Through this experiment can learn anatomy and function of the narrow the narrow question of whether there is its relevance. Approach in this study, 256 patients were cut first by coronary CT scan, the identified disease trillion over moderate stenosis after cardiac catheterization in the arrangements for the implementation of further coronary angiography to confirm the narrow disease trillion location. While the use of cardiac catheterization fractional flow reserve measurement instruments and measurement guide wire (RADIAnalyzer ®). Will measure the guide wire inserted into the coronary arteries disease trillion of the end can be narrow and cardiovascular disease and disease trillion trillion behind the front ends of the pressure difference between blood flow. If the blood pressure difference in the 0.78-0.80 below, is considered significant myocardial ischemia, if the blood pressure difference greater than 0.80, will be treated as normal without myocardial ischemia. The blood pressure difference between the measurements and the results of 256 CT scan-cut compared to observe whether the 256-cut computed tomography to determine the disease trillion more than moderate stenosis, and fractional flow reserve consistent with the measured data of the degree. Through the study found that patients with coronary artery disease is currently the case from the preliminary results, in the same anatomical location, fractional flow reserve and 256 off the value of the fault diagnosis of brain compared to the measured significance of ischemic do the same, in the same anatomical location, the 256 cut off the fault of the brain showed moderate disease trillion more than the narrow 256-MSCT 38.6%, FFR <0.80 were, identified coronary ischemia 35%, FFR> 0.80 who showed no coronary ischemia 26%。 The study concluded that the 256 cut off the brain tomography coronary inspection system is simple and conservative in nature, were cut off by the 256 brain CT screening, complex and intrusive during the inspection, not only can save medical resources, but also large number of people reached for examination, to protect public health.
