For some awareness, over 60% of people who suffer heart attacks and strokes have normal lipid panels (your cholesterol screens).
If you do have a physical planned, ask your doctor to expand on the test to include at least screening for Lipoprotein (a), also know as the "widow maker gene" (the hereditary component) as well as for your CRP level (it shows signs of inflammation being active in your cardiovascular system). No one is too young to get screened and if risk levels are high they can be managed by lifestyle changes and meds. Cardiovascular disease, in most instances, can be reversed.
Being in the business, more and more docs are screening for it to coincide with all of the preventative measures that are being incorporated by the system. Identify the stroke before you have to pay for the stroke, both health wise and dollar wise.
Hope this helps.
