February is American Heart Month and Medvica International can’t think of a better opportunity to ask your physician about your endothelial function.
According to the American Heart Association, 50 percent of coronary deaths take place in people with no previous symptoms including elevated cholesterol levels. However, a new seven year study by the Mayo Clinic released in 2009 suggests measuring blood vessel health, or endothelial function, can aide in diagnosis of a wide variety of medical conditions including coronary artery disease, heart attack, stroke, sleep apnea, pre-eclamptic toxemia and even erectile dysfunction.
Physicians now have a new easy-to-use, non-invasive test to measure endothelial function and Medvica International is among the first companies to market the device in North America. The Endo-PAT2000, developed by Israeli company Itamar-Medical, was approved by the U.S. Food and Drug Administration in 2003 and is already used in 40 other countries.
“The connection between endothelial dysfunction and cardiovascular health was one of the most significant medical discoveries of the last decade and earned the Nobel Prize in Medicine in 1998 for three Americans,” says Sharon Snyder, chief executive officer for Medvica. “But until recently there wasn’t a credible, FDA approved device to measure endothelial dysfunction. Endo-PAT’s capabilities have now been validated by hundreds of studies and tests at the nation’s top medical organizations including the Mayo Clinic, Harvard University, the New England Medical Center and the Cleveland Clinic.”
Endo-PAT looks for signs of heart disease and other conditions by using sensors that measure blood flow through a patient’s fingers. Endothelial cells line the inner walls of blood vessels, lymph vessels, and the heart, and damage to them may be an early sign of heart disease. The device is small enough to sit on a table and in a 15-minute, office-based test clinicians can now have a reliable and reproducible index of endothelial function.
The seven-year Mayo Clinic and Tufts-New England Medical Center study published in April 2009 suggests that a patient with low risk (based on Framingham Risk Score) but high endothelial dysfunction is 300 percent more likely to have a heart attack than a patient with low risk and no endothelial dysfunction. In the study, 49 percent of patients whose Endo-PAT test indicated poor endothelial function had a cardiac event during the seven-year study.
