That is interesting to know what can one do to find out if he or she is in great risk of having heart attacks. I believe besides testing it, it is important to take note as well to address the concerns of high cholesterol, high triglycerides and high homocysteine level with a natural supplement called Bios Life:

In most cases, these heart attacks are caused by soft plaque ruptures (no symptoms, no abnormal diagnostic tests, and few or no risk factors).

There is a viable solution to identify if you have soft plaque building in your arteries (regardless if you are in shape and hav no elevated risk factors).

It is called a Carotid IMT ultrasound test. This test measures the inflammation in the innermost layers of your carotid arteries (neck). Its non incasive and will detect the earliest signs of structural vascular damage (pre-disease and early disease). Your physician can then treat you clinically, rather than waiting for you to have an event, or become so clogged (moderate and advanced disease)that its time for surgery.

this test is becoming more readily available to consumers and physicians, but with all new procedures-the medical establishment is slow to catch on.
