New progress in interventional therapy for coronary heart disease in China

Release date: 2009-03-31


Coronary heart disease is one of the major health killers in China. Statistics show that 42 out of every 105 deaths per year die from coronary heart disease. It is worth noting that the incidence of coronary heart disease in China has been increasing year by year in recent years. Recently, at the 2009 China Interventional Cardiology Conference held in Beijing, Gao Runlin, academician of the Chinese Academy of Engineering and chairman of the conference, said that in recent years, China’s interventional cardiology has made rapid progress, and the number of interventions increased from less than 10,000 in 1999. Nearly 190,000 cases have been reported so far.
More and more patients need to implant coronary stents to treat coronary heart disease. Clinical data published at the conference showed that patients with coronary heart disease received a new generation of everolimus-eluting stent for 2 years compared with the first-generation paclitaxel-eluting stent, which reduced the risk of major cardiovascular adverse events.
Professor Ge Junbo from Zhongshan Hospital affiliated to Fudan University said that "coronary heart disease has always been one of the most important diseases that threaten Chinese patients. In recent years, with the change of people's lifestyles, the incidence of coronary heart disease has gradually increased, and it has become younger. Trends. We have been expecting an innovative and effective treatment to help Chinese patients with coronary heart disease. The results of two clinical trials announced by the conference have brought us new hopes. I believe that the majority of Chinese patients with coronary heart disease will be eluting stents from new drugs. Benefit from it."
Regarding the localization of stents, Academician Gao said that the development situation has been very good in recent years. Some new stents have been put on the market, and some are in clinical trials. Domestic stents can reduce the economic burden of patients, and can also promote the price of imported stents. Recently, the academic research team led by Professor Fu Weiguo, a vascular surgeon at Zhongshan Hospital of Fudan University, has made new progress in the endovascular treatment of aortic dissection. This achievement has been published in the foreign authoritative professional magazine "Circulation", which has become a new milestone in the research of the treatment of aortic dissection in China. Fu Weiguo said that the research and development of domestic appliances is also the focus of research work. There is three patents for a stent for aortic dissection.
According to experts, the interventional treatment of chronic occlusive disease is very challenging in coronary intervention, and is regarded by many doctors as "the last bastion without being conquered." Based on Professor Ge Junbo and the 19 authoritative experts who participated in the discussion, the book "Interventional Therapy for Chronic Total Occlusion of Coronary Artery" was published in the International Conference after three years of publication. This is not only officially published at this international conference. It can be used as a guide for clinical cases and treatment strategies of interventional physicians in China, and it also further regulates clinical interventional treatment techniques.
In the radiological examination and interventional diagnosis and treatment, the use of contrast agents (contrast agents) is indispensable. With the increasing clinical application of contrast agents, contrast nephropathy has become an important cause of renal failure and has attracted the attention of the medical community. How to avoid damage to the patient's kidney and prevent the occurrence of contrast nephropathy? At this meeting, experts and scholars from home and abroad gave a detailed introduction to the current situation and development of clinical application of contrast agents in China, as well as the influence of contrast agent viscosity and contrast agent nephropathy. Through in-depth study of the pathogenesis, it is found that viscosity as an important physical and chemical index of contrast agents has an important impact on the occurrence of contrast nephropathy. Professor Chen Yunwei, director of the Department of Cardiology of the General Hospital of the People's Liberation Army, said that as a clinician, in the process of using contrast agents in high-risk patients, it is necessary to have a deep understanding of the characteristics of various contrast agents and the actual situation of patients, and to strengthen prevention. Control of kidney disease and diabetes, minimizing the amount of contrast agents, and performing interventional procedures in multiple stages.
In addition, as a powerful assistant to the cardiologist, a new generation of coronary imaging technology, OCT, has reached the stage of simultaneous use with Europe. OCT's full name is Optical Coherence Tomography, another new intravascular imaging method following X-ray, CT, MRI and ultrasound diagnostic techniques. It combines optical technology, ultra-sensitive detection technology and computer image processing technology to quickly obtain high-resolution microscopic images of cross-sections of blood vessels. To date, OCT is the highest resolution intravascular imaging technique with much higher accuracy than any existing cardiovascular imaging method, known as the "histological microscope in vivo." At present, Fuwai Hospital, Beijing Anzhen Hospital, Chinese People's Liberation Army General Hospital, Second Hospital Affiliated to Harbin Medical University, Beijing Electric Power Hospital, Shenyang Military Region General Hospital, Xijing Hospital, Tianjin First Central Hospital, Shanghai Zhongshan Hospital, Shanghai Tongji Hospital, the First Affiliated Hospital of Guangzhou Medical College and other units began to use.

The main features:

1)Ideal cold light effects

Using the new LED cold light source, ensure energy saving and environmental protection and long service life up to 80,000hours and more.

The temperature increase of surgeon`s head below 1℃. LED do not engender infrared ray and ultraviolet radiation, without the temperature

rise and tissue damage caused by halogen shadowless light, also it can accelerate the wound healing after surgery, and without Radiation pollution.

With color temperature constant and soft, LED is very close to the sunshine.

1) Excellent shadowless effect

Lamp with the most scientific radian and Multi point light source design, ensure better uniform illuminance. When the lamps are partially occluded,

also can achieve perfect shadowless effect.Lamp panel radius of gyration ≥182cm, the lamp can be pulled to vertical floor, convenient to any angle illumination.

2) Excellent deep lighting

It is based on modularize method by Computer Aided Design, focused to irradiating with more beams of LED. It produces the deep lighting which beams

more than 1200cm,the illumination of center up to 180,000Lux or more, and offer the color temperature that can be adjusted from 3700K to 5000K which

is close to sunshine. Absolutely, it really reflects the color of human tissue and satisfied by all kinds of operating light needs.

3) Advanced control system

The use of liquid crystal display button control, to meet the needs of the medical staff of different patients with the brightness of the operation.
