also adds a further point: The severity of the heart disease in question needs to be specified, since in theory it could cover a range from severe to negligible.)
This is why, in the end, treatment (if any) is what is commonly called a matter of judgment ... and also preferences. So presented with the facts as stated -- let's say, 10-percent of folks like you (in some but of course not all respects) will (untreated, I presume....?) likely develop heart disease of such-and-such range of severity in the next ten years, and Medication X has been shown to avert or at least ameliorate heart disease in n percent of such cases, but also poses such-and-such risk of so-and-so side effects -- should your doctor prescribe or should you take the med? I think there's no "should" about it. The only question is: What will you do once you have reflected on the relevant facts?
