Next generation cardiac risk test

While high cholesterol level is generally seen as indicative of higher risk of heart attack, in 50% of cases, the patient actually had normal cholesterol levels. A more accurate risk test aimed for people identified as the medium risk group is available nation-wide.

Dr. Phil Tsao, Professor of Cardiovasular Medicine at Stanford University also points out that, it is very difficult to decide on the most suitable treatment plan for people categorized as having intermediate risk for heart attacks.

“Either send them along and ask them to manage the risk factors, increase their activities, while some physicians are more aggressive and would start a pharmacological treatment. But it is really a decision they have to go on with their experience, or their knowledge of the patient” he said.

Years of research yielded the discovery of 7 protein biomarkers in the blood, which are associated with formation of vulnerable plaques in the blood vessel. 75% of heart attacks are caused by rupture of the vulnerable plaques.

According to Dr. Tsao, these proteins are indicative of the biological activity of the vulnerable plague. With the assessment of an individual’s risk level, anatomical data of the presence of plaques in the blood vessel, as well as the insight about the biological underlying of the plaques, it would be helpful to tell if any of the plaques is more apt to rupture and causes heart attack.

MIRISK VP is the renovative blood test to identify the presence of the 7 proteins at stake. Dr. Tsao says research studies had shown that the test, which is aimed primarily for people between 40 to 80 and are found by initial testing as of medium risks, enables better risk categorization.

The test is available nationwide in the United States, as well as some other countries. Blood sample would be drawn from patients and sent to the specific lab in Irvine, CA for examination. Results will be available in 7 to 10 business days.
