Release date: 2014-08-28 According to reports, scientists use cassava root extracts made from pudding to make small implants that can be used to treat angina. This device can avoid the common equipment. Side effects. The device looks like a tiny, narrow roller that can be implanted into a blocked artery to widen it, keeping the artery open, and the tubule will dissolve automatically after a few months. Angina is a type of chest pain caused by insufficient local blood supply to the heart. Like other muscles, the heart muscle also requires a stable oxygenated blood flow. If the artery is The deposited thrombus is partially blocked, and the heart cannot get enough blood, which can cause angina. A common treatment for angina pectoris is medication, such as nitroglycerin, which dilates myocardial blood vessels during the onset of angina pectoris. But patients who are unable to relieve angina by medication It is necessary to undergo surgery - coronary angioplasty. Surgery implants a small balloon into the occlusion artery, swells the fat after the balloon is inflated, and then places a metal stent in the stenosis to keep the blood vessels open. Although metal stents are very effective in treating angina, the stent itself can cause thrombosis, leading to vascular obstruction and heart disease. For prevention Thrombosis, implanted stent patients need long-term use of blood thinning drugs, such as aspirin. However, medication can also cause side effects such as headache and chest pain. Permanent metal stents cause the blood vessels to fail to return to their normal shape, reducing their flexibility. Locally increases the risk of inflammatory reactions in the stent, metal stent Implantation will also prevent the patient from undergoing a heart scan later. Implants made of new materials can widen blood vessels and carry sirolimus at the same time to prevent plaque formation after implantation. The implant will automatically decompose after a few months of implantation, and will not cause a risk of thrombosis in patients, and does not require long-term medication. The implant material is automatically biodegradable and extracted from tapioca starch and sugar cane. It is implanted in a similar manner to a metal stent, and the surgical procedure requires local anesthesia. The researchers are currently investigating implants in 30 patients with angina. The trial is a four-center clinical trial involving China Zhejiang University learn.
