A new diagnostic technology for coronary heart disease independently researched and developed by Chinese scientific research team has improved the accuracy rate of conventional coronary angiography by 33%. It has been officially approved by the State Drug Administration and will make up for the shortcomings of scarcity of accurate assessment tools for coronary heart disease in China.
According to the "China Cardiovascular Disease Report 2017" issued by the National Cardiovascular Center, the number of cardiovascular patients in the country has reached 290 million, including 11 million patients with coronary heart disease. For a long time, most domestic patients have used conventional coronary angiography, and the accuracy needs to be improved. The internationally recognized high-precision coronary heart disease assessment technology requires complex surgical procedures and consumables with a cost of 10,000 yuan, resulting in a low domestic application rate.
This new technology, developed by the research team of Shanghai Jiaotong University, is called the Quantitative Flow Fraction (QFR) measurement system. It performs three-dimensional reconstruction and hemodynamic analysis of coronary arteries through image data. No additional surgery, consumables and drugs are needed. .
A multi-center clinical study led by the Fuwai Hospital of the Chinese Academy of Medical Sciences shows that the technique can quickly assess coronary function within 4 minutes, and the accuracy is consistent with the current world "gold standard" results, which is more accurate than conventional coronary angiography. Increase by 33%.
"The new technology will become a good doctor's staff, help to accurately determine whether coronary heart disease patients should not put stents, put a few stents and other issues, reduce the cost of accurate prevention and treatment of coronary heart disease." Director of Institute of Biomedical Instruments, Shanghai Jiaotong University, China Academy of Engineering Academician Chen Yazhu said.
Innovative clinical research brings innovation in diagnosis and treatment strategies, which is one of the important reasons for the decline in cardiovascular mortality. Gao Runlin, chairman of the Chinese Medical Association Cardiovascular Branch and academician of the Chinese Academy of Engineering, said that QFR has a very high accuracy and sensitivity. According to the results, it can be judged which patient should be treated and which patient should be treated in the course of coronary heart disease. Has great health economic benefits.
