Volume is up from the average of 200k it was a year ago. Any thoughts?

Finance Home - Yahoo! Brian, based on this study the EBCT is needed for all those entering hospitals for chest pain. What do they consider a negative scan? Mayo Clinic study by: poobahitsy 4850 of 4864 I heard this Mayo clinic story on NPR today. Probably the reason for the increased activity. Also heard a fund manager was snooping around IMAT headquarters. Make of it what you will. CHEST PAIN EVALUATION A pilot study of 105 patients with chest pain found Electron-Beam Computerized Tomography (EBCT) to be a rapid and efficient tool for screening chest pain patients; it found that patients with negative results from EBCT -- a 10-minute, high-resolution scan of the heart -- can be discharged safely from the emergency department without further testing or observation. All 54 of the study patients who had negative scans had no cardiac events within 4 months of their emergency room visits. "Coronary artery disease is the major cause of mortality in the United States, and chest pain is one of the most common reasons for an emergency room visit, resulting in 5 million visits each year and 1.5 million admissions to the hospital," said Dennis A. Laudon, MD, an emergency medicine specialist at the Mayo Clinic in Rochester, Minnesota. "Chest pain is complex to evaluate because it is difficult to differentiate coronary artery disease from other causes, and this study shows the scan to be effective." Two to 5 percent of patients experiencing heart attacks are discharged from the emergency department without the heart attack being recognized. Because these people have higher mortality rates than patients whose heart attacks are diagnosed, emergency physicians commonly recommend hospital admission for all patients at risk of heart attack even though only a small percentage will have one. Initial 12-Lead ECGs and cardiac enzyme tests are only 35- to 50-percent sensitive in detecting acute myocardial infarction (heart attack), contributing to the development of chest pain observation units. Unlike some other cardiac testing, EBCT does not depend on severe coronary obstruction to flow for detection of coronary artery disease. Furthermore, the accuracy of the test is not limited by a patient's medications, ability to exercise, or baseline ECG abnormalities, and it costs a fraction of other commonly used cardiac tests (Use of Electron-Beam Computed Tomography in the Evaluation of Chest Pain Patients in the Emergency Department).
