New Discoveries on a Fingertip Test for Screening Silent Heart Disease Promising Results of Recent Clinical Studies to be Presented during the 2009 American College of Cardiology Conference, March 29th - April 1st in Orlando

thallium nuclear scan. The study showed that those with coronary blockage and abnormal scan results often had low fingertip temperature reactivity. Dr. Budoff and colleagues also studied apparently healthy individuals with a family history of heart disease or with other cardiovascular risk factors. They discovered that the lower the fingertip thermal reactivity, the higher the chance of having a coronary blockage or calcium score >100 -both of which would place these individuals at a high risk of a future heart attack.

"The VENDYS technology was originally developed at our laboratory in the Texas Heart Institute while working on vulnerable plaque detection," said Dr. Morteza Naghavi, inventor of the VENDYS® technology. "Despite exciting developments in intracoronary plaque characterization, it became obvious to me that we needed a non-invasive and inexpensive way to screen and monitor at risk patients, simply because you can't cath asymptomatic people, nor can you put stable patients into CT or MRI machine every 3 months to evaluate their progress." He added, "Frankly, at the time, I didn't expect it to be so surprising in terms of its predictive value compared to risk factors. But now, looking at the data, it makes sense, because it does not measure an individual risk factor, like cholesterol; instead, it reflects vascular function which is affected by numerous risk and protective factors, much like blood pressure. Furthermore, unlike coronary calcium or carotid IMT, it is a dynamic marker and changes quickly with the progression and regression of the disease."

Every year, over 1.4 million heart attacks occur in the United States and many more worldwide. About half of these heart attacks happen in healthy-looking individuals who had no previous symptoms of heart disease. Had these individuals been tested by existing, cardiovascular risk factor-based screening tests on the day before their heart attack, the ma
