The new extracorporeal counterpulsation introduced by the Department of Internal Medicine of our hospital is a new non-invasive physiotherapy technique that is widely used in many ischemic diseases. The unique feature of extracorporeal counterpulsation therapy is that it accelerates intravascular blood flow in a non-invasive, relaxing and comfortable manner. Its effects include: 1. Maintaining effective blood circulation and oxygen operation throughout the body, improving blood supply to important organs such as lungs, brain and kidneys, thus improving their functions, returning human body functions to normal balance, improving mental and physical strength, and enhancing work efficiency and quality of life. 2.Increase the blood supply to the heart muscle, improve the metabolism of the heart muscle, relieve the heart disease and promote the recovery of the function. Part of the work instead of the heart, reduce oxygen consumption, and facilitate recovery. 3.It can improve the blood flow shear stress, promote the release of vascular growth factor, and promote the development of collateral vessels. The main treatment of extracorporeal counterpulsation: 1, ischemic cardiovascular diseases including: stable angina pectoris, asymptomatic myocardial ischemia, old myocardial infarction with myocardial ischemia. 2. Ischemic cerebrovascular diseases include:cerebral arteriosclerosis, transient ischemic attack (TIA), cerebral infarction, vertebrobasilar artery insufficiency (including vertebral artery cervical spondylosis), vertigo syndrome (cerebral and cervical origin), senile dementia, vascular dementia, vascular headache. 3. Ischemic eye diseases include: central retinal artery embolism, central plagioretinal chorioretinopathy, ischemic optic neuropathy. 4. Ischemic ear disease includes: sudden deafness. 5.Ischemic limb diseases include: atherosclerotic vascular occlusion, thrombo-occlusive vasculitis, peripheral circulation disorders. 6.People with hypertension, diabetes, hyperlipidemia, obesity, family history of cardiovascular disease, smoking, lack of physical activity and other cardiovascular risk factors to prevent and treat cardiovascular diseases. 7, prevention of fatigue, subhealthy people and health care for the elderly. According to a large amount of clinical data, extracorporeal counterpulsation therapy does not have any side effects and its efficacy is very precise. The U.S. government has therefore approved external counterpulsation therapy as a social insurance model. The United Kingdom, Germany, France, Japan, India, the Middle East, Southeast Asia and many other countries have also started the clinical application of extracorporeal counterpulsation and achieved convincing results in the medical field. The metabolism and physiological functions of all parts of the human body depend on adequate blood circulation. Blood flows through the blood vessels of the whole body and brings oxygen and nutrients to all parts of the body, while taking away harmful substances (free radicals, peroxides, etc.) produced by metabolism and expelling them from the body through the kidneys, intestines and skin. The thickening of blood and narrowing of blood vessels prevent all parts of the body from receiving sufficient oxygen and nutrients, and accumulate more and more harmful substances, leading to cardiovascular and cerebrovascular diseases. The in vitro counterpulsation accelerates blood circulation and has a positive effect on human health. This artificially formed “second large pulse” with high pressure and high flow rate repeatedly rushes out, accelerates blood circulation, promotes metabolism and corrects the metabolic disorders of local hypoxic tissues. Therefore, in addition to treating cardiovascular diseases, extracorporeal counterpulsation is also effective for cardiovascular and cerebrovascular health care, maintenance, recovery from athletic fatigue, diabetes, functional sexual dysfunction and other related diseases.
