Treatment of heart disease has made great strides in the last 50 years. Not only information about the risks, symptoms, and causes is increasing. The number of options available to treat different types of heart disease is also increasing.
What are stents?
A stent is a small tube made of wire mesh. This tube is inserted into a partially blocked artery to open it and allow blood to flow more freely. You can find the best medical stents manufacturers via www.pobamedical.com.

When the stent stays in place
Stents are permanent. It is designed to stay in the artery and stay open. It is expected to increase blood flow to the heart and reduce symptoms of heart disease for years to come.
However, in these years, are stents effective in treating heart disease? Or is it a potential problem?
Within a few weeks of placing the stent, the inner lining of the artery begins to grow on the metal surface of the tube. These growths tend to clog the arteries again. Additional plaque may also form. When this happens, the arteries close in the same place, and the symptoms of heart disease return. The most noticeable symptom is probably chest pain.
To avoid this growth, pharmaceutical companies have developed new stents to replace bare-metal stents. The new stent is coated with a slow-release drug.
Medications prevent the arteries from closing again. In both cases, the patient will have to take anticoagulant medication, but we expect the newer stents to be effective in the long term.
